Not really, but I need one for 6V batteries with a load and a dummy load. Can't seem to find wind ones for 6v.

No, seriously, is there a scale or something I could use?

Very good and round... unfortunately, the angle reminded me of this. I deeply apologize for this behaviour.

I think I have to figure out a realistic riding rpm, then compare my speed and rim circumference to the size of whatever wheel I plan to put on the shaft of the generator to find a motor with similar operational RPM, Current, and Voltage first.

I have no clue what generator to use. A brushless motor would be better, and I imagine the voltage would be somewhere around 6V-12V or a little higher, depending on riding speed.

I want to power my little Raspberry Pi computer and lights with a rechargeable battery that is charged by a dynamo attached to my bicycle wheel. Based on the stuff I have, it needs to be a 6V system. Charge voltage would be 7.2V and current 1.5A max, then outputs 5V 3-5A max through USB or USB-C.

I once again will have to build it all myself. Unfortunately, I'm not that good at electronics, so lots of research is in my near future.

Looking at an LM317 for charging and a MIC29501 for the USB conversion. I have other parts, but I don't know what MOSFETs to use or if I even need a relay.

Hmm... Caribou. Thank you for blessing me with this.

I would get a little plushy of him and keep him by my bed. I'd protect him with my life and commit various crimes for him.

Also, I should be drawn as him, just saying.
