@MadMatt Ok, The system runs's on 2 comuters. 1 to play the game and 1 to control the seat. The I have some excellent software that is placed on both machines. The gaming machine uses this software to extract the data direct from the game and sends it to the other computer which then converts this into actions that can be controlled by an Arduino Uno microcontroller. This in turn is connected to a Monster Moto Shield motor controller that turns the 2 motors. On each shaft from the motors is a connected potentiometer that ruturns a signal to the Arduino that lets the computer know where the motor is positioned. This is all powered from an old PC Power supply unit.
Here is how it is wired up
On the software you can control which way the seat tips, how fast and how far.
@Alexx_88 The hardest part was getting the software working correctly, other than that it was just a bit welding and a lot of grinding. The cost could vary a lot. I already had 2 computers, the TV, the steering wheel. I bought the seat (£85) metal box section (£50) Motors & Gearboxes (£110) Electronics (£85) Other bits (£50).
So it cost me about £400 ish. If I total up everything I am using in this set up, which includes 2 computers, TV, surround Sound, Bass Shakers, Logitech G27, it would be something like £2000.
Money all well spent for many happy gaming hours. Today I managed 27 laps in the 7up Jordan 191 around Spa before the engine expired. Was a good work out, arms ache a bit now though
