Quote from: Vini on May 12, 2020, 12:23:42 PMDoes the front stay misaligned (like this) or is it being auto-centered?
Yeah, it stays misaligned. The bars lose pretty much all resistance when the wheel leaves the ground.
My guess is that the ffb is calculated mostly from the "steer torque" and, even though it is extremely noisy at times, works very well 95% of the time (If you don't use too much force, then it goes bananas).

However, I have been experimenting with having a small spring effect in the background though to stiffen up the feeling of the bars a bit more (if I could just raise the force that wouldn't be necessary). This is present even when the wheel is off the ground, but that is not GPbikes fault just mine. :)

Quote from: Vini on May 12, 2020, 12:23:42 PMDoes the front send the bike into a wobble when its dropped and not aligned?
When accelerating, not so much. But if I roll off the throttle too fast, it gets quite nervous on landing. I would say it reacts quite similar to how a real bike would.

Thanks Manu!

Thanks guys!

@Vini, no I changed to angle when I made the move to the standard force feedback. Torque didn't make any sense. Haven't tried it with this motor, but I suspect it would be similar. I'll give it a shot.

DS2(angle) when wheeling is very nice. The bars get light and give a nice kick when touching down again if the angle doesn't match.

In the end I lost the rear. I held on to the bars harder than the motor could push.
It's a compromise. Force feedback is a little buggy in the game and setting too high force makes the whole thing oscillate.

A brief demo of the status today

Had the first test run today with the new motor unit. Massive improvement! Feels like it has 10 times the power and resolution, even though it should only be about double in theory.

It was quite the challenge wiring and soldering the little motor driver card. Impressive how strong it is for its size.

Got some parts together:

The software side is a bit more tricky on this one. Getting som great help over at the xsimulator community though.

Not much lumber left now!

The DC motor isn't quite doing it for me.. Making new plans:

Printing some details the coming days.

Does anyone recognize the motor?

I've been trying to make the knee sliders wireless the past few days. Been working on a 433MHz solution that I got working very well with just LED's, but lost all range when running the motors. Next test is to use Wifi units instead and use UDP broadcasting. Should give me a lot better range, but it is a lot more complicated..

Whatever happened to this? Beautiful model!

With the great programming help of @maggikk22, today I got my knee draggers working!
I use an Arduino Nano and a program running in "Processing" (maggikk22's magic).

With the little knob (potentiometer) I can set on the fly what angle they activate. Silly fun!

Tidied up the wiring by the arduino that I use for the hand and foot controls and went from "breadboard" to a proper prototype board where all the controls are now detachable.

Makes it a lot easier to store and there is less noise in the signals.

Looking into making some kind of seat that works better than my piano chair now.. It's not very ergonomic at the moment.

I have been testing different settings, bikes and tracks. It's funny, the tracks I have actually ridden irl I make the same exact mistakes in game (with a lot less crashing irl).
The Cup R6 (by?) and Javi's 125 are the two best bikes that I've tried so far. Ffb is still buggy, I have to set it under 40% or it starts oscillating mostly when upright and braking.

Starting to realize I have used a less than optimal motor in the controller. It's quite notchy and I think that that is the main problem causing the weak center feedback.

At times it's loads of fun though! :D

Do you have separate inputs from the counter steering and the lean, or are they blended?
Do they operate independently?
If they are independent I would probably use something like h106frp describes and hook the handlebar torque up to a servo that is connected to the counter steering axis and another servo or motor that feeds the lean angle back to the tilt part.
If it works for Assetto Corsa, it will work for gpbikes, no problem.
Looks promising! FOC stepper drivers aren't exactly cheap.

Thanks h! I'll look into that.
Tried just using a diode on the power output, but that seemed to trip the motor driver instead.
I guess there are no short cuts here..

Played around a bit with the settings and it feels like I'm onto something, but feedback in the center is very weak..
Anyway, here's a short demo of how it works today;

I also took apart my "race hat", the hat I put LED's on and used with Opentrack, and made a clip for my headphones instead. Works great!

Tested directsteer.cfg but I don't understand what it does.

Can't really tell the difference. What range are the values in? -255 to 0?

@Piboso, could you include some sort of specification in the first post?
