clicker finder

[Locutus]

Hey all,

Haven't really dabbled in electronics projects since highschool (lets just
say a long time ago) and I am looking to do a simple project for fun and to
get back into it a little. I thought a neat/fun little project to start off
with would be some sort of "clicker finder" because I am always losing that
remote to the TV! lol...

I was thinking just a little rf transmitter and receiver, doesn't need much
range, maybe 20 feet? I think there are already products like this on the
market, but I don't want to buy something, as that really isn't the point.


Are there plans out on the net somewhere for something like this already? If
someone could point me in the right direction I would appreciate it!!

this is basically what I would like to make:

small device = small antenna = high freq = problems 4 u
big antenna = lower freq = less probs
small coil with many turns at low freq + short range = might be good
enough = ULF/ELF

ultrasonic = best bet perhaps

Get it, for $29.95 you won't be able to make one. But I doubt you'll be able
to do a RF circuit at all if you already have to ask in this group. There
used to be these key-chain beepers activated by clapping or whistling.
Much cheaper and you do not need a transmitter which no doubt gets lost as
well in your mess. :-(

keep searching

What about the ancient 'keychain finders' that whistle back at you? No
transmitter to lose, and they were really clever designs with a minimal
number of active parts and low battery consumption...
ISTR they only used a 4000 series chip - quad nor or something?

there you go. easier than ultrasonic or ELF.
