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 ...

A POCKET QWERTY FOR ARDUINO AND MORE

If you want to add a keypad to your Arduino project, the options are pretty limited. There’s that red and blue 4×4 membrane we’ve all seen in password-protected door lock projects, and the phone layout version that does pretty much all the same tricks. Isn’t it time for a full Arduino-compatible keyboard? [ELECTRONOOBS] thinks so. This 41-button Arduino keyboard PCB is a stepping stone to his next proj ...

A KEYBOARD INTERFACE FOR YOUR SINCLAIR ZX

The SInclair ZX 8-bit computers of the early 1980s were masterpieces of economy, getting the most out of minimal hardware. The cassette tape interface was a one-bit port, the video was (on the first two models anyway) created by the processor itself rather than a CRT controller, and the keyboard? No fancy keyboard controllers here, just a key matrix and some diodes between a set of address lines and some da ...

A MACRO KEYBOARD IN A MICRO PACKAGE

Remember back in the early-to-mid 2000s when pretty much every cheap USB keyboard you could find started including an abundance of media keys in its layout? Nowadays, especially if you have a customized or reduced-sized mechanical keyboard, those are nowhere to be seen. Whenever our modern selves need those extra keys, we have to turn to external peripherals, and [Gary’s] Knobo is one that looks like it cou ...

USB NeXT Keyboard with an Arduino

Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! However, they are very old designs, specifically made for NeXT hardware, pre-ADB and pre-USB! That means you can't just plug the keyboard into an ADB or PS/2 port or PS/2 to USB converter (even though it looks similar). In fact, I have no ...

Extra inputs for Arduino with a keyboard

The Arduino is perhaps the coolest thing on earth. There are many types, the Uno, the Mega, the Pro, the Pro Mini, etc. etc. But one thing that often can be a problem is that you only have a limited number of inputs and outputs. There are many solutions for that, ranging from multiplexers to port expanders. But one thing that gives you up to 171 extra inputs is to use an old keyboard. And that is that this ...
