Davehax: Microphone construction may seem quite complicated as the technology used is not accessible. But with the steps below, you can easily make microphones inside your home using pencil toner and a matchbox.
You'll also need a few other things like a 9 volt battery, some basic cables, alligator clips, and a speaker or headphones.
The construction presented by YouTuber Davehax is outrageously simple.
Just remove the lead from your pencils very carefully, scrape one flat side on each, place them in the matchbox as shown in the video below, and you're ready to wire.
The effect may not look as nice as the microphones of a studio microphone, but it works surprisingly well!
