If you’re feeling fancy or want something unique, wooden cases are a beautiful, though often pricier, option.

Printed Circuit Board (PCB)

The PCB is the electronic heart of your keyboard. When you press a key, it’s the PCB that notices and sends the signal to your computer. It’s important to choose a PCB that’s compatible with the switches and case you want to use.


Underneath each keycap, there’s a little device that makes the magic happen — the switch. It’s responsible for the feel and sound of your keystrokes.

Linear switches offer a smooth press, tactile ones give a little bump to signal the key press, and clicky switches add an audible click to that bump. Your choice here will define your typing experience, so think about what feels best under your fingers!


These are the pieces you see and touch all the time. Keycaps can dramatically change the look of your keyboard. They come in countless colors and styles, from simple and professional to bright and fun. Materials like ABS or PBT plastic affect both the durability and the feel of the keycaps.


Larger keys like the space bar and enter key can wobble without stabilizers. These small parts are crucial for a smooth and stable keystroke. Make sure to get quality stabilizers to avoid annoying rattles!


Sitting snugly between the switches and the PCB, the plate adds rigidity to your keyboard. It can be made of materials like steel, aluminum, or even carbon fiber. The plate influences the overall typing feel and sound, so choose one that complements your style.

With all these parts selected, you’re on your way to building a keyboard that’s uniquely yours. Get ready to put it all together and create something that feels good to type on and expresses your personal style!

Putting Together the PCB

Embarking on the assembly of a printed circuit board (PCB) for a custom keyboard is a thrilling venture, reminiscent of constructing a model kit where each component has its designated place.

Preparing the Switches

Begin by readying the switches, the miniature mechanisms that capture your key presses and essentially serve as the heart of your keyboard.

Ensuring Readiness

Before commencing, ensure that your PCB and, if utilized, the metal or plastic plate are prepared. The plate, a flat piece providing stability to the switches, usually rests atop the PCB, aiding in aligning the switches accurately.

Delicate Alignment and Secure Placement

Gently align each switch with the corresponding holes on the plate and PCB. Press down firmly until a satisfying click indicates that the switch is securely in place.

Exercise caution to prevent bending any pins during this process, especially when dealing with delicate components such as membrane keyboard switches.

Flush Fit and Avoiding Wobbling

As switches are inserted, confirm they sit flush with the plate and PCB, snugly without any wobbling. Address any resistance by double-checking alignment; avoid forcing switches into place to prevent damage.

Thorough Inspection

Upon placing all switches, inspect your work. Ensure each switch is fully pressed down, with no bent pins underneath. If a pin is bent, delicately straighten it with tweezers and reseat the switch.

Completing this step marks a significant milestone in constructing your custom keyboard. The PCB is now poised for the subsequent phase—soldering the switches to establish a stable, enduring connection.

Revel in the accomplishment and anticipate the gratification of using a device crafted with your own hands.


Time to Solder!

Embarking on the soldering journey resembles engaging in a craft project where the goal is to permanently unite electronic parts.

Harnessing the Soldering Iron

The primary tool is the soldering iron, akin to a mini fire poker, reaching high temperatures. It’s employed to melt solder, a special metal wire, creating a metallic adhesive.

This adhesive connects switches (keyboard buttons) to the PCB (printed circuit board), essentially serving as the keyboard’s brain.

Crucial Preliminaries

Before delving into metal melting, understanding that soldering demands a steady hand and concentration is vital.

Beginners are encouraged to practice on discarded electronics to gain proficiency without fear of making mistakes. Old radios, toys, or computer parts serve as ideal practice materials.

Prioritizing Safety

Given the soldering iron’s capacity to reach temperatures as high as 800 degrees Fahrenheit, safety is paramount. Seeking guidance from an adult when learning to solder for the first time ensures a secure environment.

Collaborative learning enhances safety and provides valuable tips. Adequate ventilation is crucial to disperse fumes generated during solder melting. Keeping a window open or using a fan redirects air away.

Additionally, wearing safety glasses shields the eyes from potential metal fragments. With proper precautions and practice, mastering the art of soldering is within reach.


Stabilize Your Keys

Have you ever noticed that the larger keys on a keyboard, like the spacebar and enter key, sometimes feel a bit shaky when you press them?

This is where stabilizers come into play. These small but mighty parts are tucked under these big keys to keep them level and steady.

Installing stabilizers is a straightforward task, but it’s essential to do it correctly for the best typing experience. First, locate the stabilizers and gently place them into their designated spots on the keyboard. They usually clip or snap into place.

Once they’re in, give them a little wiggle to make sure they’re secure. It’s a bit like checking the wheels on a toy car; they should be firm but still able to move smoothly.

Next, align the larger keys with the stabilizers. Carefully press down until you hear a satisfying click, which means the key is attached correctly. It should feel snug, not loose or wobbly.

Finally, test out the keys by pressing them a few times. They should move straight down without any tilting or sticking. If everything feels right, you’ve successfully stabilized your keys, and your typing will be more comfortable and accurate.

Remember, taking the time to install your stabilizers properly will ensure your typing is stable and smooth, making your overall keyboard experience much better.


Test Your PCB

Before delving into the final stages of your keyboard project, it’s imperative to confirm the flawless operation of each component. The Printed Circuit Board (PCB) serves as the heart of your custom keyboard, and conducting a thorough test is an indispensable step.

Connectivity Check

Begin by connecting your PCB to a computer using a USB cable, providing it with the necessary power and connectivity to validate its operational status.

Key Testing

Gently press each key, observing the corresponding characters on your computer screen. Ensure not only responsiveness but also accurate mapping of characters or functions. If a key fails to register, explore potential solutions before getting concerned.

Inspect Soldering

Examine your soldering work, akin to gluing components together with metal. Look for loose connections or solder blobs causing short circuits. A well-executed solder joint should exhibit smoothness and shine. Beginners can seek guidance from experienced individuals or tutorials for improved soldering techniques.

Switch Seating

A non-responsive key might result from an improperly seated switch—the component that physically moves when a key is pressed. Confirm its snug fit into the PCB; any looseness may disrupt the electrical contact essential for transmitting the key’s signal to the computer. Gently push down on the switch to ensure full insertion. If issues persist, consider replacing the switch.

Patience is Key

Testing, though occasionally tedious, is pivotal for a well-functioning keyboard. Exercise patience, troubleshoot diligently, and pave the way for a successful build.

Assemble the Case

Great job on getting this far! Now that your printed circuit board (PCB) is decked out with all the switches, it’s time to nestle it into its new home—the case.

Carefully align the PCB with the case, making sure all the holes for screws line up properly. If everything looks good, it’s time to secure the PCB in place. You might need a screwdriver for this part.

Grab the screws that came with your case and start fastening the PCB. Turn the screws clockwise, but remember not to tighten them too much. Over-tightening could damage the PCB or the case.

Think of it like buttoning up a jacket—secure, but not squeezing tight. After all the screws are in, give your keyboard a little shake to make sure everything is snug and secure. No rattling means you’ve done it right!

Now, take a step back and admire your work. Your custom keyboard is really taking shape, and it’s almost ready for action.

The switches are in place, the PCB is secured, and it looks almost like the high-end keyboards you see in stores. You’ve built this with your own two hands, and that’s something to be proud of!

Next up, we’ll be adding keycaps, but let’s just enjoy this moment. The body of your keyboard is complete, and it’s a reflection of your hard work and attention to detail.

Add the Keycaps

The final touch to your custom-built typing device is putting on the keycaps. This is the fun part where your creativity shines through. You can choose from a rainbow of colors and a variety of designs to truly make it your own.

The process is simple: just align each keycap with its corresponding switch and press down firmly. You’ll know it’s properly in place when you hear a satisfying click. This sound means the keycap has snapped onto the switch and is secured.

Before you start, make sure your hands are clean to avoid transferring dirt or oil onto your new keycaps. If you’re using a keycap puller—a handy tool for this job—gently hook it under the edges of the keycap and pull upwards.

Without a puller, you can still use your fingers, but be careful not to use too much force which could damage the keycaps or switches.

If you’re wondering about the right order to place them, most keyboards follow a standard layout. However, you might have a custom layout in mind or even special keys that showcase your personality or interests.

Whatever your design, starting from one corner and working your way across the board is usually easiest. Also, don’t forget the spacebar—it’s often the largest key and may require a bit more pressure to attach.

And there you have it, your very own input masterpiece. Each keycap not only defines the look of your keyboard but also contributes to the feel and sound of your typing.

Whether you prefer a quiet or a clicky experience, your choice of keycaps can make all the difference. Enjoy the fruits of your labor and the unique touch your personalized keycaps bring to your daily typing adventures.
