Perhaps you and the makers would be interested in this very quick write up on how to get an LED to be both a light and a touch sensor.” – Link.

haute! I’ve been wanting to build one of these.
I wish someone would just capture an audio stream of the IR signal a TV-B-Gone makes. Then you could put a wav file of it on any audio device and us an IR LED hooked up to the audio out port of the device and bingo you have a TV-B-Gone. I’m tempted to buy one just to put the stream out there for others with the same idea.
The audio wave idea is kinda good, but you’ll have to have a good playing device for it as the frequency may be a bit high or low
But this one is kinda easy to build and I’m sure you can do it with 10FXXX in DIP package witch make it even better for beginer.
