Even with my torque based controller DS1 was ridiculously difficult.

;D Hahahaaa

Most of the time I can't really tell if you are being sarcastic or just being a *+%#. ;D

I'm hoping you just have a sense of humor.

Root cause why I haven't voted yet, as my only experience so far is with lean angle input & an xbox controller ... but I'm not liking it from the first day as it's not natural at all.

Vote away! That seems like the perfect example of "tried it and hated it"!
I tried both modes both with a ps3 controller and my diy handlebar controller without ffb. I hated it. I don't understand how anybody can use those modes without ffb. (Klax is the only one I've heard of that can do it)

You can change your vote when you tried with ffb! ;)

Quote from: HornetMaX on May 05, 2019, 06:57:00 PMWith a joypad (or, more precisely, without force feedback) DSA/DST make no sense.
You should address this only at people with FFB devices.

Saying "I tried DST/DSA with a joypad and it didn't work" is like saying you tried to dig yourself out of alcatraz with a toothpick and you didn't enjoy it. It's expected.

Well, the point was to find out how many are using DS. If they use a ffb wheel or a plastic fork, it is up to them, I judge no one! ;)

Well, both modes are directsteer, so same choice!

Or maybe you mean which one that was tried and hated ;)

I was wondering, how many of you guys use DirectSteer?
I know passerby and Marcel does, but how many of us are there out there?

Would be cool to get a race or training session going for DS!

Hahaa, Sapetoku.. Your rig will have more torque than Gaston's whole engine did!

That is a beast!! 20Nm.. I wouldn't want to be wrestling that thing on a go kart track! ;) It can pull your arms straight off!

Can you pick what ffb to use? Is that in game or in hardware?

Really excited to see the outcome of this!!
Quote from: poupou59890 on May 03, 2019, 12:07:17 PMFor the clutch, front break and rear brake (not clutch at this time I am waiting to check everything else before buying a complete set for the clutch) I use cheap chinese set of hydraulic lever on Aliexpress, than transducer (500 and 1000psi) in order to traanform the pressure apply to a signal between 0-5V. Here again, just plug everythign and that's it. https://www.aliexpress.com/item/Motobike-Racing-bike-lever-handle-bar-brake-pump-hydraulic-clutch-set-kit-17-5-piston-cylinder/32718100514.html

and for the pressure transducer : https://www.ebay.com/itm/Stainless-Steel-Pressure-transducer-sender-for-oil-fuel-air-water-100psi-2500psi-/172780141579

Excellent idea with the hydraulics! Quite easy to install compared to other solutions, and the feel must be perfect!

Quote from: poupou59890 on May 03, 2019, 12:07:17 PMFor the gear shift, I need to finish this one. I use real motorbike shifter from China (same set than the rear brake with master cylinder and pressure transudcer), I think I will use 2 buttons and put a screw next to each one in order to be sure that it will be the screw to stop the foot peg and not the button to avoid breaking it.

I used guitar pedal switches for my gear shifter setup. They are made for drunk bass players stomping them. Should be fine!

Quote from: poupou59890 on May 03, 2019, 12:07:17 PMSo for now I have every parts, I have use a cbr 600 rr template on Solidworks in order to draw my "chassis" with exact same dimension than a real one bike and I use direct steering with angle in order to be as real as it can. hope it will work :)

and if eveything is perfect I will try to use a 2DOF air sim balance system in order to add real lean thanks to GPbikes data ouptut. but I am no there yet. Hope it can help.

Even is the leabodnard is a bit pricey (around 60 euros) it is very easy to use, no driver, just plug eveything at the right place, put the usb and that's it.

Sounds really ambitious! Can't wait to see it take form! :D

The price difference between the Bodnar and the Leonardo is quite big yes (60 euros vs. 10 tops). And the Leo does everything that the Bodnar does (albeit "only" 10-bit). However if I had set a bigger budget I would probably go for the Bodnar anyway.. Just feels better to have a board that someone that really knows their s**t designed. ;)

Uuuuhh! Niiice!
What are you using to drive it?
What motor is it? :D
Quote from: MultiCOOLFRESH on May 03, 2019, 10:52:52 AMWhat do you exactly mean ??? :)


Whether you use the Leonardo, bognar, Xbox or something else, converting hydraulic brakes, load cells, wires or what ever solution you choose, to analog signals is the challenging bit. Programming the Arduino is super simple when you have a finished sketch.
Quote from: MultiCOOLFRESH on May 03, 2019, 09:59:16 AMThank you guys for the kind support :)

I will just have a detailled look at what you wrote to me and research this Leonardo thing :)


I can send you the Leonardo sketch I'm using. That is the easy part.

 Making the controllers is the difficult thing I think.
Quote from: TimboC137 on May 03, 2019, 09:56:03 AM@Chris_Beeves what is the leonardo's resolution for analog axes? I think it's 8-bit (255 steps), but I'm not sure. The leo bodnar board is 12-bit (4096 steps), so it might be the better choice. Although it is much more expensive.

More than enough for a game controller imo.
That really depends on what you want to accomplish.
For "arcade style" default steering, your way is probably the better way.
For "direct steer" I find tilting the wheel so the steering axle is in a "close-to-real-life-rake" angle, and then putting the handlebars exactly as a triple clamp would go on a real bike is the closest you will get to the real thing.

The Arduino Leonardo with "Joystick library" is easily configured for all the inputs you will ever need. (32 button, 4hat, 8 analog etc..)

Edit: this was a response to DD's post :)
Welcome back!!
( I'm new here, but anyway it feels nice that you found your way here again ;) )

It depends on how much you want to mod it!
What do you plan on doing? Full controls?

I just built a controller around a driving force GT wheel for "proof of concept". I'm using an Arduino Leonardo and different sensors for buttons and controls, and the wheel only for steering. For now I just put the handlebar on top of the wheel with Velcro straps. I don't want to ruin the wheel since I will be making the finished force feedback controller myself and keeping the wheel for playing with ps3.

I wouldn't call myself very experienced, but I do have some knowledge about the electronics and mechanics of it. I've learnt a lot in the process too. I'll put the project up here on the forum soon.

How much of your complete noobness is you being humble vs noobness?

Youtuber "Mixed Reality Sim Racing" has made a cool controller from a Fanatec wheel. You can see it in the community section of his YouTube profile. He modded a handlebar to a Fanatec hub and connected the controls to the pedals in some way. Worth looking at!
Take small steps and note your settings before! Too high compression damping makes the front wash out easily.
Let us know how it worked out! It's really cool being able to read the curves like you do, and adjusting accordingly!
