Surely we can do better! 3 chips?!

Who's got a Prop, 2 servos, and an Etch-a-sketch laying around?

Cheers,

Would a CR servo or a stepper motor be better for this?

3 chips: one processor and two stepper drivers, you at least need amps.

What about an electronic etch a sketch with tv or vga output and two rotary encoders, mabye a pot to change the color? You could even have the cursor auto reflect when it hit any boundry.

how about connecting this to a bot, instead of a mouse, use encoders and have it draw where it path as it travels? sort of a mechanical LCD screen.
