Pulsar is open source

The firmware, the perfboard build and the 3D files are public under GPL-3.0. Build one, improve one, or fold your changes back in.

Ways to contribute

  • Firmware

    Rust on the nRF52840 — the Maple bus driver, the Bluetooth LE gamepad profile, the VMU screen and the battery gauge.

    Help needed: Bug reports against real hardware, and the rumble path, which is wired but undriven.

    Report a firmware issue

  • Hardware

    The perfboard layout, the bill of materials and the pin mapping, for a hand build.

    Help needed: Notes from your own build, and part substitutions when something is hard to source.

    Share build notes

  • Enclosure and 3D

    The printed housing that closes over the board and cell, and the screws that fit it.

    Help needed: Prints on other machines and filaments, tolerance fixes, alternative shells — plus a shell that fits the rumble motor, and cleanup of the current design.

    Share print results

  • Testing and docs

    The part that needs no soldering iron: does it work on your console, your host, your OS?

    Help needed: Pairing reports from hosts we have not tried, and corrections to the build guide.

Pulsar exists because of work and help from other people. Some of it is theirs.
