Body-ultrasound Sonography With Arduino

My hobby and passion is to realize physics projects. One of my last work is about ultrasonic sonography. As always I tried to make it as simple as possible with parts you can get on ebay or aliexpress. So let's take a look how far I can go with my simple items... I was inspired by this a bit more complicated and more expensive project: https://hackaday.io/project/9281-murgen-open-sourc... Here are the parts ...

Weather Based Music Generator (ESP8266 Based Midi Generator)

Hi, today I'll explain how to make your own little Weather based Music generator. It's based on an ESP8266, which is kind of like an Arduino, and it responds to temperature, rain and light intensity. Don't expect it to make entire songs or chord progressions. It's more like Generative Music people sometimes make with Modular Synthesizers. But it's a little less random then that, it does stick to certain Sca ...

Sound Detection RGB Lamp Using Arduino

Hello, In this project I am making a lamp with multiple colors using RGB leds. My idea is to try to let the lamp change color if it detects a sound in the area. If you get annoyed from the changing colors every time you make a sound, you can always put the lamp on a mode where you can change the colors manual. Also the lamp will go off when you come too close to it. The casing of the lamp is designed using ...

How to Make a Cheap Arduino MIDI Controller

I'm a huge fan of technology and music, but when I decided to start making my own electronic music, I was discouraged by the high price of MIDI keyboards and controllers. After a lot of tinkering, I saw the opportunity to create my own MIDI keyboard using an Arduino Uno and electric paint, for a fraction of the price compared to existing MIDI devices! In this tutorial, I will explain and show you how to cre ...

Simple Audio Amplifier

In most cases first project in electronics for beginners is building simple audio amplifier. That is because it requires small number of elements and not a lot of knowledge to build one. For low power amplifiers we could use integrated circuits like TDA family. But I will show how to make amplifier using operational amplifier. This amplifier is only to proof the concept. It real use can be as preamp for gui ...

LilyPad Arduino Painted Canvas With Music and Lights

This is a project that I created for my Children and Technology class that I am taking in my Masters of Library Science Program. This was one of my first experiences with coding so this was a trial and error process but this instructable should outline my success throughout the process. My initial inspiration came from pinterest where I saw this canvas painting of song lyrics with lights. I decided to recre ...

Arduino Based Guitar Tuner

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words, “My hearing was no longer tuned ...
