Creating a custom mechanical keyboard is a relatively simple but rewarding process. With just a few components and some basic tools, you can design and build a keyboard tailored to your preferences. This comprehensive guide would provide a step-by-step approach to creating your first custom mechanical keyboard.
The first decision you need to make when building your custom mechanical keyboard is the layout. The layout includes the arrangement of keys and the overall size of the board. The primary types of keyboard layouts include full-size, tenkeyless (TKL), 75%, 65%, and 60%. A full-size keyboard includes all standard keys, including the function and number pad. Reducing the size eliminates certain keys; for instance, a TKL layout removes the number pad while a 60% layout would further remove function row and navigation keys, reducing it to a very portable format.
Your choice of layout should be dictated by how you intend to use your keyboard. If your work involves extensive data entry, you might find the number pad quite useful. Conversely, if you’re a gamer or need more desk real estate, a smaller footprint keyboard might be more appropriate. Remember, this is your creation, so choose the layout that suits your needs and preferences best.
Next is choosing a case for your custom mechanical keyboard. The case is an essential part of the keyboard because it houses all the components. There are several materials to choose from, including plastic, wood, aluminum, and even steel. Each material offers its unique characteristics; for example, plastic and wood cases produce a softer typing sound, while metal cases offer a sturdier and more robust feel. Subsequently, you can pick the color or finishes that align with how you want your keyboard to look.
After picking your case, it’s time to select a PCB (Printed Circuit Board). The PCB is the backbone of your keyboard and connects all the keys to your computer. Some PCBs come pre-laid out for certain case sizes, while others are programmable allowing for better customization. Make sure the PCB you select is of high quality and supports your chosen layout.
Next, consider your stabilizers. Stabilizers are attached at the bottom of longer keys such as the space bar, shift, and enter keys to prevent them from wobbling when pressed. Mechanical keyboard enthusiasts typically recommend using genuine Cherry stabilizers or Durock stabilizers for their high-quality build, which reduces typing noise and gives keys a smoother feel.
Alongside stabilizers, the choice of switches is critical. The switch is the component that registers a keystroke when a key is pressed. You can choose from a variety of switch types, including linear, tactile, and clicky switches. Linear switches offer smooth keystrokes, tactile switches provide a small bump when pressed indicating a keypress, and clicky switches create an audible click sound when activated. Again, the ideal switch type depends on your personal preference, typing habits, and intended use.
Once you’ve selected your switches, it’s time to consider your keycaps. Keycaps are the parts of the keyboard that display the symbols and letters. Like cases, keycaps are available in various materials including ABS plastic and PBT plastic. PBT plastic tends to be more durable and less prone to shine over time, while ABS plastic offers more vibrant color options. Select the one that resonates with your aesthetic taste and durability requirements.
Now that you have all your components, let’s move on to assembly. Start by placing your stabilizers onto the PCB. Each stabilizer will go into a long hole on the PCB, typically where the space bar, shift, and enter keys reside. Once the stabilizers are in place, insert the switches into the PCB then into the plate (should your case have one).
After all the switches are mounted, it’s time to solder the switches to secure them onto the PCB. For beginners, a temperature-controlled soldering iron is highly recommended. After soldering, conduct a test to ensure that each switch is functioning as it should.
Once testing is done, now you can finally install the PCB into the case. Make sure to align the USB port on the PCB with the cutout on the case then secure the PCB with screws. The last step is placing your keycaps onto the switches.
Maintenance of your new keyboard involves occasionally removing the keycaps to clean dust and debris and lubing the switches and stabilizers to ensure they remain in optimal performance.
Building a custom mechanical keyboard may seem like an intimidating task at first. But with careful planning, selection of quality components, and meticulous assembly, you get a peripheral designed to your needs and satisfaction.
This article has taken you from understanding the key components in a keyboard, choosing these components based on your preferences and needs, to the assembly and maintenance. Investing time and effort to create your personally designed mechanical keyboard promises an unmatched typing experience and a sense of accomplishment.
