More pixel art inspiration from The Art of Computer Programming (volume 4A). 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.

I was thinking it could make for a fun little interactive piece to have something cycling through all combinations of its lights following different Gray Codes. 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.

Maybe mounted on a control panel something like this...

It looks like a Godzilla resistor

Well, that was easy. 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.)

@attoparsec but it sounds cool with the relays!
-
@mattieuMattieu Yeah, I'm pretty sure I'm going to keep them just for that. :)

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

The control panel has arrived and looks great, but it turns out you can get those "legend plates" custom made pretty cheaply, so I'm getting a set made for the six different algorithms for sequencing the lights. 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!
