Though it is in the beginning stages of development, the
Distributed Flight Array
is already looking very interesting. Each unit can scuttle across the ground using the down force from its prop, but when 4 or more join forces, they can take off and fly. The documentation shows that they should be smart enough to fly in random configurations, though in the video we only see the standard 4 prop layout. This is being worked on by the same people who produced the
balancing cube
.

DUO 128 Elite, 4 Bit CPU

We’re not sure how we missed [Jack Eisenmann’s]
4 bit TTL CPU
when we were tipped off the first time, but we’re glad it was sent in again for us to feature it.
41 different ICs (mostly TTL) come together to comprise the DUO 128 Elite. While
the architecture
is a little different than what we’ve seen before, using “nyckles”, the DUO 128 Elite still works perfectly. Catch a video of some example programs, including pong, after the divide.

An Arduino Watch You Would Actually Want To Wear

Leather work, copper tubing, small easy to use package. Now
that
is a beautiful
Arduino Watch.
[Matthew Garten] has retrofitted his old Arduino Watch and given us
the details
that we crave.
Previously
, all we had was a video and a few pictures of a quite uninviting watch. But now we know it has temperature, range finding, and trackball input while displaying time, games, and more with its 128 by 128 pixel OLED 16 bit display. And did we mention the much more enticing
steampunk case
?

Getting Your Message Across At Commencement

[Yomagaocho] is graduation from Northwestern University on June 18th (wow that’s late in the year… they must be on quarters). He decided to
spice up his mortarboard
for the commencement ceremony. A normal message wasn’t good enough, and even
a solar-powered diorama
wasn’t going to suit him. Instead he added 256 addressable LEDs to the top so that he can get his message across without being limited to a couple of words. See it demonstrated after the break.
He was nice enough to give us
the technical details
. The matrix is a 16×16 grid mounted in some laser-cut black acrylic. We immediately wondered about the display working in sunlight (a June graduation will probably be outside). He didn’t use any current limiting resistors with the LEDs, dangerous to the longevity but this should provide maximum brightness. It’s certainly a geeky concept, but having the ribbon cable that controls it trailing down into your robe might make those graduation photos a bit embarrassing a few years down the road.

Did That Table Just Move?

A
table and chair that can move
around by themselves? What’s next,
suicide booths
,
self-replicating robots
, and Star Trek styled
tablet computers
? It seems that [Adam Lassy] is moving in that direction. He took this furniture from Ikea and made some neat modifications to give it mobility. Each of the four legs has wheels on them and the legs themselves rotate in unison to change the direction of travel. We could see the table as a more practical drink delivery system than
the Bar2d2
. It certainly would make for some great late-night pranks but the chair motors need to be silenced before that can happen.

Did you order that 4-port USB hub because it was almost free but now it’s just sitting in your junk box? Why not
turn it into an In System Programmer for AVR chips
? [Paul] came up with HUB ISP as an answer to the chicken-or-egg problem we’ve seen with
other diy programmers
. It uses the data wires from four different USB cables to program AVR chips, enlisting the help of a 74HC00 NAND gate along the way. You do not need to have a programmed microcontroller as all the magic happens on the software end of things. The one caveat is that [Paul’s] method currently only works on Linux machines.

Building an ISP programmer isn’t that hard either, it’s very straight forward and there have been plenty of guides for the beginners. It felt like the guy was saying “ISP programming is too complicated for you to understand, so go get an arduino or teensy.”As hackers we constantly strive to learn how things work, and to share that information freely with each other. The best way to learn is to do: Pick up a soldering iron, build a simple programmer and learn how to work with a microcontroller.

"content": "Hi, Paul here…. the guy who made this.@charliex, does your windows version actually work?The main problem on Windows or Mac is libusb’s lack of usb_detach_kernel_driver_np(). Everything else you did sounds reasonable, but #ifdef’ing out that bit probably kills any hope it would work.On Linux, that asks the kernel to unload its driver, and then you can claim the interface and send control transfers to it. Windows just doesn’t support this from userland, as far as I’m aware.There certainly is some way to do this on Windows… I just don’t know how. But the USB-IF compliance test program does something like this, where it takes over a hub and uses it to subject your USB device to all sorts of scenarios to check if it’s USB compliant. Older versions required you to have a PS2 keyboard and mouse, because it apparently switches the entire USB protocol stack for its own. I’ve run it several times, but never seen the source, but you can get the binary for free athttp://www.usb.org.The main problem, even if you’re able to send control transfer to the hub, is if Windows is still using it, the host controller driver will see new device arrivals and try to do lots of stuff. You have to keep the ports disabled to do this kind of I/O.I really never intended this to be Linux vs Windows thing… I simply use Linux and even when I had this crazy idea, I figured Linux wouldn’t let me detach its driver for the hub and let me have exclusive access, at least not so easily from user space, but it did!Also, it looks like everyone’s missed the ideas (near end of the page) about improving the timing and somehow using the root hub. If anyone could figure that stuff out, it might be possible to do AVR ISP programming using only 3 USB cables and 3 resistors… no hub and no NAND gates!",

I’m sick of trying to use an ‘old’ Atom 1.6ghz board with a serial port on it for this sort of stuff, and usb->serial adapters don’t always work properly, especially under 64bit Windows. This would certainly come in handy, as I already have a busted-open 4 port hub here, casing just shattered after falling from my table. I triple-boot all three major OSes, so I could care less if it’s Win32, Carbon/Cocoa/ObjC, or native Linux C code, and I’ll probably play with charliex’s modification to see if/how it works.",

HaD Store Update: New Stickers, Shirts, New Logo

The Hack a Day store is still going strong. We’re really enjoying the fact that when you buy a Hack a Day item, it was made by one of us. We hope we can keep this up. It makes our merchandise mean so much more, we think.
We’ve been getting tons of requests for other colors of stickers as well as other products. Other colors of stickers is easy enough, we now have black, white, both gloss and matte, light grey, and just starting today, glow in the dark. We’ll be updating the store as we run out, or buy new colors. We only have a little bit of the glow in the dark right now, so if you don’t want to have to wait for more to come in, you better place your order quick.
We have also received a steady flow of requests for T-shirts. Unfortunately, we just don’t have all of the equipment yet. So, we’ll begin taking pre-orders for t-shirts today. As soon as we have roughly 30 pre-orders, we should be able to start making the shirts. To begin with, we’ll be doing white logo on black shirts. There’s also a Custom shirt option that gets your name placed on the front of the shirt as well, though that does come at some additional cost. Maybe after he gets all the kinks worked out, [Jakob] will grace us with
shirts to sell
as well.
There is also a product that has been the source of a lot of discussion between the staff. A new logo, designed by [Caleb]. You can see it above. Some feel that we should adopt it as our new logo, since the old one is kind of a
generic biker symbol
. The new one reflects a little more what we do. [Phillip Torrone], the founder of Hack a Day and designer of the old one likes it and says ” love it … i say go for it – evolve or die :)”. What do you guys think? Even if it never becomes the site logo, it will be for sale in the store.
[update: Judging by the feedback, we’ll be sticking with our original logo. Custom designs will be available in the store though. Email me directly(caleb@hackaday.com) to discuss getting your design on there. ]

Even if you fixed the proportions and simplified the tools, angry/evil skull-and-crossthings are MUCH more generic than the identifiable logo you’re using now.Rule of thumb: if you can’t imagine people doodling a logo on their notebooks between classes, ditch it.

Culture Shock II, a robot by the Lawrence Tech team, first caught our eye due to its unique drive train. Upon further investigation we found a very well built robot with a ton of unique features.
The first thing we noticed about CultureShockII are the giant 36″ wheels. The wheel assemblies are actually unicycles modified to be driven by the geared motors on the bottom. The reason such large wheels were chosen was to keep the center of gravity well below the axle, providing a very self stabilizing robot. The robot also has two casters with a suspension system to act as dampers and stabilizers in the case of shocks and inclines. Pictured Below.
The next thing we noticed were the strange semi-circles mounted above the casters. Upon further inquiry we found that the robot uses 10 lasers to project cross-hairs on the ground so that it can use its stereo vision at night.
The robot has two stereo vision cameras from
Videre
, a brand that has been very popular at this year’s IGVC. The cameras overlap and provide the AI with a pixel-associated 3d point map. The team also came up with a clever way to adjust the camera to different lighting situations with two “candy canes” sticking out into the robot’s field of vision. The robot can look at these and use an algorithm to adjust the colors according. This helps greatly with white line detection. (The robots must stay within two white lines painted about 10 feet apart on the grass.)
Along with the stereo vision the robot also features an Omnistar-VBS enabled gps capable of sub meter accuracy and a
digital compass
. Aside from the driver software for the cameras, the robot is written completely in Java. The AI uses frame-by-frame mapping. Each frame the robot sets an objective out in the distance and moves towards it. In the next frame the robot checks to see if that objective is still reachable and moves towards it, otherwise it changes its path. To get around objects the robot hugs the obstacle until it is behind it. The system is a hybrid of mapping and reactive AI.
The robot’s brain is a 2.4GHz Intel Core 2 Quad running 32bit windows. It has a solid state drive and 4GB of ram. One cool thing to note is that all of the sensors and micro-controllers run off the ATX power supply for the computer. Instead of using an inverter they found a suitable 12V ATX supply.
The rear control panel is pretty neat too. It has a touch screen, switches for all the main components, and status LEDs. Below it you can see the very back of the computer, housed in a shuttle style thermaltake case.
If you take the panel on the front off you are greeted with a view of the robot’s power and signal distribution. The green board is a
Roboteq AX3500
which runs the motors and manages the PID feedback. The robot has 70lbs of sealed lead acid batteries in its base which allows it to run for approximately two hours. The remote E-stop (required by the rules) for this robot is actually a remote garage door opener hacked into turning the robot on and off.
We’ll finish with a shot of happy* engineers working away on their robots.
*depending on the state of their robot

Color Clock Makes Telling Time Impossible

[Bogdan] set out to build the all-too-familiar binary clock. But, he didn’t want to be ordinary, and set the goal of making the clock as hard to read as possible.
What he ended up with is a clock
that is almost impossible to read correctly.
He’s using colors to tell the time. We immediately thought this might make use of
resistor codes as the display
but it doesn’t. Red shows the hours, green for minutes, and blue for seconds. Now stack all of them on top of each other in binary and you’ve got the time. That means you’ve got to know all of your color combinations, plus read the binary value correctly, to decipher the time. Add to that the display changing every second and we’re in trouble.
Aside from the user difficulty level, this is a really clean build. It uses an ATmega8535 in conjunction with our favorite DS3232 RTC chip. The etched board is nice and clean, making for an aesthetically pleasing clock.

Works in chrome16 and firefox9.This was just a quick mockup, and as you see there’s a jump between each full minute, hour and day that isn’t too gracious (because of the values wrapping from 255 to 0).A version using hsl instead of rgb might be interesting, where hue, saturation and luminosity represent hours, minutes and seconds. If you instead bind hours to luminosity/lightness and make it reach 255 in 12h and then reverse the direction you’d have it darker during night and brighter during daytime.

Drawbot Produces Portraits… Very Slowly

This robot artist,
the Drawbot
, produces images using an Arduino and Processing. A piece of paper is attached to a wall as a stylus connected to a couple of stepper motors scribbles out patterns that gradually become the image seen above. Each drawing is different and can take several weeks of constant operation to finish. That must have made debugging a real problem for [Harvey] during development. We wonder if this would work with
homemade pencils
?

[Barry] didn’t want to deal with the voltages involved in using a Nixie display so
he built this clock to look like it has Nixie tubes
. He’s made 7-segment LED displays using some channel material, and mounted them so they look like they’re hovering above the clock base. Once everything was hooked up he added small glass jars over the top of each digit, completing the look.

For this each digit has ten acrylic panels each with a number etched into it, just as inside a Nixie you have ten anodes in the shape of numbers. To display a number you turn on a light bulb (nowadays you’d use an LED of course) directed at the edge of the proper acrylic panel; this would cause that number but not the other 9 to be illuminated from within. Back when I was a kid my father had a rackmount precision voltmeter that worked like that — and used mechanical relays and voltage dividers to seek the correct display point.",

WiMax Antenna With Auto-positioning System

[Andrew] certainly brings a bit of a James Bond feel to connecting to your WiMax base station. He built this
antenna along with an auto-positioning system
to get the strongest signal possible. The device, which appears a bit fragile, breaks down into a nice little case. When you get to your next checkpoint you can set it up and the stepper motor along with an ATtiny2313 will rescan to get you on with your mission as fast as possible. This is one of our favorite antenna builds so far, and we’ve seen
a lot of hacked antennas
. Don’t miss the action-packed trailer after the break.

Simple Way To Fix That Broken Ethernet Cable

"connector",
"ethernet",
"rj45"
] |
Chances are you’ve come across an Ethernet cable where the small plastic tab that holds the plug in place has broken off. We have a crimper on hand and usually just throw on a new RJ45 connector but [Laxap] found
a simple alternative to fix Ethernet plugs
. By using a couple of correctly sized cable ties you can secure the damaged connector without replacement. The boxy locking mechanism on the end of the cable tie is used as the catch, slimmed down with the help of an
X-Acto knife
or razor blade. Once you’ve got the right fit, use a second cable tie to secure it to the Ethernet cable. Simple is brilliant.

Windows 7 Tablet In A Carbon Fiber Case

If you’re not one of Apple’s devoted following the iPad means little more than new hardware you won’t use. Tired of being left out in the cold, [Slampana]
built himself a Windows 7 tablet
. He grabbed the motherboard and 13.4″ screen from an MSI X320, added a resistive touch screen, USB hub, internal WiFi and Bluetooth, then wrapped it up in a custom-built carbon case. It’s small, sleek, and comes in at around $600-$700. Start your drooling as you watch the demo after the break.

Nexus One As USB Host

[Sven Killig] Has managed to get his
Nexus One into USB host mode
. This allows him to plug in all kinds of peripherals such as web cams, keyboards, even a displaylink unit. This is fantastic as it really opens up the possibilities of this device. You can see that he now has an amazingly functional and portable system running. He mentions that it is pretty stable unless he runs big programs, we wonder if he has
added any RAM to it
. It is worth noting that the
Droid can be USB host
as well.

In this writeup, you can see how to
build a cheap compound eye system for your robot
. Using 4 IR LEDs and 4 phototransistors, [oddbot] gave “Mr General” the ability to follow movement in objects fairly well, assuming that they are within 200 mm. Being IR, it has the typical drawbacks such as sensitivity to light or overly reflective surfaces, but we like the idea. It is perfect for a nocturnal or low light robot.

More often then not, someone else did it 20 years before that.In 1976, I avidly followed published research which consisted of doing just this with simple logic, but minus all the proprietary razzle-dazzle.They were attempting to model fly and frog eyes using photo transistors, and were able to follow a variety of moving objects fairly well.Circa 1973 or so, someone discovered that you could pry the metal caps off early dynamic ram chips, and that they were affected by light. These eventually became the “cmos imagers” or CCDs we use now (well, technically a CCD is different, but close enough for discussion, as original CCDs were linear arrays rather than square matrices) and everyone knows how that turned out.Don’t get me wrong – I applaud ingenuity and research, and these guys obviously have figured out how to mate a CCD with a cheap processor and create an integrated subsystem. We need more and better building blocks to accomplish cool things with, and they’re doing it.Having said that, the formulas for tracking edges and calculating speed are pretty simple, especially at the relatively low resolutions and accuracy provided by the centeye chip.The 1976 researchers were using a 4×4 phototransistor array and were able to find and issue… wait a minute! Maybe I should get into this business… a baby AVR and a pinhole camera chip… hmmmmmmm. :)Nah, just an old guy trollin’. Carry on Centeye, and more power to you.

Augmenting A Cheap Android MID

We’ve been on the prowl for a low-cost Android MID that, you know,
works well
. We were originally excited by the Eken M001 but early reports about poor battery life, coupled with the fact that it only runs Android 1.6 soured our interest. [Carnivore] didn’t let those things turn him away, instead he
modified the M001 to meet his needs
. He added a USB hub and flash drive inside as well as a few additional connectors for external devices. He’s also inserted a front-facing camera and improved battery life from a 1600 mAh capacity up to 5200 mAh. This means he can now depend on 7-12 hours of use depending on the power saving features he chooses. This does come at a cost, he had to add room inside the case so he annexed a project box for the back cover. As you can see above, he did a beautiful job of making it look right, but it’s lost that thin-sexiness it once had. See [Carnivore’s] feature walk through after the break.

I have some questions, you seem to have moved the WiFi board to access a USB port that you wired to a hub I also want to do this type of conversion and I’m shortly getting a seven port mini hub which should provide a suitable board complete with the female connectors. Could you provide some more detail concerning the possible sites for connecting the hub. For instance there is a USB port provided by the Apple type port, it is wired to a male connector, does this mean that the port is all but useless as its main purpose is to sync to a PC?The problem that you are having with the Camera is probably due to the fact that the drivers are as far as i can make out “compiled” using options when the source is ported to run on a WM805 processor (ha ha or MW8505 according to which specification one reads). Anyway if one has to recompile the code to add extra USB and Camera functionality why not use 2.1 or 2.2 source?If there is an obvious reason could you let me know as I’m just starting to try and get a handle on this so any help I can get I will willingly take of give.Best,Peter G.",

This
mechanized table
automatically expands from seating for six to seating for twelve. We tried to capture the action with the three images above but don’t miss the transforming goodness in the video after the break. Alas, we’ll never see something like this in real life because it resides on a yacht worthy of
Robin Leach’s
attention. We wouldn’t have a problem copying the geometry of the tabletop pieces, but there’s got to be some serious design work to pull off the structure controlling the movement. No solid price is listed, but the creators note that construction costs are in the tens-of-thousands of British Pounds. We’ll stick to our
Ikea furniture hacks
for now.

The Superprobe
is a logic analyzer, multimeter, and much more rolled into a fun to build project. [Ben Ryves] didn’t come up with
the original idea
, but he definitely took a good thing and made it better. You can use it to test logic, inject logic into a circuit, read capacitors and resistors, test frequency, read the device address from 1-wire devices, and more. Interchangeable probes, choice of internal or external power, simple two-button operation, and a powerful PIC microcontroller at the heart of it all make this a fantastic tool for your electronics workbench. Check out the quality video after the break that [Ben] put together to show off the results of his tinkering.

Printing With Pressure

[
"Peripherals Hacks"

[
"arduino",
"carbon paper",
"pressure",
"printer",
"processing"
] |
The video of
[Thibault Brevet’s] printer
makes it look like he’s actually designed a vinyl cutter (watch it after the break). But at the end of the printing process you see that the top layer was actually a piece of carbon copy paper and the magic was happening underneath. The print head applies enough pressure to transfer the blue-ish printing ink onto the paper giving the result seen above. He’s driving this with an Arduino and feeding data using Processing.
[Thibault] left this link in the comments from
the LEGO printer post
. Shame on him for not
tipping us off
as soon as he posted info on this hack. Don’t underestimate yourselves, if you hack it we want to hear about it!

In truth, while we look at this site regularly, most of us won’t bother trying to build everything we see showen on the site.We’re happy just to file away the idea, perhaps thinking that maybe we’ll do something like that one of these days.I want to thank the HAD guy for providing the “secret sauce” in the description – namely, that the guy is using carbon paper to produce the image. Never seen it done in this manner, even though I already knew carbon paper was often used to transfer layouts to metal for cutting and drilling. It’s a neat trick.I have no problem with the HAD mix of old, new, interesting and “non” projects. A lot of interesting mechanical ideas have been rehashed for about 3000 years, and still get trotted out as new technology. That’s OK by me.It’s the same with electronics, or flying cars, for example. As long as the focus of hackaday is guys* who do stuff, we’re golden.* regardless of actual chromosome count, appearance and various personality traits.Haters gonna hate, you know?",

Real carbon paper is hard to find, and pseudo-carbon work-alikes based on tiny dye capsules don’t have interesting RF properties.",

So there was this very simple moving mechanism up front, pounding away and magically producing letters, while all the real magic was hidden out of sight – the font cylinder rotated behind the paper, instead of the traditional flat platen.Hey, in the early 1970s, that was *high* tech.Anyway, cool build!",

USBasp: AVR Programmer Based On ATmega8

We love our AVR Dragon programmer but it can be nice to have a cheap and simple in system programmer on hand too. The
USBasp
is one such programmer that uses and ATmega8 as its only IC. It requires just a handful of components and can be purchased as a kit, or etched and assembled at home. If you source your own parts the chip does need to be programmed which makes for a
chicken-or-egg
scenario. We’ve used the Parallel-port dongle (
schematic
) from Adafruit’s
Spoke POV
before. It’s basically just
a DAPA cable
and a few resistors, a ribbon cable (use and old IDE cable if you have to) and a parallel port connector can have you up and running in no time. This is also a great way to get a friend into working with embedded systems. Order parts for a few of these and give them away to your buddies.

Nixie-display Brings More Wiring Madness

"nixie",
"tube"

[Tim Anderson]
whipped up this nixie tube display
using epoxy-coated wires. He’s certainly giving the
wire-wrapped LED display
a run for its money. He ground the epoxy off the end of each wire using a Dremel before soldering them. We thought you could solder right through the epoxy but maybe not. Was this easier than wire wrapping would have been? We’d bet that because of the voltages wire wrapping wasn’t an option here. That board on the left is the 180V power supply for the tubes with an AVR chip running the Arduino bootloader to the right. After the break there’s a brief demo of data being pulled down over a serial connection. [Tim] also has some plans to add an atomic clock module to this setup sometime down the road.

And of course wire wrapping could handle the voltages, wire wrapping (if you do it right) has tons of contact area and is plenty for high-voltage. In fact, this type of stuff used to be mostly wire-wrap. Non issue, especially if there’s no high current.

Regular reader [Osgeld] built
a 1024 LED display matrix
. This is a proof-of-concept design and he admittedly has overloaded the components. Most notably, the 595 shift registers (
featured over the weekend
) are sourcing too much current if all eight pins are active. That’s easy enough to fix in the next design by moving up to cascading LED drivers. Instead of
soldering every connection in the display
, [Osgeld] soldered the components in place and then used wire wrapping to make the point-to-point connections. This must have saved him a ton of time and frustration. We can’t wait to see what comes out of this first prototype.

HID Crafting With A PIC And A Joystick

[Amr Bekhit] converted his
gameport joystick to use as a USB joystick
. Much like a
universal USB joystick interface
, this uses an additional microcontroller to talk to the serial bus while monitoring the controls on the stick. [Amr’s] discussion about creating HID descriptors is clear and easy to understand. What he’s laid out can be translated to any custom HID your heart desires. Give it a try with
that old peripheral
that’s been gathering dust in the corner.

I believe that originally they used to discharge capacitors that were charged by “writing” to the gameport, and it was care of the software to count the time these took to get back to a logic 0. This meant that the joysticks would drift a lot with temperature variations, and were quite inaccurate at best. this still stands true for the gameport adapters, though I suspect they use a Wheatstone bridge, with the joystick’s potentiometers as an element, to compensate somewhat. From the wiring in the picture it looks like the joystick potentiometers are set up as voltage dividers, with the wiper picking up a voltage between the extremes at the opposite ends of the potentiometer. This means that the positioning is more accurate, and less dependent on the actual value of the potentiometer itself, as long as its resistance is high enough to limit the current between the supply rails.",

Props go to [Michael Nash] for
establishing an interface
between
National Instrument’s labVIEW
and an Arduino (an example video using a potentiometer is above). Personally, from the one
time we were forced
to use labVIEW, we hated every second of it.
One reason it’s so terrible, is the
Data Acquisition Modules
cost well into the hundreds of dollars, yet the documentation and help resources are very scarce. By using an Arduino instead of the modules, the price and difficulty decrease a considerable amount. Which begs the question why has it taken so long to get a decent (and so simple) of a setup working?

"content": "wow, never thought i’d see a labview post on hackaday…just wanted to put in my 2 cents as a certified labview dev – it is NOT a hobbyist tool. Hell, its not even an amateur tool. labview is something that firms use for quick and rapid deployment of test programs or data acq. environments, without having to know much about programming or hardware. There are clients that dont know why they need labview, they just know that Engineering Firm XYZ uses it and is successful.I’m not saying i like it or enjoy using it, but cert’ed labview dev’s are in HIGH demand, and do pretty well from a salary standpoint.And yes, the modules and software are TERRIBLY expensive, but remember it is targeted at the professional sector. Hell, they have a USB to 4-port RS232 switch that is $500!Anyway, cool project!",

The IO modules get better resolution, much better speed, and it takes a LabVIEW newbie just a couple minutes to acquiring data.LabVIEW markets to a completely different class than the Arduino.

If you can’t think of anything that would be better suited by LabVIEW than a general purpose language, you’re not looking at the right sectors. Labview’s not for the hobbyist, at all. While Labview does have it’s faults, it’s sure got its strong points, and the hardware from NI is, for the most part, some of the best stuff you can buy. I would have to say some of the better features of Labview aren’t really available on other platforms- such as easy GUI creation (like “falling-off-a-log” easy) and the massively parallel structure that it uses. Sure, I wouldn’t program a cell phone with it, but we have a program we developed here at work that will completely test our piezo actuators, including frequency response.

"content": "As someone who, also, uses Labview as part of my day job, I have to agree with the other guys here. It can be a great language depending on what you’re doing with it. One of the things that, I think, give it a bad name is the fact that developing in it is a radically different experience that most, standard, languages like C, C++, JAVA, etc. Everything from how you structure you’re logic to documentation has to be done differently in order to be successful with larger projects. Basically, in order to successfully program in it, you have to think a little differently than with conventional languages.As for documentation and help resources, I have a feeling that you just didn’t know where to look. For most Labview compatible products (which is a large percentage of the data acquisition and automation industry) there is a lot of high quality documentation. Of course, it does vary some based on who the manufacturer is. As for help, NI runs a pretty active developer community, through their website, where you can go for assistance.",

That being said, there is LabView FPGA which I think is tailored to programming the FPGA in the cRIO backplane. I have found it quite straight-forward and powerful.As a counterpoint, there are times when I prefer to write code instead of wiring it. Writing equations with many variables can get cumbersome for example. So, for those situations I use a mathscript or formula node and write it all out with m-code format. I can easily access .NET libraries, use activeX, run arbitrary commands in the commandline, or whatever. Oh, one other downside is that it is really easy to write HORRID obfuscated code. You can make sections of your code literally transparent. That, I would say, is a downside.We’re hackers. If you’re whining about being held back by a mature programming environment, then I think you’re doing something wrong. For personal use I would not recommend LabView (along with NI equipment) due exclusively to the cost. But, I’d say that over the past 20 years or so, LV has proven itself useful (at least to those whose opinions actually matter) in data acquisition, machine control, data processing and logging, data presentation, user interfaces, etc.I am a Certified Labview Developer like several of the other posters, so I do get paid to learn the stuff.

We had an engineer (EE Masters degree) work for 2 years on a single Altera FPGA chip to control 16 video cameras at the same time. Using serial control and COAX control, which is PTZ control on the video line.After 2 years…..Never finsished it. I (AS computer tech degree) spent one day with a sbRIO and our custom interface board and had COAX PTZ control working over the network. And with NI help the rest of the application took a month to design.So how much does it cost to pay an EE for 2 years work and how much did it cost for a sbRIO and a month for me to work on the same thing….Anyways, I hope ill be seeing everyone at NIWeek 2010! i just signed up today for it.

The other complaints (lack of documentation, lack of help, no ability to comment, no ability to save settings, etc.) are all examples of people that don’t know how to, properly, use the tool.The simple fact is that it’s a graphically based data flow language. It’s a radically different paradigm than most programming languages. Personally, most of my computer science education and experience has been in conventional languages like C and C++.

"content": "Hi Guys, LabView is great. CompactRio is great. The prices are high as the licences and the hardware are very expensive. It’s a must for development purposes and instrumentation applications. For out-of-the-lab, real world scenarios, (i mean, production in series, high reliability, low power consumption, hardware simplicity) it can’t compete with a custom designed hardware (with cheap microcontrollers and DSPs) and software (with C/C++ code, assembly optimizations, etc.).Even for these real world applications, people usually develop in LabView (or in any other development framework, such as MatLab, SciLab, whatever) to rapidly create prototype solutions and test the main concepts behind it. These tools are required because they hide the complicated aspects of a data acquisition platforms, executive/operating systems, etc.After a initial/prototype design, people intended not to be stuck with NI tools forever, start porting the LV application to custom hardware. This porting is the problem. LV is not only a language, it is a real time framework comprising a real time executive/operating system (for embedded applications) and the real time runtime for the G language. This is where the madness begin.The G language is very abstract compared to C/C++ code as it can be executed in parallel, where the hardware permits. Directly porting it to other platforms requires the LV Runtime or C/C++ code generation tools (which still requires libraries from National) and a competent Executive/OS. The original prototype performance and results using the dedicated National HW/LV are *hard* to obtain on the custom HW in this way. The debugging of the generated code is insane. The maintenance either. The documentation of generated code is completely absent. The memory footprints are BIG. The program footprints are BIG. The code can’t be easily post-optimized by hand.If you *can* afford the National Instruments LV/HW related costs, if you think the National hardware is quite reliable, if you can afford the HW power consumption, size, housing, etc., if you can survive forever stuck to NI, PERFECT, you found the solution for all you problems, NI/LV is the yellow brick road to your systems. It only a question of living in or not inside a “National” shell.If not, keep using other frameworks, you FREE/STANDARDIZED preferred language, create you own toolbox of functions, routines, use and abuse of GNU tools and cross-compilers, code revision tools, version control tools, case tools, whatsoever.Maybe if National turns the G-language, LV and LV/RT to be FREE, open source tools, with tons of third-part hardware/software suppliers, if they adopt other languages inside its framework (hey National, didn’t you hear of IEC 61131-3 for control/automation, IEC 61499 ?), this could be a de-facto solution for us all !Greeting to all hardware hacking community!Eduardo Pellini",

"content": "Ha! Well this sure turned out to be a hot topic. ;) Guess I’ll chime in my 2 cents. I’ve used LabVIEW extensively. I’ve found its utility to be entirely related to the intended application. I think the power in it lies in it’s prebuilt modules. For instance, if you are building an instument test platform like a bed of nails and need to do signal analysis using a Fourier transform module it is a pretty good choice. If you are going to do sequential process automation for say a chemical vapor vacuum deposition oven, it is a royal nightmare. I think many people like it for it’s ease of use in creating GUIs. Funny how no one noted it’s worst attributes of all, those being difficulty in debugging and the inability to resume a defined program startup state after a crash. If you like watching signals “flow” over wires while debugging this is just the ticket for you.",

Really great tool (very expensive also) for that purpose. These softwares could be used for measures recording, but are probably not as good as LV for that purpose.For hackers, free equivalent solution may be Scilab/Scicos/RTAI (https://www.rtai.org/RTAILAB/RTAI-Lab-tutorial.pdf).

The design paradigm is very different from conventional programming and each program requires the labview runtime environment, but for those of us that don’t habitate in front of a computer for our office work, it works wonders quickly.

One of the coolest aspects of my job is seeing all the amazing things that people are doing with LabVIEW – stuff we never would have thought of. (like this example!) I’m happy to see all the discussion here too. Of course, I can’t resist the opportunity to share some of my own “insider” thoughts…LabVIEW was originally concepted to graphically represent the way many scientists and engineers (and even some programmers) think: with flowcharts. The vision is to empower the domain expert with a tool to get the job done – without requiring a CS background. Does this mean the data flow programming paradigm makes sense for every application? No…nor is it intended to. But can it help solve the engineering challenges that we (the scientific community) face every day? Absolutely. Our goal is for engineers to spend more time finding solutions to problems and less time worrying about how to build them.Yes, LabVIEW costs money. That’s unlikely to change in the near future, but I believe our customers see the value proposition. I think pRoFIT (above) said it best with: “So how much does it cost to pay an EE for 2 years work and how much did it cost for a sbRIO and a month for me to work on the same thing….” We’ve seen some prettypowerful demonstrationsof LabVIEW in other scientific endeavors as well.We know LabVIEW isn’t perfect. Our R&D team wouldn’t have much to work on if it were. That’s why we want to hear this feedback. Posts like this get circulated all over the company – trust me, there’s a LabVIEW R&D engineer reading this right now… Honestly,send us your ideas. In the meantime, I’d love to see more of you LabVIEW developers post your projects on Hack a Day!",

For those unaware, the little acronym above stands for Do-It-Yourself-
Direct-To-Garment
printing. In layman’s terms, printing your own shirts and designs.
Commercial DTGs
can cost anywhere from $5,000 to $10,000 which for the hobbyist who only wants a few shirts is ridiculous. So you would think this field of technology would be hacked to no end, but we’ve actually only seen
one other fully finished
and working DIYDTG. So we took it upon ourselves to build a DIYDTG as cheaply and as successfully as possible.
We would like to take this moment to thank [makemygraphix] for his original designs, as ours is heavily
based off his
. And
Tshirt Forums
, for their valuable input.
For your own DIYDTG you’ll need a few parts, (we honestly just used what we had lying around)
-3/4 inch particle board/plywood/MDF
-1/2 inch particle board/plywood/MDF
-1/4 inch plywood
-1 and 1/2inch wood screws
-24inch ball bearing drawer track
-scrap aluminum (1/16″ thick)
-Epson printer (more on this below)
The printer you choose is the most absolutely crucial part of this hack. We took apart an HP DeskJet 3845, Canon iP1500, Brother MFC420CN, Epson Stylus Photo 820 and an Epson Stylus c40. Why so many? We literally purchased every printer the local thrift store had (at $6 a printer, it’s not that bad actually), that way the reader wouldn’t have to. Our findings were thus; the HP and the Canon both had rotary encoders on the paper feed shaft and ended up being a total peta to try to align and get working, both not recommended. The Brother was an all-in-one that would not function unless every part was connected, making it too large and bulky for our needs. Both Epsons used stepper motors, were very easy to take apart, and only had one easy to manage paper sensor. Go with Epson! (We ended up using the C40 because it had the 3 ink CYM system instead of the 5 CYMLCLM system the 820 did).
As for the ink you will be using in your printer, we found
DTGinks.com
to be a good resource.
For software for your Epson, we found the default drivers worked well enough. There is RIP software out there, but we couldn’t find any that supported the c40. We will recommend the
SSC Utility program
though. Allowing you to quickly and easily lie to the printer about how much, what kind, and replaced ink cartridges (for Epson only).
For tools we recommend the following
-measuring tape
-square
-pen/chalk line
-table saw
-circular saw
-jigsaw
-Dremel
-drill press/drill (and an assortment of bits)
-sand paper/file
We started off by taking apart the printers. Every printer is different, so we can’t give you details but its relatively simple process. By the end you’ll only need the head and its carriage, the paper feed motor and its shaft, and the power supply.
You’ll need to cut the wood as follows, (it should be noted, these are slightly different then what we actually used)
For the 3/4 inch,
1 x 26inch by 11 and 1/2 inches.
1 x 26inch by 10 inches.
For the 1/2 inch,
2 x 26inch by 5inch,
2 x 26 inch by 1 and 3/4 inches.
First clamp the two 26″x5″ boards together. Now 6″ from the end and 2″ and 3/8″ from the bottom drill a 5/8″ hole through both boards at the same time. This is where your paper feed shaft will go.
Here is a tricky part, the metal track. We mounted the outer part 3/4″ from the top on one of the 26″x5″(doesn’t matter which you choose) pieces and made the stop/back/end of the track flush with the end of the board (this isn’t very high priority) . And the inner part of the track goes 1″ and 1/8″ from the top on one of the 26″x1 and 3/4″ pieces.
Normally we do recommend that you use metal “L” brackets to attach corners of wood, but as long as you pre-drill a hole slightly smaller than your screws, you’ll be fine (we also counter sunk most of our screws, but that’s optional). Attach the two 26″x1 and 3/4″ to the 26″x10″. Do the same with the two 26″x5″ and the 26″x11 and 1/2″ pieces.
All that was a little tricky, so here is a picture to help out. For those wondering, the top tray rolls “towards” you in this image.
And a shot without the top tray, as you can see our shaft wasn’t long enough, so a simple 2″x3″ piece was put in place. Make sure the shaft spins freely and without binding, with and without the top tray in.
The next interesting part is mounting the drive motor. It needs to be snug against the gear of the shaft, yet not too tight to make it grind against the wood. It also needs to have a way of preventing the shaft from “popping out”. We solved both problems relatively simply.
Take your assembly, remove the top shelf, and prop it on its side. Position your motor where it will be mounted on top/inside the 26″x5″ piece. Drop in the shaft, get everything aligned and draw a circle around the motors base. Using a straight edge and tangent lines you can approximate the center of your circle.
Use a large hole saw cut it out (it doesn’t have to be perfect). Sand/file it so the motor easily fits in without bending any pins. We pop riveted a 1″x3″ piece of aluminum to the motor to make mounting a little easier.
Drop in your shaft and make sure everything lines up. Finally, to prevent the shaft from slipping in, we used the washers and C clamp from the extra printer parts (you didn’t throw away, right?) on the other 26″x5″ piece. And to avoid the shaft from slipping out we took a 1″x10″ piece of aluminum, bent it in a “_n_” shape, drilled a hole for the shaft, and used a cut up spring from the extra printer parts. A picture is worth 1000 words,
Bare with me, we’re almost done!
You’ll need to modify the printer carriage now, simply cut off the slot that paper used to come through,
You’ll want to mount it on-top of the two 26″x5″ pieces about 6″ back. We were lucky and found two of the previous mounting screw holes on the carriage fit perfectly, however other printers you might need to bend or make your own. (This picture taken before we made our nifty “_n_” bracket).
Now we made our platen, this is the thing your shirt goes on. It’s really up to you how its made, and we’re not even totally happy with our design, so play around and find what works best. Ours is 24″x9 and 1/2″ piece of 1/4″ plywood mounted to the top of two 20″x2 and 7/8″ pieces of 1/2″ plywood. The height measurement completely depends on the height of your head. For those wondering, we never got an answer for how far the shirt should actually be from the head, but we’ve found about 1/8″ works well enough. (The “legs” you see on our platen were later taken off.)
Mount your power supply and solder it, alongside your motor, to the driver board.
Now there is one part we’ve neglected to mention until now. And that is the paper feed sensor (remember that one sensor we mentioned earlier?). Well it’s because we spent 3 days trying to get that sucker to work with our platen. We tried everything, different timings and positions of the platen, even programming an MCU to try to trick the printer into thinking the platen was paper. In the end, we just broke it off.
By accident.
And it worked (no really!) It takes a little timing on our part but by hand to trigger the sensor, but we’ve never had a misprint like we did with the platen. (Pictured below, one of our “tape” attempts at triggering the paper feed sensor, this one worked about 1 out of 50 times).
Powered on,
Send a print job, hand trigger the paper feed sensor, and we have a print!
Here is just a short video if it in action, most notably you can see us hand triggering the paper feed sensor. The orange was a test print, as you can see if your platen isn’t 100% flat and level relative to the head, you’ll get some smudging and general print errors. The white shirt was a perfect (well, test) print that we did a little earlier.

You don’t waste it doing vector images, or compressed images, simple logos. Leave that to airbrushes or screen printers.Anyway, there is a reason for (some of) the cost. For one thing, custom ink. It took years of back and forth with the DuPont ink guys. Another thing is multiple passes. Also, DTG printers often use multiple passes of the same image. Both of these are to prevent one thing: Quick fade out. Screenprinting cracks after multiple washes. The aim of the DTG industry is to produce garments that fades no faster than the garment itself. Dunno if they are there yet.Oh yea, our paper feed was wired to a button as well. An important tip: If you plan on doing bulkier items like sweatshirts, put in a laser sensor to stop the machine if something is high enough to hit the head. Those bigger items are harder to get completely flat, and you DO NOT want to have to waste time cleaning the heads by hand of fabric.",

We’ll be sticking with light colored shirts.@Eric W: Everything.@JohnSmith: We tried printing with regular printer inks, and as recommended DTG shirt inks. The regular washes out and leaves a lovely green stain. The DTG has yet to come out from wash! (We heat pressed both.)If we get enough demand, we’ll write up a tutorial on how we replaced the inks in our cartridges. Its different for every printer though…@mcmasterp: The white thing is just 1/8th inch thick cardboard because we miss-measured the legs of our platen. It helps put the shirt closer to the print head.@notahack: We can print in full color.@Doug: We lost a leg during the mod, we found it promptly later, but still be safe.For the winged HaD logo, you can thank Asyrum,http://i14.photobucket.com/albums/a335/asyrum/wordpress/hackaday-asyrum-3.pngJakob GriffithHackaDay Team",

Keep air moving to avoid blistering. Apply heat until paint is warm to the touch.Shirt Press: 325°F for 15 –20 seconds.Iron: With a protective cloth over paint, set on high/ cotton setting and iron for @ 2 minutes. A shirt press or iron is recommended for curing t-shirt artwork intended for washing.Again using createx paints is just an idea I had as an artist that uses them to airbrush. They come pretty thin already, as they are meant to be sprayed through a .5 mm tip @ 40psi. I do thin them for my .2 tip and I, of course, have no idea the size or manner that a printer head uses to expel it’s juices or if it could even throw paint rather than “ink” but @ about 4$ for 2 ounces of paint that is meant for fabric it would be a good thing if we could get it applied this way. The pigment is very fine and I think it would be very possible.The only downside I can think of is tip dry where the paint dries on the tip of my brush, or print head in this case, requiring a wet brush wiping the dried paint off now and then. Though I only have to clean the tip a few times during a whole helmet painting and I figure it could make it through a tshirt graphic without problem but a wipe of the heads after its done would probably be in order. Then again tip dry occurs because of the air pushing and drying the paint as it’s expelled and again I have no idea how a print head spits but I know it’s not compressed air so it may not tip dry at all.As for light colors on dark fabric; reversing and printing a negative is a great idea of course. But if the printer could indeed throw this paint one could very simply fill their black cart with white paint (or anything) and just let it spit the white onto the black shirt as if it were full of black.Well, I’m rambling lol that’s just my input =)",

The Intelligent Ground Vehicle Competition (
IGVC
) is the precursor to the DARPA Grand Challenge, and in many ways it is just as difficult. We have the pleasure of being at the competition this year with the Tennessee Technological University Autonomous Robotics Team. The teams at the competition pull off some amazing home-brew robotics, so we’ve decided to do a short section on some exemplary robotic hacking each day of the competition.
Today’s robot comes from the York College of Pennsylvania. The robot, dubbed “Green Lightning”, features an impressive set of custom made hardware.
We interviewed the team, and got a pretty thorough rundown of their robot with pictures after the jump.
The spinal cord of the robot is this custom built beauty.
It consists of six layers, each with a specific function. The boards were designed by the team and fabricated by
Sunstone Circuits
. Each layer except for the top has its own
teensy++
unit, programmed in C, providing an SPI interface to the hardware it’s designed to connect to. The first layer has an Arduino Mega programmed in C on it. The layers communicate with the Mega through an SPI bus running at 500Kbaud. The Mega processes the information and then communicates to a computer through a 1Mbaud usb serial connection.
The remaining five layers are each designed to interface with a specific section of the robot’s hardware. The second layer communicates with a
Wheel Commander from Nubotics
, simplifying the robot’s motion controls.The third layer is the interface to the robot’s emergency stop. The rules require that there be a visible hardware e-stop on the back of the robot and a wireless remote e-stop. They solved their wireless e-stop problem with a zig-bee module that connects to the robot through this layer.
The fourth, fifth, and sixth layers all connect to the robot’s sensor groups. The fourth layer is the interface to their gps, mounted at the top of the robot. Most gps units communicate with simple serial and it’s pretty elegant that they managed to save a usb port by adding a board. The robot has nine
Sharp 2Y0A710 distance sensors
acting as a short-range bumper for obstacle avoidance which all connect to the fifth layer. The final layer is the interface for 10
long range sonar sensors
located at compass points around the robot.
The robot also has two USB Web Cams for line and object detection mounted on the mast. The AI and computer side hardware interface is programmed in a mix of C and Java. The AI follows a reactive model instead of a mapping/planning one which has been proven to be very effective in this competition for many teams.
The frame, track, and drive train were custom built by the team as well.
Here you can see the back of the robot where the drive train, Wheel Commander, and two
SaberTooth motor drivers
are.
A side shot shows their track system. They modeled it in SolidWorks first and then fabricated everything including the belt in house.
In the end the robot cost them around $5,200 after discounts which is pretty impressive considering its capabilities and that some of the robots at this competition easily break $50,000 dollars. It’s a prime example of what good engineering and home-brew magic can accomplish. We’ll finish with a shot of their manual control system.

For example . . . because the speed is govern to 5 mph and knowing position is important, why risk other tasks and sensor readings for encoder reading? Knowing your position is just as important as knowing your speed or knowing if there’s a wall in front of you. The separate layers allow the particular layer worry about all of the input of that layer and processing to get a usable output. EG reading all of the voltages from the proximity sensors and converting it to inches instead of all of the software worrying about voltages.",

"content": "So, let’s clear a few things up just to let people know some info about how everything fits together. First off I’d like to say thanks to the author of the article cause they really gave us some good publicity and showed off what we did very well and for that we are very grateful.To address the e-stop concern, yes, this absolutely had to be a separate system in order to even qualify for competition. These rules are very stringent and if not met you are not even allowed on the practice course. From an engineers standpoint think of it this way, if it was on the same processor as everything else would you want the vehicle to stop before hitting you at five miles an hour or be delayed because of a “toggle LED” command and break your leg? And believe me, it would cause its heavy and moving quick.The software was programmed in multiple languages for a number of reasons. C is very simple to program the microcontrollers in and also executes very efficiently. Also, programming in Java for an embedded system is difficult as compiling for java is typically done using JIT compilation. This would overwhelm an embedded 8-bit processor. Java however does run well on a multi-core pc which we used for image processing and navigational algorithms. And doing image processing on an embedded system would be near impossible as the processor would not have the necessary resources to accomplish this task in a timely fashion.And no, the code for these robots is not a bunch of IF’s, it is code designed by computer science majors and computer engineers who have studied algorithms and considered many possibilities. If fact our robot created a map of it’s environment to navigate.There are layers because each subsystem is created by a separate student as their project and while it could be programmed on the same hardware and merged later, why not have a common communication protocol you know you can use and then just work off a common platform which acts as a “plug-and-play” system. In this manner our system was built by individuals, combined in the end when it was time, and if any system were to fail or be incomplete the central controller would shut it off and compensate with what is has and continue. Besides, the way we designed it allowed for parallel processing with a central processor simply collecting data and throwing up to the PC which made the decision as to how to act, send the decision back, after which the central unit communicates with the required hardware to execute what’s needed.There’s more I could say but in short it’s a hard competition which requires hard work and many considerations. We chose to think economically and outside the box using handmade components. In the end we had a well mad secure structure made by an interdisciplinary team. And if you think it’s overkill you should see other teams. Anyway, thanks for looking at our project. We worked hard and I think we did well.",

Automonous vehicle design is no small task, and your team got something out the door which was not only functional, but seemingly fairly rugged as well.This takes the professionalism up a notch from some robots/hacks I’ve seen which look like they have a 90% failure rate even with frequent operator intervention.I’ll be leaving soon for a robotics competition myself, so I can appreciate the reasoning behind some of the points you raised.Please try and be a little bit less defensive. It hurts your professionalism and comes off as insecure.If you’ve ever published on social media before you should realize that armchair quarterbacking/sneering goes with the territory most of the time.The ammount of embedded systems at first impressed me as slightly redundant/overkill, however I don’t presume to know the entire list of design constraints & engineering considerations which ultimately lead to the path you took.For instance in my robot: we have a number of PIC based microprocessors being controlled by a microcontroller which interfaces with a laptop.It may have been possible to make a single do-everything board but it begs the question: why bother? The current solution gets the job done and we have more pressing concerns than making a proprietary board for bling factor.",

[Shoji] has a beloved sequencer that went out of production ten years ago. Unfortunately the storage options are also 10 year out-of-date as SCSI is the stock option for storing his loops. Using a series of adapters he
added Compact Flash storage to his Akai MPC-2000 Classic
. The board has a connector for 25-pin SCSI which he wired to a 25-pin to 50-pin SCSI adapter. From there he connects a SCSI to IDE board, and then an IDE to CF.
Subsequent versions of the
Akai
Classic have floppy drives in the front left corner so he used this method to mount he CF slot. Now he’s got plenty of storage with very little change to the appearance of the looper.

[Webca] has made a
3D printed MakerBot
with his MakerBot. Using five pounds of plastic, the design replaces all of the plywood used to create a regular MakerBot. This complements the existing designs for the 3D printed extruders, dinos, and other parts already on
Thingiverse
. An interesting mile marker in the history of 3D printing. We might make one after we make a Mendel and tons of
Hack a Day Badges
. We also look forward to improvements people will contribute to the design such as using less plastic or a parameterized design to make a really big (or small) MakerBot.

We received a very interesting “hack” today from our good friend [Jonny Dryer] that really got us thinking, but first a little background.
For those that live only inside of a box on top of a mountain (we know who you are), there was an
explosion of a British Petroleum oil rig
about 40 miles southeast of Venice, LA. Being proclaimed by Carol Browner as “probably the biggest environmental disaster” – stated a month
after the accident
.
And the oil is
still spewing
. Now, we’re not ones for criticizing how this event is being handled; no, we left it
to the
experts.
Back to our point, [Jonny Dryer’s] sent us
his plan for slowing the oil spill
, by using liquid nitrogen, pretty genius if you ask us. And we were wondering what possible solutions other readers had come up with? Share your thoughts on this situation in the comments.

I think this is also how they keep the oil in while drilling new wells. They did try pumping mud back down, but could not get it deep enough to make a column that equaled the well pressure, so it all came back up.",

Some of the ships that they used in Dubai were the size of oil tankers that could drop the full load inside them filled with rock and gravel within minutes. It wouldn’t take long to bury the well with so much rock that both the weight and the restriction of the flow would slow the flow down so that something like portland cement could be used which hardens under water. Or use large granite slabs of rock. The oil pressure is not great enough that it can push 2-300 ton slabs off of it.Rock is what keeps oil in the ground naturally so why not use it to stop this leak ?

They don’t even let you fish off their rigs ffs. They KNOW that accidents on rigs or deep undersea are much more costly than any potential profit gained by hasty or unplanned actions.As for the LN plan, it sounds interesting, but I think that the cooling is probably too slow, even if the engineering issues surrounding the proposal could be overcome. a massive concrete box, that would sink into the seabed a few feet, and had a conical roof to allow the oil to be siphoned off the top, is probably the best brute-force, quick solution.

The fight in which as stated by Trans-Ocean, BP accepted all responsibility for the removal of the drilling mud from the hole.Mistake #1: BP decided to remove the drilling mud from the hole. Drilling mud in this case is one safety measure that was in place.Mistake #2: The cement job on the hole was botched. Ships near the rig got showered with cement.Mistake #3: Some idiot drilled a hole in the blowout preventer, which I suspect was partially closed and malfunctioning to begin with. (chunks of rubber was ejected from the hole)Solution #1:A water well drilling manual states in a situation like this: they need to put a pipe into the well with a screen and dump lead bearings/shot down the well. That would stop the well up by increasing the resistance to fluids moving up the production pipe.Solution #2:There is a flange on top of the blowout preventer that has the old pipe still attached to it. Un-bolt the old pipe from the top of the blowout preventer and put on what is called a “tree” on top of the pipe and bolt it down. Then close the valve on the tree. Then cement the hole shut. Replace the blowout preventer. Then, drill out the cement plug and put the well into production.In short BP violated policy by removing the drilling mud from the hole, and in doing so they removed one of the safety measures in place to prevent this from happening.",

If it doesnt go up then it will go the path of least resistance. I do think it would slow it down though.If I had to come up with a solution I would go the bomb route. Not a nuke or fission or whatever that would radiate everything but a shaped charge down the center of the pipe. When it is well below the seabed, like halfway between it and the oil resevoir detonate it. The pipe and the surrounding dirt/mud/rock/earth/whatever will implode plugging it up. There will still be a leak like I mentioned above but it will slow it down enough for a proper cap to be installed and the relief well to be dug.Like I said, I am not smart so something like this might not work but I would think it is a better option then golfballs.",

Motorcycle Current Gear Indicator

[Vassilis Papanikolaou] just finished building
a gear indicator for a motorcycle
. This quite a simple implementation compared to some of the
other vehicle information displays
we’ve taken a look at. You should be able to build and install your own without breaking the bank. An ATtiny25 microcontroller reads data from a couple of hall effect sensors and the neutral switch, then displays the current gear on a 7-segment display.
There’s a magnet on the shifter and two hall effect sensors at the position for ‘gear up’ and ‘gear down’ shifting. The AVR chip keeps track of these and even stores the last position in EEPROM when you shut the bike off. If the device somehow gets off track, it will automatically recalibrate itself next time you shift into neutral, thanks to the bike’s neutral sensor switch.

The only cure will be to find an easy way to read the shift drum’s actual position.-If you want to create something truly useful for a lot of riders, how about an easy way to make a bike’s turn signals self-canceling, after both sufficient time and distance have passed.

[Tim Williams] likes to heat things up with
this induction heater
he built. At peak it can use 1000W and as you can see in the video, that’s more than enough power to heat, burn, and melt a plethora of different objects. The case design uses a center divider to isolate switching noise from the magnetic field with the whole unit housed in aluminum because it won’t heat up from stray magnetic fields. He’s selling plans and kits in case you want one, but we just don’t know what we’d use it for.

Most common is zinc poisoning, which can be fixed by drinking whole milk. Be prepared, you will throw up after. The proteins in the milk absorb the zinc from the galvanizing and you get it our of your system by throwing up. Trust me if you are suffering from it, you will throw up, no choice. I suffered from this while in the Air Force working on some material that had to be brazed. Hospital sent me home with orders to drink as much whole milk as I could and didn’t warn me about what would happen. Next day I was feeling better and went back to complain and was told that it is a normal reaction, they didn’t inquire at the time if it was my first time with zinc poisoning. Keep clear of the yellow-white fumes and whatever you do, do NOT breathe in the white feathery pieces, they will make you more than just sick.Warning to the wise.",

Heat treating anything with something that powerful would be overkill (and frankly require more skill with perfect timing than I have, since the temperature required to temper steel is < 600 degrees), but it would be perfect for heating steel/iron to good working temperatures very quickly. Ideal for bladesmithing.I would vote that unless you know exactly what you're doing, stay away from heating/welding galvanized steel. The risk isn't worth the reward – particularly since you loose the benefits of galvanized steel when you do heat it to that point.Plus, since it's a heavy metal, the effects will add up over time – a hundred small doses can kill you as effectively as a single large dose.",

You are correct that tempering is done well below 600 but the initial hardening requires temps from 1200 to near 2000 depending on the alloy and hardness required. Something for which induction heating is ideal and indeed for which it has been used for many years. Besides the relative ease and quickness over using a forge or kiln, induction has the added benefit of being able to be tuned for surface hardening which results in the equivalent of differential tempering and indeed obviates the need for a tempering phase altogether.",

I also melted cast iron. :)Some comments on comments:I took adequate precautions when heating the galvanized pipe. Obviously, you can’t see my face, but I was wearing a mask. I also left the area for several hours afterwards to let the fumes clear out. I know personally that I am practically immune to zinc fumes, so it doesn’t seem to matter much for me. Some people are dangerously allergic to the fumes, so you should never be careless. It’s bizarre how zinc fumes seem to affect different people so differently, and anything so curious is sure to draw lots of comments…@Ulrich: that seems to describe the LLC output network, which I decided earlier (page 7-8 on my website) sucks, at least for the values I was using. This setup uses an output transformer and series resonant tank, which operates much more smoothly. I used a TL494 oscillator, which is similar to the SG3524 (the 3525 with uncommitted transistor outputs instead of totem pole outputs).Tim",

PartKAM is a
Flash-based CAM production package
created by [Jack Qiao]. There are a ton of computer aided manufacturing suites out there, this one is simple and requires nothing more than having your browser open. We played with it for a few moments and found it useful but still a bit buggy. Most notably, it lacks a ‘undo’ option. That being said, you can export as SVG or gCode for use when you just need to
hammer out a few parts
with that
CNC mill you threw together

Got a bag of LEDs handy? Why not build a display with them? We’ve seen a lot of clocks that make use of LED modules but soldering your own is a fun pastime. [Vadim Suhovatih] did just that using
130 LEDs to build this clock
. Each segment of the 7-segment digits consists of three LEDs in parallel which are switched by some 2N4401 transistors. An ATmega328 in the form of an Arduino controls the device with the aid of a DS1307 real-time clock for timekeeping and a 4017 decade counter to assist with scanning the display. Check out the demo after the break.

[Squirrelfantasy]
built a printer using LEGO
pieces. It’s not a Mindstorm project but instead depends on some type of development board and some auxiliary components on a protoboard. We couldn’t get a good enough look to tell exactly what makes up the electronics so start the debate in the comments. We feel this is a printer and not a plotter because the stylus moves on just one plane while the paper feeds past it but that’s open for debate as well.
Guess this answers the question of
why aren’t we building our own printers
? Some folks are.

There were a couple short Arduino tips in the mailbox this morning. We’ve combined them in this post since both are fairly short and sweet.
Over at Evil Mad Scientist Laboratories, they’ve posted a quick breakdown of
how to interface those neat little HDSP LED displays with an Arduino
. This specific instance is for
Mr. Stabby
. Source code and schematic are included.
For those who would like a nice familiar input device for their Arduino,
how about a Playstation2 controller
? [Bill Porter] has written up the code and shown how to wire it up. This even includes the ability to read the analog stick correctly. Source code and schematic are available on the project page.

[Arkos] gutted an RC car from his childhood and made it into
a dog-taunting remote platform
. An Arduino replaces the original circuitry with a Bluetooth module for connectivity. He uses an Xbox 360 controller and has added a small speaker to act as a siren. But for our money it’s the camera that makes this hack. It streams video back to a laptop and because it’s mounted on a couple of servos the left stick controls where the lens is looking. The next evolution should replace the Arduino for
a standalone microcontroller
but what he’s come up with as a first prototype is delightful. See Fido run in terror after the break.

Modern Recordings On Wax Cylinder

"wax cylinder"

If you thought you’d never have a chance to release your hit single on the wax cylinder think again. A band obsessed with the Victorian era did just that, having a DIY’er produce the cylinders for them. The
story was covered by the BBC
and includes a lousy attempt to build a phonograph to play back the recording. The video shows their craftsmanship (or lack of it) but it’s not even in the same realm as
the masterpiece we saw last September
. You do, however, get to see the production equipment used at about 2:45 into the clip.

[Brian McNamara] fed the output of his guitar pedal back into its input creating
a looped synthesizer
. He started with an effects pedal he made but now we think he’s ended up with an electronic
stomp box
. Check out the results in the video after the break. Now he needs to make the knobs foot-friendly so he can monkey with this while playing guitar.

[Matt Evans] was running up against the common programming gotcha caused by disappearing parallel ports. For years he had used a JTAG parallel cable when working with FPGAs but recently realized he no longer owned any machines with that interface available. Instead of shelling out $50 for a USB programmer
he a programming interface from an old router
.What he’s doing is
bit-banging
using Linux. In this case it’s a router running a version of Linux which makes his setup Internet friendly but this could be done in the same basic manner on any Linux device with enough available I/O to connect to the device you are programming.

For JTAG, though, these delays might be tolerable. Still I remember a special LPT programmer for Atmel AT89C* microcontrollers offered in their appnote (it had a few latches etc because a lot of pins must be driven simultaneously). That thing worked flawlessly under plain DOS only. Try under Win95 and you’re screwed most of the time.A bit more about adapters. I recently needed a plain (TwinAVR-type) programmer and the only capable PC sits in the attic long ago. The idea was to choose PCMCIA, not USB: my older laptop worked flawlessly with a PCMCIA-RS232 adapter (apparently a true 16550 directly wired to the system bus), even a particular timings-demanding software was happy. Eventually I bought a ExpressCard “parallel printer” adapter. Guess what — it didn’t require any drivers and automagically popped up as “USB printing support”! Oh, the irony! The thing is in fact designed for bulk transfer and incapable to return status bit more frequently than a typical printer would provide (and it’s lots of milliseconds).Just checked: expresscard.org says “ExpressCard technology uses a simpler connector and eliminates the CardBus controller by using direct connections to PCI-Express and USB ports in the host”. So perhaps I was simply too gullible to miss such an important hint. On second thought, the package says “no IRQ or I/O address required” which is even more suspicious because a classical LPT is unthinkable without these.",

IRobot Gets Awesome Exploding Rope Thingy

The
iRobot Warrior 710
is shown here touting a new toy called an APOBS or Anti-Personnel Obstacle Breaching System. The system is comprised of an explosive rope pulled by a rocket. We know that sounds pretty awesome, and you can see in the video that it is, in fact, pretty awesome. We don’t condone violence, or war. We do, however, love
blowin’ stuff up
. This footage was just so pretty, we thought we had to share it. What’s even more amazing is that these guys aren’t battling Apple over the name iRobot.

They carried around this pack, set it down and aimed at the obstacle, when fired a cord with C4 or other plastic explosive in it would launch to lay on the obstacle and detonate. Basically the military put 2 and 2 together and threw the pack on top of a robot.I’m glad to see that everyday we are deploying more robots to disarm explosives, and clear obstacles, it helps our boys out whilst keeping them out of harms way.",

Switchmode LED Flashlight Upgrade

] |
When [Neelandan]’s cheap flashlight’s internal rechargeable battery died, he scrounged for a replacement. Ultimately, the brightness of the light suffered with his new battery, taken from an old cell phone since he had dropped the voltage a bit. Upon inspection he saw that he would have to swap the individual resistors for each lamp to get the desired brightness again. This wasn’t really acceptable as he would have to repeat the process if he used another re-purposed battery with different specs. Instead, he
added a new circuit to supply constant brightness until the voltage drops below 2.7 volts
. We love to see hardware resurrected, even if it is just a cheap LED flashlight.

The
PhorsePOV
by [Julian Skidmore] almost slipped by, but we thought it was a nice easy hack for your Memorial Monday. The gadget uses an ATTINY25 to drive 6 LEDs
aren’t standard characters 7 units high
? Which when
waved in the air
produces a readable message. What we were really interested in is the use of a single button for text entry, called Phorse code, or an “easier to learn and remember” version of
Morse code
. While it seemed silly at first, most of us here could enter messages within a few minutes of trying.

Beginner Concepts: Cascading Shift Registers
|
Mike Szczys

] |
[
"beginner concepts",
"hc595",
"shift register"
] |
There’s a million tutorials out there describing how to use shift registers. If you’re just getting into embedded systems you should know how to use them as they allow you to take three microcontroller pins and expand them virtually without limits. This is due to the serial-in parallel-out nature of these integrated circuits. A key feature of these chips is the ability to overflow, or cascade to the next chip which is what provides the expansibility.
Protostack just published a tutorial that uses this hardware to
interface sixteen LEDs using two shift registers
. The explanation is short and to-the-point with easy to understand code examples. There’s also something to be said for their crisp and clean breadboarding work.
Take a look at how they do it and then use the concept to
make a fancy clock
or reduce the pins needed to
drive a display
.

Bluetooth Boombox

[Nathan] took this boombox and
outfitted it for Bluetooth streaming
. He took a Motorola DC800, which is meant to make headphones wireless, and connected it to the stereo inputs. The controls for the Bluetooth module were routed to the stock tape deck controls and a little bit of frosted spray paint adds a blue glow to the cassette window. Now he can stream music from his phone, including internet radio, which he’s done in the video after the break.
Did he find the most annoying demo video music ever? You be the judge.

Turn your volume down and take a look at the
brick sorting robot
in the video above. It’s built using LEGO and powered by four different NXT modules. It sorts differently colored bricks on the intake conveyor and places them on three output conveyors. The build is solid and was [Chris Shepherd’s]
impetus for starting a blog
. We appreciate the pneumatic tricks that he detailed in some of his earlier posts such as
a compressor
,
pressure switch
, and
air tank system
. His advice is “build, build, build” and that’s what you’d have to do to perfect a monster of this size and scope.

Flight Simulator But You’re The Plane

"Wearable Hacks"

] |
[Rafael Mizrahi] built
a flight simulator that lets him fly like Ironman
. As you can see in the video after the break, the hardware involves an automotive crane, hang gliding harness, plus the wings and tail from a UAV. A giant fan pointed at the wearer allows him to use the wings and tail to maneuver while the Wii remote strapped to his chest tracks the movement and feeds it to Google Earth Flight Simulator which is seen through the head-mounted display. We’re used to seeing
intense flight simulators
but this is something completely different.

[Sam Seide] dropped us a line about
his new arcade creation
. We loved his Punch-Out build that used
a punch dummy as a game controller
. This time around he’s made some mini-cocktail style MAME cabinets. He removed the screen from a netbook and placed it face-up underneath the acrylic bezel. There are controls on either side for two players as we would expect from any
quality cocktail cabinet
. The control panels are interfaced through the now familiar iPac boards and are a bit unfinished on the underside but that doesn’t decrease our need to see one of these on the coffee table at home. Check out demo and an outline of the parts inside after the break.

Crossfade Curve Tweaking

"trimpot"
] |
Tired of the disappointing performance from the crossfader on his Numark MIXDECK, [dj JD] cracked it open and
made the crossfade curves adjustable
. It’s a super-simple hack that just introduces two 100k trimpots to the crossfade slider. The change led to a higher volume level on the current channel until the slider was much nearer to the center. The added adjustment feature might be nice to have as two more knobs on the board but [JD’s] method leaves his equipment with a stock appearance. Is this a more refined version of
circuit bending
?

Using the switch, you only have the option of a harsh slope for “scratching” or a slope that fades out the channel you’re playing before the channel that you’re mixing in reaches it’s full volume. Once you add the pots to the cross-fader, you can create a slope that behaves anywhere between those two settings. Let me know if this was helpful.",

Being able to see what you’re doing can be the hardest part of drilling the through holes in those freshly etched printed circuit boards. We don’t know why we didn’t come up with this, but [Markus Gebhard] solved his shadowy woes with his
20-LED Dremel light ring
. Honestly, how many times have we seen
lights rings in photography
without putting it together that a light ring is perfect for this purpose. So kudos to [Markus], now we’ve got to go and dig up some surface mount LEDs and
uncork the copper chloride
.

Moving Speakers To Mix Audio Tracks

"processing",

"speaker"
] |
These speakers
play different audio tracks depending on which orange square the sit atop. They’re RFID aware and the orange tiles are tags. If you get tired of a track just move the speaker to a different one, or place the speakers next to each other to play the same song. We’re sure there’s a project for us here, it’s just going to take some thinking to figure out what we want to do with it. But the concept is certainly intriguing. Check out the video demonstration after the break.

This way the sound continually plays and you don’t have to constantly move the speakers.It’s certainly an interesting idea, it kind of reminds me of the physical trackers people have built in which you control what sounds are played by placing objects at different locations. one thing that was noticeable is that a couple of the tracks didn’t “mesh” well, they were using different beats and it just sounded awkward it would be interesting if you could incorporate a way to decently mix tracks but that doesn’t seem to be the goal of this project.Cool stuff though.",

As you move through the site, your head phones play the music and dialog automatically changed with each exhibit, with now bleed over between display. Cutting done on noise confusion in such exhibits. I think you have a money maker there:) This would be really great fro Trade shows. With IPods, you could set yours to share the song you are listening to with a fried. You could use it to share play lists and any other data that you want to share. Oops, here come those security concerns!:O I can see a new type of DJ Play Board being made, with controllers being moved around instead of Speakers. Dancers could use this in a beautiful way on a stage. Kind of like the old Dancing Squares Game. But way better! You could use Bird Sounds, Animals, Nature to compose a musical Floor. The possibilities are endless I think!:) Personally, I would like to hide on in my cap or shirt or jacket… And then secretly install my favorite music in every Elevator, Doctors office and any where that they play music for the Public in the World!;) Then where ever I go, I get to hear what I like!:)Don",

Parallax RFID Reader For Ten Bucks

We received a tip about Radio Shack putting
Parallax’s RFID reader
on clearance for around $10. The only reference we could find that indicated Radio Shack sold the reader was a
review page
. The reader originally sold for around $50 in the stores, so getting it for $10 made it worth a curiosity trip to a local Radio Shack. The store we visited did not have the reader marked down in the drawer, but it rang up for $9.97. It is too bad that the reader was so expensive in the first place, otherwise Radio Shack might still be selling them at full price. This is by no means a promotion, we just though we would share the information in case you were interested in getting one yourself. If Radio Shack is out, you could always
build your own reader
.
The reader we purchased only came with one tag, perhaps that is why the they have been on clearance. Hooked up to an FTDI USB to serial cable, it would repeatedly send out the tag’s number whenever it was in range. We tried an HID-labeled card and a tag of the kind that can be found in books and DVD cases. Neither worked with the reader, but we’ll keep looking.
Thanks to [bluewraith] for the tip.

If you look at the data sheet parallax provides, they mention ” The Parallax RFID Reader Module works exclusively with the EM Microelectronics-Marin SA EM4100-familyof passive read-only transponder tags. ”Which, according to this data sheet :http://www.digchip.com/datasheets/parts/datasheet/147/EM4100.phpthe em4100 series is 125KHz.I do not know if any/all 125KHz chips will work or if the reader is looking for a specific sequence or ID before it sends out the tag it receives.I am really looking to make one of the RFID beer fridges they featured on SYSTM a while back.",

Reader [Tim Upthegrove] sent in a novel take on powering and monitoring AC outlets and devices called
SPRIME
, or Simple Powerline Remote Interactive Monitor and Enforcer. Compared to previous hacks, such as
120v switching
or
Quick cheap remote outlets
, that only turned an outlet on or off; SPRIME allows not only control over outlets via the internet, but also power usage of devices currently plugged in.
We really liked their idea of giving power companies
access to SPRIME
outlets to reduce power consumption during peak hours, but sadly we don’t see it being implemented in homes any time soon. Catch a video of SPRIME after the rift.
[Thanks Chris McClanahan and Jeff Starker for the project, and deyjavont for pointing out our silly mistakes]

"content": "@Jacob “giving power companies access”Although it looks good on paper, I’m pretty certain that this is not a good idea.The biggest power sinks in a normal household are the ac, the refrigerator, the stove/oven, and possibly the clothes washing machine/dryer. If the power to any of these gets cut for too long, too often, or at the wrong moment the results could be pretty inconvenient.Imagine if they cut power to your fridge for a little too long. Yummy.If they cut power to the dryer for 30 minutes when you’re washing work clothes and taking a shower, you end up late.An lastly, the air conditioner. The highest cooling load is also the hottest part of the day. Not sure about your ac unit, but mine works best if it turns on about 2-3 times an hour for 5-10 minutes each. When I turn it off manually the temp rises fairly quickly, then it has to run longer to get back to the target temp. In the meanwhile, I’m uncomfortable.Also, What happens when they manage to break the system, and your ac/fridge gets power cycled 20 times in a 2 minute period? Compressors don’t like rapid cycling. Do you really think they’ll even admit to screwing up? At least when they do it now, I’ve got a whole neighborhood with the same problem.Also, to those of you who might say I’m just being paranoid: If you are lucky enough to have a competent utility company, good for you. I am not so lucky, and neither is a large chunk of south Louisiana.I went 2 months without power after the last hurricane, and I’ve had 15 blown battery backups over the last 2 years.There’s no way I’m giving these idiots outlet-level control over anything.",

IT will not control your refrigerator or your air conditioner.Those things will start in buisness and commercial application before going into houses.”That is incorrect. They are starting with Residential, because the cost to most businesses for turning off power is too high. Most factories have deals with the power company where they are rebated for power outages.Most larger building pay for power at a flat rate based on peak usage. The reason for this is simple Factories and office building or ‘steady users’ They can pretty easilly calulate and plan for that demand. What they can’t plan for as easily is residential demand.As Eric noted Duke-Energy already offers a device that connects to your HVAC Compressor (the part that is outside, the inside fan continues to run) The power company can turn off your A/C for up to 20 minutes an hour during a peak usage time. This allows the power company to flatten out the power spike a little. As an insentive they offer your a small refund for any month in which they power cycle your HVAC.You will find that this will become mandatory for residential “Non Essential” uses in the future. They are already manufacturing Electric Dryers that can tie to the Smart Grid to be turned off during peak times as well.To my knowledge it isn’t mandatory anywhere yet. But the day will come.@eldorelMost compressors have protection against rapid cycling.If you are blowing UPS’s. You can request your power company connect a data recorder to your meter and they will monitor for voltage fluctuations for a period of time. Normally a week to a month. You can get a copy of the report, and they will work with you to solve the problem if one exists.The devastation caused by a hurricane can certainly cause enough damage that it can take months to restore power. First they need to rebuild the High Voltage lines, then they work out to the feeders and residential.Here in Indiana a tornado took out power poles around my home. We were without power for 4 days. That type of devastation takes time to fix.",

It looks like Toshiba has
a webcam-based multi-touch display on the way
. The video shows an iPod-esque photos album interface where the user stands in front of the display and manipulates it with both hands. The difference between this and some of the
other multi-touch
displays we’ve seen
is that there is no touching necessary (goodbye fingerprints!). The user’s image is superimposed on the screen in a way that reminds us of the original Playstation Eye. Obviously this is much more refined, making us wonder if it’s the better camera, better processing, or both.

GSoC Takes On XBMC On The Beagleboard
|

"gsoc",
"xbmc"
] |
Imagine a tiny little device that you velcro to the back of your TV that delivers all of the media found on your home network. We’ve been dreaming about that since we saw early working examples of
XBMC running on a Beagleboard
. We’ve heard little about it since then but now there’s cause for hope. XBMC optimization for the Beagleboard has been
approved as a Google Summer of Code project
. The fruits of these projects tend to take a year or so to ripen, but we don’t mind the wait.
[Topfs2] is the student coder on the project and will be posting
weekly updates
as well as idling in IRC so if you’re interested in lending a hand with testing or words of support you should drop him a line.

Ask any engineer what originally sparked their interest in technology, and almost universally the response will be a Hollywood film or TV robot —
Star Wars’
R2-D2, the B9 robot from
Lost in Space,
or
Short Circuit’s
Johnny 5
, to name a few. Engineers need a creative outlet too, and some pay homage to their inspirations by building elaborate reproductions. At this year’s
Maker Faire
, droid-builders had their own corner in the center hall, their work ranging from humble craft materials to ’bots surpassing their film counterparts in detail and workmanship.
Probably the most beloved film robot of all time would be
R2-D2
, and probably the best-known reproductions originate from the
R2-D2 Builders Club
, who’ve been profiled in
Make
and
Servo
magazines, among others. Every kid’s dreamed of building their own R2, perhaps from a wastepaper basket and scrap, but the club’s astromech droids are anything but kid stuff, with machined aluminum domes and intricate motor and sound systems. The club doesn’t sell robots — that would infringe on trademarks — but they do share techniques and component plans. The finished droids (are they ever
really
finished?) put in appearances at
fan
conventions and charity events.
Danger Will Robinson! Career inventor [Andrew Filo] has been engineering practical everyday items for three decades, but he
cuts loose by bringing his early inspirations to life
. His carefully-researched reproductions include an Apollo-era NASA spacesuit and a talking, walking…er, rolling…B9 robot.
Self-described recluse [ELS] is a builder and collector of film props and reproductions. Though he insists his Robby and B9 aren’t perfectly canon, you’d never know by looking; the detail and finish on these two was
amazing.
Robby is wearable, and periodically through the weekend he’d climb into the suit and
entertain a new generation
who otherwise might not be acquainted with this Hollywood classic.
[Matthew Ebisu] is obsessed with all things Pixar. As one of the younger makers exhibiting, [Matthew’s] materials may be simpler, but his enthusiasm more than fills the gap. He’s built — and launched — Carl Fredricksen’s house from
Up
in miniature form. It didn’t quite reach South America, but did net him a pen pal in Nevada. His Autopilot and Eve droids from
Wall-E
are more craft than tech, so his latest project, along with a gaggle of like-minded friends on his
D.I.Y. Pixar fan site
, is to develop a working Wall-E robot.
So readers — is there a favorite Hollywood ’bot to credit for your passion for this hacking madness? And have you built one yet? A
HAL-9000 in your kitchen
? Tell us about it in the comments, or if you have a build log posted online somewhere, drop us a link at
tips@hackaday.com

USB Morse Code Keyboard

"Peripherals Hacks"

"morse code"
] |
Looking for motivation to practice morse code [BenB] built this
morse code keyboard
. It uses USB and is recognized as a standard keyboard thanks to the V-USB stack running on the ATmega168. The project is rounded out with a clean look thanks to the chewing gum container that serves as an enclosure.
His design is simple enough that any morse key you have on hand can be used. You could even adapt that
glove coder you built a couple of years back
.

In this video from Maker Faire, [Jon Beck] of CLUE — the Columbia Laboratory for Unconventional Electronics — demonstrates the unexpected ease of
creating custom electroluminescent (EL) displays
using materials from DuPont and common t-shirt screen printing tools. Eagle-eyed reader [ithon] recognized the
Hack a Day logo
among the custom shapes, which escaped our notice at the time. Sorry, Jon! Very cool project, even if the setup is a bit steep. You’ll find links to materials at the project site.
If the interviewer seems especially sharp, that’s because it’s none other than [Jeri “
Circuit Girl
” Ellsworth], who
makes transistors from scratch
and designed the
C64 DTV
. We’re not worthy!

Unlocking The Crippled Potential Of An Unmanaged Switch

[Sprite_TM] outgrew the features of the cheap unmanaged TL-SG1005D switch he was using on his home network. Instead of buying a new and much more costly switch
he cracked the cheap one open
and found that the RTL8366SB chip inside possessed the ability to work harder but was crippled for sale as a low-end model. It wasn’t as easy as that
oscilloscope firmware upgrade
we saw a while back. He had to add an AVR ATmega88 to send I2C commands to the switch. Turns out that the I2C protocol wasn’t standard and after much head scratching he found some Linux drivers for the chipset that gave him enough info to send the configuration commands he needed. Now he’s go the managed switch he needed for his VLAN for the cost of a microcontroller and some wire.

PLCC Replaces Game Boy Cartridge ROM

[Gerry] sent us pictures and a few details on replacing the Game Boy cartridge chip with a flash chip. For the prototype he used a PLCC and a little
wire porn
to interface a flash chip with the cartridge’s PCB while still having access to it for programming. In retrospect he plans to use a 32-pin ZIF socket on the next version to make things easier. It does work and he’s had some success loading his own code and getting it to run. There are
other cartridge hacks
that let you load code onto a cartridge but if you have the knowhow and the parts this makes for a fun weekend project. We’ve posted the rest of the photos that [Gerry] sent us after the break.
Update:
Gerry is working on a video and a pinout. We’ll post info once we get a hold of it.

However, the reason I mentioned using a ZIF socket as opposed to the PLCC; was due to the amount of wear and tear that was occurring with the PLCC socket. PLCC sockets were usually used for BIOS chips and are only meant for periodic changes. Now in contrast, the number of times a user will be re-programming their flash chip when trying different games is much higher. This is the same reason why Universal Programmers are equipped with ZIF sockets.Or shall I say “Zero Insertion Force” sockets.To me it just makes the chip change and re-programming much faster overall.But Hey! That’s just me. :)",

Mass Storage Business Card

Just snap off the corners and this
business card can be used as a mass storage device
. Well sort of. The tab left over has four traces on the back to make it USB compatible. The PIC 24FJ64GB002 microcontroller on the card registers as a storage device and launches [Ramiro’s] resume and a cover letter loaded as an HTML file. He’s made it as useful as possible by including access to the SPI and I2C bus connections but he’s also included some firmware to act as a data logger or an oscilloscope. At about 5 euros a piece you won’t be distributing these willy-nilly but it’s not too much more than
handing out breakout boards
with your name all over them.

Aircraft Carrier Is Moving Target For Autonomous Quadcopter

[Karl-Engelbert Wenzel] developed
a UAV capable of taking off and landing on a moving platform
autonomously. The platform operates aircraft-carrier-style by driving around the room in circles. The quadcopter tracks a grid of IR LEDs at the front of the landing deck by using the IR camera from a Wii remote. The best part is that the flight controls and processing are all done by the copter’s onboard ATmega644 processor, not requiring a connection to a PC. The landings are quite accurate, achieving a maximum error of less than 40 centimeters. In the video after the break you can see the first landing is slightly off the mark but the next two are dead on target.
So build yourself a mobile platform and pair it up with
your newly finished quadcopter
to replicate this delightful hack.

At first, watching this video of
MABEL, a bipedal robot for studying dynamic gaits
, we didn’t know if we should be scared or feel sad. By the end, we know that sadness prevailed. Poor MABEL, forced into a grueling routine, is not even allowed to rest when her leg breaks.
To be serious though, MABEL is quite impressive. Instead of using a direct drive on the legs, motors are attached to springs that act like tendons. This helps compensate for variances in the walking surface, hopefully allowing for smoother transitions between gaits as well. As you can see, MABEL handles the height differences quite well, albeit a bit slowly. It is worth noting that there are no visual sensors on MABEL and everything is done through feedback from her gait.

Just when you think it couldn’t possibly get any bigger and crazier, they manage to outdo themselves
again.
The
Bay Area Maker Faire
wrapped up Sunday evening, but we have so many story leads that we’ll probably be busy until next year’s event. In the meantime, here’s just a tiny, random sampling of the countless delights that greeted visitors this past weekend.
Setup day was the only time we could get a clear shot of the
Hermes space shuttle
, [Morris Jarvis’] entry in the suborbital tourist space race.
Early Saturday morning, the line stretches to infinity and beyond.
At the other side of the fairgrounds, scads of locals took advantage of the free bike valet service and scored a $5 admission discount to boot. And this view shows only about
half
of the bikes present! We only spotted one
recumbent
parked out here, but quite a few inside as maker exhibits.
So much walking! This kid had the right idea, scooting around in luxury.
It’s not a Bay Area party until the original
Doggie Diner heads
show up!
Robots
were
everywhere
this year. Of course the
R2 Builders Club
was on hand…
…but there were no Wookiees present to play
chess
against this robotic arm.
A row of
Anybots
, all ready to take up their
overlord
duties.
Our favorite giraffe joined the rave, replete with his
new animatronic head
.
The
Mondo Spider
, like its smaller biological inspiration, manages to be simultaneously fascinating and potentially deadly. It is, however, anything but silent.
Back outside, this
MIDI
-controlled
pneumatic
dinosaur
alternately entertained and terrified children. We were hoping to witness a one-on-one battle against…
…Saphira, the
fire-breathing dragon
!
Rar!
Nearby, [Haley Duke’s]
Swamp Kirin
puppet loomed over fairgoers. Kirin, we just discovered, appear to be mortal enemies of efficient JPEG compression.
[Todd Williams’]
Land Shark
is an animated EL wire-framed skeleton atop a large
radio controlled car
chassis — a great effect in the dark!
We seem to be on a bitey creature kick. Here, have a
Velociraptor
head popped out of a commercial ABS extrusion 3D printer.
We
posted about the DIYLILCNC mill
late last year. What struck us when finally seeing it in person is how it’s anything
but
li’l. This thing bullies
RepRaps
and takes their lunch money!
They were even making something in the Maker Shed store. What exactly? We’ll give you a hint: it’s printed with green ink on the back. Man, they got us
good.
Went in needing just one Parallax
RFID
reader, and somehow couldn’t leave before spending the equivalent GNP of Guam.
This is here
just for blog cred
.
Our hats are off —
again
— to SparkFun Electronics. These guys could’ve easily brought enough merchandise to bankroll their retirement from this one show. Instead, they taught kids how to solder. How cool is that?
FPGA pr0n from
Art Magnitude’s ORB v.2
, a
persistence-of-vision globe
on a grand scale.
There was always a line waiting to play with Tangile interaction’s
digital graffiti wall
.
This way to the egress!
If we’ve overlooked or glossed over your favorite subject or display, it may be that we’re expecting to cover it in more detail in the future. Keep your eyes peeled for more wild stuff here!

I think she even made it to BoingBoing. Crazy.When it comes down to it, hacking and making is about the community.

Maple R3 Now Shipping

[

"arm",

"r3"
] |
Leaf Labs is now shipping
the Maple R3 boards
. [Phil Burgess]
gave the platform a look
just before launch last fall and the high-powered prototyping board is now even better. New features come in both hardware and software varieties. The bootloader can now be upgraded without additional programming hardware, there’s hardware SPI and I2C interfaces, and a newly-polished IDE for Linux and Windows. At $50 it’s a good way to get access to the power of the ARM Cortex M3 processor at the center of the board. We’ve seen several projects that use
the mbed
, which is in the same class as the Maple, but we’re waiting to see what you’ve accomplished with this little devil.

DB9 Form Factor USB-RS232 Replacement
|
Mike Szczys
|
[
"Parts"
] |
[
"db9",
"ftdi",
"rs232",
"usb"
] |
If you’re attached to that favorite DB-9 interfaced device you should look into this part. FTDI is selling a
USB-RS232 adapter as a replacement for DB-9 connectors
. They come with USB male or female connections depending on the application and have the same serial footprint and pinout to which you’re accustomed. Using converter cables is just fine but this simplicity requires a few minutes of desoldering, rather than redesigning, etching, and populating a board in order to give that older design built-in USB connectivity.
[Thanks Juan]

SSOP package kept me on the distance so far (I can’t be bothered to go through board design and manufacturing ordeal for my one-off projects). I’d rather have some fairly simple (from users’ POV) D+,D- -> Rx,Tx; 5V supplied; 8 pin IC; generic blackbox. That would at last be a MAX232 killer. Until something like that comes around, it will still be much simpler to ignore USB for all small projects and have one USB-to-serial cable handy.",

Instead of building a $500 iPad into a cabinet [Gojimi] used the old hardware he had lying around to building this
kitchen computer
. He did buy a few items such as a used touchscreen and a bar code scanner but the 2 GHz computer was just collecting dust. It’s running Windows XP, talks to you like
HAL
or
KITT
, and scans the bar codes on food as you add it to the pantry or using it for meals. The lengthy video after the break covers all of the features, such as Weight Watcher’s calculations, food information, recipe book, unit converter, weather forecast, browser, and digital picture frame. It seems to have more features than
the iPhone kitchen lookalike
but it also looks dauntingly complicated. But we still want one.

One-armed Coding Using A Half-qwerty Hack
|
Mike Szczys
|
[
"Peripherals Hacks"
] |
[
"diabled",
"half-qwerty",
"one hand"
] |
[Matthew Daughtrey] is going to have one of his paws out of service for a while following some hand surgery. Making a living as a coder seems a bit harder with one hand but he was able to find some solutions online only to balk at price tags reaching $600. He came up with a way have similar functionality on a standard keyboard
with creative key mapping and a few auxiliary buttons
.
The product he’s trying to mimic is
the half-qwerty keyboard produced by Matias Corporation
. It sounds crazy, but you can easily use your right hand to type all of the letters the left hand normally would just by mirroring the key locations. That big gray thing you store in your mellon and
frequency put at risk
handles this automatically. You should
give the demo a try
. We found that we’re quite good at it and only get confused when switching between the two halves of the keyboard.
But we digress. [Matthew] wrote a script that will mirror all the key mappings when he holds down the Windows key. He then hacked a second keyboard to extend momentary push sensors as seen above. He plans to use them with a partially mobile thumb after the surgery, or to build a foot pedal (we say build the pedal). An elegant hack that is a pittance compared to the official hardware.

The more you invest up front the bigger the production run you can afford and the lower the retail unit price. To get a keyboard down below $100 you must manufacture a whole bunch of them; you have to borrow a whole bunch of money up front.Very often, the more innovative your product the more uncertain the market and the more likely you are to share the pain with early adopters and people who really need your gizmo rather than bet the farm to finance a huge production run.Example: A manufactured bluetooth keyboard costs about the same as one of the bluetooth modules inside it.So maybe think harder about who sucks and who doesn’t",

"content": "I agree with john_3000 on products that are novel or new. I work for a hardware manufacturer, so I see this every day. There’s a schedule for recouping the engineering time involved, and that schedule is based on number sold. Smaller number sold, higher price required to recoup. The fear of impending obsolescence also factors in. You can’t look long-term if the product is going to be obsolete soon, so a highER price is a must.There another aspect in this case with Section 508, though. The door opens to charging more for items that may be purchased through Section 508 as opposed to through other means.It’s similar to some medical providers charge way more than is necessary for the procedure, because they *know* they can bill insurance for it.A procedure may cost $500 for the uninsured, with significant discounts for paying cash or up-front/in-full, while I see the same procedure billed to insurance for twice or more. Likely the procedure itself costs somewhere in-between, as the discounted price may provide a higher percentage of actual payments from the uninsured, compared to the guaranteed payment from insurance.Market share is definitely dependent on price. But overall cost to the company also depends on marketshare. Larger marketshare results in higher rate of returns and more users to support. So lower price and higher marketshare can often cause more supports costs in the end compared to the higher price and smaller marketshare which is easier to support, and support well given the revenue.Would Matias sell more half-qwerty keyboards if they were cheaper? I think so. I’d buy one.But it seems they feel they have a good cash cow there – sell a few for high price, and it’s a high-profit scenario. It’s not like they have thousands of geeks bombarding them with requests or questions. So as long as there isn’t a cap on Section 508 device prices, they’re all going to be pricey and exclusive.It sucks worse that they squash all competitive products with their lawyers though… and maybe that’s the core rub.I’d love it if this wasn’t the case, but businesses are businesses because they’re there to make money – otherwise they’d be charities.@Eric: I’ve used Dragon in the past. The difficulty is the error-rate and the need for a semi-controlled environment. I kept getting “shed” and “flock” in my documents because I get frustrated.I’m sure with enough time I could get it going. But the same could be said about typing on a half keyboard, and it doesn’t matter if I’m in a concert environment or not for that to work reliably.It’s like those damn voice-recognition phone systems. If you’re not in a silent environment (umm.. I’m calling from a noisy store because my credit card got denied here!) they get all confused. At least the last place I called gave me the option to use touchtone-only navigation!",

Sound Card Driven Servo Motor

[Darrell] is
using a sound card to drive this servo
motor. The motor draws power from a cellphone battery with the control signal coming from one of the audio channels. It’s not too surprising that this works since the motor just needs
a PWM signal
to operate and that’s what is used to create the different frequencies of sound on electronic speakers. We’re not sure what [Darrell’s] got planned for this system but he mentions that two servos can be used, one on each audio channel. If you’re not using your sound card this would be a way to stop using the Arduino for that
mail checker
and just use a little flag attached to a servo. When mail comes in the appropriately engineered sound raises the flag.

Are you hardcore enough to build your own 32-bit ARM powered gaming console AND use point-to-point soldering to accomplish this? [Craig Bishop] did just that when building his
GameSphere console project
. First thing’s first, click through the jump and watch the game play video. He wrote that game in the C language in less than a day which in itself is quite remarkable. On the hardware side of things he’s got an interesting mix; an Ateml AT91R40008 chip drives this system with PIC 18F4682 for VGA signal generation and a PIC 18F2685 to interface with the N64 controller. We like what he’s done so far and would love to see this end up in its own
game cabinet

Mr. Stabby was once a broken down bum
, sitting on the curb, waiting for an eternity in the city dump. Luckily, someone found him and brought him to the NYC Resistor hacker group. They promptly performed some modifications and brought him back to life.
He’s now a happy go lucky stab-bot with a twinkle in his eye and a skip in his step. His repitoir includes gouging, slashing, and of course stabbing. He can be controlled via a cell phone and has a nifty voice interface.
The video above is from when Mr. Stabby was runner up at the tech crunch hackday.

Since the
previously-posted stills
can’t quite convey the chaos of last weekend’s
Maker Faire
, here’s some video from the event to help get you through
hump day
. It’s like three liters of Jolt Cola in a two liter bottle.
One thing even video can’t adequately capture is our
gratitude
toward our readers at the show who took time to express their appreciation for the blog. You guys and gals rock our world. Thank you!

Head Mounted Camera Tracks With Your Eyes

"tracking"

The
EyeSeeCam
is a rig that attaches to your noggin and points a camera wherever your gaze falls. There’s actually four cameras involved here, one to track each eye via a reflecting piece of acrylic, one as
your third eye
, and finally the tracking camera above that. There are some legitimate medical uses for this type of technology, but we enjoyed seeing some of the videos that [Johannes Vockeroth] put together showing everyday activities. We’ve embedded several clips after the break including an example of reading a book while wearing the apparatus. The third eye camera provides the wide shot with close-ups of the wearer’s visual focus.

(Also I didn’t use the mirrors and had to look at the eyes at extreme angles to not obstruct the view. Barely precise enough to select something on a 3×3-Grid).What I’d like to see: instead of USB webcams use android phone(s). More freedom.

Have you ever tried to smoothly pan your eyes from as far right as you can look to as far left as you can look (of course without turning your head)? Your eye moves in jerky, non-smooth, motions. Almost stepping across your field of vision.You may be right, but I think it is probably closer to how your eye moves than you might think.The thing I would like, however, is the ability to turn on and off the maginification, or zoom at will.

Keeping your eyes focused on your target would probably be detrimental to your play, it’d effectively be tunnel vision.

Cool Yourself With A CPU Cooler And Beer Fridge

We have arrived once more at the time of year when penniless (or bored) hackers try to figure out how to keep the place cool without buying an air conditioner. [Paul Stacey] sent us his solution of pairing up a
CPU cooler kit with a beer fridge
. The CPU heat sink is cut out of a liquid cooling kit and discarded. In its place a loop of plastic tubing enters the freezer of the beer fridge where it exchanges salt water from a reservoir. The cold liquid circulates through the radiator of the fan kit and gives up it’s cool goodness through the fan unit seen above. This method puts a cold-air fan right in front of you with a digital temp and fan speed readout on the LCD.
Our biggest concern here is that this might heat up the beer in the fridge. Still, it’s more automatic than using
a homebrew swamp cooler
. Then again, we’ve always had a soft spot in our hearts for
our favorite gravity fed cooling method
. Anyway, check out [Paul’s] build methods after the break where he makes it look quick and easy.

Refrigerators and freezers work because they remove heat from a relatively small area (inside) and dissipate it into a larger one (the room). This project is like leaving the fridge door open all the time.Putting the fridge outside would solve at least that problem, but then you’ve just made a very inefficient window air conditioner.If you replace the CPU cooler with something more substantial, say a box fan with an old fridge radiator mounted to the front, the cooling potential increases. (However the effective life would decrease and you would have to top the ice off more frequently.)",

This
installation by artist [Nils Goudagnin]
is a recreation of the hoverboard from
Back to the Future II
. We would like to see inside that plinth. We’ve seen levitating magnets before, but this is particularly stable. He says he is using lasers and a control system of some kind to stabilize it. Just to guess, we’d say that the lasers determine the distance of the board and an array of electromagnets below is adjusted to keep it level. Then again, we might be over thinking this. Even though it can’t be ridden, we’d love to have one around the office just to look at.

This technique requires very accurate sub-nanosecond timing circuitry.Multiple frequency phase-shift – this measures the phase shift of multiple frequencies on reflection then solves some simultaneous equations to give a final measure.Interferometry – the most accurate and most useful technique for measuring changes in distance rather than absolute distances.from:http://en.wikipedia.org/wiki/Laser_rangefinder",

The electromagnets are probably strong enough to suspend the hoverboard as much as over a foot away, but you quickly run into stability problems with that.The difficulty with making it a usable hoverboard similarly rises from stability problems. Yes, like magnetic poles repel, but unlike poles still attract, so absent other forces, a magnet suspended above another will simply “do a barrel roll” and stick upside-down. This would be undesirable with a rider, and the reason the board is stable in the exhibit, I suspect, has more to do with the pillar it levitates over than the board itself. In short, to make something like this work, you would have to have a set of vehicles underneath the ground suspending the board above them: an engineering feat which gives logistical nightmares logistical nightmares, and the riders couldn’t get close to each other or the boards would start interfering, causing the balance issues to arise again.Also, it’s “half-pipe.” A half-pike is called a stick.",

[Jeri Ellsworth] stopped by Pearl Biotech’s booth at Maker Faire and took a look at their
open source DNA sequencing work
. It is by no means a grab-and-go solution for anyone, but from what we’ve seen in the video they’re breaking down those laboratory walls and letting us in to dabble at this work (assuming you’ve got a few hundred bucks to burn). There is a community for info and help that you can check out at
BioCurious
, and
Pearl Biotech
has
gel box kits
available (or
the details
if you care to source parts yourself), traditionally an extremely expensive part of the process. You’ll still need a centrifuge and a heating/cooling device to separate the strands but as you can see in the video, these can be hacked together rather easily.
We’re glad that [Jeri] shot and posted this clip. She does a great job of explaining projects, whether it’s someone else’s like this or her own, like the
transistor fabrication method
.
[Thanks Shazzner]

You then know what length that particular stretch of DNA is (and this can vary in different species or individuals for example).Sequencing is ‘reading’ the actual A C G T sequence of a stretch of DNA.Lastly, when DNA is heated and cooled (to about 72degC) it does not “heal itself” as the guy said.

Simple demonstrations but nothing more. For anything relevant you need a real lab with UV decontamination, reactants, sterile bench etc. No fucking way to do this at home without serious investments. And if one puts in money, the SDS PAGE will not be the limiting factor, even with off the shelf devices.",

I work in a genetics lab, and I can vouch for the power of my design if not its relative safety. :P Google “Dremelfuge” for details.As to the safety of the Pearl Biotech Gelbox and their approach, it’s not as dangerous as some here are suggesting. They designed the box to use the “Sybr-safe” dye rather than a more dangerous one such as Ethydium Bromide. Also, if you’re too poor to buy Sybr-Safe, you can use Methylene blue from an aquarium supply store if you have enough DNA.Finally, some forms of PCR can be used to determine the sequence of DNA at a particular one-to-three base-pair site. If a particular mutation has taken place, for example, a well-tuned PCR reaction will pass/fail depending on the sequence.Great to see so much interest in DIYbio on this comments list! I’m planning to make affordable, DIYable science my career in the near future, and I know the Pearl Biotech guys are doing a great job pushing for this already!",

2010 Sees New Lock Impressioning Speed Record

[Jos Weyers] tipping us off about this
lock impressioning video
. It shows his final round of the lock impressioning championship at this year’s SSDev conference. Even though he shaved about fifteen seconds off of his 87-second single-lock
record from last year
he came in third overall because the competition averages times over several rounds.
This method of opening locks uses a file to create the correct teeth after examination of tiny marks on a key blank from trying to open the lock. We’ve seen
foil impressioning
as well as
electronic impressioning
, but
video of the competitions
makes this our favorite method.

Quadcopter Acrobatics Like Nothing We’ve Seen
|

"acrobatics",
"quadcopter"
] |
The University of Pennsylvania has churned out some
impressive moves with a quadcopter
. Perching on a vertical landing pad with some help from Velcro is impressive, but single and double flips combined with navigating through tight spaces at an angle makes this just amazing. We expect to see it in the next Bond film if it doesn’t show up in one of this summer’s action flicks. Kind of makes
previously awesome quadcopters
look a bit pedestrian. Video after the break.

Russian Roulette… For EEPROM

There’s a loaded gun but its got only one bullet. Spin the cylinder, point at head, and pull the trigger. The game’s not over until the bullet is used and a player is done. This game’s got a twist though, the cylinder has at least one million chambers.
The
Flash_Destroyer is testing the limits of EEPROM rewrites
. It fills that little eight-pin chip with data, then verifies what has written. When it finds and error the game is over. The chip is rated for one million rewrites but while we were writing this it was already well over two and quarter million. We usually prefer to be creators and not destroyers with our hacks but there’s something delightful about running this chip into the ground. See the startup of this device after the break and click through the link above to see a streaming feed of the progress.

With wear leveling as part of the standard MO for thumbdrives and flash chips in general… That’s *EVERY* cell that should be able to be written to at least 500,000 times before you see the first one fail. (Older compact flash cards didn’t have wear leveling…)Aside from defective chips, Flash will effectively last forever in normal use.

Embedding An Accelerometer And XBee In A Guitar

[JP Carrascal] hacked his guitar by
adding motion control while removing the need for wires
. He’s using a dual-Arduino system with an Mini Pro inside the guitar and a Duemilanova for the receiver connected to a computer. Wireless is provided by the XBee module seen above and a gutted Wii remote accelerometer is in there for motion sensing. Check out the artfully blurry demonstration of the motion effects after the break.
While he added some potentiometer-based controls there is also an automatic power-down feature. [JP] replaced the mono pickup with a stereo one and used the extra conductor as a switch to activate the additional electronics. We wonder if he also
winds his own pickups
or
builds his own effects pedals
.

Bluetooth can reach speeds of 24Mbps, which is enough to do extremely high quality audio, or even video. Then again, Wi-Fi 802.11n can reach a maximum theoretical bandwidth of 600Mbps. All of the numbers are the theoretical maximum (except maybe the zigbee), so you can probably expect half or less actual throughput.So in summary, I love the idea (have been wanting to do this for a while), but for concert-quality sound, other wireless options would have to be explored.On a more random guitar note, anybody think it would be possible/plausible to design a pickup system that would be able to analyze every string simultaneously and convert the note(s) being played to a MIDI output?",

Adding SCART To A Cheap CRT Television

[133MHz]
cracked open a cheap tube television to add a SCART connector
. He knew he had a chance at success when he discovered all of the knock-outs on the back of the connector panel because one of them was exactly the right size for the connector. But it wasn’t quite as easy as soldering in one component. He ended up injecting his own RGB data from the SCART connector directly into the onscreen display, making an end run around the missing feature. [133MHz] removed some resistors in the circuit and used the empty lead holes to patch in his own circuit, feeding the RGB data from the SCART connector to the OSD chip in the format it needed.
This one takes you way down the rabbit hole. We’re glad he provided so much background about the hack but it’s going to take us a little while to fully wrap our heads around how he figured it out.
[Thanks Victor]

The benefits of SCART are nice enough, but the physical connector design is a right pain.That said, I’ve never seen a SCART cable included with a games console in the UK; they usually come with a composite lead and a cheap composite-to-SCART adaptor. Most people I know stick with the stock cables rather than shelling out for the more expensive RGB ones.",

After repairing both xbox1’s and 360’s, there is ABSOLUTELY NO REASON that microsoft couldn’t have added ports for everything – there’s plenty enough space on both. PS1 and PS2 may have been a little trickier, though I managed to add s-video and stereo audio to my PS2 without a hitch. Haven’t had the opportunity to screw with a PS3 or a WII yet……Don’t mean to hijack the comments, I started with a response to SCART in the US… Kinda snowballed from there.

RGB is also component video, technically, but it’s hardly ever referred to by that adjective (at least in the U.S.).Fun fact: The Luma signal in YPrPb/S-Video is very nearly identical to the NTSC (aka RS-170:http://en.wikipedia.org/wiki/RS-170) signals that were used before the advent of color TV transmission.@lurker: as can be seen on that map, Japan is/was NTSC (no idea what they’ve switched to as far as digital).",

Prison Tattoo Machine Made From PlayStation

Prison inmates have a history of being gruesomely resourceful hackers. The toothbrush shiv comes immediately to mind. One such inmate in the UK wanted to offer tattoos to his fellow convicts so he came up with
a tattoo gun using a PlayStation
for parts. The crude setup involves a sharpened ballpoint pen and the use one of the motors from the optical drive to move it up and down. The inmate didn’t document his work for us but there are
other examples of this method available
. Even with modern hardware, ink seems a little 20th century when compared to
laser tats

I do agree with you that NO prison should have entertainment, since it promotes crime amongst the youth.Although I do wonder why they do not jam cell phone signals in prison, isn’t very hard to do. Hell they could even set up their own cell transceiver, jam all the others and have every call from the tower routed through some sort of FBI listening post. Just put it into the employment contract at the prison, put up a few signs about monitoring communications and everyone is happy. You’ll also break up a bunch of drug rings and cells of organized crime.Still hilariously ironic to see a 200-lb, heavily muscled man with about 50% of his body covered in prison tattoos go through an MRI machine.",

Maybe $15K for an elaborate
balancing telepresence robot
is a bit out of one’s league. In that case, another Bay Area Maker Faire exhibitor — Wild Planet — has you covered. Faire attendees got a hands-on sneak preview of the upcoming
Spy Video TRAKR
, a video-transmitting radio-controlled toy that’s programmable and extensively hackable.
The TRAKR has an impressive pedigree. It’s a collaborative effort between three successful and creative technology companies: Wild Planet, makers of the
Spy Gear
toy line; MOTO Development Group, designers of the
Flip Video
camera; and Making Things, software designers for the
Make Controller
.
So just how hackable are we talking? The Spy Video TRAKR is intended right out of the box to use downloadable apps, and allows development of new programs in C. The controller and vehicle each contain their own ARM9 processor, and the ’bot features 8 megs of RAM, an SD card slot and USB client and
host
(yes,
host
) ports. And that’s all with the cover still on. Pop the lid, and you’ll find links to online schematics and neatly-labeled breakout headers for deeper exploration.
The Spy Video TRAKR is expected to ship in October with a target price of $139 or less. Additional photos after the break.

It is the opposite end of the spectrum from products like games console who take extra steps to try to stop nerdickery, and demonstrates that giving your nerd-base a big hug can be a benefit instead of a curse.Kudos to Wild Planet, and may more companies follow your lead.",

It’s in the works on our end here and we’re planning to make it backwards compatible.RE: Controlling via PC/USB: There is USB connectivity in the remote. The main purpose of this USB is to allow field upgrading of the firmware and we’re looking in to see what else is possible with this USB port. If/when we make it work; we’ll gladly share the details with the community.RE: Sharing documents: Yes, the source code will be available and we plan to put a lot of info on SpyTRAKR.com as soon as the site is ready for launch.Just 3 more months to go!Thanks for your patience. -Kim",

It’s something we’ve wanted to do, and we won’t rule it out forever, but it puts the final product out of reach for a lot of people (from a financial standpoint). Rechargeable batteries are imperfect, but they seem to be the best compromise for now.2.\tThe cargo rack is pretty sturdy, and could easily be reinforced.3.\tAt this point, we see the USB host in the TRAKR as having the most utility. However, we’re excited to see what you all do with the TRAKR. If it looks like there are a lot of interesting applications for a remote-side USB host, then we’ll definitely look into that as well.Hope this helps! Thanks. -Kim",

Here’s a little more information that might help such a person:– There’s an ARM-9 processor onboard, which can be controlled by custom apps.– There’s an accessible USB host port, so you could come in through there.– If the case were somehow cracked open(not that we would EVER encourage someone to do that), you have access to several I/O ports.– So, in theory, you could use an Arduino board and plug directly into the I/O ports and control things that way, or you could use the USB host and a custom app and work something that way.– We have not been focused on creating AI and personalities, but this should be something doable with the apps once the programming support is online.– I don’t know about cross compiling. That’s something that we’re not likely to support, but there’s nothing in the system to prevent someone from creating that functionality. If you figure this out, we’d be happy to help you share with other users.Hope this helps! -Robin",

Sun Tracking Solar Panel

As we all know, a solar panel must be exposed to the most amount of sunlight possible to reach full efficiency. A solid mount limits the amount of time that the panel is fully exposed to direct sunlight. The solution is to
build a pivoting mount that automates the process of aiming at the sun
.
[bwitmer] takes us through the process of building one out of some wood and old bicycle rims. He bought a
pre made tracking unit
to control his actuator, but we think
many of you
here could
rig something up
on your own.

"content": "Coming at this from a purely theoretical standpoint:Assumptions:-Only inclination tracking, effect of azimuthal angle assumed negligible-Approximately constant radiative flux regardless of sun position (obviously not true for close to dusk/dawn, but otherwise fair)-Constant panel efficiency regardless of radiative flux-Collected solar energy is proportional to the dot product between the radiative flux vector and the normal vector of the plane of the panelk is a constant of proportionality including things like panel efficiency, R is the radiative flux field, and A is vector for the plane of the panel, P is instantaneous power output of the panel, E is the collected energy for one day,T is the length of a day, and theta is the angle of incidence of the xuns rays on the panel (aka the angle between A and R)First, calculating the instantaneous power P:P = R·(kA) = kRA cos(theta)Next, calculating the total collected energy, E:For a perfectly tracking panel where the angle of incidence is always zero and intercepts the largest amount of light:theta = 0, so P = kRAand E1 = PT, thus E = kRATFor a stationary panel pointed radially away from the earth:P = kRA cos(theta), but theta changes at a constant rate from pi/2 to 0 back to pi/2 from t=0 to t=T. Rather than calulate theta explicitly in terms of t, we can simplify by saying that theta = Ct for T/2 to T, where C=pi/T(using pipe, |, as the integral symbol)E = |P(t) dt (for t=0 to T)or E = (1/C)|P(theta) dthetaSo E = kRA/C |cos(theta) dtheta (for theta = pi/2 to pi)so E2 = 2kRAT/piThe ratio of energy collected, E1/E2 is pi/2, approximately 57.1% more energy collected by the tracking panel before losses to powering the tracking. This is independent of panel size, amount of sun, length of day, efficiency etc.If the panel is mounted so the axis of rotation is coincident with a north-south line and passes through the mass center of the panel, and the panel is mounted on good bearings, the required torque to move the panel should be relatively small.Work = Torque(angular displacement)Torque = I(alpha)+rolling frictionSome quick back of the envelope calcs yield W = 100*{[1500(L^4)D^2]/(t^2) + 1.8(pi)u(g)(L^3)}(u is the rolling resistance of the bearings, t is the permitted rotating time, D the size of one angular increment, and L the side length.)for the required work to rotate the assembly for the whole day. This assumes that the mass of the assembly will be proportional to its area, the required axle diameter is proportional to the length of one side of the panel, the panel is square, a surface are density for the panel of 90kg/sq m, and a aspect ratio of 0.02 for the axle diameter to side length.Say we rotate our panel in 100 increments throughout the whole day (180 degree rotation) and wish to only pulse our motor for 5 seconds to achieve the desired rotation increment, after which we brake. We’ll use crappy bearings with u=0.004, and a panel 1m on a side. W = 300 J, an average power consumption for 10 hours of 0.008 watts.Assuming lets say 10 hours of sun at STC and a 12% eff panel the tracking one will produce 43.6 more watts of energy, more than paying off the 0.008 consumed by tracking.",

BAMF2010: QB Goes To Meetings, Shoots Lasers From Eyes

No, it’s not an extra from
Wall-E.
“QB” is the latest telepresence robot from Silicon Valley firm
Anybots
. QB combines two-way videoconferencing with a
Segway
-style self-balancing platform. The idea is to provide mobility and more natural interaction than desktop-tethered conferencing can provide.
The 35 pound robot’s battery runs for six to eight hours, and the telescoping head allows the eye level to be adjusted to match the user’s natural viewpoint. What looks like
stereo
vision is actually a single camera on the left eye and a steerable
laser pointer
on the right.
Shipping this October for $15,000, QB will appeal mostly to businesses with specific
telepresence
needs. This is half the price of their prior
QA
model — and in time the technology may reach the mass-market level. Until then, we’ll just have to amuse ourselves by remotely attending meetings with our ankle-nipping
Rovio
robots.

Okay, we lied, we totally want one of these too. The
CMT 380X Blackbird
is one
wicked
hybrid car!
Looking like it just rolled off the set of the next
Batman
film, the Blackbird is the brainchild of Electronic Arts Chief Creative Director [Richard Hilleman]. Starting from a kit car base — the Factory Five Racing GTM chassis — [Hilleman] created a unique 230 horsepower drive train combining a 30 kilowatt diesel
turbine
and 24 KWh
lithium polymer
battery pack.
As a purely plug-in
electric car
, the Blackbird has a range of 85 miles. In
hybrid
mode, range is extended to 500 miles. The car can accelerate from 0 to 60 in about 7 seconds. Come decelerating, the car makes use of regenerative braking.
It’s strictly a one-off for the time being, but several companies have approached [Hilleman] about possibly commercializing the design. A couple more choice pics follow the break…

Some of my favorites (depending on pleasure, utility, efficiency or various combinations, have been an Austin Healy 3000 (pleasure), a Geo Metro Xfi I could squeeze 62.5 mpg out of and travel all over Southern California in averaging 52 mpg (a total cost of ownership and operating cost of $0.125 per mile) as well as hauling all sorts of hardware like 8ft x 42 inch end pieces of Home Depot type racking I installed in my garage (staying within the 3ft overhang limits). An 83 Diesel C20 Suburban hauled aircraft display trailers with great in town fuel mileage and enough weight and brakes to control the heavier trailers. A 72 LUV pickup with a 350/350 got up to 25 mpg, tons of fun and useful load capacity.I would use Richard’s car as a fun to drive commuter with above average fuel efficiency from regenerative braking in town and streamlined efficiency on the longer trips it can make. The only additions might be a solar panel roof to a bit to either battery charging on the long trips, or to power fans or other cooling devices (Peltier Effect) if some brief extra (but relatively inefficient) cooling is desired such as pre-trip cooling beyond just circulating fans. There may be some thermo-electric generating possible from higher differential temperatures with the turbine waste heat, but the cost benefit may be too low for anything other than demonstration purposes.",

"content": "A note from the creator.A couple of the numbers in the story are wrong, and you are getting a couple of different stories combined.First, Capstone helped (as did AC Propulsion), but their funding help was VERY limited. I paid almost all of the bills myself. The CMT380 that Capstone described would be a production car, with a multi-speed transmission, and an updated electric drive system with liquid cooling. I built a single gear car, as it is focused on my Highway Cruise. That is the Top Speed difference.Second, the weight is 3154, It is about 600lbs heavier than the stock GTM. There is 200 lbs of battery protection under the cabin, that will become ruberized Kevlar, and a lot of aluminum that will eventually be CF. We should get about 250lbs back.The Fuel tank is 10.4 Gallons.Third, this car is built and geared for Long Distance Cruise, not 0-60. The 7 second time is a real number, driven on normal streets with a full tank of gas and a passenger. I haven’t pushed the car at all (how about we don’t brake it during the test cycle. It is probably better, but I haven’t pushed it. The Engineering math says it should be in the 6’s. You are absolutely right that a Tesla is quicker 0-60, but I will beat them to LA, and that was the point. I have a 550 Spyder Electric Car that is the match for the Tesla’s 0-60 and I built it in 1995. (looks better too). By the way, this is better than any street Ferrari made in the 70’s, 80’s and most of the 90’s.Fourth. This is a personal project, with a lot of stuff that no one had done before. It rolled out of the Garage in mid Feb, and has done more than 700 miles with NO FAILURES. I’m pretty proud of that engineering and I have never had an ICE car I built accomplish that particular trick, with a lot less new stuff going on.Finally, the Seats are more comfortable than you think. Steve Tillett built the seats that a number of the 24LM cars used this weekend. I have done more than a 100 miles (2+ hours) in the saddle and it hurt more to get in and out than to ride in it. It has hybrid airbag/coilover suspension. It rides surprisingly well.Thanks for your support. I was trying to show that a car could be built for the next 50 years, that could still be a lot of fun. Please put your time and money where your mouth is, and make a better solution. I will be happy to cheer for you.richh",

Most of us can’t get that level of support, but I remember another Factory Five GTM kit that impressed his team, built by high schoolers and featured in Fast Times at West Philly High. They just missed the final cut for the Auto X-prise, but have done so much better at the Watkins Glen Green Grand Prix in 2012 perhttp://fuel-efficient-vehicles.org/energy-news/?p=28I’m retired and out of the game for now, but am interested in the technical and future affordability of projects like yours. Elon Musk has a reputation for calling HFC cars “Hydrogen Fool Cells” preferring to get his performance from a lot of battery capacity. I remember the HFC development vehicles that cost a reported $1.5 million (at the 2007 Shell EcoMarathon), but the Hyundai guy at the Solar Decathlon last year said they hope to have models in the $50,000 price range. Though the HFC vehicles are not high performance race cars, they do have me interested in competitions that emphasize streetable performance at anything near the fuel efficiency shown by the HFC EcoMarathon entry from the University of Nance though it didn’t compete with the ICE versions at the event. I believe the CalPoly San Louis Obispo entry was over 1,900 mpg, but the French HFC was almost 6 times better for equivalent mpg). Perhaps a Hyundai HFC setup in an old Kelmark GT a friend has (adding a super capacitor array to store recovered energy and provide quick bursts?",

This is
(video above) perhaps the most abstract way of playing sounds…ever. Yes, we’ve heard
Hard Drive music
and
Obsolete technology bands
, but [DJ Sures] brings us the first ever, spark plug instrument.
Much like
Velcro and Teflon
, the musical spark plug is claimed to be an accident. After testing energy use vs. spark power with his flare stack ignition controller, [DJ Sures] noticed that different frequencies could be produced. It was only a matter of reprogramming before
death metal
Twinkle Twinkle Little Star is heard. Now he just needs to refine it a bit and build a
full stereo cabinet

BAMF2010: SolarPump Charging Station

Amidst the noise of a bazillion robots and Tesla coils at the 2010 Bay Area Maker Faire, we located a bubble of usable WiFi, and got a nearby power charge to boot. If nothing else here, we want
this:
The
SolarPump Charging Station
is a self-contained oasis of free power for laptops, cel phones and even
electric bikes
. This charging station is one of several designs created by Sol Design Labs of sunny
Austin
, Texas. No bigger than a bus stop (and
way
cooler looking), it’s like the ultimate
case mod
, repurposing a vintage Citgo gas pump and recycled metals for more modern needs. Three large Sanyo
solar panels
provide power for devices and shade for users, while topping off the internal 24V 100AH battery for nighttime use (with LED lighting) or cloudy days. The end result transcends “green” — the SolarPump is simply appealing at a visceral level, managing to be simultaneously fun, attractive and practical. Did we mention wanting one? We
totally
want one.

We’d bet a large portion of our readers don’t remember when you could call the phone company and get the time of day. Gadget Gangster is bringing back the tried and true method with this
talking clock
. Just press the button and the ‘operator’ will read the time of day to you. Record your own voice and place the WAV files on an SD card, from there a Propeller chip takes care of the rest.
As a side note, we’re big fans of the method used to
breadboard the power supply
using the TO-220 package leads as their own jumpers. We’ve always been partial to using
a breadboard regulator on a PCB
but this method is simple and takes almost no space at all.

Composting To Create Hot Water
|

[
"compost",
"hot water",
"jean pain",
"methane"
] |
Want nature to supply you with 130-150 degree hot water? [Onestraw] shows you how to get just that by
building a compost heap that heats water
. Finding himself the proud owner of a dump truck of green wood chips [Onestraw] went about building his own version of
Jean Pain’s thermal compost pile
. The idea is to produce and store methane generated from the compost pile but in order to do so, the temperature must be kept fairly low. The microorganisms in the compost generate a lot of heat trying to break down that matter and running water through the system will keep the temperature low enough for the methane-producers to be happy. The side effect of this cooling system is hot water coming out the other end. [Onestraw] even has plans to use salvaged car radiators to turn the hot water into a heating system for his home. Granted you’re not going to add this to your apartment, but
if you have space and waste plant matter and need hot water
this is a great way to get it.
[Thanks Joel]

We hope you paid attention in advanced theoretical and quantum physics classes, or making your own Open Source
Scanning-Tunneling Microscope
might be a bit of a doozy. We’re not even going to try to begin to explain the device (honestly we slept through that course) beyond clarifying it is used for examining the molecular and atomic structure of surfaces; but for those still interested there is a nice breakdown of how
Scanning Tunneling Microscopy works
.
[Thanks Rich]

Z80 Emulated On PIC Hardware

[Jaromir Sukuba] built a very portable, low power consumption
Z80 emulator using a PIC microcontroller
. Looking through his build photos we love the clean and resilient construction which includes a breakout board for the PIC 32MX795F512H that interfaces with the main board via pin headers and sockets. He’s using a
home-built keyboard
and a 4×40 character display but there is also the option to communicate with the device over an RS232 connection. Oh, and yes it plays
Zork
, which seems to be the benchmark whether you are emulating
a Z80 with AVR hardware
, or if you
built one from transistor-transistor logic
.

Second reason for choosing this PIC was its 128kB of internal RAM – so I can run 64kB RAM virtual Z80 machine and huge RAM disk for CP/M. Adding external RAM to MCU lacking such as huge RAM would bring speed penalty, what more, device would be physically bigger. With PIC, it is only ONE(!) TQFP device – first revision of hardware had only two chips – PIC and MAX3232. Then I added external 128kB EEPROM and later I added FLASH, which is still not on pictures.I’m planning to bring more details (more info than just 17 pictures in flickr) about this device, and make its portable, hand-held version.The keyboard is made of single keys, salvaged from old computer, made in 80’s in former Czechoslovakia. There is a small PIC on board, outputting ASCII chars via USART for main PIC32.",

Hack A Day Store Now Open

Since the beginning of the universe we’ve been getting requests for stickers, shirts, coffee mugs, etc. Well, several of the writers have the ability to produce this stuff in their homes. The boss liked that and gave us his blessing to
start selling Hack a Day stuff
.
In the interest of keeping the cost as low as possible, right now the store is located inside of my personal online store. The only products we have right now are stickers, since I make them myself. Though if enough of you pester him, maybe [Devlin] will make up a batch of those
Hack a Day badges
.
Please be patient with the store. It is fairly untested and tossing this many people at it at once is somewhat frightening. If you have any problems at all, please contact me (caleb@) and I’ll take care of it. You can get to the store by clicking the new button on the right of the screen, labelled “store”. You can see a few more pictures after the break.
Note: Thos of you who are outside of the US, please just contact me directly. I have to figure out your shipping outside the system. Don’t go fill out an order.

Bay Area Maker Faire Blasts Off Saturday

It’s crunch time at California’s San Mateo Event Center, where crews are busily assembling rocket ships,
singing Tesla coils
and animatronic
giraffes
and dragons in preparation for the
2010 Bay Area Maker Faire
, taking place this weekend.
Returning for its fifth year, Maker Faire, if you’ve not had the pleasure, could be described as 50 percent science fair, 50 percent county fair and 50 percent
Burning Man
reunion. And if that doesn’t seem to add up, you’re right — it’s sensory overload, a hands-on, warranty-voiding explosion of futuristic technology, down-to-earth crafts and nine dollar pulled pork sandwiches.
If you’re planning on attending,
hit up their web site
for all the information on tickets and hours, recommendations for parking or — perhaps most importantly — public transit options. The event has been growing every year, even disrupting traffic on nearby U.S. Route 101, so you’ll want to set out early or research
alternative
options
. We’ll be posting goings-on from the event as it unfolds, connectivity permitting.

Power Drill Solder Spooler

[Scott] over at curiousinventor.com has posted an instructable detailing
how to use an Arduino and a power drill to spool solder
. The Arduino senses the speed that the drill is going via an opto interrupter and a laser and adjusts with a servo hooked to the trigger. While we don’t think many people will be dying to spool some solder, this system might be useful for all kinds of things, like
winding yarn
or
making coils
.

Strumming to punch and changing frets to move, [Alan Chatham]
plays Street Fighter using his guitar
. It’s been modified to use
OpenChord
, an open source guitar controller package he developed. This was originally meant to be used with Guitar Hero and the like but as he mentions in the video after the break, it is open source so you can do whatever you want with it. In this case, he’s patched into a PS3, showing yet another way to use your own hardware on that console. Unlike
alternative guitar-like interfaces
you won’t have to relearn how to play. You just need to adapt your favorite songs to fall in line with butt-kicking controller combos. For the adventurous
you can build your own
but [Alan’s] got kits available too.

Not willing to settle for 1400×1050 on his Thinkpad, [Lawrence Sheed] set out to
upgrade the LCD screen
. He ordered a 15″ replacement screen that brought the eye candy up to an impressive 2048×1536 QXGA format. The replacement fits perfectly for a nice factory look. Other than some delicate disassembly you might need to flash the EDID but in [Lawrence’s] case it wasn’t necessary. If you’re going to haul around a full-blown laptop it might as well have some killer resolution and now you know how to make that happen.

You CANNOT just replace any old TFT LCD panel with another. Your LVDS/TMDS controller needs to support it. Also your controller might used a fixed EDID data structure rather than dynamically filling in the details based on the panel specs. And yes that’s an amazing price for a screen that small with that resolution. So yes lucked out to the max.On a side note, does anyone know of any places that sell decent LCD controller boards based on the Genesis chipset. The only place I found was AgilentPixel but they don’t respond to emails.http://www.agilentpixel.com/product.php?id_product=26Thanks.PS. You have QVGA in your article when its actually QXGA.",

For 50$ I bought the new high res cable and installed the panel. The laptop immediately recognized the panel and now I have a 1920×1200 display. Very simple to do and well worth the upgrade.",

But until then, I prefer a screen of about 86ppi or .29mm dot pitch (1024×768@15in, 1440×900@20in, 1680×1050@23in,1920×1080@25.5in)To those of you trying to read on screens with higher than 120ppi, enjoy your good sight while you still have it.I have spent about 12 hours/day at a computer for about a decade straight.

This is my primary machine, and I love it. I’ll note that I have 20/20 eyesight in my left eye, and my right eye is about 20/120… but because it’s a lazy eye, I need bifocals to prevent eyestrain when focusing. But, this thing has been quite acceptable for occasional without glasses at all. My IBM T221, on the other hand… that needs glasses. 3840×2400, 22.2″.There’s only one reason I want resolution independent UIs – so that LCD makers will make high-resolution panels again. I’ll make everything so it’s the same pixel size that it is today, and take advantage of the drastically improved working area. (And, Windows 7 is about 95% resolution independent with Aero.)",

I’ve seen plenty of things where issues like dialog buttons disappear off the edge of a non-resizable window.The issue is, too many developers shape applications with the assumption that the size of text will never change. This means that when you just increase font sizes, things break. Sometimes to the point where they are unusable.So, here’s hoping for resolution independence. I wish my eyes could handle a 170 ppi screen… but that’s just not going to work for me. I’m sure it’s very helpful for productivity though.

Solder Station Hack Adds Temperature Control

Take that cheap fire stick you call a soldering iron and turn it into a real tool. [Giorgos Lazaridis] turned his 30 watt soldering iron into
a temperature controlled soldering station
by adding a thermistor just above the tip to monitor how hot things are getting. A MAX6675 takes care of the thermocouple and shoots a digital temperature value off to the PIC 16F88 which controls the unit by taking user input from a potentiometer and displaying the settings on an HD44780 character display. His use of a dissected ‘wall wort’ inside of the ATX power supply carcass used as the case for the station is a clever hack. See it melt some metal in the clip after the break.
This makes a nice upgrade to
our solder station guide
, which had a temperature controlled iron but lacked the sensor and automation seen here.

If you select a light-work PID, it can choose more agressive anti-overshoot parameters (with the downside of getting you jammed if you try solder a lug-nut :-) You could make it beep if you wanted to….I too have a cheap station, the controller is crap, and beside overshoot sometimes gets confused. Once it’s outside the 1-year warranty I am going to rip its guts and come visit this article for inspiration again. It’s good to know that the pulse driving mechanism can get you there.

Here’s a
slick version of a POV globe
(
google translated
). Created by [Riko], this globe has 32 LEDs and is powered by a rotating coil. The layout looks fairly solid in operation, with the POV effect showing up very nicely on camera. You can get the schematics and source code from the project page.
We found this project, just like the previous
fantastic LED globe
on
HackedGadgets.com
. Apparently someone linked to this project in the comments. That is fantastic, that is what the comments should be for. Please help keep our comments polite and helpful as well, even if you are just linking to a project that you think is better.

This
two handed glove input
setup, by [Sean Chen] and [Evan Levine], is one step closer to achieving that [
Tony Stark
] like workstation; IE, interacting with software in 3D with simple hand gestures. Dubbed the Mister Gloves, the system incorporates accelerometer, push button, and flex sensor data over RF where an MCU converts it to a standard USB device, meaning no drivers are needed and a windows PC can recognize it as a standard keyboard and mouse. Catch a video of Mister Gloves playing portal after the jump.
While amazing, we’re left wondering if
gesture setups
are really viable options considering one’s arm(s) surly would get tired?

"content": "I notice we’re getting quite a few posts out of the Cornell ECE 4760 class projects page lately.“Gorilla Arm” is a potential issue, yes.I conceive of gestural systems as one option among a multimodal interaction toolset, which is to say that they should be used where most convenient or when most suited to a task but that you shouldn’t force users into using them extensively or exclusively. For a somewhat analogous case, consider the keyboard and mouse. There are many things which you can do with both devices, and in these cases the user is free to choose according to comfort or just according to where ever their hands happen to be resting. There are other cases where one or the other is particularly suited. For example when inputting text it is possible to use the mouse but much more efficient and comfortable to use the keyboard.Good HCI is not about providing something novel, it is about providing something which improves the comfort or efficiency of the interface, or extends its function. Neither is “the interface” simply your new device – it’s the complex of all physical and cognitive factors involved in your interaction with the machine. This almost always involves the melding of several modes of interaction to form a (semi)coherent whole, and it is here that we may find use for things like gestural input.That and sign language.",
