My dream would be to implement a bicycle dynamo (or rather universal) charger that negotiates the out voltage with a 2.7 to 40V buck boost (like the LTC3115-1 [1]) in the middle.

- zrail 3y agoKind of like this? https://pedalcell.com https://pedalcell.com
- perilunar 3y agoJFHC that's expensive — $641 for a tiny generator and a battery. That's more than my bike cost.
- morsch 3y agoIt's 399 USD. Still seems ridiculous.
- riedel 3y agoI already have this one (much cheaper, German site) :https://www.forumslader.de/forumslader-pro/ https://www.forumslader.de/forumslader-pro/ But I also successfully used a combination of simply a shortly rectifier, some Zehner diodes without any buffering via batteries. It would be great to have the buckboost just after the rectifier IMHO. I would somehow expect it to work much bette if one could simple pass down the higher voltage in USB-C if you are riding faster rather than converting it to 5V.
- perilunar 3y agoAh, I was getting AUD without realising it. The page converted the amounts without notifying. But yes, still way overpriced.
