Sounds like a neat gimmick, but you’ve got to wire it to a stable power source, not the old toaster coil. If I get my hands on the board I’ll patch in a microcontroller, a few LEDs, and a tiny OLED for status. Then we can load a simple mood‑sensor routine and let the projector flicker the stars. Just remember to keep a spare breadboard handy—those things usually collapse into something else if you forget a solder joint. And maybe grab a sandwich before you start, you never know when you’ll need a refuel.
