Elliptical_Controller

Hardware and software control of a self powered elliptical machine using an Arduino Nano. Tkinter is used both as a GUI and as a multithreading environment.
Programming model is an industrial network with autonomous workcells communicating with each other. Each workcell is instantiated anonymously, maintains its own state and is completely private.
Message passing between workcells is done over a virtual network.
All control loops are single bit with 16 bit resolution without using analog to digital converters. Resolution is under 3 uV using only commodity CMOS op-amps.
Power supplies are controlled by switching regulators without inductors while still being efficient with very simple circuit topologies.
