Do you need all the options on the MB? Gigabyte usually do the same board without raid etc for less. Can't see anything wrong at a glance but would check reviews and feedback, especially for power supply stress tests.
EDIT: SSD is a waste of money, $/GB is dropping fast, would suggest a big fat hd for storage and normal apps and a small ssd for OS and games etc.
EDIT2: GTX560 for 770.... ahh, what currency is that?

Not sure what you mean by 'releases their work', manufacturers holding the rights to vehicles or the artists holding the rights to their work?
They are only playing the same game every other tech company is being forced to play by a really screwed up patent system and playing it well in heart of the warzone of that game. Dinosaur's like IBM are too big to attack, they would be bigger 'patent trolls' than anyone if they where forced into a defensive position.
Google is and innovative company and patents make that hard. Everyone wants a piece of the android cake and are using patents to grab the biggest piece they can get, however the cake is a lie. Firstly google can drop android any time they please, the companies using it are familiar enough with its development cycle and its inner workings to maintain it as an open source project. Secondly, android is very closely linked to linux and IBM protects linux, anyone trying to claim a piece of android has to be very careful they aren't trying to claim a piece of linux too.
The XBox issue is just google waving its dick around by threatening a whole product line, unless they plan on releasing a gaming system to go head to head with directx then its worth nothing to them. Its the same with a lot of other patent issues google are involved in atm, they have very little to loose as they don't depend on hardware sales but not a whole lot to gain either. The only logical justification is an attack on the patent system but maybe there is a part of the picture we cant see from here.

Very minor issue, running VHPA on linux/wine and the sliders are hard to adjust, can only make coarse adjustments dragging them and scroll wheel is slow to respond (seconds). Guessing it's wine lazy with those widgets and I should be reporting it to wine :/
Thanks for a very useful app that just works (tm) with wine. Is it possible to add scripts or modify the parser to read/write configs for other sims? Hope that's not an impolite question, they should be improving their own games with useful tools like this.

What would folks think of paying for mods? Was thinking something like having to pay for extra track/car spaces to add mods to play online with no limitations offline. As already said, LFS is free to play with premium content and being able to add more content from 3rd parties is something I'd pay as much as S2 for but wouldnt want LFS online messed up servers full of all kinds of mods and different versions of each.

Doesn't go into much detail but covers the basics, microsoft can get licences for the patents anytime at 'reasonable terms'. Guess they will licence them at the last mo when they've milked as much publicity as possible. XBox hardware is getting old though, now microsoft has made a proper OS they can make the most of multicore and GPU processing power so maybe they will take the opportunity to paint google as 'the evil company that took away your xbox' while launching a replacement with far more power than the PS3. After seeing some of the changes in 7 would expect microsoft PC's and consoles to merge so the same games run on both and possibly integration with TV's (many have quite powerful hardware running embedded linux ATM).

Think the US economy wants a battle like that? IMHO google has intentionally started this battle to force patent reform.
Not sure how windows handles drivers for connected devices but with some 3g dongles this wont remove the driver even though it's uninstalled and removed from the list of installed software (vodafone dongles that also automatically install their vodafone network only driver when connected and will overwrite drivers for any other huawei dongles at the same time). Would suggest disconnecting > rebooting > removing driver > rebooting > connect device > install recommended driver, but the inner workings of windows are a mystery to me and if you've had success uninstalling with the device connected then its worth trying first.
Weird. Could be some kind of driver conflict, what OS btw, win7? At a guess the controller will 'just work' when plugged in without needing additional drivers, adding 3rd party drivers could cause confusion with multiple drivers trying to claim the device. Tweak utility's or profile managers could also cause similar problems.
They packet sniff USB communications and modify some packets, sometimes they get it wrong and modify stuff that has nothing to do with them. USB is a complicated protocol and includes a lot of stuff for hardware identification and configuration, usually this makes things 'just work' but in rare cases devices clash, unplugging everything but the device your having problems with should test for this.

+1, if you get the parts and put it together yourself you would save about 25%, more if you re-use things like your case, dvd etc. For gaming would suggest only the faster RAM (1600mhz) and a small solid state drive (about 60-70 euro).
+1 It would be interesting to see how LFS would incorporate mods though, most of the issues with mods in other games is due to hack and slash methods of adding them, a proper system for adding mods would include checks to filter out anything badly done. /me longs for the day when I can go to Audi's site and pay maybe 20 euro for a copy of this years Le Mans car that will work with any up to date and respectable game and maybe 50 euro for an exact model of this years Le Mans circuit to race it on, half that for last years and any amount of mod community cars and tracks for free and they will all just work(tm).
Try on a different PC or a different installation (linux live CD would work ok if you cant get to another win PC) to test is it a hardware or software problem.
I've been checking through a few other options, chains wont go small enough for the motor pinion's. Multi row v belts might do it, they would need to be quite wide because of the small pinions and I'm not sure what's available. 97mm dia x 3.142 (pi) = 304.774mm circumference / 2.5mm pitch = 121.9096 teeth (near as damnit to 122) / 10 (number of teeth on motor pinion) = 12.2 to 1 ratio. Still a long way from 16 to 1, I really doubt it would do any harm trying that but there is a risk of damaging the motors or driver circuits. The risk would be small though as everything will be designed to work with the motors stalled, doesn't mater what ratio it is if they're not turning.
EDIT: Maybe PM with this if no one else interested, save filling up the forum with posts full of numbers

I make that about 16/1, smallest 2.5mm pitch pinion listed if 10 teeth so would need 160 teeth on the main pulley to match which equals 128mm dia :/ If a pully was made 92mm dia (to leave clearance for belt) it would have 115 teeth so 11.5 to 1 ratio, that's a big difference, response would be a lot faster but force would be reduced by about 30% and it wouldn't be good for the motors and amplification circuitry. If you can source 8 tooth pinions the ratio could be got fairly close, about 14.5 to 1. Been searching for alternatives, there are 1 and 2mm pitch options but cant see anything that would go straight onto the motor shafts, will dig into it a bit more later.
Know you don't rate linux much but the audio subsystems and realtime kernel should make it a seriously good audio production platform. Plenty of tools for this kind of thing but not much with the finish of commercial software.
Lol, If you want to see how much truth is in the 'war on drugs' check Afghanistan's opium production before and after the place was invaded. Holland has by far the most responsible and aware folks I have ever met regarding drugs, taking away the 'breakin the law' aspect there seems to have had a very positive effect.
Link works but wants me to log in, can you change permissions? Motors only need the connections reversing, sensor is fine
Do you mean the gear will have to be cut off the main shaft in the g25, its not bolted/screwed on?
Seen that on ebay from time to time, engineering plastics are plenty strong enough and are cheaper than aluminium.
I can but the teeth take up a lot of time, could do one for a hell of a lot less than $200 though. May be worth checking companies selling that kind of thing near you, even ones with silly prices, as they can often do a reasonable quote for that kind of thing with CNC machines tooled for the job.
Hopefully the pinions you get will have a grub screw for tightening, the pinions on the motors are probably pressed on and can be tricky to remove, worth getting a drift if you don't have one.
Once you have the motor mountings decided its easy enough to figure out the belt length, the site you linked to probably has a calculator for it. Count teeth to get the ratio's and figure out how many you need on the main pulley to match your pinion options, 100 teeth at 2.5mm pitch is less than 80mm, get it as big as you can to suit a pinion to reduce strain on the belt and keep noise down. Think there are g25 internal photo's in some forum threads, will have a look later.
So where do Apple get their boards made? And there are no lack of crappy apps for iOS unless fart noise generators are your kind of thing. Games companies seem to be paying a lot more attention to iOS and android than PC's at the moment, android has issues because its not on set hardware but that never stopped the PC industry. Surprised so few games run on mac though, it has the same benefit's.
Jumping could be a problem due to the angle the belt is driven at, cam belts cover at least 90 degrees of the pulley so the teeth are effectively pulled hard together, you have about 45 degrees of contact each side so belt tension would need to be doubled to get the same kind engagement. Doubt it would be a problem but if there is an easy way around it then its a potential problem avoided.
What way is your offset? Could a drilled aluminium or acetal plate line things up or is it the opposite direction where you would need a dish shaped mounting for alignment? Would suggest acetal or even plywood for that, both are strong enough for what your doing and a lot easier to hand work than aluminium. If you need an odd shaped mounting made I could turn one out and put it in the post, I have 80mm dia acetal and its really fast stuff to machine, would probably work out about 10-20 euro +post depending on complexity.

That's what many press articles are saying, strangely they all started saying it about the same time, often from jurno's that contribute very few articles. Maybe that really is the opinion of the majority of dev's but I'd be sceptical, too many dirty tricks in the name of promotion on the net these days. Same with this vulnerability, it's almost trivial compared to the amount of attacks on windows but news of it is all over the press, a good wake up call for the mochachino drinkers but its blown way out of proportion.
Usual problem with replacing gears with belt is getting the ratio's low enough, you may find you need a huge output pulley to get a low enough ration with the smallest available pinion. 2.5x6 is a little small, it should handle the motor torque ok but you could have double that torque with inertia, belts are cheap though (put a second one on the shaft before assembly so if it does strip you wont have to take the whole thing apart to fit a new one). Good luck with it, should be a big improvement.
EDIT: 2 belts would be better, the single belt could jump out of engagement fairly easily.

That where the wheel comes in usefull
You can do the whole thing without using the physics engine, the maths are simple enough, but it has to link in with the environment somewhere and its as well to have it the option of rotating components affecting the vehicle dynamics from the beginning plus most physics engines built in functions simplify the maths.
Throttle opening gives a percentage of torque derived from RPM, clutch allows a percentage of torque from engine to gearbox, torque is multiplied by gear ratio, resulting torque is divided by final drive, split by the diff and sent to the wheels. Sounds like this is the point your connecting to the physics engine, the next physics clock should give you the new wheel speeds to run the whole lot back and get the new engine RPM.
Throttle opening isn't simply a torque percentage, it should be a torque curve of its own but that's an almost perpetual situation as you would need to write an engine simulator, simply using the percentage of torque and max RPM would be enough to get started, negative torque output after max RPM otherwise no engine braking. If engine inertia isn't applied then you get no progression, the engine either sits at max RPM or syncs with wheel speed, when inertia is calculated it can be taken into account with RPM to modify clutch output. Then the physics engine gets into a big fight with your inertia calcs and throws the whole truck in the air

There isn't much to the drivetrain that's not covered in other game components, the speeds are just basic maths and the forces are handled by the physics engine the same way any components mass and direction are handled. Any open source vehicle sim's code will give good examples, there are many, I found vdrift's code base easy to get to grips with YMMV.
EDIT. If you mean engine characteristics its often done with the torque/rpm values for various rpm in a vehicle config file, think LFS uses a formula to produce a torque curve though.
