Solar Guitar update (new vid) 7/20/05

More work accomplished this week! I added picks to 2 more of the pager motors so I have a total of 3 now. I think that is enough for a proof of concept protoype. The electrical tape on the ends of the picks is definitly the way to go. The solar engines just doesn't have enough kick to get the pick past the string. Also if I put a bigger capacitor (10000mf or bigger) in the engine and adjust the motor so the tape just barely nicks the string, the motor spins longer and creates a nice droney effect.

Here are the prototype motors with picks added. No E-tape yet...



I built a mockup of a the motor mount as well. It goes over the very last frets on the neck. This one is adjustable at all four corners, but I hope that the final mount will have individual motor adjustments. Since the "picks" will be hand made, they won't be exactly the same length which necessitates the individual adjustability. Right now the mount is attached to the guitar with velcro which makes for a very wobbly and imprecise mount.


Here is a shot of the motor mount on the guitar with the 3 motors on it.



Here is a short video of one of the motors firing. It is hooked up to a breadboarded 1381 solar engine.
