Thanks, I'll look into those. Another gentleman suggest one of the 8x8 matrix switches.

I have the transistors, hundreds of them, so I'll start with those. I also have a
Fubarino (PIC32 based Arduino) also to start with. I don't know if it can handle USB
directly but I can start with serial.

I've given up on X10 and Insteon. as the Power Line devices age the signal weakens.
I've switched to ZigBee, Z-Wave and WiFi. This has been much more reliable. I'm no
longer using Mr. House. I've switch over to some custom node-red (Javascript) software.
I like it. :-)
