This is my custom Happ-F430 steering wheel...

dsc05134u.jpg

In 2008 I have found this topic...
http://home.comcast.net/~mshaker/marks_arcade_006.htm

So I have decided to make the same thing with an Happ wheel a Logitech Driving force and an AMC 30A8.

This is my first test...


You can compare the two motors. The Happ have a 90V 1.5A motor with belt transmission.

The ratio with the wheel is 2/1. To compare the ratio of the G25 is 1/16...

So the FFB is very stong and smooth...

With the wheel I have added the Bluetiger paddle shifter. And I have inserted the system in a HIFI 2000 Box...

Test ingame with Rfactor Leo Bodnar plugin and CDTP mod. No sound to appreciate the silence...


Now I have changed the electronic of the Logitech Driving Force by the electronic of a F430 Thrustmaster and the system is ok too...

In an french arcade forum, Gameoover Aganyte has made a card to replace the AMC. You can see the topic here...

http://www.gamoover.net/Forums/index.php?topic=20242.0

I have not tested these card yet.

You can use too an immersion card that you can buy at GlobalVR to replace the Logitech or Thrustmaster electronic card and the amplifier The price of the card is 255$...

You can found the drivers for these card here...

http://www.immersion.com/products/touchsense-force-feedback/6000-series/electronics.html

But Immersion has announced the end of these card in december 2010...

So with a cost of approximatly maximum 500 $ (with a new Happ wheel 290$ for exemple, but mine cost 50$), you can have a FFB steering wheel 270° like a VPP...

For sure I have tested the F430 before open it and there is no comparaison with this two wheels. With the Happ system, no grind, FFB very accurate and precise. A very little bump is immediatly feel on the wheel, it's awesome...It's used in Bluetiger and Force Dynamic cockpits...

Another guy test now this system with a DFGT to have 900°. I'll inform you when it will be ok...

Hi Stef

I have recently bought a Happ wheel and i will be trying to make a Happ/logitech wheel to use in Iracing. I can't decide on which FFb wheel/PCB to use in the Happ. I have a G25 and really like the FFB feeling but i think interfacing it with the Happ is more difficult than using the Driving force EX because of the 900*rotation/optical sensor/twin motor output. So i was considering to use the EX PCB but i have a concern about the sensitivity and quality of the force feedback that the EX PCB can produce. The main thing that i want from the finished happ wheel is quality in force feedback feeling and sensitivity to grip changes not only strength and smoothness alone. Do you think that if i use the driving force EX PCB for the Happ wheel, it can produce a quality Force Feedback output?... as good as the G25 in your opinion?. Leaving the mechanical differences aside, do you think their is a difference between the way the driving force EX pcb and the G25 pcb or maybe the drivers deliver signals to produce the force feedback?.

Really looking forward to hearing about the 900* DFGT Happ wheel, maybe i will wait for this before i do anything.

I used Logitech Driving Force and now the Thrustmaster F430 FFB card, and the FFB is good as the G25. The Immersion FFB system is the same in each wheel. Only the motors and amplifier system are differents...Buy a used wheel and test it in 270° it's very good anyway...

And for the 900°, a guy in our french forum Racingfr.com is programming a system to have a FFB card for the Happ like the Leo Bodnar Card. With this open-source system, you can use the Happ without a commercial card wheel...

Just the card, an AMC and the Happ...

http://www.racingfr.com/forum/index.php?showtopic=40779&st=0

Before this system will be made, make your 270° tweak and let us see your system with screenshots or a video... ;)

Ok pics will come soon =), Today i received my happ! ok so now i am hunting for the AMC 30a8, and bidding on some DFEX wheels on ebay. If anybody knows where i can find a cheap AMC 30a8 please let me know.

This is crazy i found a AMC BE12A6E, brushless servo amplifier for $36, but the cheapest 30A8 i have found so far is $398. Ok this may take some time =/

I bought one for $35 + $45 shipping = £50. should be with me by next week...Thanks stef =)

hopefully their is no extra customs cost's when buying something from the U.S XD

soon the monster Happ will rise >;) ...... if i don't burn my house down first! hehehe

Lol, mine is not burned yet...Before going to holidays, little explications for the connexion.

- The DF Ex card must be powered by a 9-12V power supply.

- The AMC by a 24VDC minimum 100W.

- To not have interferences connect the metal part of the happ Wheel to the Ground of the 24 VDC Power supply.

- Before connect the AMC :

You can read his datasheet here.

http://www.a-m-c.com/download/datasheet/30a8.pdf

You must setup him in current mod (only sw3 and sw8 are On in the 30A8)

CCW all the potentiometers (12 turns, little click when it's ok), then turn the potentiometer two 6 turns.

Connect the AMC to the DFex card and the 2 power supplys, the AMC green led appears. Go to the windows Logitech control panel and setup centering spring center to 100%. Turn the potentiometer 3 carefuly, when the resistance is OK you can stop ...

And you can test Iracing... ;) Setup the game with FFB very low (read the Niels FFB topic to setup correctly the game...)

Hi stef, I have got almost everything!, just a couple of questions before assembly. Can i use the original 5k potentiometer in the Happ, or do i have to upgrade it? Your instruction was very detailed but i didn't understand why you have to turn the pot (ccw 12 turns, cw 6 turns) etc..? =/. i thought you just connect the 3 wires from logitech pcb to the pot on the happ steering shaft?
-------------------

For the Logitech PCB power supply I have found at home a charger, is this ok? :

input : AC 240V 50Hz
output : DC 8.4V 300ma/0.3a

-------------------

For the AMC ,I am looking carefully for the 24V 5-6a / 100w power supply because they are expensive and i am cheap..hehehe

edit: I have found a 24v dc 0.75a psu at home, can i use this just to test, then later i will buy 24v/5a/100w ??
-------------------

Next step.... I will connect everything and post a detailed photo, then if you say it is ok, i will power her up! =)

Great... :cool:

For the shaking, disable the "return to center" option in the Logitech controler board...

setup :

Strength 101%
Spring 0%
Damper 0%
Centering Spring 0% but enabled

In Iracing game FFB beetwen 10 and 60%, no more...

I already did these settings and it doesn't stop the shaking. Also when i turn up the centering spring in the drivers options, the wheel turns to the left or right instead of centering, also in rfactor usually i have the force feedback at -100 for g25 but now i have to put the slider to +100 for it to work normally. I think the forces are reversed. Or maybe this is normal for the EX :confused:

For the + 100 yes invert the motor connection...

For the oscilation it's ok because there is no friction with this wheel...It's the limit of the Logitech card made for the plastic wheel, small motor and lot of friction...But the happ with the immersion board makes that too... 2.03 in the video...


You use Rfactor too !!! So this is my controler.ini FFB setup...Use that whit the DRM mod and the Nordshleife 2008. Take the Ford Capri and enjoy...:D

In game FFB medium, force -30% (I use that with a 350 wheel, if you use a more small wheel decrease this rate), it's enough and it limits shaking in straight...

Yes i love Rfactor, thnx for the ini =). I also play Iracing Richard Burns Rally and LFS. Rfactor is not the best for tire physics but i always go back to it because the mods are such fun. My faviroutes are, Historix, F1 1988 by Carrera4, AE86 Club. Also the Leo Bodner plugin improves the feedback so much that it is like a new game. If you have Historix i highly recommend to delete the real feel and setup each car with Leo's plugin and a management tool like Leo's FFB Tuner. I'm sure you already know about these treasure's ;).
Centering Spring 0% but enabled

disable the "return to center" option in the Logitech controler board...
Click to expand...

Sorry to ask such a stupid question after all of your help and detailed instructions. i can't find the "return to center" option in the Logitech setting's. Is that different to centering spring?

----------------------------------------------------------
Edit: For Leo's FFB if you haven't already add a value of 0.3 - 0.5 (Castor) to give the centering forces of the steering. Also to improve sensitivity reduce: (road bump feeling) .

No, it's the same "centering spring"...

Agree with you I use too the Leo Bodnar Plugin,but for this mod the Rfactor FFB is better with this setup for me, I can feel all the small bumps of the road and when the front tyre loose grip when I brake etc...It's very precise. Have you tested it ?

Thanks for the info for the castor setup...

For Iracing and to no have clipping with the FFB I don't know if you use this program...

Thanks for the Program good sir, I haven't used that before i will check it out next time i go on Iracing. I need to make a shifter before Iracing will let me calibrate my controls and drive.

I have been working hard to try to stop my wheel shaking too much and vibrating. I don't mind the oscillating side to side to much (my old G25 did it) I also think it is normal for most FFB wheels because of the "spring and damper" method of producing FFB, but the problem is when the wheel is held centred and steady while stationary or while driving it produces violent random vibration around center position. It gets worse as the (Ref in gain) is increased so strong force feedback is not possible until this problem is solved. A dead zone doesn't seem to help either. I suspect that i am getting some interference from somewhere or maybe the pot is a problem:confused: I understand what you are saying about the lack of friction in the happ causing oscillation but it really doesn't feel right and it seems worse than any other happ example video that i have seen.Shark factor's wheel looks quite smooth and unless you are using different PCB your's looked very smooth as well in the video. Maybe i have made a mistake somewhere. Just a thought, maybe the happ potentiometer must be the same resistance to the original logitech to work properly?

The best solution i have found to reduce this Vibration and shaking is this Controller Setting:
___________________________________

Overall force feedback effects: 50

spring effect strength: 30

Damper effect strength: 60

Centering spring (enabled) : 0
___________________________________
Since the ffb works on a spring and damper principle i think the oscillating can be toned down by reducing either the spring or damper and having one lower than the other. I will keep trying. Do you think not having the buttons part of the PCB plugged in to the main PCB can cause button presses or interference? because i have not plugged in the buttons PCB.

P.S, today i was driving Iracing (Lotus 79') on my friends 3 monitor setup with high power PC and Maximum graphics using my old G25. I am speechless it was amazing, will have to post some vids =)))))

For the vibrations yes it's certainly interferences. I had that with the Logitech card before I ground the Happ (the big motor cause lots of interferences). I had too interferences in the buttons with random ,initialisations. Have you that in the control panel when you turn the wheel or test the FFB effects ? Curiously, no problem with the Thustmaster F430 card...

When holding the wheel at the center position and getting feedback wanting to rotate the wheel, it could be that you are using centering spring settings for FFB. Change your setup to not use the centering spring option and this should be taken care of.

To Jim, Centering spring is off (unchecked). The problem seems to be an interference of some kind.

To stef,

i did some testing today. I plugged in the Buttons to the main PCB and pressed some buttons, everything worked fine, no unusual button presses with or without the buttons connected. I did notice that the green LED on the wheel logitech EX flickered off when i was pressing buttons and using the wheel in rfactor. I guessed that my 12v 0.5a Power supply was not providing enough current for the pcb so i tested the original 24v 0.7a power supply whilst disconnecting the servo amplifier to protect it. the green light stayed on constant. So i connected another Power supply, this time 13v 0.7a. This time the green light stays on and only flickers slightly when driving. With the 13v supply the input signal to the servo amplifier must be stronger because the force feedback was stronger. But unfortunately the vibrations still remain. the ground wire is my next suspect, i have connected it from the Servo amplifier (PWR GRND) to a screw on the chassis of the Happ just above the potentiometer. I did a continuity test with the multi meter and it has continuity although sometimes not so clearly depending on how dirty the area is when i touch the probe.

Since the interference could be coming from the motor i was thinking to make a connection from Servo Amplifier (PWR GRND) to
(Motor -). Do you think this is safe to try ?. Lol i am really a noob with electronics =p

Edit : Another small issue, I think the motor is slightly stronger turning left than right. This phenomenon is reversed when the motor leads are swapped. Also when i let the wheel shake side to side the wheel turns left as it shakes.

For the interferences, your connection is good, and honestly I don't know if you can make this new connection without problems...I will ask in the french forum...

For the differents forces left right, turn the AMC potentiometer 4 to equilibrate the signal...

Edit : I have the response, don't make your connection solution or it will frie the AMC...

But to limit interferences connect the power ground ( - ) of the AMC with the power ground ( - ) of the logitech card...
