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. […]
Childlike imagination is a wonderful thing. The ability to give life to inanimate objects and to pretend how they’re living their own life is precious, and not for nothing a successful story line in many movies. With the harsh facts or adulthood and reality coming for all of us eventually, it’s nice to see when

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
Quiz Game Controller using “Lights and Sounds Buzzers” and Arduino Continue Reading
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
Matrix sound machine: Generative music with a particle system using Arduino Continue Reading
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
Sound Localization using Arduino Continue Reading
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

Increasing noise levels have become a major issue in many urban areas today due to factors like population increases, urban development, and technological advancements. Moreover, excessive noise from a neighbor or colleague can seriously impact one’s well-being and quality of life. Conversations conducted at high volumes in office settings are understandably disruptive. Having a coworker
