3Dof sim

Soldering all looks ok except for 1 joint, The bottom right JRK the A pin, Something looks a miss........This might only be the angle of the picture tho.

Yes the Switch looks ok, from what i can tell its a standard 600v 10a NC switch emergency off switch. As to how you wire it to your China PSU's im not too sure. I'm sure other's can chime in on that.

top right hand jrk top pin still a blob, not soldered very well
bottom right jrk definitely missing solder off the top right hand pin.
Take it back and demand warranty from the guy if they blow up when they nuke themselves when wired up. Sure as hell I would be after paying 60 euros for what looks to be a crap job.
As people have said, get some cheap kits , watch youtube videos and practice soldering yourself.

Ok which one should i go back with and what is wrong

Ok, all the bigger pins look good.
Soldering on smaller 3 pins look a bit suspect, however, there is not as much current going through them. Should be ok, only way to find out is wire them up

requested picture of Mounted JRK's with heatsinks.

Ok i bought this things now plus the killswitch any ide how should i wire all of this aa yes and a fise box here is a picture

You paid for that soldering job ?? wow....

and a premium price as well

Yes i did

As i posted new picture now im going on with my build ofciurse.

Do i need heatsinks on bouth black circuits or its enough only on the big one?

Next is making a panel for the butons as scratch did on his build il make it of polywood and there i will have a kill switch and the start engine button dont know if i need the on off button to if needed il add that to

It will be an 120mm 2000 rpm as nick has same box as nick used on top of the jrks

Yes for sure the big chip, didnt think of the others, never bothered, but big chip for sure and a good fan to cool them

Only reason i covered all the Chips with sinks is the fact i found a bunch of small sinks i forgot I had, I wouldn't worry about sourcing more sinks to cover all the chips, If it were needed we would have already done it.

Also make sure you dont mount the jrk's and sinks in the middle of the fan, You want the sinks to be on the most outer portion of the 120mm fan "circle"

like this

Here is my psu


Here is the fuse box the start engine button the kill swich and an extra on off button if needed



And here is a picture of some wiring that i found but dont understand how to use it

No clue how to wire all that, im sure one of the guys can break it down for ya lucian.

@Lucian i think something is missing and going wrong on the fuse-box. did you assemble it your self? do you have the fuses? can you post some pics with them?
should be looking something like this

No i bought it like that havent buy any fuse yet tomorrow

I got no idea either and I must be braver than most not running a switch and no fuses.
When I used to run a switch, all 2 times I used it, I ran it between the motor power outputs wires

Putting it there stops the power to the motors so the motion stops. But it does not allow the JRK to error out, unless of course the motor has overshoot or something broke. The you would have to reset the JRK in the utility program
The 2 times I used the switch on mine was just to stop the sim from jerking or shaking in between races. In race 07 if you sit in the pits, the car should jump a bit when a new person entered the game. After a while I just didnt bother.
