Trembling axes, when FF-Sensor is activated

[PAL123]

pity, have it as in the picture connected. but as soon as I hold the joystick with my hand and the sensor is activated, the yaw and the thrust axis tremble.

Hi,

No problem here I play BFV with my sidewinder ffb on Windows 10

[PAL123]

hey, big thanks for your answer :)

you have used also this 2x1nF ?
I do not have these two parts and have ordered them now

[Poil]

Yep :)

[PAL123]

Thanks, I will report as soon as I have the two parts

[PAL123]

I have still this tremble problem. As soon i have my finger on the Sensor, it starts tremble.

@Poil can you check if its the same for you?

I am having the same jitter problem with the throttle and z rotation, did you ever figure out what the problem was? I am contemplating tearing the circuit apart and rebuilding it if I have to.

[PAL123]

I wish I had found the problem. thought it was only with me

[PAL123]

nobody has an idea why the problem exists?

I'll be building this soon for windows 10. I'll report back how well it works and will try to diagnose any issues.

i know that there are two versions of sidewinder force feedback. One comes with a gameport to USB adapter and I have one without. Hope it has nothing to do with it.

@PAL123: Are you sure sure there were FFP1 joystick with USB adapter ever? I know there was very similar(but lacking Force Feedback) Precision Pro joystick, that came on updated version, that sported USB adapter: https://en.wikipedia.org/wiki/Microsoft_SideWinder But as I know, there were only two significiant revisions of Force Feedback Pro 1, there original with noisy fan, that has been replaced very early (because of complaints in reviews), by fanless versions (because FAN was never really needed, but the Microsoft enginers put it on case of...)

@isopix you are right, this is the Sidewinder Precision Pro. Sorry for confusing this
but I definitely have the Sidewinder Forcefeedback Pro

I can only confirm the issue with my setup (FFB1 without fan): Both axes start to tremble when the sensor is activated (but the stick is untouched). C1 and C2 values dont seem to change anything about that behaviour.

Pity that this wonderful project seems to be abandoned. :(

[PAL123]

bad to read...
i still hope that someone will adress the problem

[HotteX]

What I have to add: The tremble is there when I look at the windows setting, but at least in Freespace 2 its not an issue that is detectable ingame, even with a low dead zone.

My problem at the moment is, that the FFB is often lost, when I move the stick quickly (Stick starts flashing green). Sometimes it recovers soon after, sometimes, I have to repower the stick (Not the Teensy/USB!).
Behaviour is the same with no Capacitors, with 100 pF and with 1nF. With 10 nF no FFB is possible.

Anyone ever had that? I surely hope that its a bad connection caused by my breadboard and it vanishes as soon as I solder it down, but I have my doubts.
Issue gets a lot worse when I connect 4 potis.
