Hello there,
Sorry, I'm new to this forum, and to electronics in general, and was after some help. Essentially, I'm a professional magician, and in my spare time I like making stuff - it sort of comes with the territory. Anyway, I've recently got into making the occasional electronic gadget to help with my otherwise totally legitimate magical powers, and was looking for some help.
Essentially, I was wondering if someone could point me in the direction of something to educate me regarding building small transmitters/receivers that could work over a reasonably short range (about 20ft maximum). They don't need to send any information or anything, just an on or off kind of deal. Ideally the circuits I'm looking to build need to be small enough to be secreted about my person.
Any help/ideas?
Thanks very much,
Rob West
