Rotating one motor using another manually?
Hello, I've came across the following videos recently:
https://www.youtube.com/watch?v=1zwboVgzugw (can watch from around 1:30), and this: https://www.youtube.com/watch?v=2qVNxvnkGug (its pretty long, around 7 minutes should somewhat describe it).
From what it looks like in the second video, he connects 2 motors plus to minus in opposite directions, and then when he manually moves one motor, the other moves as well.
I'd like to make something like that, but I just want to make sure before I do, am I missing something here? Is it really that simple? Just taking 2 motors, then connecting them plus to minus and it will work?
On another note, can someone explain about it? What is the name or principle behind this mechanism?
Thanks a lot!

It looks like two DC motors.
A DC motor and DC generator are basically the same thing. Apply power and it runs like a motor. Spin the shaft and the unit generates power.
Basically what he is doing is spinning one motor and it is acting like a generator generating power. That power makes the other unit act as motor and spin. Spin the opposite direction and the +/_ generator reverses and the motor runs opposite direction.

It would've been nice to get an answer as well, but I want to use it to control a telescope focuser without touching the telescope, and it looks like an awesome way to achieve that

No.... you'd want to use servomotors. They are small motor and gearbox combos. Designed just for what you want to do. In the link is just one example.
DC servo motors
You can search "small dc servo motors ebay".
They run on low DC voltage. You could use a spring loaded center off switch to reverse voltage to it for in and out motion.

Can you elaborate on the "spring loaded center off switch to reverse voltage to it for in and out motion.", and is that different than what showed in the videos?

Yeah, but I think it will be easier to use that way, so why not I guess ^^
