Keebin’ With Kristina: The One With All The LEGO

December 20, 2023 by Kristina Panos 3 Comments

It seems like mechanical keyboard enthusiasts are more spoiled for choice with each passing day. But as broad as the open source pool has become, there’s still no perfect keyboard for everyone. So, as people innovate toward their own personal endgame peripherals and make them open source, the pool just grows and grows.

This beautiful addition to the glittering pool — [Bo Yao]’s Carpenter Tau keyboard — is meant to provide an elegant option at a particular intersection where no keyboards currently exist — the holy trinity of open source, programmable, and tri-mode connectivity: wired, Bluetooth, and 2.4 GHz.

Come for the lovely wooden everything, and stay for the in-depth logs as [Bo Yao] introduces the project and its roots, reviews various options for the controller, discusses the manufacture of the wooden parts, and creates the schematic for the 61-key version. Don’t want to build one yourself? It’ll be on Crowd Supply soon enough.

Keebin’ With Kristina: The One With The Biblically-Accurate Keyboard

December 7, 2023 by Kristina Panos 5 Comments

Well, it was bound to happen at some point. [sporewoh]’s bunchiez40 keyboard for ants is made of mouse switches, which of course begs for a mouse made of keyboard switches.

[sporewoh]’s keyboards have been steadily shrinking, and they built this in order to get the smallest possible form factor for the number of keys. Surprisingly, since the mouse switches have an actuation force similar to some heavier MX-style switches (~70 g), [sporewoh] is able to squeeze 85 WPM out of it, albeit with some argument from the wrists.

If you want to build a bunchiez40, everything is available on GitHub, including the CAD files for that lovely anodized aluminium case. The typing video is coming soon, and I’m taking bets on whether it’s as quiet as a mouse, as one redditor joked.

Keebin’ With Kristina: The One With The Duplex Typewriter

November 21, 2023 by Kristina Panos 10 Comments

The Coleco Adam? A not-so-great home computer that likely contributed to the downfall of the company. The keyboard, however, is a different story, and worth repurposing.

[Nick Bild] has created a USB adapter that uses a Teensy 4.1 and an RJ-12 breakout board. Now this wasn’t just a simple matrix to decode. No, the fine folks at Coleco rolled their own communications protocol called AdamNet.

The keyboard uses an RJ-12 connector and a single data line to communicate over a 62.5 kbit/s, half-duplex serial bus. Inside the keyboard is a Motorola 6801 that caches the key presses and sends them to the computer. So the BOM is limited to what you see above — an RJ-12 breakout and a Teensy 4.1. It’s great to see old keyboards come alive again, especially one with such cool sci-fi keycaps. Want to hear it clack? Of course you do.

Keebin’ With Kristina: The One With The Foot Keyboard

October 25, 2023 by Kristina Panos 12 Comments

[crispernaki]’s opening comments to this VCR head scroll wheel project lament that overall technical details aren’t “complex, ground-breaking, or even exciting.” Since when does that matter? The point is that not only did the thing finally, eventually get built, it gets daily use and it sparks joy in its owner.

This feel-good story is one of procrastination, laziness, and one aha! moment, and it’s roughly twelve years in the making. Inspired by an Instructable from long ago, [crispernaki] ran straight to the thrift store to get a VCR and take it apart.

The original plan was to just reuse the VCR head’s PCB and hide it in an enclosure, and then figure out way to block and unblock the path between an IR emitter/receiver pair. After many disemboweled mice and fruitless attempt, the project was once again shelved.

But then, [crispernaki] remembered the magnetic rotary encoder demo board that was just sitting around, along with various microcontrollers and Altoids tins. And it all quickly came together with a Teensy 2.0 and some bits and bobs, including a magnet glued on the shaft of the VCR head. A chip on the demo board does all the heavy lifting, and of course, the Teensy does the work of emulating an HID.

Keebin’ With Kristina: The One With The Tile-Based Macropad

October 16, 2023 by Kristina Panos 8 Comments

Prolific Hackaday.io member [Michael Gardi] has hit upon the biggest problem with making reprogrammable macro pads — the legend situation. What do you do when the whole point is that the keys can so easily be changed?

There are a couple of options: blank keycaps and memorization, re-legendable keycaps, and little screens instead of keycaps. Surely there has to be another way, and [Michael] has discovered one: a tile-based system of descriptors.

As you can see, the labels are removable 3D-printed tiles that swap out with ease thanks to tiny magnets. But these aren’t just tidy labels. Inserting a new label automatically changes the macro! Each tile holds a “simple numeric value” which maps it to a macro when inserted and detected by a Hall effect sensor. I can’t wait to hear these tiles click in action during a demo video, which I can only hope is forthcoming.

Keebin’ With Kristina: The One With The Arboreal Keyboards

October 9, 2023 by Kristina Panos 6 Comments

Well, unfortunately we don’t know much yet about this nice wooden keyboard from [Kelvin Chow], but maybe this inclusion will encourage [Kelvin] to post more about it.

Sure is nice-looking, don’t you think? That’s because there some great details at play here, like the legend-less two-tone keycaps and the neat-o locking box it sits in.

This keyboard is inspired by the Hacoa Ki-board, which uses a singles plank of wood to craft the keycaps. [Kelvin] wanted to try this technique for themselves. Evidently this won’t be the last wooden keyboard, so stay tuned for more over on Hackaday.io.

This isn’t the first dead-tree keyboard we’ve seen around here, either. A while back we saw one with Scrabble tile keycaps, and earlier this year, a nice wooden macro pad.

Keebin’ With Kristina Hack Chat

September 25, 2023 by Dan Maloney 3 Comments

Join us on Wednesday, September 27 at noon Pacific for the Keebin’ with Kristina Hack Chat with our own Kristina Panos!

When you think about it, wiggling your fingers over a bunch of magic chiclets is a pretty strange gateway to the written word. And yet, here we sit a hundred-odd years after someone first decided that the same basic interface used to run pianos and harpsichords for centuries would be a fantastic model for mechanizing the whole writing thing. Just because it makes perfect sense thanks to the outsized portion of our brains dedicated to the motor and sensory functions of our wonderfully complex and versatile hands doesn’t mean it’s not weird.

Still and all, it seems like there could be some room for improvement in the basic design of keyboards. We could probably do with something that makes typing easier, results in less repetitive strain, or is just more fun to do. Pushing back on the traditional and boring designs of the past is where we find the strange breed of keyboard builders and modders that our very own Kristina Panos counts herself part of. You know here from her popular “Keebin’ with Kristina” series, and now we’ve coaxed her into checking into the Hack Chat to talk to all the rest of us keyboard-minded individuals. If you’ve ever thought that there has to be a better way to enter text, or even just something a little bit different, you’ll want to come along and join the conversation.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, September 27 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.
