Flying and driving simulators can go as far as money will take you, and at some point it might end up being cheaper to buy a plane or race car …. Two-Component H-shifter for Racing Sims. But it can also be a fairly affordable hobby as well, with entry-level components being within reach for many.
The price can drop precipitously from there too, provided some parts can be sourced and a 3D printer is made available, and [Jason] is demonstrating one of the lowest-cost H-shifters we’ve seen which only uses two parts at its core. 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. Although this was just a prototype, it shows was just a few off-the-shelf components and a 3D printer can provide to an affordable driving sim setup.
