How to fix a servo

Pay $30 for 4 new servos & the old one will start working again.

Anyways, reflowed the QFN's solder joints, & made a servo exerciser to thrash it all night. Naturally, it would never fail on the bench, but the new servos alone stood a good chance of reviving it. The last order of standard servos was 2001. They were $6 Tower Hobby branded, but shipping was much lower. Those hobbyking servos are now $5, but shipping has followed inflation.

Signs started pointing to a glitching battery connector crashing the microcontroller on the servo. The mane CPU also had glitches, but didn't lock up. The servo may just lock up under certain power glitches. After a cleaning, the $60 servo was revived & didn't crash again. So it's a lot more sensitive to electrical noise than a brushed servo. It must run at a much higher clockspeed.
