Nice and simple solution for those who need one direction data transfers only.

I'm hoping this will all be instantiated in a rather more practical package involving some Raspberry Pis, using the GPIO or something. Sounds like a nice little project for some student group.

 

That's on my list. I got side-tracked by learning how to measure RF leakage. I'm no EE
