An other rotating monitor
« on: June 14, 2014, 02:30:14 pm »
Hi everyone

I'm working on this project for a while now. I take few time for me this afternoon to testing and tuning the screen rotation. It still need some adjustments but I cannot wait anymore to share it.

I'm using an hitec high torque servo with a maestro servo controller.

 I really like the servo idea, can you supply a link to the type of servo you are using and please some pictures of the linkage you are using? Are you going to automated the rotation or just use a button for rotation?

Here the servo I'm using. It's really small but strong enough to spin my 24" 16:10 monitor.

The rotation will be atomated, the frontend will handle when the monitor need to rotate.

I'm here if you need more informations or pics.

Exactly! I balanced my monitor to make the rotation smoother.

No, control choose only looks at the game controls.
You could use startcom to call a program that would do pretty much anything you wanted, based on game orientation.

That was going to be my next question. Using a servo to rotate an LCD monitor to me seems to be a much easier solution than what myself and others have been doing. No limit switches, no motor drives to change the motor direction, no special gearing or linkages and you can still use startcom to automate rotation.

I really need to stop thinking of servos as those cheap weak plastic things in the remote control cars I had as a kid.

GORF,

This is great...very simple and in the same league from a cost standpoint as the popular fiction setups that DNA Dan/Top Jimmy pioneered (that's what I currently have).  So quick question, do you have the entire weight of the monitor on the shaft of the servo or is there a lazy susan bearing or something providing support that we can't see from the pictures?  If a 24" monitor is being supported (and rotated by just a direct connection to the shaft of a servo, we that's damn impressive.  Do you have any other pics of the linkage/mount that you fabricated?  Did you get this into a cab and if so how's it holding up?

Thanks and again, great work!

I would like to see more pictures of the mounting and setup. I know the R/C servos are durable but I don't think you could mount the weight of the monitor directly to the servo. The picture posted looks like that is how it is ... long term daily use that way would for sure shorten the life.

 Thanks

Arg! It's hard to take a good picture... I'm building a slim cabinet. So it does'nt have a lot of clearance. Hope it help.

The monitor is supported by a vertical bearing and a servo hub who fit perfectly in the bearing. It's not mounted at the moment but I will post pics when it does.

Ask if you need more detail.

Ahh...Now it makes more sense  ;D

Really cool!  Can you provide model/spec info for the bearing & hub or the source of it?  That would be great!

Thanks in advance,
Chris

The servo hub come from there https://www.servocity.com/html/servo_shaft_hub___500__.html#.VBi2YcuV2Ag

I took the bearing on ebay. It was about 6$ and free shipping. Anyway, just find a bearing with an hole the size of the hub.

Cool, thanks! 

I had actually found the shaft/hub on the same site while researching on Google so thanks for the verification.  When I was poking around for the flange bearing I couldn't find anything that had a depth/thickness of less than 1" and my concern is that the shaft on the hub/shaft is only 7/8"...I guess I'll keep looking.

Thanks again for the info!

Bringing back a slightly old thread, but would this bearing, also from ServoCity work?  https://www.servocity.com/html/1_2__bore_flat_bearing_mount__.html#.VLLvadXF8n5

I'm just getting started on planning my little rotating project and am trying to gather all the parts/spec to get going.

Thanks

I don't know, that bearing looks promising. Keep us updated if you decide to jump in.

About reviving old threads:
Some people really get bothered by this, but it don't really bother me.
As long as the person reads the old thread thoroughly and is still decided that his (her) question was not answered, then I say its perfectly ok to bring up dead threads.
Others may have the same question but just didn't bother to search back far enough.
Now I do have a problem with someone reviving an old thread with a stupid off topic remark or question, or if they post a question that was already answered in the thread (but this can be excusable if the thread is really long and is a chore to read all the way through, but a little effort is expected. I find it hard to follow long de-railed (many times) threads.)

BTW, this thread has only been silent for not quite 4 months, so I wouldn't call it dead and gone LOL
