Dual X Joystick

Joysticks are very  hard to find these days. This is a simple Dual X (or dual Y) joystick that

you can easily construct for a few dollars.

Although the two 10KLIN control Potemtiometers are driven by the same axis, their  respective ranges

can be set individually by two other 10KLIN attenuation potemtiometers.

Also, it is possible to set the pots to different polarities...According to the position of the two DPST toggle

switches, You can, for example, set the Xa joystick to +V and the Xb joystick to -V.
