DIY Steam Deck Shell Transformed Into Split PC Controller With Touchpads
▼ Summary
– A modder named TommyB created a DIY Steam Controller 2 inspired by the Steam Deck, featuring splittable JoyCon-like designs.
– The original Steam Controller’s trackpad-heavy design is now more accepted due to the Steam Deck’s success.
– TommyB developed custom trackpads using the IQS7211E capacitive touch controller, requiring PCB design and custom firmware.
– The controller uses off-the-shelf parts, Hall Effect sensors, and repurposed Steam Deck shells, with no Valve hardware harmed.
– Project files, including firmware, PCB schematics, and 3D printer files, are available on GitHub, with future updates planned for improvements.
A creative modder has built a fully functional split controller inspired by the Steam Deck’s design, offering PC gamers an innovative alternative to traditional gamepads. Electrical engineer TommyB recently unveiled his OpenSteamDeckController project, combining the precision of Valve’s trackpad controls with the versatility of Nintendo’s Joy-Con-style split design.
The original Steam Controller introduced a unique control scheme that initially divided opinions, but the Steam Deck’s success has since proven the value of touchpad-based input. Frustrated by the lack of a modern equivalent for PC players, TommyB took matters into his own hands, crafting a custom-built controller that avoids cannibalizing existing hardware.
Before diving into the project, TommyB issued a fair warning, this isn’t a simple weekend build. It requires numerous off-the-shelf components and significant technical expertise. Still, for dedicated tinkerers, the results could be well worth the effort.
The biggest challenge was replicating the high-performance trackpads found in Valve’s devices. Since standalone replacements aren’t available, TommyB designed his own solution using the IQS7211E capacitive touch controller. This involved PCB design in EasyEDA, firmware development, and extensive testing to ensure smooth functionality. The finalized firmware and schematics are now available on GitHub for others to explore.
Once the trackpads were sorted, the rest of the build became more straightforward. The controller uses third-party Steam Deck shells, available in various colors, and incorporates Hall Effect joysticks, a premium feature that reduces drift and improves durability.
For those eager to replicate the project, TommyB has shared detailed resources, including 3D-printable connector files and PCB layouts. While some components, like the wireless dongle design, are still pending release, future updates promise refinements such as a more affordable development board and ergonomic improvements.
Though this DIY approach may not suit everyone, it highlights the demand for a modern Steam Controller successor. Whether Valve answers that call remains to be seen, but in the meantime, projects like TommyB’s keep the spirit of innovation alive.
