1st project - rotating monitor - no name
DaOld Man:
Great work Haterot!
I was wondering if you have made any progress lately?
Haterot:
danny_galaga,
You would not believe how hard it is to find 1-2" fixed casters. but i agree i th ink there is an inertia problem with the rotating caster which may be causing the current motor problems.
Da OldMan,
Not to much, ran into trouble with the rotating motor. I was all ready to put the bezel in. but the monitor is not turning 100% and I have to fix that before I can get anything else done.
I did mount the MB and HD and cut out a slot for the power plug, ethernet and fan intake on the back
DaOld Man:
thats looking real good.
Wonder if you could replace the secret motor with a bigger one?
Maybe put a tire on it and mount it the same as the secret motor is?
Also, have you tried full speed to the motor?

What motor problems are you having? I had an almost exact same setup, and the motor struggled with the weight.. especially in the backwards direction. Why? Well, you mounted the motor at the bottom. Therefore, there the motor likely also helps support the circular disk due to the hanging angle. I ended up moving my motor to the top, and adding two support wheels made from fixed casters which the disk rested on.. instead of resting on the motor wheel. If I recall, DaOldMan has done exactly the same thing.
If these are not your issues, then never mind. I couldn't get that exact setup to work in my cab.

Haterot:
well 2 problems. it's either struggling to turn and the motor slips or it doesn't turn it at all (motor struggles) I inverted the monitor so the cables were at the top to give it a little top heavy. That helped some but not enough. I will try to move the motor/wheel to the top but I am thinking with the weight of the monitor/cables/mounting board is to much weight for a traction/friction wheel. That's why I was thinking of going with the chain method.
