Tiny Tim

Sort of working from end to start, but here is a system design that I had in mind while throwing it together.

Next up will be adding in a small metal gripper so Tim can move things around... https://www.sparkfun.com/products/11524

The OLED screen can be one of two TWI addresses, depending on if one pin is low or high. So I might move to having two screens side by side as "eyeball" displays. Adding the mouth is a little harder unless I desolder things on one screen to turn it into an SPI interface.

Attached to the Side Mount Brackets that hold the screen channel on. Having the LED aimed downward at the floor and along the main channel makes it easier on the eyes, those 2812 are extremely bright.

Currently I'm running them colour syned to the wheel power. Low/no power = red color, high power = red+(g|b) depending on the side.

Normal nuts come loose fairly quickly, nylocks seem to be holding ok for that.
