micro wireless switch??

Does it exist?

Essentially I have a couple LED lights that I am trying to turn on and off independently.... wirelessly.

Power source for the lights are CR2032 batteries, and maybe the same for the switch.

By "micro" are you saying a microprocessor is involved?

Here's a kit that allows you to turn on/off the yellow LED on the board with your Bluetooth Android device. Of course it can do a lot more if you build some of your own HW upon it:

(This one uses a microchip.com PIC processor.)

If you don't have an Android you can use a couple of these kits:

I believe they will talk to one another over something like a wireless star network. But read up on it - it's been a while. (This one uses a ti.com MPS430 processor.)

I think you can download the SDK for either processor for free. And I think you can program either in C. I don't think either setup uses an OS. That is, you are running the show. Some like it that way. Others like operating inside of an OS (like on a RaspberryPi). Of course, the YOYO design (what the 1st device above is based on) doesn't really want you to change the PIC code - but rather the Android code (which is an entirely different subject).

Are you perhaps doing something like this: http://www.aliexpress.com/store/group/W ... 85775.html

Or similar? Could probably find one available in small quantities and rip out and hack the guts.

Or if you're putting together something yourself you might find something like this: http://www.dx.com/p/433mhz-rf-transmitt ... -RJMvldXgg

I hear Sparkfun is sold out on this kind of thing though. Don't know about replacements and I haven't got any for myself yet.
