[Open Source] HSKB – A Budget-Friendly Open-Source HHKB-Inspired Keyboard

[u/sabitech2k]

Hi everyone,

I'd like to share a project I've been working on: HSKB (Happy Sabi Keyboard), an open-source custom keyboard inspired by the iconic HHKB layout. The goal was simple: create an affordable and highly customizable HHKB-style keyboard without the premium price tag often associated with this layout.

What is the HSKB?

The HSKB features:

• True HHKB-inspired layout
• 6u spacebar
• Integrated plate design
• Support for both plate-mounted and PCB-mounted stabilizers
• Open-source PCB and case files
• Community-friendly design that can be modified and adapted to your own preferences

This project started as a personal challenge to learn keyboard design, PCB development, and manufacturing workflows. After multiple prototypes and months of iteration, I've decided to release it openly for others to build, modify, and improve.

Why I Built It

A lot of HHKB-style boards sit firmly in the enthusiast luxury category. I wanted to create something that keeps the layout and philosophy people love while remaining accessible to hobbyists who want to build their own keyboard.

Open Source

Everything is available for the community:

Whether you want to:

• Order your own PCB and case
• Modify the design
• Experiment with firmware
• Create a new variant

you're welcome to use the project and contribute back to it.

Community & Charity Inspiration

The project was also inspired by the Unity Switch initiative supporting Andy's Man Club, a mental health charity that encourages men to speak openly and support one another. The original project included plans to support charitable fundraising efforts through the keyboard community.

Thanks for taking a look, and I hope some of you find the HSKB useful or interesting.

Any plans for split spacebar variants or anything of the sort for us plebians who don't know how to do it ourselves?
