Keebin’ With Kristina: The One Where Shift (Really) Happens

February 23, 2023 by 5 Comments

Hooray, the system works! [Sasha K.] wrote to let me know about their Thumbs Up! keyboard, which is the culmination of a long journey down the DIY rabbit hole to end game. (Seriously, it’s kind of a wild ride, and there’s a ton of pictures).

Thumbs Up! comes in both monoblock and full split versions, but both are designed for Kailh chocs. Fans of the Kinesis Advantage will dig the key wells and possibly the thumb cluster, which in this case is raised up a bit from the mainlands. I’m pretty fond of the naked PCB approach to keyboard building, especially when they’re stacked and look as good as these do.

While the full split only comes in RP2040 (not that there’s anything wrong with that), the monoblock split is available in Pro Micro, ATmega Mini, and RP2040 versions. You can find the STL for the tilt stand and other goodies on Thingiverse.

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.

Keebin’ With Kristina: The One With The Pumpkin Keyboard

November 8, 2022 by 9 Comments

Oh, the places plastic has taken us. One of the arguably better inventions might be the fake carve-able pumpkin, which is more or less guaranteed not to shrivel up and rot on your porch, though it might get smashed by wily teenagers along with its organic brethren next door.

Though they will be around much longer, the fake kind lend themselves to all kinds of creations, including this one from [BunkEbear] which was “a nightmare” to build. Yeah, we bet it was along the lines of [Aaron Rasmussen]’s spherical keyboard, except inside out, since that one’s concave.

This tasty keyboard is modeled after the Malling-Hansen writing ball, which is arguably the first commercial typewriter and dates to 1865. [BunkEbear]’s pumpkin version features the 54-key layout, plus two additional for Shift and Escape to suit modern needs. Since the inside of the pumpkin is pretty small, [BunkEbear] wired all the connections close together on the protoboard, and used JST extension cables between the Glorious Panda switches themselves and the Arduino Pro Micro.

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.

Keebin’ With Kristina: The One With The Really Tall Keycaps

March 14, 2022 by 5 Comments

About a month ago, [Unexpected Maker] finished their TinyS3, an ESP32-S3 development board. Since the chip supports both true USB and Bluetooth, [deʃhipu] wondered how well it would work in a keyboard.

Thus, the Vegemite Sandwich was made, perhaps while [deʃhipu] was dreaming of traveling in a fried-out Kombi. But really, it was named so because [Unexpected Maker] hails from Australia.

This is [deʃhipu]’s first time using switch sockets, which is (as far as we know) the only choice when it comes to hot-swappable Kailh chocs. We’ll be watching this one with hungry eyes.

Keebin’ With Kristina: The One With The Ballpoint Typewriters

So you want to minimize finger movement when you type, but don’t have three grand to drop on an old DataHand, or enough time to build the open-source lalboard? Check out these two concept keebs from [SouthPawEngineer], which only look like chord boards.

Every key on the home row is a five-way switch — like a D-pad with straight down input. [SouthPawEngineer] has them set up so that each one covers a QWERTY column. So like, for the left pinky switch, up is Q, right is A, down is Z, and left is 1. Technically, the split has 58 keys, and the uni has 56.

Both of these keebs use KB2040 boards, which are Adafruit’s answer to the keyboard-building craze of these roaring 2020s. These little boards are of course easy to program with CircuitPython, which supports KMK, an offshoot of the popular QMK. Thanks for the tip, [foamyguy]!

Keebin’ With Kristina: The One With The Tri-lingual Typewriter

January 18, 2022 by 5 Comments

Isn’t it just fantastic when a project finally does what you wanted it to do in the first place? [Simon Merrett] isn’t willing to compromise when it comes to the Aerodox. His original vision for the keyboard was a wireless, ergonomic split that could easily switch between a couple of PCs. Whereas some people are more into making layout after layout, [Simon] keeps pushing forward with this same design, which is sort of a mashup between the ErgoDox and the Redox, which is itself a wireless version of the ErgoDox.

The Aerodox has three nRF51822 modules — one for the halves to communicate, one for the control half to send key presses, and a third on the receiver side. [Simon] was using two AA cells to power each one, and was having trouble with the range back to the PC.

The NRFs want 3.3 V, but will allegedly settle for 2 V when times are hard. [Simon] added a boost converter to give each a solid 3.3 V, and the Aerodox became reliable enough to be [Simon]’s daily driver. But let’s go back to the as-yet-unrealized potential part.
