Project Spotlight: “3D-Printed Mouse” Circuitry & Design

I get to meet and interact with creative engineers and researchers around the world who are working on innovative MCU-based projects. Some of them show up at our office to chat. Others I meet with when I travel to California for events like the Embedded Systems Conference. But many of the most interesting people and projects I find are on the Net. A perfect example is David Mellis, whose projects and research grabbed my attention recently while I was browsing the MIT Media Lab website. He is a PhD student in the High-Low Tech research group at the MIT Media Lab.

Mellis gave me permission to write about the projects and post some of the photos from his website, so let’s take a look at one of them—the “3D-Printed Mouse.”

Mellis writes:

This mouse combines a traditional electronic circuit board and components with a 3D-printed enclosure. The mouse is open-source: the original files necessary to make or modify its design are available for download below.
