As Engineering Video

My controller is a piece of adaptive technology for Diplegia and Quadriplegia that is meant for keyboard inputs. It has a joystick with an easy grip and dual buttons for Diplegia and a Headmount with a mouthpiece and two pedals for Quadriplegia, I created this because controllers that have inputs that are accessed using your mouth have always fascinated me and I felt like it was the easiest option for someone with no arm movement. The pedals are accessible with small foot or leg movements, and the joystick and dual buttons require little precision.

Supplies

Joystick Foundation

1. Cut out 4 equal size squares and one larger square for the base.

Rubber Bands

2. Attach 4 brass pins with rubber bands onto the largest square.

Grip

3. Cut the tennis ball in half.

4. Glue foam tubing on top to make the grip.

Joystick Main

5. Attach the tennis ball to the wooden circle.

6. Glue four wooden 90-degree angle hooks to each edge.

7. Tape down strips of copper wire pointing out from 4 edges on the wooden hooks.

Walls and Finish

8. Glue all four walls to the base.

9. Glue down the CAD joystick mount in the center.

10. Attach the joystick main by mounting it and then putting the rubber bands on the hooks.

Dual Buttons Foam Core

11. Cut out a rectangle then cut out two smaller ones that are about half the area of the larger one.

12. Glue down six springs in the middle of the large rectangle.

13. Then glue both smaller rectangles together.

14. Add tinfoil to both sides with the copper wire sticking outward in the same direction from under the tin foil.

15. Do the same as step fourteen to the larger rectangle.

Pedals Foam Core

16. Cut out four evenly sized rectangles.

Pedal Springs

17. Glue down two springs to two of the rectangles

18. Add a couple of layers of tin foil in the center of the springs with a piece of copper wire coming out of it.

Pedals Wire

19. On the other two rectangles poke two screws into the foam core and attach copper wire between them.

Pedals Finish

20. Attach an arced piece of copper wire to the screws on both rectangles.

21. Align the short edge of each top and bottom rectangle and make sure the screws fit into the springs

22.Tape edges together

Quadriplegia Frame

23. Create a wooden rectangular frame.

24. Wrap copper tape around the middle of each side

25. Attach two wooden support beams to the bottom of the frame. (Make sure they can rest on your chest while the frame is still in front of your face.)

Wiring and Tube

26. Wrap copper wire around the tape so you can attach the alligator clips later.

27. Glue down a foam tube under the tape facing the same direction as the supports. (This will wrap around your neck so adjust the length based on the frame and supports so that it still sits in front of your face.)

28. Make a wooden beam that when pressed against your mouth aligns with the copper tape.

29. Attach an equal-length cross on the top of the beam.

30. Wrap copper wire along the beam and around the cross so that it protrudes from all four sides.

Putting It All Together

31. Cut off a 1-2 inch portion of the foam tube.

32. Make two angled wooden beams that when attached to the middle of the frame still have room in the middle to glue the tube in between.

33. Slide the wooden beam through the foam tube and attach the CAD mouthpiece.
