(Starscream, Transformers Prime season 3, "Thirst")

Good news: Servos arrived early; I got 'em on Thursday, did a test on the Arduino with the "Sweep" program, they work fine.

Bad news: I forgot that micro servos aren't continuous. Now, I can modify them, but here's the real bad news: more parts have to be ordered. They each need two 2.2k ohm resistors, and instead of just buying those, I figured that I'm going to need all sorts of resistors at some point, so I just up and bought a full pack of resistors, which should be here on Thursday, as well. I don't regret getting the micro servos, though; the big, continuous servos are expensive, one of the main points of this project is affordability, and one of the main points of this contest is hacking. It's a win-win!
