Nice one!

could you use a stock G25 or G27 brake in the same way you did

Yes. It only changes the feel of the action. My pedals are basically standard, all I did was mount them on the chassis.

Are your pedals in any way modded because I know for the G27 and G25 there are many mods to make the brakes better

Only the brake. I have an AP Electrix load cell installed.

Thanks for replying I think there might be a way to do it if you connect the potentiometers to the kart pedals.

If you can work out the pin out for the connector, the voltage and the resistor values, you could hook up any type of pedal system you want to eg. Hall sensors.

I like the way you setup the pedals. Do you have any idea on how to do that with those cheap thrustmaster pedals that come with the 458 italia because I have those and I'm planning on doing a very similar project.

No idea. I have not pulled apart a set of those pedals before. Sorry I can't help.  Good luck with your project, and make sure you post photos!

I think CastAR is going to be a far better option when it comes to sims.

+1 100% agree. The loading needs to be spawned off onto a thread, with visual feedback for loading. Ideally, the menu's should load very fast and then any other CPU intensive resources (like 3D views of the driver/kart) are loaded asynchronously inside that window.

I think I understand the question. It would be nice if those items could be separate skins so that you can mix and match them in the game as a driver configuration. The licensing problems for the game creator would be avoided simply using the same method that was used for the kart designs (generic, unbranded liveries), leaving it up to the community to create custom ones that are branded.

Clutch actuator now mounted.

Things left to finish:
- Create G27 FF motor mount
- Mount steering shaft linear bearing
- Create static mount for clutch lever
- Choose gear switching system
- Mount gear switch system
- Mount clutch G27 actuator
- Mount brake bias adjuster rotary encoder
- Build stands with castors
- Attach obutto triple screen stand system (optional)
- Clean up frame
- Paint/Powder coat frame

Successfully mounted and tested

Made a little bit of progress tonight.  Fabricated the bracket for the G27 motor.  Unfortunately I made a mistake welding it to the kart chassis, causing the steering shaft angle to be incorrect.  I will grind it off tomorrow afternoon, remount it correctly and then upload some pictures.  Should be able to plug in the G27 and watch it calibrate itself.  Getting very close to actually being able to give it a trial run

Actually a simple infrared switch is easier to implement. Can hook these up directly to a joystick interface.

Had another idea. To automate the "tuck" movement, an ultrasonic sensor could be mounted behind the seat pointing at the driver. When the driver tucks his head and the beam is broken it activates the tuck input.  I can implement this stuff in PIC C and share the code for others if you are planning to build your own kart hardware setups.

G'day, guys.  I know I'm slow but I made a little progress with the G27 FF motor mounting on the weekend.  The footwell is mounted in and the hole drilled for the steering shaft to pass through.  The G27 FF motor will be mounted upside down (underneath footwell) to make the job of building a mount easier.  The mount itself should be done by the weekend all going well, so I should be able to post a video of it plugged into my laptop and referencing itself.  Once that is done, I will consider adding a linear bearing to the system to take up some of the load of the steering shaft from the G27 motor.

I decided not to go with the gyro style cable system for the clutch.  There is not enough clearance for the clutch lever and the shifter during the 720 deg rotation of the wheel, so I need to come up with a static mount for the clutch lever.  Not as realistic but a necessity.

One thing I need feedback on is the feedback felt from engaging gears on the shifter lever, as I need to purchase/build a switch system.  I have tried to watch as many videos on youtube as I can to take a guess, so if you have any suggestions please let me know.

Another idea I have been playing with is adding an airbox with an ultrasonic sensor inside to pickup a hand placed across it, now that this feature is in the game. Thoughts?

I'm dedicating myself to finishing this soon, then I will be trying to sell it as I need the space in my house.  If you are in Australia and interested, I will sell it any any stage of completion.
