DIY enthusiast crafts PC control system for Steam Deck using custom 3D-printed connectors, incorporating dual touchpads and split design reminiscent of the Nintendo Switch 2.
A tinkerer has constructed and assembled what he aptly dubs a homemade Steam Controller 2, or Steam Deck-inspired controller, as part of the OpenSteamDeckController project. This contraption also boasts the appeal of split, Nintendo JoyCon-like controllers, much like in the creator, TommyB's, recently shared venture.
The original Steam Controller was arguably before its time, but thanks to the success of the Steam Deck, its trackpad-centric control scheme is no longer an alien concept.
Disappointed by the lack of a similar design for PC gamers not fortunate enough to own a Deck, MakerTuber TommyB ventured into DIY territory for a remedy.
Before delving into the project, consider TommyB's caution - this project demands a substantial amount of off-the-shelf parts and may require some electrical know-how to successfully pull off. Nevertheless, fearless enthusiasts, arm yourselves with persistence and curiosity, because we wouldn't be surprised if many of you are still up for the challenge!
Tackling the Trickiest Half
The 'Steam Controller 2' construction began with the most challenging part: the trackpads. The process demanded thoughtful sourcing of multiple components from various outlets. A Steam Controller or Steam Deck trackpad assembly isn't available for purchase, and neither was TommyB keen on cannibalizing existing Valve hardware. The importance of trackpads in Steam Controller-style game interaction cannot be overstated.
TommyB's ingenious solution for the custom trackpads is based on the IQS7211E capacitive touch controller. To perfect the requisite capacitive touchpad design for this project, some effort in EasyEDA PCB, circuit design, and simulation software was needed. In addition, custom firmware was written to get everything functioning within the controller, which has been shared on GitHub for your perusal.
Moving on to the less daunting phase of the build, TommyB guides us through the off-the-shelf parts necessary to create the controller. Rest assured, no Steam Decks were harmed in the fabrication of this device - we already know the lengths TommyB went to craft his custom trackpads!
Stepping Up to the Challenge
Ready to take the journey in TommyB's footsteps? The OpenSteamDeckController GitHub page houses the necessary details, including the firmware, PCB details and schematics, as well as the .STL files for the pair of controller connectors. Essential resources for printing this design!
Even if you don't feel inclined to jump into this project now, you might reconsider once TommyB updates it with a cheaper new dev board (replacing the Adafruit), improved ergonomics, and more. So stay tuned to TommyB's channels for updates! If the official Steam Controller 2 and the desktop PC SteamOS release satisfy your needs for a comparable controller, though, this DIY endeavor may become redundant.
