Rotating monitor construction *Project finished*
weisshaupt:
Congrats on getting this finished. Looks great!
Did loadman write a new program that made it more customizable, or is it the same one you had before?
csa3d:
There you go! Good work on that! Good use of those bearings as well. Some questions:
1. Can you elaborate a bit more about the chain/sprocket combo? How did you mount the chain to the side of the disk? Where does one acquire these chains and sprockets? Probably a bit much for a hobby motor, eh?
2. I see you went with the MDF wheel. Decided that the pressure from the bearings wouldn't indent the unit?
3. Any chance of getting a YouTube vid posted :D
Thanks!

Thanks Weisshaupt.
Sorry for the late reply, I just got back from Cancun Mexico, and yes, the weather was perfect..
Loadman made a plugin for Mala that will call the program I made.
It passes a 0 or a 90 with the run command, based on which way the game needs the monitor turned.
I wrote the program called mrotate.exe.
I plan to use this program with other front ends too, such as Glaunch (a man never forgets his first love, right?)
I plan to write an interface program for glaunch.
My program has a GUI which the user can choose inputs and outputs, also time limits, and braking control.
Also I have started on assigning up to two outputs as lights, in case anyone wants to turn on an led while the monitor is rotating. You can also choose which action the light will take, such as blink or on steady..
I got a couple of bugs that need to be worked out, maybe now that Im back home I can pick up where I left off on it.

Thanks CSA, that means a lot to me..
Sorry about the late reply. (see above reply to Weisshaupt.)
1. The chain is a number 25, which I bought off allelectronics.com.
I think it is 2 foot length.
I attached it to the edge of the mdf disk with a screw in each end of the chain.
I also put two small screws on either side about halfway up the chain. These keep it from sliding off the edge of the mdf.
This was someone else's idea, I really need to go back in the posts and give proper credit.
The sprocket I also got from allelectronics. It is a #25 (cant remember the number of teeth.)
It is nylon. This might be a bad thing. While I was setting it all up, the mdf disk got caught on something and the sprocket slipped on the chain for a few seconds until I could get to the power switch. This wore the teeth down some. I think I will try to see if I can find a metal sprocket.
2. Yes I used MDF and roller skate bearings. I coated the perimeter (edge) of the MDF disk with CPVC glue. It dried to a very hard finish. Im not sure how it will wear over time, but so far no visible signs of denting at all.
3. I have never posted anything to You Tube, but I will see what I can do.
I had to carve up Benny B's Arcade some to get the unit to fit, so Im kinda ashamed to show it right now, but I may anyway, if I can figure out how to do it.
Here is a previously posted picture of the chain. Maybe you can blow it up and see more how I did it. I will try to get better pics later..
