Sequential USB shifter / Handbrake

!Check out Carlos' remix, it's an improved version you probably should download instead!

Summary

A shifter with a switch on the side so you can use it as a handbrake. The shaft mounts to a potentiometer on one side so you get accurate values. Keep in mind the travel can be a bit short for the handbrake, but I am using this mainly for the seq shifter and I figured it's better than using a plain old button. Keep that in mind if you're using this for a handbrake. But you can remix it and just remove the mounts for the switches to give it a lot more travel space.

If you need some changes and don't know how, just ask in the comments. I'll gladly help :)

I made space for an arduino in the base, but I ended up hot gluing it to the bottom of the shaft so it follows the movement. It seemed to work better.

Components needed:
2x - Micro switch
1x - Potentiometer
1x - Arduino pro micro
1x - USB cable
2x - Pull springs (5x25.5mm)
4x - M4x25 mounting screws for the sides
4x - M4x6 mounting screws for the base
4x - M4x6 for the springs
4x - M2x10-15 for the switches
4x - M4 for mounting the base to whatever surface you want
