PyEtchASketch

Drawing pictures using an etch a sketch, motors and python.

Detailed writeup available here: https://sunnybala.com/pages/etch_a_sketch

I did the image analysis (EtchASketch.py) on my PC. It generates a path in the Paths/ folder. I then ran pictureDraw.py (which imports stepperMotor.py) on my raspberry pi to actually draw the images. You'll need to adjust these files to calibrate for your specific build.

A few sample images and their outputs are pre-populated. I used sigma parameters between .33 and 1.
