Open hardware
Projects that release physical designs under an open hardware licence. This is the hardest class of open medicine to build and the most consequential: software can be copied at no cost, but a scanner or a cytometer has to be manufactured before it helps anyone.

Nobody adopts CERN-OHL by accident. It exists specifically to cover schematics, board layouts, and mechanical designs, so choosing it is a statement that there is real hardware behind the repository. That makes it a better filter than any keyword: it selects for intent rather than vocabulary.
It also exposed a flaw of ours. GitHub’s licence detector does not recognise CERN-OHL, TAPR-OHL or Solderpad, so every one of these projects reports NOASSERTION through its API. Our importer treated that as unlicensed and skipped it — which meant we were systematically excluding the exact class of project this page is about. These records have their licences read from the LICENSE file instead.

545 records in the registry have no code repository at all. They are Zenodo depositions, HardwareX papers, and documentation sites — and they include some of the most significant work in the field. OSI² ONE, an open low-field MRI scanner, publishes on GitLab and its own site and would never appear in a GitHub search.
If you know of open hardware missing here, that is the most useful thing you can tell us — a whole class of projects we cannot see matters more than any single row. Open an issue.
