HElp! My electronics education ended with my 7th grade electronics kit-but I was SURE this was within my abilities!!
I built a spin art machine for my kids and the AA battery keeps getting redhot with use.
I have a DC motor originally powered by 8 AA cells, a toggle switch and one AA battery powering it now, all wire with CAT 5 stranded wire.
The motor spins a 4"x6" piece of 1/8 inch plywood which paint is dropped onto, making a swirl or starburst design.
After a few minutes, the battery is almost too hot to hold. I think that as a motor spins, a current is generated and sent back toward the power source. Is that correct, is that the problem, and more importantly how do I fix it?
Thanks for your input- I have six little hands with paint bottles ready to squirt any second!!!- Shawn
