GaryMcT's 2-player generic control panel layout

GaryMcT:
I have to think about it.  What makes it crazy hard is that with a gamepad you have access to both a stick and multiple buttons with a single hand.  May require a stick with buttons to work for a lot of games.

I think they are potentiometers

happ's analog joysticks have either 5k or 100k pots though it says "Optional pot. amplifier PC board allows variable output from potentiometer"

I have no idea how that "k" relates to volts ???

The K on a potentiometer is the resistive value in kilo-ohms (1000's of ohms) of the device. Even though resistors are current limiting devices, it's normal to see a change in the voltage across the resistor/potentiometer as the resistance changes.

I'm an electronics newby.  Is it likely that the circuit in the x360 controller is reading the voltage change, or the resistance change when reading the analog stick?

I'm not an expert (I just dabble in electronics), so someone please correct me if I'm wrong...

It's probably feeding the pot(s) with a regulated input (precisely fixed voltage), then measuring the output through an analog-to-digital converter (ADC). The return voltage will drop as the resistance increases.

yeah, I was thinking 4 buttons (2 trigger and 2 thumb) on each flightstick and possibly a d-pad on one

and just the 3 admin buttons on the actual panel

If I were doing this on a large enough control panel, I'd probably also want to put some regular buttons on the surface for games that don't use the right stick.  I think the thing that hurts me with gamepads is having to "claw" my hands.  I think a flight stick might actually have the same problem for me unfortunately.

I'm pleasantly surprised that playing arcade games with a ball-top U360 and a bunch of buttons is really ergonomic for me and I doesn't hurt me nearly as much as playing an FPS on a PC with a mouse and keyboard (mouse hand kills me) or playing on an X360 controller. :)

ahh, that's easy enough
