This isn't quite what you asked for, but as a kid who grew up on Lego Mindstorms I would have loved to have Spintronics back then: https://upperstory.com/en/spintronics/ https://upperstory.com/en/spintronics/ This is more about learning about electicity in a tangible physical way, using puzzles to learn -- so it's maybe a level lower than your intent, but it is for kids 8 and up and seems like even adults could learn quite a bit from it. It's really hard to describe though - I strongly recommend watching the video at that link or at least looking at a picture.
