Simracing hydraulic handbrake

This design makes it possible to connect a hydraulic handbrake to a computer, and use it as an analog input to most sim-racing games.

The files are designed specifically for [this](https://www.aliexpress.com/item/LZONE-RACING-Aluminum-Universal-Hydraulic-Handbrake-Lever-Drift-E-Brake-Racing-NEW-JR3654/32789759941.html) handbrake, but the concept can probably be adapted to most hydraulic handbrakes.

Turn the files upside-down before printing. The mount needs support, the other files do not.

In addition to the handbrake and 3d-printed files, you will need a standard 10Kohm potentiometer and an arduino pro micro. I also printed a [case](https://www.thingiverse.com/thing:320421) to mount the pro micro.

Use the standard arduino joystick.h library to program the pro micro as a game-input device. Connect the potentiometer to the analog-input configured in the arduino and mount the parts as pictured. When the handbrake is pulled the potentiometer will turn, and the arduino sends th
