Rotating monitor - Yet another take
csa3d:
Nice, gonna order some parts today to get the ball rolling over my way. Questions:
1. Did you upgrade to the "Regular Motor 2" from solobarics as suggested by the wiki link you provided or did you stick with the default one that comes with the GM3?
2. Are you running this off of 5v from the cpu power supply? Did you need any other parts to regulate voltages?
3. Did you upgrade the rubber wheel like suggested in the wiki?
4. Are you planning to have a vertical mounted screen in the end?
Links to products mentioned above, for others (can you confirm parts?):
Gear Motor 3
Friction Wheel
Regular Motor 2 upgrade for GM3
Mucho Gracias!

When I was working on this, I did get it working with the standard GM3 motor. It just seemded to be working too hard for me, so I upgraded. I also had it working with the standard tire, but then upgrade to the extra grip tire. Its better, but I don't know if its required. (my original mechanism uses a pizza pie plate spraypainted with plasti-grip so the friction may be harder to achieve than when using wood)
My setup runns off of 5 v power from the PC, but its buffered via the Secret Modem Driver- which, among other things, provides diodes to prevent EMF from the motor from being sent back to the power supply and/or logic leads. If you wanted to isolate it, you could just get a 5 V wall wart from Radio Shack and use that to provide the power.

Back again.
weisshaupt, yes the parts are almost the same, for obvious reasons ;) Thank you so very much for all the info :cheers: I don't know about the lazy susan as the wheel bearing works great as it is ..maybe with another build. And I haven't even started with this really, oh well ::)
About the friction and angled use: I might yet have to fine tune the friction (maybe lose the small wheels, reduce - almost eliminate - friction) we'll see, someday.
I left the main axle (unnecessarily) long just to be able to mod the system if needed with a bicycle chain solution.. So far haven't found suitable sprockets and so have yet to figure out the actual attachment too. Was actually thinking about using two sprockets: a small one on the motor and the biggest I can find attached to the main axle under the monitor mount.. So, if and when you figure out a durable sprocket-wheel to GM2/GM3 mounting solution, please do remember to document it !!
csa3d,
1. I'm using the stock GM3 motor ..but bought one RM2 "just in case". No need for it at the moment
2. Since I haven't even started on the main cab I'm at the moment running it from a regulated variable V wall wart. Can't get 5V out of it, but have tested with 3V, 4.5V and 6V - 4.5V seems just about (almost) right.. A bit of laboring going "up" with all cables hanging from the monitor.. I'm sure 5V will be just what the doctor ordered. The final power source ..?
3. I'm using the basic GM Series Plastic Wheel with no upgrades. The wheel works fine on unpainted MDF surface. I had to add a few drops of super glue to it as it seemed to me that the silicon tires might not stay in place on the rim..
4. Monitor will be angled ..See the attached videos: +/- 15 degrees to that... ave to design a cabinet first.. ;)
So.
First real world test with all the cables hanging from the monitor.
The monitor mount is sideways (shouldn't really affect anything?).
All test were done at 4.5V.
You can see and hear the impact of those cables' weight at 4.5V, with 6V that's not a concern ..with some cable management and 5V I'm sure it'll be just right...
The switch used in these tests is actually an ON-OFF-ON version due to my laziness. I will be using an ON-ON switch, which is way cooler :) The OFF part is really just another unnecessary click between ..there's no use for it.

Comments, questions, criticism?
DaOld Man:
Looks very good!
:applaud: :applaud:
Where did you get those small casters? I cant seem to find any that small.

Unbelievable. I'm starting to think I'll be able to pull this off this summer - I LOVE the videos and all of the pictures. Keep 'em coming!!! :cheers:
