Want a neat, but functional item to add to your desk? Check out this cool design for an old school microphone that’s made from cardboard, but actually works.

YouTuber SKM builds lots of fun stuff from cardboard, and this is definitely one of his coolest designs. It looks just like one of those old microphones that a news broadcaster or radio personality might speak into. I really dig the way that he wrapped the cord in strips of cardboard too.

Once you watch the video, you’ll see that it’s not that complicated to build, but it will take a little time, patience, and the requisite hot glue strings burns on your fingertips to complete:

The working part of the microphone is just an off-the-shelf, modern lavalier mic, so it’s really just a cardboard microphone sculpture with a microphone inside. Still, it’s really neat, and I’d like a whole set of cardboard electronic gear in my office.
