Solar powered V8 desk toy

thingiverse

I had an idea to make this "little/big" V8 solar powered desktop toy come alive. First, I thought of using this kit (solar panel + motor) found on Aliexpress. The solar panel kit looked promising, but after receiving it, I realized the motor was a high revving one with low torque, which meant that a reduction gear would increase transmission loss even more. So, I moved to another option - a worm gear motor with a long shaft and low speed, available on Aliexpress in Portuguese. The solar panel only generates 1.1 volts at 200 milliampere-hours, resulting in very low speed even in direct sunlight. Yeah, direct sunlight and PLA printing don't mix well together. Unfortunately, it's been raining a lot lately, and I couldn't make a good video to showcase the toy as planned.
