For the AMC the 24 VDC power supply is OK.

And yes for the Logitech card use a 12 VDC power supply because the operating range for the inputs signals of the AMC must be between 10, 15V.

Your switches are ok.

Loop gain must be fully CCW (12 turns)

Test current limit 6 turns and then turn reference gain. When it's ok you stop.

For the degrees of rotation for me it's ok, because when you play you use all the rotation of the wheel isn't it...

thankyou!!

i changed the 24v dc power supply for a 12v dc power supply- immediatly, i could feel the difference in the wheel resistance- it got weaker.

next, i turned the loop gain pot down as far as it would go (you can hear clicking when the pot is fully out, mine was set at approximatly 4 turns CW!)

then, i turned down the current limit pot as far as it would go..then turned it up 6 turns CW.

lastly, i turned down ref in gain pot fully.. the wheel had no resistance. as i turned up the ref in gain pot, i could feel resistance getting stronger.

i set the ref in gain pot while testing with outrun2 on ps3. i kept turning up the pot clock wise (with the wheel on full lock) until the motor started knocking/banging (and the green led on the AMC flashes).. from here, i turned the pot down one full turn CCW.  

this felt very good, and MUCH better than it did before- ffb effects seem much clearer and more definate.

next, i tested with NFSshift, because i know the ffb in that game was very powerful.. to my surprise, i was getting a lot of rumble and motor banging/knocking with this game. so, turned the ref in gain pot back down until the motor stopped banging.

now, all is well and im even more happy with the happ than before. i did have it woring well, but obviuosly, with too high voltages, i was missing many of the ffb effects..

i thank you for your help!

GT5 plays even better now!!  

..

note, i am still getting some rumble/shaking while the wheel is in the centre position.. is there any way to sort this?

cheers

Your potentiometer wheel has been changed with a 10K ?

Saddly it's the little problem with this system, because the passage right-left is more direct than the Logitech (Logitech motor wheel 1/16, Happ 1/2, and the motor is very strong...

PS : connect the metal of your wheel to the ground of the AMC too to not have interferences...

thanks stef..

my steering pot is 100k im sure.. this is the same size of pot that was on the logitech steering wheel. the original pot on the happ was 5k.  i do have the metal on the happ grounded to the AMC.

your explanation of why we are getting unwanted rumble makes perfect sense.. and it is now a little better after setting the AMC pots correctly.

cheers

Hi im Purplec I have completed the same hack as the sharkfactor except i have an interference problem on the wheel.

When I turn the wheel from left to right the triangle buton presses every now and then.

I have connected the ground wire fom the amp power supply to the amp and then to the metal of the feedback motor, but I still have slight interference.

Is there anything I an do its very frustrating.

Thankyou for your help
Purplec

hello thesharkfactor

is it possible to have some pictures of the push button on your wheel ,i want to do the same 

thank you

The sharfactor sold his cab, what push button are you looking to get a picture of?

Maybe I can help

hello

i'm looking for the 2 red button on the wheel (blue cicle on the picture)

PurpleCone for the interferences I had the same problem with my Logitech, but strangely not with the Thrustmaster F430 hack that I use now...

Aganyte has not the problem because he uses for the buttons a Keyboard Hack.

So the better solution is not to use the Logitech Buttons but an independant interface like this.

Supernono, le volant est un volant spécifique avec deux boutons inclus, Shark n'a fait aucune manipulation dessus...

this is where to get the buttons.
