DIY Steam Controller Puck Offers Xbox, Switch, PlayStation Emulation Modes
Valve recently released a new version of the Steam Controller that includes a wired USB puck, which acts as both a charger and a low-latency wireless receiver. However, these pucks aren't available for standalone purchase, which is where the OpenPuck project by [safijari] comes in. This DIY project utilizes the Pro Micro NRF52840 board to replicate the puck's wireless receiver functionality, allowing users to connect their Steam Controllers just like they would with the official puck.
Building a Better CNC Hot Wire Foam Cutter
