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.

Features

  • Arduino Nano, Python and Tkinter based project.
  • Microvolt measurements using a commodity op-amp and no analog to digital converter with 16 bit resolution
  • Novel Tkinter based GUI with hierarchical presentation with network based message passing
  • Single bit control loops for brake current control
  • Control board uses extremely low power by using charge and dump techniques for controlling power switches
