MAGNUM OPUS KEYBOARDUS, OR BUILD AD INFINITUM?

It happens to pretty much everyone who gets into keyboards. No commercial keyboard can meet all your needs, so you start building them. Use them a while, find problems, build a new keyboard to address them. Pretty soon you think you have enough user experience to design the perfect keeb — the be-all, end-all magnum opus clacker you can take to the grave. This time, it happened to [aydenvis]. We must say, th ...

CALCUINO IS AN ARDUINO CALCULATOR

All by itself, a calculator based on an Arduino isn’t necessarily very novel. However, [Volos] has a nice board that, of course, looks like a calculator. There are 16 keys and an LED display. But it seems to us the real value would be using this as a base for other projects. As an inexpensive development board, it’s handy to have a simple processor with a keyboard and a display. There’s some extra I/O pins ...

Arcade Button MIDI Keyboard

This is a version 2.0 of one of my first forays into Arduino and DIY MIDI programming. I've developed my skills in prototyping and design so I thought it would be a good demonstration of process and progression. With a more informed design process I recycled the buttons from my first attempt and set off to build 2.0! Step 1: Materials My 1st version used an Arduino Mega because of the many intputs it has bu ...

THE CLICKIEST KEYBOARD EVER

No matter how clicky your keyboard is, nothing compares to the sensory experience of using a typewriter. The sounds that a typewriter makes, from the deep clunk of hitting the spacebar to the staccato of keys striking paper to the ratchety kerchunk of returning the carriage, are a delight compared to the sterile, soulless clicks of even the noisiest computer keyboard. Oh, and the bell — who doesn’t love the ...

BABY KEYBOARD IS REALLY THREE BOARDS

Just when we think we’ve peeped all the cool baby keebs out there, another think comes along. This bad boy built by [andyclymer] can be configured three different ways, depending on what kind of control you’re after. As designed, the PCB can be used as a six-switch macro keyboard, or a rotary encoder with two switches, or a pair of rotary encoders. It’s meant to be controlled with Trinket M0, which means it ...

SLIPPY SLAPPER USELESSLY USES ALL THE ARDUINOS

Want to take that annoyingly productive coworker down a notch? Yeah, us too. How dare they get so much done and be so happy about it? How is it possible that they can bang on that keyboard all day when you struggle to string together an email? The Slippy Slapper is a useless machine that turns people into useless machines using tactics like endless distraction and mild physical violence. It presses you ...

EMULATING A BLUETOOTH KEYBOARD WITH THE ESP32

Most people associate the ESP family of microcontrollers with WiFi, which makes sense as they’ve become the solution of choice for getting your project online quickly and easily. But while the WiFi capability might be the star of the show, the ESP32 also comes equipped with Bluetooth; we just don’t see people using it nearly as often. If you’re looking to get started using Bluetooth on the ESP32, then this ...

IF YOU CAN’T BUY THE KEYBOARD YOU WANT, BUILD IT INSTEAD

The great thing about being a maker is that when the market fails to meet your needs, you can strike out on your own. [GuzziGuy] did just that, building a bespoke mechanical keyboard that’s stylish to boot. The aim was to create a keyboard well suited to working without a mouse, and with a keypad on the opposite side to suit a left-hander’s predilections. The case consists of an aluminium top plate with an ...

ROTARY DIAL BECOMES USB KEYBOARD

[Max] had a rotary dial from an old telephone and — unsurprisingly — had nothing in particular to do with it. The simple answer? Use an Arduino Leonardo to turn it into a USB keyboard device. Of course, the Leonardo can easily impersonate a USB keyboard, so that’s the easy part of the project. Interfacing to the dial requires an understanding of how the phone system works. While today, TouchTone phones ...
