Ergonomic One Handed Keyboard and Joystick Using Artsey

P1180071-Enhanced-NR.jpg

In this project, we will create a one-handed ergonomic keyboard with a joystick, based on the open-source Artsey project. We identified the need for such a device when we discovered that existing one-handed keyboards for people with disabilities are often too expensive. Our final design is inspired by the natural form of the human hand, ensuring comfort and ease of use. As an open-source project, the device can also be adapted into a macro pad or customized for other functions.

Supplies

Supplies:

  1. KB2040
  2. KB2040 Pins
  3. 1N4148 Diodes
  4. Hook Up Wire
  5. Analog Joystick
  6. Jumper Wires
  7. Breadboard
  8. Cherry MX Style Switches
  9. Cherry MX Style Keycaps
  10. Switch Push Button
  11. Rubber Feet
  12. M3x Screws
  13. M3 Inserts
  14. PLA Filament


Tools:

  1. 3D Printer
  2. Soldering Iron
  3. Soldering Wire
  4. Wire Cutter
  5. Hex Key
  6. USB-C Cable

3D Print the Shell

This is the first step in the process of building this device.

First, download the files we attached.

Then, using the soldering iron, heat up the M3 inserts in order to melt them into place. Sand the parts if necessary.

Solder the Pins to the KB2040 Board

Now, get ready for soldering. Grab your soldering iron and some soldering wire. Begin by soldering the pins onto the KB2040 board. After that, connect all the components onto a breadboard.

Now we create the matrix.

Insert the keyboard switches into the shell and start by soldering the diodes onto the switches. We’ve included an image to guide you. After the diodes are in place, use a rigid wire to complete the matrix. Cut the wire to the correct lengths using a wire cutter, then solder it to the switches. Ensure the diodes and the wire do not touch each other.


Cut one end of the jumper wire and use the soldering iron to connect all the wires. Next, solder the jumper wires to the ends of the diodes and the cables.

This project is currently in progress, and unfortunately, we haven't been able to get the joystick to work yet. We encourage you to continue developing it and share your final results with us.

The joystick we used is the analog joystick. Attach the joystick to the shell using M3x screws. Connect it to the breadboard with jumper wires as shown.

Ensure the joystick moves freely. If it doesn't, sand the hole.

Now for the fun part: the code.

To flash the keyboard, you will need to download QMK MSYS and VS Code, which will help us flash the KB2040 with our code.

First, open QMK MSYS and type:

QMK new-keyboard


Then, you'll need to name your keyboard, and type enter.

Keyboard name? [insert-name-here]


Now select:

RP2040


Open VS Code

In your keyboard folder, create "keymap.c", and paste the following code:

// Copyright 2023 QMK
// SPDX-License-Identifier: GPL-2.0-or-later


#include QMK_KEYBOARD_H


//joystick config
joystick_config_t joystick_axes[JOYSTICK_AXES_COUNT] = {
  JOYSTICK_AXIS_IN(GP26, 0, 512, 1023),
  JOYSTICK_AXIS_IN(GP27, 0, 512, 1023)
};

Now save everything and go back to QMK MSYS.


In QMK MSYS, type:

qmk compile -kb your_keyboard_name -km defult

Replace 'your_keyboard_name' with your keyboard's name.

Finishing Touches

Now, after everything is soldered and connected, you can test the keyboard.

Attach the bottom cover to the shell using M3x screws. We recommend routing the cables neatly and ensuring they are not bent excessively.

We added rubber feet to the bottom to prevent the device from moving on the desk.

Insert any MX-style keycaps into the switches, and your keyboard is ready to use.

Connect it with a USB-C cable, and you are done. Enjoy! 😊

Creating this project involved a lot of experimentation. We tested various angles and button heights, tried different codes, and explored multiple shapes.

Here, you can see the process we went through. Remember, this is an open-source project, and you are welcome to continue developing and improving it.

We want to thank everyone who helped us with this project:

Enrico Bassi, @kapyuval, @electronegative
