Radio Controlled Switch ?? Schematic

[steve]

I want to make a radio controlled switch to turn off 120 Volt lights.

I have found things like this transmitter ...

http://www.reconnsworld.com/transmit/simplerf.gif

But it has no receiver ?? Or at least I'm not sure how you are suppose
to use it.

My thought is that I would build a simple transmitter, and receiver and
add to the receiver some circuit that would pick up the signal and
eventually turn on a relay to turn on the lights. It only has to travel
about 10 feet.

Has anyone seen schematics for this, and by the way. I don't want IR
because the switch is not in line of sight.

Thanks.

You can buy gadgets like this that provide an RF switch to control lamps. I
use one to have a switch inside that can control the christmas lights on the
outside of the house.

I used garage door transmittor switches. They use encoder bits,
so a change unwanted signal is less likely to trigger your
switch. Also it had 3 separate buttons, so you can use it
for other things.
The reciever had 3 nice relays,so you can swith whatever you
want.
Th encoding was done with 8 tristate swiches,or 512 encoding
options.

Yes I have one myself. I just wanted to try to build somthing and learn
a little.

Unfortunetely I don't have any old garage door openers. I was trying to
find some circuit that I could build that would be relatively simple

Try here:

He has some transmitters, but they are more of a near-field experience. It
should be fine over 10 feet, if you can get it to work.

You can also buy matched transmitter-receiver pairs here, that work fairly
well, and are very easy to interface:

They are basically the same radios they put in key fobs for autos.

Thanks Bob I will take a look.

Unfortunetely I don't have any old garage door openers. I was trying to
find some circuit that I could build that would be relatively simple

you can get auxillary receiver modules from manufacturers.
one that I've used is the one from dominator which provides 4 latching or
momentary low power relay outputs, but uses proprietary transmitters not
the gereic ones with code switches.

Thanks I will take a look for them.
