Custom Controller Box
In this project, you'll learn how to build a basic USB HID keyboard for triggering things like commands and hotkeys for controlling any number of software and hardware. We'll use an Adafruit Feather M0 Express, a handful of arcade buttons and Circuit Python to make a DIY keyboard controller.
Circuit Python makes this project super simple to program and easy to update - no need for a compiler, IDE, or any special drivers. Just plug it in and open up the text file in the virtual USB key to reprogram the keys whenever you want.
When this box is connected to your computer, it behaves just like a USB HID Keyboard. Press a button and it types a letter! It's really simple and easy to manipulate the software so you can output single characters, or string multiple characters together to execute commands! The LEDs also light up each time you press a button. Sound like an interesting project? Let's get started!
Prerequisite Guides
If your new to electronics and the Adafruit Feather M0 Express, I suggest you walk through the following guides to get the basics. The Adafruit Feather M0 Express guide will walk you through setting it up with CircuitPython.
3D Printed Case
All of the components will be housed in a 3D printed box. It's a two-piece design that features a "snap-on" cover. The cover is specifically designed to house the Adafruit Feather boards using two machine screws. The CAD model is parametrically driven, so it's easy to modify the design.
No 3D Printer? No Problem!
If you don't have access to a 3D printer, we suggest checking out a 3D printing service like 3DHubs.com. There, you can search and find a local maker who can print the parts and ship them to you! Just download the STLs and upload them, you can browse through a list of local 3D printer operators and choose your material and the color you want the parts to be printed in.
Ideas, Ideas, Ideas!
Game Controller
Make an arcade style game controller to play retro games. These are after all, arcade buttons! They're fun to press and work well for game controllers.
Media Editing Controller
Use this to quickly switch scenes in wirecast, change cameras in adobe premiere or final cut pro. Execute shortcut keys, commands, tools and other handy things with a push of a single button.
Assistive Technology Switch
With easy to press buttons and large surface area, this could be quite handy for AT projects. Make a custom project to trigger any number of systems and applications.
