But it can also be a fairly affordable hobby as well, with entry-level components being within reach for many.
The two components only cover the electronics for the build, but this gets almost everything needed for the shifter squared away.
A joystick like those found inside many game controllers is paired with an Arduino Pro Micro, with a very straightforward wiring configuration between them.
These components are paired with a prototype 3D printed case and shift knob which provides the H pattern of choice.
From there it’s as simple as uploading some readily-available firmware, which [Jason] also demonstrates, and which has many options for various configurations of shifters.
