What is needed to...

... build a throttle system?
I plan to build such a console with the design of Dornier Do328.
It will contain throttle levers for both two engines, the propeller conditions for them (also two levers), a parking brake lever and a flap lever.

I believe I know how to construct that thing, and how to build the levers up, but I dunno, which hardware I need, to connect all the Potentiometers (I guess those are used for the levers?!) to my compuer.

There are numerous options for interfacing pots with the sim via USB, but this is what I'm going with:

More advice: make sure to use linear-taper pots, not audio-taper pots!

The trouble with audio-taper pots is that the voltage varies exponantially as you move the pot, whereas a linear-taper pot changes at a consistent rate from min to max... more like a real throttle mechanism.
