Turning the Raspberry Pi Into an FM Transmitter
- stephengillie 14y agoHow long until someone's running TCP over this? It's just a matter of time until we can use this with a cantenna to control very-long range drones. Combine this with one of the winners of the Groupon DroneGames[1] and you could control a fleet of cheaply-made drones across a wide range. Is anyone interested in creating an autonomous fleet to patrol their property and airspace?

- lutusp 14y agoIt would have been nice to show the FM modulation equation in use along with the code. I say this because most people underestimate the complexity of FM modulation and instead write an approximation that doesn't create the hoped-for result. Here's a reference for the actual math: http://arachnoid.com/phase_locked_loop/index.html#Detailed_Description http://arachnoid.com/phase_locked_loop/index.html#Detailed_D...
