Peter Lyons blogs about making a new split ergonomic keyboard, named the Squeezebox:
I designed and built a split ergonomic keyboard with some ideas I’ve been wanting to try for over a year. Here are the main features of the keyboard:
Split design, obvs
staggered linear columns
customizable tailor fit column offsets
tailor fit per-finger vertical offsets
thumb cluster with 6 keys
I think the main design element that sets this apart for other similar keebs is the shape of the middle and bottom rows. They are arranged in a steep 100-degree corner and the home position for the finger rests simultaneously with the point of the finger resting on the middle row and the pad of the finger resting on the bottom row. You can type the middle row while maintaining contact with the bottom row, and vice versa. So there’s 2 separate keys that can be typed without any reaching.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
