PROCESS
I bought a tin container from the container store. After meticulously taking exact dimensions of the container I built it in Rhino and started designing my components around it. I also started out by making block diagrams of the hardware viz. Arduino MKR Zero, a rotary encoder and a 2-Axis joystick.
