[Sprite_tm] sent in his latest project. It’s a cluster built from hacked Acer WT-300 windows CE terminals. The resulting speed wasn’t too impressive (10 200Mhz Geode cpus) but the road to get it done is interesting. He had to whip up a flash programmer to get the device to boot from ide devices. Then he added IDE headers and IDE Cf adapters.

Humidor Cluster
This mini-itx mod is pretty slick. It looks great, but inside you’ll find no less than five mobos, an ethernet switch complete with five hard drives. The controller is a Via PD1000 and the four slave machines are Via V8000As.
[yeah, I forgot to publish it earlier. Four words: Two Week Old Baby.]
Ion System Cooling
Jared sent us his latest inventgeek project. We love their work, and this one’s really unique. By combining the ion cooling, lots of heat sinks and ram drives, the machine is truly silent. Ion buildup isn’t just a problem for space ships anymore.
More Keyboard Lighting
[sfriswolker] sent in his progressing black keyboard lighting mod. The first version used a CCFL. When that burnt out, he rebuilt it with LEDs. [google english transations – part 1 and part 2]
Linux On Obsolete Displays
[bryan chafy] has been hacking away to get older non VGA displays running on VGA hardware without using a scan converter. You can pick these old grayscales up for cheap or even free. The tricky part is modifying the BIOS to reprogram the VGA card to output a sync and scanrate that is NTSC compliant. He’s managed to do this with a WYSE Winterm thin-client. Another clever trick is the poor man’s triple head display which stores a different image in each portion of the RGB signal.
Hard Drive Oscilloscope
[hackgadgets.com is back up… maybe]
[Alan] put together a list of the Top 5 Dead Hard Drive Projects. He suggested we post about the hard drive laser oscilloscope, since he couldn’t find the project anywhere else. I actually saw a similar project during dorkbot-sf‘s presentation at Maker Faire. A laser is mounted to the drive case. The beam is bounced off of a mirror connected to the read/write head. He’s got a video of it in action on his site. Have a look at the other hard drive projects as well.
Phase Change Cooling System
Chris Morrell has an impressive write up on all the ins and outs of building a phase change cooling system. Vapor refrigeration moves heat from one area to another by changing the phase of the working fluid. Chris used propane as the working fluid in his system. He’s got instructions covering all of the work involved from brazing the copper tubes, to building and lapping the evaporator blocks, to the final tuning. With no load it’s can hit -45DegC.
This story reminded me to check back on extremecorvette’s cascading cooler from last fall. He started receiving parts last month for a brand new design. I can’t wait to see how that turns out.
