What is it?

It's... a generator. A permanent magnet axial-flux generator, with a 64:1 gearbox. As seen/assembled/demonstrated on YouTube, i.e. https://www.youtube.com/watch?v=9xJnymploEQ. Sold as a kit, i.e. you get the bits and pieces and have to follow the YouTube-video to assemble yours. Saves the bother trying to come up with the parts yourself. What you see in the images is what you get.

Please note: I make these to order. When the order goes in, I get workin'. There may be a bit of lead-time, but I'll eager with the communication all the while.

You can wrestle it up to 12v. Be mindful, it's 3d printed. The gears will stand up for themselves, but not for punishment. Look at it like a science experiment, not a production asset.

Why did you make it?

It's a generator - you can make your own electricity! Electro-magnetism is wonderous, and to be able to yield the power... Oh boy.

What makes it special?

It comes with an awesome YouTube-tutorial with all you need to know about how it works and how to put it together; https://www.youtube.com/watch?v=9xJnymploEQ
