Traditional joysticks typically use potentiometers or hall effect sensors to determine the displacement of the stick itself when moved by the operator. Force-sensing joysticks are considered more desirable for certain purposes like side-stick flight simulators, because they measure the force applied instead, as per the name. They can be expensive to buy off-the-shelf, but you can build a cheap set on your own if you know what you’re doing, as [tekasza] demonstrates.

The build that [tekasza] put together is based around the Teensy 4.0 microcontroller. It’s set up to read a series of load cells that determine the force applied to the stick in the X and Y axes. The cells are wired up to HX711 load cell amplifiers so they can be easily read by the microcontroller. The Teensy does the work to take the load cell readings and convert them into axis outputs for a USB HID game controller, allowing the stick to be used with just about any game or simulator on the market. [tekasza] has the stick integrated with pedals as well as a whole bunch of buttons and switches to control other simulator features, built up into a full seated sim setup.

If you’ve ever wanted to use a force-sensitive stick like modern fighter pilots do, this build could be very relevant to your interests. We’ve also seen plenty of other great sim hardware builds in recent years, too.

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 than to keep adding capabilities to some of the sim rigs we’ve seen. 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. Even then a 3D printer is not always necessary, like this three-pedal setup using extruded aluminum frame as a base. From there, all kinds of other features can be added like force feedback on the steering wheel.
