Build a Hall Effect Joystick for my VRS F/A-18E Superbug


My intention is to make a practical joystick , and a "cockpit", not necessarily visually realistic, just works for me. As long both work and feel good I will be happy.
I just want to fly the aircraft.

This is my current setup. The joystick is a Thrustmaster T.Flight Hotas X with my own designed hall effect Ailerons / Elevators sensors, not too good. There is a
fault in my design that creates a dead spot around the center position of both the Ailerons / Elevators axis's. This dead spot can be seen with the
program DIView.exe. (DIView download) as well as flying the aircraft.

My latest design hall effect sensors are balanced about the center position of the joystick. The slightest movement of an axis will change the numbers. See the
graph below. The joystick is 406 mm tall from the gimble center so 1 Deg. = 7 mm at the top of the stick.

You will note that if you do this sum (63260-2607)/2 = 30326.5. The center of the movement. If you look at the graph you will see 32623 as the center of movement.
This is because the Y axis of the hall effect sensor (Honeywell Type SS496A1) was 0.12 mm off center. My mistake as is the X axis which is -2.86 mm instead -3.0 mm. Both will be adjustable in my new sensor design. (The axis's I refer to , X and Y, are the coordinates of my milling machine and not for the actual joystick gimble axis's or the Lotus123 spread sheet graph).

This is the hall effect test setup that produced these numbers.

A couple of pictures of what I have now. It is worth noting that I have found that FSX will not run 6 individual monitors only 4. The top 3 monitors are part of an
eye infinity group so my Windows 7 - 64 bit believes that the top three monitors are 1 screen as does FSX. My Computer has 3 off Sapphire Radeon HD
7790 2gB Edition graphics cards with a Club 3D MST hub plugged into a data port in one of the graphic cards. The Club hub runs the top 3 monitors.
