@HornetMax :

that's the point, if he uses transductor its to get pressure on the hand as a real brake, so the feeling would be the same.

And i'm glad to see that we agree with DD, theory and practic are oftenly different, it needs to be tested and retested.

"The Bumblebee can't fly, Aeoronautics theory has proven it. But he doesn't know about aeronautics, that's why he is actually flying..."   

I can't understand or argue correctly with you guys but as an Ingeneer, i did a lot of theory and once in situation, the theory stays a theory, the reality is sometimes way differents.
And my feeling is that the DD system will have problems anyway, as Uberslug seems to says it too.
(my lack of words is horrible, my technical English is so poor i'm censored by my language limit, very frustrating but too bad for me).
found out that what you call caliper is actually what i was calling "fork-cylinder"... very frustrating.

@DD : Can't you ship your systeme without liquid and the client could filled it up by himself no ? (if it's for GOOD reasons that doesn't depend on you but on International Flight Rules, any client will understand)

Edit : Like that ? 

When we brake on a motorcycle, actually every wehicule with liquid brake on disc, we first push the fluid with the lever to move the "fork cylinder" (sorry, i don't have the exact technic word) so it press the pad to the disc. But the disc constantly turn (till you stop  ) and by his movement keeps pushing the pad back so you maintain that force through the pressure you have on the lever. On this system, the pressure is made, the little tiny circuit is filled up, you test with the lever, you have pressure. But if during a lap, you keep pressing, pressing, nothing move, the pressure keeps being directly applied only to the round metallic cap that press on the silicium plate (that catch the pressure by deformation if i understood what i have been reading about it).
So in the Allan system, i think but i might be totally wrong - i just give an idea that i have in my mind - that the pressure will keep going up to a certain level and something is going to leak or break after a lot or maybe not a lot of actionning. As far as i know water is not compressible, what about this DOT fluid ?

Whatever type or brand, i really think it should be way over the max limit, at least 100 bar because the transductor is connected right at the outside of the master-cylinder and there's no mobile parts inside, no tube length to absorb some of the pressure.

Sad but understandable... 

Thank you for taking this servers up. 
That was nice !

Heu yes, i would say 1000psi minimum after what i saw in this place.
They're using a 100 bar transductor that means 1450 psi.

(it's a Variohm brand, probably EPT9100 series, hard to find "individualy" as far as i searched for )

(Good  that it did that at testing, but the thing is if it start to leak you gonna have liquid everywhre with so much pressure DD ? And better not explode entering Correntaio 'round 350km/h !!! teasing you )

As always, very interesting job !!

 

That looks pretty professional and can't wait to see that working !

Almost 150km autonomy... that becomes really interesting. And about noise or sounds or chorus of the engine, i will say that when the GP was on 2stroke engine, that was exciting and since 4 stroke appears, since they don't regulate the level of decibels, maybe it's because i have ages but it kills my head this 140 db when Rossi and the other ones turn away in the corner  facing you, even with the little ears plug to the max inside, it's too much, almost like when i was working at the airport, it's too much. Since then i have hard time staying all day long on a circuit, it's getting too loud.

Hi everyone,

i'll do as Uberslug, i've been practicing on my side, at first with Mister Kerazo, last week-end, but with my "rig" (Joystick T16 Thrustmaster !!! ) i'll never pass under 1:39:xxx that's why i won't come to the Hotlap event until i have made my own handlebar. Try it with a steering wheel but didn't like it at all.
I'll look at your replay as soon as i'm back home.
Thank you guys and Uberslug if you want to practice between newbies unequiped, let me know, i can start a server whenever (in the next 2 hours or so).

Hello Poumpouny,

and thank you for your feedback, i always consider than more brains are on a problem, better the solution will be at the end !!

And about what you says :
About natural mouvement, as i said i spent hours this last week analysing the mouvement, even put the GoPro of my son to film my hands and handlebar on my Pan European or on my other son ER-6 Kawa and i found on images what i was doing without really knowing.
And this mouvement, despite what you think, is or begging natural to me as every motorbike riders that ride for a while.

About the horizontal axe moved by the fact that i counter-steer on the vertical axe, this other idea (i post the "old" one - from 2 days) and this one is the news one from this morning at the breakfast time.
And i think that will absorb more the bike leaning mouvement to not trouble the rider leaning movement. Or, if it perturb anyway, i will have to make the rider leaning harder. I want to try anyway because that's how it feels to me.
About EdTracker Pro, that i use since it's out on the market, i will only put the Back and Front rider leaning.
I will be seating on my chair, not on the frame that's gonna move left and right.
So yes, want to ride a bike seating on a chair looks akward but that's the challenge.

About FFB, yes, i would love to FFB my vertical axe but i'm not sure (that was my question to DD) that the FFB is actually to copy the reality, meaning bloking me to turn if i brake hard, as in reality. And on a race, guys are allways braking to late and have to force down the bike on the side they want to go. Its natural centrifuge and centripete forces, plus the gravity and the wheels inertial mouvement. On the regular street bike, you brake, turn and the accelerate, on a race bike you gonna brake and turn but still brake on your turn (on the angle) so braking will have a tendancy to make the bike stand back up to the vertical and is going to refuse to steer and then you have to force it to put it into the curve, that's what i will love to find with FFB but i'm not sure it acts like that. (where to  catch the data for that ?, as i wrote somewhere else, as a Motec in racing cars).

And about DSA or DST i have no idea what is it, information in here and about the game is an archeology type of thing, so if you know what it is, i'll be more than happy to learn about it...

(what you say about vertical axe is interesting and i started to draw something like that but the draw isn't finished, i'll give it a try to the end of design and post it in here)




Edit : what you couldn't see in the other draws is that the horizontal axis on the handlebar is at the same axis as the riders leaning axis. So if i push my handlebar in a horizontal plan (to counter steer), it won't be pushing the rider leaning left and right.
And if DSA or DST doesn't give any feedback, i was thinking of using limiter after calibrating is done in order to give myself a max angle of 60° or something around that. (today, i'm using a joystick and a drum pedals with EdTracker on it for the rear brake, it's a catastrophy !! and i have no feedback anyway so...)

Hello riders,

yes, i'm having the guts to call it "Realistic"... We'll see.
But i've been riding my bike and others this last week to check the mouvement. I'm driving bike for more than 30 years and i never really paid attention to the cinetic even after watching every week-end every possible bike race in the world...better later than ever...
And  then i tried to find a good way to reproduce what's happening on a bike AND that i could "ride" on my chair in front of my screen... --> GPB !!
Because i don't want do a real frame bike and having to use hydraulic or electric servo to shake, lean and move the frame. I don't have the room and more than that i don't have the money.

And so...
In red you have the handlebar that will be counter-steering to lean on the sides. This mouvement (vertical axe) will be short angle but hard to do (piece of metal into a big rubber that makes the mouvement harder - trying to reproduce what is real and what a steering absorber will do). The green piece will then turn left and right in a horizontal plan.
The blue part will be the driver leaning and can go on a horizontal axe from top to bottom, this will be a free mouvement, inside a "teflon" piece that will make the mouvement smooth (as in a bearing wheel).

Obviously, the feet parts are missing - brake and gear - and all the buttons on the handlebar but that easy stuff, what was annoying is to find a way to reproduce counter-sterring as it is in real life. I want a be able to ride in GPB without thinking of the device, just being absorbed by the screen. Like Assetto Corsa with a steering wheel, you forget about the device, you drive.

Now it's going to be time to make a prototype and then improve the stuff.

Thanks again to DD because he helped me a lot with the Leobodnar stuff and since HS1, HS2 and soon HS3, we have of excellence to follow, doing my best !!! (and if i could buy one and race instead of burning my brain into that rig, i'd prefer !!! )

Hello DD,

just back to you for a little question...
I know you don't use FF in your device.
And i'm kind like you about it except maybe for one feedback : When you ride, and brakes and try to start a curve, if you brake a lot the bike as a tendancy to go straight and to avoid the leaning so you have to force more (including forcing on your inside foot support - sorry i don't have the accurate word in mind) and try to lean more to force the bike into the curve.
If there's any way to get this from the software (GP Bikes) that will be somehing interesting to use but do you know how to catch data from the games ? As a motec that you feed with the data from the game (GTR2-rFactor-Assetto...)
Is this something that i need to ask PIboso about or do you know if it's possible ? (actually i'm wondering how the links between the game and the controller works for the FF system.)

Thank you and "bonne soirée" to you !!

Interesting but it's not to sell i think or only to research center, it looks like its using Hydraulic system, so you need heavy devices and the price might be as heavy as well !!

Can you ou did you found other video about it ?

_it looks like there is a longitudinal axe (the direction the bike takes if it was going on) but we don't see the bike leaning, just steering, so between 0 and 10km/h.

God, that sounds good and fun, i wish i could.
Soon, not now but soon

Anyway, thanks for the initiative. 

Happy !!!

And don't thank me or just to be a messenger... Manu is the one who knews all about
