I'm working on making an F-15 Simulator for my home. I need some help however. All I want is to have switches in the cockpit preform actions in the simulator program. I figured I might bbe able to take a keyboard apart, and solder contacts to the keys which lead to switches. I can then program them accordingly. I have a problem with this idea though, a keyboard repeats its commands when holding a key. I want the keyboard to only send out one command every time i flick a switch. Any information on how to do this would be greatly appreciated.

Rather than hacking a keyboard, try hacking a game controller. Hacking keyboard is workable, but you've already discovered one of the major headaches of that particular approach. People have come up with various solutions. The easiest is just using momentary switches. Another places a capacitor in series with the coil of a relay. The switch applies power to the relay through the cap. The relay only closes until the cap charges up. It works but the cost adds up. If you're only interfacing a few switches, a hacked game controller works well and doesn't have the repeating key problem. If you want lots of switches, you're better off buying an interface designed for the task. You can use a keyboard emulator from Hagstrom Electronics, or you can use one the excellent input modules from Beta Innovations. There are also devices called Phidgets (from a company called Phidgets, believe it or not) for interfacing. My personal favorite is a DIY approach based on PIC micro controllers.Have you seen Gene Buckle's F-15 sim? www.f15sim.comMikewww.mikesflightdeck.comwww.mikesflightdeckbooks.com
