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.

Any ideas?

To clarify, I have looked around, but most units I'm finding cost around $50, and have way more features and bandwidth than I need. Looking for something very lo-fi here. I considered bluetooth, as I know there are integrated solutions, but it seems like overkill.

Well, my lecturers (100 years ago) used to mention the frequency bands between "DC and daylight" ... is that what you mean ? :lol:

Anyway, rather than messing with you, I will point you at

Should be cheap enough.

I was referring to the fact that human vision has a threshold at which small differences are not so visible. I guess I could have just said the application is not super time sensitive.

Messing aside, that unit looks awesome. I'll look around to see if anyone else carries it (Sparkfun's shipping to Canada is murder, I learned this on that day they gave away 100 in free stuff and the shipping was almost 50).

I'm not sure if IR can go through a cotton glove, clever idea though.

IR can go through a cotton bedsheet. I flip TV channels like that all the time. Keeps my hands warm.
Shutting up now.

What are you doing with that remote under the bedsheets?

Perhaps it doubles as a sex toy. :)
