alt Hacker NewsShameless plug but I'm a doctor who made an ergonomic split keyboard called the TAIKO-01 (https://taiko.taikohub.com).
It's split in two so you can position them at shoulder width. It's angled so your wrists are in more natural positioning (reduced pronation), and curved to prevent finger overstretching (finger joints have arc-shaped range of motion). It's injection molded and hot-swappable.
I've been working on this since 2022 and am getting close to launch. It's gotten very good feedback from beta testers.
Looks great! What do you use for mouse though? I wish more split keyboards had some integrated pointer control (touch / trackball / thinkpad-like-stick) so I didn't need to move my hand all the time.
