Feels like we're not going to reach an agreement on this right now, but I will definitely pick this up again (preferably with your input!) when I start planning the possibilities of a motion rig. Thank you for taking the time Vini!

OT I am currently debugging the force feedback in the game, it is quite harsh still even if it is much better with the latest controller. Filtering on the controller side don't seem to help much, but I'm giving it another go tuning the bike direct steer settings.
Low setting in game and high setting in the controller seems to be better than the other way around.
I had to try..

Vini

Good discussion anyway!
I will try to do some calculations myself as well but taking into account all the reactionary forces makes it quite complicated.
Ultimately, I don't think an exact calculation is necessary in order to identify the dependencies between the different parameters. Thought experiments are the way to go in this case in my opinion.


Very intersted in your analysis of the force feedback, specifically under acceleration.
Would it be possible to make another riding video where you show a synced graph of the logged raw force feedback data?
The behaviour while wheelying and sliding would be especially interesting.

Absolutely!
No, I agree with you there. In the end it is about what 'feels' right when you're on the rig. That doesn't always match up with what 'should feel' right.
My thought is that either way, I'm going to be building a seat with a tank to hold on to. When that is finished, I'll make it tiltable and get a strong friend or two to act as actuators and just experiment.

I'll take a look at it as soon as i get the time, hopefully today.
Sliding.. Have you tried hardcore mode? Most of the sliding I do is on the fairings in the gravel trap. ;D

What kind of sliding do you have in mind? Power sliding out of curves I can probably do with the MotoGP bikes. Into curves... Don't know..

Had a little go on the 3D-printer again and tried to tidy the insides a little. Turned out quite good! The motor driver pcb mount didn't really work out the way I thought though so I'll make a second version.
Also a cover is printing right now. Hopefully it will fit well. Had a small mishap with the filament (didn't really think about how much was left), so it'll be a two color piece.. :D
Glad I noticed sooner rather than later.

Chris_Beeves

The cover turned out fine! A bit bulky maybe, but I'm happy!
The little rear brake thing seems to do it's work good too!



I want to paint the motor part, but at the moment I'm too lazy to take it apart.

Cleaned up the electronics a bit too. It'll be nice not having to be so careful when setting up.

After a little break building a sim wheel of the other side of the hoverboard:

Right now I'm working on making the wheel buttons wireless over Bluetooth. It's working, but for some reason it keeps resetting every thirty seconds.
Hopefully when this is working, I can implement it on the handlebar controller too.

Starting to work on a better seat unit. First I will just make it like a seat, but leave it open to add motion to it in the future. First front/back lean to simulate acceleration and braking.
I had to try..

Finally got the wireless knee sliders working! IR has it's limitations but it is quite easy to use compared to the others I've tried.

Sooo, there is a chance of this happening;

Been working on getting some nice buttons and joysticks on the handlebars, but I keep getting stuck in CAD design. Just not happy with anything so far.. Any ideas on button types and placement?

Made a new hall sensor throttle that works way better than the old e-bike one. V2 just inherited the twist-type spring from that, and it feels way better!

I would just try to replicate the layout of some real MotoGP bike.
Why do you need joysticks on the handlebar?

Can't speak for Chris but I use the joystick on my handlebar for rider movement in GPB and MXB.

Chris: What does the twist type spring look like. Where did it come from originally? Been trying to find one for ages.

Well, yeah. Quite obvious now that you mention it! I'll definately steal that design! Thanks man!

Like David said, I thought it could be used for pushing the bike and moving the driver for those who don't use VR or HT. From the beginning I just wanted to do it because the little psp joysticks were so cute.

I took it out of the crap e-bike throttle I have been using until now.
Looked just like this

Now I think I will just get some piano wire and make my own springs instead.

Vini

I'd put the joysticks under the handlebar ends. Approx where they put the rear thumbbrake on real bikes.

Maybe I can help as my steel supplier also is the company that does laser cutting for my parts....

If you want to talk we can skype as I made some joystick housings on my original systems in 2010

Also my bars are changing as working on full FFB with direct drive motor......

Heres the old one from NEC show for Ducati:



The laser cut ali and steel is a REAL good price btw as I do so much with them.

I love the work your doing m8
