A couple of nights ago my doorbell rang. It was after dark and I wasn’t expecting anyone. Before I could get five feet closer to the door the doorbell rang again. Someone was in a rush. When I opened the door it was two neighborhood kids, one about 8 years old and the other perhaps 6. He had one of those tiny mini-quads which, as you can see below, had some battery connectivity issues.
“Can you fix it mister?” the kid asked… I told him I could probably fix it, but it would take me a couple of days because I was busy. So he left his quad and went home.
After dinner I decided to to my best Scotty from Star Trek and fix the thing in a fraction of 1/1000th of the estimated time. “I can’t fix the warp engines for 2 days, but I can get you warp speed in 2 minutes.”
I looked closely at the circuit board and could see markings for + and – battery connections. I re-stripped the leads, soldered them on, and the bird powered up perfectly. The kid was blown away when I rang his doorbell some 30 minutes after he rang mine. He was thrilled to have his bird up and running again. His parents asked me if I would mind “teaching” him some stuff about drones.
