"You can turn anything into an air mouse if you're brave enough"
— Piper, a.k.a. Pez
Naturally, the quote above applies to Flipper as well.
The app allows you to turn your Flipper into a USB or Bluetooth air mouse (you do need an extra module, see the Hardware section below)...
Using it is really simple:
- Connect the Flipper via a USB cable and pick
USB, or pickBluetoothand pair it with your PC; - Hold the Flipper in your hand with the buttons pointing towards the screen;
- Wave your Flipper like you don't care to move the cursor;
- Up button for Left mouse click;
- Down button for Right mouse click;
- Center button for Middle mouse click;
- Left and Right buttons for scrolling;
- Use calibration menu option if you notice significant drift (place your Flipper onto a level surface, make sure it doesn't move, run this option, wait 2 seconds, done).
See early prototype in action.
The custom module is using Bosch BMI160 accelerometer/gyroscope chip connected via I2C.
Take a look into the schematic folder for Gerber, BOM and CPL files, so you can order directly from JLCPCB.

Reality:
The code is based on the original Bosch driver and an orientation tracking implementation from the Google Cardboard project
TL;DR: Use the code however you want, give credit where it's due, no warranty of any kind is provided.
