Joystick Update - Throttle Box - Console - Steer - Rudder - Throttle - Schematics



Steering update

The last part was changing my basic controls to a universal USB unit. All the buttons and wiring were replaced.

The interface is the same as the Trottle Box, exists of a PIC18F4550 and is configured for 4 axis, 12 buttons and a 4 button HAT switch.



Throttle Box

While creating the AP units, I found a way to create an 8 axis, 8 button USB joystick interface. So, the sole for a big Trottle box was born!

Yet another big improvement to control four Throttles, Flaps, Spoilers, Mixture and Props with digitized sliders.

The interface exists of a PIC18F4550 and is configured for 8 axis and 8 buttons.



If you've seen the FS scenery page, you have read that I'm having fun flying around the world with FS. 

This piece of hardware makes it even more exciting and really give me control over the planes flying!


This is the main switch box and as such, connected to the game port of the PC. It holds the Throttle control, a rudder control for if the pedals are not connected and most of the buttons connectable to the game port. 

The steer / joystick and rudder pedals are connected to this unit.





The steer was the most exiting unit to create. The movements of it are mechanically connected to the potentiometers by fishing wire. 


Fly by wire, haha!


Ten buttons are situated on the steer itself. The four in the middle are the hatswitch. The brakes and parking brakes are the red buttons on top and the rest are for flaps control. 

The print on the back of the steer hold all the diodes needed for most of the buttons to work.



On my first rudder control, the pedals were mechanically connected to each other, if you pushed the left one down, the right one came up.

This is the second version and, oh boy, what an improvement!  Every peddle has his own potentiometer of 100k, which is later on changed to 50k with parallel connected resistors. 



This version has a nice side effect, If both peddals are back, the resistance to the PC is 50K, which means in the middle. If both pedals are forth, the resistance is also 50K. This feature makes it easy to adjust the pedals to the most neutral position of my feet.

The potentiometers are again connected to the pedals with fishing wire and a spring to compensate differences in distance. A full turn of the peddle turns the potentiometer exactly 270 degrees. 

The two resistors are connected in serial and are here drawn in back position.





After flying with 4 engine jet or propplanes, I thougt it became time to create a throttle box. This makes it possible to control every engine separately. Because the Gameport was allready used and I have no knowledge of USB ports, I searched for an extra gameport. After a while I found a unit, connectable to a USB port. Then the creation of the throttles was easy!


The potentiometers are connected in the same way as the "Coordination schematics" shown below.


Below are the drawings of how to connect such a device to the gameport.






Here some info of the connections and configuration I made.

Switch1 - Brakes

Switch2 - Parking brakes

Switch3 - Flaps step down

Switch4 - Flaps step up

Switch5 - Flaps down full

Switch6 - Flaps up full
