Availability
This is planned as a small-batch hardware product from Norway. Built units aren’t shipping yet - pricing, batch size, shipping, and EEA compliance work are being settled first.
The whole project is open source. If you don’t want to wait for a built unit, you can build your own from the public repo right now - firmware, parts list, assembly docs, and the printable case files are all on GitHub.
Support the project
The whole project is open source - firmware, protocol, parts list, assembly docs, and the printable case CAD all live on GitHub. No paywall on any of it.
If this is useful to you, consider chipping in. Donations fund parts, testing, and the EEA compliance work needed before built units can ship.
