The First-Ever Kansas City Keyboard Meetup Is This Weekend

August 23, 2022 by Kristina Panos 18 Comments

Sometimes, if you wait long enough for something you want, it will come to you. Whether it’s the law of attraction or just plain laziness, it has finally happened — there’s a keyboard meetup happening within a 500-mile radius of me. As far as I know, it’s the first one ever in Kansas City. I’m going, I’m bringing weird keyboards, and I might even have some Hackaday stickers to sprinkle around.

Although the event was originally planned to take place in the side room of a coffeehouse in the historic northeast, it was quickly moved to a much larger, co-working space downtown to accommodate all the maniacs like yours truly who want to bring a whole bunch of keebs. I’m even bringing some tables, y’all.

This’ll be more than just a show and tell, because what kind of object-focused nerd gathering would be complete without a swap meet element? You’re probably going to find that all kinds of keyboards and keyboard accessories are for sale, but you also might get lucky and win a cute bag of switches from Kinetic Labs, or a 3×4 macro pad from Boardsource (who will also have stickers on hand).

Come for the cool keyboards, and stay for the conversations you’ll strike up with the awesome folks who brought them. Who knows, maybe we’ll all infiltrate the slammin’ ice cream shop down the street.

Questions? Comments? Just want to share your excitement? Come join the Discord! If you’re planning to show up on Saturday, please take a second to fill out the head count document. If you do, it’ll probably net you a deli sandwich when you get there.

If you can’t make it, that’s okay — stay tuned for coverage of the event, and start planning for the next one, because hopefully, there will be many more to come.

Getting To The TrackPoint Quicker

August 15, 2022 by Matthew Carlson 10 Comments

Love it or hate it, TrackPoint can be a powerful tool. Love it or hate it, the idea of moving the mouse without removing your hands from the keys has an appeal. [Alon Swartz] incorporated one into his custom wired split mechanical keyboard and wrote a helpful guide on how to do it yourself.

The first step was to determine the pinout of the Trackpoint, which he provides a handy repository of various devices with annotations and pictures. The next step is swapping the little rubber nub at the top for something a bit longer. As the PCB sits below the keys, a labret cheek piercing happens to be a perfect candidate. Strong, thin, easily obtainable in different lengths, and threaded on one end. With jewelry in hand, [Alon] created a reset circuit with just a few resistors and a capacitor so the teensy can trigger a reset of the Trackpoint. The keyboard’s TMK firmware also needed a few tweaks to support reading the Trackpoint.

It’s a great guide, and we love the use of the jewelry as a piece of the keyboard. A knitting needle was used in a previous attempt to add a Trackpoint to a mechanical keyboard, and we’re excited to see what other household items end up in keyboards.

From Product To Burnout To Open-Source: The Ergo S-1 Keyboard Story

August 10, 2022 by Arya Voronova 21 Comments

[Andrew] from [Wizard Keyboards] emailed us and asked if we were interested in his story of developing an ergonomic keyboard as a product. Many of us can relate to trying to bring one of our ideas to market. [Andrew], being a mechanical keyboard geek, knew a niche with no product to satisfy it, and had a vision he wanted to implement. He started meticulously going through steps for bringing his keyboard idea into life as a manufacturable product, and gave himself six months to get it done.

After evaluating competing products and setting a price point, he designed the case, the keyboard’s mainboard, and even flexible circuit boards for wiring the keys up. The mechanical design alone had him go through many iterations and decisions, and he walks us through the different paths he’s faced. Whether it’s these insights, a story of a module with fraudulent FCC certification, or an approach to electronics design that led to him passing EMC tests with flying colors, there’s plenty to learn from [Andrew]’s journey.

Sadly, at some point, the project quickly outgrew the intended goal and became a drain. For instance, tuning the 3D printing processes alone took three months instead of one as planned. As the design was done, he got stuck on marketing material production – a field that turned out to be unexpectedly hostile to a hacker like him. After a year of work and five thousand hours of work spent on the project, he took a break, and afterwards, as he was trying to come back, [Andrew] realized that he has burned out. He took a few month long hiatus, and having recovered a bit, revisited the project. Still not thrilled about the product route, he decided that open-sourcing the keyboard would be the best outcome – doing justice to the time and effort spent working on it.

This is where the story ends – for now. [Andrew] has open-sourced everything one would need to create such a keyboard by yourself, designed assembly instructions, and even sells kit parts for those who’d like to take a shortcut. This wasn’t what he aimed for, but it’s a honorable ending – most commercial projects never get open-sourced even if they utterly fail to launch. Thanks to [Andrew], we got an insightful journey, a postmortem, and an open-source ergonomic keyboard project. Product stories grace our pages every now and then – here’s a similarly swerving story about a MIDI controller.

Nokia 5110 Gets Android Stowaway And A Keyboard

July 21, 2022 by Bryan Cockfield 11 Comments

Even though Nokia is largely an afterthought in the phone market now, there was a time when their products represented the state-of-the-art in mobile devices. Some of the their handsets even featured slide-out keyboards and the ability to sent emails; largely unheard of for a device from the late 90s. [befinitiv] was a kid back then and couldn’t afford one of these revolutionary devices, so he built his own modern version that still looks and feels like the original.

To do this he borrowed the case and structure of a Nokia 5110 phone, but modified it to hold a small Android device in the old battery compartment along with a tiny Bluetooth keyboard (which was also built from scratch by [befinitiv]) that connects to the Android phone to mimic the old slide-out style. This isn’t just a case mod, though. He also reverse-engineered the original PCB of the phone and included a Bluetooth module there as well, which allows the phone’s screen and keypad to work mostly as originally intended.

This project goes pretty far to scratch the 90s phone nostalgia itch while still being largely usable as a real phone in the modern world. Assuming you aren’t too hung up on the literal phone aspect, the Notkia project is also an impressive effort to bring new life to these old handsets.

Overwhelmed By Odd Inputs: The Contest Winners And More

July 13, 2022 by Elliot Williams 1 Comment

The Odd Inputs and Peculiar Peripherals Contest wrapped up last week, and our judges have been hard at work sifting through their favorite projects. And this was no easy task – we had 75 entries and so many of them were cool in their own right that all we can say is go check them all out. Really.

But we had to pick winners, not the least because Digi-Key put up three $150 gift certificates. So without further ado, here are the top three projects and as many honorable mentions as you have fingers and toes – if you don’t count your thumbs.

The Prize Winners

Keybon should be a mainstream commercial product. It’s a macro keypad with an OLED screen per key. It talks to an application on your desktop that detects the program that you currently have focused, and adapts the keypress action and the OLED labels to match. It’s a super-slick 3D-printed design to boot. It’s the dream of the Optimus Maximus, but made both DIY and significantly more reasonable as a macro pad. It’s the coolest thing to have on your desk, and it’s a big winner!

On the ridiculous side of keyboards, meet the Cree-board. [Matt] says he got the idea of using beefy COB LEDs as keycaps from the bad pun in the name, but we love the effect when you press down on the otherwise blinding light – they’re so bright that they use your entire meaty finger as a diffuser. Plus, it really does look like a keypad of sunny-side up eggs. It’s wacky, unique, and what’s not to love about that in a macropad?

Finally, [Josh EJ] turned an exercise bike into a wireless gamepad, obliterating the choice between getting fit and getting high scores by enabling both at the same time. An ESP32-turned-Bluetooth-gamepad is the brains, and he documents in detail how he hooked up a homebrew cadence sensor, used the heart-rate pads as buttons, and even added some extra controls on top. Watching clips of him pedaling his heart out in order to push the virtual pedal to the metal in GRID Autosport, we only wish he were screaming “vroooom”.

A Handy Tester For A Mountain Of PS/2 Keybords

July 12, 2022 by Dan Maloney 16 Comments

The hacking life is not without its challenges, and chief among these is the tendency to always be in acquisition mode. When we come across a great deal on bulk equipment, or see a chance to rescue some obscure gear from the e-waste stream, we generally pounce on it, regardless of the advisability.

We imagine this is why [Nathan] ended up with a hoard of PS/2 keyboards. Seriously, there are like thousands of the things. And rather than lug a computer to them for testing, [Nathan] put together this handy Arduino-based portable tester to see which keyboards still have some life left in them. The video below goes into detail on the build, but the basics are pretty simple — an Arduino, a 16×2 LCD display, and a few bits and bobs to run it off a LiPo pack and charge it up. Plus, of course, a PS/2 jack to plug in a keyboard and power it up. Interestingly, the 16×2 display is an old Parallax unit, from the days when RadioShack still existed and sold their stuff. That required a little effort to get it working with the Arduino, but in the end it works like a charm — plug in a keyboard and whatever you type shows up on the screen.

Of course, it’s hard to look at something like this, and that mountain of keyboards in the background, and not scheme up ways to really automate the whole test process. Perhaps an old 3D printer with a stylus mounted where the hot end would go could press each key in turn while the tester output is recorded — something like this Wordle-bot, but on a keyboard scale. That kind of goes against [Nathan]’s portability goal, but it’s still fun to think about.

Mechanical Keyboards Are Over, This Device Has Won

June 24, 2022 by Jenny List 37 Comments

The desk of any self-respecting technology enthusiast in the 2020s is not complete without a special keyboard of some sort, be it a vintage IBM Model M, an esoteric layout or form factor, or just a standard keyboard made with clacky mechanical switches. But perhaps we’ve found the one esoteric keyboard to rule them all, in the form of [HIGEDARUMA]’s 8-bit keyboard. You can all go home now, the competition has been well and truly won by this input device with the simplest of premises; enter text by setting the ASCII value as binary on a row of toggle switches. No keyboard is more retro than the one you’d find on the earliest microcomputers!

Jokes aside, perhaps this keyboard may be just a little bit esoteric for many readers, but it’s nevertheless a well-executed project. Aside from the row of binary inputs there is a keypress button which sends whatever the value is to the computer, and a stock button that allows for multiple inputs to be stored and sent as one. If you pause for a moment and think how often you use Ctrl-C and Ctrl-V for example, this is an essential function. There’s more information on a Japanese website (Google Translate link), which reveals that under the hood it’s a Bluetooth device running on an ESP32.

We can imagine that with a bit of use it would be possible to memorize ASCII as binary pretty quickly, in fact we wouldn’t be at all surprised to find readers already possessing that skill. But somehow we can’t imagine it ever being a particularly fast text input device. Take a look for yourselves, it’s in the video below the break.
