Keebin’ With Kristina: The One With The Breadboard Macropad

February 8, 2023 by 6 Comments

For their first custom, hand-wired keyboard, [terryorchard] aka [70rch] didn’t want to mess with making a total split, and we don’t really blame them. However, as you can see, they ended up with a monoblock split, which aside from being our own personal preference, looks fantastic, and also happened to be what fit on the print bed.

What you’re looking at is a 40% remix of the Alice layout with a columnar stagger. It’s also a bit 6×3 Corne-inspired on the ergonomic front. Brain-wise, it’s got an exposed Elite Pi driving a matrix of Kailh Choc pinks and an EC11 encoder. The encoder scrolls by default, and then becomes a volume knob on the numbers and symbols layer. One super cool thing about this keyboard is the secret third layer, which is unlocked by pressing the rotary encoder. This leads to some home row mods and disables the outside columns, culminating in a test 3×5 with two layers.

A Fun Low-Cost Start For Your Macropad Hobby

December 30, 2022 by 7 Comments

If you were ever looking for a small relaxing evening project that you could then use day-to-day, you gotta consider the Pico Hat Pad kit by [Natalie the Nerd]. It fits squarely within the Pi Pico form-factor, giving you two buttons, one rotary encoder and two individually addressable LEDs to play with. Initially, this macropad was intended as an under-$20 device that’s also a soldering practice kit, and [Natalie] has knocked it out of the park.

You build this macropad out of a stack of three PCBs — the middle one connecting the Pi Pico heart to the buttons, encoders and LEDs, and the remaining ones adding structural support and protection. All the PCBs fit together into a neat tab-connected panel — ready to be thrown into your favorite PCB service’s shopping cart. Under the hood, this macropad uses KMK, a CircuitPython-based keyboard firmware, with the configuration open-source. In fact everything is open-source, just the way we like it.

If you find yourself with an unexpected affinity for macropads after assembling this one, don’t panic. It’s quite a common side-effect. Fortunately, there are cures, and it’s no longer inevitable that you’ll go bananas about it. That said, if you’re fighting the urges to go bigger, you can try a different hand-wireable Pico-based macropad with three more keys. Come to find that one not enough? Here’s a 2×4 3D printable one.

Now, if you eventually find yourself reading every single Keebin’ With Kristina episode as soon as it comes out, you might be too far gone, and we’ll soon find you spending hundreds of dollars building tiny OLED screens into individual keys — in which case, make sure you document it and share it with us!

Keebin’ With Kristina: The One With The Hexagonal Keyboard

September 15, 2022 by 16 Comments

Well, I didn’t mean to take the whole summer off from Keebin’, it just kind of happened that way. You’d think it would have been #13 that tripped me up, but we ain’t even there yet — this is only the twelfth edition. I kept thinking I should write one and it just wasn’t happening, until I got a tip from [s.ol bekic] about their stunning hexagonal keycaps and the journey toward making an open-source 12-key macropad featuring same.

But let’s back up a bit. Originally, [s.ol] designed a totally sick hybrid MIDI-and-typing keyboard from scratch, which you can see in this short video. It glows, it splits in half, and it snaps back together again quite satisfyingly. And you probably noticed the hexagonal keycaps that look like they might be printed or milled, or perhaps even printed and then milled.

In actuality, [s.ol] threw all the processes at this keycap project — milling, molding and casting, and 3D printing. None of them worked well enough to get much past the prototype stage, but in the end, [s.ol] joined forces with fkcaps.com to create and offer an injection-molded version that I’d really, really like to rock my fingertips around in. Good thing I can pick some up for cheap.

Of course, the real process was all the learning [s.ol] did along the way — both in the early days of making the hybrid keyboard, and after teaming up with fkcaps to make the keycaps and the accompanying macropad into real products. And that was after all the design work it took to get this newfangled honeycomb configuration right.

In case you’re wondering, these are meant for only Kailh chocs, but no matter the switch, the spacing is really important because of all the possible points of friction introduced by the design. Be sure to check out the keycap docs page, macropad docs page, and this gallery of keycaps and macropads.

Pretty Pico Macropad Eases Transition Back To Office

September 3, 2022 by 33 Comments

[Thomas “Mel” Maillioux] is no stranger to the custom mechanical keyboard game — and faced with having to return to the office, they decided to whip up a sweet little macropad to both commemorate the occasion and make work a bit easier.

This cotton candy-colored block of beauty was designed to pay homage to [Mel]’s favorite joystick, the TRS-80 self-centering number with the single red, square button, and it looks fantastic. They started this journey by studying the key legends on their laptop to determine which macros might serve them best, based on which legends were the most worn.

Fortunately, all the macros they wanted to use — lock the workstation, save the current, active file, minimize/restore all windows, snap windows to the right or left, and volume control — are all macro’d already within Windows, so that made things rather easy.

Hardware-wise, it doesn’t get much easier than a Raspberry Pi Pico, some mechanical switches, an old USB cable, and donor CAT5 pairs so it looks pretty inside and out. Plus, the handy rotary encoder volume knob will mute and un-mute when pressed. We think the snap-fit enclosure looks great, and it needs no supports to boot. If you want to make your own, be sure to check out the repo.

Okay, we lied: macro pad making does get easier, provided you have access to a 3D-printer.

The First-Ever Kansas City Keyboard Meetup Is This Weekend

August 23, 2022 by 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.

Deepdeck: Going Beyond The Macro Pad

August 20, 2022 by 4 Comments

We’re used to the idea of a macropad, a small extension keyboard for your computer whose keys can be programmed to the functions of your choice. They can be made in many ways, but they all follow a similar functionality. Deepdeck from [Nick Velasquez] is another matter, an attempt to make a macropad with functionality that goes way beyond simply pressing keys.

At its heart is an ESP32 module, and it makes full use of both Bluetooth and wireless networking capabilities. It can use Bluetooth when connecting to the host computer, and the wireless connection hosts both the configuration interface via a web server and an Internet connection from which it derives those special powers.  This is a macropad with programmable keys just like all the others, but it also has the ability to connect to online APIs programmed by the user. This allows it to automate complex queries involving other sources into a keypress, which gives it many more possibilities.

A tool such as this one is one of those things which requires a bit of thought as to exactly how it might be used. A normal API connected device might display the weather on a screen for instance, but how often does one need to type the weather forecast? However we can see that this extra online dimension will find as yet unseen applications, and we look forward to the idea being taken up with other macropads.

A Customizable Macropad To Make Anyone’s Tail Wag

July 28, 2022 by 4 Comments

[Gili Yankovitch] has always wanted some kind of macro keypad for all those boss-slaying combos he keeps up the sleeve of his wizard robe while playing WoW. Seventeen years later, he finally threw down the gauntlet and built one. But really, this is an understatement, because Paws is kind of the customizable macropad to end all customizable macropads.

This thing is completely bespoke, and yet cookie cutter at the same time — but we mean that in the best possible way. Paws can be made in any shape or form, and quite easily. How is this even possible, you ask? Well, every single key has its own microcontroller.

Yep, each key has an ATtiny85 and a cute little ribbon cable, and these form a token ring network that talks to an Arduino, which provides the keyboard interface to the computer. To make things even easier, [Gili] built a simple programming UI that automatically recognizes the configuration and number of keys, and lets the user choose the most important bit of all — the color of the LED.

[Gili] wanted to combine all the skills he’s learned since the worst timeline started in early 2020 — embedded software, CAD, electronics, and PCB design. We’d like to add networking to that list, especially since he figured out a nice workaround for the slowness of I²C and the limitations of communication between the ‘tiny85s and the Arduino. Though [Gili] may have started out with a tall order, he definitely filled it. Want to get your paws on the design files? Just claw your way over to GitHub.
