Finished my 2DOF motion sim for P2D v2

I just finished my 2DOF motion sim project. I am using the Oculus DK2 and the SIMTOOLS motoin driver.

AND IT ROCKS!!!!!!!!!

Its ultra cheap but extremely cool.

what i used:
2 old whiper motors 12V
2 30Amps power units
2 pololu controllers JRK12V12
1 old car seat
1 universal joint
about 6 meters of steel tubing
1 good friend with welding abilities ;-)

Now just trying to find out the best Axis settings for realistic motion.

Willing to share ideas!

Peter

got any pictures or videos

Some pics:

I was just uploading. Thesse a not the latest setup. I changed the position of the motors. I made a cross beam behind the pedal to releaf the tention/force on the motors.

I wil make some new pic and post them.

Must say that the motors have a lot of power. More then i expected. I am considering to place the moters back at the rear of the platform so i have more motion movement. Although i found out that i dont need a lot of motion when i am using the oculus dk2. Its the sense of motion that does the trick... not so much the amount of motion..

Do you have a motion sim yourself?

I would hope you aren't running those JRK's for any lengthy period of time. Running without heat sinks is asking for trouble. Fan and Heat sink are mandatory for the JRK's

PS seat mover's style with motor's out back and long arms coming up will help your motor's tremendously.

hi peter. im in the middle of making mine at the minute. just waiting for a couple of extra bits then i will be onto the software side of things

Good call Noor, Those motor mounts look woefully under sized and will most likely have some flex.

Hi guys,

thanks for your input!

@Nick Moxley : thanks for the heads up. Im running the JrK's without heatsinks. I have been running them the last two weeks for a couple of hours every night. (So far) No problems. But i am running my sim in my garage. Believe it or not, today it snowd here (i live in holland!).... so cooling isnt a problem yet...
I have some old videocards. I will use those heatsinks.

do you know if the JRK's have some kind of overheating protection? like intel processors... if they overheat they just quit untill they have cooled down enough..

@grammy : can you show some pic's of your sim? I am very curious

@noorbeast: thanks for the link! I wil compare my own settings right away. The motor mounts are pretty ridged. But i changed the motor placement. I made long arms just as you advised. I wil post some pics this evening.

Thans guys!!!!

hopefully i can help you as well!

Hi guys,

as promised some pics from my sim:

an overview pic

Running the JRK's without a Heatsink and Fan blowing ideally directly on the heatsink, is NOT advisable. Yes the JRK's have a Thermal Shutdown, but why even take them to that point. Get some Stick on Heatsinks, or as you say Chop up some GPU sink's and get them jrk's running Bone cold as when you start to find tune the profiles and expect some decent motion out of them, you Surely will get them too hot even given the Cold nature of your shop.

some extra pics:

and some detail pics:

as you can see, its not the most beautifull sim . but using a oculus rift i dont see the sim anyway .

its cheap and functional. i can fly with the yoke (boeing and cessna's) and also with my old f16 hotas for jets and helicopters.

@noorbeast,

i just triend Archies motion settings..... somehow i doesnt work for me. using the extra1 and extra2 for roll and pitch..... i'm so motion sick right now! . Seriousely, i am done for this evening. I am just as green as the emoticon. it could be because i just flown helicopters... some how flying helicopters tends to have more effect on motion sickness

Thank you to share, it is worth learning from.

@ MAYA One: thanks. I got a lot of information and ideas from this forum. Without you guys i could have never completed my own rig. So now its time for me to give back.

@ Noorbeast: youre absolutely right. If the motion is off from what you see then its just a vomit machine. I found that the extra1 and extra2 simulated the acceleratio for botch axis. Turning in was ok but after turning in the sim right away turned level witch does not feel right.

today: i will try combine my own settings with Archies's settings.

By the way: funny thing: yesterday i flew an old Huey helicopter, then i turned into a fast corner the complete sim started shaking. I guess it whas the fibration from the rotor. Realy cool but also scary.... it felt like destroying my rig!

and landing on steel skids is not as soft as landing on air filled tires with shockabsorbers. what a bumb!

@Peter van den Esschert . here is a link to my build so far. i have been working on the wiring the last couple of evenings so will hopefully be finished tonight of tomorrow if last part arrives. I have not built the top frame or seat yet as i will just clamp my old non motion rig to it for testing. pictures are on bottom of page 4. its just a motion platform at the minute and not finished yet. the traction loss actuator still needs sorting.
