A Harp Device for controlling an instrumented variable-friction mouse treadmill
Note
This repository contains design files for the electronics assembly. For the mechanical assembly, design files, and bill-of-materials, see the OnShape project.
- linear (no switching!) current control of 12V magnetic brake, Placid Industries B5ZD, datasheet.
- reads measurements from an RTS-10 torque transducer
- wheatstone bridge input for torque transducer
- quadrature encoder input for position/speed measurements
- Harp-protocol compliant over full-speed USB
- accepts Harp time synchronization input.
- reverse-polarity protected power supply.
This board design was created in partnership with the team at Second Order Effects.
