In this video I will show you how I tried to build a wireless video system for a drone but instead only ended up with a low power/range WiFi jammer. That means we will explore analog composite video, frequency modulation (FM), voltage controlled oscillators (VCOs) and much much more. Lots of experiments included ;-) Let's get started!
