A big thank you to all who replied about the specs of the power supply
for the Guillemot Ferrari Force Feedback Wheel.
Unfortunately, the original power supply of 20V, 750 mA output is very
difficult to come by.
The closest I have seen is an 18V 1.1A (1100ma) output. I'm not sure
whether this would "fry" the electonic components in the wheel or not.
Would anyone have any idea about this.
In the meantime, I am using my scanner's power supply which is a 15V
1000 mA output. The wheel seems to work OK, but I'm not sure how strong
the forces should be.
regards
Shivy

Well, I can't see how putting 18V in instead of 20V will fry the
components. Should work fine, especially as you say the 15V one works
ok.

These cheap power supplies probably work on a +/- 10% variance anyway. The
amperage of a power supply is what it's capable of providing without burning
up. It's drawn from it, not pushing it out into the device. In other words,
the power supply must be capable of providing at least the amount of amps
required by the device (wheel). If the device is expecting 20 volts and only
receiving 18, it might draw more amperage than specified, but I'd think that
the extra 350mA that your transformer is supplying should be sufficient. At
any rate, it wouldn't harm the wheel directly, but theoretically you could
burn out the power supply. Not too likely in your case. The actual
electronics in your wheel are pretty well regulated and drop down the
voltage anyway. The motor is the only thing using 20 volts. Could running
an 18v power supply make the FF weaker? Yes, probably a little. Will you
notice it? Probably not.

Thanks Slot,
It all makes sense now. I will definetly go and buy the 18V 1.1Amp
supply this weekend and test it. The guy at the shop said that cheapie
supplies (�14.99) usually have a 10% variance so I guess this one
should work fine especially if it has another 350mA in reserve
However, I can also get a regulated 24V 1.1 Amp supply (for the same
price), but maybe this could be too risky considering the voltage is
too much (especially if there could be a 10% variance) again, any
thoughts regarding this one?
Final question, I read someone else's usenet article and they said that
when they have the forces set up to max, then in games like GPL and NFS
the wheel can literally be ripped from ones hand. Is this so or just an
exageration?
In the meantime, great website! Will you be putting a GP3 section up,
aswell, in the game settings page?
cheers

a chance to put anything up for GP3. I think it's pretty well covered in
other places, except for the part about FF strength being tied into the
wheel 'steering sensitivity' setup. Plus, I'm getting behind on other
articles that need finishing.
I think I'd stay away from a 24v power supply. I'm not saying it would cause
problems for sure, but I don't think I'd be willing to risk it myself.

Yes, I guess I'd agree with you about GP3. I have to admitt, I have not
tried that 'steering sensitivity setting yet'. Gotta wait until the
weekend to try it.... shocking ;-)
Anyway, regarding the 24v supply, I agree.. it's not worth the risk.
However, please correct me if I'm wrong about the following.
I've just noticed that my power supply for my laptop has an output of
19V, 3.16A. So in theory, I could connect this supply upto the wheel,
eventhough the amperage is 3.16A. Effectively, the wheel will only draw
out 750mA plus anything extra to compensate for the difference in
voltage (1 volt in this case). Having that extra current of 2.41A
(3.16A-0.75A) should not fry the wheel. Is my logic here correct?
Thanks again .. Shivy
