So far I’ve designed three PCB (printed circuit boards) for various purposes.  Each a little more complicated than the previous.

One of my latest designs – uses ATMEGA 128 3.3v with various sensors, FTDI USB interface, 5 volt LCD interface and a microSD socket. The firmware supports a boot loader for uploading new firmware automatically from a microSD card at power up. Also contains an IR receiver for decoding Sony remote control codes.
