[Ian] put up his RGB LED color changer project over at diylife. It’s a pretty simple project, but well designed and flexible for combining with other projects. He used a PIC18F2550 to drive everything, and some FETs to drive the LEDs. When you connect a USB cable, the color cycling project stops and the PIC responds to simple hex based color commands.

[Matt] sent in this excellent wifi finder reverse engineering project. The goal is to enable custom embedded apps that take advantage of the independent operating mode of the wireless adapter. One of the chips lacked any useful manufacturer markings, so he got some guys at a lab to etch the top of the chip off and get a partial chip id. So far he’s got boot-loader access, so now it’s just a matter of some development.

[Artur] sent in this instructable showing how to make your own back-lighting for LCD displays. It’s a simple process, but I thought it deserved some attention given the cost difference for back-lit LCDs. It’s also a good exercise if you’re building your own projector and considering removing the polarizing film.

[C.K.] passed along this impressive writeup on modding an eeePC for just about everything you can think to add. This one’s got two four port USB hubs, internal GPS, bluetooth, 56k modem, FM audio transmitter, 4gb USB flash drive and a 801.11a/b/g/n card with a spare antenna for full 802.11n support. The wiring job looks excellent – very clean and well done. The only thing missing is a touchscreen.

[Forrest] sent in his Hammonator Organ that he resurrected into a guitar amp. He re-used several of the original parts, and designed the amplifier around them. Tubes were chosen to fit the sockets, and the original transformer was adapted to run on the 120V usually found today.
