Introduction

This tutorial will guide you through the process of creating a DIY 87-key macro keyboard, perfect for those who need extensive macro functionality in their keyboard setup. Whether you're a gamer, a video editor, or simply someone who uses many keyboard shortcuts, this customized keyboard will enhance your productivity and streamline your workflow.

Step 1: Gather Your Materials

To start your DIY project, you'll need to collect all the necessary components and tools.

• Keyboard Base: An 87-key mechanical keyboard (preferably one that can be disassembled).
• Switches: Choose your preferred mechanical switches.
• Keycaps: 87 matching keycaps (check the provided link for images).
• Microcontroller: A compatible microcontroller to handle the macros.
• Software: Install AutoHotKey and Luamacros.
• USB Cable: For connecting your keyboard to your computer.
• Soldering Kit: If your keyboard requires soldering.

Step 2: Disassemble the Keyboard

Carefully open your keyboard to access the internal components.

• Remove all keycaps using a keycap puller.
• Unscrew the back casing and gently lift it off.
• Disconnect the PCB (printed circuit board) from the casing.

Step 3: Connect the Microcontroller

Integrate the microcontroller to enable macro functionality.

• Position the microcontroller on the PCB.
• Follow the wiring diagram provided in the GitHub link to connect the microcontroller to the switches.
• If soldering is required, ensure a steady hand and clean connections.

Step 4: Install Software

Set up the necessary software to configure your macros.

• Install AutoHotKey from the official website.
• Download and install Luamacros from the provided link.
• Customize your macros using the Lua scripting language or AutoHotKey scripts.

Example code snippet for AutoHotKey:

; Example Macro
^j:: ; Ctrl + J
Send, Hello World!
return

Step 5: Customize Your Key Layout

Design your key layout based on your preferences.

• Use the provided keycap images as a reference for aesthetics.
• Decide on the functions for each of the 87 keys.
• Create a layout map to help visualize your macro assignments.

Step 6: Test Your Keyboard

Before final assembly, ensure everything works as expected.

• Plug the keyboard into your computer.
• Test each key to confirm that the macros operate correctly.
• Make adjustments to the key assignments as necessary.

Step 7: Final Assembly

Once testing is complete, reassemble your keyboard.

• Carefully place the PCB back into the casing.
• Screw the casing back together.
• Replace all the keycaps securely.

Conclusion

Congratulations on building your own 87-key macro keyboard! This customized keyboard not only offers extensive functionality but also enhances your overall productivity. As a next step, explore more complex macro setups and consider sharing your setup with the community. Happy typing!
