I am New to DIY sim building. Anyone chiming in with help is great.

Is this power supply any good?
My controll board is rated 12 a continus so I didn't want to go above that.

Absolutely not! You’re thinking is in reverse here. You want to have more amps than you should ever need if possible to “supply” everything with enough current aka amps. The dual vnh5019 can deliver up to 60 peak amps with both motors. So ideally having that at minimum would be good I would think but you may get by on a lesser amperage rated power supply if it can deliver higher peak amps for a long enough period. Adding more amps than necessary wont hurt anything though in normal operating circumstances.

Btw Another benefit I didn't think to mention earlier was that if you had gone with two single vnh5019 motor drivers instead of the dual, then you could have gone with individual power supplies on each one to split the load up.

than this is the smarter buy? 12v 30A ?

Ive got 2 x 40 amp versions of those on my desk racer.

wow thats alot of power. you are pushing 80amps?

Something like this should do the job!

But if that's a little more than you want to spend something like this should work good also.

Unfortunately, at some point as you try to pump out more amperage out of a power supply, the price grows exponentially. You may be able to find a better deal than this though if you spend some time looking! Or it may be less expensive to just scrap your dual motor driver and buy the single ones. Then you could go with 2 much less expensive 30 - 40 amp supplies.

Or another option would be to buy another dual motor driver and then use it with the one you already have as a single driver like this. This will double the available amperage available to each motor.

@bsft It would be fantastic if Pololu would make a jrk using this configuration also!

The downside though is if you were to use the full power output of the dual turned into a single, you're back to looking at larger amperage power supplies again! But probably two of them this time! Although a large enough single power supply may get the job done for both drivers like the second one I posted above if you're motors peak amps don't go to high.

lol 15000.
i was thinking of buying two more of the 5019 and hook them up with rufusdufus code. for 3dof

but i will try and get this first one to work first before i get extrafigant.

I was just not wanting to blow my controller by puting to much currant throgh it. but I guess that not a consern.

go big

yes. 40 amps per motor under the right - wild motion . Ive had my motors at 530 watts overdriven easy, thats 44 amps spikes.

It would be nice yes, and we have asked pololu if they have a larger JRK in the works. Their answer was "not really" , its sales for them, rather than catering for a few sim builders. The main use for the JRK is battle robots. Mind you, since @eaorobbie introduced the JRKS here, the size of the motors the robot guys use are now a lot bigger than what they started with. I have heard of a robot with a 12v boat winch motor and 3kg hammer on it. Crunch.

@bsft I would think they would want to have something to compete with the sabertooth 2x60 and others but, as you stated, maybe not enough motivation for them to do so!

@james wheeler I ran across these power supplies today that look good for you at $60.00usd. Free shipping to USA but don't know about Canada.

Looks good man. Well done. I can see however that the seat is not sitting on the back t-bar and I suspect yo may be loosing a bit of feeling as the seat is moving separately to the frame.
Otherwise, well done.

I have upgraded my seat.
1st I did try bsft suggestions on attaching the control arms directly to the seat but I found it to aggressive. The spongyness of how i have it set up with the t bar i think simulates shocl absorption better.
2nd i added a 10" sub into the back of the seat (there was no room under it) and hooked it up to the rear chanel of the 5.1.
3rd and this is not completed yet, I ripped a jetta dash out from the u-pull complete with radio and tack., speedo cluster (also heat controls). I have the radio working but would like to get the instrument cluster working if its possible, to show me the rpm and speed. I took apart my momo wheel and installed it into the steering column and moved the shifter down to the center column.
NEXT is to mount a 42" 3d tv to it

Oh i forgot to mention my settings
So after getting a little annoyed with how roll and pitch didn't feel right at all i started watching the tuning center and came to realize that sway and surge was what I needed. So I set the sway to 66% and same with the surge with axis limiting to 80%. And jumped into dirt 3. But after flying off the road a few times i noticed that when I was sitting in the ditch sideways the chair was still flat. Looking at the tuning center again i saw that my roll was way up. So i went back and change sway to 60% & roll to 40% (I made sure that roll and sway were opposite from each other) using 100% of my 80% axis. I did the same to sway and pitch. And jumped into dirt 3. Then I noticed that I would gwt flung side to side alot but not forward and back much. So off to change again. I noticed that the motor arm with sway/roll moved opposite from each other and surge/pitch moved together so i theorized that sway/roll had twice as much movement naturally the surge/pitch. So i changed sway to 42 and roll to 26 which gave me 66% of axis and i left s/p at 100%. And jumped into dirt 3. It was better. The 2 forces were more equally matcjed but still a little dominant on the s/r side. Figuring all that out made me think maybe there was more i could do. So i had my neighbor take me out in his Impreza while I felt the car through the corners. I noticed that the car never felt like it would sway simply side to side but felt like the outside rear would sink alittle. So I changed it again. This time i watched the tuning center for a force that acted like sway. Extra 1 was the winner. I changed my sway to 40% roll to 16% and added extra 1 (set in opposite to sway but the same as rol) at 10% with 10% smoothing to make it feel as though the car kept sinking into the corners. That left me at 66% and surge/pitch at 100. And jumped into dirt 3. Perfect. (so far)
So here they are

Sway 40%
Roll 16% opposite sway
Extra 1 10% with 10% smoothing, opposite sway

Surge 60%
Pitch 40% opposite of surge.

Now its great.

well done, profiles are individual and take time to work out
