The most important part of our Servo Word Clock are of course the servo motors. For our previous clock we used SG90 nylon gear servos. Although they were labeled with the popular brand Tower Pro they were obviously cheaper Chinese knock-offs. For the new version of our clock we decided to switch to the more robust metal gear servos MG90S. To keep the price low original Tower Pro servos are still not an option but we ordered some servos from the Chinese brand MiToot. This should at least allow us to get consistent quality in contrast to ordering unbranded servos.
The servos we ordered were delivered very quickly and I let them running for a few hours without any of them failing. While this does certainly not count as a thorough lifetime test we felt confident enough to order 120 pcs that will be used to build the next Servo Word Clock prototype.
