From the smallest 60% keyboards for those with no desk space to keyboards with number pads for those doing data entry all day, there’s a keyboard size and shape for just about everyone. The only problem, even with the largest keyboards, is that they’re still fairly limited in what they can do. If you find yourself wishing for even more functionality, you might want to build something like this custom macro keyboard with built-in LED backlighting.

Rather than go with a standard mechanical keyboard switch like a Cherry MX, this build is based around TS26-2 pushbuttons with built-in LED lighting. [atkaper] only really needed one button for managing the mute button on MS Teams, but still built a total of eight switches into this keyboard which can all be individually programmed with different functions. The controller is an Arduino Leonardo and the enclosure was 3D printed.

Paired with the classic IBM Model M keyboard, this new macro keyboard adds plenty of functionality while also having control over LED backlighting. Macro keyboards are incredibly useful, especially with their ability to easily change function with control over the software that runs on them. The key to most builds is the 32U4 chip found in some Atmel microcontrollers which allows it to easily pass keyboard (and mouse) functionality to any computer its plugged in to.

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.

[MechEngineerMike] wrote in to share the enthusiasm over SimpleSumo, a series of open source, customizable robots he designed for mini-sumo battling and much more. For the unfamiliar, mini-sumo is a sport where two robots try to push each other out of a ring. [Mike]’s bots are simplified versions designed for education.

[Mike] was inspired by a video of some kids building mini-sumo bots who were doing anything and everything to personalize them. He vowed to make his own affordable, easy-to-build bots with education firmly in mind. His other major requirement? They had to be as easily customizable as that one potato-based toy that eventually came with a bucket of parts. As of this writing, there are 34 interchangeable accessories.

[Mike]’s first idea was to build the bots out of custom 3D-printed building blocks. He soon found it was too much work to print consistent blocks and switched to a modular cube-like design instead. SimpleSumo bots can do much more than just fight each other. [Mike] has written programs to make them flee from objects, follow lines, find objects and push them out of the ring, and beep with increasing frequency when an object is detected.

The bots are completely open source, but [Mike] sells kits for people who can’t print the parts themselves. He’s made a wealth of information available on his website including links to outside resources about mini-sumo, Arduino, programming, and 3D design. How about a complete series of assembly videos? First one is after the break.  Don’t know how to build a battle ring? He’s got that covered, too.

For a sumo bot that’s more brains than brawn, check out Zumo Red, the smart sumo.

Writing code for an Arduino-friendly board is relatively easy; creating the board is the hard part, unless you live and breathe electrical engineering. If HackEDA has its way, however, the design process could be almost as easy as window shopping. Its new Kickstarter-backed project lets tinkerers choose from a list of parts and get a made-to-order board without knowing a lick about PCB assembly -- algorithms sort out the finer details. While the initial effort includes just 36 combos based around an Atmega328 processor, contributors who want tangible hardware can pay anything from $30 for a bare board through to $10,000 for the first stages of mass production. The truly committed will have to wait until December for the finished goods, but those willing to try HackEDA can use its existing web tool for free.

If you're going to revisit a certain underwater dystopia, you might as well have a ball. At least that's the approach being taken by Sweden-based DIYer rasmadrak, who has decided to build a Bioshock-themed custom pinball machine just for kicks. The project is filled with lots of neat little touches from Rapture, including Little Sister vents and a few Big Daddy homages. The builder also does a pretty good job of drilling into the details and providing insight on the creation process -- like the challenge in using two different systems such as Arduino and chipKIT together, for example -- via detailed posts in the Poor Man's Pinball! blog. The project proved to be a pleasant shock to the system for fellow pinball aficionado Ben Heck, who gave the project a sprinkling of Heckendorn love via Twitter. Pinball geeks can also follow the saga, so to speak, by checking out the source link below.

If you prefer reading your RSS feeds without the backlight, there's hardware for that, and if you'd prefer not reading your Twitter feeds at all, there's now hardware for that as well. Mix an Arduino Ethernet board, an Emic 2 Text-To-Speech Module and the knowhow to put them together, and you've got SocialChatter -- a neat little build that'll read your feeds aloud. The coding's already been done for you, and it's based on Adafruit's own Internet of Things printer sketch with a little bit of tinkering so nothing's lost in translation. If your eyes need a Twitter break and you've got the skills and kit to make it happen, head over to the source link for a how-to guide. Don't fill the requirements? Then jump past the break to hear SocialChatter's soothing voice without all the effort.

In this instructable, Dustin Andrews shows how to make a custom Arduino board, equipped with a lcd, a buzzer and a solid enclosure. Dustin’s goal has been to design a rugged Arduino version, that can be employed “as is” in many practical project, in place of a less solid breadboard-based solution.
