Great idea, I've thought of something like that, too. My latest idea
would be to buy a cheap 4-axis USB joystick (can be had for less than
GBP20 each), rip it up, and you'll have all the USB electronics you
need. Buy more of these if you need more axes (for multiple throttles,
toebrakes, etc.). Remember: the price you pay for a joystick is for
the mechanics, the electronics is almost free, so you can expect
pretty good electronics even from the cheapest models.

You can always try analogue first, but you'll have a problem with the
number of axes you need. USB also has the big advantage that it is
electrically robust, so you don't run into problems with your rudder
cable picking up noise from the rest of your computer, mobile phone,
etc. If you want to program a USB chip, it shouldn't be too difficult,
since the HID endpoint specifications are available (I think), so you
know exactly what you have to code. The Cypress EZ-USB series might be
an easy solution: you write your endpoint code in 8051 assembly or C.
The rip-up-a-joystick solution is probably easier and cheaper, though.
