Thanks for reading this post. Have you ever seen a bicycle generator? They are little flip down dynamos that spins as the bicycle wheel turns. Here's a link to a picture of one.
I am wanting something similiar to that in size. But I am not looking to light a light bulb, I am trying to get the square wave the rotating magnets (in the dynamo) produce. I thought if I had a high speed DC motor, I could use it in the same fashion but have the benefit of roller bearings because of the high speed it will be moving. I am not trying to reinvent the wheel, just use something that is out there. But I am having a helluva time finding it. :)
I could email you a drawing of what I am looking for in hopes that what I am saying will make better sense. Thank you for taking to read this Todd
