Fan Stand Final

Fan Stand Final

I finally got a video of a working fan stand

The up and down is geared 1:5 with two motors power it. The turning motor it not geared.

D-Pad control

This program lets me control the robot using the D-pad. Left and right to turn the fan and up and down to move the whole thing up and down.

Analog control

This program lets you control the robot using the analog stick which make’s variable speed possible. left and right to turn the fan and up and down to move the whole thing up and down

Automatic

This acts like an oscillating fan. It resets everything to about the center and then you set the up and down positioned using the D-Pad and then it automatically has the fan go left to right. My only problem with this is that it went to fast. I could not make it go any slower because putting any less power just had the motor not move or stop halfway. I had the power on 10%

Fan Stand Update

Fan Stand Update

I got a working fan stand……but the fan died. So I will post a video and full description soon, hopefully I can find a working fan soon.

Whoops-Just realized that  the photos are squished (should be 16:9 but WordPress thinks they’re 4:3)

Fan stand version 2

Fan stand version 2

Same problem aslast time of brake not being strong enough, but this time I tried having the motors not move like before so that the motors would only be moving 1 motor and not 3. Apparently I’m going to have to gear this. Once I get a working version I will post a video.

Fan stand version 1

Fan stand version 1

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.
