Powering a WiFi webcam…?
Brendan writes “I’m working on a little homegrown project centred around a creative use of a wireless webcam. Key to the project is the portability of the webcam. But there in lies the snag – power. I could go the iSight – laptop route which would work, and no need for power cables but ideally I’d love to have something that wasn’t as bulky. So anyway I was thinking would it be possible to wire up some hand crank power to a wireless webcam? Even if it only gave power for a half hour or so? Have you ever seen anything like this?” You could just wire up a 9v battery with a 5v voltage regulator (or whatever voltage the wireless web cam requires). Post your suggestions in the comments!
The Goldfish Online has some really interesting LEGO logic gates – “…designed working NOT, OR, NOR, AND, and NAND gates. Using two NAND gates I have produced a NAND gate latch or Flip-FLop. The natural follow on from these is clocked logic, full-adders and ultimately a genuine “computer” device. At the moment all these gates essentially just demonstrators. They work, but because of the limitations that arise through gear slippage, the real practicable use is probably not that great.” The details of logic gates can be found here – 
Dennis on the Amiga forums is building a mini Amiga. He writes – “I bought a Spartan-3 FGPA development board, learned Verilog (after finding out that VHDL was not my cup of tea) and started working on Minimig. Minimig stands for (very originally ) mini Amiga. My aim with Minimig is to built a complete OCS A500 (with some extra grunt and features like 4Mbyte ram and fast 68000 processor) on a circuit board about the size of a floppy drive. Loading of programs will be done by means of a MMC flash card, which holds the .ADF images of the floppies like a sort of hardware UAE!” [

TheDude06 writes “I finally completed my wireless guitar hero controller mod! With so much space available in the guitar, i knew it was possible. id just never got around to finally doing it. Long story short, i had to completely dismantle the guts of the guitar to do this. its not possible to do this mod without soldering or removing parts from the guitar hero board…. at least, not the way i dd it. Since i wasnt able to find a box that could turn any controller into a wireless controller locally, i figured id take a stab with these…” 
Flickr member Filmosity’s modded a CVS disposable video camera to include a built-in USB cable for easy transfer of video – “…Side view of the CVS One time use Camcorder, hacked with a USB Cable. The cable now has some velcro that keeps it flush to the side of the cam. Still a few more mods I’m going to make to the cam, including changing the logos that show up when you turn the cam on and off.” 
Tom made a pretty spiffy Ubuntu (Linux) home media center. He writes – “Like a lot of people nowadays, I have a growing collection of digital media. My digital media is stored on a home Linux server. Most of the digital media players available today do not support protocols to connect to a Linux server, which make them unsuitable for my use. I realized the best way to connect my digital media library with my home theatre was to build my own Linux home media center (LHMC)…” [
