Keebin’ With Kristina: The One With The Folding Typewriter

Have you built yourself a macro pad yet? They’re all sorts of programmable fun, whether you game, stream, or just plain work, and there are tons of ideas out there.

But if you don’t want to re-invent the wheel, [CiferTech]’s MicroClick (or MacroClick — the jury is still out) might be just what you need to get started straight down the keyboard rabbit hole.

This baby runs on an ATmega32U4, which known for its Human Interface Device (HID) capabilities. [CiferTech] went with my own personal favorite, blue switches, but of course, the choice is yours.

There are not one but two linear potentiometers for volume, and these are integrated with WS2812 LEDs to show where you are, loudness-wise. For everything else, there’s an SSD1306 OLED display.

But that’s not all — there’s a secondary microcontroller, an ESP8266-07 module that in the current build serves as a packet monitor. There’s also a rotary encoder for navigating menus and such. Make it yours, and show us!

Keebin’ With Kristina: The One With The Tasty Snacks Board

[MakerM0]’s LangCard is an entry into our 2024 Business Card Challenge that just so happens to fit the Keebin’ bill as well.

You might label this a pocket cyberdeck, and that’s just fine with me. The idea here is to have a full-keyboard development board for learning programming languages like CircuitPython, MicroPython, C++, and so on, wherever [MakerM0] happens to be at a given moment.

Open up the LangCard and you’ll find an RP2040 and a slim LiPo battery. I’m not sure what display that is, but there are probably a few that would work just fine were you to make one of these fun learning devices for yourself.

Raspberry Pi Pico Gets A Tiny Keyboard On Its Back

January 10, 2022 by Tom Nardi 25 Comments

With hackers and makers building custom computing devices that don’t necessarily follow conventional design paradigms, there’s been a growing demand for smaller and smaller keyboards. Many of the cyberdecks we’ve seen over the last couple of years have used so-called 60% or even 40% keyboards, and there’s been a trend towards repurposing BlackBerry keyboards for wearables and other pocket-sized gadgets. But what if you need something even smaller?

Enter this incredibly diminutive keyboard created by [TEC.IST]. With 59 keys crammed into an area scarcely larger than three US pennies, it may well be the smallest keyboard ever made. The PCB has been designed to mount directly onto the back of a Raspberry Pi Pico, which is running some CircuitPython code to read the switch matrix and act as a standard USB Human Interface Device. The board design files as well as the source code for the Pico have been released on the project’s Hackaday.io page, giving you everything you need to spin up your own teeny tiny input device.

The Pi Pico’s castellated pads make attaching the PCB a snap.

Of course, you probably won’t be breaking any speed records when banging out text on this thing. We know from past Hackaday badges that an array of microswitches make for a functional, if somewhat unpleasant, method of text entry.
