Square Gears
This video
demonstrates square gears and other oddly shaped cogs. We can’t think of a use but it’s interesting none-the-less. [via
Tinkernology
]
Cooking with Lasers
It’s late and you’ve been at the workbench for quite some time. But why go to the kitchen for a snack? Grab a couple of 1 watt lasers, hot glue a kernel of corn to a DC motor, and
you’ll have popcorn in no time
.
Calling this a simulator just doesn’t do it justice
Okay, so
this link is a Lexus commercial
. But it’s worth watching to see the footage of this driving simulator. Inside that pod is an actual automobile surrounded by a 360 degree screen. The room has a full x and y axis to move the pod (and the car) as you drive through the simulated world. It’s like someone gave a bunch of geeks an unlimited budget and say “go nuts”. [Thanks Luke]
What takes the most time in your hacking adventures?
Everyone whose spent some time in web design has run across the peculiar rendering bugs and workarounds associated with Internet Explorer.
Internet Explorer Stole My Life
aims to tabulate the collective time wasted from the lives of developers. We think it’s hilarious because spending the same amount of time meeting
W3C standards
and this problem would go away. But [Caleb] mentioned something interesting when he saw this site: What part of your hacking adventures wastes the most time? We’d love to hear about it in the comments.

I’m guessing you could fit 16 or so aircraft simulator bays in the same space they’ve dedicated to one simulator. of course, they don’t have train 12000 drivers per year, so they can get away with one big, expensive sim.<p.Sims are are a large part of my job.

Hackvision Is Build-your-own Retro Game

If you wanted to try your hand at programming some retro games Hackvision can jump-start the process. It is
an Arduino-based game console in a controller format
. You get four directional buttons and one function button. It has two RCA jacks for mono audio, and black and white video.
We’re happy to find that there’s
information about game development
that will help you follow along with the Space Invaders and Pong examples. The system uses the Arduino TVout library for video, which is robust and fairly easy to interact with. But once you see the game play in the video after the break it’ll be hard to resist building one of these. Don’t forget, this is Arduino based. If you already have an Arduino that uses an ATmega328 you just need to build the audio, video, and button circuits.
[Thanks Franz]

It is a nice trade-off between RAM useage and external hardware (only a few diodes and resistors are needed).I needed it to work with a normal horizontal screen and with a vertical screen (monitor on its side). For that reason I cut the display area down to 30×30 8×8 blocks so everything can rotate perfectly based on just one tile map.The only down side is that the SPI interface takes an extra clock cycle to reset for the next byte, so an 8×8 block becomes an 9×8 block.

Lightsaber Color Selector

"color",
"lightsaber",
"pic",
"rgb",

[George Hadley] developed a nice setup to
control the color of a replica Lightsaber
. A small PCB houses a PIC 18F2221 and three switching transistors for the colors. A powerful LED resides in the tip of the handle, lighting up the diffuser that makes up the blade. But our favorite part is the control scheme. He’s embedded a small RGB LED in the handle, giving feedback as to which color of light can currently be adjusted (red, green, or blue). One button scrolls through the colors and a slide potentiometer adjusts that them.
We wouldn’t go as far as calling this a Halloween prop, we think it’s better suited for
serious replica builds
. But it would make an amazing addition to the little one’s costume. See it in action after the break.

What weighs more than 500 pounds, produces 500 kilovolts, and we don’t recommend you try at home in any way shape or form? If you guessed a
rock disaggregation device
, you’re correct!
We also accepted lightning generators as correct answers
. Using high voltage electricity, a rock can be split apart down to its grains without destroying the precious minerals inside; unlike traditional grinding and mechanical techniques that often ruin the sample. All it takes is a massive hydro pole transformer, five 1uf 100 kilovolt capacitors, eight hand wound inductors, and two massive cojones to stand within 20 feet of the thing while it’s going off. Video after the divide.

I’ve seen small scale gun stuff (basically, you replace gunpowder with air and high voltage) but never anything of this size. My hat is off to you.Once upon a time, this was one of the methods used to extract certain necessary elements fromrock, but there was war and a certain amount of secrecy involved. It was rediscovered a couple of times in the 70s, but certain folks bought the companies out and put a blanket on it… you can automate the process so that dull rock and sand goes in and glowing powder comes out.By the mid 90s it had been invented so many times that the cat was obviously out of the bag, and a canadian company started to run with it. It was invented in Korea and Germany as well.There is a reverse version of this used to coat materials, mix alloys of weird materials and create all kinds of things, which I suppose is still a hush kind of thing. Rather than using the 1930’s style 12 times a minute, they dump current at audio range and higher frequencies, and sometimes modulate it. No snapping, more of a squeal.This is easily the coolest thing I’ve seen on hackaday, Brad. Mad Props!Professor, be careful about showing off high energy devices. You might talk to burt swank about his run-ins with the folks who don’t like physics and worry for a living, or a guy I know who was playing with laser ionization (make a path in the air, shoot tungstein particles down it with HV, typical Tesla crap) and came very close to a visit.I expect amateur fusion experiments to be illegal within 10 years.",

I know 5 people will shout me down, but they’re likely to be pack-a-day smokers. :)Let me throw in my two cents about the blowouts.Basically, there’s a reason why spherical chambers get used for high pressure physics. Your vessel was much weaker than it needed to be because you didn’t provide a curved surface on the bottom.The punchline is that you were using a single anode point – and so the blast was basically a acting like a shaped charge.

A similar process could be causing your shockwave to only move in one direction inside your containment vessel.In EDM the workpiece is immersed in a dielectric fluid which arcs when a certain voltage is reached.

This circuit board is from the USB dongle of a Girl Tech IM-ME. [Joby Taffey] took it apart and
poked around to learn its secrets
. These dongles come along with the pink pager that has become a
popular low-cost hacking platform
. But we haven’t seen much done with the dongle itself up until now.
[Joby] used
the OpenBench Logic Sniffer
to gain some insight on what’s going on here. The board has two chips on it, a Cypress CY7C63803 USB microcontroller which talks to the computer over USB and also communicates over SPI with a Chipcon CC1110 SoC radio. It looks like reprogramming the Cypress chip is a no-go, so he went to work on the CC1110. The inter-chip communications data that he acquired by sniffing the SPI lines gave him all he needed to reimplement the protocol using his own firmware. As a proof of concept he to reflashed the CC1110 and can now send and receive arbitrary commands from the dongle. There’s a tiny video after the break showing a script on the computer turning the dongle’s LED on and off.

EvalBot: Arrival And Assembly

"ti"
] |
[Chris Muncy] just received his EvalBot from TI and
took some pictures of the assembly process
. He was one of the lucky folks that
picked up the kit for just $25
using a short-lived coupon code. Seeing the kit makes us wish we had ordered one. There is some assembly required but as you can see, it’s pretty much just mechanical assembly of the wheels and the front bumper arms.
We think the wheel design is quite good. It consists of two small gearhead motors mounted on the rectangular PCB parts that you can see on the right portion of the image above. Those mount to the circular mainboard using metal L brackets. The wheels themselves are three circular pieces of PCB, one with a smaller diameter sandwiched in between its two larger cousins. This creates a channel that is perfect for a neoprene O-ring to give the wheel traction. The main board uses an optical sensors and a hole through all three parts to function as a rotation counter.
It’s a fancy piece of hardware and we can’t wait to see what you can do with it! If you’ve got one,
we want to hear about your adventures
.

We love looking at hardcore electronics projects with a beefy microcontroller and hundreds, if not thousands, of lines of code at its center. But everyone needs to get there somehow.
This tutorial series aims to make you comfortable programming the
Atmel
AVR line of microcontrollers
. Whether you’ve never touched a microcontroller before, or you’ve cut your teeth with dozens of Arduino projects, this will help you get right down to the hardware and give you the confidence to build anything.
Series roadmap:
AVR Programming 01: Introduction
AVR Programming 02: The Hardware
AVR Programming 03: Reading and compiling code
AVR Programming 04: Writing code
Prerequisite knowledge
Here’s the good news: I’ve set the bar quite low. You need basic knowledge of installing programs on your computer and using them. You should have some idea of
how a solderless breadboard works
and it is advisable that you have a multimeter and know how to measure voltage with it. And you shouldn’t be afraid of using Google to research questions that aren’t explicitly answered here.
What does a microcontroller actually do?
This is a loaded question. For the sake of understanding I’ll take this down to the most simple explanation:
A microcontroller takes some type of input
It makes a decision based on the software you have written
The outputs are changed based on the decision in step 2.
A microcontroller does what you program it to do. It does so quickly, and reliably.
How does it work?
For this tutorial series I will be discussing digital logic. That is to say that all input and output pins will be judged based on a voltage of zero, or 5V. This produces our digital 1’s and 0’s, with 5 volts as a one, and zero volts as a zero.
So if you want to light up an LED just wire up the circuit to a pin, make that pin an output, and set it to a logic high (5 volts). If you want to add a button, connect it to a pin that is set as an input and program the chip to measure the voltage level of that pin. It really is that easy, once you learn how to write the correct commands so that the chip understands your wishes.
A look at he chip itself
I’ve decided to use an ATmega168 microcontroller. It’s a powerful chip but it’s no harder to start using than its younger brethren. It will leave plenty of room for you to grow into your projects, while remaining affordable (less than $4.50). Here’s a diagram of it:
This is often called the pinout as it shows what each of the 28 pins on the chip actually does. All of these pins have multiple functions and that’s why there’s long lines of text next to each, except for five which only have one name. These are the pins having do with voltage and ground (VCC, GND, AVCC, AREF, AGND), an important issue with microcontrollers.
Integrated circuits need a steady voltage source. This means as part of our project we’ll need to build a voltage regulator. This is an easy thing to do on a breadboard, and you should be able to get your hands on the parts locally. It is also worth noting that there is a semi-circular dimple on the top of the chip. This is something you’ll find in the plastic case of these dual-inline-package chips an it’s used to make sure you don’t plug it in backwards.
Take a look at the pinout once again and look for the pins whose names start with PD. You should see eight of them total, labeled PD0 through PD 7. This is a fantastic example of the 8-bit nature of these chips. PD stands for Port D, one of the input and output register.
Everything in these chips centers around 8-bits.
That’s a sequence of eight 1’s or zeros in different combination. If you want to turn on or off specific features, you change one or more bits in a 8-bit register. Every time you want to change one pin you must address all eight in the register. We’ll learn much more about this but not until the third part of the series.
Programming
The ATmega168 is a programmable microcontroller. But better yet, it’s reprogrammable. In fact, when you’re working on a project you’ll most likely reprogram it several times an hour.
This chip has a size limit of 16 kilobytes of programming space. In these modern times of 64 gigabyte iPods 16 kilobytes might sound minuscule. But in reality that’s 16 kilobytes of machine code. You can do a lot with that… trust me.
You do need some type of hardware to get the code onto these chips. Usually this comes in the form of an AVR programmer. In the second part of this tutorial we’ll look at several different programming options, then build and program a test circuit.
Do Your Homework
To get ready for the rest of this tutorial series I need you to gather some tools. You must have some type of computer, be it a Linux box, Mac, or Windows PC. This will run software that takes our code, compiles it into something the microcontroller can use, and then tells a programmer how to write it to our chip.
The compiler
We’re eventually going to be writing our own code for the AVR, which uses the RISC architecture. But we’re doing this on a computer with x86 architecture. The tool necessary to accomplish this is called a
cross-compiler
. This is quite possibly the best reason to choose AVR for development, there’s an excellent tool chain available that can easily be installed on multiple platforms.
Mac users: Install
CrossPack
Windows users: Install
WinAVR
Linux users: Debian and Ubuntu users should install the GCC-AVR package which includes the entire toolchain. Others may want to look at the
AVR-libc toolchain page
for help compiling the packages.
This is not the only option. Many Windows users swear by
Atmel’s free AVR Studio software
. This is the only time I’ll reference it as I don’t have a Windows machine and have never tried that package.
Programming software
Our software-of-choice to run the hardware programmer is called AVRdude. If you installed one of the toolchains above you should already have this program. Go to a terminal window or the command prompt and type the following to make sure:
avrdude -h
This will show the help screen. If you get an error, you should check to make sure you properly installed the toolchain in the previous step,
or go download AVRdude yourself
.
What the future holds
That wraps up the introductory installment of this series.
Part 2
:
In the next installment of this series we’ll take a look at several pieces of hardware that you can use to program an AVR microcontroller. I’ve written a
hello world
program and will walk you through building the circuit on a breadboard, connecting the chip to a programmer, and using AVRdude to write this simple firmware to the device. I don’t want to get you too excited, but this does involve a flashing LED.
Part 3
:
A pre-compiled HEX file was used to program the AVR microcontroller in Part 2 of the series. In this portion we’ll look at the C language source code that made up that firmware. I’ll also talk in-depth about the peripherals available on the chip and detail how to use them. We’ll finish up by adding functionality to the original program, recompile it, and reprogram the chip with the upgraded version.
Part 4
:
Now that you’ve acquired AVR programming skills I’ll show you how to start building cool stuff with them.

Something to bridge the gap between Microcontrollers and Integrated Electronics? Something along the lines of 32 bit MCU meets linux DIY? Maybe it’s just me, but this is the next step I would like to take… Beyond pushing digital lines, mapping analog readings, and having LED’s blink next to a nokia LCD.",

"content": "@beaglebreath –Ethernet is pretty easy, but I suspect what you want is a tutorial on implementing an IP stack on one or more embedded systems, and then figuring out how to communicate with it from within a program on your PC.Many versions of popular microcontrollers now come with ethernet interfaces, requiring a module, and source for a complete ethernet stack with limited IP functionality.Ethernet isn’t that big of a conceptual leap from asynchronous serial – there’s another layer or two of housekeeping, but that’s all. You’ll need to understand buffering, but everything else is done for you.If you want to control them through software, you locate an IP stack or IP library for whatever language you want to use.In the end, you’re still just sending text and data back and forth like before – it’s just that you have to specify a few more parameters needed by the IP protocol.Running TCPIP does chew up resources on a microcontroller, so it was common to throw a pre-programmed ethernet “coprocessor” on it and just bit/byte bang as you would with a UART.However, built-in interfaces roughly equivalent to a uart started showing up a decade ago. For example, this old-timer is still around:http://www.microcontroller.com/news/dallas_8051_ethernet.aspAs you guys keep moving up the rungs of design complexity, it gets pretty common to simply design a full linux system into whatever you’re building. Once you can run gcc on it, you can run anything!",

In Jr. College I took a basic electronics cours but when it came time to reading resistor rings I lost interest because I am color blind. The instructor suggested I drop the class and I did. That was 26 years ago and I am convinced that todays electronics has a lot to learn without having to be able to distinquish colors. Besides, all I need to do is ask a friend “hey, what color is this”.Looking forward to the next lesson. Thank you HAD.",

"content": "there is nothing wrong with using an arduino in some situations. I agree with most arduino bashers when you rage over leaving a full board or a basicstamp with a breadboard in a project. But I have no problem basing a project on an arduino, especially if i embed the chip on a custom board.I’ve programmed Freescale HC12’s in assembly for a class and I used ATtiny 85’s in AVR Studio C for my senior project. I never used an Atmega, but i would say based on the ATtinys that they would be extremely powerful if you knew how to control everyting.The problem is interfacing with things like LCD’s or extracting the exact serial staments you want from an GPS NMEA output. If your code needs to be extremly fast and efficient then go with AVR studio or even assembly. If your just building simple things for fun then i say go with arduino. I’m working on a GPS system to hunt for Geocaches. I’m going to build a custom board that will interface the Atmega328/GPS/LCD. The arduino already has prebuilt libraries for lcd and gps and makes it funner to build things like this. I I got most of the coding done in a couple hours while watching tv.btw its worth mentioning for part 2 that the AVRISP mkii programmers don’t work with Windows 7(not easily) the drivers don’t work. There is a work around but it took me several hours,lots of searching and many many installs/uninstalls of AVRGCC and AVRstudio",

[Johncon] wrote this fantastic instructible showing us how to
make an RGB LED headband
. This should come in really handy the next time we find ourselves needing one… it happens. He picked up this little RGB LED strip while on a business trip to Shanghai. He had to reverse engineer the chip that controls each pair, but once that was done there wasn’t much left to do. He’s using a picaxe microcontroller since he had some lying around and, as he points out, they require very little external hardware.
He says he’s going to be ordering more of this LED strip soon and is willing to make a group buy if anyone is interested.

Halloween Props: Pumpkin In Standby-mode

Evil Mad Scientist Laboratories is preparing for Halloween with
this standby-mode pumpkin
. Inside there’s an LED plugging a hole that is drilled just to the skin of the gourd-like vegetable. It fades in and out similar to a sleeping Mac, using what we think is a vastly over-powered circuit based on an ATtiny2313 (1k of programming space for this?). But we still like the idea and we’d enjoy seeing it scaled up to a full LED matrix.
We’ve come to expect pumpkin hacks from EMSL and they don’t disappoint. Last year was
a mechanized version
, and the year before
an LED schematic symbol
. So what about your creation? With about one week left, take a look around and see if you can’t create something as wonderful as
the Pie of Sauron
.

FM Bug Using Salvaged SMD Parts

"fm",
"nokia",

"transmitter"

If you’re a soldering ninja this
FM transmitter bug
is for you. It’s quite similar to
the one we looked at yesterday
, but this uses 100% salvaged parts. Two phones donated components; a Nokia 3210 for its voltage-controlled oscillator and a Nokia 1611 for the rest of the parts. The bad news is that mobile technology like cellphones use some of the smallest surface mount packages known to man. That’s where the soldering skill come into play. The good news is that if you’ve been scavenging for discarded phones in order
to reuse their LCD screens
you already have these parts on hand.
[Thanks George]

You record at low quality for days or weeks – when there’s actually something to hear – and then spit it out at huge data rates with time stamps – equivalent to wifi at 50Mbs – in a single burst, which is repeated later just in case.Sadly, german uboats had prior art.Later, I thought I had again done something special – use a vox switch to record when something could be heard, buffer the data, and just keep up a quiet little low bandwidth stream of encrypted data that could be turned back into speech… running all the time. If there was no data to decode, you just sent random data until something new popped up. It doesn’t take much to bury the signal into the background noise.Sadly, and inevitably, there was french prior art, and it turned out to be a common technique of the ELF submarine crowd, including american subs.Technology has moved on, and now there are serial interface low power ram chips far advanced over our little 8 MB storage. And 8 pin processors that can do a/d, d/a, compression and power management with time to spare.“It’s so easy an arduino user could do it!”If you want to see these techniques in action, complete with remote api built into the hardware, just look at any smart phone built after 2009.It’s nothing short of amazing! :)",

Forget flashlights, and leave those burning lasers at home, [Ben Krasnow] built a
search light using a 1000W xenon arc lamp
. That box you see on the side of the trash-can housing countains a starting circuit that shoots 30 kilovolts through the xenon lamp to get it started but it is separate from the power supply. [Ben]
started experimenting with the lamp back in April
but recently finished the project by using the inverter from an arc welder to get the 50 amps at 20 volts needed when the lamp is on.
The insert on the left of the image above is an outdoor picture of the beam. You can make out a tree at the bottom. Take a look at the video after the break for a full walk-through of the circuitry and some test footage of the finished product.

It won’t be well collimated, but he can build a pretty decent pixel writer using this and some galvos, or do moving signs using bulk r/c servos and stick on mirrors.If he wants to be seriously old school, a bunch of 12″ x 12′ mirror tiles with a bit of black hi-temp paint can be assembled like a ferris wheel and will allow him to project “moving pictures” on the sky.The mechanics of this aren’t complex, but the demo I saw as a kid was a guy who used plywood, expoxy and duct tape to fit big mirror tiles on the hub with tire of a large truck rear-end and then drive it with a motor. He had to screw around to get the beam right, and the tiles may have been smaller (it was a long time ago) but I thought they were large.Voila! Stick figure animation on low clouds. I think he used a small vietnam era search light, YMMV.",

To handle a bulb like that without extreme caution and leather protection, let alone full face mask is crazy. They take a tiny bump and bam, ‘glass grenade’. Having the front of that housing unprotected is just poor. A bug shitting on the bulb while hot would cause it to fail dramatically.The oil from a fingerprint is enough opacity on the bulb surface to cause the bulb to fail. There’s a reason they ship in explosion-proof containers.Granted; I worked with the 5-15k watt versions, so 1000 seems quite small, but still EXTREMELY dangerous.OTHERWISE: Great project!",

This isn’t the first time you have made this minor and very common mistake.”I always laugh at statements like this. Some people can’t handle abstraction, and try to make up for it by being pedantic. If Jason wants to be precise, he needs to discuss this at the lowest level that makes sense.Voltage is electric potential energy per unit charge, which we call volts but mean joules per coulomb. He pretends that electric potential is a better way to deal with the topic, but this must be distinguished from electric potential energy by noting that the “potential” is a “per-unit-charge” quantity.Saying that “Voltage is a difference in potential ACROSS something” shows that Jason is OK with using SHORTHAND for describing the work required to move a charge. Voltage is not the difference in potential, but the amount of work that has to be… well, Jason doesn’t have time to deal with charge and Coulomb’s Law, because Jason chose to use the layman’s description of what is going on.And yet he’s bent out of shape because the author said the voltage goes through a circuit, which is not a mistake, but rather a SHORTHAND term used by many people who learned electronics by connecting things together to make a circuit.Jason, if the guy’s description of the process were wrong, it’s perfectly OK to correct him. But in this context, you’re being silly. It’s like getting in his face about light being wave-like in nature when you know it’s all particles.This guy is trying to become ray charles one tiny arc discharge at a time, but no one imagines for a minute that his internal understanding of electricity is wrong.If you want to do him a favor, buy him a white cane and some dark glasses.",

Very cool.But it made my eyes itch. There is a general trend here, btw. At 8, having just read a book about Edison, I tried to make a filament bulb using a clear glass vitamin jar and some wire. I tried to create a vacuum by sucking the air out with my mouth. The spirit of Darwin was always hovering nearby, as he still does.I did in fact manage to get a lightbulb filamemnt made by putting cotton thread in a toaster (I wasn’t allowed to use the stove) and when I plugged it into the wall, my home made lightbulb glowed very brightly.“I’m so cool!” I thought. (and still do, Sadly)Seconds later the filament crumbled, the wires shorted and the wire blew up. Since I was holding the wire in my bare hand, it burned a lovely “U” into my thumb. The black residue around the electrical outlet was impressive, but after I regained my senses, I hid everything, put an ice cube on my thumb and went out to play.Later that day I talked a 12 year old neighbor girl into renting me part of her basement bedroom for my biology lab… because my mom wouldn’t let me have one (I was 8 and too young for a lab, she said.) and I really needed one for my work.I was 8. To this day, I have no idea what my work was going to be, other than involving white lab coats and a hare-brained scheme to generate oxygen from algae. Really, I didn’t have anything other than a vague idea that I would keep my rabbits and chemistry stuff in her bedroom. We agreed that the rent would equal my lunch money, and the deal was struck.She helped me drag a small table into her room, and promptly got undressed… to uh, help me. I think she had other experiments in mind, but I was very determined to conduct my own research, which didn’t require naked girls, as far as I was concerned. I remember telling her that she would have to get a lab coat if she ws going to help.I was far more concerned about going and getting my 3 test tubes, my batteries and a fish pump (it made bubbles in the test tubes) for immediate use. I had everything installed and bubbling away when her parents came home. She ran out of the room; the next day she came to my house and said I could have my stuff back because her parents didn’t want a lab in their basement.I think I dodged a bullet.",

Marijuana is a Schedule 1 drug, ie illegal on a Federal level. States can have more restrictive laws than Federal laws but they cannot be less strict. Having said that Xenon arc lamps put out a spectrum very similar to natural daylight, so given the high concentration of light you would sunburn your plants.

I just turned off my light and drove away, hey I was working.

No, I wanted to be the guy who built the spacecraft and designed the equipment they used.You know how kids who discover sex too early or get molested by some adult are messed up for life? I’m that kid, except that a drunk jazz musician taught me to read and write when I was four. A very bad idea, in retrospect.You try going to kindergarten when you’re reading third grade books while everyone else is learning to color the letter “N”. I’m not even that smart – I’m more or less the intellectual equivalent of that chain-smoking baby in the phillipines. Instead of cigarettes, someone gave me books and I became a junky who had to know more.I wish my stories were bullshit. I have a strong compulsion to try and do everything one can do in life, and time is running out for me.@pizza dude-Ha! I have a similar story. I had auxillary brights for a while on an old car. I don’t know what the fascination with bright lights were – it seemed like all my friends were melting paint on garage doors at the time.Anyway, my stupid setup was a row of four 28 volt military aircraft landing lights (swiped from a dump) connected to batteries in my trunk – basically a rallye setup, and driven by a contactor. One day I was coming home and some arse had parked in the middle of the street with his brights on.So I turned on mine, thinking I’d show the jerk how rude it was. He turned his off. I turned mine off. He turned on his police lights and indicated that I should park. After much furious bowing, scraping and general kissing of his nether regions, I was let off with a warning.I just disconnected them. I never had the giant flood light, but I know how nice it is to make it noon at ten-thirty pm when you can’t find a place.I wish I had that for the back roads here, where there is no moon and no stars for most of the year, and they turn off street lights to save money.@Dave mcDave –I wonder if it was the same post-sputnik book about the kids who built an oxygen tent for a chimp with pneumonia using algae. That book should have had an FDA warning on it – along with Tom Swift books – because it convinced seven year old me that even kids could do anything they had to if they just studied and were willing to make mistakes.The childhood biology lab experience was directly influenced by that book and “the germ hunters”, and about three boxes of circa 1966 space program propaganda for children. Soon I had a dozen mayonnaise jars with pond scum (I couldn’t distinguish algae from any other green slime) and little aquarium tubes all connected together and supposedly generating oxygen. I had no idea what I was doing – in essence, my science was cargo cult science… but I was in fact “doing”.@barry99705Yeah, I’m guessing she’s probably fat, old and likely has great-grandchildren and a big collection of problems I couldn’t solve. But yes, I’d like to have seen her in her 20’s. You know, I don’t even know why I suddenly remembered the lab story. Oh yeah, the exploding light bulb trick.How the hell I made it to 9 is beyond me. Thank god I didn’t read about arc lights until I was 10. Maybe the TSA should profile 8 year olds with a copy of the “Golden Book of Chemistry” and access to college dumpsters. You want examples?I remember finding a 30.06 rifle bullet and thinking I should be able to convert it to a small solid rocket if I could ignite it. My dad confiscated it when I asked him if he could help me drill a hole in the bottom of it so I could put a fuse in. This was pretty typical for me.A little girl I knew was given a pocket watch by her grandfather, and she proudly informed me that it had 18 rubies in it.I knew that ruby was used to build lasers, so I immediately started offering her almost everything I owned in trade for the watch so that I could start building my laser. I knew nothing about lasers other than they were science, and I needed one.Ruby rod vs tiny chips of ruby used as bearings? Access to strobe lights? Bah! Mere details. Thank God I had nothing of interest to her. So, I was pretty active in science, but it wasn’t really science. Just an 8 year old with a fetish for technology that kept getting worse for a few decades until I realized it was a fetish.But I suppose chris won’t like these stories much either… :)",

Panaplex In A Jar

Check out this
home made panaplex display
. Panaplex displays are closely related to nixie tubes, but instead of layering individual numbers and lighting them separately, it uses pieces to build the numbers like a digital display. [Lindsay] managed to make one at home, using a jam jar as the vacuum tube. Argon as the gas in the tube gives it a pleasant purple color. We really think the end result is fantastic, you can see some build pictures and a run through of the numbers on the site. Unfortunately there aren’t any videos of the display in action.

Then the tube was placed in a holder. Later, this became direct pin insertion. However, the technique is available to mere mortals.May I suggest the work of this gentleman?http://paillard.claude.free.fr/Now, back to chinese counterfeits, the bane of anyone doing high tech mechanical work! I applaud the chinese economy – where else can you find a usable sheet metal brake in a kit for $20? However, as you move up the food chain, counterfeits – and usually really weak counterfeits at that – are the rule rather than the exception.This is even more true in metals – if you think finding a specific type of glass is hard, try obtaining any part or blank made of expensive metal alloy with specific properties.7 out of 10 times, we will receive something that looks and weighs the same, but when you try to use/machine/melt it, you will discover that it was made from recycled bicycle rims and a bit of rusty magnesium. Finding rusty magnesium is like finding 2% dog’s milk, but chinese factory reps are very clever.From electrolytic caps filled with tomato soup base to aircraft engine crankshafts made of fairly good pot metal, we’ll be paying the price for some decades into the future. Caveat Emptor.PS – I don’t hate the chinese; It’s like having a school teacher turned stripper from marseilles for a sister in-law – as long as you know what’s in the fine print, it livens up the holidays.",

Tiny FM Transmitter Bugs Rooms

Lucid Science delves into spy-tech once again with this
tiny FM transmitter
. Their post demonstrates a bit larger version than seen above, using a 9-volt battery and protoboard sized to match which makes for easier soldering. The design uses a microphone, two transistors, enameled wire for the coil, as well as various resistors, capacitors, and a potentiometer. What you end up with is an amazingly clear audio signal that can be picked up with a normal FM radio.
This would make a great project to do with the kids. You can talk about circuit design, practice soldering, and when finished they’ve got an almost miraculous toy to play with. Just be careful what you say around the house, the room might be bugged!

Bravo!The frequency drift can be reduced a lot by putting the RF circuit behind a screen, using an additional RF buffer stage, regulating the power supply and compensating for temperature by choosing the right parts. But that would make the circuit much bigger and harder to build by a newbie.About 20 years ago I managed to build a FM transmitter using a CB xtal on the main oscillator then tuning the RF amp to the 4th harmonic (27MHz*4=108MHz). You can’t get more than a few KHz of deviation when modulating a xtal on the fundamental freq, but its 4th harmonic had enough juice to be heard loud and clear from a commercial FM receiver. Definitely not HiFi though it was more than enough for bugging.",

All gathering dust, and generally with an airplane around somewhere.And now my stuff sits around and gathers dust and loses calibration.

He was 14.But I could see he ahd the fire.My imagination ALWAYS outstripped my skill level, but I guess that’s the way it should be; As soon as I had working neon blinkers I wanted to build a computer; After building a couple of computers I wanted to work on AI; after I could do SMT I wanted to ship masks to be fabbed; and so on through a whole range of technologies. It’s a great life for a hacker, even if my brain could use a couple of defrag passes and a bit of cleanup.But even putting serial numbers on white blood cells doesn’t come close to beating the experience of connecting all those parts up based on faith that the schematic meant something, and then hearing my own transmitter on the radio.",

Multiple Core Propeller Speeds Up Display Addressing

Th
If you ever wondered what an eight-core Propeller processor can do for you, [Tom] found one answer. He’s using the
multiple cores to individually address serial displays
. He has six display modules, and each of them incorporate six 8×8 LED modules. This makes for a total of 2304 LEDs, and since they’re addressed by cascading serial data, that means 2304 bytes pushed to the display. You’re going to suffer from quite a bit of slow-down if you choose that communication method.
This is where multiple-cores come in handy. Instead of cascading data between the six modules, he assigned a different core to each. Now he can concurrently address the six displays, reducing his serial data from 2304 bits per frame down to 384 bits per frame. As you can see in the video after the break, updating the display six times as fast as before yields fantastic results.
Now what if you’re using
a processor that has forty of these multi-core Propeller chips
?
This does make us wonder, can’t the same thing be done on a single-core processor? An eight-bit device takes one cycle to set all eight bits on a single port. So why not just connect the six serial connections on six bits of the same port? Weigh in with your thoughts in the comments.

That makes the display-routine itself nice and snappy, and moves the task of interleaving the bytes to the routine that writes the display memory, which gets used a lot less. An AVR should be able to push that many bits just fine, for my own LED-display (http://spritesmods.com/?art=ledmatrix) I actually use grayscales, which means that the AVR needs to send the data at about ten times as fast as with just b/w, so driving 6 displays with it should be doable just fine.",

Sigh. But it’s worth it to get access to sexy technology toys.I hope I don’t come off as a “it’s been done” hater, when I’m really just a crank, or becoming one, anyway. There used to be guys who would hang around hot rod garages and do a valve job or some welding for free, and who had a lot to say. Ever see the movie “world’s fastest indian”? I’m that guy, but in electronics system design instead of motorcycle racing.These projects teach us a lot. I suggest that he look at prior work in display driving. If there’s anything I’ve learned of value, it’s that some dumb bastard already did what you want to do, and probably wrote about it.I’m serious – there is almost nothing you’ll think of that hasn’t been done, redone, reworked, redesigned and abandoned repeatedly in the last 30 years, if not 300 years.This used to drive me nuts. I once wrote some software that was (I thought) decades ahead of the literature and industry practices. I was proud of this, and the patent was going to be paid for by someone else. Then I discovered that the technique had been used and documented in the mid 1970s, and a long time after that, I discovered that some guy had done it in the late 1960’s – and done it in fortran.Now I believe that any solvable problem is solvable – if enough cumulative IQ is pointed at it. If you could see how fast and how far internet surveillance has come since 2005, you’d be amazed. Most of this is thanks to salaried guys at search engines, because they have the time to chew on it. It’s the same for this guy’s software drivers.HAD represents an enormous think-tank of experience and knowledge. Some of it is probably BS or useless, but in general, many hands and brains can improve the tech and solve complex problems. I think our posts should be an equal mix of “Have you considered?”, “I saw this done” and attaboys. I just wish the “it’s been done” guys would leave more details about the HOW, which is most useful for everyone else.I urge experimenters to try and constantly evolve their projects… and to leave behind breadcrumbs for others to follow.",

UV EPROM Eraser In A Toolbox

[Devon Croy] belongs to a hackerspace that works hard to keep hardware from going to the landfill. He found they were in possession of over a hundred Erasable Programmable Read Only Memory chips (EPROM). Not to be confused with EEPROM, which are electronically erasable, these EPROM chips require a strong source of UV light to blank the old data before they can be written again.
Instead of buying a tool to erase two or three chips at a time
he built his own bulk EPROM eraser
from an old metal toolbox. He used parts from a fluorescent black light and acquired a new bulb that generates light in the UVC spectrum, the band which works as an eraser for the chips. After bolting the parts into the case he added a spring-loaded timer knob and a safety switch that kills the power when the case is opened, similar to
the UV exposure box
we looked at yesterday.
Of course, if you don’t need a bulk eraser you could shop some garage sales for
a UV pacifier cleaner which can also erase EPROM chips
.

Most people who know how to work on this stuff probably earn more per hour than to waste their time UV-ing / inserting / removing. But of course it’s his choice what he does with his time.",

This looks like just the thing!I cannot tell you how hard it is to truck my little mistakes down to the dentist to clear them using a goodly dose of X-rays, and then have to wait for hours while they bake in the oven to anneal the damage caused by the X-rays before I can put them in the programmer and have another go.Am I the only one that misses having to provide -12vdc or +25vdc to a part in order to program it? Why on earth would you want to throw away perfectly good EPROMS when the only alternatives are nearly free eeproms that are drop in replacements? :)I know the feeling, but it might be time to move on. The days of blow and go are past us – and I don’t miss them very much. However, kudos to the guys out there making it fly. More power to you.I hope that someone will post an article showing us how to wind core memory and access it with an arduino! 8 x 8 should be easy enough – you could store simple passwords in a way that would resist gamma rays.And if we could obtain enough mercury, we could build a mercury delay line memory device. And vacuum tubes! So much technology slated for the landfill waits for resurrection. Please, show us how to dig those old DTL and RTL logic cards out of landfills and connect them up.Nostalgia – it ain’t what it used to be!",

Why store it in the cloud when you could have
a 90 Terabyte hard drive
(
translated
) array in your house? The drives are mostly Western Digital Caviar Green EARS 2TB models which are known for energy efficiency and quiet operation. It’s a little unclear as to whether this is using one or two motherboards, but the drives are connected using PCI RAID5 and RAID5+0 controller cards. There’s a total of 40 cooling fans built into the case, half on the bottom and the rest on the top. They move air up through the case, with plans to add a dust filter in the future. Heck, with that type of air movement you could throw on a standard furnace filter. Apparently it is quiet enough to talk in “almost a whisper” while next to the plywood monolith. But we’re a bit skeptical of that claim.
It’s not quite as fancy looking as
the 67 TB storage from last year
… but it does look pretty easy to build at home.

But little fans are cheap and plentiful, so people use them.Also, there’s a sort of area rule about how much air you can shovel through a tiny opening, and tiny openings are easier to find than large ones in most applications.It’s kinda like electrical wiring – before we realized that lots of outlets and big standardized circuits were the way to go, house wiring would often have just two little fuses that were expected to cover everything… or very ornate fuse boxes that had a bunch of 5 and 10 amp screw in style or cartridge fuses.In general, “that’s the way we’ve always done it” has a lot of benefits, even if “it’s the best way” isn’t one.",

He could have just used two box fans, (for redundancy :), and had better air-flow with less noise and MUCH lower cost.So yeah, it’s cute, and I hate to bag on something that somebody obviously spent a lot of time on, (definite hacker cred for the plywood! :), but there’s definitely some glaring deficiencies in this design.

From a corrosion standpoint, maybe not so hot, but when you have big fans and decent grounding (exposed wire grounding to catch stray electrons), it’s OK.ZFS: Don’t get me started. Yes, it’s cool. You do NOT want a giant single volume, and if you don’t have a backup plan (and @90TB, you don’t) you’re just asking to get reamed. You will lose data by doing this, but go ahead, find out why all by yourself. Infinite Logical Volumes smell nice and all, but after getting nailed repeatedly by loss of 30 TB databases, I’ll leave it to the ZFS fan boys. Putting all your eggs in one basket is a bad idea, no matter how cool the ZFS feature set is.WD Green: If it says made in china, you have a >50% chance of death by mechanical failure. Look for OEM drives from any place but china. There’s a reason they’re so cheap – almost no Q/C at all. The most recent 1TB Green I purchased failed SMART for excessive write errors within 60 minutes of uptime. Seagate seems to be back to old tricks again, as well.Did you know that drive manufacturers turning out product in China bid your HDs out to the lowest bidders in batches of a few thousand? And the bids are awarded on price and price alone. Not a chance in hell for Deming’s methods when there is no accountability. If a drive manufacturer (OEM) screws someone, a new shell company forms to “do a better job”, at least until the check clears.That aside – if you’re a RAID believer, please buy your raid drives from different manufacturers and different vendors.

I think you are confused by the difference between a raid group (in zfs terminology: top-level vdev) and a data volume (zpool). For example you certainly don’t want one large N-drive raidz (raid5) vdev because if 2 of the N drives are lost you lose data, but in zfs one zpool is made of multiple vdevs. For example to optimize my X4500 servers, I configured them with one 46-drive data zpool composed of three 15-drive raidz2 vdevs plus one spare drive.",

And in general, until you get to RAID-10 and transactional backups, you’re not even close to protected. LVM is a grand idea, but it has real world consequences. When you move to LVM environments, your ability to recover useful data from partial drive recoveries drops to zero. But maybe all the anecdotal evidence I hear about from the IT guys at investment houses and research labs is FUD.I’ll just say this: A lot of people have mistaken impressive conceptual promises for real world guarantees, and been bitten hard. Wanna know where all those scanned mortgage documents a certain BOA constrictor can no longer find went after the merger and data migration? I’ll give you a hint: When you don’t test your ability to restore data, you don’t actually HAVE the ability to restore data. As they say, quod erat demonstrandum.@guy who wanted a mufflerWhat you want is a baffle, not a muffle. You can probably do it by trial and error. Your goal is to just silence the noise of the fans. The bad news is that doing this “right” requires a lot of calculation. However, you can fake it by leaving an open area at the end of the box, and then building 3 movable dividers that take up 60-75% of the height of the box and stagger them.If you simply move them back and forth, and try it, you can empirically get to the right positions.I wish I could draw a sketch for you, but just google “audio baffle” and you’ll get the idea. All you need to do is make it hard for the sound waves from the fans to get out by setting up a standing wave to cancel out the frequencies of the fans. You could calculate this by using an audio spectrum analyzer to figure out the primary signals (and maybe a harmonic or two), then do a little math to come up with the wavelengths, and so forth.This is too much work for the backyard experimenter, so just move the baffles around until it gets quieter. If you’re not comfortable with using 60-75% partitions, you can also drill small holes in the baffles and make them full height. Make sure the holes don’t line up. The hole method isn’t great for temperature reduction, because it destroys any hope for laminar flow.You can pack way more baffles in if you limit the redirection of the air flow angle to ~16% at a time – and if you have the room to use curves, you can do a great job killing noise. This is all the rage in the door-less bathroom designs found in public places (the ones where they do it right), but… acoustic engineering is a big topic.I’ve seen plexiglass panels used in baffles with good success if they are mounted in a frame using a flexible weatherstrip or gasket… perfect for angry screaming monkeys, or small children who are crashing from a sugar high.Finally, you can absorb some high frequency noise (from drives, for example) by using rubber or flex compounds to provide mechanical isolation. It makes a huge difference! If you cover the baffles with acoustic foam or even neoprene (the material they use in wet suits), you can pretty much treat the unit as being silent.Good luck!",

It’s that time again, time to take on the machine with the Hackerspace,
Crash Space
(and
part two
)! The team of Californians set out and successfully turned the front of their building into a musical instrument, similar to [David Byrne’s]
Playing the Building
. When a pedestrian walks by they set off distance sensors, which in turn actuate mallets that strike particular objects to produce a tone. We were pleasantly surprised at how interactive the installation was, even if it didn’t sound that great. But will it be enough to beat out the previous two teams? And how will it do up against Artisans Asylum’s
not what you’re thinking
Breakfast Machine next time?

[Vassilis Papanikolaou] took a good thing and made it better with some
design upgrades to this AVR based signal generator
. We looked at
version 1.0 of this tool
back in 2006 and since then it saw
an upgrade to 2.0
. But [Vassilis] wanted to take things one step further, with a compact single-sided PCB. What you see above is the beautiful result of his work; a professionally made board that is compact, uses through-hole components, and has zero wire jumpers.
If you want to build one for yourself there’s a great parts list as well as board artwork and schematic. The system uses an ATmega16 so you’ll need a way to program one. There’s also just a bit of firmware tweaking to remap the control buttons to match the updated hardware layout.

Building A UV Exposure Box

"pcb",
"resist",

] |
There are two methods of using etchant resist when making circuit boards. We use the toner transfer method that requires ironing on laser toner to the copper, but you can also use chemical resist that reacts to ultraviolet light. [Bogdan] decided to start doing more of the latter so
he built a UV exposure box
to make the process easier.
It is possible to use flourescent light bulbs
for this, but he decided to use UV LEDs,
a method we’ve also seen before
. But there’s always room to innovate, and [Bogdan] built-in a couple of nice features that are new to us. Because the UV light can be bad for your eyes, he included a set of red visible-light LEDs on the bottom half of the box that are used to align two layers of exposure mask when making double-sided boards. There’s also a switch that automatically shuts off the UV light when the box is opened. And as the coup-de-grace, he added
a programmable timer to regulate the exposure
, using his newly created box when etching the PCB for it.

UV blacklights are far cheaper for the power you’re getting for this application, even if they don’t sound as cool (which is the only reason anyone wants to do LEDs)the bigger problem, which i’ve seen in almost all exposure boxes, is the lack of collimation. the light coming out of most exposure boxes here is not well collimated at all–the LEDs spew light out at a crapton of angles. what does that mean? suppose you have a ray of light going at 45 degrees from the normal, which is very reasonable (at these distances, it’s probably even worse). your photoresist thickness is 1-2mil, so you easily get 1-2 mil undercutting on both sides of a traces. 8 mil becomes 4 mil–good luck with that. and it’s probably worse than that in real life. . .really, just build one of these:http://www.thinktink.com/stack/volumes/voliii/equipment/uvlamp/uvlamp.htmthese guys have been around forever, and are pretty darn legit.",

I might check that in the future. What would you suggest as a collimator?As for your suggestion of 18″ tubes. It defies my needs and purpose: small compact box. Of course it is cheaper to make with tubes. you just can’t make it so small(ok, maybe you could if you could source 2W UV tubes, which i couldn’t).@nfs maybe you should read the data sheet of the LM317 better. Short answer: it can handle 1.5A. and it is stable at such current if you use it right. The whole box consumes about 1.2A. That three amp diode is the next larger thing i had after 1n4007.UV light is below 400nm. The leds i use have a peak wavelength at 405nm. It’s safe to say half of the energy they put out is below 405(almost all UV) and half is above, which is visible.",

No. But I suspect that your suggested phrase “The cherry on the top” fell out of favor circa 1960, having been used for roughly 80 years.Languages are living things; therefore, y’all aint got no reason to be hatin on the boy’s grammar, ma petite ami. :)And yeah, it’s like that.",

If you want that kind of precise definition, you’ll need to use a dead language, like latin. And even latin continues to morph – not as quickly as living languages, but there have been shifts over the last 200 years as we lose the context those languages were used in.Even programming languages shift.Look at BASIC.Things change along with society.Skipping words like Freedom or Liberty, let’s look at the word “punk”. Do you think anybody who called themselves a punk circa 1977 knew that 40 years earlier it generally meant “young gay prostitute”? Ya wanna see some action? Indeed.Or the french word for hospital, which is pretty much like the anglo word, except that the S fell off a truck some centuries ago and was replaced by a circonflex that was hanging around. It used to mean a place where you could go to die and receive a bit of random attention, if you had money, but now it means… well, maybe that’s not the best example.I speak french, but generally in the context of picking up girls and arguing politics. I cannot offer definitive proof, but I have heard this phrase used to describe something cool in this exact manner by french people.I mean, at some point you have to allow that the phrase “Spanking the monkey” has nothing to do with monkeys or spanking.",

[Patman2700] has a nice scope for his paintball gun that uses a red dot instead of cross-hairs. The problem is that he kept forgetting to turn it off which ended up running the batteries down frequently. His solution to the problem was to get rid of the toggle switch used to turn it on and replace it will
a home-made momentary push button switch
. Now he presses the switch to aim and doesn’t waste juice when he’s running around, trying not to get pelted with paint.
Since this is used outside he wanted it to be water-tight. The switch is built using materials we’ve seen in
previous diy switches
; adhesive-backed copper sheets for conductors, foam to keep them separated until pressed, and plastic as a support. Copper is applied to the plastic base, with a ring of foam separating the base from the second layer of copper. When squeezed, the two layers of copper come in contact to complete the circuit. To make it work a bit better [Patman2700] added a dab of solder in the center of the bottom copper layer so there is less distance between conductors, and used extra foam to build up a bump in the center of the assembly for a better ‘button’ feel. The whole thing is encased in shrink-wrap with the seams sealed with super glue to keep moisture at bay.

Your hamster lives to good life, with food delivery and a maid service that cleans up after him. [DanF] helped to brighten up this hamster’s life even more by improving its exercise equipment and giving it a small night-light as well. This project
adds a low RPM alternator to the hamster wheel
.
The first part of the process was to reduce energy lost to friction by fitting the wheel with a bearing. From there a ring of permanent magnets was added which will pass by a stationary coil and induce a current. It works, but unfortunately there’s not enough power generated to charge a battery. That means the light is only on when the hamster is running. But maybe you can figure out a way to use a super-capacitor like we saw in
that exercise bike hack
.
One nice finishing touch to the setup is a bicycle computer to track how much time was sent on the wheel, and the distance traveled.
[Thanks Dizzy]

New Dynamic Duo, Arduino And Eclipse

There are a lot of solutions to
programing an Arduino
: the default avr-g++, Studio, etc. But [Sandeep] let us know about using one of the more powerful IDEs out there,
Eclipse
, to do the same. We’ve already outlined why
Eclipse is a great IDE
but now the fact that you can use it in your MCU based projects adds to its usefulness and already
large feature list
. However, don’t be turned off by [Sandeep’s] tutorial. While it is aimed at people who are completely new to setting up an IDE and working with an AVR, the tips certainly can benefit even the most experienced hacker.

Sure, I was thrilled when I learned about $2 AVRs being 50x more capable, but those BASIC Stamps are what got me started.Arduinos are even cheaper and more powerful than a BASIC Stamop, so its a pretty cool situation.I certainly think more people should embrace the AVR within, once they’ve gotten used to the Arduino, but that doesn’t mean the Arduino isn’t a great platform!And honestly, anyone that doesn’t see the value of a quick and easy development and learning tool is just an idiot.",

Plantenna: The Plant Antenna

The back story behind [Mike] experimenting with plants as
AM radio transmission
antennas
antennae
is rather interesting and worth the short read. But for those who just want the facts, [Mike] took an ATMega324,
modified the PWM
output into a sinusoidal AM signal (using a simple form of
RLC circuitry
), and connected the circuit to a plant
no plants were harmed in the making of this project
. The results? Well we’re not ones who would spoil the surprise, you’ll have to see for yourself in the video after the jump.

He didn’t even provide a scale other than what he perceived as an improvement to show the actual increase in signal reception. I’m willing to bet my coffee maker (and I love my coffee maker) that the plant has a next to negligible effect on the transmission and that the bulk of the transmission is being performed by the wires the alligator clips are attached to and the device itself.Up next peopletennas, pie platetennas, and pennytennas.All of those were things I used when I was 8 to bring in CTV a little clearer on the farm since my bedroom didn’t have access to the outside antenna.

RLC is tunned and thus it is selective though, where it will attenuate some frequencies more than others, and that is what he displays on the plotted graphs. But saying it amplifies is no sense. Note these are pure theoretical graphs, simulated and not taking account parasistic impedance nor many other important aspects by which an actual frequency response of his circuit will be different to what he plots out.2) More interestingly, he has the transmitter and receiver very close each other, much closer than 1 wave length, which means he is capacitively coupling transmitter and receiver. So this is not radio transmission, as the antenna doesn’t work as such but as part of a coupled capacitor. He should move receiver significantly further away at this frequency to start talking about radio.",

I can really only tell you what worked and what didn’t. I don’t have any RF instruments so I can’t quantify any of the results above. All I can say is that with that alligator clip connected to the plant, reception was improved qualitatively. With the clip disconnected (but the wire STILL attached to the circuit), reception was not quite as good. But again, it was a small difference. With regard to the RLC circuit, no, it doesn’t amplify the output power. However, it does amplify the voltage at the antenna. That’s the resonant nature of this RLC circuit. Granted, not all RLC circuits are resonant (underdamped), but this one was designed to be.Anyway, I hope you’ve still found something here interesting/useful! My apologies if I’m wasting your time. If you’re really curious about this circuit, build it and tell me what happens. Thanks!-Mike",

I never found any proof of the phenomena. The only odd result is that it consistently produced an audible signal when a car pulled into my driveway. Though I never figured out exactly why, I believe it’s just science, not the supernatural.BTW, you can get a much better connection to a plant by driving a conductor into the soil, like a large nail. Make sure the soil is moist (doesn’t have to be saturated) and properly fertilized (the chemicals salts enhance conductivity); both of which should be the case anyway. I’ve used this to connect ionizer modules to houseplants, in order to train cats not to treat them as salads. A few harmless static zaps and they never mess with that plant again.",

It may have been deleted, you might have only sent it to Caleb (in which case, the rest of HAD team can’t possibly feature something they don’t have!) or otherwise.

There is some significant difference between this Plant Antenna article by [Mike] and your flickr stream. Mostly being, Plantenna by [Mike] was a very well written thought out article that was clear, detailed, had pictures, and other support. On the contrary, you simply posted a series of pictures, which while /we/ at HAD may understand what is going on, others might not.In short, for anyone who wishes to be featured on had, take the following to note.http://hackaday.com/2009/09/19/how-to-make-your-project-an-internet-sensation/Jakob GriffithHAD Team",

Using A Cellphone LCD As Auxiliary Linux Display

[Neil] is
driving this Siemens A60 LCD using a parallel port
on his Linux box. He likes this module because it has an integrated LED back-light, controller IC, and the pads are large enough for a human to solder. He notes that the screen runs on 2.9V, which matches the forward voltage of the LEDs used as back-lights. This means it is possible to use one f the LEDs as a shunt to drop incoming voltage down to a safe level for the controller. In fact, that’s what he did. The data lines are connected to the parallel port along with some current limiting resistors. The LEDs are connected with resistor calculated for maximum brightness, with the output from the LED used as the source voltage for the LCD controller chip.Whether you want to use one of these screens with a PC or something else, the code that [Neil] worked out should provide the information necessary to do so.
The
Nokia cellphone LCD post
inspired [Neil] to send in a tip about this project. If you’ve got well documented hacks that you’re just sitting on why not
let us know about them
?

"content": "@bogden: Yes, I realize that VGA in analog but converting to that, or DVI, from the digital interface used by the base panel is needed in order to interface the panel with a traditional PC (which I, personally, would find useful).I, also, realize that the actual interface used is likely to be highly custom. On the other hand, these panels are manufactured by the same companies that make full size monitors and general purpose panels. It’s possible that the engineers that designed them stuck with a common format like LVDS or TTL for simplicity’s sake.If that were true, then it should be possible to get an off-the-shelf VGA-to-LVDS/TTL boards to work with it. The problem is, of course, that without any documentation, the only way to figure out if this is the case would be to reverse engineer the interface. Unfortunately, I lack those electrical engineering skills and keep hoping to find that someone might have blazed those trails already.",

The interface is also ‘smart’. The cpu ‘talks’ to the display and it talks back. Some tipical conversation might be: goto that part of the screen, select a regtangle x by y pixels.

(what you are describing sounds, very much, like how the industrial touchscreen “smart displays” work in automated systems here at my company). However, I don’t think that would work for a smart phone, like the iPhone, where the display has to be able to do many of the dynamic things that a real PC display does. Also, because, by their nature, LCD/Plasma/etc. screens don’t “refresh” in the same way old CRTs did, I would tend to expect that standard LCD panel interface formats, like LVDS, would already be taking advantage of any of these kinds of optimizations that are possible.Of course, these are all assumption and could, very well, be wrong. It is, however, why I think it’s reasonable to hope to see someone hack these displays into usability.",

[Jeri Ellsworth] continues her experiments with electroluminescence, this time
she’s making EL ink
. The ink she’s looking for is Zinc Sulfate in a solution. The process she chose is to re-dope some glow powder so that it can be excited by the field around an AC current. In her video (embedded after the break) she talks about the chemical properties she’s after by detailing a cubic lattice of zinc and sulfur atoms with an added copper atom (adding that atom is a process called doping).
The quick and dirty synopsis of the experiment starts by washing the glow powder with dish soap to acquire zinc sulfide crystals. Then she combined copper sulfate and zinc shavings from the inside of a modern penny to yield copper metal and zinc sulfate suspended in solution. That was mixed with the zinc sulfide from the glow powder washing and doped with a little more copper sulfate. The excess liquid is poured off, the test tube is capped with glass frit, and the whole thing hits the kiln to start the reaction. The result glows when excited by alternating current, but could have been improved by adding chlorine atoms into the mix.
We’re excited every time we see one of [Jeri’s] new chemistry hacks. We’d love to see more so if you’ve come across interesting chemistry experiments during your Internet travels,
please let us know about them
. Just make sure you have some idea of what you’re doing when working with chemicals… safety first.

Even then, it’s not gonna look like the fusion reactor that seems to appear in american superhero movies.OK.I want to point out that the glow is a point contact glow – it is visible through the gem, but you won’t be creating a super-hero laser effect without a lot of work. On the plus side, it’s often green. Any impurites in the silicon will create different colors, but you already knew that.The jewel is called moissanite, and it is rapidly going out of fashion for a variety of reasons. JC Penny in the US was a major retailer, but I don’t know who else sold/sells this stuff. The company is going down the tubes as far as I know.Moissanite is basically the same old circa 1900 silicon carbide material used for radios, and it essentially was the ancestor of diodes and silicon circuits in general. I think an american found the glow, but a russian physicist published a paper or two on it. Olav? Olev? Something like that.You basically grip the material in an alligator clip or any kind of metallic holder (I used the earring base, which was crimped on but had holes underneath) and then using a cat’s whisker/needle/whatever, apply the bias current to it.The physics are almost identical to ordinary LEDs, as the material is the same. Current limiting is a good idea.You can crush up moissanite and build your own low quality LEDs by creating the correct shape, inserting it into the plastic leaving a gap for the electrons and then sealing it. Vacuum pumps help, but not necessary.They typically use a metal substrate and then apply a very small particle of silicon carbide or carborundum to save material. The gems are the same thing in large purified form.The plastics used in old LEDs are recoverable through temp controlled melting, btw. Any transparent plastic should be usable for light devices.Finally, if you watch the currents, you can have multiple anodes/cathodes on a single gem. It isn’t easy to do.I blame this experiment on absinthe. It’s way cooler to use jewelry. Good luck!",

It took us a while to stop drooling long enough to write about this amazing machining project. [Denis MO]
made a single-lens reflex camera from scratch
. The banner image above is not the finished product, but just one step in the production chain. [Denis] has been thinking about doing this project for 25 years and finally took the plunge. From the start, the only parts he planned on NOT making himself were the screws, ball bearings, shutter, curtain fabric, and interchangeable lenses. Everything else is his own creation based off of his own design. Spend some time looking over his project. There’s plenty of information and images of both the machining process, and the drawings he mocked up in the design process. We’ve also included a pic of the finished camera and the contact sheet from his test roll of film after the break.
[Thanks Javi]

Given the relatively simple design of a basic plate camera, the only *real* hurdle to complete open-source camera hardware is the (extremely non-trivial) matter of producing a lens more complicated than a simple meniscus.But if someone wants to develop the reprap version of an optical thin-film coating machine, capable of consistent and repeatable multilayer lens coating, that’d be a good start. :)",

(And the lens too but grinding lenses is a whole different field and I’d tend to exclude that from this discussion.)Anyway it’s more than I could do and as I said I give the work done plenty of credit, I just put some reservations on it because as I said I know using a lathe is part of basic curriculum for mechanics.Oh and incidentally, a $3 throwaway camera manages to advance film fine, there’s no big need to have the parts between the shots accurate to withing a millionths of a millimeter, it just should not overlap.What’s more important is having the back where the film sits completely parallel to the lensmount at exactly the right distance, without play but still allowing the film to move between shots, and the lensmount being completely flat, now that’s more a challenge than simply advancing the film I would say, and there very high accuracy counts, and you can’t lathe it either.",

Propeller Platform Prototyping Board Gets An Upgrade

[Nick] over at Gadget Gangster has a new version of his prototyping hardware for Propeller microcontrollers, called
the Propeller Platform USB
. A little more than a year ago
we looked at the last version
which was larger, used a DIP processor, and came unassembled. The new version does come assembled because of the migration to surface mount components (which may take some of the fun out of it if you just love soldering kits). This not only reduces the board footprint, but makes room for more goodies. As the name implies, there’s now a mini-USB socket with a USB to UART bridge, a microSD card slot as been added, and the onboard EEPROM has been doubled. This is a nice hardware upgrade but the price has been upgraded by $25 as well. No worries, it’s open source so you can roll your own if you have the parts on hand.

If you consider the cost of adding these features to the Prop by using off-the-shelf modules not to mention the hassle of setting up the software to access them this could save a lot of time for prop-based projects.If anyone has any interest in pursuing this concept please get in touch – I can arrange production but don’t have time for any of the design work right now!",

Hacking TVs In 1954

This gem was
published in Mechanix Illustrated
magazine in may of 1954. AT that time, a remote control was the stuff of science fiction. This article shows the modern man how to modify his television to include a fancy button to stop all noise. This button, affectionately labelled the “SHADDAP” was marketed as a way to relieve the pain of long winded commercials. Basically, it cut the connection to the speaker, nothing super fancy. Is that an altoids tin as an enclosure?

Non acronym version of the title
: send and receive text messages via cell phone communication towers using an Arduino or other microcontroller. “We’ve been doing that for years!” you cry,
well yes
, technically. But [Fincham] lays it outs simply;
commercial offerings
are expensive and finding a
cell phone that uses RS232
now a days is getting difficult, so a new way of doing the same old is necessary. The good news is
USB GSM modems
are readily available, cheap, and only require a few interface pins to get them talking with an Arduino. In fact, the image above is all you need.

Here’s a little trick that will make the driver routine cleaner for “hackish” use.Out of the box, the modem registeres as a GPRS609 USB Modem, and only the supplied driver will work. With this driver, the thing will register as a modem in windoze, not as a generic com port. The generic PL2303 driver will not work.The PL2303 USB-serial chip in this thing has an option to use an external serial eeprom to hold id information for the USB part. This id is what connects the chip to the right driver.Now, looking at the card, there is a little 8 pin IC (SO8 SMD chip, eeprom from Atmel I think) By removing this chip (apply extra solder to all 8 legs, pinch with two cheep soldering irons, and lift of the board) the PL2303 no longer has OEM ID, and will work with the generic PL2303 driver.The modem will now register on your computer as a generic serial port, and you can experiment with all the AT commands in a terminal window.The PL2303 generic driver can be downloaded fromhttp://www.prolific.com.tw/eng/downloads.asp?ID=31Enjoy..PS: Now, for the adventourous, if you lift the PL2303 TX, and RX pins from the circuit board, and bring wires to the pins and pads externally, you have a combined TTL generic USB to Serial module, and a SMS/modem in one small package..Best regards from NorwaySpangen",

[Rafael] built a system that uses radio frequency for communications. The code he was using with the inexpensive receiver/transmitter pairs already had some error correction but from time to time an entire message would be missed by the receiver. He set out to
make these RF communications more robust
.
A little more than a year ago we looked at
using these same transmitters with an Arduino
. [Rafael] has a similar setup but since they are unidirectional he chose to use two pairs for bidirectional communication (each operating at a different frequency to avoid interference). On one end, a computer transmits data to the Arduino which is in a remote location. His confirmation protocol relies on a randomly generated message identifier. The computer will continually transmit the same message. The Arduino continually receives these messages, comparing them with the last successfully received message. If they match, it is considered a successful data transfer and the Arduino transmits a confirmation back to the computer which then starts transmitting the next message.
This isn’t an application-specific protocol. For demonstration purposes [Rafael] built a quick home automation setup that uses it to operate a house lamp.

Far more efficient would be to hash or checksum the data and transmit that sequentially.Or better still would be to add some forward error correction (Viterbi would be a good choice) to the packet so the listener has a chance to correct any errors locally before requesting retransmission.",

"content": "@xorpunk“no open source UART RF transmitters?”I guess it’s because a lot of people see it as trivial, and a lot of people see it as voodoo, and the vast majority are content to use “established off the shelf standard units” from various places. For the newbies, here’s the 411:The UART is easy – whether built into the system or implemented in software – especially if you’re just sending data in packets, or fixed length bursts. Robustness is something else altogether – you need error detection, at least, and maybe correction [pain in the ass, generally] and maybe bidirectional communications. All a uart does is take a digital word or byte and pass the status of the 1s or 0s sequentially to the output pin, or take the input and stick it into a word or byte for later use. We generally do this at a fixed rate using a timer, but there are other methods using clock signals and so forth.Bidirectional full-duplex communications is a pain to implement without hardware help, but it makes an excellent introduction to the joy of realtime programming. Bidirectional half-duplex communications is less of a pain, but when radio or other uncertain transmission media are added to the mix, well, you tend to get a little crazy.Anyway, to get back on topic, RF transmission of data boils down to picking a modulation and demodulation method, piping it to and from the radio and getting on with the job. Therian actually raises a good point, even if his grasp of the subject appears hampered… It can be worth trying to minimize your usage of an RF channel for a lot of reasons.If you just want to bang data around, I suggest buying a couple of the cheap prebuilt modules. On the other hand, if you feel that hacking is the way to go, just find any circuit for an FM or AM transmitter and receiver pair. These can be built with one or two transistors if you don’t mind the awful side effects of drift. Given a wide enough bandwidth, it can work at low data rates (300 baud, anyone? 110? 75? ) and at a single digit baud rate, you can get pretty lax with your circuits.Most people go for crystal or resonator controlled transmitters to avoid the pain. So you can build a bad ass low frequency FM or AM transmitter with a crystal, some logic gates and a few components – especially if you like really fat channels and lots of harmonics. The schematic is pretty simple – one quad NAND gate chip in the cmos family will get you all the way to the FM broadcast range and beyond. The 555 is usable, but isn’t a good design choice outside of audio ranges.So if you want to modulate it, you can just gate it on and off. This isn’t very sophisticated. We really want FSK or quadrature to get anything done, so now you have to be able to shift the frequency rather than turn it on or off. To do this, we need a little more gating and maybe another oscillator.I can’t be bothered to do this*, so it’s easier to just program the mcu to pump out the modulation frequency directly by using a timer in the MCU. Then you can connect this to the aforementioned oscillator circuit, and now you have all kinds of options for modulation.(*actually, this is all historical.)But to give a wink at therian, you now have to worry about reducing the bandwidth and removing all those harmonics that cause interference. This means putting filters on the circuit so that what gets to the antenna isn’t all over the place. Think of it as focusing a light to a narrow beam.The receive side is simply the reverse process.You don’t need radio to play with this code, it can be quite instructive to try and test your ideas using a microphone and speaker connected to input and output pins.Figuring out how to get usable audio from a microphone into a single input pin on a microprocessor constitutes an excellent and complete introductory course on signal processing, as you learn that PWM is magic!",

With 2400 LEGO bricks and a lot of patience, [Will Gorman]
built a LEGO 3D printer
. It’s similar to a RepRap or a Makerbot, but instead of extruding plastic, it uses pre-extruded building blocks (aka LEGO bricks). The grey wall extending far above the unit itself is a feed magazine which holds the raw material. A Java application takes an MLCad file and translates it into building instructions for the printer. Those instructions are then sent to the device via USB. See it happen after the break.
Now this just needs to be combined with
the LEGO sorting machine
for an inexhaustible supply of bricks.

Data Plotting For The Visually Impaired

"arduino",
"cluster",

"visually impaired",

This setup helps to represent data in a meaningful way to for visually impaired people. It uses a combination of physical objects to represent data clusters, and audio feedback when manipulating those objects. In the video after the break you’ll see that the cubes can orient themselves to represent data clusters. The table top acts as a graphing field, with a textured border as a reference for the user. A camera mounted below the clear surface allows image processing software to calculate the locations for the cubes. Each cube is motorized and contains an Arduino and ZigBee module, listening for positioning information from the computer that is doing the video processing. Once in position, the user can move the cubes, with modulated noise as a measure of how near they are to the heart of each data cluster.
The team plans to conduct further study on the usefulness of this interactive data object. We certainly see potential for hacking as this uses off-the-shelf components that are both inexpensive, and easy to find. It certainly reminds us of
a multitouch display with added physical tokens

Halloween Props: Dancing Spider
|
Mike Szczys
|
[
"home hacks"

[
"12f683",
"Halloween props",
"mosfet",
"pic"
] |
[Isaac] grabbed the motor from an old printer and used it to
make a spider run up and down
the wall for Halloween. A PIC 12F683 uses a MOSFET to drive the motor. The program loop has a little bit of dramatic flare to it, raising the arachnid with a bit of a jerky motion to give it some life, then wait for a time before quietly lowering the spider (hopefully onto an unsuspecting party-goer). The driver board is set up for two motors, making it easy to reuse in future projects. This is quite effective, and the only addition we might suggest is to add a couple of red LEDs as some glowing eyes.
Take a look at the finished product after the break.

Cards you should crank
These greeting cards
must be the product of a mechanical engineer run amok. They come with a crank and are designed to entertain with their simple, yet elegant movements. [Thanks Phil]
Magnetic card stripe reader
[JP] built an Arduino based
magnetic card reader
. It uses off-the-shelf parts but if you don’t mind buying the components this will get you up and running in no time. If you want more info there’s also this
Teensy based version
.
Homemade Airsoft sentry gun
This sentry gun
has an amazingly fast firing rate that can continue for quite a while, thanks to the big flashlight housing that is holds a lot of ammo. [Thanks David]
Scanner easter egg
The engineers over at HP had a little fun
building an easter egg into this scanner
. If you know what you’re doing you can get it to play the Ode to Joy. It needs to join
the old-hardware band
from our Links post earlier in the month. [Thanks Googfan]

Not exactly consistent ROF but you’d never really notice since it has huge volume. The explosions are definitely happening because he’s getting jams in the barrel, which clogs and lets the pressure build up in his gun, and the lowest strength parts goes flying. Looks like the top to his hopper. Of course, this also sends BBs everywhere. Because it’s a constant air feed system, you also need the top to keep it from randomly sending BBs into the local area.",

Master Clock System Uses All Logic, No Microcontrollers

"clock hacks"

[
"atomic",
"clock",
"digital logic",
"master"
] |
What you see above is a master clock. It is the center of a system that can run an unlimited number of slave clocks, keeping them on-time thanks to its ability to synchronize with an atomic clock. [Brett Oliver]
put together the project
back in 2005 using digital logic chips, and no programmable microcontrollers. This includes everything from the binary decoders that drive the 7-segment displays, to the radio transceiver board that gathers the atomic clock data, to the various dividers that output 1 second, 2 second, 30 second, 1 minute, 1 hour, and 24 hour signal pulses. It’s a well document and fascinating read if you’re interested in
digital logic clocks

Quite a coincidence. This got me thinking though, I have a pair of logic-based LED clocks my dad built back in the 70s (one for local time, one for GMT). Maybe I could put a once-a-minute FET output on one of them somehow.

To me the wiring of the components with thousands of wires is a dying skill. The clock should look as good open as it does when closed. Yes it could be built with a few PICs ( I have used one in my Calendar clock) but it just would not look the same.It is a 1 off and non commercial and was posted as a collection of ideas. I am sure no one will build the whole clock but may find some of the ideas useful.The clock and slaves are very reliable and keep in sync with the DCF77 signal from Germany perfectly.Long live Comic Sans.",

Gesture Controlled Robotic Hand

"hand"
] |
Inspired by the control system for the AMP suits in the movie Avatar, [Feelpavan] built this
gesture controlled robotic hand
. So far there is functionality for the wrists to rotate and bend, as well as for the fingers to flex (but not individually). This is accomplished by three servo motors on the hand assembly. The instructions for the hand are gathered from your own hand, through the use of an accelerometer and an Arduino that he built himself. Check it out after the break.

Here’s a strange one.
This fighting game
uses a video game interface to instruct modern-age gladiators on how to bring the pain. The costumed fighters cannot see anything other than a set of lights in their helmets instructing them to move or punch. A camera films them and overlays the footage on a digital background along with simulated blood and a health bar for each. NES controllers are used to instruct them, and switches inside the costumes register the pummeling they receive and deduct health accordingly. This wouldn’t be any good without a demonstration, which we’ve embedded after the break.

Sadly, this pocket
mp3
wav player
doesn’t come close to the capabilities of even an iPod generation 1
yet
, but you have to give [Owen] props for making it in less than 24 hours. The system consists of a Propeller MCU (cleverly wired to be swappable with “shields” similar to Arduino systems), SD card for song storage, and an LM386 for audio. While the setup is a little dull, and only plays through songs non stop with no controls whatsoever, it certainly is a good start in the right direction for a cheap and simple portable
music player
. Of course some planned changes are in the works, include an accelerometer (gesture based controls?), etched PCB, docking station, and
a case
. We’re surprised there is no form of screen planned, considering Owen appears to have a rather good handle on
touch interfaces
; perhaps he’s waiting for revision 3.

We’re rather surprised at how popular it has become to build your own motorcycle computer. [Mario Mauerer] tipped us off about
his shiny motorcycle computer
(
translated
) for his Yamaha XTZ 750. It uses an ATmega644 microcontroller to pull a variety of data together and display it on this white LED backlit display. He connected a flow meter to the fuel line to monitor gas consumption. Oil temperature is captured by inserting a brass tube (containing the sensor) through a hole in the oil cap and soldering it in place. Water temperature is gathered by measuring the external temperature of one of the cooling lines. [Mario] uses a rotary encode with a click function as the control interface device, and a battery backed real time clock keeps time.
A quick look at the PCBs tells the tale of good circuit design. But we do wonder about catching the reflection of the sun in that shiny bezel.

I’m Swedish and when I play around with LCDs or other stuff that requires me to output text I usually stick to English. Why? Because it’s often a bit of a pain in the ass to add support for our extended alphabet. In Sweden we have three additional characters after “z”, namely “åäö” or “ÅÄÖ” in caps.These characters appear “out of order” in the ASCII table so you have to add logic to handle them separately. By sticking to English you can get away with being a bit lazy :)",

"content": "It’s an interesting exercise, but the values generated & displayed aren’t worth much beyond a way to start a conversation…1)The “fuel flow” measurement will be, at best, an educated guesstimate. Consumer-level flow-metering hardware used in this manner will be less accurate than a the tank-level gauge. If the meter-spec is actually good enough for the task, it still needs to have its’ flow-measuring accuracy calibrated and verified after it’s been installed in the system that’s being monitored. No calibration means that you’ve made a somewhat unreliable fuel tank level indicator.PS: Good flow meters measure mass, not volume. :)2)The accepted ways for measuring oil temp require that the probe be immersed in the oil that’s down in the sump. The described method is measuring the temp of the air/oil mist that’s being created by the spinning clutch backet. It’s influenced to some degree by the oil’s heat downstairs, but the biggest influencing factor in the area you’re measuring so-called “oil temp” is the air going past the outside of the engine as it cools the clutch-side of the crankcase. You’ll get a temperature indication, but what it means is dubious.Nice try, but the wrong approach. Fwiw, simply inserting the probe deeper into the engine from the oil-fill hole won’t help either.3)There’s a similar issue with measuring the temp of an external coolant line. A better way to measure the coolant’s REAL temp would be to have the temp sensor/pickup attached to the radiator’s lower reservoir, and insulating it so the only temp seen by it is the coolant temp within, not the atmosphere blasting past it on the other side.",

"content": "Thanks for your points, but:1.) I calibrated the flow meter directly in the bike and achieve a accuracy of 5% at the gas station, which is pretty much enough for the desired task, as the original motorbike hasn`t any fuelgauge at all.A much bigger problem is the fact that the fuel travels back and forth in the fuel lines with every revolution of the engine because the fuelpump works with the vacuum generated by the engine (inlet suction), i guess it will be better if i mount the flowmeter between pump and carb and not before the pump…gotta do that next season.2.) The engine got a dry sump lubrication and guess where the sensor is – right – in the oil tank. So this is the best place to measure the oil temperature, because the engine is ready to do something when all the 4.5 liters of oil are heated up – which is exactly what the sensor tells me. (it takes about 15km/10mi for the oil to get up to ~60°-70° celcius)3.)Yes, the water temp sensor isn`t optimally placed. But when i built it i didn`t have the time to drill a hole into a radiator screw.But the Water temp isnt`t of very much interest; The bike has its own water temperature gauge.Greets from SwitzerlandMario",

Computer Aided Cake Decoration
|

[
"Misc Hacks"

[
"cake",
"candy",
"decorate",
"frosting",
"spirograph"
] |
This contraption lets you
decorate your cake at the push of a button
. It’s a stretch to call it computer aided as this is purely a mechanical monster, but we still enjoy the apparatus and see its CNC potential (we’re still waiting for that
pizza printer
to hit the market too). An icing syringe has been modified with a flexible hose on the business end. As constant pressure is applied to the plunger, the nozzle oscillates while the cake rotates. What results is a spirograph drawing on the top of your dessert. But the fun doesn’t stop there. Another push of the button and you get shiny silver orb candies joining in the party.
What, no video? Aw! If you know where to find a clip,
let us know
and we’ll update this post.
[Thanks Mowcius]

Brightest Day, Darkest Night, Charge It With Arduino’s Light

To userp the Green Lantern oath is a sacrilege. But calm your rage as you take in this
Green Lantern battery and ring project
. [Jon] built the power battery portion out of LEGO, but inside you’ll find an added bonus. An Arduino uses a set of LEDs and an RFID reader to bring the object alive. A matching ring contains the RFID tag that activates the lights when held up to the lantern’s lens. You can see this used to charge the power ring (and join in by saying the oath) in the video after the break.
Want to build something like this but don’t have an RFID reader? This would be easy to pull off by adding a magnet to the ring and a hall effect sensor in the lantern. Maybe this will make you rethink your Halloween costume this year.

The Polyplasmic Archophone

] |
The
polyplasmic archophone
is a fresh approach to high voltage “
arc music
“. They are using an Arduino clone to convert signals for the ignition coils. It is still unfinished, but the effect is decent. In the end it will have 2 tiers of voice coils for a total of 13. They are using different materials for the antenna so they can get different colors of sparks. You can see a video of it after the break and we must say the effect is quite nice. Change the lighting on that video and we could imagine this being the set to a [Joules Verne] movie.

A more modern implementation is shown here:http://www.youtube.com/watch?v=rasp88nbsRwAlso, You don’t need multiple coils to get polyphony:http://www.youtube.com/watch?v=UGD64MjRTfAWanna build one? Search for 555 and flyback.Then whip out your arduino and PWM the output of the 555. Two things:1. These suck at BASS. So for a full-on cataclysmic sound machine, buy some earth shakers (big mag coil with audio in designed to rumble theatres) and add some bass.2. Don’t touch the arc. It’s like ghost busters. I have a small custom tattoo courtesy of high frequency modulated HV, and it just reached out 12 inches and “modified me” by what seemed to me to be remote excavation of bare skin. I wasn’t being careful enough.But the biggest problem is that you can touch this stuff and say “hey, it tickles!”… not realizing that the muscles and nerves underneath the skin are being prepped for destruction. It can take a long time to notice the damage.On that note:500KV makes for some serious arc lengths. Check this out – it’s a giant mechanical switch. Notice how long it takes for the switch to open the circuit!http://www.youtube.com/v/PXiOQCRiSp0&rel=1&fs=1&showsearch=0&showinfo=1&iv_load_policy=1Posted at7:42 amon Oct 16th, 2010 by bilbao bob",

Adafruit industries is doing their part to help the hacker community with their latest addition,
a job board
. It just went live today so there aren’t many jobs posted, but we expect that to change in the immediate future. you can also post your services offered there, if you’re looking for work. We really appreciate when companies support the hacker community, so we tip our hats to you Adafruit.

When you start to think about the cellphone waste our society produces it can be quite daunting. How many cell phones have you had in recent years? Now multiply that by five billion cellphone subscribers. [Anthony Goh] and [Neil Mendoza] found something to do with a very minuscule portion of those left-overs; building
interactive birds out of the old parts
. You’ll have to check out their accomplishments in the video after the break as the image above doesn’t do them justice. Interactivity for the exhibit is provided by an Arduino, which communicates with one working phone via a serial connection. The phone can still make and receive calls, and controls parts from other, less functional cellphones. They can call each other, or receive calls from the audience.
Yes, there is art in garbage. But there’s also a lot of hacks waiting to happen. Take a look at the
Nokia cellphone LCD
feature and then start scavenging.

C Sharp Development 101 – Part 2: Toolbox Controls

In this tutorial we are going to start finding out more about the toolbox we utilized in the
previous tutorial
. The Controls available in the toolbox are quite extensive and allow users to simplify a variety of everyday tasks such as manually creating and instantiating a textbox on a windows form. At the end of this tutorial you should be comfortable finding Controls in the Visual Studio Toolbox, alter or produce code to link tools together using event handlers and ultimately get a better sense of Visual Studio, it’s layout and how to easily navigate it.
To start we are going to create a new Windows Forms Application project in a new solution that will be called ApplicantRegistration. After the project is created we need to change the name of the form from Form1 to main and change the name on the top of the form to Applicant Registration under text in the Properties tab. Then we can start adding in labels and changing Text and Name Properties for:
First Name (Text: First Name, Name: lblFirstName)
Last Name (Text: Last Name, Name: lblLastName)
Address (Text: Address, Name: lblAddress)
City (Text: City, Name: lblCity)
Zip Code (Text: Zip Code, Name: lblZipCode)
Email Address (Text: Email Address, Name: lblEmail)
Phone Number (Text: Phone Number, Name: lblPhone)
After the labels are completed, we need to add the text-boxes that are going to coincide with the labels. The textboxes are going to have to be altered to make the names of each textbox readable when we do decide to code some guts. The following are the textboxes that must be added to the form and the changes to the name property as well:
First Name (Name: txtFirstName)
Last Name (Name: txtLastName)
Address (Name: txtAddress)
City (Name: txtCity)
Zip Code (Name: txtZipCode)
Email Address (Name: txtEmail)
Phone Number (Name: txtPhone)
After this has been done the result should look like this after moving the labels and text boxes around the form:
We now want to add the button that we are going to utilize to enter the forms data into a storage container. We need to drag the button from the toolbox onto the form and change the Text to “Submit” and the name to btnSubmit. After this is done we can double click on the button which will take us to the code that will be utilized when the user clicks the button. To do this we are going to start out by clearing all of the form data so when the user presses submit the boxes clear and are ready for another entry. To do this our code will look like something along the lines of:
private void btnSubmit_Click(object sender, EventArgs e)
{
txtFirstName.Text = "";
txtLastName.Text = "";
txtAddress.Text = "";
txtCity.Text = "";
txtZipCode.Text = "";
txtEmail.Text = "";
txtPhone.Text = "";
}
After the code for the button is made we want to extend the form to the right and add some controls for birth-date and gender. We will start by making labels for Birthday and Gender respectively. After we have created the two labels we are going to drag three combo boxes onto the form, one for the day, month and year. When renaming objects on forms I tend to shorten what the object is into a minimum of two letters and a maximum of four. The final result would be cbYear, cbMonth and cbDay respectively. We can now drag two radio buttons onto the form and rename the text of one to Male and the other to Female. After these have been positioned we can code the methods to populate the dates and tie the two radio buttons together.
The first item on the agenda will be the two radio buttons. We are going to tie them together so that the two cannot be both checked. To do this we need to check and see if the opposite radio button is checked. We will do this by utilizing the CheckedChanged event handler for both radio buttons and this code:
private void rbMale_CheckedChanged(object sender, EventArgs e)
{
if (rbMale.Checked == true)
rbFemale.Checked = false;
else
rbFemale.Checked = true;
}
private void rbFemale_CheckedChanged(object sender, EventArgs e)
{
if (rbFemale.Checked == true)
rbMale.Checked = false;
else
rbMale.Checked = true;
}
Next we are going to populate the combo boxes we dragged onto the form earlier. To do this we are going to have to check which one is picked and populate the days for that particular month. Leap Years are an advanced function that will be implemented in the next tutorial but will be important to the final build. We are also going to code a for loop to add the years 1900 to 2010 dynamically on the forms startup. We can do both of these by utilizing main_Load and the cbMonth_SelectedValueChanged event handlers. The code will look something like this:
private void main_Load(object sender, EventArgs e)
{
for (int i = 2010; i >= 1900; --i)
cbYear.Items.Add(i);
}
private void cbMonth_SelectedValueChanged(object sender, EventArgs e)
{
cbDay.Items.Clear();
if (cbMonth.Text == "September" || cbMonth.Text == "April" || cbMonth.Text == "June" || cbMonth.Text == "November")
for (int i = 1; i <= 30; ++i)
cbDay.Items.Add(i);
else if (cbMonth.Text == "January" || cbMonth.Text == "March" || cbMonth.Text == "May" || cbMonth.Text == "July" || cbMonth.Text == "August" || cbMonth.Text == "October" || cbMonth.Text == "December")
for (int i = 1; i <= 31; ++i)
cbDay.Items.Add(i);Day.Items.Add(i);
else
for (int i = 1; i <= 28; ++i)
cbDay.Items.Add(i);
}
private void rbMale_CheckedChanged(object sender, EventArgs e)
{
if (rbMale.Checked == true)
rbFemale.Checked = false;
else
rbFemale.Checked = true;
}
The final form should look something along the lines of this now:
The next logical step would be to include code to output this data to a text file or even a database. We will cover this in the next tutorial using both output methods. The first will be a text file as mentioned and the database of choice will be a mySQL database which we will go over installing in the next post. If you are eager you can acquire the program
here
and install it before the next tutorial. We could have used Microsoft’s Access database program but it is not free and the main objective of these tutorials is cheap development.
After this is done we can run the program by pressing F5 and enter in some test data. Once all of the data is entered we can press the submit button and the data – if done correctly – should disappear. If you can’t wait until the next tutorial, here is some reading on
connection strings
and
reading and writing to a text file
to get you up to speed. Until next tutorial, Happy Hacking!

It’s still not the way I would recommend doing it unless you know exactly what you’re doing. If the string in question is a static string AND your “variable” will also be a static string of the same text, the compiler should reference the same location. Therefore, two static strings could be compared using “==” because they would be at the same memory address. Technically you wouldn’t be comparing the data, but the location of the data. Furthermore, this is actually faster than comparing the data itself.",

Vapor Phase Reflow Soldering

Ditch that old toaster oven and move to the next level of surface mount soldering with
this vapor phase reflow method
. [Ing.Büro R.Tschaggelar] put together this apparatus to use
vapor phase reflow
at his bench instead of sending out his smaller projects for assembly. It uses the heating element from an electric tea kettle to boil Galden HT 230 inside of a Pyrex beaker. There’s a copper heat break part way up the beaker to condense the chemical and keep it from escaping. When a populated board is lowered into the heated chamber, the solder paste reflows without the need to stress the components with unnecessary heat. Better than traditional reflow? At this level it’s hard to say, but we do find his method quite interesting.
[Thanks Chris]

Or a laserprinter that uses some copper (or more modern conductive compounds?) ink system.Technology has developed in every other area, and material science has come a long way, there must be a way to make the whole thing convenient, one that actually is not just working in a limited way in some rendered picture on some corporate site under the header ‘one day – maybe’But I guess there too some amateur has to design something and hoping for the techsector to wake up is a hopeless endeavor./semi-rant",

Same for teflon, any good pcb material requires chemical prep to be durable.Most of the conductive inks are silver based. It’s great if you need a flexible thin pcb made of mylar/paper, but it’s limited to things that need antennas or wacky geometry.Conductive toners pose a different problem. Since laser printers use electrostatic charges to distribute the toner to the paper, conduction makes that job a lot harder. Basically, for this to work in conventional process laser printers, the toner would need to be activated during or after the heat step.It’s possible to find conductive fluids that bind to toner after the transfer, but the extra steps make this method more painful than the usual method of printing the conductive part of the PCB onto an intermediate film and then heat transferring it to the pcb material.You still have to etch, but etching is easier than making the toner conductive and then dealing with the fragility of carbon based materials. Finally, none of these processes help if you need holes or cutouts.Even the laser based PCB making processes suck because of alignment and penetration issues – you can do it, but the cost is higher.The next big development will be faux biological creation of pcbs and assembliesd, but you won’t be building radio transmitters or high-speed number crunchers. Well, not very good ones, if the sodium ion transmission techniques can’t be improved upon. And if God hasn’t pulled that trick off in the last 5,000 years, who can?;)",

It doesn’t even bother me.Decorative fictions like the constitution and the “universal declaration of human rights” have pretty much been advertising and fairy tales for the rubes from the beginning. We’re taught that just because a bunch of wealthy aristocrats managed to leverage “higher taxes, unpopular wars and internal conflict” into briefly getting control of the government in 1215, we’re all free.But it’s simply not true. The Magna Carta was about as significant to humanity’s future as was the bible – believers believed, haters hated and everyone else went on about their business.But the magna carta became little more than an inspirational historical fairy tale, just as we see with the constitution, the declaration of independence (damnable british kept getting in the way of George W’s ability to sell whiskey!) and the ten commandments. I figure it’ll take the true believers of the desert religion a little longer to forget what the fuss was all about, but it’ll happen. You see, they believe in something, and that always makes for a bit of a mess for those of us who are part of the established order of things. Give it time. It’ll pass.Anyway, they can surveil away!

This 3D printer manages some pretty fantastic resolution, and these are just
the early results
of [Junior Veloso’s] build. He put together a machine that prints objects in resin that cures in visible light. To print, a thin layer of raw liquid resin self-levels across a printing surface and a DLP-based projector shines light from below, onto the portion to be hardened. The z-axis then pulls that layer up and the next to be printed will become the newest bottom layer. Horizontally the printer yields 1024×768 resolution with a layer thickness as small as 0.01 mm. No wonder he’s turning out this kind of quality.
The model above took 5 hours to print, with eight-second exposure for each layer, and 0.1mm layer thickness. There is lots of good information on his blog, from the
early planning
, to the
finished hardware
so take some time to learn about this fascinating project.
Update:
Thanks to reader [Nave.notnilc] for pointing out that we’ve seen
a chemical 3D printing technique
before.

"content": "This is excellent.My chemistry is weak, but I agree with dude. We need to reverse engineer some of these materials so that we can get the prices down. Those of you who want to research this should examine any of the epoxies, coatings and inks which are advertised as being cationic. You know, as in the majority of modern special adhesives. Look for “Cationic polymerization”.You can buy specific UV cure stuff from everyone, ie LOCTITE 3335/3340 at $300+ for 250 ml or it’s cheaper chinese (causes cancer in bystanders within a 5 mile radius) equivalents. Look into the inks used by large format printers used for outdoor advertising. I think Gerber makes these, but any UV cure ink is a start. Same for UV cure varnishes in the printing industry.Although UV cure reactions are pretty well documented (it’s like 50 years old), hardening by using visible light is a little more difficult.If you can hit a DLP projector with UV, you can use almost anything you can get your hands on.I would predict that the DLP portion should be considered a consumable, the same way we would consider an inkjet printer cartridge.Basically, anything which hardens or undergoes a stable polymer reaction can be used. If you can handle the fumes (nasty, nasty fumes) you can use various super glues. If you can provide vacuum and temperature control, you can use almost any ink.Also, I wouldn’t get hung up on positive processes – at larger sizes and lower resolutions, negative reactions should be possible. In addition, you should carefully look at old school PCB manufacturing processes – remember chemical application of photo-resists? It’s the same process. In practice, it would be fairly slow.If you want to formulate something, a co-initiator might be helpful – you start with something which is light activated, then dope it with other chemicals to alter the reaction to meet your needs. I am not a chemist, but again look for “UV sensitizer” and photo-sensitizers for help.I suspect that bulk 3D printing fluid is already available at any hardware store in the form of some transparent epoxy based paint or varnish…. if you can find something which is not a fast acting self-solvent and can be thinned while retaining these properties.One way around the self-solvent issue is to use a film of material on top of a neutral-transport with higher specific gravity/weight/density than the uncured material. Maybe that’s too much physics, but you can use liquid carriers in certain instances rather than building extensive support structure. YMMV.This calls for rather old-fashioned science of the “I got 99 coatings but pitch ain’t one” type pioneered by the lost souls who worked for old T.A.Edison. Good luck!",

Focus Designs has
a new version of their self-balancing unicycle
for sale. This improves upon
their original design
in several ways. The battery pack has moved to LiFePO4, which is
becoming more common in electric transportation
. There’s also regenerative braking and fall protection which kills the motor when you fall off.
We’ve embedded their marketing video after the break. Our favorite part is the shot seen above: a guy on the unicycle cruising along next to a woman who is running. There’s nothing like sitting on your bum while some else exercises.
At any rate, from what we see in the video they’ve turned out a solid product.

We all love a little bit of multitouch, but we’ve seen so many setups that it is getting a bit less exciting. This one will get your attention with its unique shape. It is a
spherical multitouch
using all open source software. Well, since the poles are unusable, it might just be toroidal, or cylindrical, but it is still impressive. They are using a convex mirror mounted to the upper most point of the frosted sphere to reflect a projector mounted at the bottom of the base. A web cam pointed at that same mirror picks up reflected IR light from a few emitters. You can catch a video of it after the break.

I have a client using it for a training application, and I’m pretty certain that what they’re doing will eventually become mainstream. I thought it was pretty stupid until I tried it.Think of the “Hey, I know kung fu!” scene in the matrix, and replace the hero with an office worker doing something far less glamourous. They think it substantially cuts training time, but knowing if that’s true or not is basically outside my realm. But VR isn’t dead yet.Other than that, I agree.

Window Curtain Moves To Screen Pedestrians

[Niklas Roy] built
a motorized window curtain
to screen out foot traffic in front of his window. When you hear “motorized curtain” you may think that this will move up and down but it doesn’t. Instead, the small curtain move horizontally to cover passersby as they travel down the sidewalk. This is accomplished using a camera in conjunction with some motion sensing software. In the video after the break you can see that the software also anticipates the movement, and ends up doing a good job of keeping the target covered. That’s thanks to the Processing sketch working in conjunction with a rotary encoder on the hardware setup. Details for both are available on the page linked above.
This harkens to other community involvement hacks we’ve seen like the
subway stair piano
, or the
bottle recycling video game
. It’s fun and quirky, which is not too much of a surprise as we saw a glimpse of that when we looked at [Niklas’] public fountain
hydropower generator
.

Pumping Station: One Takes On The Machine

[

"ice cream",
"pumping station: one",
"scion"
] |
Part one
and
Part two
of Hackerspace Pumping Station: One taking on the Scion challenge are up and ready for your viewing pleasure. The team at Pumping Station: One built a Tron themed bicycle that when setup properly, would churn ice cream
that turned your urine neon
in about 6 minutes by using dry ice and ethyl alcohol. Besides sounding not so tasty, and having a multitude of problems along the way, the project turned out the be a success. The question becomes, does it stand up to the last Hackerspace, NYC Resistor, who made a
drink mixing slot machine
? And how will both fair against the up and coming Musical Building by Crash Space?

Here’s
a 2-channel Oscilloscope for your Android phone
. It uses a base module driven by a dsPIC for signal processing. From there, an LMX9838 Bluetooth module broadcasts the data to the phone so that the waveform can be displayed. [Yus] ported some Python code he had been using over to a set of Java and XML files in order to get it working on Android. This was actually the first time he worked with the SDK… we’d say he’s a quick learner. See it in action after the break.

Cadsoft Eagle Migrating To XML

[PT]
posted about an exciting development from Cadsoft
, the migration to XML based parts, schematics, and board layouts. The adoption of this open standard goes hand-in-hand with the
open hardware initiatives
people like [PT] have been pushing for.
Cadsoft Eagle is our go-to schematic and PCB software. We even have a tutorial which guides you through
preparing your files for PCB manufacture
. But the files containing parts libraries, schematics, and board layouts have always been binaries. A transition to XML means a lot of things. They will be easier to edit, and much friendlier for tracking changes using version control systems like SVN, CVS, Mercurial SCM, Git, etc. But immediately on our minds is the accessibility for hacking. Think of how easy XML parsing is in programs like Python. It should be snap to write scripts on a whim that will manipulate the XML files in any way imaginable. This doesn’t discount the value of Eagle, it extends the usability far beyond what any team of engineers at Cadsoft could produce by themselves. And for that, we say Bravo.

No, the advantage of XML is merely that your designs will not become useless far in the future, and you could theoretically create filters to convert to other PCB packages (though you could do this with ULPs anyway).What would be a REAL breakthrough is if someone had created a universal XML standard for schematic+netlist+PCB, and then Eagle and other PCB tools adopted it. Then we’d have reason to celebrate…any PCB file would open in any PCB CAD program? That would rule. And is not what is happening here, yet.",

[Rossum’s] taking
a look at the Nokia LCD screens
that are both plentiful and begging to be bent to your will. For quite some time the
Nokia 6100 screens have been used in a lot hacks
, but he wanted to see what else is out there. He digs into his junk box of cell phones and comes up with a couple to test; the Nokia 6101 and Nokia 2760. The screens use a 3-wire SPI interface, which he sniffs out with a logic analyzer. At power-up the cellphone polls the screen to determine which type of LCD controller is connected. [Rossum] grabs these commands from the logic analyzer and uses it to determine the hardware in use with each screen.
He made himself a nice breakout board which has connectors for several different screens. The firmware he’s using detects when a screen is attached and switches to the applicable protocol for that display. Take a look at the video after the break.

Larson Scanner Hacking

We all love a good larson scanner. They’re so iconic that Evil Mad Scientist Laboratories makes a kit. However, just getting a kit and building it isn’t enough for many of us. How would we make a larson scanner better? Simply by adding more. EMSL shows us how you can
modify their kit in both hardware and code
to chain them together. They detail the modifications very clearly and show some video examples. You can see a three larson scanner chain in action after the break.

Assassin’s Creed Blades Make Us Wince

[TheBserk] made himself a set of
auto-locking and auto-retracting hidden blades
inspired by those in the game Assassin’s Creed. As you can see in the demo (and build guides) after the break, they work really well. We don’t like the idea of sharpened metal ramming its way past our wrists. But it’s not the first time we’ve seen
dangerous arm-mounted hacks
.
Reminiscent of
Taxi Driver
, [TheBserk] uses drawer slides from the local home store for his build. They are cut to length, and modified using springs for the automatic action. There is a lock to keep the blade extended, and a pull-wire to actuate it. Although dangerous, the build is well done. We think someone has mechanical engineering in his future, and possibly a trip to the emergency room.

If you’ve ever designed an embedded system with at least one button you’ve had to deal with button debouncing. This is also know as
contact bounce
, a phenomenon where a button press can be registered as multiple button presses if not handled correctly. One way to take care of this is with a hardware filter built from a resistor-capacitor setup, or by using a couple of NAND gates. We find that [Jack Ganssle] put together the most comprehensive and
approachable look at contact bounce
which you should read through if you want to learn more.
We’re interested in software solutions for debouncing buttons. This seems to be
one of the most common forum questions
but it can be hard to find answers in the form of reliable code examples. Do you have debounce code that you depend on in every application? Are you willing to share it with the world? We’d like to gather as many examples as possible and publish them in one-post-to-rule-them-all.
Send your debounce code to:
debounce@hackaday.com
Here’s some guidelines to follow:
Please only include debounce code.
Get rid of other unrelated functions/etc.
You should send C code.
If you want to also send an assembly code version that’s fine, but it must be supplementary to the C code.
Please comment your code.
This will help others understand and use it. You may be tempted to explain the code in your email but this info is best placed in the code comments
Cite your sources.
If you adapted this code from someone else’s please include a note about that in the code comments.
As an example we’ve included one of our favorite sets of debounce code after the break. Please note how it follows the guidelines listed above.

10/13/2010: Button debounce code by Mike Szczys
based on "danni debounce" code by Peter Dannegger:
http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=189356#189356
This code detects and debounces button presses. It is tailored for use with
AVR microcontrollers but I've adapted it for other architectures easily and
successfully. It can be modified to use all eight bits on the same port
for up to eight buttons.
The interrupt service routine (ISR) at the bottom uses binary counter
variables (ct0 and ct1) to check the buttons once every 10ms until 40ms has
passed. If the button registeres the first and last times it reads it as
a keypress. There is no functionality in this code for detecting a held
button.

"content": "There aren’t really that many correct ways to do software debouncing. The example above is basically what most coders will implement eventually (we’re going to ignore people who hardcode wait loops in their main routine). However, the above example is trading off flexibility and accuracy for the ability to debounce larger numbers of inputs without too much memory use. Since there’s a global 10ms timer and only two possible counts, the debounce timeout can actually range from 10ms to almost 20ms. You have to design for the shortest timeout and accept random longer delays. If you have switches that need longer debouncing, say 50ms max, then since there’s only two counts per switch you must change the interrupt timer to 50ms and accept possible timeouts of 50ms to 100ms. The only way around this is to use a much more fine grained interrupt, say 1ms or less, then implement a separate multi-bit counter for every pin. Obviously using a byte counter is easiest, but if your button count rises 32, 64, or more inputs then the memory impact starts to get significant. Processing all the counters also starts requiring a lot of CPU time, especially if you’re trying to do it once every millisecond. So I would say software debouncing is viable for contacts with short bounce times, and low pin counts…but for larger numbers of inputs, some other type of debouncing method should be explored.",

Buttons are on an interrupt.When you get a port interrupt, you know the button was pressed. Disable interrupts on that port and set an interrupt ‘debounce’ timer. Go about with your business handling the interrupt and executing code. Eventually your debounce timer will break you out of your code (note that you can – and should! – make this a very low priority interrupt if you want real-time performance) and then re-enable port interrupts.

I generally use tactile NO or NC switches with a pullup resistor and check for state change (usually 1->0) on the input pin, either by polling or interrupt. Set a 10ms timer or hardcode a 10ms delay if you can afford it, and go about your business. tact switches will debounce in <1ms so 10ms is even overkill.Or, if you need to be able to hold the button down and not trigger anything until the button is released, simply do a 10ms debounce after a state transition is detected, and then use a while loop or interrupt to react on the opposite state change (release button) and do another debounce.

"content": "“We’re interested in software solutions for debouncing buttons.”Umm why? I’d rather throw a resistor & cap at it while keeping precious processor power dedicated to the actual task. If one is to write a closed loop program, having it sit around timing button states seems like a waist and will severely hinder processing capabilities. I can’t tell you how many times I’ve come across situations where a microcontroller seems to have exhausted it’s processing abilities (this is usually when your average person opts for a more powerful processor) where the entire issue could be remedied with efficient code and/or an additional component or two. One could argue that adding components drives up the cost. To that, I say buying microcontrollers with more horsepower than you actually need to get the job done adds to the price as well. Last I checked, microcontrollers cost a tad more than a small cluster of SMD resistors & caps.I think the issue stems from the decay of modern code due to a lack of programmers who still approaching programming as an art form. These days, it seems that too many programmers/coders are only focused on getting the job done and don’t want to slow down to go low level and really think things through anymore. In fact, many don’t even want to write their own code. They take bits n’ pieces from other sources which, all too often, are scraps found on the net. It has gotten to the point where this approach is not only accepted, but also becoming the norm and the line between programming and script writing is blurred. The big issue comes into play when programmers fail to acknowledge the reality that these scraps of code are sometimes flawed. By the time this is realized, the code has already found its way to many other programs or have even become libraries which accelerate the spread enabling the faulty code to infect new programs like a rampant virus. Just look at the stock market flash crash. Scary stuff. Image when this sort of rubbish makes its way into hardware. In a world facing the steady rise of robotic population whose actions depend on quality programming, this sort of negligence becomes extra scary! When I develop the AI to control the warrior class robots for the robot uprising, I’m writing my code from scratch. :-) All of it!If you’re going to program, then really program. If you’re going to apply this to hardware, then don’t be afraid to actually add some hardware. And, if you’re going to write a long comment on hack-a-day, grammar check is optional. I’m sure I’ll be hearing about it. ;)Now, I’ll say this: I have no formal educations with electronics/programming and I don’t do either as my day job. So, if someone wants to explain why I seems to be the only guy who thinks this way, let me know the reasons and the errors of my way. On the other hand, if you’re with me, can I get a “hell yeah!” or “amen!” or whatever you’re in the mood to exclaim.",

"content": "Specific code isn’t needed, just knowledge of the proper way to debounce a button.Mr. Syczys said, “One way to take care of this is with a hardware filter built from a resistor-capacitor setup” (better known as an RC integrator). But that’s only partially correct. It’s also necessary to convert the analog output of that filter to a digital signal through a Schmitt trigger. MCUs typically have these built-in on their digital inputs, so a separate one isn’t needed; but you *must* acknowledge that it exists if you’re going to emulate a proper debounce circuit in software.So as an example, to emulate a 10ms hardware debounce, just execute the following pseudocode every 1ms:1) If RawInput is pressed, then increment Counter by one, up to a max of ten.2) If RawInput is not pressed, then decrement Counter by one, down to a min of zero.3) If Counter is ten, then set DebouncedInput to pressed.4) If Counter is zero, then set DebouncedInput to not pressed.5) If Counter is any other value, then leave DebouncedInput at its previous state.6) Repeat for as many additional inputs as you need.1-2 implement the integrator, 3-5 implement the Schmitt trigger.Any reasonably competent person should be able to understand and correctly convert this pseudocode to actual code, for their target hardware and language of choice, in just a minute or two. Anyone who can’t should work it out on their own, rather than relying on a trivial canned code example, because they need the practice!",

He is missing though that the whole point of debouncing isn’t just how to read the button, but dealing with the fact that mechanical buttons almost always “bounce” and actuate multiple times. If you have it in a fast interrupt, it will fire more than once with every press!toto says to just compare it to what it was and see if it changed, but again, you’ll just end up with it actuating multiple times if it bounces.Then others say do it in hardware, and others say do it in software. But really, there isn’t a best answer to that, though “hardware” is the more reliable option. Software is “free” until you run out of overhead, then its very expensive (paying a coder to do weird workarounds, or selecting a faster processor). Putting an RC filter on a button will pretty much never fail, and you don’t have to pay your programmer to deal with it. It may not matter in some applications, but if you’re runnings a single threaded processor and doing something complex, you might not want to sit and wait for 10 or 20 milliseconds to see if the button calms down.Hardware, then, seems like a much safer option. It adds two components per button, but does not require any additional thought, and it much less likely to get screwed up. With all the crazy ideas people have here on software debounce, it’s clear that there are plenty of coders who will screw it up and then waste time trying to fix it. Best then to do hardware and not have to worry about it, unless you have a lot of buttons and/or have plenty of processor idle time.-Taylor",

But I’m seeing a lot of people talking about solutions, without actually defining the problem, and I think I’m seeing a lot of people making incompatible assumptions about what exactly the problem is.Before you make a claim about what the right way to debounce a switch is, you need to know: (1) How long the bounce event lasts, (2) How much delay between button-press and software-response you can tolerate, and (3) What’s the minimum length of button-press-and-release cycle (or release-and-press cycle) you need to capture.For instance, if a bounce lasts 10ms, and you only care about a 50ms response time and don’t care if you miss press-and-releases shorter than 50ms, then debouncing is trivial — just sample every 25ms. If you sample in the middle of a bounce, it’ll either match the signal before the press or the signal after, and the worst case is it matches the one before and so you don’t pick up on the keypress until the next sample — which is still within the 50ms window.",

If any switch doesn’t match the last state stored in the ‘last_state’ variable (see step 5), then set ‘test_switches’ flag to test again later.3. Do some stuff. (execute some subroutines that won’t take forever to run). A delay loop can be substituted, but why not do something useful while waiting for the debounce.4. If the ‘test_switches’ flag is set, then retest the switches. If any of them don’t match ‘last_state’, then execute the function associated with the specific switch state.5. Store the new switch values in last_state variable.If no switches have changed, then only a few cycles will be used on the switch debounce code. The point is to minimize the code needed as well as not have to resort to using timers or delay loops. A timer is a valuable resource which shouldn’t be wasted on switch debounce, and delay loops are wasteful.",

[AviatorBJP] is building some impressive automatic transmissions using LEGO parts. Your best bet is to check out
his YouTube channel
as he’s got a slew of videos related to topic. We’ve embedded test footage of first and second generation vehicles as well as the most recent flywheel design after the break. But we’re getting ahead of ourselves, let’s look at how the system works.
Each transmission centers on a mechanism that includes hinged arms attached to a central axle. The arms are held together with a rubber band but as the axle spins faster, they overcome the elastic force of the band and begin to pivot outward. This pulls the shaft in one direction, moving its gear up to the next position in the transmission box. To test the system [AviatorBJP] uses a treadmill. A string is attached to the front of the vehicle to keep it in place and the treadmill is switched on to simulate engine power.
This design is quite brilliant, and he’s not keeping it to himself. If you’ve grown tired of the
manual LEGO transmission
you built, you can follow his multi-video build process to make one of these for yourself.

Paging System For Your TV Remote

[Matt] brought together a TV remote and cordless phone to
add a locator system to the remote control
. One of the best features of a cordless phone is the pager button on the base. When you press it the handset beeps until found. Matt gutted one and got rid of the unnecessary parts. He then cracked open his TV remote housing and inserted the telephone handset’s circuit board, speaker, and battery. The base station is used just like normal to locate the phone/remote combo, and has been modified with a charging cable to top-off the telephone battery which powers everything in the newly hacked unit. [Matt’s] demonstration video is embedded after the break.
It’s too bad that he got rid of the microphone. It would be interesting to take calls on this thing.

DIY Print Head Experiments

Inkjet printheads are a pretty rare thing to see done in home workshops. We would love to see more and got really excited when we saw this
single nozzle, drop on demand, head being built
. using a piezo disk intended to be a cheap buzzer and some reprap magic, [Johnrpm] got some results. [Madscifi] has been refining the design of the nozzle and the two have shared the process with us. Since it drops a single droplet of liquid, it can be used in a variety of manners, such as dropping plain old boring ink, or dropping a solvent into a powder for some 3d printing. You can see an example of the 3d printing in sugar above.

Embedded RFID For Online Passwords

"windows 7"

[Jair2K4] is using his
unique RFID tag address as an online password
. We’d bet that if you went far enough to get an implant in your hand you’d continually search for a reason to use it. Wanting to do more than just
start his car with a wave of the hand
, he built an interface module out of an Arduino and a Parallax RFID reader. Using a program called
AAC Keys
on Windows 7 he emulates a keyboard using the input from the Arduino. When it comes time to login he types his username and parks the cursor in the password box. By holding the RFID implant next the reader, the ID is dumped as the password, along with a newline (might be a carriage return, we’re not certain) character which submits the login. Take a look for yourself after the break.
On the one hand, nobody will be able to steal his tag as easily as they could steal one that is on a key ring. But we know RFID is rather notorious for a false sense of security. As long as you’re not using it for state secrets we think it’s a nice solution.
Update:
After reading the comments on this feature, [Jair2K4] made some changes to his code. It now reads the tag and verifies it with stored data, then spits out whatever password you wish (making it easy to change passwords from time-to-time). He also added servo control to the sketch.

That way it would at least be a little more secure (different passwords on different sites, password is not simply the ID). As well it might be safer to write this as a firefox plugin.

NES Controller Gets A Rumble Pak

"controller",

"vibrate"
] |
Add some feedback to an original NES controller
by making it vibrate. This feature is often known as
Rumble
Pak
, a controller add-on for the Nintendo 64 which vibrated as a game feature. This version adds a small DC motor (in the upper right) with a screw soldered off-center to the motor shaft.
[Andy Goetz] and his friend built this as a robot controller, taking advantage of the latch and clock pins. Normally, nothing happens while both pins are held high, a signal that they easily patched into using an AND gate. This is actually a neat find, as the addition of an internal microcontroller could add bi-directional communication when the latch is high and the clock is strobed.

[Niklas Roy] wanted to create electricity from moving water so he came up with this
hyrdopower generator
. It is part of his grand scheme to rent out small personal fountains made from buckets. They need electricity to run so he hooked up the generator to the water jet of a public fountain. It should be possible to use this setup with falling water in a similar way that
other generators
do.
To build the device he cut fins out of PVC pipe to use as the scoops. They are attached to a Shimano hub generator, meant for producing power while you pedal. The hub is mounted in the front for from a bicycle, which can then be mounted anywhere moving water is available. The only thing that worries us about the setup is [Niklas’] comment that being showered with water didn’t destroy the hub right away.
See the hub and the smaller fountains in the clip after the break.

I discovered that it worked better with the fan on the inside of the window.I used it for about two weeks – putting it in the window when it got hot, then taking it out when my uncle was due home. Then the radiator started to leak because it fell out of the window one time to many – then, as now, my mechanical skills were no match for my imagination.So I started going to the YMCA, mostly because they had A/C. A month later, my uncle got his water bill and went ballistic.

Learning To Walk, A Tutorial On Making Bipeds Walk

"gait",
"walk"
] |
[Robert Lam] has produced a number of video tutorials, his latest being a
tutorial on how to make a biped robot walk
. He is mainly covering the individual motions and actions. He doesn’t go into any specific programming, but rather breaks down the act of walking into several motions and discusses the reason you need them as well as some variations. For some this will seem like obvious observations, but we’ve seen plenty of biped robots that attempt to walk without shifting their weight.You can watch this video after the break, but be sure to dig around in some of his
other tutorials
for plenty of good stuff.

Creepy HDD Activity Lights Just In Time For Halloween
|

[
"Case mod",

] |
We almost skimmed right past this
spooky HDD activity light
thinking it was just another set of LEDs wired to the motherboard. However, they explained right off that they didn’t want just another blinking light on their case. They wanted it to change its intensity smoothly based on hard drive activity. While there are a million ways this could have been over engineered, we think they did a pretty good job of simplifying the circuit. The bill of materials is pretty much just a handful of resistors, LEDs, an opto isolator, and a capacitor. The effect, is quite nice and can be seen in the video after the break.

A simpler way to do it would be to have the HDD light directly turn on the base of an NPN transistor, which connects the capacitor/LED’s to 5V. Thus while the HDD activity pulse is high the capacitor will charge and the LED’s will light, and when the HDD line goes low the transistor turns off and the voltage on the cap is discharged through the LED’s, giving the same dimming effect.

Oogoo, A Home-made Sugru Substitute
|
Phil Burgess
|
[] |
[] |
If you follow Instructables.com, it might seem like every third article lately is about
Sugru,
the nifty air-drying silicone putty that’s good for all manner of repairs and custom parts. It’s fantastic stuff (and we love their slogan, “Hack things better”), but one can’t (yet!) just drop in on any local hardware store to buy a quick fix…so [mikey77] has
cooked up a recipe for a basic Sugru work-alike
. His “Oogoo” (a name likely inspired by
oobleck
) is a simple mix of
corn starch
and
silicone
caulk.
A two-ingredient recipe would hardly seem adequate material for an article, but [mikey77]’s left no stone unturned, providing an extensive tutorial not only on mixing the compound, but how to add colors,
cast
and carve custom shapes, and how his home-made recipe compares to
the name brand product
. As a bonus, the article then drifts into a little Halloween project where he demonstrates etching conductive cloth, how to make
conductive glue
, and other hands-on shenanigans.

"content": "While this post may be older, there are still people out there running across this. Do not use bleach….bleach and vinegar reacts to release chlorine gas…. You may ask how vinegar got into this discussion but the strong smell of silicone is acetic acid (vinegar). I’d suggest sticking to corn starch. I’m using it to seal the ridges on my metal roof to keep wasp and yellow jackets from building nests. I took an old piece of metal and turned it upside down and pressed oogoo into the ridge. I put just a small smear of oil on the metal to help it release. Making about 18″ long logs. It’s absolutely perfect and cuts into 1/2″ pieces very easily. I put a small smear of pure silicone on the plug and slide it in the hole. Of course there are foam piece made for this, but if your roof is already on this works very well",

Starts to thicken in about 10 minutes, and stopped sticking to my vinyl gloves about the same time.The file handle is nice, and at 1/4″ thickness is enough to stop it digging into my hand. The mold captured every detail of the plastic parts.Note that there seems to be a secondary curing about 24 hours later, with a strong acid smell. The 5-min epoxy I tried casting around this time remained tacky where contacting the oogoo, so a longer cure time for the oogoo may be required for casting.

Old timey pics with a new timey camera
Update:
We’ve already looked at this one… see
the full article
for all the details.
One way to get old-looking photographs is to use a vintage camera. Then again you can just connect a 1908 lens to a modern dslr with great results.
[Thanks MS3FGX]
Cheap iPad mounting bracket
Need a way to hang your iPad but don’t want to spend some bucks? [Tumbleweed]
used a $3 plate hanger
to do the trick.
Hand engraving
You can get free laser engraving when you buy an iPhone but
it won’t look as good as this does
. [Viljo Marrandi] spent eight hours on this, but most of the time was spent resharpening tools dulled by the tough metal.
Let time prevent your computer from going idle
Want to keep your screen saver from running? No need to change settings, software, or use special hardware. Just
set your mouse on an analog watch
and let the moving hands jiggle it around. [Thanks Lovro]

Chumby Takes Its First Steps
|
Caleb Kraft
|
[
"Robots Hacks"
] |
[
"biped",
"chumby",
"freescale"
] |
[Eric Gregory] has gone a bit mad scientist on the Chumby,
turning it into a bipedal bot
. We expected all kinds of cool
chumby
hacking, but we can’t say we saw this one coming. [Eric] points out that with a 454Mhz processor, 64MB of RAM, 2GB of expandable storage and a USB host port, the Chumby is more than capable as a robotics platform. With the addition of a mysterious and soon to be announced sensor board, he has made this chumby into a walking biped. While anyone who can write programs for linux, or even write flash applications can create software for the chumby, [Eric] chose to port the
Robot Vision Toolkit
over. This opens the doors to people who can write in Basic or who have written for the C64 or Apple][. You can see a video of this guy in action after the break.

Building A Recumbent Trike From Old Parts

"bike",
"recumbent",
"trike",
"welding"
] |
This recumbent trike was built using parts from three salvaged bikes and without welding. These bikes are a bit easier on the back and neck than the traditional riding position. This one also allows for a shorter pedal crank which was a concern for the creator, [Barry Millman]. Not only did he do a fantastic job of making the thing, but
he shared the project in verbose detail
.
It’s a good build. It won’t win a prize for light-weight design as it includes a big chunk of plywood. But it is worth the weight hit if welding is not an option. For your viewing pleasure you’ll find a short parking lot test-drive of the finished recumbent after the break.
Oh, and if you want a more dangerous cycling build, try this
over-under tandem
.

I fantasize building a folding tadpole recumbent trike.3. Recumbent. In some of the bike world, it refers to the placement of the feet, generally, in relation to the body.

STM32 Discovery is an ARM Cortex-M3 prototyping platform
. Coming in under $10 puts it right along the lines of
their 8-bit offering
, but this one is 32-bits with 5 KB of RAM and 128 KB of programming memory. It runs a bootloader and has on-board USB for easy programming. They’ve even got a trio of crippled IDE’s to get you started.
Unfortunately this is following a growing trend with the exclusion of Linux support. [Gordon] wrote in to let us know that there is hope in a couple of forms (but not using the USB functionality). The first is
a serial programmer using the RS232
that [Paul] came up with (there’s a lot more on his blog so spend some time there). But you can also
use the serial debug protocol
to program the board.
Either way you’ll still need a method of compiling the code. We’ve had great success rolling our own
GNU ARM cross compiler using this guide
. Or you can grab a pre-built package by downloading
Sourcery G++ lite
.

The free versions will still give you more than enough to play around with for hobby purposes. The IDEs themselves are, for the most part, fully functional (some of them lack the really advanced debug features, but they’re fine for personal work.)@Oren Beck: what are you going on about? If you don’t like how Raisonance manages their free trial versions, use one of the other two officially supported toolchains, or find your own. I don’t think it’s logical to slam ST for something that’s really got nothing to do with them. If Raisonance or anyone else did the same thing for an Atmega8L compiler for the oh-so-shiny-paragon-of-hackerdom Arduino boards, would you rage against Atmel? Not that I’m defending ST in particular here, the same goes for anyone.Yeah, the compiler limitations annoy me too. But as an embedded designer by trade, I can tell you that’s just how it is. The trial versions do give you enough of an idea to know whether or not you’re going to use the particular chip family for a project, and if you are, you can justify the cost to buy it.Keep in mind the target market here: They were literally _giving_ these things away free at ESC a few weeks ago – I got one one of them, as well as one of the STM8L boards – they had huge bins of them. They’re targeting professional designers who will use these in mass-market products, 50K+ units where the economy of scale will take over.",

Unfortunately every time you compile/link/program it puts up a stupid alert box imploring you to buy the real thing which gets on your nerves in seconds.I don’t think ST have thought it out properly. They didn’t with the 8 bit board either. No real pro is going to be bothered about it being $10 – the only way I can see it making sense is as an ARM Arduino. The aim is not to get current pros using it, but to get the next generation and hackers using it. How much will the use of Arduino do for AVR sales medium/long term – it provides an easy way in, and you can develop it further (you can write AVR code with Eclipse say), and it’s bomb proof (mostly) ? It was a pig getting the STM8 board to work, even under Windows, and it’s not much better for the STM32. Three different IDEs often with horrific registration and sign up code, and starter code that too often doesn’t work. Arduino – download the IDE, install Java (maybe) and go. People who buy an STM32 to play with won’t ever shell out $xxx for a professional IDE.It’s the same reason MS provide free versions of Visual Studio. A pro developing C# won’t bother with it, but it provides a lot of colleges, hackers and the like with experience of MS products.Meanwhile developing on Windows is a pain, and Linux is worse (mainly because of the hardware requirements – and the hardware is already there, it just doesn’t work properly – all it needs is a proper jumper for BOOT0 and the Serial I/O on the STM32 to be mapped onto the USB port).The driver isn’t stable at all. The ST8 board wasn’t either. It doesn’t follow the specs for a USB memory device properly, hence it continually resets under Linux. It just works under Windows, but only just – but all they do with it is provide HTML files linking to documents on the ST website. Why on earth not have (say) the flash on the STM32 as a file there, so you can program it by overwriting that file, bit like the MBED.",

"content": "@MysticPixel: The “what are you going about” comment is deserving of a fair handling. Yes, you have pointed out diverse work-arounds or alternates for the toolchain. Perhaps the concept of guilt by association is edgy in some elements- or is it? Here’s my simplest explanation for that warning.I am not contesting the “rights” of Raisonance to handle their revenue models and IP policies as they see fit. I wish them nothing but good sales. Hopefully good enough that they come over to the Free Side where many categories of Ulcers and nightmares go away :)Same applies to ST for being associated with Raisonance or any software/firmware sources they see fit to.The single deal maker or breaker is that “disable what you already have” concept. Do please recall the Sony “Rootkit” incident and what aftermath it had. Frankly speaking- Would any of us really want to give a good recommend, let alone OUR money to a company that has such IP policies? If it’s any doubt as to how a first reading says it?http://www.raisonance.com/mcu_downloads.htmlFolks, it’s a case of Informed Participation, to create another acronym. My main concern is that if we are not careful, we risk things like hitting the other download page first:http://www.raisonance.com/arm-download.htmlWhich would not clearly show the warning on the other page. Nor would we have seen that this is a company that uses Sentinel Dongles etc..Again- they have the ethical and legal “right” to handle their IP however they see fit. In an ethical world where no one would violate the stated permissions of an IP owner EVER, Perhaps all such discussions might become null.Or? The concept of truly Free and Open both in source and financial has some very compelling BIG wins. Every time any of us choose to recommend a company we’re essentially saying we approve of them. I do not approve the concept of entangling the hardware with very unfree companies, even at the “present” distance between ST and third party developers etc.Just because it’s within their rights to do what they will with their code- it’s within my rights to respectfully say NO to Dongle Locks etc. The reality is that Free Distribution turns what would be a “pirate” into your Crowdsourced PR worker! And from that concept of Worldview Hacking= Preaching the Gospel of F/OSS I close by directing anyone with doubts to look at:http://craphound.com/",

Also, the st-link based debugger interface seems pretty robust.

[Sebastian] made
a 3D mouse work with Eagle CAD
. He was inspired after using a 3DConnexion device to manipulate the views in a copy of Solid Edge 3D CAD modeling software. The system uses the 3D mouse in one hand with the regular mouse in the other.
It turns out that 3DConnecxion offers a lot of tools to get their devices working with your software. [Sebastian] downloaded the .NET example and modified it to read in data from the device. With the use of hot-keys he manages to get zoom, pan, and centering to work (see for yourself after the break). The only drawback to his implementation is that he can’t pan while dragging parts. But that’s just a small issue waiting for you to find a solution.

Sure, you’re used to doing something one way, so changing to a different way is always going to be slower at first, but that’s like saying walking is faster than riding a bike, because you keep falling off the bike in the beginning.For the rest of us that understand that two handed direct manipulation is much quicker, and less error prone than any other method once you get up to speed, I’d like to see more of this kind of thing – how about doing the same for freehand drawing apps like painter or sketchbook pro, but also with the option of page rotation in addition to zoom and pan, to capture smooth arm actions?Spork – I agree – the more expensive Spacemouse / Spaceballs have a plethora of configurable buttons that are essential in any software for professional use. I don’t really see why the cheaper (£100) SpaceNavigator has to be designed without buttons, other than for marketing reasons.I tried to build something similar to the Magellan/LogiCAD/3DConnexion devices a few years ago, but was using strain gauges, and couldn’t get them to work stably due to thermal drift, and electronics isn’t my area (I’m a Mech Eng). I believe the 3DConnexion devices work optically?Anyone (Sebastian or others?) got any good ideas for how to make a cheap 4-axis (2 axis pan, zoom and planar rotate) USB controller?

I’ll spell it out clear: two-handed manipulation may be the best solution for many programs, but in my experience, it is NOT the best for eagle (which is what this article is all about, incidentally). It has nothing to do with learning curve, I’m sure I would get used to a new system eventually (but why bother in the first place). In eagle you are almost constantly changing tools. Move/copy/delete/add trace/ripup/smash/rename/change grid/etc. and the the fastest way to do all this is with a scrollwheel mouse and keyboard shortcuts. There is no faster way AFAIK. That’s awesome that you and the author want to explore alternate control methods for programs, but I’m saying it won’t matter in eagle when you’re constantly having to switch from two-handed mouse control to keyboard shortcuts, etc.",

"content": "@Brennan.You’re wrong. I fully understood everything you wrote, and you’re now contradicting yourself. Using your left hand on the keyboard *is* two handed control, whichever way you look at it; it’s about making the most of both hands to increase input data rate.If you read what I wrote, you’d see that I agree that having direct access to mode buttons is essential, hence the keyboard shortcuts can be mapped to dedicated buttons on the more expensive devices which you don’t have to move your hand for. It’s the same from 2D and 3D CAD work in the same way that it is for Schematic capture and PCB layout.The analogy for two handed control is that of a sculptor with a knife in one hand and the clay (or whatever) in the other. Look at use of any other hand tool – usually the non-dominant hand is doing a very important job to support the dominant hand.The ergonomic principles are well proven and are as applicable to 6 axis work as to 3 axis work.You said “in my experience, it is NOT the best for eagle”. How do you even know?Have you even used a 3DConnexion device for something similar to Eagle?I use my Spaceball for my 2D Mechanical CAD work, and after 2-3 months use my production rate doubled, and number of mistakes are greatly reduced. Productivity gains are similar for others also, not just myself.Why bother in the first place? I already answered this in my previous comment – speed and accuracy for technical work. For creative drawing work it has the added advantage of capturing natural movement.If your approach to life is why bother to try new ideas, then why bother reading HAD?!@BiozzOf course a 2D mouse works fine – if you’re just doing casual work, then it’s not worth buying / learning a 3D Mouse (which is a crap and inaccurate name), but if you’re using it a fair bit, the gains are impressive.If it’s a scroll mouse that you use, then you already have a 3rd axis, so you probably do see the point. The point of the 3DConnexion devices is not to substitute the mouse, it’s to augment it.;)",

Productivity gains are not my opinion, they are fact from multiple studies.I do use Eagle, although not as much as mech CAD, that’s how I know the same principles apply.@brennanAgain, you’ve completely missed the point. Of course it’s not hard to click the middle mouse button. I’ll reiterate – the same pan/zoom/(sometimes rotate) apply to 2D and 3D CAD Mechanical CAD packages too, but it’s much more fluid to work with a 3D mouse in your non-dominant hand.Why do you use a mouse instead of a trackpad? You can achieve the same with a trackpad, but it will take longer, and be more error prone, since the ergonomics aren’t ideal.What jan and Keith Finnigan above have written are right on the money. Until you’ve used one, you really can’t see the point, and then after you have used one, you’ll never go without one.Just because with 2D work you don’t need 3 or 4 of the possible 6 axes, doesn’t mean that the principles don’t apply – they do.I guess some of you guys just don’t get it, and refuse to believe that there might be a better solution. If you do get the opportunity to use one, then please try it. I guarantee you’ll be surprised.@darwinsuvivorYou’re absolutely right, 3D mouse is a poor description, and I think that’s the problem that most people who don’t get it are having here.A mouse is an isotonic (not like Lucozade) device which gives control proportional linear control in 2 axes (i.e. a horizontal plane) to a given scale or gain (unless you have acceleration turned on). X distance with the mouse gives X*C distance on the screen. And of course it controls the pointer.The Spacemouse / is more akin to a joystick than a mouse – yes. It’s a mostly isometric (static) device, that can move a small amount against springs in any direction – 3 axes rotationally and the same 3 axes linearly:http://www.engineerlive.com/Design-Engineer/Computer_Systems_Software/The_economic_payback_of_3D_mice_as_a_user_interface/20832/The further you push the ball or puck away from it’s home position (by applying force), the faster the *rate* of movement of the workpiece or page on the screen. The ball or puck is very sensitive to distance/pressure applied, which allows very controlled fine or fast control. Usually you will stop the workpiece / page before you start clicking away at it with your regular 2D mouse.Note again that the spacemouse/ball does not control the mouse pointer…it controls the workpiece or page, which can be manipulated simultaneously and independently to the regular 2D mouse and pointer.Check out some videos to see how it works.",

Halloween Props: Puking Pirate

With everyone’s favorite free-candy holiday approaching, [Slouriesr] set to work building
a vomiting ghoul for his Halloween display
. He’s calling it a puking pirate and it centers around a pump and some simple plumbing fixtures.
First, the vomit receptacle was made by adding a sink drain with a pop-up stopper to the bottom of a kitty litter bucket. The drain slows the evacuation of liquid into a five gallon bucket below. In that bucket you’ll find a float switch pump used to keep water off of a pool cover. As the bucket fills up the pump turns on and empties the water through a hose ending at the ghoul’s mouth. The result is a 20-second puke cycle sure to delight the trick-or-treaters. Sure, there’s a lot of work to be done to get this guy looking the part, but what a great idea!
Help keep us in the holiday spirit
by sending the details
on your latest prop build.

[Fred Keller] and [Judy Foster], both retired, are proving that age is just a number. What you see above is a nostalgia inducing full size
driveable Radio Flyer
red wagon. The base of which is a 1976 Mazda pickup truck, while the wagon portion is a mishmash of wood, fiberglass and bondo, detergent bottles,
and more
. Even the steering wheel has been retrofitted from an actual wheel from a wagon. We were surprised to find out the entire conversion only took the two 11 months to complete (finishing this past august), and even more confounded to learn the vehicle is completely street legal.
[Thanks Rob]

Adding Mobile Control To Your Gardening

"firewall",

"winphone"
] |
[The Cheap Vegetable Gardener] wanted to check in on his garden from the road so
he wrote a control app for his WinPhone
. The hardware work is already done; having been
built and tested
for quite some time.
The implementation comes in two parts, both shown in the chart above. The grow box is behind a firewall as you don’t want random folks turning on the water and grow lights on a whim. The first part of the interface takes care of this separation by providing a set of functions on the host machine. The second portion is the phone app itself which calls those functions and displays all the pertinent information from the status of the lights, heater, exhaust, and water pump, to the current temperature and humidity. He’s even used
Google Charts
to graph data over time. The app itself took about two hours to code with no prior experience, a testament to the level of approachability these tools are gaining.

Maybe it is because I use CFL and do not have the heat signature or power usage to be investigated@fartface, I completely agree (probably could be done with $15 worth of timers) though I am in the school “if it is worth doing, it is worth overdoing” One of the problems is watering at the right time, sure I can water every other day but depending on temp and humidity I shouldn’t water for over a week sometime and daily on others. Funny thing is I know a guy who had an internet flushable toliet, but he did have an legitimate reason to do so. He had a cabin in dry/windy Nebraska and the toliet water would slowly evaporate ending up making the cabin smell like a sewer when it dried completely up and letting all the nice gases come in.

[SXRguyinMA] built a replacement top bezel for his computer case. He wanted to
add vents that would automatically open or close
based on the cooling needs of the computer. With some careful measurements he modeled the parts in Sketchup and sent out for them to be cut from styrene with
a water jet cutter
.
The parts
came back looking great and the
assembly of the shutters
went swimmingly. The bezel also includes a lighted screen for temperature information, as well as the front USB ports, headphone and mic jacks, etc. Hidden underneath is an Arduino board and servo motor. The Arduino polls the temperature and drives the servo to adjust the fins accordingly. There’s even a supercap in the circuit that will close the vents when the PC powers down or when power is unexpectedly lost. See it in action after the break.

Closing them makes it so the dust floating around doesn’t float it’s way down into my case :)And I couldn’t find a way to use the +5v standby to power the Arduino. I use the 5v as the sense pin to tell the Arduino if the computer is on or off, and adjusting the vents accordingly (open or closed). This same +5v triggers a relay which lets +12v through to a +5v red to charge the caps. The reason for the relay is the system would backfeed through itself and it would not take 5v away from the Arduino’s sense pin, and the vents would stay open until the caps drained.I plan in the future to put the ATmega320 on it’s own custom board with the backup power circuitry all integrated into the board, rather than on 2 boards.I had thought about the idea of leaving the vents open for a few mins after the computer is off to let the heat naturally migrate out, but like others have stated, once the components are powered down they’re not generating more heat so it’s not really needed :)And yes, I did retain the 2 140mm exhaust fans under the vents that came with the Tempest EVO. The fans are controlled via the NZXT Sentry 2, along with every other fan in the case (8 total).Also, thanks to HAD I went from 1.7GB usage on Photobucket to 13.3 :D So for those of you that check out the worklog the pics won’t be visible!

New A4 Jailbreak Debacle Puts The Brakes On For IPad

If you’ve been waiting in the wings for the next Jailbreak to be release you should know there’s been a bit of a speed bump. [ChronicDevTeam], which has been working on an exploit for A4-based iOS devices called SHAtter,
tweeted last Thursday
that the fully tested, untethered, and unpatchable package knows as
greenpois0n
would be released today. But on Friday [Geohot], who you may remember from
the PlayStation 3 Hypervisor exploit
, rolled out his own mostly untested and admittedly beta jailbreak called
limera1n
.
So where does that leave the situation? Because [geohot] used a different exploit, the [ChronicDevTeam] decided not to release greenp0ison. If they did, it would give Apple a chance to block two different exploits. Instead they are working feverishly to incorporate, test, and repackage using the same exploit as limera1n.
If you don’t want to wait, jailbreak now, but you risk problems with an unstable exploit method that is only available for Windows.

Oh [Humberto], what will you think up next? A
human Theremin
you say,
and
it’s for Halloween? Certanly this will blow last years creepy
capacitance sensing jack-o-lantern
out of the water right? Eh, not really, but still cool none-the-less. By using pairs of IR LEDs and IR photo-transistors, [Humberto] makes a simplistic distance sensor. Then its just a matter of converting that light value
into sound
, which is accomplished by using some very clever PWM square wave hacking to make a triangle wave. Also, [Humberto] goes over the process of using fast integers to represent slow floating point numbers. While none of the project is really a new concept, it certainly is put into an easy perspective so anyone can try their hand at it. All well worth the read, or you can catch a video after the jump.

We saw this picture on Flickr this morning and started getting really curious. The caption says that [Steffanhh1]
modified the Yashica Electro Shutter camera to be fully manual
. We’re not camera experts so we had to
do a little research to see what was going on here
. The Yashika Electro got its name due to how the shutter speed is controlled. You have two little LEDs that light up depending on which direction you need to turn the dial (based on ambient light?). [Steffanhh1] really wanted full control, so they hacked in a dial with a knot of resistors under it. The first test photographs are
downloading
developing, so we’ll have to wait to see the results.

Was a fairly expensive hobby, but not as expensive as color photography (I did very little color photography for myself, because I could not afford it). I learned enough about photography in general to get a job as a photographer for a local party-pictures outfit. I even got the higher-paying color assignments.Those days are long gone. I’m not sure you can even get film and photographic paper any more, it’s been so long since I bought any… I drug my old Yashica Electro-X out of storage about 8 years ago, and sold it on eBay, for what I thought was a ridiculously high price of $25.Now, anybody can shoot color photography using a camera that costs about $100 ($400 if you want to get really fancy), and print 4×6 color glossies on a $50 printer for about 50 cents a shot.

It actually works out to even more than that if you get on the endless upgrade treadmill of digital and buy new bodies every few years.

Basically, the autmatic mode works by letting light shine through a photoresistor until a certain amount of electricity has flown through (simply spoken). What i did was bisically to let the light go through fixed resistors instead of the light/photoresistor thing.@QUIN: The proof of concept indeed was a potentiometer and i had markings on it for the different speeds. However, i was missing the satisfying clicks of a switch dial, so i chose the path with the ordinary resistors. After all, my manual mode is pretty easy to make and replaces the “bulb”-setting on the camera. i instead have a bulb-position an the dial now. I someone wants a schematic, let me know… And regarding all the digital-analog-controversy: The most enjoyable thing about analog for me is that the time that i need for a picture, the dial-turning, guessing, checking and the final click. I could have taken 20 digital pictures in the same time but i am glad everytime for only one, hopefully good, picture. and yes, the hopes are part of the fun, too.

Using An Arduino Or Seeeduino For Its FTDI Chip
|

[
"arduino",
"breakout",
"ftdi",
"seeeduino",
"usb"
] |
We think of the Arduino as a rapid prototyping tool but we never thought of it as an FTDI breakout board before. [Ihsan Kehribar] wrote
a quick post to show how it’s done
. You’ll find an FTDI chip on Arduino boards that have a USB connector. It’s used to handle the USB communications on one side, and TTL serial communications on the other. The serial pins from the chip are mapped to the UART on the AVR chip, and in turn they appear on the pin headers for easy connections. Just load up a really simple sketch(available from Ihsan’s post) to make sure the processor doesn’t get in the way and you’ve got yourself an FTDI breakout board. If you happen to have a Seeeduino there’s even more functionality as the board has a selector switch that allows you to choose between 5V and 3.3V levels.
This doesn’t hold true to
the newest generation of Arduino
, as those board have replaced the FTDI chip with
an
ATmega8U2
. That’s basically and ATmega8 with native USB handling… fancy.

Once people realize what is possible using a usb enabled micro instead of an ftdi and write the OS code to utilize it you will see what I mean. Hands down the new method is better. And im not afraid to speak my mind if the facts did say that they did it purely to make clones more cost inefficient to produce, but clearly that is not the case considering they are open source, left the bootloader in and clearly did this for other reasons.But pertaining to the post any usb enabled chip can do this. Its called a CDC class device, and is a serial emulator. So the usb enabled micro in the UNO can EASILY be made to do the same thing if you understand USB. It can also be made into a MIDI device, quite easily. In the end youll see its a really really good thing how theyre doing it.",

A small, cheap spectrum analyzer with an LCD can be a fun thing to play with. But to be truly usefully you need access to raw data, and lots of it. [Travis Goodspeed] set out to make that possible by
pulling data with a GoodFET and a Python script
.
He started with [Michael Ossmann’s]
IM-ME spectrum analyzer
, which uses a CC1110 chip. The two of them are giving a lecture at Toorcon 12 (called
Real Men Carry Pink Pagers
) and this will be used as a demonstration device. After studying the datasheet he found the starting RAM address and did some further work to deciphered how the data is stored in it. From there it was a matter of working out the timing for grabbing the data, and coding a method for storing it. Now he’s looking for brave souls to help him trailblaze with this newly-discovered tool. It seems that if you know what you are doing, and have abundant patience, you can use this for a bit of old-fashioned reverse engineering.

Beefy Battery Backup Still Running After A Decade

In 1997 [Michael Butkus Jr.] found an uninterruptible power supply in the dumpster. The batteries were shot, but he needed a backup to keep his pellet stove running for heat, drive the exhaust fan to keep the smoke out of the house, and power his computer and other electronics. After a bit of head scratching he decided to
beef up the UPS using deep-cycle batteries
.
He actually built two of these. One is smaller, and
similar to what we’ve seen before
. The other is larger and uses four batteries, two pairs in parallel which are then connected in series. He’s careful to use heavy gauge wiring and 50 amp fuses for each battery, both of which will protect against the risk of fire. One thing we found interesting is that the batteries are stored in the basement, directly below the UPS which is connected via a short run of 12 gauge home electrical wire.
We were happy to see that he’s done updates at the top of his post over the years. He lost a few batteries due to neglectfully letting the water levels drop too much. He did switch over to sealed automotive batteries sometime in 2004 or 2005. Looks like things have been going strong ever since.
[Thanks Spencer]

Unbelievable. I know of one unit that lived for almost 10 years.Just after that, battery manufacturing moved to china, and the lifespan dropped to 3 years or less. Then, as if chinese made electrolyte wasn’t cheap enough, they moved battery manufacture to india. Lifespans dropped to 12-15 months, and I wouldn’t be surprised to learn that the electrolyte was produced via bilogical methods. Absolute trash.The units are being produced in Thailand and China again, and have started getting better again.But seriously, I have UPS units that were built in the early 1980’s that are still running with periodic battery changes. They’re inefficient, have mediocre capacity and take up too much room, but they’ve been running in an outbuilding in the northeast for almost 2 decades.",

Few people realize the potential for switching to better batteries in a UPS, so it’s good to see this getting some more attention.Sealed auto batteries only work if you’re very careful to limit the depth of discharge. Even one deep discharge can destroy them, or reduce their capacity severely. Regardless, they can be used successfully for a long time with some caution if you require relatively short run times.Deep cycle marine batteries are a much better option. As for the watering issue the author reports, the reason auto batteries are sealed and maintenance free is because they have a catalytic converter inside that converts the oxygen/hydrogen gas released from charging back into water.You can get retrofit caps for deep cycle marine batteries which include the same converter, and can greatly reduce maintenance. They work best with moderate recharge rates; fast charges will overwhelm the converter and cause gas release (which occurs even in a “sealed” auto battery). An example product is the “Water Miser” Battery Cap.Another alternative may be a battery auto-watering system. I haven’t used these and don’t have a reference handy, but I do recall seeing one some time ago.",

Finally, they also don’t hold a charge for that long… Let them sit for a few days, and you’ll wonder where the voltage went.Now for the cool part – they will take abuse like nobody’s business. You can treat them like an inner-city 8th grade teacher, and they’ll just keep working until someone puts a bullet through the glass.Seriously – these things have staying power.

Looks like someone figured out how to game the Reddit system. This probably has been done before, but as far as we know nobody’s actually shared the methods in detail. [Esrun] wrote some scripts that allow him to
register multiple accounts and use them to up-vote stories
.
The hack goes something like this. A script registers a group of accounts. Each uses a different IP and the only part that requires intervention is typing in the Captcha. This doesn’t take long. You can see the script interface above as well as a demonstration video after the break.
Once the accounts have been acquired a story is submitted and the new accounts vote on it. They’re not all up-votes though, as having both up and down votes puts the article into the controversial section of Reddit (which is desirable), and doesn’t rouse as much suspicion from the moderators. He ran a few tests that he shares and it seems that as long as the article is interesting, this can be quite successful.
Great, more spam with our social media please.

Add Supercaps To Your Exercise Routine

Many exercise machines generate electricity as you pedal or climb in order to run the on-board electronics. Unfortunately if you stop or even slow down too much the juice will die and your exercise program will reset. Wanting to improve on this gotcha, [Mike]
cracked open his exercise bike and added some super capacitors
.
On the circuit board he found an ATmega128 was in charge of the user interface. He probed the board a little bit and couldn’t find how it was connected to the power regulators. After some additional snooping he found it has its own SOIC regulator separate from the ones that run the display and peripherals. He takes us through the calculations he made before choosing his parts. What he ended up with is a set of three supercaps in series that add about two minutes of juice before the levels drop and the chip resets. The design of the board helped a lot as the high-load electronics (like the LCD screen) are on a separate power bus than the processor.

[Furrtek] hooked up his
Game Boy printer for use with a PC
(
translated
). The two-part hack started with a cable to attach the device via USB. A Nokia interface cable was used as a base to translate the USB signals into serial, and an ATtiny45 microcontroller added to talk to the printer. He did a great job of free-forming the circuit alterations and fitting it back into the plastic USB plug housing.The next step was to write some software. Using VB6 he coded an application that loads in an image, scales it to fit, and allows you to adjust the contrast that the thermal printer produces. For testing purposes he’s reusing old receipts. See it in action after the break.

Bench Supply With Current Limiting

This is a bench
power supply with adjustable voltage and current limiting
. [Sylvain’s] creation can regulate 0-25 volts while sourcing 0-5 amps. Current limiting is a nice feature as it will allow you to test your prototypes to ensure the power regulator you choose will not be over or underpowered.
This supply is really a two-in-one. The case has two separate circuits so that you can have different power rails going at the same time. There is a microcontroller involved, but the ATmega32 doesn’t do anything more than measure the voltage and amperage and drive the graphic LCD screen. Two potentiometers are responsible for setting the voltage and limiting the current.

Turtles All The Way Down, 40 Propeller MCU Skyscraper

Why bother
interconnecting 40 Propeller
microcontrollers one on top of the other? For the power that comes from parallel processing of course! [Humanoido] put the setup together for a total of 1280 ports, 640 counters, and more all running at 6.4 billion instructions per second
for the low low price of 300-500$ by our count
. The “skyscraper” even comes complete with software and schematics, promising developers the ability to expand or adapt for any venture. Why would we need such a setup in the first place? For any of the following: vision tracking/modification, artificial intelligence, advanced robotic control, or more.
Related: [Humanoido] loves putting MCUs together, check out one of his other creations the
Basic Stamp supercomputer

I was able to fit about 256 of the 1-bit processors with about 50% utilization on a spartan 3e starter kit, but intuitively since the processors in Hillis’ dissertation are essentially 1-bit ALU’s with some addressing, I felt as though the density could be vastly improved and much of the gate count was likely going into the memory addressing and block ram.i love to see folks these microcontroller clusters, and it’s even more impressive when they build some simple software demonstration to go along with them. i’m not sure that it has any particularly useful applications other than as an academic persuit, but that’s more than enough! :)",

In computers only a certain number of operations can be executed in any one cycle of the clock, dictated by their bit rate(32 or 64 for personal computers). Newer desktops operate in 64-bits at their clock speed eg; 3.6GHz 64-bit.Now each segment of code has a size associated with it, so moving a data from one section of the RAM to another may require 4 bits to accomplish it. So you can do this operation 16 (4/64) times per cycle. Since your CPU goes at 3.6 billion hertz you can move that data around 57.6 billion times per second. Moving it counts as one instruction,so if all the computer did was that move operation it would operate at 57.6GIPS.",

[Sebastian] is trying to improve the responsiveness of an electric keyboard. He was unsatisfied with the lack of adequate sensitivity to keystroke. The first step in his process was to measure how fast the quickest keystroke actually is. By setting up an LED and phototransistor and taking some measurements he found that sampling at 1 kHz would be more than adequate.
With initial testing complete he ordered some CNY70 transmissive/reflective light sensors that can be place below the keys. He measures the sensor with the ADC on an ATmega16 microcontroller. Running at 16 MHz he can sample each of the eight analog-to-digital converter channels at 1202 Hz. After doing a bunch of math he put together some lookup tables that are used to translate the ADC data into midi signals. We’ve embedded a video of
one sensor controlling the midi program
PianoTeq. [Sebastian] also sent us a schematic of one node in the sensor network (see it after the break).
When everything is said and done he plans to use eleven ATmega16 microcontrollers to address the 88 keys, with an additional microcontroller to act as the master using a two-wire interface for communications.
Update:
[Sebastian] put up a webpage with a fairly verbose description.
Reading it straight from the source
really clears up a lot of questions.

But I have to admit I do not know much about OSC so maybe this will be a future thing ;)@smoker_dave: The wirering is perfectly fine. I used that setup to spare one wire, as the anode of the LED and the colector of the PT can share one pin. If I used the resistor at the colector I would have an inverse signal and needed one more wire. Have a look at this application note:http://www.fairchildsemi.com/an/AN/AN-3005.pdf@KeyboardFan: Actually I already had some unwanted aftertouch when testing it on my piano. I solved it by calibrating the sensor so that the maximum ADC voltage is reached when the key slightly touches its felt stop. If one can live with a reduced precision or uses an ADC with more resolution you can use the felt compression zone for aftertouch effekt. But thats certainly the last thing I’m gonna implement as I don’t have a synthesizer that benefits from aftertouch.@bluecarbuncle: I decided to use 11 atmega16 controllers because they’re cheap and my physics engine runs fast enough to calculate the 8 ADC channels at their maximum sample rate. Of course there would be bigger controllers or muxed adcs that would simplify the circuitry and maybe even reduce the costs, but I wanted to create something that everyone can build without having SMD parts to solder.",

[Ben Kurtz] is
doing a little WEP cracking
but in a bit of a different way than we’re used to. WEP cracking makes us think of war driving; driving around with your laptop open, looking for WiFi access points, and stopping to run some software when you find them. [Ben’s] way is similar but different in one key way, he’s using an iPhone as the frontend.
This started as a way to find a use for some leftover equipment. He threw together a Linux box and loaded up
Aircrack-ng
, the software we often see
used in penetration testing
. To remove himself from shady-looking activities in public he coded a web interface using the Python package
Turbogears
. It uses screen, a program often used with SSH to run services concurrently in different terminals, with the option to disconnect without stopping the processes. Now it’s just a matter of parking the hardware near an AP, and doing the work in a browser on your mobile device. You can check out the script he wrote, as well as installation instructions, in his post linked above.

Yet.Rest assured – you’re already tagged, bagged and about to be slagged.

[Alexsoulis] needed to burn the Arduino bootloader to a slew of ATmega328 chips. Instead of sitting there and plugged the chips into a programmer one at a time, he build
a robotic microcontroller programmer
.
It starts with the DIP package microcontrollers in a tube, with a servo motor to dispense them one-by-one. An arm swings over and picks up the chip with a fish pump powered vacuum tweezers similar to
the pick-and-place head
we saw recently. From there the chip is dropped into a ZIF socket and programmed by an Arduino. Once the process is complete it is moved to the side and the process repeats.
We’ve reported on
using an Arduino as an AVR programmer
but we’ve never actually done it ourselves (we use an AVR Dragon programmer). Take a look at the video after the break and let us know if you think the actual programming seems incredibly slow.

BIOS Password Cracking

"bios",
"bruteforce",
"checksum",
"laptop",
"password",
"python"

[Dogbert] took a look at
the security that goes into BIOS passwords
on many laptops. He starts off with a little background about how the systems work. People are bound to forget their passwords, so when you enter a wrong one three times in a row you get a message similar to the one above that locks you out until all power is removed from the system (then you get three more tries). But check out that five-digit number in the picture. That’s a checksum of the password. Some BIOS versions display it automatically, some require you to hold down a certain key during POST, but it’s the pivotal data needed to crack the password.
[Dogbert’s] post doesn’t go into verbose detail about the algorithms he uses to brute force the passwords. But he has posted the Python scripts he uses to do so. Learning how to generate the passwords based on the checksum is as simple as studying the code, which is often the best way to learn.

The details of how it is stored and handled are entirely up to both the ODM and IBV. It is even possible for a separate microcontroller to handle the entire process so even the hash is never stored where it could be dumped.As for the old pull the battery trick, this depends on the BIOS using the batter backed up ‘CMOS’ that, IIRC is part of the RTC. It has become increasingly common dedicate a block or two on the flash part to store nonvolatile data rather than using the battery backed up RTC CMOS. So pulling the battery won’t accomplish much.

NYC Resistor Takes On The Machine

Here we are with Episodes
two
and
three
(aka,
NYC Resistor
part one and two) completing the Take on the Machine Hackerspace challenge we mentioned
a while back
. For the challenge NYC Resistor took an old style slot machine and converted it into a drink mixing deviant; even making the device post a Tweet for every drink. However, it seems to be lacking refrigeration of some kind, could this be the downfall of a potential winner for the challenge? Up next is the Hackerspace Pumping Station: One: do you think they can compete? Is there a particular Hackerspace you can’t wait to see? Let us know!
[Thanks
Deven

Upgrading The Freetronics Twentyten With A Real-time Clock
|
Caleb Kraft

[
"Arduino Hacks",
"clock hacks"
] |
[
"real-time"
] |
[John Boxall] finds himself doing a fair amount of
projects that require a realtime clock
. He does fast and frequent prototyping, usually using the
Freetronics twentyten
which is an Arduino alternative that boasts a few features like a nice prototyping area, edge visible LEDs, and Mini USB. What is lacking, however, is a real-time clock. Instead of making another shield type system, he just wanted to permanently add this feature to his board. He shares the whole process is photographed and explained quite well for anyone who would want to follow along.

Cheap Robotic Hand
|
Caleb Kraft

[
"Robots Hacks"
] |
[
"fingers",
"hand",
"PICAXE"
] |
[Mazvydas] shares with us, his
cheap robot hand
. He was inspired by
this project
, where someone used an Arduino and a glove with some flex sensors to control a pre-made hand. He wanted to go a little more DIY though. He chose a picaxe microcontroller and constructed the hand himself out of twine, some plexi-glass, and some rubber hose. He does ultimately plan on adding glove control as well.
Unfortunately there’s no schematic or source code. Maybe if we ask really nicely he’ll share.

It seems both established and popular, but I’m surprised it has yet to make it into hack-a-day (until now, of course).Maybe this should be filed under ‘classic hacks’?NB: Yes, this is cheap and easy — but the limit to the amount of force you can put out is whatever is lowest, between the tensile strength of the twine, the compressive strength of the tubing, and the actual force of the motors.I have seen some variants that use segmented tubing in order to better mimic the segmentation of fingers, though extra motors are needed to gain the same degrees of freedom held by those segments (not to mention some trickier programming). There are also variants that separate the thumb out onto a separate board, which can be rotated on the yaw and rotated closer to or further away from the main body of the hand, better mimicing the abilities of the human hand and giving the manipulator opposable fingers — pretty important if you want it to be functional rather than just pretty!",

[Matt] has mixed up a batch of
two RFID
reading door lock
systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the Parallax RFID readers (
for cheap, remember?
) and an Arduino, [Matt] is able to parse an RFID tag, look its number up in a database, and then have a computer announce “Access Denied” in a creamy “Douglas Adam’s sliding door of Hitchiker’s Guide” kind of way with Python.
Good books aside, catch a
not as exciting as you’re thinking
video after the jump.

What’s thirty-seven feet tall, has ninety-one flamethrowers, and is controlled by an Arduino? Why it’s
Pyrosphere
, an interactive art piece at this year’s Burning Man. It lights up the night along to the music in a way that makes us want to set up a lawn-chair and watch the show. You can see for yourself in the video after the break, but you really should have thrown on the
LED fur coat
and gone to see it in person.

Hydrogen gas from a zinc/hydrochloric acid reaction was more rapid burning, more like a quick flash.He also did two balloons, one with straight hydrogen, one with a 2/1 ratio of hydrogen to oxygen. The same volume total. The hydrogen balloon made a nice bang, but the hydrogen/oxygen balloon was much louder and had a shockwave the whole class felt.He also had a tiny fragment of sodium metal end up in the trash can, and almost burned down the science building when it got wet.

I didnt know the difference between a diode and a transistor! I had basically no code writing experience, with the exception of a little html I had messed around with. I bought an arduino and the “getting started with arduino” book. Just over a year later, I finished the Pyrosphere, with a little help from my friends.

For all those times you need to broadcast your own access point where there’s no outlet [Larry] shows us how to
make a solar-powered hotspot
. He started by slapping a solar panel on the lid of a cigar box and attaching it to five rechargeable AA batteries inside. These power the mainboard from a router which is the perfect size to friction fit in the opening. It has been flashed with a copy of DD-WRT, and set to scan for open WiFi connections. When it finds one it connects and rebroadcasts its own WiFi signal to the surrounding area. He leaves it in the back window of his car and uses it to get on the net during lunch.

If we are talking about bittorrent, it would be trivial to setup N number of routers running dd-wrt with a bittorrent client. They would all connect to N of your neighbors’ APs. Then when you want to download something, a script on your computer will break up the torrent into N equal chunks and give each router a portion to download with no overlap. When a router finishes downloading its portion, it would upload it to your computer. If you want to use this for other protocols (ftp, http,…etc) you’ll need a central router to split up the tasks but most likely you won’t be able to get it to work for all file downloads. For surfing the web, the central router can download the html file, and then break up the various objects in the page to be downloaded by the other routers. So your computer would actually be surfing the cache of the central router. It would work best if the central router continuously downloaded all pages and links X number of levels deep ahead of you as you surf. This wouldn’t be that great for real time internet events (ebay auctions, stock quotes…etc).Having said that, this is probably a quick way to get jail time and get banned from owning technology. Stealing your neighbor’s internet is bad enough. You want to steal from multiple neighbors, and then most likely use their connection to do something even more illegal.",

You won’t find those familiar steel balls inside this
mini-pinball cabinet
. That’s because [Luis’] latest creation is a fun way to play virtual pinball. The playing field is a 10″ LCD screen with an accompanying 8″ screen in the marquee. Inside the well-crafted case you’ll find a mini-ITX motherboard running
HyperPin
, a frontend software suite for LCD-based virtual pinball. He’s also using
PinMame
for the score board that was often provided by
a gas plasma display
on newer mechanical machines. There’s video after the break, and take a moment to check out [Luis’]
other mini-cabinet builds
.
What’s that you say? No substitute for the real thing?
That’s exactly what [Ben Heck] thinks too

This
programmable power supply
is the perfect addition to your bench tools. [Debraj Deb], who previously
built a whole house power monitor
, designed this build around a PIC 18F4520 microcontroller. The desired voltage is set with an attached keypad, resulting in a digital output on the 8-bits of port D. The port connects to another protoboard with an R-2R digital-to-analog converter resulting in the target voltage. A set of transistors amplifies the current and a power transistor then takes care of the final output. After the break you’ll find two videos, the first walks us through the hardware and the second demonstrates the device in action, along with measurements of its performance. This certainly provides a lot more functionality than
an ATX power-supply conversion
.
Update:
A big thanks to [Debraj] who sent us a code package as well as
the schematic
(PDF) used during testing. We’re having trouble getting the code package up for download right now. Check back later, hopefully we’ll have it up soon.

For starters, it looks like he used standard 5% resistors for the R2R ladder, this is a FAIL in itself. An 8-bit R2R ladder has a resolution of 256 divisions, so using 5% tolerance resistors is not only terrible for accuracy, it also means the whole thing isn’t monotonous anymore.There is no gain control around the opamp, which is another huge beginners mistake. The thing is probably oscillating like crazy, but the output capacitance is so big you can’t see it on the scope. This huge capacitance also makes it very slow, as you can see whenever he changes the output voltage.The circuit diagram doesn’t show any kind of current measurement or control.There doesn’t seem to be any kind of power supply decoupling whatsoever.There are far better designs out there, with complete schematics, proper voltage and current regulation (down to 0V and 0A), complete with source code.This guy has a lot to learn, but at least he’s trying.",

I plan to change the entire DAC setup to MCP4725. Its a 12-bit, 5V DAC from Microchip. Using this will give me 3 advantages — 1) the interface is I2C, which will let me use lesser pins, 2) I will have higher resolution (8bit vs. 12bit) and 3)No issues with 5% tolerance resistor :-) This demo is more for a proof of concept.On compensation of feedback amplifier, yes, there are huge oscillations and I have to work out compensation — capacitors in -ve input to output, but did not had the capacitors around, so managed with a large capacitor on the output. Also, I am OK with slow response which I feel is better than overshoot from set voltage.I have provision for current limit. Check the blue color shunt resistor (0.15ohms) that I have on my analog board. I am yet to amplify the current signal thro an op-amp and feed into the controller. That part will be covered in the 3rd part of my video.Power supply decoupling, I have not shown on the circuit, but they are integral part of the hardware.",

This
beautiful music syncronized double helix
was made by Syyn labs. Last time we saw them, they had created
that amazing rube goldberg style music video for OK Go
. This 100 foot long LED DNA strand took over 1000 combined man hours to build. It took 512 LEDs, 32 LED controllers, 4 Arduinos, 4 computers, over a mile of wire and a very dedicated team, which included [
Eliot Phillips
]. It takes input from beatmatching/VU software as well as a 32 button console or an iPad. You can catch a video of it in action after the break, and they plan on releasing a timelapse of the build in the near future.

Our little red-eyed friend
can drive this vehicle around with his mind
. WITH HIS MIND, MAN!
This is the product of research into adaptive technologies. The process is pretty invasive, implanting neural electrodes in the motor cortex of the brain. The hope is that some day this will be a safe and reliable prospect for returning mobility to paralysis victims.
We found it interesting that the vehicle was trained to react to the rats’ movements. They were allowed to move around a test space under their own power while brain signals were monitored by the electrodes. Video tracking was used to correlate their movements with those signals, and that data is used to command the motors for what the Japanese researchers are calling RatCar.
We can see the possibilities opening up for a
mechanized cockroach
v. RatCar free-for-all. Something of a battlebots with a live tilt. But we kid, this is actually quite creepy.

These films are nothing short of horrific.Of course, heart and lung machines are descended from this stuff, but still, having seen the films of puppy heads spliced onto large dogs and the meowing of disembodied cats, can you imagine what the human experiments were like?The campaigns to villify the nazi doctors were damning and much made of the evil of experimenting on people who could not consent, and yet the rest of the world continued their own equivalent work – and have continued to do so to this day.And now, I want to vote for a quick hackaday article on creating your own GM food products – you know, the world really needs a strain of HPV-preventing tomato, anti-TB dairy products and some sort of birth-control effect corn. We could get this population dramatically down-sized in just a few generations.I mean, it’s science! What could possibly go wrong?",

"content": "“So how much ethical is to do it with rats or other animals?”Apparently, very much so. Right or wrong, animal research yields, on an ongoing basis, some considerable insights and breakthroughs. Yes, some times you have straight up skin patch tests and other such things but other times you have some really cutting edge research that can’t really be performed any other way.The alternative is to experiment on humans and nobody would argue that is ethical. Since we don’t yet have a supercomputer that can accurately simulate every atom of a human being, we use the next best thing. A mouse or rat or hamster or the like. At least we take general steps to prevent the animals from suffering needlessly, even if most are sacrificed (killed) at the conclusion of the experiment.If animal testing gets us closer to a safe and effective method for establishing communication with people suffering from locked in syndrome or gets us closer to curing Parkinson’s or helps a quadriplegic move their limbs again, I am perfectly fine with that and given the pervasiveness of animal testing in science, society at large generally seems to agree.",

"content": "This is how you can usually tell the typical attention-whore tricks in science from the experiments done as legitimate research.A legitimate experiment would be to put a camera or two above the rats, then gather the signals from the neural pathways and synching them with position data.Once you have an algorithm that predicts motion, you could run it against the logged data and see how closely it predicts the actions of the rat.They could have kept the data from the group and used it to run through the algorithms for tweaking, or used reverse correlations to try and come up with an algorithm.Either way, this experiment is basically a poorlyexecuted update to the hundreds of existing studies that consist of basically gluing insects and small animals to motors and seeing if they can learn to drive before they’re exterminated.I am all for legitimate research. I am all for using rodents and pigs to improve the state of medicine; and yet, I really dislike these stunts.you people need to get a freaking clue…@Apostl3pol“What we need is a non-invasive sensing method to target minute areas in the brain without actually sticking in wires.”Amen to that! But it’s quite a mess in there. Since the brain wasn’t built with a debugging port (as far as we can see at the moment), all we can is poke it with sticks, metaphorically speaking. It will be a glorious day for science, and maybe less glorious for mankind, when we finally get that sorted out.@Roman“you people need to get a freaking clue…”Good luck with that approach. People have clues. They are unlikely to be your particular clues, which is why they jump to different conclusions.People who say this are usually saying “You should see it my way” but seldom bother to make an argument about why “my way” is the correct way.Most of these people agree with you – rats are ours to use as we like, especially in betterment of medicine and science. I agree with this statement. However, some people are reacting to the experiment’s design and lack of conclusions more than to rats being tortured and sacrificed.@Gavin“it’s unethical to do most of it with humans yet.”Well, more along the lines of being unfundable at the moment due to the “creepiness factor”, but given time I think we can safely say that DARPA or their imaginary number* equivalents will find a way to get some money into this.We currently have lots and lots of brain and spine damaged vets in our inventory these days, and many more will be arriving.All it takes is a couple of smooth talking and optimistic drug reps turned into research shills to tap those resources. It’ll happen.*No, seriously… I don’t think anybody realizes just how big our secret budget for weird science is. It’s really, really big… and I’m for it.",
