DIY One Wheel 

I added some final touches with the grape tape and then I began the testing phase. 

The board uses the same software as the original hoverboard just with the changes that it only uses one gyroscope sensor for the self-balncing and to control the motors. 

As with every engineering project things never work on the first try. During the first test, I had some calibration issues with the balancing. This was easily solved by recalibrating the gyroscopes. Then I was facing the problem that the tire was too flat and this didn't allow the wheel to rotate properly. This problem was a bit more complicated because the tire I was using was tubeless but since I wasn't able to get a proper seal with the 3D printed rim I had to use a tube but it wasn't meant for that exact tire size. So I had to 3D print some parts to help keep the tube in place inside of the tire so I could inflate it more without it shifting the weight of the wheel. The most challenging problem I had was that when I started going fast or on a steep uphill the board would suddenly shut off and throw me forward. This had to be a problem with the motherboard or the battery. So I replaced the motherboard twice and I also replaced the battery but the problem persisted. I later found out that the problem was that the battery's overdischarge protection was triggering and shutting off the battery's BMS. Since the two batteries I had tried were from old hoverboards they were not the best quality. To solve this problem I had to buy new batteries, which were a bit hard to get in Guatemala.
