The whole FPV (First Person View) R/C flying hobby fascinates me. I’d love to try it at some point. This system, being developed by a French maker, is a board that plugs into the video camera system used in a FPV rig to provide a heads-up display with useful flight, navigation, and power information. Looks like it’s still in the prototyping phase and there’s no word about selling it, kits, open sourcing, etc.
Check out some of the other cool projects on his site, like this analog instrument panel to go in the cockpit of an FPV plane so you can see the instruments from the camera POV as if you were in the cockpit.
