davedarkoI'm thinking of using a servo that turns a wheel with little pictures in it and put a little LED behind it.
LED projector
A project log for R8-D8 - a distant relative of R2-D2
a 12cm radius, 3d printed R2-D2 with some motors, servos and blinky stuff that follows lines, persons or just drives around via bluetooth

Great idea! Would a CR servo turn it quick enough to look like it's animated or would a DC motor with pwm control be better suited for that kind of shenanigan?

been meaning to get some tiny little translucent grayscale LCD displays running for some sort of projection... They were 5 for $2, so I couldn't pass 'em up! Something like this'd be a good use for 'em.

sounds cool :) I hope I'll get away with an LED and a printed on overhead projector foil.

Sounds doable, and cool!
