Rotating monitor - Yet another take

I'll assume you read the Lazy Susan vs. Pizza Pan thread? This is a 12" bearing, and I thought it would be the one to beat; I was very wrong. It rotated terribly due to crappy bearing friction, plus had a lot of side to side play, which means one couldn't be assured a perfect rotation about a center pivot. I wanted to use the larger for the wire tunneling as well.
If you did read it, then good luck to you.. do let us know which bearing you are using and how it worked out. You will probably need to buy an expensive one, meant to handle a lot more weight then muffins (to steal the quote from someone else) lol

Good luck with your project southpaw13 :applaud:

Well, there are at least two different diagrams on this thread for a semiautomatic solution... (And a basic ON-ON switch is the best final option (the ON-OFF-ON version is great for fine tuning the system, though) I'd say.)
Going to build a "semiautomatic" rotation system? If so, the wiring diagram(s) should be enough. Really. If you're going to build a software controlled system I'd suggest ...well, more reading ..all the info is available on (or linked to in) the threads listed above.
And yes, do take pictures and document the project as soon as you actually start building it.
Have fun :cheers:

I have been taking pictures, but it is a little early to post. My motor won't come in until the 11th. I thought the on/off/on option would be a little better because it would actually send a stop signal to the motor instead of just full clockwise or counter clockwise. A small stop in between might extend the motor life. I actually want to have it working through software at some point once the plug-ins for Mala are working properly. I already got the lazy susan system operating pretty good right now. My success will be in the strength of the motor. I want to mount it to the top of the monitor and have the option of mounting a second motor to the botton if there is not enough torque.
Thoughts?

The Beta Program is stilll open if you want to PM me.. I haven't gotten any feedback from anyone yet so either they are still working on thier rigs (likely) or it just worked first time and no one felt a need to complain (unlikely)
If you are using the secret motor driver chip from Solarotics, you can run 2 motors off of it, not to exceed 600 MA. Mote amps than that and you need a different H-Bridge chip.. Da OLd Man posted one good to 20 Amps..

Welcome back Weishaupt,
I have been testing your program on the computer Im going to use for my mame machine, I have been experiencing some erratic behavior, but I probably dont have my config file set up right.
The job that pays me to be there has required that I be there, so I havent had much time to play around with it.
I was waiting until I can confirm what Im doing before I emailed you.
Actually, the H drive I built is the same as the one Koz319 did for his project, and the maximum on it is 5 amps.
(better make sure you use heatsinks on the power transistors if you push it that high).
Unless you are talking about my relay drive, it is good for as many amps as the relays you use are rated for.
Speed control is impossible for a relay drive though. (Or at least very impracticable.)
