The Redox 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 mechanical keyboard community is constantly coming up with great new designs and different DIY keyboards and we’ve featured many of them on the site. After you’ve checked out the pictures and schematics [Mattia] has created, take a look at this 3D printed mechanical keyboard, and details of a keyboard design and build were presented at the Hackaday Superconference in 2017.

This Keyboard And Mouse Also Gives You A Workout

The Ergonomic Handheld Mouse / Keyboard Alternative from [Shervin Emami] is an all-in-one solution for your keyboarding and cursor moving needs.

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.

Ergonomic Keyboard Designed from the Ground Up

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.

Raspberry Pi Powers the Desk of the Future

Recent science fiction movies always show people sitting at stylish semi-transparent desks that have all kinds of strange and wonderful gadgets in them. Our desks look like something your grandfather might have sat at. [Frederick Vandenbosch] must have seen those same movies so as part of contest he decided to build the desk of the future.

The desk is as much a furniture project as an electronics project, but it does have a Raspberry Pi, a scavenged laptop LCD, embedded touch sensors and LEDs, a wireless charger, and a built-in sound system. In addition, it uses a Gertbot and some stepper motors that it uses to raise and lower the screen in and out of the desk (watch the video below to see how that looks).

[Fredrick] used Python to get the major functions of the desk programmed. We couldn’t help but think of all the things you could do with an easily programmable desk surface: show stock quotes (or sports scores), notify about e-mail, or other things. Although it doesn’t look like it would be simple for a simple user to add those things, if you were a handy programmer, they look like they’d be in reach.

We’ve seen some desks before, but nothing quite like this. We couldn’t help but wonder if you could add some Minority Report-style goodness to [Frederick’s] already impressive desk.

Apple Forces Non-Mac User To Make Ergonomic Mac Keyboard

Mac Ergonomic Keyboard

If you’ve ever typed for a significant amount of time you know that it can become painful. Long term exposure can cause wrist and arm injuries. There are some things that can help alleviate the risk of injury like taking frequent breaks, good posture and using an ergonomic keyboard. [Ian] likes the feel of Mac keyboard keys but doesn’t like the traditional straight layout. Unfortunately, Apple doesn’t make an ergonomic keyboard so [Ian] stepped up to the plate and made one for himself.

Mac Ergonomic Keyboard

Just starting this project was an extreme pain. Apple glues their Mac keyboards together. A heat gun was used to melt the glue to 400°F as kitchen utensils were stuck in between the halves of the case, keeping the glue from re-sealing the case together. Once the case was apart the unnecessary keys were removed. [Ian] is actually modifying two keyboards into one because he wants the middle keys to show up on both sides of the keyboard. With the necessary keys identified, the metal support frame was removed from the unneeded sides of the keyboard.

Cheap ergonomic mouse

If your had keeps cramping while using the computer mouse why not grab a hunk of wood and a couple of buttons to make your own ergonomic input device?

C# GUI for Arduino testing

Here’s a Windows GUI for controlling Arduino. [Rohit] put it together using C#. It should make development very simple as you have control of almost everything before you need to worry about writing your own server-side software.

Networked strip lighting replaces the office overheads

[Jeremy] got tired of replacing the halogen bulbs in his office. He upgraded to ten meters of RGB LED strips. We can’t think they do as well at lighting up the room. But he did add network control so they can flash or change colors depending on what type of alert they’re signalling.

Woven QR codes

Now that [Andrew Kieran] proved you can weave a working QR code into textiles do you think we’ll see garments that have a QR code leading to care instructions? We could never figure out what all those strange icons stood for.

World’s largest QR code in a corn maze

The world’s largest QR code was cut out of this field of corn. It’s at the Kraay Family Farm in Alberta, Canada. Gizomodo called it “Stupidly Pointless”. But we figure if it got them a world record and put their website on the front page of Giz and Hackaday they’re doing okay. Plus, we whipped out our Android and it read the QR code quite easily.

BAMF2011: Keyboards built from scratch

As the most direct interface between computer and programmer, keyboards can be a deeply personal, sometimes almost religious thing. Some find solace in their vintage IBM Model M, or luxurious leather keyboard, but maker [Carol Chen] took things into her own hands, quite literally. [Carol]’s Maker Faire exhibit has a half dozen specimens of interesting commercial tactile and ergonomic options…but [Chen]’s personal keyboard, where she commits to her work as a full-time coder, has been made to her own exacting specifications.
