Introduction: KSP Controller
this is a game controller (kerbal space program)
Step 1: Material:
-1 arduino pro micro
-a lot of momentary buttons (4NO joystick , led buttons ... )
-2 rotary encoders
-box to hold everything
- tools (drill, screwdrivers, soldering iron, ...)
-old USB keyboard *optional* (to add more buttons) (step5)
-and of course Kerbal Space Program
Step 2: Emplacement of Buttons
this step is very important because your controller must be ergonomic
I recommand you to make prototypes on cardboard to try differents emplacements of buttons
Step 3: Drill Holes
when you're happy with your buttons emplacement, make marks with a pencil and then drill holes to the correct diameter
Step 4: Soldering !
place the buttons in their respective holes and start wiring according to the schematic
Step 5: More Buttons
*this step is optional*
the number of buttons in a matrix is limited so there is a solutio:
open an old USB keyboard and take the PCB inside
the electronic card of a keyboard has several pins and when two pins are connected with a wire, the keyboard write a character so you can try all the combinaisons to found the characters " 1,2,3,4,5,6,7,8,volume+ and volume-"
then weld buttons to corresponding pins and if it works each button should write a number on your laptop.
Step 6: Wires
when all is welded, it's almost done
we have 3 USB cables:
-1 for arduino
-1 for the keyboard card
-1 for the lights supply
so the solution is to add an USB hub inside.
(the pink foam is here to insulate because my box is a metal box).
Step 7: Sketch
Step 8: Labels
print labels and stick them to the corresponding buttons.
Step 9: Assign
plug the controller at your computer and check with "joytokey" that all your buttons work
then launch KSP, go in settings,input and assign each button of your controller to a function.
