Each finger hovers over a C-shaped group of three switches — one actuates by moving the finger forward, another by moving backward, and the third by pushing down like a regular button. The thumb gets a 4-way joystick. All of these inputs are wired up to an Arduino Pro Micro, which has sort of become the standard for DIY macro pads and keyboards. We think this looks fantastic, and really raises the bar for DIY macro pads.
Tired of a boring, single piece keyboard? Thinking about a change but don’t know what all your options are? Well prospective-keyboard-shopper, today is your lucky day. We at the Hackaday are here to facilitate the habit with two excellent resources for the eager keyboard shopper; [pvinis]’s awesome-split-keyboards and [jhelvy]’s splitkbcompare.
As indicated by its title, awesome-split-keyboards is an awesome list of split keyboards 50 examples strong. Every split we’ve come across seems to be represented here, many with at least an image or two along with links to more information about how to build or buy the model in question. If that’s not enough, the bottom of the page has a wealth of background information about building or buying your own.
But before making such an important decision it’s important to make sure the keyboard in question will be a good fit in the hands. This is where splitkbcompare comes in, providing a visualization of many popular split layouts. If we hadn’t just found awesome-split-keyboards this filterable list and wide selection would have been the highlight here. But what does stand out is the ability to generate 1:1 scale printouts of the layouts in question, even stacking them for comparison, allowing a prospective buyer get a hands on feel for what they’re considering.
Whether you’re a programmer, gamer, writer, or data entry specialist, the keyboard is an extension of your nervous system. It’s not so much a tool as it is a medium for flow — for being in the zone. So I think it’s only natural that you should care deeply about your keyboard — how it looks, how it sounds, and above all, how it feels to finger-punch those helmeted little switches all the live-long day. That’s my excuse, anyway.
It might surprise you that mechanical keyboard switches can be modified in a number of ways. Depending on what you want from your keyboarding experience, you can make switches feel lighter or less scratchy, quiet them down, or tighten up any wobble in the housing. Why would you want to do this? Because customization is fun. Because electromechanical things are awesome, and because it’s fun to take switches apart and put them back together again. Because it’s literally hacking and this is Hackaday.
I got into switch modding because I wanted to put Cherry clears in my dactyl, but worried that they would take too much force to actuate and wear my fingers out. So I bought some really light (39g) springs and was really looking forward to swapping them into the clears, but they just don’t work. Like, physically. Slider goes down, slider gets stuck. It will come back up, but only if I hit it again and smear my finger to the side a bit at the same time. Those springs must be too weak to return clear sliders.
I took this as a sign that I should suck it up and use browns instead. After all, no one else has to know what my sliders look like. While I was opening switches, I tried out one of these super-light springs in a brown, thinking maybe they wouldn’t have to go to waste. Not only did the lighter spring work in the brown, it felt pretty nice. It’s hard to imagine how a whole keeb would feel based on a single switch, but if you can gather a handful and snap them into a plate to riffle your fingers over them, well, it’s probably close enough to a full keyboard to get a good feel for whatever mod you’re doing.
Okay, let’s just get this out of the way up front, shall we? This ergonomic mechanical keyboard was a free sample offered to me by X-Bows. They contacted me after I expressed interest in trying one in the comments of my post about the Kinesis Advantage. I had my doubts about this keyboard as far as my own personal ergonomic needs go, which are admittedly on the extreme side. TL;DR: I won’t be abandoning my curvy girls anytime soon. But I will say that I’m definitely impressed by the X-Bows.
X-Bows was founded by a doctor who saw a lot of RSI issues in programmers and writers and decided to take matters into his own hands. The keyboard was born on Kickstarter in 2017 and now comes in three models. They sent me the mid-range model called The Knight, which retails for $249, but seems to be on permanent sale for $199. The top-of-the-line Knight Plus has a magnetic, detachable 10-key that can attach to either side. Continue reading “Inputs Of Interest: X-Bows Ergo-Mechanical Keyboard”→
Alternative keyboard layouts like Colemak and Dvorak are nothing new; they allow easier access to more often used keys to reduce the strain placed on the hands during typing. Building on the popularity of the ergonomic Ergodox keyboard, [Mattia Dal Ben] has developed the Redox keyboard, the Reduced Ergodox, to make an even smaller, more ergonomic keyboard.
Like the Ergodox, the Redox uses a columnar layout, where the keys are laid out in columns, each column offset based on the corresponding finger. Where the Redox breaks away from the design of the Ergodox is the thumb keys. [Mattia] started having pain in his pinkies, so he wanted the thumb layouts to take away some of the extra work from the pinkies. The thumb cluster is smaller than its ancestor and includes an additional rotated thumb key.
The Redox has some great improvements over the Ergodox in order to help with the types of strain injuries most associated with typing, hopefully leading to a much nicer interaction with the peripheral that gets the most use.
The core of this build is a ‘grip-strengthening’ device that’s sold to guitarists. While the actual benefit of these devices for guitarists is questionable — there are a few anecdotes any music teacher will tell you about classical pianists ruining their hands with similar devices — the device itself can be converted into a fantastic chording keyboard. All you really need for a full-functioned keyboard is a few buttons in a rugged shell, and this ‘grip strengthener’ has that going in spades.
Underneath the plungers for each button [Shervin] installed a magnet and a magnetic sensor, meaning these buttons are analog, and shouldn’t wear out ever. With just a little bit of code on a Tiny BLE board these analog sensors can become a keyboard, a quadcopter controller, an interface for your VR setup, or anything else that can be controlled with a bunch of buttons.
Not to outdo himself, [Shervin] also managed to add some cursor control functionality to this build. This is done via the IMU onboard the Tiny BLE board, and by all accounts it works great. You can check out a video of this build pretending it’s both a keyboard and a mouse below.
In 2011, [Fabio] had been working behind a keyboard for about a decade when he started noticing wrist pain. This is a common long-term injury for people at desk jobs, but rather than buy an ergonomic keyboard he decided that none of the commercial offerings had all of the features he needed. Instead, he set out on a five-year journey to build the perfect ergonomic keyboard.
Part of the problem with other solutions was that no keyboards could be left in Dvorak (a keyboard layout [Fabio] finds improves his typing speed) after rebooting the computer, and Arduino-based solutions would not make themselves available to the computer’s BIOS. Luckily he found the LUFA keyboard library, and then was able to salvage a PCB from another keyboard. From there, he programmed everything on a Teensy microcontroller, added an OLED screen, and soldered it all together (including a set of Cherry MX switches).
Of course, the build wasn’t truly complete until recently, when a custom two-part case was 3D printed. The build quality and attention to detail in this project is impressive, and if you want to roll out your own [Fabio] has made all of the CAD files and software available. Should you wish to incorporate some of his designs into other types of specialized keyboards, there are some ideas floating around that will surely improve your typing or workflow.
