SiLight writes – “SI-Light is a experimental computer controlled home lighting system. It started with the goal of individually addressable RGB light modules that could be used to tie-dye or acid-warp my studio apartment. It is a combination of hardware, firmware, and software that was written over a few days in the summer of 2005, though it took considerably more time to etch, assemble, and install the PCBs.
The system is based on chips I used in various professional projects, such as the mighty PIC 16f628(a), and the killer TLC5940 16 channel PWM chip. Soft/firmware is written in basic – everything is pretty high level and I didn’t want to mess with C for a weekend project.” Link.
