An open-source joystick for people a conventional stick defeats. Contactless sensing, ordinary USB, and 3D printable, so a unit can be made locally instead of ordered through a dealer.

An Omega Stick drawn apart into its seven printed parts: the cap, the stick and its ball, the two socket halves that close around the ball, and the three plates below that carry the magnet, the sensor and the microcontroller.

MIT licensed, firmware and mechanical files both. Driverless on Windows, macOS, Linux, ChromeOS and Android, and on Xbox through the Adaptive Controller.

What is unusual about it

Low force is not the rare part. Open is.

Sub-10 gram sticks already ship, so low force alone is not unusual. What they have in common is that they are closed, mostly dealer-gated and often unpriced.

The unoccupied position is the combination: adjustable low force, an open design anyone can fork, plain USB, a price published rather than quoted on request, and a published method for measuring the force claim.

We are aware of no vendor here that publishes how it measures force. Where an independent measurement exists alongside a vendor figure, the two disagree.

  • Open from the first commitMIT-licensed firmware and published mechanical files, in a public repository.
  • A standard input deviceAn ordinary USB HID device. Nothing to install, and nothing for an IT policy to block.
  • Controller or mouseChosen on the computer and kept on the device, so the setting travels with it.
  • PrintableDesigned for local fabrication, so a unit can reach somebody no distribution channel serves.
The other half

An input you can reach is only half of it

A device you can operate is worth little if the software demands a chord of held buttons. ATDev works on both ends. Omega Stick is the input; OPAL, the OPen Accessibility Layer, opens the Unreal Editor to voice, gaze, head tracking and switches.

Separate projects, neither depending on the other. The stick is a standard USB device, so it works wherever a controller or a mouse does, the Unreal Editor included.
