What’s open source hardware?

Schematics PCB designs Firmware Software Parts lists and instructions

We give blanket permission for anyone to use, modify, or distribute everything

we do. No charge, no restrictions.

Real export license for a commercial autopilot that’s less capable (no IMU) than our LEGO autopilot:

“No engineering design, manufacturing information or detailed repair/maintenance procedures may be released.”

  “When not in use, the autopilot must be stored in

a locked, secure facility. There must be access provided to designated US government personnel. The secure facility must be monitored by CCTV and an electronic burglar alarm.”

“A daily inventory log of the autopilot’s location must be maintained.”
