TorqueTuner: A self contained module for designing rotaryhaptic force feedback for digital musical instruments.

TorqueTuner is an embedded module that allows Digital Musical Instrument (DMI) designers to map sensors to parameters of haptic effects and dynamically modify rotary force feedback in real-time. It comes with an embedded collection of haptic effects, and a is wireless bi-directional interface through libmapper.

Demonstration Video

The hardware is based on the ESP32 microcontroller and the moteus platform, to implement a force feedback rotary encoder with 3600 PPR ~= 0.1 degree resolution that can display forces up to 45 Ncm (63.7oz.in).
