Tech Solar-powered FANET vario I built in my workshop in Slovenia — first ten are done
I fly out of Kobala takeoff (SI) and I also design small BLE instruments for free flight — firmware, PCB and app all done myself. This is the one I'm most attached to: a 29 g FANET beacon with a barometric vario that runs off a little solar panel, so there are no cables and nothing dies on you at launch. The idea was to add only what a phone can't do — long-range FANET radio and a real baro sensor — and let XCTrack/SeeYou/LK8000 do the rest.
It's a FANET beacon (you see nearby traffic and stay visible, and you can read where others are climbing) plus a vario with adjustable audio, configured over Bluetooth. I've only built ten so far, so this isn't a big launch — just curious what pilots here think of the approach, and happy to get into the FANET range, the solar/supercap side, whatever you want to dig into.
