my spinner hack using a mouse and a hard drive and a rubber band

<< < (5/6) > >>

facesmiths:
that is what it looks like to me as well but I would check closely in the center of the top and make sure there is not a torx (star shaped hex) or a hex (allen wrench type hole) cause it may be held to that as the part with the platters spinning on it has 2 bearings inside and the center of the bearing is fixed on the motor base while the inside of the spinner that the discs are on is where a magnet that has many poles (magnetic poles ns ns) radiating inward. I took the bearings from one and used it as a locking point by pinching them with the nuts on a piece of all thread. then I used a second center and removed one of the bearings so I could pinch only one of them from both sides thus not stopping it from spinning freely. let me draw up a couple renderings and I will post them in hopes they help explain this.

facesmiths:
sorry this is a duplicate post that had not had the pictures added and I can't seem to delete my own posts so it stays as this explanation.

facesmiths:

ok here are the pics basicly the first is just a bearing so you know the parts I am talking about (if you are color blind it might be hard so let me know and I can find another way)

first picture:
the blue part is the outside and the green is the cover over the little balls that do the smooth ride basically. the gray inner thing is the inner race and that is what the rod is actually going though

second picture:
the yellowish thing added here is supposed to be the threaded rod but it has no threads so pretend ok?

third picture:
here is shown the nuts on the all thread (remember to pretend it has threads and is not a smooth rod) pinching on the inner races (cant see them as they are under the nuts but they were gray remember?)

this way the rod moves smoothly.

if you leave space and pinch on the race from one bearing and another it creates friction on the balls in the bearings thus the two bearings become just a pair of washers. if you want to use both bearings you have to put something inbetweeen them that hits only that inner race and nothing else before pinching on them and then they will rotate smoothly. I would do this for stability as the knob wobbles a bit with only one except I am working on a differing design that has the encoder on the rod going into the knob and using bearings with a 5/16th inch inner hole so it will be much beefeir. also the encoders will be metal instead of plastic. I will update it and here when I get it working properly and have some pictures.

djcalle:

Thanks for the detailled answer.

I will try this tonight when  I get back from work.

They must have fixed that...once upon a time if you paused when setting your controls they wouldn't stay in place.  You had to do it with the game going.
