Hey everyone! I've seen videos where people convert fitness bikes into generators, and I'm curious if I can do something similar with my Sunny Health and Fitness mini stepper. I'm not very knowledgeable about electronics, so I'm hoping someone could guide me through the process. I don't have much experience with tools or the concepts involved, but I'm considering looking for 3D models online to help me out. Any tips or advice would be greatly appreciated!

I have some background in this area, and one idea could be to replace the stepper's pistons with neodymium magnets and use the cylinders to wind wire for generating power. Or you could even create a flywheel system to aid in spinning a motor for electricity. It's an ambitious project, but if you’re up for the challenge, it could be really interesting!
Honestly, your mini stepper isn't the best choice for generating electricity. You'll need to convert the up-and-down motion into a radial motion to effectively spin a small generator, which is a lot easier with something like a stationary bike that has moving parts designed for it.
If you're looking to save on your electric bill, it might not be worth the effort. The time and money you’d spend on tools and modifications could exceed any savings. But hey, if it sounds like a fun project, go for it! Just keep us posted on what you come up with.

That sounds really complex! Do you think it's doable for someone who isn't very experienced with electronics like me?
