The enclosure is made of two printed parts (base and top) wich will clip together .

Select the right design, fit to your needs

• WHEELCHAIR COMPATIBILITY

---

For a  6.4 mm diameter joybar = Power wheelchair with Rnet or PRIDE electronic : Permobil, Ottobock, Sunrise, Levo.

select : base A_6.4 mm hole.stl

For a 5mm diameter joybar = Power wheelchair with Linx electronic (Invacare)

select : base B_5mm hole.stl

• HANDLE

For standard needs  (standard joystick handle) : select top_joystick.stl

If you need a ball to facilitate gripping select : select top_ball.stl   

You can also design a specific handle adapted to your need (ergonomic, esthetic) and mix it to this base : top_flat.stl

Material :

We use ABS on a Zortrax M200 for  its resistance and its functional prototyping properties.

It should work well with other plastic types, depending of the 3D printers you use.

For a standard print, we have good result with this  parameters :

Infill = 30 % of

Layers thickness = 0.19mm

No support added

Printing time : 3h48

Material usage : 14.6 m, 35g

• Bring together the different components

• Individually prepare the components :

Solder headers on the trinket m0

Cut off the four no use headers of the SEN-MPU6050 ( XDA, XCL, ADO, INT)

Bend the four headers (VCC, GND, SCL,SDA) at a 90 degree angle

• Insert the components on the PCB, following one board printed indications

Switches

MPU6050

Trinket M0

• Soldering

Turn the PCB

Solder the different components pins

Cut of the excess lenght of the pin

Place  button caps on switches

Insert PCB onto the enclosure

Place the top part on base part

Push it to clip the two parts

Select the right program either you need a game stick or a mouse :

• For a game stick :
  

Select the arduino sketch in the files project : Joytostick_TRINKET_M0_v2.ino

Set Up arduino IDE, see ADFRUIT's Trinket Information and follow instructions https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/arduino-ide-setup

Download and install theses libraries to the arduino IDE:

MPU6050_tockn by tockn

Joystick Library for Adafruit TinyUSB by gdsports

Connect the usb cable  : Micro B Male on the Trinket and USB 2.0  Male in the PC

Be sure to set the USB Stack to TinyUSB

Upload the sketch to the Trinket

Check it proper functionning by using Gamepad tester website.

The values corresponding to AXIS 0 and AXIS 1 will vary according to the movements of the device, it means it works.

All that remains before playing is to install the box on a wheelchair controller

• For a mouse :
  

Select the arduino sketch in the files project : Joytomouse_TRINKET_M0_v2.ino

Download the MPU6050_light library in the library manager of the arduino software.

Upload the program to the Trinket

We can check its proper functioning by connecting the joystick to a PC (windows, linux, MACOS, or a smartphone)

The device is recognized as a mouse device and works without further manipulation. The movements of the box move the cursor on the screen and the buttons correspond to left and right clicks.
