Scaling up for production is rarely as easy as just making 20x the same thing. In this case I was asked to make 20 of the moving BB8 cake heads. I changed the design in several places to make assembly easier, switched out the controller for a different arduino (and then changed it back again) and finally rewrote the control code to make it more obvious that all the functions were working correctly. It's been a bit of a long slog this weekend but seeing them all lined up on bench this morning was pretty rewarding and I can't wait to see them all when they're done in cake.
