DIY Microphone

Little holder I made for this instructables microphone you can find here: https://www.instructables.com/Simplified-Electronics-Microphone-DIY-How-It-Works/

The instructables uses household materials, but i figured I'd just replicate it.

To be honest, I could not get this sounding as good as the author did, but it still produced a sound.

You can watch a video where I detail it here:
