Live Aircraft Radar Display

A desktop/mobile app that transforms an affordable ESP32 display into a real-time sonar-style plane radar showing ADS-B aircraft around your location. Perfect for aviation enthusiasts, flight watchers, and hobbyists who want live flight tracking without expensive hardware.

ADS-B receiver hardware has gotten cheap enough that the hobbyist aviation-tracking community has grown substantially — FlightAware and FlightRadar24 have millions of users, and a meaningful slice of them want local, offline-capable hardware displays rather than just a phone app. FlightRadar24 is the obvious substitute, but it's cloud-dependent and not oriented around physical display builds, which leaves room for a niche hardware-software bundle. The $500–2k/mo revenue band is plausible only through one-time sales or small recurring fees to a tight enthusiast audience, but the ceiling is real — this is a hobbyist toy, not a professional tool, so upsell paths are limited and customer acquisition costs relative to lifetime value will compress margins fast. The biggest risk is that the audience is technical enough to build this themselves with open-source tools like dump1090 and a $25 RTL-SDR dongle, meaning the people most likely to want it are also the least likely to pay for it.
