Sony Removes PS3 Linux Support; Gets Sued For It

On April first Sony rolled out new firmware for the PlayStation 3 that removed the ability to install Linux on the system by blocking a feature called OtherOS. Now
a class action lawsuit has been filed against the company
for its actions. It doesn’t take an attorney to figure out that they removed features that were a major selling point for the system. As mentioned in
our previous article
, the ability to use an exploit to access the hardware doesn’t mean that every user installing Linux on the system plans to do so. The suit asserts that users had no opportunity to negotiate the System Software Licensing Agreement which is only presented to a purchase after the sale is made. The lawsuit is availble
in PDF from from IGN
.
Who knows where this one will end up. The suit seeks an injunction against the removal of the OtherOS feature as well as compensatory damages. No matter what happens, we still think the removal was a bad move on Sony’s part.
[Thanks Shueddue]

Your analogy of the toaster converted to room heater does not apply here. It’s more like you bought a toaster, turned it into a heater, then the manufacturer breaks into your house and tears it apart in a way that can’t be rebuilt.I have no problem with Sony removing features when they release a new version of the console, but what you fail to understand is that this applies to all consoles EVER sold. Retroactively. You may ask, well can’t you just not install the newest firmware upgrade? Sure, but then you can’t play any games online anymore, another advertised functionality of the PS3. Either way, functionality is reduced after the fact.Also, as far as I know, once a newer firmware is installed, there is NO way to restore the system back to a previous version.",

[Gijs] cracked open his Game Boy and
added some parts
to give him more sound synthesis control. He uses
Little Sound Dj (LSDj)
, a
popular Game Boy program
used to pump out those classic 8-bit sounds. The unit seen above and heard in the clip after the break has an added potentiometer and circuit board. He’s got a few other hacked Game Boys on his site as well, including
an Arduino generating random music
on the handheld.

Mindstorm Rubik’s Solver

It has been quite a while since we looked in on the world of automated Rubik’s cube solving. [David Gilday] built this one using LEGO Mindstorm parts. It uses a computer to calculate the solutions but unlike the standalone
Tilted Twister
, this creation can solve more than one type of cube. As long as the physical dimensions are between 5 and 6 centimeters on a side, the machine can solve 2, 3, 4, and 5 piece cubes. [David] wasn’t quite satisfied with that though. He built
a separate machine to take care of the 6x6x6 cubes
too. See both in action after the break.
Want to see more? Don’t miss
the CuBear solver
developed at Berkeley or the
AVR based solver

Surface Mount Breakout Boards

We got a hold of some DS3232 RTC chips in a 20-pin SOIC package. We’d like to have one that is breadboard compatible for easy prototyping but when we searched for SOIC20W breakout board artwork we found none. We used Eagle to design our own and you can see the finished product above which we made
using the toner transfer method
and
cupric chloride
.
You’ll find the artwork after the break in case you need to make your own breakout board some day. If you know of surface mount breakout board artwork that is freely available please leave the link in the comments for future use, or send it to us on
our tips line
and we’ll add it to the post.
Incidentally, the DS3232 is the same as
the DS3231 used in the ChronoDot
but with the addition of some SRAM. We’ll let you know if we come up with an interesting project for it.
Update:
We added 28 SSOP to DIP artwork submitted by [Paul Dekker]
20-PIN SOIC to DIP
28-pin SSOP to DIP

[bunnie] has taken a few moments to show us how to
turn our Chumby One into a 3g router
. As it turns out, there is an easter egg that allows it to communicate with certain models of 3g dongles. There’s no GUI for this trick, so you’ll be doing most of your configuration via SSH. That shouldn’t be a problem for this crowd though. The
Chumby
One
just got a lot more appealing.

Some OS’s and WiFi dongles don’t actually support AP mode, so even with internet connection sharing you don’t end up getting the same functionality of this. There’s plenty of ways to do this; some require no expenses, some require a $100+ dedicated device. This requires something you might already have; call it a value add to an already fun and useful/hackable device.But I digress. All I know is it was a lot of fun when four people were in my Mini Cooper, road-tripping up the West Coast and xobs (the chumby engineer who did this hack) pulled out his Falconwing (chumby One before it was named such) prototype board and ran some scripts to kick off internet sharing for the three passengers in the car. That was good times! This is just a cleaned up and simplified version of that hack, good to see he’s finally releasing it.So yeah, @mike, it works for that pretty well. :P",

While browsing through flicker this morning, we spotted this interesting image. Two radio controlled cars hooked to Arduinos. What was going on? What is [knolleary] doing with them? We couldn’t find any information so we clicked through to his personal site. What we found was a quite interesting story about how he set up
a race between two taxi cabs being controlled by the Emotiv headsets
for the BBC. Yeah, forget
driving a Rovio around with your mind
. We’re still a bit curious about the two bumper cars in the picture. We can see that his tests were done on a blue radio controlled mini, so what are the bumper cars for? Did any of you catch this on the air? How well did the taxis drive? Was he using the facial expressions or the concentration?

But in the whole theme of the show, they had a piece running through it to see if they could ‘harness’ the brain to drive the taxis. So we focused on the ‘concentration’ side as you describe rather than the facial expressions. You can see some of my thoughts on the headset itself here:http://knolleary.net/2010/04/22/how-i-got-onto-prime-time-bbc-one/#comment-13305The blue Mini was for the original demo to the programme makers (and featured in the programme) before we worked with them to get the taxis hooked up to the system.These bumper cars were done for another colleague how wanted to do a similar demo.I will be blogging about the technology behind the whole thing soon – although much of it will be familiar to hackaday readers.Nick",

[Sprite_tm] dusted off his assembly skills and
managed to emulate a Z80 computer using an AVR
ATmega88. He’s using an SD card in place of the floppy and a 128 KB DRAM chip to handle the memory for the emulated machine. An FT232 board gives him terminal access which he uses for input and display. As you can see, the hardware is much simpler than
building the original
would have been. He makes up for this with complicated firmware. In the end, the emulated core occupies about 2 KB of programming space after he followed the
Z80 Propeller project’s idea
of dividing the instructions into different modules and using a lookup table to access them.

Game Boy Color is notable for its ability to selectively double the CPU clock speed when running Game Boy Color software. The Game Boy Advance series of products originally included this same modified Z80 for backward compatibility. However, this changed with the release of the Game Boy Micro.# In Russia, Z80 and its clones were widely used in Caller ID systems.",

[Shu Uesugi] is filling a controller void that Nintendo has yet to address. He picked up a golf glove from Target and incorporated it into
an air guitar interface
. Give the video after the break a chance, you’ll start to see the full potential of this build about three and a half minutes into it. Using an Arduino, a Wii nun-chuck, and his flex-senor adorned glove [Shu] can play individual notes, strum cords, and play around with sound effects such as distortion.
So come on Nintendo,
the Power Glove
was one of your greatest ideas, where’s our 21st century version? I guess we’ll just have to make our own like [Shu] did. Perhaps we’ll even
build our flex sensors from scratch
.
[Thanks Mark]

Lawnmower Converted To Hoe/scraper

[Torx] wrote this
instructable on how to convert a lawnmower to another useful tool
. We’re not sure what language he natively speaks, but we doubt it is english, so you might be better off just looking at the pictures to figure out what he’s doing. To summarize, he has lowered the mower and reversed/bent the blade to scrape the ground. He has also added thick rubber edges all around to try to keep debris from coming out. You might be wondering why he would need something like this, but the last page sums it up pretty well. We could imagine this possibly getting some use in the garden as well. This one does look pretty dangerous though, so don’t blame us if you cut off a hand or lose an eye to some debris. Then again, a regular lawnmower looks pretty dangerous too.

IEE Clock

"bulb",
"clock",
"tube"

The
IEE clock
looks somewhat un remarkable at first glance. Upon closer inspection though, you’ll find out that there are
12 light bulbs crammed in there for each digit
. The bulbs sit behind a curved lens with the numerals on it. When the appropriate one is lit, it projects the number on the front of the clock. While it isn’t new, it is certainly new to us. It is also interesting that you set the time by rotating the little dial on the top right. While it may be easier to set the time that way, it seems that it would be prone to getting nudged on accident.

[Kirov], a regular reader and one of our most notorious commenters, tipped us off about this
lawn mowing hack
. On one hand we’re wary that this is bait for a huge flame war, but on the other hand it’s a hack that brings a smile to our mischievous faces. By pounding a stake into the center of the yard and connecting a mower to it with a piece of rope, [Korey99] has achieve an automated lawn mower. He tied the self-propelled mower’s throttle bar down to make the machine run unattended. There’s no kill switch or any kind of
remote control for the lawn mower
so we wonder what happens when the rope gets all wound up?

The
MIDI piano instructor
is a tool aimed at those who wish to learn to play piano, but don’t want to take lessons. The LED bar mounted above the keys lights up to show you exactly what key to press and when. We’ve seen this available in some electronic keyboards for some time, but this unit would be able to fit any standard sized keyboard. Check the page for schematics and pictures.

There are some stand alone midi keyboard/piano that does something similar to this but with the LED integrated into the keys. I tried those before and it was much more frustrating than synthesia.I usually just search youtube and watch how other people play for fingering tips. It is pretty hard to find some of the beginner pieces and sometimes the camera pans out right where I had the most problem. =(",

As discussed, this is really just display, and as proof of concept I succeeded, but as far as a teaching system, it requires intelligent software to back it up, and for complex pieces where fingering is far from obvious, it completely breaks down. Not to mention there’s zero indication of note timing.My system took midisimilarinstructions from a piece of software on a host machine that split up a given midi file into left and right hand portions. It could play back a section of the piece, then acted as a filter for the midi controller, blocking the sound of any note that wasn’t the one meant to be played (a feature of some Yamaha pianos). A young student would then only hear a note if they touched the correct key. Reasonably simple staccato pieces worked great, but fat chance learning“like spinning plates”.With real RGB output for each note LED, variable blink and well written software, thiscouldbe a reasonable teaching tool, alerting the user of notes to come with a different color, notes meant to be played at the same time as chords etc, with an on screen display of what the fingering should be. Though really, no replacement for real instruction.I wrote it open just in case it failed miserably (which it did) so for now it works as a major/minor scale and chord display teacher.",

Printable Appendage With Two Joints And Integrated Motors

[Kris Reed]
developed this robotic appendage
as a follow-up to his
original prototype
. He printed it using
Alumide
which is a printable material with aluminum dust mixed into it. [Kris’] design utilizes three gear types; large gear, small gear, and worm gear. The motors are mounted on the middle portion of the assembly and offer an elbow and shoulder type of setup that both rotate along the same plane. We’ve got video of the testing after the break. He makes note that the movement is a bit jerky but can be cleaned up with better motor control using PWM.

I suppose one would consider it expensive, compared to a similar mass of injection-molded plastic from walmart. I just think of the hours/days I saved from having to hand fabricate little gears and a housing at a 0.4mm detail level. On top of that, the ability to dream up anything, draw it up on the computer, and have it in your hand in 10-14 days makes it so worth it. There are some tips and techniques (like hollowing out a model, or making holes in large surfaces) that can make even large models affordable. Take a gander through the model gallery or the shops on the Shapeways website to see what can be done, and what it costs.Personally I think it could be quite useful in the hacker community where so many projects are one-time, custom-made affairs. A lot of projects could look really slick with a designed assembly base to hold the components in just the right locations without resorting to glue or ducttape, or a project box with precise port holes and an imprinted logo.",

[Eric Austin] is
using a Canon 7D with this RC helicopter
to capture some amazing HD video. His success has manifested itself in a company that is now manufacturing these platforms ready-to-use. Take a
look at their blog
to see some of the hardware they’re working on, such as a tricopter and hexacopter photo platforms. We’ve also embedded a video after the break of the unit seen above and the stunning shots it’s able to grab.

Unless you use some thing very small with a cheap lightweight camera, which will degrade your quality and be very unstable anyways. You also can fly a rc heli with winds and keep it stable. If you had watched the video and had any knowledge of rc helicopters he’s using a flybarless stabilization system. This keeps the rc heli locked in place barely any drift even in heavy winds. This RC heli in the video has 3 gyros to keep it stable. He still has a lot of work to do controlling it and can not do both aim the camera and control the heli, but with two people this is easily done. I have a few friends of mine that take aerial photography using a trex 700 and the shots are amazing. also full 360 shots can be taken, but you can’t do that from an rc plane.",

[Robert] at Extremetech was going to write a review of the Emotiv EEG headset but found the bundled software lacking. He decided to write something to really show off what could be done with an EEG in your home. He is now
controlling his Rovio with his mind
. He had already written a new control program for the Rovio, so redoing the same program with the EEG controls would give him a great comparison. If you recall from the
mind controlled TV
, meditating on a single thought can be cumbersome for quick controls. Instead, he used facial expression recognition. Maybe this should be called “face controlled Rovio” instead.

[Zaggo] developed a
printable mecanum wheel
. These are designed to allow a wheeled vehicle to move in any direction. He uses parts printed with a Makerbot along with commonly available bearings, bolts, washers, and nuts.
Download the STL files
need for printing and watch the assembly video after the break. We’ve also included a clip of an unrelated robot project using
mecanum wheels
so you can see what [Zaggo] will have once he fabricates the rest of the of the wheels.
[youtube=http://www.youtube.com/watch?v=ZgrPIcKbykw]
[Zaggo’s] assembly process.
[youtube=http://www.youtube.com/watch?v=RmPbLRDwuGY]
This robot is unrelated to the project. We’ve posted it as example of mecanum wheels in use.

This bright red handheld is [Bacteria’s]
portable N64 console
. We’re beginning to feel a bit saturated with N64 portable hacks, having seen one that
looks like a Game Boy
, another
in a shiny black case
, and yet
another in a white case
. This time around it’s not just the end product, but [Bacteria] has posted a saga discussing the build progress. Check out the
20 videos on his worklog page
. If you’re looking to take existing hardware and put it into a different enclosure you should pour over this resource for ideas you can use.

Bonfire – Interactivity Using Pico Projectors And Cameras

] |
[youtube=http://www.youtube.com/watch?v=O3MZYRAZJNk]
This video
shows a demonstration of Bonfire, an additional interface for computers. It consists of a pico projector and camera hang on the back of either side of a laptop. The projector displays information on the table top and the camera monitors the area for interaction. It can recognize your hand or objects such as a smartphone or headphones and react accordingly. An accelerometer in the laptop picks up tapping (we’d guess you have to tap pretty hard) and there is also support for gestures. This was presented at 2009 UIST and
unfortunately
the published article is
not
available for free
[Thanks for the link Ciflet].
We hope to see this kind of thing, as well as
skin based input
, come to the market some day. Until then, you’ll have to build your own.

Ah, the heady aroma of damp engineers! It’s raining in Silicon Valley, where the
2010 Embedded Systems Conference
is getting off the ground at San Jose’s McEnery Convention Center.
ESC is primarily an industry event. In the past there’s been some lighter fare such as
Parallax, Inc.
representing the hobbyist market and
giant robot giraffes
walking the expo. With the economy now turned sour, the show floor lately is just a bit smaller and the focus more businesslike. Still, nestled between components intended to sell by the millions and oscilloscopes costing more than some cars, one can still find a few nifty technology products well within the budget of most Hack a Day readers, along with a few good classic hacks and tech demos…
(Is that a promise or a threat?)
First order of business was to follow up on a couple of products we’ve covered in the recent past…
We
reviewed NXP’s mbed prototyping platform
in November of last year. While there’s no stunning new revision, the good news is that the
mbed
community is going strong and economies of scale have made it possible to trim the starter kit price from $99 back down to the original early adopter cost of $59.
Additionally, they’ve thrown together a project in just a few days to demonstrate the prototyping ease of the mbed platform. Reading like a checklist of Hack a Day clichés, the demo brings together
Twitter
, the Logo programming language, live web streaming,
servos and an Etch-a-Sketch
. You can read more on the
mbed blog
, or
watch the live stream
and participate during ESC show hours.
We also liked this little breakout board which adds the most essential interfaces to mbed:
MicroSD
, Ethernet and USB host & client. This was something quickly made for an mbed workshop, and while there are no plans to officially productize it, we’re told the unpopulated board might be available through
SparkFun’s BatchPCB service
in the future.
Many readers were put off by the web-centric development approach used by mbed, as well as the lack of a debugger. Another NXP entry-level evaluation product called the
LPCXpresso
provides an affordable ARM development kit from a more traditional angle.
The $30 LPCXpresso boards are available in Cortex-M0 or -M3 varieties and include an integrated JTAG debugger. The downloadable Windows development environment is based around the Eclipse IDE and GNU toolchain. With headers installed the LPCXpresso is
breadboard
-friendly and in fact shares the same pinout as mbed, so there’s an existing ecosystem of hardware to work from.
STMicroelectronics’ STM8S-Discovery made a huge impact
when we mentioned this $7 kit in November
, clearing out distributors in a matter of days. At ESC, ST was showing their new ultra-low-power 8- and 32-bit MCUs with demos powered by a cactus (a variation on the classic
lemon battery
), a cup of warm water sitting atop a
Peltier junction
, and a modest induction charger. (What, no
wind power
?)
A new version on the STM8S-Discovery based on the new lower-power chip should be available within a couple of months, and is expected to be similarly affordable.
(Left: the original STM8S kit that created the ruckus. Right: the forthcoming STM8L kit.)
At the
Texas Instruments
booth, the BeagleBoard XM was being demonstrated, which improves upon
its predecessor
in nearly every regard.
We’re told BeagleBoard XM stands for “extra MIPS,” “extra memory,” (and “extra money,” they joked). The XM does not replace the original BeagleBoard, but will be sold alongside it at a premium price of $179 when it ships in June. The XM includes a faster processor (1 GHz), more RAM (512 MB, and a 1GB model may be forthcoming), Ethernet, more USB ports and improved power protection. The NAND flash is gone, replaced by a MicroSD slot on the underside. The new board is slightly larger but retains the same mounting holes, so it may fit as an upgrade into some existing BeagleBoard projects.
Microchip’s
iPod/iPhone accessory development boards
that we mentioned last month
were on display. Unfortunately it appears one must be signed on with Apple’s “Made for iPod” developer program before these kits can even be
ordered
from Microchip, which really puts a damper on the fun for anyone who might just want to
tinker
.
Drifting further from product specifics and more into hacks and eye candy…
Product teardowns
have become a staple of tech culture. “
Zero-day
” and live blog teardowns of new products are particularly exciting. ESC’s gone one better, making a show of ripping into a product (if a rather esoteric one)
months
before its official release: a high-end Zircon AC wire detector built around a Microchip dsPIC and a bevy of e-field sensors. It’s like engineer pr0n!
National Instruments certainly had one of the most entertaining booths at the event. Rather than passively showing dry PowerPoint summaries and monitors running LabVIEW (their graphical programming environment for engineers and scientists), they instead presented physical demos and projects making use of the software. Some serious, others not-so-serious.
Hacks!
Remember Waterloo Labs’
iPhone-controlled car hack
? There it is! Rather, there it is
minus the actual car,
but with all the essential parts nicely laid out where we can observe the rig in action. At the other end of the booth, one can challenge “
RockBot
” to a round of
Frets on Fire,
not unlike
prior hacks we’ve seen
.
Hack a Day readers might be familiar with Digi International for their
XBee wireless modules
, such as used in Adafruit’s
Tweet-a-Watt
power monitor. Easily distracted by shiny things, we were initially smitten with this addressable LED
matrix
wrapped around their booth; not a product, just something to catch peoples’ interest:
As it turns out, there’s an added bonus hack
behind
the hack. Most of Digi’s booth displays could be controlled and monitored using their own custom
web apps
, so it was a simple matter of walking around with an iPod touch to run the show:
At the ARM pavilion, this “
Speedcuber
” was solving
Rubik’s cubes
in under half a minute. The camera and puzzle-solving logic comes from a Motorola
Droid
. Commands are issued over Bluetooth to a pair of LEGO Mindstorms
NXT
controllers to drive the motors that manipulate the cube.
Macraigor Systems
produces a line of JTAG debuggers…but to be honest, we (and pretty much everyone else passing the booth) nearly missed that fact, as we were all so distracted by their demo application involving one spectacular and elegant
Intel hexapod robot
:
We similarly fanboyed over
Cryptography Research’s
German
Enigma cipher machine
, as it was our first time seeing one
not
under lock and key in a glass museum case:
ESC Silicon Valley runs through Thursday, April 29th, and last we checked one could still
register for a free exhibits-only pass
on the ESC web site.

Free issues of Circuit Cellar magazine and breath mints from Atmel are appreciated perks, but hardly a reason to go in themselves.",

Multiple Buttons And A Pot On one pin
|
Mike Szczys
|
[
"Misc Hacks"
] |
[
"adc",
"potentiometer",
"voltage divider"
] |
[Kevin Fodor] shares his method of
reading multiple inputs on one pin
of a microcontroller. The analog to digital convert function of the microcontroller is used to read a potentiometer but with some careful calculations a resistor network can be built into the circuit that provides a unique voltage value for each button pushed. The only real drawback is that the system cannot read multiple button presses at the same time. Theoretically up to ten momentary push buttons can be used but [Kevin] estimates that only four plus the potentiometer will work reliably.

It also allows multiple button presses etc.Eg: One switch gives 1/2 Vref, one switch 1/4Vref, both give 3/4 Vref, very easy to calculate any switch combination, and every combination of switch is independent.For simpler uControllers, you can use a mux and get 2^(n-1) inputs for every n pins used. (n-1 address lines, 1 data line for the value of the selected switch.) This method is better for uControllers without ADC, or if you want to use less math for faster code.",

I didn’t come up with this circuit, but I was the one that forwarded it to HAD.The resistor ladder is certainly a better way to read multiple buttons with an a/d (if an a/d is your preferred method for digital IO), but it doesn’t allow you to also read off a potentiometer input. Either way, I thought this was a hack in the true spirit of this site.Here’s how I imagine it going: Some guy was probably using a real microcontroller in a real circuit to read a potentiometer. At the last minute management wanted to add some pushbuttons or downsize the uC package for cost.

Eg: Switch 1, 2 are 1/2 Vref and 1/4 Vref, then the pot has a range of 0 to 1/8 Vref. Use math to subtract the value of switches, multiply by 8, and you’ve got your pot reading.

Altair 8800 Pc Case Can Emulate The Original Hardware

The Altair computer is commonly considered the genesis of personal computing and for that reason it has a special place in the hearts of many. [Bob Alexander] brings back the glory of
the Altair 8800 plus a lot of added computing power
. This PC case houses a Core i5 system but the front panel isn’t just for looks. He designed a PCB and resized an image of the original Altair front panel to end up with a fully functioning control interface. In the demo after the break you’ll see that the buttons can be used for power and reset and the LEDs can show random Altair-like patterns. But the interface can also works in conjunction with
an Altair emulator
to perfectly mimic the original Altair experience. This is a great way to sidestep the buyer’s remorse one might experience with
a standalone kit
.

Update: IR Controlled Lighting

[Muris] is back with
another infrared controlled lighting hack
. When we checked in with him last year he was showing off
an IR controlled dimmer module
. Now he’s back with this device that is CFL friendly. Because standard CFL bulbs are not dimmer compatible he’s adapted the project away from dimming and toward switching. The new design still uses an infrared remote but now it can turn two devices on and off again or toggle between them. Our favorite part of the build is that the PIC based device can learn the codes of whichever remote you choose, rather than having to rely on one specific type of remote.

Biosphere Lighting

Sometimes, sitting in a windowless office can drive you crazy. Adding a little bit of life and color can really help. [Gripen40k] did this by
building a biosphere
. He didn’t have any windows though, so he made an LED light on a PIC based timer. What is interesting is what he did with a thermistor. The Cree LED bulb that he salvaged was going to be submerged in the water, so he had to do some workarounds to keep from over heating the biosphere. Read the project log for more details.

Take a few moments and watch this
3 axis rotating LED light display
fire up. The final effect of being an RGB glowing ball is nice, but we’re fascinated with the structure. There are tons of great detailed pictures of the assembly on the forum thread to feast your eyes on. Just getting power to the LEDs was a feat, he passes their power through 6 slip contacts. Parts were pulled from an old VCR and some old fans.

The Personal Mobility Robot (PMR) has a chair for a passenger and balances on two wheels like a Segway. Now the clever folks at the University of Tokyo have added
Wii remote control to the platform
in a full-sized version of
the Segwii
. We understand that adding Wiimote control to anything isn’t exactly groundbreaking at this point. That being said, if using stock hardware can increase the quality of the user interface on something like a wheelchair, while decreasing the production cost at the same time, we’re all for it.

Custom Controllers For PlayStation 3

[Matlo] worked out a way to
use a PS/2 Keyboard and USB mouse with a PlayStation3
. The hard work is handled by a Teensy board, which is becoming
a popular choice with controller hacks
. It interfaces with the keyboard and mouse, translates their input, and sends joystick button commands to the PS3. He is limited to mapping the inputs from a PS3 controller but that is still enough options to work beautifully with first person shooters, especially if you’re used to gaming on a PC instead of a console. If you want to give this one a try, head over to the google code page to
download the source code

And because console games typically run between 30 and 60 frames per second, the delay shouldn’t be noticeable unless it stacks on to the delay of a slow television.I don’t know what the delay is for the Cross Battle Adapter, which is required for the XIM2, but it may be decent compared to the 35ms of XCM’s (the same company that markets the CBA) XFPS. The actual numbers have probably been posted in the PS3 section of the XIM360 community forums.If you only play on the PS3, the XIM1 is the least costly choice, while having performance that is likely indistinguishable from that of the XIM2. Even though the XIM2 has more extensive customization options, buying one ($190) and a Cross Battle Adapter ($50), is overly expensive if you are not also using the XIM2 on a Xbox 360. By comparison, the XIM1 option costs $40 or $50 to build yourself, and $80 to $90 to buy a pre-constructed model, coupled with a $10 adapter.",

[W1VLF] is on a quest to communicate over long distances with a 9 kilohertz transmitter.
He built this giant coil
with that in mind. A round concrete form was used as a base and wound with magnet wire by hand. We’d recommend building
an automated winding device
, but this method seems to have worked. Operating at 50 Watts on the air-core coil at 8.97 KHz he was able to pick up the signal at a distance of 5 kilometers. It’s not breaking any overall distance or portability records, but on a project like this the quest is where the fun is at.
[Thanks Drone]

"content": "The length of the wire in the coil is unrelated to the wavelength. When W1VLF says “resonant” he means that at the specified frequency, the reactance (imaginary component of the impedance) is zero. If your antenna is too short for your specified frequency, the reactance will be negative (capacitive reactance) and so you can add an inductor of equal and opposite reactance to reach 0j ohms. It’s not the case that the wire length in that inductor is related to the wavelength, though. You just solve the equation 1/(w*C) = (w*L) where C and L are the inductance and capacitance, and w=2*pi*frequency. That’s what he’s doing when he measures the coil as being 168 milliHenries. The real component of the impedance (measured in regular ohms, not imaginary axis ohms) has two parts: the loss from the wire measured as a resistor at DC (where he said 60 ohms for his first coil), and the “radiation resistance” which is also expressed in ohms, and shows what gets “lost” from the antenna by being radiated into space. Assuming reactance X=0, the efficiency is calculated just like a resistor divider, with some power being lost in the coil as heat, and some being radiated. Efficiency = Rr/(Rl+Rr). The Rl=60 ohms is quite large, since the radiation resistance of such a drastically shortened antenna is probably in the milli-ohm range, so his efficiency is probably on the order of 1e-3/(60+1e-3) =~ 16e-6 or about -110dB of loss. So (assuming the milli-ohm radiation resistance guesstimate is OK) his 50W in actually radiates around a milliwatt.Seehttp://en.wikipedia.org/wiki/Antenna_%28radio%29#Resonant_frequencyandhttp://en.wikipedia.org/wiki/Antenna_%28radio%29#Efficiency",

This isn’t a specific project, so much as a pointer to a budding new site.
Puppet Circuits
is the project of [Raphael Abrams], one of the co founders of
NYC Resistor
. As you can probably guess, he has been posting about the circuits he uses in his animatronic puppets. I faces all kinds of problems since may of the systems are to be worn and have to endure some pretty rough treatment and still perform well. Very interesting stuff to read about.

RFID Immobiliser

[andrew_h] has put together this slick anti theft device for his car. The
RFID immobiliser
is used to keep the car from starting unless you swipe an RFID tag. Depending on how well you hide it, and how well the person stealing the car knows you, they would have no reason to suspect that they have to swipe the tag. Even if someone steals the car while it is already running, they won’t be able to re start the engine if they shut it off. As usual, schematics and PCBs are available.

Cell phone chopper control
Control your tiny inexpensive
helicopter with a Nokia N900
. The chopper uses an infrared remote control, just like a television. Getting this to work was just a matter of figuring out the IR commands and writing an app for the phone to spit them out.
Fade to black; inconspicuously
Lost interest in your TV-B-Gone? Give it one last whirl by
throwing it inside of an old iPod
case. The dock connector hole is just about the right size for the LEDs and
the kit
fits nicely in the old 3G type iPods. With this kind of disguise it should be a lot harder to spot who’s messing with those TVs.
Surf your way to a cleaner house
This guy uses a roomba to clean his floors. The Wii balance board lets him lean forward and back to
surf the little bot around the room
. This seems a little more exciting than the exercise programs the board was originally designed for. [Thanks DXR]
G1 gamepad
[Tobias Weber] built a
gamepad for the G1
Android phone. He used an old Atari control, cut out two buttons and the d-pad, and glued them in a housing to fit the G1 keyboard. Each presses a button on the phone’s keyboard which can be mapped through the emulator software.
Social power monitoring
Here you see a very small portion of the
power meter installed in a Cafe
at UC Berkeley. It shows the energy usage for the building, separated into categories such as lights, power outlets, and coffee machines. This lets students know how much juice they’re draining by plugging in their gadgets. The color bar uses 93 ShiftBrite modules controlled by an Arduino.

Finally a guitar that all of the arcade gaming geeks can jam with. [Mike Davenport] sent us his
8bit arcade based guitar
for his senior project. Details are a little sparse if you intend to build you own at the moment, but he does mention the basics: such as it uses an
FPGA
for logic and function, the strings and joystick modify pitch, it has selectable waves and other parameters, and even includes save banks! Check out a video of him
playing street fighter
rocking out after the break.

The
Alex eReader has been rooted
. This
little handheld
was the belle of the ball at CES 2010 when it came to eReaders. Now that is has been released into the wild it takes its place next to
the heavy hitters
that have
already seen root access
. If you’re unfamiliar, this device boasts a six-inch e-ink display and a 320×240 LCD touchscreen interface. Now that you can make it do your bidding, what are your plans for the $350 tablet? Let us know in the comments.
[Thanks Richard]

Apod walks
! If you recall,
last year we discovered Apod
, the creepy lifelike hexapod creation made by [Zenta]. At that point in time, it basically just shifted around nicely but didn’t do much walking. Well, [Zenta] has been hard at work since then and now Apod is fully active, walking, running, and serving drinks with smooth motion. Want to learn more about how his inverse kinematics work? Check out
this thread
.

40 MSPS Digital Oscilloscope

"atmega162",
"cpld",
"oscilloscope"
] |
If you can fabricate single-sided circuit boards at home
you can build this digital oscilloscope
. It uses mostly through-hole components with just a couple of surface mount chips to contend with. An ATmega162 handles the hardware end of things with a CPLD used to manage the sampling rate. Data is displayed on a 240×128 LCD display which will be the most expensive component to acquire. It’s still a lot cheaper than buying a commercially available oscilloscope, even if you
get a base model and hack it to unlock all the features
.
[Thanks Juan]

Rendering And Blendering In A File Cabinet

The Blender Foundation has
just received a new render farm
. It came in the form of a four-drawer file cabinet something akin to the popular
Ikea clusters
. Each draw holds four motherboards, power supplies, and hard drives and the whole cabinet will eventually add up to a 16-node cluster. Join in on the geeky excitement by watching the delivery and unpacking video after the break. We love it when
organizations share the details
on the hardware they use.

"content": "@MrWazoo,Simply placing a fan in the bottom of the cabinet and putting the cabinet in an air conditioned room doesn’t ensure adequate cooling. When you’re talking about a stack that’s likely going to draw over a kilowatt of power (assuming a very low 250W per drawer), you have to be a lot more careful planning the airflow.For example, if they place four drawers of equipment in this cabinet, the bottom drawer will get fresh air just fine. But it will exhaust heated air out the top. The next drawer up will be sucking heated air in, and exhausting even hotter air. When they get to the top drawer, it will be exactly the same as if they placed a 750W heater beneath their PC.Commercial rackmount equipment addresses the issue by drawing fresh air in from the front of the cabinet and exhausting the hot air out the back like a chimney.They might be able to reduce some heat by sharing power supplies. There’s no reason to have four independent power supplies (each producing some amount of waste heat) when they could use one larger supply to power all four boards in a drawer.I think they’d be better off if they planned for water cooling. In a liquid cooled environment, they could transfer the heat to radiators located well away from the cabinet and away from each other. They would still need the airflow through the stack to cool the rest of the components, such as the RAM, the north and south bridges, and the hard drives, but the heat management problems would be much lower than they would be trying to use airflow alone.And while the Blender logo grille at the top is extremely cool looking, I’m thinking they’ll eventually have to replace it with an actual duct to vent the hot air out of the building, at least during the summer months.John",

When continuity is your prime concern and you have unique services that cannot be split across tons of redundant low-cost machines, then yes, you’ll want a nice Supermicro/IBM/Sun/whatever machine to run your stuff on, splurge on RAID with hot-spare, go for redundant ethernet uplinks, multiple PSU’s with seperate power-feeds; the works.When you have a problem like rendering, where missing a node for a while only results in a frame that needs to be re-rendered ‘sometime today’, or have other problems/services that can be split across multiple machines in an efficient/redundant manner; then it’s rather normal to go for a solution like given here; much like Google did when they started out (and they still do, for a great deal).Ofcourse, Kris, next time we’ll make sure to ask you for a good bunch of technical consultancy first; sorry for ever have done things another way than ‘the right way’.",

So I did and have no regrets doing so!The hole in the top was required in any case; dremeling it circular or ‘circularly lobbed’ wouldnt have mattered much. I was gonna leave it entirely purple (the cabinet’s original color) but due to an accident in handling the panel it got damaged and I decided to go ‘all the way’ and paint it in the color that the logo would normally have (or at least as close I could find it).Disclaimer: i work at an ISP; all I know is server-hardware. Yes it’s nice; but we didnt need IPMI/raid/triple-gbit/ECC-memory/etc. Just keep it simple; use off-the-shelf hardware. Hardware WILL fail; best have it be cheap hardware and never have one node be critical to your entire operation. When each node is identical to the other; who cares about one breaking down. Also, the biggest reason server hardware is so expensive is the un-standard form-factor. When you try to squeeze a machine into a couple of inches; require it to keep itself cool (with no standard coolers fitting) and also require a more expensive PSU (high-power, small-form-factor), then yes, you’re going to pay top dollar… err.. euro.",

"content": "…continued from previous post:The cooling is taken care of in the sense that the big fan takes care of dumping the heat generated by the cabinet’s processors quite efficiently out the top into the cabinet’s environment. As long as you keep the room reasonably cool, things should be fine. Also, thermal management and monitoring are being used to mitigate problems (as do built-in safeguards in modern motherboards/cpu’s).The cabling has been pre-done; each drawer has a total of 6 ethernet-cables (4 for direct use; 2 ‘just in case’) and one power-cable that leads to a 4-way socket-block that connect to the PSU’s. They’ve been wired and bundled in such a way that each drawer can fully extend for it’s full length out of the front of the cabinet while the boards are kept powered on. Only issue is cooling, then; but four boards seem to keep cool well enough on their own when exposed to open air (thermal venting).The power-consumption on 4 boards , in idle, was around 1.6Amps @ 220V with 80%+ PSU’s. Under load, it moved to about 2.2A , tops. That’s about 2000Watt of heat production to remove from the cabinet and room; luckily we have an option of venting to/from a cool concrete hallway right next door; as well as an (as of yet) optional air conditioning unit (sadly not a split-unit, but at least it dumps hot-air out the back through a hose)As far as performance goes: yes, GPU rendering would’ve been wonderful, if it’d have been anywhere close to production ready at this point for the Durian project (http://durian.blender.org). As we say in dutch ‘Je moet roeien met de riemen die je hebt’ (you gotta row with the oars you DO have).",

Also, upgrading with 3 slots still empty should be more cost-effective, too.Given that rendering is also rather memory-intensive (textures, light-maps, etc), it sure won’t hurt to have a bit more bandwidth available in that department.Also; note that putting it in a filing cabinet was done on purpose; a hat-tip to the brave person who went before us; the creator of the Helmer Cluster.",

So at idle the systems haven’t all the power savings on, or the load isn’t so big, or some other reason I’m unable to figure.And a pity you found no 1156 boards and had to go with 1366 socket, they should do fine with 4 sticks of 2GB, the CPUs are even lower power but with similar performance (or better when running one process, like non parallel parts of Blender).

Apple IIe Twitter ticker

A hand input bootloader and a custom communications protocol are what bring the
Apple IIe Twitter ticker to life
. [Chris Yerga] bought the decades-old machine for $20 at a flea market. Having just completed his
TweetWall
he decided to adapt the idea for the 1 MHz machine. He manually input a 50 byte bootloader that would let him dump programs into memory via the joystick port. From there he rigged up
a connection with a USB FTDI cable
. Now the images and text are processed by a modern-day machine and fed to the Apple IIe at 3600 baud. See this in action after the break.

This
video game controller
is a factory fresh VW. Much like the
racing simulator from earlier in the week
, the video game data is being displayed on the instrument panel. This takes us to a much higher level now because control for the game is taken from the car’s
CANbus
using and
ODB-II
connector. If you don’t speak in automotive jargon, that means that the sensor readings from the steering wheel, shifter, and pedals are being picked up and exported as joystick commands to the PC running the driving game. The only place the experience uses a substitute for the real thing is the sound, which is being played through speakers instead of emanating from under the hood. Looks like you just need to add a projector and screen to your garage in order to turn it into the hottest new gaming device.

"content": "This isn’t a good idea for various reasons.1 – Vacuum operated brakes. Once the vacuum is gone, you have a rock hard brake pedal. If you happen to have a vehicle with electrohydraulic brakes, then you will completely deplete your hydraulic accumulator in about 20 brake applications, and once again, rock hard pedal, but with the added inconvenience of a long recharge time.2 – Power steering. Obviously, you don’t have it. However, on many vehicles, excessive turning of the wheel will cause air to be pulled back into the steering gear, which will result in power steering system growling for a while after you restart the vehicle.Worse yet, on some power steering pump designs (such as those used on many Fords), after you turn the wheel back and forth about 5 times, the steering pump will begin to regurgitate all of your power steering fluid out of the fill cap, because the fluid is being forced out of the steering gear and is replaced by air. A nice, oily mess.It’s a nice idea, but probably not a good idea to do this to your car if you plan on driving it in real life as well.",

Playstation 2 Controller To PSP Adapter
|

[
"PSP Hacks"

[
"controller",
"playstation",
"psp",
"tv out"
] |
[TokyoDrift] built an adapter that allows you to
connect a PlayStation 2 controller to a PlayStation Portable
. It’s a bit different from similar hacks as this adapter doesn’t require any hardware alteration to the PSP or the controller. To do so, a plug-in is used on the PSP firmware side of things. The adapter then makes use of video out and PS2 controller extension cables, along with an ATmega8 microcontroller to handle the signals between the two devices. We posted a picture of the guts because we like that king of thing but the finished project is nicely housed inside of a project box. See for yourself in the video after the break.
If you liked this hack, check out [TokyoDrift’s] method of
using a mouse with a PSP

Flux-cored To MIG Welder Conversion

[Rob] sent us some information on how
he converted his flux-cored welder to a metal inert gas welder
. He used a piece of DOM tubing as a collet with a side inlet tube that he uses to inject carbon dioxide. The gas is sourced from a 12 ounce paint ball CO2 tank and it looks like there’s a valve right at the junction with the collet. We wonder how long it would take to tear through one of those tanks, but if you’re not doing a lot of MIG welding this saves on the upfront cost of buying a separate setup.

What really empties a CO2 tank in a hurry though is using it to drive air tools.If you really want to get cheap CO2, the best way I’ve found is to buy used, expired CO2 fire extinguishers at auction or yard sales. Just make sure they’re still full and mount them sturdy upside down for gas. I’ve gotten an entire full CO2 tank and 15 lbs of CO2 for $15.",

This is my main rig, a Lincoln 135 w/ mostly co2. but it does mix and fluxcore too.If you want to save money, flux seems to work out cheaper per inch of weld. With no shielding gas bottles, hydrotests, or tank rental fees, flux core is used in production welding whenever possible, even realizing that you’ll have to chip off the slag. You also can’t do the really thin stuffIf you are learning to weld, get an auto-darkening helmet. They’re cheap nowadays and it will save you hours while picking up the needed base skills.",

You are right it is used primarily for Aluminum as AL is has high heat dissipation so you need more heat input.

[.ronin] built an
all-in-one WiFi and Bluetooth sniffer
. He used a Nerf rifle as a base and added two Pringles cantennas, a tablet PC, and other various bits to tie it all together. Now he wanders the streets, explaining the device to bewildered passersby. After
showing the device at CarolinaCon 2010
(here’s a
PDF of his presentation
) he stopped by the mall nibbled about 250 Bluetooth devices using
SpoofTooph
. The software is running on a Fujitsu u810 tablet and he’s making good use of
Backtrack 4
during his wireless adventures.

Pringles can: original purpose – holding chips, new purpose – accepting signals. Nerf gun: original purpose – shooting darts, new purpose – sniping signals. To me, that sounds like re-configuring a system to function in ways not facilitated by the owner or designer, so yes, it’s a hack.If you don’t like that definition of a hack, open your own blog where you post examples of what you think hacks are and show us how it’s done so you can feel special about how much more elite you are than us lowly wannabe hackers.",

But seriously there is no way to build wifi antenna at home without equipment costing more than home, and all those who try just know nothing about RF and producing infective solutions since there is no such luck to get mm precision + electrical length does not equal to physical and if antenna resonance on wrong frequency it only 5% effective (funny but this is what you usually get from all personal/home class hardware)",

This is the
fourth generation MIDIbox sequencer
which has a features set that’s several screens long. We’ve embedded the teaser video of this 16-track marvel after the break. You can use it via a traditional MIDI connection or with USB. Standalone Ethernet features are also in the works. It’s
fully documented
and you can etch your own PCB if you’re brave but it might be easier to get in on
the group PCB buy
if you just have to have one of these. There’s no all-in-one kit, but that will just make the taste of success sweeter once your soldering iron cools down.

I have been using MIDI for 20 years and sequencers are a pain. They are a very unfortunate pain but most work decent enough if you have instruments that will lock on the same ppqn BUT computers have made this SO much easier graphically that I really can’t see too many uses for actually building this except for proof of concept and a shiny “brass bollox” soldering iron. Some folks said it is useless and maybe not hackworthy and they DO have points. You can get old hadware sequencers that do all of this and much cheaper and change their timing resolution etc for pennies on the dollar for the build cost of this thing. Your standard 10 year old laptop can run loops around this in terms of interface and is a cost effective method of a portable sequencer. It is great that many of you builders have cutting machines, laser etchers, multimode/multivoltage selectors and ice cream that makes ice cream lol, but it isn’t common man materials by any means and I think some folks feel disenfranchised by that. I personally felt alienated at many projects on here but that is what hackers do: they make do. If these projects seem prohibitive in scale or cost or wife-glaring, then I would suggest circuit bending to those folks for a quick fix and a small budget. So yeah, this is a really cool thing to see without “Korg”, “Alesis”, or “Roland” on the front of it, but seems a little backwards in logic if you are really wanting to sequence right now lol. sailormouth has a lot of info on injecting 555 timers into the bends and using one as a sequencer for other machines.",

If we want to move forward and prove that our power as individuals is greater than those in power (politically, economically) we need to make sure to be inclusive and respectful.Big corporations and the scientific community have used gender roles and stereotypes to sell us crap and exclude new ideas. It’s time to stop quantifying arbitrary characteristics and realize that all humans are valid regardless of sex, gender, orientation, bodily ability or cultural background. Avoiding attaching negative values to words like “bitch” and “pussy” are a huge part of this.Hackers need to stop augmenting the status quo by selling their ideas and values.

"content": "@tehgringe – Damn Bible thumpers. There, now it’s out of the way. Maybe we can elevate the intellectual level of this discussion.@ Those stating the real lack of need for a sequencer. Many of you have never really understood how flexible MIDI really is, and the vast majority of the commercial product’s barely even scrape the surface of what a motivated, and innovative person can do with simple MIDI trigger’s. Using this sequencer as the basis of a project, I’m sure I can come up with several method’s of automating an entire workshop, or even simple robotics into doing pretty much whatever your little heart desire’s. Try doing that with a software package that require’s actual synching to even register a MIDI device on the end. If you want a dumb trigger box, which is what a sequencer is, this example is a great stepping stone to get there. MIDI is by far the most stable and robust timing signal protocol to use for the hobbyist.Like it was stated before, you guy’s are not even aware of what can actually be done with MIDI. You are looking at it purely from a musical standpoint, which sequencers have outlived their usefulness. You are missing the rest of the picture, which is what hacking is all about. Making thing’s do something that they are not originally intended to do.This guy’s project was his own, and he did a great job on it. Commend him for the level of dedication to having something done the way he wanted it done, and following through with it. Learn from what he learned, and what he developed, and add it to your project’s if you see it being usefully to you. If not, note his achievement, and move on about your business.Bickering over crap like that doesn’t make you into someone that will get you far in the world. The world has plenty of asshole’s already.",

Spice up your next house party with this
diy foam machine
. [Stephen Martin] posted his PDF plans for
version 1
and
version 2
of the device. It seems the deciding factor on the machine is the type of fabric screen used to create the suds from a bubble bath liquid. This is the reason he’s got two versions. They share a lot of the same components (especially the expensive ones) but the first version is easy to swap out different fabrics and the second is a more permanent installation. In the end, we’re looking at a sump pump feeding foam to a fabric net that is attached to a blower. This will be a nice addition to
that fog machine you built
last fall.

We have the best luck using no-tears bubble bath and adding a considerable amount of glycerin. The higher the ratio of glycerin the longer the bubbles will last on their own, and the foam will be less ‘wet’ and more ‘sticky’. If you overdo the glycerin it will stop bubbling as much and become gooey so there is a definite balance to work out.Finally, it’s important that the water you mix it with is HOT as you can get it. This allows for more complete mixture and better blending between water, soap, and glycerin. It works best if it is mixed before being pumped, so we typically have a resevoir made from a horse watering trough which we continuously fill with a hot water tap and the soap mix.",

VFD As A Sound Amplifier

"vfd"

[Alessandro Lambardi] had some vacuum flourescent displays that he pulled from junked VCRs. His latest project is an experiment to use one of the VFDs as a headphone amplifier (
Wayback Machine Cache
). This means he’s trying to use them as vacuum triode amplifiers, aka
vacuum tubes
. He did get it to work but as he suspected, the output is fairly low power. It may be possible to use this setup as a preamp and
build an actual tube amp
to use along with it.
Update:
Thanks to [Fallen] for mentioning that
we’ve covered this concept in the past
.
[Thanks Muris]

Android,
on the iPhone
? We’ve covered
iPhone Linux
before… and if you look back, we mentioned the possibility of porting Android to the iPhone (even way back in 2008!). Well we are proud to announce that
The Future is Now
! The details are a little slim so far, but the iPhone is seen running a stock Android 1.6 install (Donut), and has support for Wifi, GSM networks, and even uses openiBoot to dual boot to the regular iPhone OS if you aren’t particularly committed. Right now the developers are considering it an Alpha version, and have provided all you need to perform this particular brand of Cult of Apple
heresy
. One catch though, the developers say that they only have it working on the 2G models, so sorry all you 3G(S) folks (for now). Dont get too down, and keep an eye open, something like this is bound to attract new talent to push the movement.
Anyone out there with a 2G and some free time? We would love to see some users showing off Hackaday on their hacked up iPhone!

WaitingForFriday’s [Simon Inns] is quite possibly the USB interface and PIC master. This week he let us know about his
VU-meter repurposed as a computer performance monitor
using a PIC18F2550 and his
open source USB Generic HID communication class
. With PWM the meter’s needles and RGB LED can be accurately set and even dampened for CPU usage, network usage, HDD utilization, and even memory usage. Oddly enough, in his software we didn’t find the ability to use the device as a VU-meter – go figure.

"captcha",
"color code",
"resistor",
"resisty",
"wordpress"
] |
[PT] tipped us off about a new way to screen bots from automatically leaving comments.
Resisty
is like CAPTCHA but it requires you to decipher color bands on a resistor instead of mangled text. This won’t do much for the cause of
digitizing books
, but if you can never remember your color codes this is
a good way to practice
. Resisty comes as
a plug-in for WordPress
, add it to your blog and for a geek cred +1.

I got the meaty bits taken care of, but I’m not motivated to glue it together into a script tonight.I used wget 10 times to get a sample of the resistor images.I found that the color of the bands were located at the following pixel locations:45×4080×40110×40150×40Ran those through ImageMagick like so:convert png:resistorImage.php.3[1×1+45+40] txt:convert png:resistorImage.php.3[1×1+80+40] txt:convert png:resistorImage.php.3[1×1+110+40] txt:convert png:resistorImage.php.3[1×1+150+40] txt:That spits out the correct RGB codes like so:$ convert png:resistorImage.php.3[1×1+45+40] txt:# ImageMagick pixel enumeration: 1,1,255,rgba0,0: (100, 50, 0,255) #643200 rgba(100,50,0,1)$ convert png:resistorImage.php.3[1×1+80+40] txt:# ImageMagick pixel enumeration: 1,1,255,rgba0,0: ( 0,255, 0,255) #00FF00 lime$ convert png:resistorImage.php.3[1×1+110+40] txt:# ImageMagick pixel enumeration: 1,1,255,rgba0,0: ( 0, 0,255,255) #0000FF blue$ convert png:resistorImage.php.3[1×1+150+40] txt:# ImageMagick pixel enumeration: 1,1,255,rgbaSo the outputs are nicely machine readable into RGB values.From there we have to match the RGB codes to the form, the form values resist1,2,3,4 are set to match the number shown in the slider. These don’t change so we can swipe them once and get the 0-9 values.Then we actually have to calculate the resistance and populate the hidden ohms and perc values using the code in the JS function getResistance().resist = parseInt(resist1 + resist2) * Math.pow(10, resist3);document.getElementById(‘ohms’).value = resist;document.getElementById(‘perc’).value = resist4;Now that we have resist1-4, ohms, and perc we can then fill in the standard WP form values and submit our post.I wonder how it can be made better. Maybe using an actual product image of a resistor, so take a catalouge image of a 47K Ohm resistor and then show that to the user. Rotation of the image and varying the angle or width of the bands.Its a neat and educational CAPTCHA. I had fun roughing out a script to get around it.Cross posted at the original site, just for my ego.",

The continuing battle for smallest console-made-portable continues with
this N64 portable hack
. Unlike the
last
two
that we saw, this version opts for an over-under rather than side-by-side control scheme. This results in a small overall size, but because this thing is a thick brick we wonder if playing for hours would just leave you horribly mangled and crippled from the elbow down. [Bentomo] may have thought the same thing because he also built a breakout connector to use the original controllers (and play with more than one player on that tiny screen). If you’re a slave to the build details like we are check out
his build log
and the video after the break.

Replicating Connectors By Machining PVC

"hang on tank",

"PVC"
] |
[Alex] bought a hang on tank filter for his aquarium. Unfortunately it was made for a different water level than he was using and didn’t have the ability to adjust that he needed. Add to that the non-standard pipe sizing which compounded the problem by making it difficult to extend the intake and output tubes. He overcame this by
machining PVC pipe to match the stock connectors
. After turning the PVC on a lathe he added a neoprene o-ring and painted the assembly black. The new connector allows standard size PVC fittings for easy changes in the future, and it keeps his turtles healthy and happy.

We’re all for putting a GPS where it doesn’t normally go, but we’re not sure
[Roberto’s] version
* is the best of locations. Take for example
[Jair2k4’s] GPS
. It doesn’t block out 50% of his vision of the road and the impending accident in front of him.
Regardless, the solid aluminum and seamless mounting really does make it look like part of the car, and props to him for making it ‘hidden’ when he’s out of the car to try and prevent thieves. But there are cheaper, easier, and dare we say
better solutions
out there.

Gently Stroke This Drum

The silent drum
is played with your hands. It acts as a midi device by analyzing the movement of the rubbery black drum head. As you can see in the photo, one side of the body is clear and the other is white. A light shines up into it to boost the contrast and a camera picks up the black head as it moves past the white side of the shell. [Jaime Oliver] has provided an interesting look at the
analysis method
used with this instrument and there’s also
a system of notating a composition
for future performance. See and hear it played in the demo after the break.

Build Your Own RFID Reader
|

[
"Security Hacks"

"ATmega32",
"cornell",
"reader",
"rfid"
] |
We asked for it and our readers delivered. [Klulukasz] left a comment pointing to this
diy RFID reader
that was a final project in 2006 for a class at Cornell University. It is well documented and includes not only a schematic and code, but an explanation of the design considerations used during the build. The project uses an ATmega32 and the parts list priced out at about $50 at the time. There were plenty of responses to the
RFID spoofer post
pointing out that there are readers available for $40, but we want the fun of building our own.
A bit more vague with the details but no less interesting is this other
simple RFID reader design
. Thanks to [Chuck] for his comment which pointed to that link.

Toaster Web Interface

Within a ten-hour window [Wes Brown] threw together this
toaster with a web interface
for one of his classes. He sourced the
WIZnet embedded webserver
for the project but this could be pulled off with
a homebrew webserver
as well. When you point your browser to the correct address you’re greeted with images of bread that have been charred to various degrees. This greatly complicates the act of making breakfast while at the same time presenting a possible fire hazard. Check out the video after the break.

Augmented reality is a pretty neat thing but we don’t want to live our lives staring at a smartphone as we walk around. [F00] didn’t either so he built these
augmented reality glasses
. You can see a hole in the middle of the glasses where he added a webcam. The camera captures the image in front of you, processes it through augmented reality software, then sends the image to the wearable display that makes up the body of this hack. Integrate this into the
head-mounted Linux hack
and you’ll be able to ride your bike around the real world with your blast shield down instead of being
tethered to your trainer in a virtual universe
.

The Droid, even with its measley 550 MHz processor and paltry 512 MB of RAM, still manages realtime video. Realtime video to a set of glasses is not a problem. Sure – he’s limited to a lack of 3d vision, but reaction times should not be changed in the least bit. If you’re expecting realtime metadata to appear, that’s still a couple of years off.

Makerbot Clone

[
"cnc hacks"

[
"3d",
"extruder",
"makerbot",
"printer"
] |
This
table-top extruder
was modeled after the
Makerbot
. Instead of laser-cut wood this is built from acrylic, uses salvaged rods from laser printers, some inexpensive stepper motors, and a homemade extruder. All said and done, [
Peter Jansen
] figures this build came in somewhere around $200-300. It may not look as nice, but at half the price of the Makerbot base kit you also get the fun of building from scratch. Hopefully your fabrication skills are up to the challenge. If so, you’ll be
printing useful items
soon enough.

Arduino RFID Spoofer

"rfid",
"spoof"
] |
An Arduino, a spent roll of toilet paper, magnet wire, and a few passive components are what’s needed to build this
RFID spoofer
. It’s quick, dirty, and best of all, simple. However, [SketchSk3tch’s] creation is not an RFID cloner. You must already know the hex code of the tag you want to spoof. That may or may not be as easy as using a separate tag reader.
We’ve seen some very simple
RFID tag
concepts. What we want is a DIY reader that is easy to build from cheap and readily available components. If you’ve got one, make with the details and
tip us off about it

You would need a uC capable of generating the 125 KHz while simultaneously monitoring the power going into the LC antenna circuit and decoding any changes that would indicate the presence of a second tuned or detuned circuit drawing power off it. It’s quite a bit more complicated than emulating the card, which was designed to be simple and dirt cheap and not really worth the effort when a turnkey solution is available.This card hack is kind of cool mainly because there is no pretense of it being practical, and you could theoretically use it to clone a card, which with the read only cards is generally assumed to be impossible.",

"content": "@skinnerAs klulukasz said there are a ton of possible combinations and it would take a long time to go through them all. I’ve heard though that some companies buy batch of cards that end up being sequential. If that’s the case, then if you can just read one card from a location, then you could work from there. In many cases if you have one working ID (the one you were able to read) you don’t need any more, but in other cases different cards give access to different locations. So, if your ID doesn’t work for a door, you could try several IDs around the one you’re using.@LorenzoI’m not sure an Arduino is fast enough to emulate a 13.56Mhz card (it’s about100 times faster). I’m curios if this could be done with a Maple (Arduino clone using an ARM processor) or with a Butterly Uno (FPGA that you can program using the Arudino stuff). I’m guessing you could do something similar to the 125KHz one, I’m going to try it with my Maple and see how it goes.I’d love to see a cheap DIY reader. The Propeller one is really cool. It would be awesome to combine that reader with this emulator. It would be even cooler if you could do it the reading and emulation all on the Arduino, which I bet you can (I’m sure you could do it all on a Propeller).By the way, you should be able to modify the sketch so you can also hook the Parallax reader up to it for reading (which would then effectively make it a cloner). There were a couple of reasons I didn’t do this. First, I wanted to keep the project really simple so others could build on it and add whatever they wanted. Second, the Parallax reader reads EM4100 tags. It does read a lot of tags, but I was hoping to figure out a more generic reader, because you should be able to clone more tags using it.By the way, when I picked up my reader a couple of weeks ago it was on sale at Radio Shack, the marked price was $49.99 but when they rung it up it was only $29.99. It looks like it’s been removed from their website so I think they’re closing them out.",

One part remote control car, one part camera, and two parts flash make up this
all-terrain camera
. The folks at Burrard-Lucas photography put together this guerrilla device to capture images of some of the world’s more dangerous wildlife like elephants and tigers (oh my!). This project furthers our opinion that
great photographers need to be great hackers
to get the shots they want.

Alright class, quiet down and open your books to the chapter on Manchester Encoding. [Brian J Hoskins] did just that when building this
RC5 decoder
. This protocol is commonly used in television remote controls. You use them on a daily basis, don’t you think it’s time you understood what’s going on? Check out his writeup and learn the dark art of invisible light communication. Or just skip the learning and
follow our how-to
.
[Thanks Tim]

You will not find published documentation on RC-6 on any manufacturer site.

Egg Incubation Chamber

"attiny26",
"dc18b20",
"incubation"
] |
[Mazomen] left the expensive ready-to-order options for others and built his own
egg incubation chamber
. It keeps the eggs warm and happy in a Styrofoam lined box. Temperature regulation is handled by an ATtiny26 microcontroller in conjunction with a DS18B20 temperature sensor. When the temp drops, two 60-watt light bulbs in the chamber above the eggs are turned on and the air is circulated with a small case fan. If you’ve already made the switch to
automated vegetable growing
this project will make your chicken raising easier as well.

Without a fan the air in the unit forms into “layers” with cool air at the bottom and hot air at the top. This makes it difficult to get good regulation of the air temperature and humidity. With the fan it doesn’t matter where the heat source is. However, putting the heat source on the top gives you a degree of safety. If the fan fails the unit will get hot on top but the egg chamber will be cooler. Since eggs can tolerate being cooled while incubating (mamma hen gets off of the nest occasionally) they are more likely to survive. Having the heat source below means the eggs get baked if things go wrong.",

It works great at a fraction of the cost of a pro unit. When I built mine I built it big enough to accommodate a “egg turner” (actually an egg tilter – about $40 – Google it) so I wouldn’t have to turn them by hand. In addition I would recommend a way to monitor the humidity since it’s important too. Wal Mart sells a little temp/humidity unit for about $12. The suggestion above for an automatic humidity control (Honeywell HCH-1000-002) sounds like a good idea to implement but I’m not sure how to implement the actual control.

[Robert Pickering] shares his
automated guitar pickup winder
with us. He built it for his senior project at Old Dominion University. Two stepper motors are used to wind the magnet wire around the pickup hardware. The unit is PIC based and about six minutes into the video (embedded after the break) you can see that he used wire wrapping for this build. Curious, one of the comments on
our latest Hackaday Links
mentioned that wire wrapping was rarely used anymore, but here it is anyway.
We especially like the limiting switches he’s using on the traverse mechanism. There are momentary push buttons on either side of a carriage which are depressed when a drywall screw in the sides of that carriage hits them. This makes for very easy calibration because the screw can be raised or lowered with just a bit of screwdriver work. Well built and documented, we’re sure he’ll get some high marks on this one.

I suspect he was using 42ga so there was less of a change of it breaking.I wind pickups with a lathe that has a VFD so I can control the speed, and an optical switch hooked up to a counter. Tension is controlled by how much wax I put on my fingers as I manually feed the wire.I’ve been thinking of doing something more automated like this, now I have some inspiration to get started.I don’t want to diminish what this guy did. It’s a good start, but could be improved. Mainly by adding control over the winding pattern (linear or scattered), tension control, and better speed.",

Rant…You can take a bunch of leaded components, resistors, caps, transistors, even DIP IC’s and DIRECTLY wire-wrap the parts together quickly to make a circuit “blob” WITHOUT a soldering iron anywhere in-sight!This is space-wired stuff, no perforated proto-board (strip-board, Vero-board) needed. Changing/adding/removing components only means wrapping/un-wrapping. NO soldering.If you need to hold the leaded components (yes you can solder leads on SMT parts too) on a substrate but don’t have a perforated board handy, just push them through a piece of cardboard and then wrap the circuit directly on the leads. This has been done for ages – nothing new (I’m old enough to know).I would be dead in terms of FAST prototype without my wire-wrap/unwrap/strip tool (around $5 USD) with my thousand-foot spool of good wire-wrap wire bought long ago (surplus, Singapore, less than $20 USD).0.1″ perf-board is cheap, wire-wrap tools are cheap, wire-wrap wire is cheap (hunt), wire-wrap sockets/headers are cheap. Wire-wrap should be one of your first considerations when prototyping!At high frequencies a leaded-part wire-wrap “blob” will often out-perform anything on a PCB unless the PCB is very carefully designed. (Ground planes, layered ground planes, Parasitics!) When you wire-wrap a board just keep the wires at 90-degree angles, cross-talk solved. Use a strip-board with a single grounding point land. Don’t think wire-wrap is only for low-frequency low-speed prototyping.Rgds, Drone",

[Bhautik Joshi’s]
fisheye lens hack
works well and looks OK too. It uses a door peephole from the hardware store as the fisheye and a slide projector lens to enlarge the image for proper sizing on the camera’s sensor. He included an EOS lens adapter so that it is easy to install and remove, then grabbed a soda can and some foam for the rest of the build. This will take those fun bendy pictures but don’t forget that you can
correct for that in software
if you wish.

There’s nothing groundbreaking about this hack, called
the TweetWall
, but the craftsmanship is gorgeous! [Yergacheffe] had access to the right tools; an epilog laser and a thermoplastic bender (an item we didn’t know we needed until now… thanks a lot). It has the usual bits you’d expect in a Twitter ticker, an
LED matrix
and an Arduino. There is also an OLED screen that displays the avatar of the current Twitter feed. Because data is transferred over a serial connection the SD slot on that screen is used to cache images which helps to keeps the messages coming without delay. The end product is quite good, we’d expect to see it hanging on the wall of the pub down the street.

[Patrice]
hacked all of his classic controllers
for use when playing games on an emulator. He made the base station starting with a USB gaming controller. From there he soldered wires connecting the PCB pads for all of the buttons to the pins of a d-sub connector. The same is done on the classic controller, allowing him to switch them out at will. If you do the wiring correctly you only need to configure your emulator buttons once. This is a lot easier than trying to
find and use classic controller connectors
but you do have to alter that vintage hardware.

Hijacking The Mazda LCD Display

[Pieter] is in the process of adding a turbo package to his ride. He needed a status display for the boost but didn’t have a good way to mount an additional display. He came up with the idea of using the LCD screen that’s already in the dashboard, but the specs for it were not available. Wielding his hard-earned hacking skills [Pieter] used a logic analyzer to sniff out the communications to the screen.
He built a controller board
that overrides the data coming in from the head unit. The board is also able to query the car’s computer for data and display it in any format you want. What he ends up with is a stock look that he can customize for his needs. Nice!

They avoid getting under the dash at all costs, and with satellite radio add-ons and such, it’s pretty common to have people come in to the dealership with aftermarket electronics added under the dash. Unless they had to service/replace the LCD module itself, they would never know.You have to realize, todays mechanics are a different breed, most are trained to replace individual modules when they fail, and few understand how those modules actually work, and how they all talk to each other. The only ones that *do* understand are the few-and-far-between rockstar driveability techs, and geeks like me that have diverse and out of control hobbies.Not to mention the fact that [Pieter] is installing a turbo in his Mazda.

I started playing around with a MAC mentor, which is the same as the original Genisys, and I later got a newer tool on eBay that has the faster processor in it (has shiny buttons instead of dull). They have since released at least 2 newer models, but I think they are all pretty much the same.My reverse engineering goes as far as manually flashing the tool for newer OS’es, and cracking the software to authorize all of the applications. I am kind of hesitant to say anything about how I cracked the apps since that would definitely be covered by software piracy laws…It wasn’t that hard. The machine has a linux console that is accessible through the RJ45 port on top, using your average terminal emulation software. I believe the settings are 9600-n-8-1 for the serial port, I’d have to double check, it’s been a while.

Virtual Windows That Track A Viewer’s Position

Winscape
will let you replace that garbage-strewn ally view with just about anything you want. The two windows above are actually plasma screen televisions. In between them you can spot a Nintendo Wii Remote that is used to track an IR badge worn by the person in the room. As they move, the images on the screens are changes to simulate the change in perspective you would see out of a real-world window. Take a look at the video after the break. This is unfortunately not an open source project but the software is available for trial and we find the concept interesting. If you can write video processing algorithms you may be able to take the
Wii Remote Whiteboard
concept and turn it into a Winscape clone.

There are cars that increase the radio volume as you drive faster, and video games that ramp up the music as your gameplay improves (we’re looking at you SSX Tricky). Now you can add that feature to your workout with [Polymithic’s]
Motion Feedback MP3 Player
. It uses a
passive infrared sensor
to detect motion so there’s no need to wear any electronics. But if you used some Bluetooth headphones you could bring the system with you to the gym, just don’t exercise so hard that you blow your eardrums out.

Coin-op Pays Out When You Win

"hopper",
"mame",
"pic"
] |
The days of plugging coins into a stand up arcade game are sadly dwindling. [Dirk] figured out a way to prolong the nostalgia by incorporating currency back into the experience in a useful way. He
rebuilt the video game Raiden
to pay out a prize when you win the game. Now it takes a coin for each play but if you make it to the end you can recoup the expense.
[Dirk] took an original cabinet game, did
some dangerous work
to replace the old CRT monitor, and retrofit a MAME machine to handle the gaming. He’s using Windows and had some problems because of it but, as you can see after the break, things worked out in the end. The hopper hardware that spits out coins went through several steps from
the initial design
to the finished product, but it has always been based around a PIC controller connected to the MAME box via parallel port. This is a fun addition to
any MAME cabinet
.

While building some nixie clocks,[Blue_Metal] ended up destroying a few tubes. He found that having a tester sitting around would have been most helpful. Taking some pride in his tools, he put some major effort into building his
nixie tube tester
. It is quite visually pleasing, featuring hand cut brass framing, custom etched information panels. Scroll through his flickr set to see the build process in detail.

When [Justin Quinnell] sent in his
beer can pinhole camera
, we were just floored. The parts are easy to obtain, and the process for building and ‘shooting’ with the camera are near effortless.
The
really
impressive part of this hack is letting your camera sit for 6 months facing the sun. Yes, you read that correct, a
6 month exposure
. Check out after the break for one of his astonishing shots, and trust us, its well worth the click.

Obviously you’ve got too much hacking to do right now, but that game of Tetris isn’t going to play itself. [Branislav Kisacanin] has you covered with his
Tetris-playing robot
which is build with LEGO Mindstorm pieces. The setup is actually pretty complicated. A Texas Instruments DM6437 video development board watches the computer screen via a webcam and calculates the next move. It then outputs that to a grid of LEDs which the Mindstorm watches using a light sensor. See it in action after the break and then take some time to check out our
other
various
Tetris
based
hacks

Remote motion control
This project walks though a method of
controlling motors with an accelerometer
when the two are physically separated. Two Arduinos are used, with the user interface and the motor control connected via Ethernet. This must be useful for something; maybe it should be the next step once you
get your accelerometer up and running
.
CNC machine build
[Lucassiglo21] is doing a great job documenting his
CNC build
. The project has been ongoing for several months. He’s seeing some success with
milling simple PCBs
along with other millwork projects.
Condom starts a fire
Ever needed to start a fire and had nothing on you but a condom? Yeah, we haven’t either but that doesn’t diminish the fun of this whimsical ‘
Condom Hack Pack
‘ video. See the uses you never thought of for those rubbery package protectors.
Solderless PCB
Print your component locations on a piece of card stock and
populate the board without any soldering
? This is quick and convenient for a circuit that doesn’t need to last very long. It uses
wire wrapping
to connect the components, completing the circuit. [Thanks Frogz]

The DJHI 2.8 is now
available for preorder
. The
DHJI
acts as an alternative serial connection in order to protect
the Didj
from the 12V signals it would be exposed to with a direct serial connection to your PC. It also adds in a microSD card slot and makes the connection process as simple as plugging it into the cartridge slot.
[The Moogle], who was the winner of
our second Barcode Challenge
, also tipped us off about his
hack that upgrades the Didj to 64 Mb of RAM
.

[Alex Rosiu] picked up this instrument cluster from a 1992 BMW. After some trial and error he’s
hooked it up for use with a racing simulator
. You can see how amazingly well it works in the video after the break. An Arduino Mega takes incoming data from the PC and actuates the appropriate indicators on the module. [Alex] didn’t stop there. He got his hands on a full dashboard and is working on fitting
a joystick in as an H shifter
. Keep an eye on this one, we think it may one day become
a full-blown motion simulator
.

Beginner Concepts: Using An Accelerometer

"adxl320",

"pic"
] |
Accelerometers make for nice user interaction, that’s why every Apple product seems to have one included and the Nintendo Wii is still alive despite its underpowered graphics capabilities. Adding one to your project is pretty simple, just a matter of reading in analog data and interpreting it according to the datasheet. If you’re just starting out, here’s a tutorial on
how to interface an accelerometer with a PIC
microcontroller. They’re using an ADXL320 which
can be acquired
on a breakout board for about $30. The schematic and code are simple so even if you don’t intend to build the circuit (or want to use a different uC), this is easy to understand as an academic exercise.

Depending on how fast I sampled, along with how big the array was, I got it down to some decent stability, but it was always at the cost of speed, or accuracy, in regards to sample rate, making it skip across the screen. I don’t know if the 3 axis accelerometers all will spit out some wildly varying out put, or what, it just seemed like every few samples, it would say go from around .70 to .75 volts, to like .85 or something then back down, even tho it wasn’t moved. I got it smooth enough for my investigation and play with it, but as far as a controller, like I saw someone had made one to control a video game, it just seemed a bit unpredictable. Maybe a higher quality accelerometer would be better? I didn’t exactly buy something high end or anything I think, or maybe some filters on it before going to the microcontroller.

For example in Mario Cart were it is used to steer, it doesn’t matter whether it has some jitter because the carts always slip a lot and are very inert.When it comes to aiming they always use the Infrared camera of the Wii-controller.The accelerometer has a lot of jitter because it measures the derivative of the velocity which is in turn the derivative of the position.You can test your sensor by placing it on a rigid surface and not touching it in a way. Then it should give you very stable readings. If it does so, the sensor is perfectly fine. This means the jitter it outputs comes directly from the applied acceleration which is by itself jittery.I had the exact same problems with my balancing robot. Either the data is too jittery or it has too much of a lag. The only solution that worked for me was to use a Kalman Filter with the data of a rate-gyro and the accelerometer. This gave very accurate and smooth angular data.",

(because integrate(integrate(offset, t), t) = 1 / 2 * offset * t^2; assuming offset is constant for the integration period)The other problem is that you have to subtract the constant acceleration vector caused by gravitation before integrating. (and the orientation of this vector is normally not known either, unless you know the exact angle of the sensor)Regarding the thing with the ADC reference:The current setup uses the power supply as the ADC reference. Since the output of the accelerometer is ratiometric to supply voltage this technique gives you acceleration values independent of voltage.",

Improving A Motorized Toy

"steering"

[Dan Fruzzetti’s] daughter was delighted to get a motorized vehicle from her Grandparents, but [Dan] was unimpressed with the stock features. The lead-acid battery supplied remarkable life between charges, but the vehicle only had one feature: a go button that routed juice to the bipolar motor. After the break we’ll look at his improvements to the drive train, steering, and cosmetics.
After cracking open the top hatch he wired in a double-pole double-throw switch that reverses the polarity of the motor. This way the switch to the left of the steering wheel can be toggled to shift from forward to reverse. The little red button above that switch controls the horn he added into the mix. Although not pictured here, he did some work on the steering column to increase the rotational limit of the steering wheel, which improved the ability to turn and steer.
The finishing touches were more cosmetic. The photo above shows the addition of two red LEDs for tail lights and at the top you can see the LEDs added to the decals of headlights. [Dan’s] improvements cost pennies but they make this
Power Wheels
knock-off so much more fun for his daughter.

Four Channel Logic Analyzer
|
Mike Szczys

[
"Tool Hacks"

[
"logic analyzer",
"pic18f4580"
] |
If you’ve got a graphic LCD lying around you can build this
four-channel logic analyzer
with a couple handfuls of cheap components. [Ronald de Bruijn’s] design uses a PIC18F4580 to sample up to four logic inputs at a maximum resolution of 2 MHz. He’s included the PCB artwork so that you can etch your own board. Having a logic analyzer around can really make your life easier, allowing you to
reverse engineer communication protocols
and troubleshoot your own design problems.
[Thanks Juan]

Zune Gets Hacked, OpenZDK

Here is one that really got some of us at the HAD offices excited (yes, we own Zunes). The introduction of the
Open Zune Development Kit
(
Internet Archive
). Sure, there was
XNA
, and we even toyed around with it. But anyone will quickly realize just how limited XNA is, especially with older hardware.
OpenZDK is in its infancy, with only
one application
thus far (don’t worry, you can still use XNA apps too). But we wanted to give it a shout out and let the hacker community make this potential into a reality.

This video brought a smile to our faces. [Griffin Milsap] is
creating live music using an orchestra of solenoid
instruments. Each solenoid is set up to strike an object such as a bowl or mug. The trigger mechanism is a light sensor inside of a ping-pong ball. The collection of instruments is conducted by a motor-mounted green laser. When the beam of light passes by one of the ping-pong balls the photo transistor inside actuates the solenoid and a note is played. The pitches are quite a bit more random than the
Robo-vibe
, but it’s delightful to hear the results that [Griffin] has achieved.

Clock Hides Time Until You’re In Close Proximity

[Alan] is branching out beyond the Arduino with
this clock
. He’s still using the same code but built this board around an ATmega328 and the components he needed, saving his Arduino board for further development. The concept uses a character display housed in an old iPod Touch case. The build relies on an infrared sensor to actuate the LCD backlight. The closer your hand is the brighter the light.
The Maxim DS3232 RTC chip keeps time in this application. We’ve
seen this little marvel used before
, popular because it uses temperature compensation to maintain accuracy. If you’re interested in this part, check out the library file that [Alan] wrote for it.

Stickybot has gone through a
pretty radical upgrade
. You may recall the
gecko looking glass walking bot
from all over the net. While it was pretty cool, the technology has gone much further. Not only is it designed to look like a gecko, the feet are actually made to adhere to surfaces in the same manner. They are using an adhesive system based off
Van Der Waals forces
. Though the stickybot 3 doesn’t walk yet, the feet are already impressive. Look how little of the foot is actually making contact with the glass. See how easily he can remove and re-adhere it? Simply amazing.

If you are anything like us, you are suddenly filled with childlike glee when you think of big fluffy poofs of cotton candy. The thought of making it at home has a certain appeal, but that machine is a mystery reserved only for those elite enough to get through cotton candy maker school. Or so we thought. As it turns out, it is
actually quite simple
. You can make one and be serving cotton candy in an afternoon with parts you probably have sitting around. The video above is pretty easy to follow, but if you want more information, there’s
an instructable
as well.

Several people have been asking a similar question to,
“How do you at Hackaday keep track of and organize all your equipment?”
-[Jeff Allen] and others.
We have a variety of resources to help you keep track of your tools, equipment, parts, and supplies! Follow us after the jump for some tips for keeping your workspace clean and tidy.
First and foremost, we admit, we’re not the cleanest of bunches. We work on several projects at a time, receive ungodly amounts of mail and paperwork, struggle with dust and other allergens, all while writing wonderful articles. So please forgive us if our workspace is just a little messy.
So what can I use to help keep my parts orderly?
[Andrew Lybarger] asked us if
Spice Containers
would work, and was worried if the magnets would interfere with electronics. In short, we think they would work perfectly. Resistors, LEDs, etc should all be fine. We wouldn’t put our expensive ICs in there though, just to be safe.
For those that don’t want magnets, we suggest
clear dividable containers
. Or, my personally favorite for on-the-go hackers.
A tackle box
, its many holding areas for hooks and other things work great for transistors and caps. The bottom part of the boxes is usually quite roomy to fit a soldering iron (or two).
HAD writer [Devlin] prefers to keep all purchased components in the rail/tube/bag they come in, stick a label on and they’re good to go. Writer [Mike] goes a step further by keeping the purchase order and a spreadsheet on his PC with a list of parts and supplies, all it takes is a GREP search to find the right IC.
I just have too many tools, help me HAD!
If you have one or two items that can fit in the above mentioned tackle box, you’re set. But some here might have everything from a sledge-hammer to a pair of tweezers. There is no real easy way to say this, but buy a tool chest, or better yet
make one
.
How do I keep my workspace clean?
First and foremost, prevention. When you’re done with a project, put your tools away! We would like to slide in a little note here to mention not only a clean work environment, but a
safe one
.
For a computer workspace, nothing is worse than horrible amounts of cables creating a rat’s nest. Zip ties and a
little ingenuity
can go a long way.
What about the ungodly amount of paper work?
Whether digital or real, find a filing system. I know several HAD writers rely on
Google products
. And with Gmail, Calender, Documents, and more all interlinked, I’ve never lost an important file.
Outside of the digital side though,
accordion files
are great! We have several around the office for articles, finances, and more. For a lot of mail,
slot divided organizers
work wonders (And we always know where a pen is!)
Final note:
Don’t let your desk and work area get overfilled with tools and supplies in the first place. If you clean up after you’re done every time, you’ll know where everything is and will spend less time looking and more time hacking.
Here is where the fun begins.
We get to now ask the fun questions; how do you, our readers, keep organized with your equipment, tools, parts, supplies and other necessities of hacker-dom?
Want to ask us a question instead?
Send your questions to askHAD@hackaday.com for consideration. They will be chosen based on a complicated system of random number variation involving furry woodland creatures and how we feel at the moment that we read them. Do not get offended if you question does not get published. We get tons of questions already and we don’t intend to publish them all.

I picked up 500 at All Electronics a long time ago, wish I could find more as I’m running low!For larger/bulk parts that don’t fit well in the Planos or would take too much room, and aren’t likely to be damaged by bent pins, I use a system of nested ziploc bags. For example, I have a gallon bag labelled “Capacitors”, which contains quart bags each containing a type of large electrolytic; and one bag for “Assorted”. All of these bags are stored in Rubbermaid containers. I make a tiny cut in the side of every bag, this lets out excess air under the weight of other bags; since I don’t want to waste space storing air!BTW, I’ve never had problems with the Plano latches. But my newest ones have crappy hinges – the lid tends to fall off when in the open position. I’d rather have the faulty latches, as I’d imagine they could easily be replaced with velcro straps.",

"content": "Well, my hacking workbench turns 35 this year and has been re-organized at least half a dozen times.The best thing I’ve found for organizing individual parts is cabinets with the plastic drawers. 4 or 5 years ago I went out and mough 5 or 6 of them in the same coulour, size, style, etc. There is one for resistors, one for caps, several for ICs (more on that later), one for various assembled bits (LCD displays and the like), one for small cables, one just for connectors and adaptors.The plastic drawers can be death for ICs, especially CMOS, MOS, and ECL (yes, I have both of the latter in stock). Each drawer is thus lined with black anti-static foam I bought on Ebay. It was $10 for 4 2’x3′ sheets. More than I’ll ever need. Drawers containing PICs and other sampled parts (you _do_ get all your Microchip parts through the sample program, right?) are put directly in the drawer, tube and all.Surface mount resistors, caps, and inductors are stored in containers bought just for that purpose on ebay. $50 for enough room to store 50,000 components in ~200 values.Larger things are kept in one of 3 sizes of stacking tupperware style bins. (Chinese food containers are good for the smallest size if you are cheap). The largest are ~8x10x18″ and reside on shelves in the basement. Those are sorted into broad general categories.Teh most valuable part of all of this…The label maker that is used to put a label on _every_ drawer, even if the component are being stored temporarily.There are also some larger drawers that I user to hold components collected for a given project that will be gotten to someday. When I run out of those drawers, I know it’s time to sit down at the bench and actually build/finish projects.Tools live in an artists/draftsman’s carousel and a small box that lives on the bench for a few pens, probes, and Xacto style knives. (Another great place for small part manipulation tools is the local surgeon…)This leads to the whole conversation of bench design itself. Mine has shelves which hold instruments like bench dmm, power supplies, the soldering station, a few older parts bins that I can’t bear to part with, etc. The room design prohibits putting large instruments on the shelf (sloped ceiling) but that is the perfect spot for the O’scope, spectrum analyser, freq/function gen, etc. Along the front edge of the shelf is a piece of 1.5″x1.5″ angled aluminium with connectors in it that route to power supplies under the bench, audio in/out at the computer across the room, ethernet, a usb hub that goes to the computer, and the like that always seem to clutter up the workbench.Bench surface is also something to think about. Wood is good but gets gouged/marked/burned, etc. laminate is decent but gets scratched, Drafting board surface is great but is easily melted. A nice hunk of plate steel might be nice. Mine is all of the above in different places with holes in the wood section just the right size to hold various connectors that are soldered often. (1/8″ jack, 1/4″ jack, RCA, N, SMA, etc).And don’t forget to illuminate it all well. Magnifier lights are cheap @ Harbor Freight.",

But, I’m not the ‘sledgehammer to tweezers’ type so tool control isn’t a huge problem for me.I have to laugh though – I have this organization scheme in place, but my work desk is utterly destroyed right now.

They have some of the better prices out there, but as with most industrial stuff, it’s still pricey sometimes.I’m a big fan of the cardboard storage bins, haven’t been able to justify spending $200+ on a fully loaded pick bin rack yet, but the cardboard bins and some shelves work well. I also picked up a number of compatibly or equally shaped cardboard boxes with the open-top flaps for larger items, which I label on one end and shelve.For smaller electronic parts, I mainly use the plastic drawer organizers (though I pine for the metal ones). For things like connectors that I may need to take off-site I use the plastic divider bins.I have yet to get those “watchmaker’s cases”/”spice bins”, but they’re on my list.Lee Valley toolshas them for WAY cheaper than the ones linked above (although non-magnetic). They also have polycarbonate “Shop Storage Tubes” for a good price.Pro-tip: your local Big Lots may have small 9-compartment and larger 20+ compartment bins for $1.50 and $2.50, respectively, which is an awesome deal. They also have the6-quart Sterilite 1642for between $0.90 and $1.50 depending on the season (really). I probably have over 50 of these by this point and they hold up well and are sized to work with the other larger bins to maximize space.Looking forward to following this thread, I’ve been spending more time organizing than working lately.",

If they are high enough, then you as the engineer, take action to shield your components from them.The actual effect that a field will have on a given semi conductor will depend on many variables, frequency, strength, orientation, etc. The only components (other than the obvious sensors designed to be effected) I can recall that are even tested or rated for these things are space grade semiconductors, where large E and B fields happen sometimes.",

Shortly after
finishing his
Makiwara punching bag
, [Abieneman]
wired
and
programmed
an Arduino to an accelerometer to find out just how much acceleration (and with some math, force) is behind his punches. The project is simple and would be quick to reproduce for your own measuring and experiments: all that he used included an Arduino,
accelerometer
(with A/D converter), LED displays (and shift register). We were a little disappointed to learn of how much static the accelerometer produced, so measuring things such as impulse, energy, and pretty much anything
not
kinematic is nullified. But it makes us wonder, how much static would be in say, a
Wii Remote
punching bag?

You can almost always reduce the noise of a sensor reading by instead measuring its integral and then deriving in software. I’d actually suggest taking a second step in that direction. Make a reflectometer out of an IR LED and a photosensor (preferably one that’s only sensitive to IR and not ambient light), and mount it on the back. That should get you a really clean, really fast measurement of how much the board is bent- as the board bends closer to the wall, the reflected light will appear brighter to the sensor. First derivative of that tells you the board’s velocity, and the second derivative tells you the board’s acceleration.",

"content": "I think that your physics are incorrect. This isn’t a simple F = ma system because of the board, but the good news is you don’t need to worry about arm weight.It is easier if you view it from the point of view of the board ‘system’. You want to solve for the force being applied to the board. You are measuring the acceleration at one point near the tip of the board. The accelerometer needs to be rigidly fixed to the board, this is critical.The board is acting like a spring itself where the deflection produces a force. You can experimentally find this force (use a force scale, correlate deflection with force, just like a simple spring).Now using beam deflection dynamics you could solve for the force being applied to the board based on it’s acceleration profile. This may be difficult. It is going to be something like F_punch = Mass * accel + F_spring_board.Now the trick is finding what mass to use. This is hard because you are essentially rotating the board, not moving it in a straight line. So instead you’ll need to use rotational inertia, and we are getting too complicated.In the end, solving for the actual force might not be all that important, and just having a relative metric probably is. If that is the case, just rigidly mount the accelerometer and measure the max ‘g force’. This is proportional to force in some know way and that is all that matters. It gives you a way to compare yourself to others and track your progress.Another trick is to apply known forces and then measure the acceleration of the board. You can then use these tests to back out your applied force while punching.",

[Dennis] is using
a robotic arm as a chess opponent
. Rather than using
an under-board movement system
, a
Lynxmotion AL5A
robotic arm plucks each piece and moves it to the next space. He tells us that he’s using a Python script that he created to process the moves and decide what’s next. That must mean he’s using a webcam to capture the location of the pieces on the board. About half way through you can see the robot run into one of the pawns. We’d like to know if he has problems with picking up the pieces as the game progresses and they get further away from the center of each square. From what we can see, looks like a great job!

Finally, a good use for those EEG headsets. [Andrew] has set up
a system that will turn his TV on and off if he focuses hard enough
. He’s got the software set to trigger an IR LED when the “strength” gets high enough. When the action starts, around 4:30 in the video, you can see that when he raises his arm the meter on the screen begins to raise and the TV turns on. Though not immediately useful, we can’t help but get a little excited seeing him literally turn his TV on with a thought.

Convert An Early 60s Polaroid To Modern Film

[Adam] sent in this cool project. He has
modified a Polaroid J66 camera to use modern film
. Most of the initial modifications look fairly simple, but things get a little more complicated when they also convert it to a fully manual camera. There is a section that explains a neat little trick of using a cheap solar panel attached to your computer sound card to figure out what ISO the camera is shooting at.

Today we received the question,
“How to control a web cam via internet,
i want to use it for security reasons, always out of the house and my PC connected want to open the cam from time to time to checkout if something wrong!!”
– [Mohamed Saleh]
What a fun project we thought! And so many different ways of tackling it. Find out what we suggested to [Mohamed] after the break.
Initially we wanted to create an extremely complicated setup, using a USB camera, server, webhosting, and a ton of scripts/programming to create a
rather sweet camera setup
.
But of course, complication breads problems, and while digging through our box of parts and supplies we stumbled upon an old
Axis 206 IP Network Camera
. What could be easier than all of the above built into one slick device!
The camera comes with an Ethernet cable, wall-wort for power, and a CD with instructions – we just threw the latter away and winged it, by finding out how to reset the device, then its default ip, we had view of the camera within our network in no time.
A simple port forward of 80 and we could view it outside of our network (so long as we typed in our IP). What we would recommend however, is setting up a DNS (
DynDNS
is great) service on a computer within the network that points to the cameras IP. That way the URL becomes
http://www.HADCamera.com
, a lot easier than 249.135.184.204:80. (Both are fake URLs sorry).
Taking it further, if you had a computer nearby you could setup a simple stepper motor and
control the position of the camera
.
This is of course our take on the matter and part of Ask HackADay is what our readers would do, so how would you setup a home security camera?

It started out good, until this part:“But of course, complication breads problems, and while digging through our box of parts and supplies we stumbled upon an old Axis 206 IP Network Camera. What could be easier than all of the above built into one slick device!”Seriously? If this had been a comment left on a HaD post about putting together your own networked camera, it would be considered trolling. This is absolutely counter to everything HaD is about. If every project followed this line of logic, we wouldn’t have any content on this site.You might as well rename this to “Ask Google”, since that would have given you the same answer.",

One aspect of it that we are really incorporating (and thus far is a rousing success) is not only HAD answering the question, but our readers input as well.I would like to point out if we feel the asker might just want something quick and easy (such as in this case) we answer as such. If the question was “I would like to find a way to interface my usb camera over the internet and include the functionality to take over the world while you’re at it”, we might have gone more indepth with the specifics that he/she asked for.In closing, keep it awesome,Jakob Griffith",

Packshotnik
is a circuit designed to help with creating 360 degree images. It consists of a main board and motorized rotating platform. The board can send IR signals to a camera to snap pictures at intervals in the rotation. The source code, schematic, and pcb files are all available from the project page. While he is using this primarily for rotating 360 degree images, you could also just plop your camera onto the platform and end up with panoramic sets.

SNES Controller + USB + Accelerometer

As we posted about [Atarity]’s
XBMC hiding in an SNES controller
, we were finishing work on a
tutorial
for [Adafruit]. The tutorial combines a
Teensy
USB development board with a 3D accelerometer inside of an SNES controller. The Teensy is programmed to poll the SNES controller buttons and read the accelerometer values. The buttons are set to keystrokes and mouse buttons, and the accelerometer values are processed into mouse movement. Programmed to play
Portal
, we created a video showing how to use the device. You can see it after the break.
It was not quite as easy or quick as the typical PC gamer left hand: WASD, right hand: mouse stance. However, we can think of a number of other games that could be improved with the use of a device that, with a bit of hacking, could time keystrokes as the user needed. With a bit more hacking, the device could be made to brute-force passwords. What else would you do with this?

Thinking of buying a new bandsaw? Stop it.
Make one instead
. Not only could you save some money, you could customize it to be exactly what you need. There is a step by step breakdown of the entire construction with tons of great pictures. He even has some great info for
general bandsaw use
if you’ve already got one.

I’d be too afraid to use it just knowing that a bandsaw is easily one of the most dangerous tools in the shop.I wonder if he’s done some controlled tests by breaking the band on purpose to see how well the wood parts handle it. I do like that he thought through the sawdust collection it could be fairly dangerous with his nearly all wood design if dust accumulates in the moving parts because it takes a lot of heat to cause metal parts to burn but the heat caused by friction + sawdust + wood parts could quickly become an inferno. I’d suggest keeping an extinguisher and have a kill switch somewhere away from the machine body itself (you don’t want to be reaching into flames to hit the switch) – maybe put it on the cord somewhere near the plug.So, if anyone thinks to build one, carefully consider these things and keep the machine clean! Saving money is a great thing, and hacking is nirvana, but losing limbs or burning down your home because you didn’t think through the safety aspects of your design will certainly put a damper on your excitement later.",

Then, keep a maintenance schedule and replace certain parts well before they would fail under torture tests. The bandsaw tires would be another good candidate for tests like those.",

Check out this slick
strobe array for dance parties
. Controlled by a DMX512 interface, only a small modification was necessary to get the strobes working. If you’ve played with a small commercial strobe light, you’ll know there’s a potentiometer to control the strobe speed. He simply soldered a relay after the pot. This allows him to tune them to be charged and ready for when the relay is closed.

What Kind Of LED Matrix Does Your Vodka Come With?

Medea Vodka comes with
a bottle that includes a blue scrolling LED Marquee
. OK, great? It’s an interesting marketing ploy but kind of a waste don’t you think? Friends, it’s up to us to repurpose this hardware. It can’t be that difficult to hack into the programmable display and make it do your bidding. Our friend Google tells us that you can get your hands on this 750 milliliter bottle for about $40. That’s around $25 more than a passable grade of Vodka sells for, a mere pittance for the challenge of cracking open the hardware for fun
and profit
. Don’t forget to document your work and
tip us off
once you’ve accomplished something. See Medea’s programming instructional video after the break. Oh yeah, remember to hack first and drink later… cheap soldering irons get hot!

If you’re interested in learning about Very Low Frequency communications
take a look at what Larry has to offer
on his site. He’s put together
a guide to VLF receivers
that is short enough to read and clear enough to understand with rudimentary knowledge of circuits. He builds
a simple receiver
as a working example and
a high-powered transmitter
that can put out over 2600 watts. Let’s face it, radio operators were the original electronic hackers. Get back to our roots and learn the ways of the transistor.

The
Winduino II
uses fins to pick up the movement of the wind and translate it into music. Each fin is attached to the main body using a
piezo vibration sensor
. The signals are processed by an Arduino housed inside and the resulting data makes its way to a computer via a Bluetooth connection to facilitate the use of
Max/MSP
for the audio processing. Included in the design is an array of solar panels used to keep the battery for the device charged up. Hear and see this creative piece after the break.

[Alan] noticed that his external hard drive was getting quite hot to the touch after a few hours. He says that it was probably designed to handle the heat sufficiently, he thought it would be fun to
beef it up
. He’s using a pic 12f675 microcontroller as the brain and an LM35 temperature sensor. The Fan speed is varried in 8 steps from 35 degrees C to 45 degrees C.

[Ytai Ben-Tsvi] wanted a rapid prototyping tool that could be easily and cheaply built at home. He came up with
the PICMAN
, a breadboard compatible PIC based board that has everything you need to get the ball rolling. He’s using a PIC18LF4553 which has built-in USB support that can be used with a bootloader for programming. The board also features a voltage regulator for non-USB power sources, some indicator LEDs, a user-defined button, and a reset button. The chip is on the underside and a combination of through-hole and surface-mount parts make for a one-sided PCB that can easily be
etched using the toner transfer method
. You will need a PIC programmer to burn the bootloader firmware the first time but once that’s done this becomes a self-contained package.

Laser Cut And Printable Cases

If you’re like us you’ve got quite a few prototyping tools that are bare PCB boards. If you’re using them a lot you might want to protect them with some type of case but the lack of mounting holes can make this difficult. One popular solution to this problem is to design a case for a perfect fit, then cut it with a laser or print it out of plastic. We’ve got examples of both.
[Stewart Allen] set to work designing
laser cut cases for the AVR Dragon and the Bus Pirate V2go
after seeing our post about
on-the-go prototyping
. We think this is especially important if you have an AVR Dragon as it’s been
known to bite the dust
if the bottom is shorted out. If you have access to a laser cutter you can download is DXF files and the models and cut your own.
If you don’t have a laser cutter but can get some time with a 3D printer check out the
Bus Pirate V2go printed case
and the
Arduino printed case
.

Mechanical Scanning Television

"mechanical",
"television",
"tv"
] |
This project explores the early days of television. Above you see a view from the back side of
a mechanically scanning television
. The black disk spins and the holes, aligned in a spiral pattern, create vertical scan lines for projected light to shine through. In this case, [Eckhard Etzold] is using red, green, and blue LEDs to create a color picture. As you can seen in the video after the break it does a pretty good job. The main problem being that the scanning disc on a
mechanical TV
has to be much larger than the actual image. How big would the disk need to be and how fast would it spin to produce a forty inch image? We still think this is a better method than
transmitting video data in parallel
.

HDD platter would give image like 10mm across and the holes would have to be very precise and small. Maybe a vinyl LP disc spun at 7200rpm? I don’t know, sounds totally safe :D",

Reader [Eric] sent us a powerfully informative, yet super simple
hack for the MindFlex toy
. Don’t worry, it’s not another worthless
shock ‘game’
, And it’s using an actual interface instead of the
built-in LEDs
.
With two wires for the serial protocol, and an Arduino, you’ll be able to view “signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma” brainwaves. While it’s not medical grade, it’s a lot more intuitive than previous interfaces.
The original intent was for a system called
MentalBlock
, but we’re wondering what would
you
do with brainwave data?

It is quite obvious from the raw data that there are brainwaves in there. There’s also a lot of noise, but NeuroSky’s big claim is that their fancy software can filter that out.One can debate whether one noisy EEG channel is worth anything, but it seems very obvious that they really are amplifying the low-level signals that contain EEG data, they really are doing FFT on it, and they really are using that as the basis for their other data products. They are not doing GSR and by any reasonable definition what they have produced really does produce output based on brainwaves.So stop lying about this. The device may not be as useful as neurosky thinks, but it definitely is doing what they say it does.",

Trans-dermal EEG works better, but a non-medical device will probably not require putting needles into the scalp.The toy itself, not the MindFlex headband but the floating ball part, is meant to be simplistic and not really controlled by individual bands of brainwaves. If the headband has that extra data available, why not use it.",

Yet.For reading minds or recording dreams, it will not be something crystal clear, it won’t even tell you if you dreamt of a person. But it might tell you what mind set you were in during a dream. REM should show up if you had the raw data, different bands will show up and let you see certain responses of panic, happiness, etc. It’s a small bit of vague information, but more information than is available without similar toys and tools.",

Using something like this to keep track of where you are *AND* setting up your goal so you can see how close you are by visual feedback. Next step, adjust the binaural beats audio you’re listening to in real time response to what your brain is doing. Can’t get out of beta brainwave range? Lower the binaural beat audio file being generated going to your headphones.Heck, I’d never come up for air! YMMV",

Flux Paste Applicator Gun

[Luciano] didn’t want to drop a lot of cash into a flux and solder paste applicator so
he built his own for about $5
. He re-purposed a hot glue gun which you can usually find at a dollar store. After removing the heating element he inserted the body of a syringe. The plunger has been modified to use a knitting needle inside of some plastic tubing. After taking the picture above he made an improvement by adding a milliliter scale to the plunger, allowing you to meter out the paste and also gauge how much remains.
