[Jared]’s back in action over at Inventgeek. Now he’s got an odd use for an old LCD: creating an ultraviolet light polarizing table. He gutted the LCD and swapped out the CCFL lams for some UV versions. The result isn’t much more than an interesting conversation piece, but it’s nice to see a use for screens that would otherwise end up in the recycle bin.

24th Anniversary Macintosh
[Dave] sent in his retro Mac project. Putting new guts into an old mac isn’t really unheard of, but I liked his solution to use the original Mac 512k keyboard and mouse. He used an Atmel AT90USB162 to create his own standard USB HID device. The keyboard and mouse appear as a standard USB device, so the mac (or any modern USB PC) can identify use the keyboard and mouse without any additional software.
NTP Alarm Clock
[bifferos] just found us, but he sent in his NTP alarm clock. It’s actually a Sweex LB200021 router with a custom display driver to display 24 hour time. Given my love of NTP, I couldn’t resist posting this one.
Friday Night Double Cap Extra
[scott] sent along his lego ipod dock.
The letter [M] brings us the oscilloscope terminal (AVR based text displayed via oscope).
[Max] sent in his funky alarm clock mod.
[Chad] sent in a question, but I dig his custom camera housings.
[sprite_tm] sent in his new use for a cheap photo display.
UPDATE: Torrents for all the talks at the Chaos Communication Congress have been posted.
Electric Roach Motel
[Luhan] built this PIC controlled roach motel. It’s the first micro-controller project that I’ve seen devoted to exterminating a member of the insect world. A PIC 16F675 is used to generate 10 pulses at 400 volts per second. Crispy.
Great Intro To Surface Mount Soldering
[Scott] sent in his video how-to on surface mount soldering. The macro video quality is excellent, and the demo is great even if you’re already into SMD work. Everything can be done with fine solder, a decent soldering station, tweezers, a 10x loupe and a good selection of flux. I’ve managed quite a bit of SMD work without external flux, but this sort of demo shows just how effective it is.
How To Make A Vacuum Tube
[marco] sent in this video (scroll down) showing how to make a vacuum tube by hand. The page and captions are in french, but it’s pretty interesting to watch. A small spot welder, some fairly basic glass working tools and a vacuum generator are required, but the technology is definitely within reach for the dedicated hardware hacker.
