The Hand Cranked Power Generator by EvenErichsen Sep 3, 2013

Description

This is a working power generator.

The rotor spins upwards to 4000rpms and produces about 40 volts, with no load.

It generates close to 15 watts...

Instructions will follow later..

Use the attached 3D Studio Max-file to see finished assembly for now.

I sure would love to see a bicycle chain variation on this.
When will you be uploading instructions or a BOM? Would like to build one without having to guess the screws and bolts used, and it would be helpful to know what electronics you used instead of just wiring something up myself. (Also you wouldn't happen to have a different file format for the model besides .max would you? Something I could open in Inventor or NX just to see it from different angles.)
15 watts is nothing to sneeze at. I'm impressed you managed it without just using a DC motor.

This design was optimized for the Replicator 1 printer.
But any printer with bigger platform can print this without editing.

Adding a coil spring to this would be cool. Wind it up and let it generate power while you do other stuff.
Very cool idea :) it has inspired me to build a similar version from scratch, may be with 5v output for USB, or other electronic devices... So maybe you could share some of your spec. magnet size, electric circuits and so on.
Keep up the good work :)
You should do the math on how long you will have to spin it to generate the power to build a second one. :)
Hi, and thanks for that!
I spent some time on the design, yes!

And its about a week of printing..
I will upload a video soon ;)
This should be featured!
Awsome device. Would love a video of it spinning.
Wow, great work, lots of time in that...well done...;)
need a couple of hamster wheels, so they can generate more than giggles.
