Assembly Notes:
* Pictures include key assembly steps, roughly in order.
* TFT gizmo should fit snuggly in rectangle in body; trim body if necessary.
* Fit of whole gizmo/circuit-express stack is tight in body.
* Main joints are designed to insert 90 degrees from operation (flat side of ball joint aligned with sides of slot) then be rotated for tight fit.
* Fingers have similar design, but probably work better to just press them into position in final orientation.

Software Instructions for animated eye:
* follow adafruit instructions for setting up circuit playground bluefruit for circuitpython https://learn.adafruit.com/adafruit-circuit-playground-bluefruit
* follow adafruit instructions for setting up circuit playground bluefruit for tft gizmo https://learn.adafruit.com/adafruit-tft-gizmo
* also need to add to lib: adafruit_display_shapes (install like
adfruit_display_text in instructions above)
* copy dingbot_eye_v9.py here to CIRCUITPY/code.py on your circuit playground bluefruit (looks like their most recent setup changes thing and _v7, _v8 won't work with it; _v9 updated 9/4/2020)

Animated eye operation on Circuitplayground
* slide switch center back (D7) controls if Dingbot blinks
* reset switch in center back to reset (maybe useful to wakeup after drain power on battery)

Instructions for printed eye:
* On Prusa, set to change print filament for pupil (white to black)
* use M600
* dingbot_nogizmo_eye.stl with Simplify3D and 0.2mm layers, I put before layer 42 out of 49 layers
* Eye pops into rectangle where TFT gizmo would otherwise go

To build from scad, you may want Write.scad:
* https://www.thingiverse.com/thing:16193
* dingbot_body.scad assumes in same directory with associated write directory
