Building a custom mechanical keyboard can be a rewarding project that enhances your typing experience and reflects your personal style. With a budget of under $150, you can assemble a high-quality keyboard without breaking the bank. This guide will walk you through the essential steps and tips to create your own custom mechanical keyboard.

Planning Your Build

Before purchasing parts, consider your needs and preferences. Think about the size, layout, switch type, and keycap design. Decide whether you want a full-size, tenkeyless, or compact layout. Research different switch types such as tactile, linear, or clicky to find what suits your typing style.

Choosing Components

Keyboard Case

Look for a durable case that fits your chosen layout. Popular options include aluminum, plastic, or wood. Many budget-friendly cases are available online for under $50.

PCB (Printed Circuit Board)

The PCB is the heart of your keyboard. Choose a compatible, hot-swappable PCB if you want easy switch changes. Ensure it supports your layout and has features like RGB lighting if desired. Good options are often priced between $20 and $40.

Switches

Switches influence the feel and sound of your keyboard. Budget around $0.50 to $1 per switch. Consider buying a switch tester to find your preferred type before purchasing in bulk.

Keycaps

Choose keycaps that match your style and comfort. PBT keycaps are durable and feel good. Sets can be found for around $20 to $30, often in various colors and profiles.

Assembling Your Keyboard

Gather all components and tools, including a soldering iron if your PCB isn’t hot-swappable. Follow the instructions specific to your PCB to install switches and keycaps. Take your time to ensure all connections are secure and properly aligned.

Testing and Final Adjustments

Connect your keyboard to a computer and test each key using online keyboard testers. Make adjustments as needed, such as re-seating switches or cleaning components. Customize lighting or firmware settings if applicable.
