La Fonera with IR receiver
Hardware part is very simple. You need an AVR Attiny2313 from Atmel, a TSOP1736 receiver, a 14.7475 Mhz quartz, 22pf ceramic capacitors and, if you want, led and 330 Ohm resistor. You can also use internal 8 Mhz resonator from the AVR (low speed, 9600bps) but you will get better results with a quartz (115200bps, see page 140 of the Attiny2313 datasheet).
