Anything wrong with running the signal through a full-bridge rectifier?  They're cheap, and fast enough.  S.   PS - ever seen the YouTube channel of "The DCC Guy"?

Imho, edge connectors need gold plating.  S.

Polarity Insensitive Serial Comms
Incidentally, if you're willing to 'hit it hard enough', you can send the power along with the signal.  Just put a little AC on as 'line idle', and transform'n'rectify it...

Morse Code.  Send the signal as alternating current - AC, and use OOK signalling.  S.

PWM on all pins
The LynxMotion SSC-32 runs no less than 32 servos off an ATmega168.  It uses some external hardware (look like latches) because there aren't that many pins, and some very...

PAL - a modern equivalent for combinational logic
If you really want to demonstrate logic, build a Babbage engine.    Static power consumption zero, dynamic power consumption limited by how hard you feel like cranking...

PAL - a modern equivalent for combinational logic
Must admit I quit using discrete logic chips (with a few exceptions) in the 16[R/L][2/4/6/8/8] days (before the turn of the century), all in 20-pin DIPs.  A 24-pin 22V10 was...
