World’s smallest low-speed USB analyzer (works as a USB key recorder too)...
Chinook writes -
[Any] idea is dead without a good application for it. So “California Dreamin’” USB virtual peripheral could be a very nice sample of academic research, but hardly anybody is going to build a keyboard or mouse using it. I have been thinking for a while what to do with it as well. First project that came to my mind was building a hardware key logger for USB keyboards, something like www.keyghost.com, built for PS2 protocol using PIC16F877. It was quite simple to implement USB part using SX, serial EEPROM and a few switching IC’s. Furthermore I found out that built-in features of SX MCU would help to create a device able to work not only with pure low-speed USB keyboards, but also composite, built-in-hub, things, hence covering all existing systems (SUN, Mac, PC). Recording keystrokes is fun, but if we can do that, why not go further and try to record all low-speed USB traffic. No problem for SX again, problem for the memory. Serial EEPROM is just to slow to handle it. Solution was www.ramtron.com FRAM with 1MHz two-wire interface (let me pay credit here to www.svtehs.com, who happens to advertise it). Finally “California Dreamin’” found a real life application in the world’s smallest low-speed USB analyzer “Atapchi” (stands for a small fruit in Singapore, tastes like apricot). I hope you find this project interesting.World’s smallest low-speed USB analyzer - Link.

uDuino: A very low cost Arduino compatible development board
Tymm writes -
Arduino boards are great for prototyping. However they get rather expensive when you have multiple concurrent projects or need lots of controller boards for a larger project. There are some great, cheaper alternatives (Boarduino, Freeduino) but the costs still add up when you need many of them.uDuino: A very low cost Arduino compatible development board - Link.This is a way, after about $25-$30 initial investment, to build sub-$10 Arduino-compatible boards with very little extra time investment on each.
Note that the basic idea here (Arduino on a breadboard) has been done for quite some time (e.g ITP Arduino Breadboard instructions); however the cable adapter build & usage instructions here help absolutely minimize the parts count for each core.
This project requires knowledge of soldering and basic electronics, and you should have at least some experience already with Arduino development. I don't suggest this as a first electronics project.
note: I pronounce uDuino "moo DWEE noh"
This Instructable is still a little under development; if you notice anything missing or have suggestions for things that should be added please let me know. I've left off some notes about potential uses/tweaks to keep the build relatively simple (I might put together another Instructable at some point based on some of the programming & testing tools I've been working on with this setup).

DIY Binary clock project & binary clock roundup!
Dave sent in his binary clock he turned in to an old hard drive, he writes -
In about April of 2004 I started this binary clock project which was inspired by the Think Geek binary clock. I put the project on hold a number of times and finally finished it around October of 2003. When I started the project the TG clock was only available with red LEDs, and while it was definitely pretty cool, there were a number of things about it that bothered me. Obviously it needed blue LEDs, which are all the rage for the modern appliances. It also displays the time in 6 binary registers, one each for the 6 decimal digits of a digital clock. While this arrangement generates some pretty gnarly patterns, and is probably why it was chosen, it seemed very un-geekish to me. Lastly, and most importantly, since one of the guys I work with already had a red TG binary clock on his desk, if I was to have one, it couldn't be the same design, and it would have to somehow out-geek that other clock.DIY Binary clock project - Link.Clearly I would have to create my own binary clock from scratch to meet my requirements. As the only 'crossover geek' in the office (programming and hobby-level digital electronics), I could meet the primary goal of out-geeking the existing clock with my own AVR microcontroller based design.

HOW TO - Make a 99000 RPM digital contact-less tachometer
Ibrahim writes -
how to build a contact -less tachometer (device used to count the revolutions per minute of a rotating shaft) using a 8051 micro controller and a proximity sensor.HOW TO - Make a 99000 RPM digital contact-less tachometer - Link.As the name implies, what makes this device special, is that it can very accurately measure the rotational speed of a shaft without even touching it. This is very interesting when making direct contact with the rotating shaft is not an option or will reduce the velocity of the shaft, giving faulty readings.

Bubblegum sequencer - Making music with candy
Hannes Hesse & Andrew McDiarmid sent in this sweet project! -
The Bubblegum Sequencer is a physical step sequencer that lets you create drumloops by arranging colored balls on a tangible surface. It generates MIDI events and can be used as an input device to control audio hardware and software. Finally, people can't claim anymore that electronic music isn't handmade.Bubblegum sequencer - Making music with candy - Link.Here's how it works: A grid of holes, consisting of several rows with 16 holes each is the canvas. On it, you arrange colored gumballs. The 16 columns represent the 16th-notes in a measure. Each color is mapped to a specific sample.
Because the output is generated in the form of MIDI events, the Bubblegum Sequencer can be used to control any kind of audio hardware or software.
If you'd like to know more about the Bubblegum Sequencer, read our paper (CHI 2008 Extended Abstract Format).

HOW TO - Disable navigation lockout on Ford cars (and possibly most others)
Jason @ Hackszine is on a nav-system-lockout disabling roll, he writes -
After my post last week about disabling the navigation lockout on Lexus and Toyota nav systems, I received a request from an unhappy Ford owner with the same problem.HOW TO - Disable navigation lockout on Ford cars (and possibly most others) - Link.After a bit of searching, I unfortunately wasn't able to turn up any straightforward "secret-password" solution for this. What I did find, however, is a straightforward hardware modification that will put you back in control of your navigation technology. Assuming you don't mind rolling up your sleeves and disassembling your dash, this fix is known to work with a couple Ford truck models, and I have a feeling that the same method might be a general solution for almost all factory navigation systems that have this lockout functionality.
The navigation system uses a connection to the Vehicle Speed Sensor (VSS) to determine whether or not the vehicle is moving. By installing a small switch that can disable this connection, you can trick the navigation system into thinking the vehicle isn't moving (apparently it doesn't think to double check your speed with the GPS unit). Turn the switch off and you can enter your destination information. Flip the switch back on and your navigation system is back to normal and tracking vehicle speed correctly.
Now here's the interesting bit. It looks like factory navigation systems for many other vehicles use a VSS connection to determine speed. While the particulars of removing the dash and locating the VSS wire will be different, chances are good that this hack will work as a last-ditch effort in fixing navigation systems that don't have a software override (hear that 2007-08 Lexus and Toyota owners?).

RoboChumby
Over the holiday Bunnie made a robo-Chumby, he writes -
The final control paths for the system thus looked like this:RoboChumby - Link.sensors -> chumby server app -> UDP packet -> 802.11 wifi transmitted over 10's of meters -> client client app -> phidget driver -> USB -> phidget board -> solid state relay -> RC controller switches -> modulated to 27 MHz -> transmitted over a distance of 1″ -> demodulated -> motor driver -> motors
Sony DSC-T10 camera -> PAL -> DVB-T encoder -> MPEG-2 format -> DVB-T wireless transmission over 10's of meters -> DVB-T receiver
Plus, of course, the normal widget stream coming from the chumby servers in the US via the Wifi interface as well. After all, what Wifi controlled toy car isn't complete without streaming internet radio, Flash movies of Chuck Norris facts and "interesting" Flickr streams playing on it.
