I've always been fascinated by the concept of carrying data and power on the same two wires. This has so many advantages for small networks that need simple wires and connectors -- or waterproof connectors.

I build a test someone else On-Off Keying schematic and find good results. Could this be an on bike rival to E-tube that could be open?
