Alright, I'll start with what im using it for.
For my culminating project in my computer engineering class, I got the old anemometer off the roof of the school and decided to digitize the signal so it could be read by the newer computers. What I did is I opened the housing where the magnet and the coil used to be and am now using a stepper motor as a switch. Everything works great except for this one thing that has stumped the teacher and myself for a couple days now .
When I take the stepper motor and turn the shaft with my fingers, it generates the signal perfectly, showing up on the led display. Now, here's the issue, when I put the 3-cup wind catcher onto the stepper motor and spin it, I get nothing.I have made completely sure that the wind catcher is indeed spinning the shaft and everything is wired exactly the same as when I spin the shaft with my hand. I have tried different motors all to the same affect, I have also tried spinning the shaft with my hand while touching the shaft to the 3-cup catcher to rule out the possibility of the metal doing something to it. I am completely stumped here guys, I can't see any reason at all why it won't work, but maybey I'm just ignorant of the situation. Hopefully you can help me out, many thanks.
