Building AR Mario Kart for Real Mountains (With Raspberry Pi Prototype)

Author here. I've been prototyping with a modified snowboard helmet + Raspberry Pi + IMU sensors to map routes down mountains in Santa Fe.

The idea: groups of 4 race down custom lines with AR displays showing mini-maps, waypoints, live positions, and trick multipliers.

Inspired by Anduril's Eagle Eye release, but for sports we actually play. Think Strava meets Mario Kart on real slopes.

Technical challenges I'm working through:

Low-latency multiplayer on mountains (spotty connectivity)

Wide FOV display integration into helmet form factor

Motion detection for tricks (distinguishing backflips from bad falls)

Safety systems (speed governors, designated zones)

Just moved to SF and looking to build a working prototype this winter. Tahoe is 3 hours away for testing.

Happy to discuss the technical stack or answer questions about the safety/resort partnership angle.
