It's true that this is a "school" project, but we started it as a school project only because school could offer us young guys (16 at the time) materials to build one (I have no idea where we would get all the materials to build a simulator at the time on our own) and we do not intend to stop working on it when we finish school (in just a few months). It's our passion and something we love working on so if there is a better solution to it than the k8055 we will use it as soon as we can! We don't want this just to be a simulator to entertain kids who want to attend school. We want it to work as a good simulator that we know is accurate and works as it should.

Therefore I have to thank you for all the info. I will try to contact him and see if that controller would be right for us!

Also I forgot to mention that we use two sets of 5/3 valves, so we are able to use 2 speeds. Would that make the movement more precise and stable?
We experimented with 2 speeds a little but nothing worth showing off...
Also I do not understand the part of the program that switches between two speeds. Does it switch the speeds based on the math values or based on the pot position?

Today we got a chance to adjust our profiles a bit more.
The simulator behaves much nicer * 8-)
The "horse riding" style is almost completely removed (you pretty much don't notice it when driving except maybe a little bit on a long straight road when the accel G forces stop and the whole rig still shakes a little bit) and in some cases we even managed to make the cylinders completely stationary (they center perfectly and they don't move until math in the profiler says so)!
We also adjusted G forces and made three different profiles for cars with stronger or weaker G forces (currently only for Live for Speed, we were too lazy to make some for rFactor too today :roll: )

So we still have some hopes for future improvement (we still need to add some forces to completely replicate everything that is going on in the car).
Unfortunately no videos or photos were taken today so (my bad :oops: ).

Future plans:

-Improve profiles some more:
-add two speeds
-move the simulator to the old workshop where we had a beast compressor and much better results
-try to make the whole rig shake a little less (further improvement from the horse riding effect)

-make some "cosmetic" adjustments
-make a sequential shifter
-adjust wheel position
-mount speakers to the chassis


This is what we can currently do without and further funds. Hopefully we will be able to get good summer jobs or some sponsors for future improvements :idea:

Hello again!
We have been very busy last few weeks with our finals in school and the school workshop was busy so we could only tweak our profile a bit.
We have been searching for a way to stop our simulator with a physical button instead of the button in the converter GUI.
Sirnoname kindly gave us some pointers here, but we were unable to make it function.
We want to assign the joybutton1 on our g27 wheel for this function. The x-sim software recognizes nicely when the button is pressed but the simulator doesn't stop. Could anyone with some experience with this function help us please?

Thanks in advance!

Hello, first sorry for my english
I'm new into this world of simulator and some friend and I decide to make one as a school project, * our design is very similar to yours, but we get stuck in the control of the cylinders, so i have a question: how did you control the cylinders? do you have an interface or an arduino or something like that? we are using arduino but we can´t manage to make a code for the movement of the cylinder, any help is welcome.
