Pico Chording Keyboard Is Simultaneously Vintage And New

On paper, chording — that’s pressing multiple keys to create either a single character or a whole word — looks like one of the best possible input methods. Maybe not the best for speed, at least for a while, but definitely good for conserving the total number of keys. Of course, fewer keys also makes for an easier time when it comes to building keyboards (as long as you don’t have to code the chording software). In fact, we would venture to guess that the hardest part of building your own version of [CrazyRobMiles]’s Pico Chord Keyboard would be teaching your fingers how to work together to chord instead of typing one at a time.

[CrazyRobMiles] took inspiration from the Cykey chording design used for the Microwriter and later, the Microwriter Agenda that also featured a qwerty blister keyboard. Both featured small screens above the six keys — one for each finger, and two for the thumb. While the original Microwriter ran on an 8-bit microprocessor, Pico Chord Keyboard uses — you guessed it — the Raspberry Pi Pico.

We love that [CrazyRobMiles] went with four 14-segment displays, which gives it a nice old school feel, but used transparent keycaps over Kailh switches. This is actually important, because not only do the LEDs show what mode you’re in (alpha vs. numeric vs. symbols), they also teach you how to chord each letter in the special training game mode. Be sure to check it out in the video after the break.

Isn’t it cool that we live in a world of relatively big keyboards with few keys and tiny keyboards with all the keys?

Pomodachi: A Productivity Pet You Feed By Working

Being productive doesn’t have to be a lonely endeavor. Even if you’re a lone wolf, who wouldn’t benefit from having a cute little productivity pet to cheer them on? That’s the idea behind [droxpopuli]’s Pomodachi, which combines a hardware implementation of the Pomodoro technique with a virtual pet. It adds some fun, but doesn’t overly gamify time tracking to the point of distraction. And this is way more fun than just sticking a pair of googly eyes on a tomato-shaped timer.

Inside the box is an Adafruit HalloWing M4 Express and a NeoKey FeatherWing with two Kailh box white switches for a satisfying clack. [droxpopuli] printed up a PyPortal-inspired case and added a glass lens for a spiffy tube TV look.

Pomo himself is a cute little jack-o-lantern looking creature with a teddy bear face and no arms or legs. He could eat with his face, but prefers to be fed. That’s where you come in. You feed him by completing a set of four 20-minute work intervals.

Don’t worry about keeping track of time, because he does that for you and spends the time foraging for food. When it’s break time, Pomo lets you know and suggests an activity. This is when you press the button and feed him. If your productivity begins to flag a bit, don’t freak out — there’s a multiplier for catching up, and you have seven chances before Pomo runs away forever.

The Pomodoro Technique is pretty great for productivity, and it’s versatile, too. Here’s a hydration-based Pomodoro that will flood your desk if you don’t drink enough water.

Clacker Hacker: Hot Rod Switch Mods

Whether you’re a programmer, gamer, writer, or data entry specialist, the keyboard is an extension of your nervous system. It’s not so much a tool as it is a medium for flow — for being in the zone. So I think it’s only natural that you should care deeply about your keyboard — how it looks, how it sounds, and above all, how it feels to finger-punch those helmeted little switches all the live-long day. That’s my excuse, anyway.

It might surprise you that mechanical keyboard switches can be modified in a number of ways. Depending on what you want from your keyboarding experience, you can make switches feel lighter or less scratchy, quiet them down, or tighten up any wobble in the housing. Why would you want to do this? Because customization is fun. Because electromechanical things are awesome, and because it’s fun to take switches apart and put them back together again. Because it’s literally hacking and this is Hackaday.

This is a pair of plates from a macro keeb I’m making that will sit directly in front of my trackball.

I got into switch modding because I wanted to put Cherry clears in my dactyl, but worried that they would take too much force to actuate and wear my fingers out. So I bought some really light (39g) springs and was really looking forward to swapping them into the clears, but they just don’t work. Like, physically. Slider goes down, slider gets stuck. It will come back up, but only if I hit it again and smear my finger to the side a bit at the same time. Those springs must be too weak to return clear sliders.

I took this as a sign that I should suck it up and use browns instead. After all, no one else has to know what my sliders look like. While I was opening switches, I tried out one of these super-light springs in a brown, thinking maybe they wouldn’t have to go to waste. Not only did the lighter spring work in the brown, it felt pretty nice. It’s hard to imagine how a whole keeb would feel based on a single switch, but if you can gather a handful and snap them into a plate to riffle your fingers over them, well, it’s probably close enough to a full keyboard to get a good feel for whatever mod you’re doing.

Sherbet Custom Game Pad Is Smooth And Sweet

When [Billiam]’s beloved Logitech G13 game pad went to that great spectate room in the sky, he decided to pay homage by designing a custom, more ergonomic replacement from the desk up. Grab a spoon and dig into the story of [Billiam]’s journey toward Sherbet, because it’s a sweet ride.

Here’s the scoop: like a lot of DIY game pads and keyboards, Sherbet is based on the Teensy. We often see the micro USB coming straight off the Teensy, especially in clear acrylic builds, but [Billiam] added a USB breakout board so there’s no direct stress on the Teensy itself.

One of [Billiam]’s design challenges comes from the game pad placement — he has a tall desk and uses a keyboard tray, so it has to fit the space and leave enough room for his hand. Fortunately, there are low-profile mechanical switches out there, although the keycap options are strongly limited. We love that [Billiam] embedded a tiny ceramic bearing into one of them to use as a homing bump, because that’s a great idea.

If you want to take a crack at this project, [Billiam] has all the goodies laid out. [Billiam] wanted to use QMK firmware, but they didn’t have joystick support yet, so he’s got an Arduino sketch running in the meantime.

We love a good custom game pad around here, especially if they can reprogram themselves.
