Showroom **RIP** - 6DOF project using 12v DC Motors, Sabertooth 2x60's (was MM's) and Arduinos + OSW

@SilentChill, are you still using the 6x670w Dell Psu with these actuator with the parvalux motor or you had to upgrade for more amps?

No i am using 6 LED switching 40 amp power supplies with a car battery now. There is a post i think on page 25 i think where I posted pictures of my upgrade for the actuators. The server PSU's kept tripping out all the time where as the chinese LED PSU's are great they just keep on working

Sorry for hijacking but after reading everything from @SilentChill, @SeatTime and @wannabeaflyer2 regarding the 6DOF platform with linear actuators I have a hard time finding Parvalux PM90 or equivalent motors online (You bought everything ) and motiondynamics motors are a bit too expensive. In your oppinion are these motors overkill or it's ok to take the leap and buy 6+2 until they last?
It appears I can't post links yet so it's about these motors on ebay ==> NEW-12V-DC-Electric-Motor-0-65HP-at-3500RPM-CW
Thank you

Yeah thats not gonna work, I would start again and write in English

@Pit please delete this and his post

Forgot to post these pics, I got a new 800w amp and got my transducers hooked up.

The effect was pretty amazing just using the LFE on the amp, the revs and bumps are just great. Feel the vibrations on the pedals and all through the rig and under legs/bum/back

Can't wait for gamevibe to be ready @yobuddy hint hint.

Nice . Reminds me that I must hook up my Buttkicker one day - still sitting in its box from when I used it on my old rig .

Went through your whole thread, all 41 pages of them. Incredible work; especially how you managed to change big things in very little time.

If you can spare a few minutes, I'd like to know a few things.

Have you sat in and/or driven sports cars on race tracks? How would you say the feeling is compared to your platform?

The actuators you've made, what is the maximum weight they have lifted? Like, the biggest person to have sat in your platform.

What do you feel provides more fun? Bigger range of motion with less accuracy or more resolution with smaller range of motion?

Big thanks for your whole thread. It has a vast amount of information. I will use a lot of what you've learned in my own build which I'll post about later.

A sincere apology as I had to make 2 back-to-back posts and I know the mod team might not like it very much. Please edit this post into my previous post if any issue.

I wanted to ask you, since you've run Monster Moto drivers in the past and are now using Sabertooth drivers. How would a middle ground, say Sparkfun Monster Motos be? Considering that Sparkfun's QC will be better, wouldn't it be better to spend a third of what the Sabertooth 2x60 costs? Or rather, end up with 3MMs for the price of one Sabertooth 2x60? I don't feel like the Sabertooth offers anything (within the requirements of powering the motors, extra features notwithstanding) more than the Sparkfun MMs.

Do you have an idea of the power consumption?

Never driven a on a race track

Heaviest person I have had on was 18 stone and it coped quite well

Somewhere in the middle, I use to like the big movements but now its a lot less than it use to be and feels better for car driving but for Flightsim bigger is better IMO.

Thanks for reading hope it creates a baby of some sort

I would never use MM's again apart from using them for small projects moving small motors.

The sabertooths you get what you pay for and they are pretty indestructible and are worth every penny, I have not had 1 single issue with them since I installed them. A lot less wiring to contend with and good support from the manufacturer.

If everything was running at full whack (which it doesn't) it would be around 2000w with a big 12v battery in paralell

Congratulations, SilentChill!!! Great work !!!
I had lost the update with linear actuators!
What speeds do you get with this actuators? 10/15 cm/sec ??

I think if it was going full whack it would be 333 mm/s I think

Great, very close to a SCN5. Nice update!
I think the 6DOF with Oculus Rift or Vive can give a total game immersion...
I have to find the time to finish at least my humble 2DOF! You gave me new inspiration

I'm getting to the part the most complicated ... tweaking ..

Question, how are you dealing with YAW in racing sim ?, for example dirt rally ?

Do you disable it ?, do you use the washout function ?

Another question, won't it be more realist to have acceleration simulated by pitch ?
It seems that in dirt rally pitch and roll are only link to pitch and roll of the car ...

During accel & decel if the pitch is going in the good direction it would be better no ?

Thanks mate !

Nice Build. - Do you have more details on the motors you used? What is the maximum weight you can mount on your platform? Thanks.

I use traction loss instead of Yaw. I use the 2 middle actuators and back 2 actuators for traction loss.
For surge acceleration I have the platform go forwards and pitch up slightly and opposite for deceleration
However the surge in Dirt rally is not the best it's very snappy so I now use more axis but use quite a bit of smoothing

Motor details are all here some where they are paravalux PM90 I think. Max weight I have had on the platform is 18stone person + platform, seat, fans, HOTAS, bass shakers, harness, keyboard, mouse , 12kg OSW and pedals

ha ok I understand, I allways tried to have surge perfectly flat because it is surge, but I can tweak to have the platform pitching ....

Great, I will try something

Thanks

Have a look at some of @SeatTime videos he use BFF which has proper 6dof I have kinda tried to copy what his does all be it not very well lol
