Yes Espy.... though I should show you my senior project plans. Prosthetic finger with a mini solar panel in the nail and uses electrical impulses too move (curl and place tension on a pulley)
The one for my engineering group. I think the plans are still drafted out on my computer.... I made one out of plastic with a rubber band and a battery added in behind the panel. but i never made the finger covering..
....We should make a robot together >.> I could do the mechanical/design aspects, you could wire it. I can't do electrical/programming stuff to save my life.
I did most of it for fun... I like wiring.. it was my favorite part... and programming wasn't too horrible it was a basic open close circuit with a really low trip voltage..
Babe.. I did most of it my Junior year.. And then it got scrapped by ISTA.. Why you never saw it.... Walters was impressed though.
