Ultrasonic range finders are fun little modules that measure distance. You can use them to find the distance to an object, or to detect when something is near the sensor like a motion detector. They’re ideal for projects involving navigation, object avoidance, and home security. Because they use sound to measure distance, they work just as well in the dark as […]

Jeopardy style quiz games are favorites for creating excitement and educational instruction at the same time. Teachers, summer camp counselors, and even industry educators find this type of game to help generate interest and involvement from the participants. The idea behind the game is simple, but sometimes finding a device that will perform the “first

A team of researchers at the ‘Georgia Institute of Technology’ has come up with a non-invasive sensor-in-a-chip that records details of the heartbeat, respiration rates, and lung sounds. It even tracks the wearer’s physical activities, such as walking. The signals are recorded in sync, potentially giving healthcare workers a detailed overview of a patient’s heart and lungs.

This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Creating emergent patterns that can be converted into sounds fascinates me. So this is my first experiment in building an arduino platform for creating such patterns. This version uses a Gameduino as its

Where I live, from spring to autumn we have to compete for territory against tiger mosquito. Local stores offer a impressive list of anti mosquito devices, candles, including sophisticated traps sold a few hundred euros, I even found one sold 2000€ – this give you an idea of how desperate people are to get rid

Most vacuum tubes need about 6.3V high supply plus filament voltage to operate. Running at 3.3V inclusively of the filament voltage, the new vacuum tube amplifier from Albert van Dalen has proven it possible to have one with the capacity to operate on an entirely low power supply voltage and still work well. To be able to

In theory, it is quite simple to perform sound localization by measuring the phase difference of signals received by two microphones that are far apart in space. The devil is always in the details. I have not come across any project made for Arduino like this before, and I am wondering if it is even

I’ve just completed my second Arduino project, a sound level detector which sets off an “alarm” when there’s the sound level is to high for too long. I built it for use in a school that wants to provide visual feedback to students when they are being too loud. The “alarm” is a string of

What is it about solenoids that makes people want to make music with them? Whatever it is, we hope that solenoids never stop inspiring people to make instruments like [CamsLab]’s copper pipe auto-glockenspiel. At first, [CamsLab] thought of striking glasses of water, but didn’t like the temporary vibe of a setup like that. They also considered
