the way my hand contort, opposing muscle groups contract simultaneously, and it leaves them sore. I imagine the muscle groups get strong but it doesn't help much unless I can separate their behaviors somehow.

the bracket I connected it to is not on the motor. I can replace using the set screw.

i'm thinking on what fixed object I could mount the motor to. maybe I can lash it to a doorknob or something, maybe in a way that prevents it from flying around when activated.

I have some cord outdoors.
