Field notes
Penon is described as an early-stage ultrasonic wind sensor mounted at a sailboat’s masthead, using no moving parts and accounting for the boat’s own motion. Tadorne says its releases combine schematics, PCB sources, OpenSCAD mechanics, firmware, and design documents under free licences. The practice also emphasizes auditable specifications, including error budgets, and signs releases with a GPG key anchored in DNSSEC.
