I built this fan stand that works with this old computer fan but this version did not work; it could turn fine but had a lot of trouble with the up and down. It had trouble going up and down so the speed had to be 80 at times but the problem is once it gets halfway it would shoot down. The other problem was that it wouldn’t stay up. No matter what I did I could not get it to stop, the brake just wasn’t strong enough to stop it. So what I plan to do is connect the motors to the NXT and then have the top motor move only and see how that works.
Whoops-Just realized that the photos are squished (should be 16:9 but WordPress thinks they’re 4:3)
