It should at least wiggle or trying to fry itself :P
Are you sure your parallel port does what it's supposed to do (and you got the right pin)?
You might need a driver to access the parallel port, like dlportio. You only need to install it, you don't need to use it in your software.
it will probably work, but it's really cpu intensive to do. Windows (and any other non-realtime os) isn't made for +/- 0.05 ms accuracy, so your servo will not move very smooth.
a servo has a 3 wire connector. +5 (red), ground (black) and signal (usually white). The signal wire goes to pin 2 of your parallel port. If you write a 1 to the parallel port it goes high, 0 and ik will go low. For power, you can use the internal power supply from your pc. If you use an external power brick or battery, don't forget do connect the ground from the external power source to the ground of your pc.
Do not, i repeat, do not use an USB connector for power. It can't provide enough current to drive a servo. You will get an overcurrent warning.
the high part should be between 1 and 2 ms. 1.5ms is the center position. Some servos accept a wider range, like 0.6 - 2.4 ms. 1.5 is always the center position.
You can use timer1 and ocr1a / ocr1b on the attiny to drive two servos. Take a look at this page.
You don't need an external oscillator, the internal one (1MHz default, 8 if you disable the CKDIV8 fuse) will work just fine.
edit: or do you mean the servos built into a car dashboard module? As far as i know there isn't a universal way to connect one of those. On modern cars they are controlled by the onboard computer, without documentation it would be very hard to use one of those. Old cars get their tacho signal from the ignition system or alternator, that should be a lot easier.
almost 5 euro per board here.
But there's no warranty and some displays are badly damaged or broken. They are easy to fix though, but the led blocks are a bit hard to find (and you'll probably want to replace all of them if you need to replace one, since the new blocks are much brighter).
Well, those HD44780 displays can be connected directly to a parallel port. You'll only need an extra variable resistor for the display contrast, and an optional transistor if you want to be able to switch the backlight on and off. You'll also need a power supply, you can use an USB port for that.
Using USB for interfacing isn't easy.
Sure you can. But you'll need to build a display driver circuit, since the built-in circuit (usually a single-chip alarm clock + display driver chip) probably doesn't provide a way to show your own data.
it's more practical to just buy a HD44780 compatible display, they are really cheap and easy to use.
Or get some 7 segment displays, BCD decoders and a bunch of resistors and build your own display like this.
Played it about a year ago, but it was pretty crappy. Really bad lag and massive synchronisation problems (2 drivers in a car, stuff like that).
This is the result of running a server for a few weeks: Banlist. It doesn't even include everything, it's only minigun use (since it wasn't possible to use that without cheating).
Some setups do have a very long 1st gear indeed.
However, the default setup on the GTI looks pretty accurate. The top speed in 1st gear is just above 60KM/h, about the same as a Honda Civic type R.
I think the problem lies in the fact that you can't really feel the clutch grabbing and compared to a real road car, the clutch in LFS is more "sticky" (more like a racing clutch).

You should delete every .exe you can find too, they might contain virusses.
Well if you want low memory usage and high speed, you should use plain C(++), not a language that uses some sort of virtual machine.
But don't come back crying you've just made a massive memory leak and can't find it
