Bicycle Generator
« on: April 21, 2010, 16:30:22 pm »
I have this thing to use a normal bicycle as a exercise bike. it uses a magnet on a wheel close to a aluminum disk in order to create resistance so the wheel does not run freely. What a waste of energy....

So I decided to built a bike generator so I can exercise and help charge my home UPS batteries.

Will be posting the progress here.

I was looking at whimhurst machines on youtube yesterday, and they have a small hand crank, and i was thinking it would be pretty cool to have a big pedal powered one, what do you think of that? some of them can make 4 inch sparks or more, would be pretty cool.

Alright, I now have all 72 3/4 inch magnets.

Drilled and threaded all 72 holes on the bike wheel.

built 2 frames to mount coils, one is for a single pick up coil, the other is for 12 coils.

I want to test using a regular laminated transformer, by cutting open one end so I get and E shape.

so then each of the 3 legs of the E transformer is aligned with each magnet on the wheel.

Do any of you have an old laminated transformer 2 3/4 inchs ?

Just mounted all 72 magnets,

built 2 coils using 2 old laminated transformers ( a little smaller than what I wanted 1 3/4 inch.) but getting 100 watts.

I'm liking this... going to make one more coil, since I just found one more transformer.

this will make you appreciate what a 100 watt light bulb uses for energy :P

you should see if you can generate up to 746 watts, or 1 hp, that would be a neat acomplishment, then you can say you are as powerful as a horse!
