For DST mode the steering torque input is measured using strain gauges bonded directly to the steering stem so we are not measuring deflection but the force that we are applying at the bars to counter the servo action.

More modern electro-hydralic power steering systems with force feedback used for cars adopt a similar concept but use an electro magnetic transducer to deduce the torque - I did consider this as a possible steering stem solution using second hand ebay parts.

Using even a modest micro-controller and the servo controller closed loop adjustments you can easily keep up with the data rate from the GPB dlo interface.

I think you have pretty much grasped what I have tried to do; capture the counter-steering effect input by the rider and allow the resultant GPB physics engine output control everthing else   :)

And that's brillant !
Bravissimo.

Hello everybody,

back from a long bike trip in England and Wales (remember : the Welsh Road Race) and through France as well (4000km total) with Wifey, i found the seat i ordered to take place on my seat rig, where i put an old Peugeot 103 biplace seat but it's too hard and not wide enough for my old butt, so here it is :




I'm gonna place it later and anyway my rig is still undone (waiting for the electronics to be set for the FFB) and didn't tried yet the Beta 14 but i'm not in a hurry after what i read of bugs from Beta 14.

Crossed a lot of Mega-Goldwins heading to Ireland  ::)
(this Polish guy has a tail and a side-car !!! )

Hello,

update in the W.I.P.
still working on my rig and haven't restarted GP Bikes so still no feeling off the Beta 14.

Here is the reduction box (torque increase from the DC 24V motor). One more part to print, a big one, completly circular so i can put a wheel instead of the handlebar in order to have a steering wheel for Assetto or IRacing kind of game.
This part is going to take 20hours of printing at 90% filling.

The final reduction will be 1:58. Can be updated if needed to 1:104, i'll see.
Now, i'm waiting for the 32U4 to be finished with the DC motor driver and the encoder to catch the side the handlebar/wheel goes.
Hope to come back soon with the rig ready to launch.

Cheers.

Thank you Hawk   ;)

And i realized that i forgot to mention that with the 32U4 device comes a software to FILTER all FFB aspects... So wooble and kerbs effects as well.
I'm sure some of you will loves to have that with GP bikes. At least, to me it's important.

More on the next episode  ;D
