When I first met this little device, I liked it immediately. I decided to make my own POV. I watched lot of videos, and recognised some main problems. The power supplying of the micro-controller was the biggest. Spinning battery or sliding commutators were both refused. Only option was the air core coil for me. That solution seemed too difficult. I could manage to solve this problem successfully. I created an easy but relatively efficient circuit with a few electronic parts.”
