I have need of a simple wireless connection between two devices for the purpose of synchronization. Since the output is intended to be within visible frequencies, I don't think super accurate timing is important.
The project is basically two lighting setups worn on the hands. All I need is for one hand to tell the other hand when it's time to switch programs (basically sending an interrupt without wires). Because the device will be worn, I'm hoping this transceiver can be small... and because I'm a hobbyist, within a reasonable price range.
