These work by using high-frequency sound waves to pound the surface of the water with mechanical energy. Some cool-mist humidifiers work by flinging water at a vaporizer, but our favorite kind uses a piezoelectric transducer.
Or twelve.Ĭontinue reading “Lo-Fi Fun: Beer Can Microphones” → Posted in classic hacks, Featured, Interest, Slider Tagged contact mic, mic, microphone, piezo, piezo disk, piezoelectric In flipping through the book, I noticed the beer can microphone project and was immediately taken by the aesthetic of some cool old 70s beer can with a 1/4″ instrument jack on the bottom, just asking for some dirty blues to be belted into it. Among my early choices was Making Poor Man’s Guitars by Shane Speal, who is widely considered to be the guru on the subject. Having never built a cigar box guitar before and being of a certain vintage, I’m inclined to turn to books instead of the Internet, so I stocked up from the library. I happily picked one up and started scheming on the way home. Bam! It’s sturdy, it opens easily, and it’s (very) roughly guitar body shaped. (Where else are you going to get a bunch of egg cartons without eating a bunch of eggs?) I noticed that they happened to also stock ammo boxes.
In trying to decide a suitable body for the slapdash guitar I was about to build, I found myself at a tractor supply store for LEGO-related reasons. A couple months back, I was looking at my guitars and guitar accessories and thought, it is finally time to do something with the neck I’ve had lying around for years. Sometimes, you just need an easy win, right? This is one of those projects.
