One of the greatest joys of being a child was figuring out that rubber bands make awesome sounds when they are plucked, and that the sound is easily changed by stretching the band to different lengths. Reminds us of another way to easily reuse plastic soda bottles by making them into rope.Ĭontinue reading “Belt The Quarantine Blues Into A Homemade Mic” → Posted in classic hacks Tagged microphone, PETE, piezo disk Just clamp a razor blade into your vise and move jug against it. We like ’s method for cutting down the juice jug without cutting into yourself. Let us know in the comments after you check out ’s music video. This fun project is about as open as it gets, but we’re sure that you can think of ways around using a piezo disk. The piezo picks up the vibrations and sends them to a 1/4″ jack so you can plug it into an amp.Įven if you are somehow sidestepping the blues, you can always use this to yell at people who threaten to get too close to you. You do your shouting into the other end, and your sound waves vibrate the membrane. The plastic gets heat-fused to the rolled edge of the can, and since it gets stretched and shrunk in the process, it forms a tight membrane that doubles as a percussion instrument. If you’re running out of ideas, or just want to feel better by doing some in-house recycling, dump out that bin and make a simple microphone.Īll you need is some PETE #1 plastic, a piezo disk, and the right kind of tin can. If there’s any psychological good to be gleaned from quarantine, it’s that people are using the time to finish old projects while starting plenty of new ones. They’re not picky about where the water comes from, so if you have enough of them, you can dry a load of laundry in a few minutes.Ĭontinue reading “Cool Off With A Piezo And A Glass Of Water” → Posted in home hacks, Science Tagged 555, atomizing transducer, cool mist, humidifier, mosfet, piezo, piezo disk, transducer, ultrasonic atomizer Check out the demo and build video after the break.Ītomizing transducers can do way more than than moisten the air for our comfort. The circuit is designed for atomizing transducers, which have a resonant frequency of 113 KHz - much higher than your average junk box piezo. You don’t need much more than that and a handful of passives to recreate this cool junk box experiment, but the spec of the piezo disk is quite important. ![]() The driving circuit for this DIY mist maker uses a 555 to generate 113 KHz, a trimmer potentiometer to fine-tune it, and a MOSFET to amplify the signal. That energy introduces standing waves that force the water to break apart into a fine mist on the surface of the piezo disk. 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. ![]()
