Surely this project is very interesting, but the electronic part will be the easy one, thanks to these USB controllers. Nevertheless, there is still the question of the control handles.
Sam's project is impressive, but it requires room, skills, time and patience. All these virtues (yes!) are necessary due to the high cost of the potentiometer mechanics.
I bought 5 years ago a Morse control, made of a €10 pot, plus plastic/Alu casing, 4 LEDs at €0.05, one micro pushbutton, reduction gears, at a price of €475 (with VAT)... Vetus, Commander, Rexroth, Kobelt and other ones were as expensive if not much more. If it can be accepted for a ships' control, I think spending as much money for a luxury potientometer is overkill, even a very nice one.
I would greatly appreciate if the author gave an idea of where to find, or how he himself built these controls.
