 Hey folks, this week we're making accessibility keycaps for mechanical keyboards. These keycaps are 3D printed with the Burl alphabet so folks can touch to feel their keyboard shortcuts. We thought it'd be nice to have audio feedback so a tone is played when a key is pressed. The Adafruit Macro Pad features the RP2040 chip and has a built-in speaker for generating tones and playing audio files. The keycaps are compatible with Cherry MX and Kalebox switches. You can print the keycaps in one piece or just the top cover for existing keycaps. The keycaps are installed by press-fitting them over the stem of your favorite mechanical key switch. We think the resolution and print quality is good enough for making these style keycaps. Braille is a writing system that features raised bumps called cells. To make these keycaps, we reference this peel-and-stick overlay that features function keys and special characters. The Adafruit Macro Pad is great for making custom input devices for accessibility projects. This uses the CircuitPython Macro Pad library to make customizable shortcuts with lights and sounds. The main loop checks for key events and handles if it's a key code or consumer control such as volume and media playback. The shortcuts are stored in a separate file that contains a dictionary of keys. Here you can set the tone, label, keycode type, and key sequence. With CircuitPython you have access to the code with the USB drive which is great when developing across different computers. We hope you're inspired to check out the Adafruit Macro Pad RP2040 and use CircuitPython in your next project.
