When ergonomic keyboards are discussed, the conversation often jumps quickly to fully split designs - two independent halves, adjustable distance, tenting, and maximum configurability. These boards make sense: true splits provide the highest degree of geometric freedom. But there is a quieter category in between: semi-split keyboards. They remain a single piece while introducing separation and angling that subtly influences hand positioning and movement patterns. They correct the largest geometric mismatches without adding complexity. ...

When someone asks me: “What’s a good first ergonomic keyboard?”, I usually start with two ideas: a split layout (for wrists and shoulders) an ortholinear grid (to clean up finger travel) That’s exactly why Let’s Split keeps showing up in beginner recommendations — including in my own list in Best Ergonomic Keyboard for Beginners. If you’re building or buying your first keyboard, Let’s Split is one of the boards I keep coming back to. Not because it’s the most exotic - but because it delivers the ergonomic fundamentals with a learning curve that doesn’t punish you, and does not make you throw it away after couple of minutes. But “recommended” and “right for you” are not the same thing. So in this post I’ll review Let’s Split in a practical way: what it does well, where it’s limited, what the build path looks like, and who should skip it. ...

Ferris Sweep Wireless — the title says it all. In this post I’ll share my experience building this tiny keyboard in a wireless version. First things first: I have to thank Mr. Robert — without him this build would not have happened. Mr. Robert, thank you! :) Ferris Sweep Wireless To turn a Ferris Sweep into a wireless keyboard, we need three changes compared to the wired build: Replace the Arduino Pro Micro with a controller that supports Bluetooth Integrate a battery to power the controller Install firmware that supports a Bluetooth workflow Let’s go through each point. ...

As I’ve been building more ergonomic keyboards, I kept getting the same question: “How exactly are your keyboards built?” This post is my answer - a Ferris Sweep build log. I’ll show the process step by step so you can understand what goes into the build and what to watch out for. This build log is based on a Ferris Sweep Compact build — my “take to the office” keyboard: tiny, split, low‑profile, and easy to throw into a backpack. ...

Ferris Sweep Reviewed by EKI (Ergonomic Keyboard Index) This is an extended follow-up to my earlier Ferris Sweep reviews: 30% Keyboard Club – Ferris Sweep Review 34 Keys as a Daily Driver for Developers Those posts focused on hands-on impressions and my developer layout. Since then, I introduced the Ergonomic Keyboard Index (EKI) — a 0–20 scoring framework that lets us compare keyboards at a glance. In this article I apply the EKI to the Ferris Sweep to produce a concise, comparable score. Consider it an “extended review” aligned with the new scoring rules. You can visit EKI to comparison of Ergonomic Keyboard Index all reviewed by me keyboards. ...
