Ever since posting my previous LEGO keyboard a few years ago, which was built around an old membrane keyboard, I’ve wanted to build a version using mechanical key switches. This year, I finally ordered myself a mechanical keyboard to use as a base – a Cooler Master Quick Fire Rapid. It’s a pretty basic donor keyboard, but that’s all I wanted since my focus was going to be on the LEGO styling of it.
I built a pretty simple LEGO frame to house the circuit board and recruited my brother Roman, who is a mechanical engineer, to design some Cherry MX LEGO compatible key caps to mount on the switches. Check the video out to see it in action and how it is built. More details, photos and info about the key caps can be found below.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
