Solar powered V8 desk toy

Hey, had an idea of making this "little/big" V8 a solar powered desktop toy.

First i thought about using this kit (solar panel + motor)

Then after I received i realized that it were a high revving motor with low torque. A reduction gear would increase the transmission loss then i moved to this one:

Since the solar panel only generates 1,1v @ 200mAh, its very low speed even in direct sunlight.

Yeah, direct sunlight and PLA in the same sentence... Not a good idea.

This video was made using 5v USB. It´s been raining a lot these days and i could not made a good video...
