Looking to do an exercise bicycle generator similar to what Forrest did in:http://endless-sphere.com/forums/viewtopic.php?f=41&t=30175
We got an old exercise bike that you can use both the pedals and the arm things.
I have some smaller motors in a box that I got from someone long ago. Looks like the MY1016-H will be the perfect motor for this project, this is pictured in the above pic.
The bike has a 2 stage reduction 45/14 and 45/18. (The two larger sprockets were pretty much totally covered, so it was hard to get an exact count, I might be off by 1 tooth.) and an early mod made a third reduction, but we are going to have to redo that, so I don't have numbers for that reduction yet. Actually, if someone can give a good number for that 3rd reduction, that would be cool. We are looking to do a 12v charge out of this setup. Spinning the motor with an electric drill set on 2 will full throttle gave about 8 volts coming out of it.
Our goal is to be able to jump on this and add extra electricity for days when the solar panels or windmill didn't get enough power through the day, or if there are some extra power needs. We want to have this set up for a big party in March where DJ Chill Will is going to be spinning using Off The Grid made power. We think it would be cool to have everyone at the party take turns and jump on the bike generator for a few to help keep the music going. With 50+ people there, this shouldn't be a problem at all. We do plan to have the power from the bike go into a battery bank.
Any thoughts, opinions, advise, etc. is greatly appreciated and encouraged.
