pentium powered extra with friggin’ lasers

[Neil] sent along this one and I found this one highly amusing. The latest use for recycling those old cpus: overvolt them a bit with a USB cable and keep your coffee cup warm. Use them as dressing for heat generating resistors.

[nik] came up with a non-destructive way to mount an external wi-fi antenna to his thinkpad. I like it, but I think you need a double height PCMCIA slot to fit it – Maybe a slimmer version could be built for a powerbook/macbook.

[Hybrid] found some interesting diy LASER projects. Including a $10 air laser. Sweet.

[joek1010] noted some interesting webcam laser hacks. The laser tracing webcam has definite possibilities.

[dualbandit] found a similar twist, but this time a laser pointer is used to remote control a mediacenter.

In case you’ve been following it, my DIY HD projector build on Engadget is finished up with the final review. I’m pleased with the image quality, but I’ll probably be tweaking the lamp/reflector assembly a bit.

Oh, and if you were into exploiting vending machines and getting free coke, it looks like they’ve pushed out a firmware patch.
