My show, For Amusement Only, has quite a bit of tech - all related to EM games. Cleaning and adjusting switches, disassembling and assembling, lubricating steppers, reading schematics, troubleshooting, and much more. Currently, I am building a few different games, and talking about the challenges involved with that.
I've also interviewed dozens of restorers, mechanics, and engineers (and one designer), and always talk tech with them.
Over 430 episodes, generally bite-sized, speaking about a specific problem/issue per episode, typically. Some of the games I'm building are solid state with LCD displays, and I speak about technical (wiring) challenges, drawing schematics, and programming issues (including animations).
