I made this circuit around 7 months back and have been using it regularly since then. It is basically two relays that can be controlled by an IR remote. The relays in turn switch a fan and a light source. What I like most about this project is that I can program it to use any IR remote. Since I have installed this in my living room, I now use previously unused keys on my TV remote and set top box remote to control the relays.
Planning to soon make a circuit to replace an entire typical switchboard with relay or triac based switching and wall panel with capacitive sensors.
