Okay, the WiFi extender is on, the camera's on, they're both on the same network; we should be getting an image. All I see is a black screen. And my own reflection. I look sad. Maybe we should recalibrate it. All right. Step one: rapidly flip the calibration switch from the fully up to the fully down positions for at least ten times. It actually says "at least"? Yeah. Why would they say "at least"? Is it ten toggles? Is it 100 toggles? You know? Is it 1,000 toggles? Sheldon! You see where I'm going with this. Just flip the switch until the lights on the drone change to solid yellow. All right, that seems simple enough. Initiating calibration sequence. One, two, three, four, five, six, seven, eight, nine, ten. Well, I suppose ten is technically "at least ten. " But they're still getting at least one angry letter. Now I rotate it horizontally on its center axis until the lights turn green. Initiating rotation sequence. Don't look at me, initiate. Oh What does red and yellow mean? It means the calibration failed. We have to start over. Oh. Very well. Reinitiating calibration sequence. One, two, three, four, five, six, seven, eight, nine, ten eleven. It's a good thing I didn't send that letter.
