Another 3D printed working machine.

I have been working on this one for a while.
Hand cranked
Output - 5v dc
USB ready
Works good as a cell phone charger.

Wow, that is pretty darn cool! Do you have a video of this being used? Did you design it yourself? How much charge does it actually give your phone?

Thanks.
I don't have a video yet. The charge PCB outputs 5v dc and 3 amps maximum. The dynamo makes 0-30 volts with just the 3 phase rectifier attached. I still have a lot of testing to do to get all the performance data. If my wife would sit still long enough for me to charge her phone I would know more about how long it would take to make a difference on a phone battery. I did run it on her phone for about a minute or so and the phone battery causes a hefty drag on the dynamo so I assume it is doing a good job of charging. I will know more soon.

Cool, keep us post. It acuatally looks nice too :)

Finally got my USB voltage and amperage tester so I will have a video of it all up soon.

Heres a short video of the charger working. The output depends on the load up to 3 amps. The phone took 4.5-5 volts dc and .14 to .2 amps.
