These are Gray Codes, different ways of changing a binary value such that every value is visited just once, while also ensuring that only one bit is changed at a time.

And I'm adding a speed control potentiometer in one of the blanks. And an e-stop. Should be a pretty fun thing for smaller kids to whale on at Open Sauce next year!

This remembers me when in the '70 we made experiments with DIY "disco ligths".

Probably didn't even need the relays. Now I just have to wait for the control panel to arrive. (The final version will probably cycle much more slowly, this was just for testing.)

It looks like a Godzilla resistor 😄

And I'd been meaning to do something with a stack light/tower light (used on big factory floors to signal machine states like "error" or "running low on parts") since they're so visually iconic. So I grabbed a cheap one off Ali Express to play with. I wish it had more tiers, but any past 5 get very expensive very quickly. I'll keep an eye on ebay to see if some turn up, but this will do for now.
