Update on my research project that involved my bike

It's been mooonths since I posted about this, so for context, the final year of high school for us requires that we have a research paper with a physical output of sorts. In my group, my idea got chosen which was to use a gear multiplier to run an alternator to power a battery as an alternative source of electricity.

So it worked, once, then never again, but it was enough to pass. The gears had problems keeping the chains in place and the gears themselves had problems staying attached, while all those were present, the left pole for the rack could not hold the weight of the box and the torque needed to run the alternator, we remedied it with a piece of wood that was long enough to stand on the axle of the wheel and support the rack.

It worked, pedaling was really heavy, not a pleasant ride at all, this was not pleasant for the bike either. Took my time to post this update because I felt disappointed with how it turned out, but well, we passed, so it, was just ok.

The bike is free from the contraption now, and so am I from high school. However badly this was executed, it was good enough to get me to graduate.
