OCSM Sim (2dof + traction loss) project

@Wanegain: you were right my friend! It was the PSU. Today, switching to a good worthy of trust PC PSU completely solved the problem.
I don't know why but although my PSUs are 1.2kW and my motors about 200W (measured with the clamp meter in game) those spikes cannot be handled.

@noorbeast : which specific kind of issues? I initially had problems because the wheel was between the camera and the headset. Now it works really well compared to the previous set-up. Anyway something more can be done, for example put a damper in the camera pole to avoid vibrations to mess up the camera readings.

There aint no way in this world that the camera wont lose tracking, it will stutter and stammer and jump all over the place on a driving game. Flying Simulations work fine but not driving.

If you find a miracle cure for the camera other than taking the tracking cable out of it I will pay you lots of $$$$$ for it

The problem doesn't come from the power (I'm sure you can easily get 1.2kW) but from the current peaks when changing direction at full speed.

@SilentChill: I'm sorry due to my poor English I cannot get what you mean.
In my opinion the camera can be used on rig, it's just needed a really rigid pole and eventually a good damper (or whatever system) to exclude all the small movements (produced by the ffb of the wheel for example, or by the rig itself).
It would be great if the Oculus settings could provide a sort of deadzone..

@Wanegain: Thanks again Wanegain!
What I wanted to say is that the 1.2kW server psu is, according to specs, able to give 100A, while the PC PSU about 45A (I don't remember exactly at the moment).
Theoretically, even in the hardest situation, the server psu should better handle peaks than the other one. No?
In reality is the exact opposite.

Unfortunately those server power supplies are not designed to be used in our application and have protection circuitry that can get in the way of driving motors. I use simple LED high current power supplies and have never had a issue.

Hi all guys!
I'd like to ask if there's a way to download the assetto corsa plugin which I already had without using coins again (I'm building a new PC and I cannot find the plugin file)..if not no problem, I will wait until I'll have the coins.

Thanks in advance
Marco

Thank you so much noorbeast! You are always so kind!

I'd like to discuss with you and the others here in the forum about GMR sensors compared to Hall effect pots, is there anyone who tried them?
I found this datasheet which seems quite interesting (only few drawbacks, like 4 wires instead of three), but I think I'll give them a try!

Hall effect pots are a drop in replacement for standard photometers whereas the GMR listed is much like a rotary encoder, but hall sensing rather than optical. The GMR sensor that you have listed used a communication interface (serial/PWM) to talk to a computer/micro rater than an analog output.

Thank to all Forum for contents, support and patience!!!!!!!!!
This is the final video to celebrate the end of the sim prototype.

Sorry,
It is public now!!

This video show our solution for third movement! It Work really fast!!!

congratulation for your simulator !would have a picture of your gear system for traction loss effect?

Tomorrow I'll post a new video! Thanks!!!

Careful on your TL Tuning center #'s. You can easily trick the inner ear into thing's that Are NOT actually happening.

Woah! Really fast and responsive traction loss!
Well done

Bel progetto complimenti!

Could you please tell us what is the lever length and type of motor for your traction loss system?

a picture of the system would be welcome
