elliptical controller online with Winfy

We have hosted the application elliptical controller in order to run this application in our online workstations with Wine or directly.

Quick description about elliptical controller:

Project to use a Nano Arduino to control a self powered elliptical machine through a USB interface. The output of the three phase elliptical generator is rectified and regulated and then controlled by PWM and a PID loop to source a constant current to the elliptical brake. Generator pulses are counted to determine speed and distance.
Brake current can be set through a GUI which also displays exercise time, average speed and distance.
Tkinter is used both as a GUI and thread manager to simplify the software. KiCad is used for designing the printed circuit board.
A novel chopper model using AC detection with a random chopper signal is used to improve brake current sensing. This model uses a cheap commodity op-amp with minimal hardware and simple software and outperforms conventional DC based chopper circuits.

Features:

• Arduino Nano, Python and Tkinter based project.
• Hardware uses novel and simple lock in amplifier design for precision brake current control.
• Workcell message passing using two event loops for simpler asychronous programming model
