So this all started right after Thanksgiving 2025 when it was time to put up the Christmas tree. Normally, we put the old Lionel train in a boring circle around the tree. That is about all the room I have for it. So I decided to get some N-scale trains so I could be more ambitious with a train layout. So what kind of scene do we build? Sleepy Christmas village? Nah, Godzilla smashing things up, of course. So I had the idea of taking an 8" Bandai Godzilla Minus 1 Ichibansho Figure
Godzilla and building a diorama around him. But then I had the idea of making his dorsal fins light up with a NeoPixel strip. This meant learning how to use a microcontroller and making the lights do the atomic breath pattern. And I was hooked. So the trains are now put away, and I have been working on a system for putting action figures on a stepper motor controlled turntable. That system has a dedicated esp32-s3 with a tmc2209 stepper driver and a basic NEMA 17 stepper motor that is accurately positioned using an AS5600 magnetic encoder. Using WiFi, I control the turntable with a built-in web app or via Python software running on my Mac or Raspberry Pi 5. The software can choreograph mock battles, or silly dance routines. It also allows me to use a PS4 Dual Shock controller to manually control the turntable.
