hub dynamo -> full wave bridge rectifier -> 60 LEDs -> glorious light

So it works. Finally, some kind of vindication that proves (at least partially) that a hub dynamo can power the LEDs. Yes, the resistance was enormous and you would most definitely not want that to be dragging you down, but keep in mind we’re only using 38 of those LEDs. Which may be a big difference.

We just need to add some smoothing capacitors and tuning capacitors and we can keep pedaling forwards.
