Article note: Oh no, the Datahand clones are getting credible.
I really like the optical/magnetic switch/sensor rig every time I look at it... it's getting dangerously close to "looks like a fun project."
Also, the word "keeb" needs to not enter the lexicon.
What’s the coolest-looking way to ease the repetitive stress of typing without quitting altogether? Move nothing but your fingers, and move them as little as possible without any stretching or reaching. We’ve been fans of the weirdly wonderful DataHand keyboard since we first laid eyes on one, but [Ben Gruver] has actually been using these out-of-production keyboards for years as a daily driver. And what do we do when we love something scarce? Make our own, improved version like [Ben] has done, with the lalboard.
[Ben] has been using the lalboard for about two years now and has a laundry list of improvements for version two, a project we are proud to host over on IO. Many of the improvements are designed to make this massive undertaking a bit easier to print and put together. Version one uses copper tape traces, but [Ben] is working on a fab-able PCB that will use something other than a pair of Teensy 2.0s, and perhaps QMK firmware.
Something that won’t be changing is the fantastic optical key switch design that uses an IR LED and phototransistor to capture key presses, and tiny square magnets to return the key to the home position and deliver what we’re quite sure is a satisfying clack.
The absolute coolest part of this keyboard is that it’s so adjustable. Every key cluster can be adjusted in 6 directions, which includes the ability to dial in different heights for each finger if that’s what works best. Once that’s all figured out, then it’s time to print some perfect permanent standoffs. Want to make one of these sci-fi clackers for yourself? [Ben] has the BOM, some printing instructions and tips, and a guide to making the copper tape PCBs over on GitHub. Check it out in action after the break as [Ben] rewrites Kafka’s Metamorphosis at 120 WPM.
