Building a Teensy Groovebox (or Something Like It)

Putting together one of these devices and talking about how the hardware works. And some other stuff too idk this video kinda got away from me boys. For a more detailed writeup about the hardware and the build process, check out the Development Parts 3 and 4 pages linked below. This is an update in my DIY OP-1 inspired portable groovebox project, and clearly there are still many improvements to be made. To follow my progress as I add more functionality, to download code/hardware files, or for more information on this device, check out the following links.
