Re: USB Joystick to DB15

The problem is that the OI measures voltage from 0 to 5 volts, and turns it into a number from 0-255. You get a variable voltage using a potentiometer, which is what you'll find in the kit-provided joysticks. The problem with modern joysticks is that they give a digital output, sending pulses on a wire. The OI cannot process this sort of signal. Even if you converted the connector to DB9, you'd still be getting the same sort of signal. Your joystick probably uses analog values to generate the digital signals, so if you're feeling courageous, you could open up the joystick, bypass much of the internal circuitry, and wire the potentiometers directly to the proper pins on a DB15 connector. If your joystick uses some fancier sort of sensor (optical, perhaps), it might be a little different. The point is, it's likely that you can get your joystick to work with the OI, but the rewiring you'd have to do would be internal.
