How to Build a Custom Mechanical Keyboard: A Beginner’s Guide

Building your own custom mechanical keyboard is a rewarding project that lets you create a typing tool tailored precisely to your preferences. Whether you’re looking for a specific feel, sound, or aesthetic, a custom build can deliver exactly what you want. Here’s a step-by-step guide to help you through the process, along with some popular websites where you can purchase the necessary components.

Step 1: Gather Your Components and Tools

Before starting, ensure you have all the necessary parts and tools:

• Keyboard Case: Choose based on material (plastic, aluminum, acrylic, etc.) and mounting style (tray, top, gasket, etc.).
• PCB (Printed Circuit Board): The brain of your keyboard that connects switches to your computer.
• Switches: Decide between linear, tactile, or clicky switches depending on your typing preferences.
• Keycaps: The visible part of your keyboard, available in various materials and designs.
• Stabilizers: Essential for larger keys like Space, Shift, and Enter to prevent wobbling.
• Mounting Plate: Adds structure and stability to your keyboard, holding the switches in place.
• Soldering Tools: If you’re using a non-hot-swappable PCB, you’ll need a soldering iron, solder, and a desoldering pump.
• Additional Tools: Screwdrivers, tweezers, keycap and switch pullers, and a multimeter for testing connections.

Popular Retailers:

• Drop: Known for high-quality keycaps, switches, and keyboard kits.
• KBDfans: Offers a wide selection of cases, PCBs, and other custom keyboard components.
• MechanicalKeyboards.com: Sells a variety of keyboard parts, including keycaps, switches, and full kits.
• NovelKeys: Specializes in switches, keycaps, and custom keyboard kits.
• Switches: Provides a broad selection of switches and related components.

Step 2: Prepare Your Workspace

Set up a clean, organized workspace with proper ventilation if you’ll be soldering. A non-conductive work mat can help protect your components.

Step 3: Lubricate the Switches (Optional)

For a smoother typing experience, consider lubing your switches. This process can be time-consuming but can significantly improve the feel and sound of your keyboard.

Step 4: Test the PCB

Before assembling your keyboard, it’s crucial to test the PCB. Connect it to your computer and use a pair of tweezers to short the contacts where each switch will go, ensuring each key registers correctly.

Step 5: Install the Stabilizers

Assemble your stabilizers if they come in parts. Then, attach them to the PCB, making sure they are secure and rattle-free. Screw-in stabilizers are preferred for better stability.

Step 6: Mount the PCB and Plate

Depending on your case and plate, mount the PCB to the case. For most builds, you’ll place the plate over the PCB and secure it using the provided screws. Ensure everything aligns correctly.

Step 7: Install the Switches

If you’re using a hot-swappable PCB, simply snap the switches into place. For soldered builds, place each switch in its respective position and solder the pins to the PCB. Double-check that all switches are fully seated and soldered correctly.

Step 8: Install Keycaps

Once all switches are in place, install the keycaps. Start with the larger keys that use stabilizers to ensure they function correctly. Then, proceed to install the rest of the keycaps, taking care to align them properly.

Step 9: Assemble the Case

With all internal components in place, close up the case. Make sure everything is snug and secure, and that no cables or components are pinched.

Step 10: Test Your Keyboard

Plug your assembled keyboard into your computer and run a key tester program to ensure all keys function correctly. If any keys don’t register, check the corresponding switch and solder joint.

Step 11: Customize Firmware (Optional)

If your keyboard supports it, you can customize key functions, lighting, and macros using QMK or similar firmware. This allows for deeper customization of your typing experience.

Step 12: Final Touches and Enjoy!

Once everything is assembled and tested, give your keyboard a final inspection. Make any necessary adjustments, and then enjoy your custom mechanical keyboard, uniquely built for your typing pleasure!

Building a custom mechanical keyboard requires patience, precision, and a bit of creativity. By following these steps and utilizing the retailers mentioned, you can create a keyboard that not only looks great but feels and sounds exactly how you want it to. Happy building!
