Joe Scotto's ScottoChoczard Is a Fully-Wireless 3D-Printable Evolution of the ScottoHazard Keyboard

Maker and custom keyboard enthusiast Joe Scotto has released another of his open hardware keyboard designs, the ScottoChoczard — a hand-wired split ortholinear layout designed as a successor to his earlier ScottoHazard.

"About three months ago I built the ScottoHazard which was my first 'real' split keyboard," Scotto explains of his latest creation. "I have enjoyed it so much that I wanted to see what I could do to improve the design and the result is the ScottoChoczard."

The ScottoChoczard is visibly an twist on the earlier ScottoHazard, though larger: the twin 4×5 40-keys layout has been expanded to twin 4×6 for a total of 48 keys, all identically-sized and laid out in a gridded ortholinear fashion with no rake in the columns. The switches are lightweight-actuation Kailh Choc Pink mechanical switches with Scotto's custom-designed 3D-printed ScottoCaps Scooped keycaps on top.

The biggest change over the ScottoHazard, though, is that the ScottoChoczard is fully wireless. Both halves of the keyboard are driven by a Nice! Keyboards nice!nano, a compact microcontroller board designed to be pin-compatible with the Arduino Pro Micro, with a 750mAh battery for power — "which," Scotto says, "will give it about two months [of use] on a single charge."

This is far from Scotto's first keyboard design: discounting the aforementioned ScottoHazard, he's built the ultra-thin ScottoWing, a one-handed input device inspired by the Frogpad, the unusual-layout ScottoKatana, and the ScottoDeck, and the ergonomic Bluetooth-connected Scotto63 — though his most recent, the Scotto69 "Nice Edition," stands out as being the only one to feature a custom PCB rather than having its components hand-wired inside the 3D-printed case.
