    Firmware, hardware files, and guides live on GitHub. Fork it, hack it, repair it — it's yours.

  • Designed in Oregon

    Every device is designed, tested, and packed by a one-man shop — not a white-label factory.

  • Support from the builder

Welcome!

Hello and welcome to my shop! My name is Daniel and I'm a former U.S. Air Force Nuclear Missile Operator turned electronics enthusiast.

I have been designing and manufacturing devices since 2016 and hope to share them with you. Please check out our GitHub page below to view all open-source projects.

Please consider supporting this shop because I've spent (and continue to spend) thousands of hours designing the devices, writing firmware, and offering support. Thanks!
