Arduino kaosillitaor

Kaosduino: Create your own kaosillitaor using Arduino

This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Inspired by Korgs Kaossilator I took it upon myself to build an opensource version of it. This way people can design new ways of interacting with the touchpad. The basic principle is creating […]

Adafruit Flora NeoPixel LED Ring Headphone mod

Adafruit Flora NeoPixel LED Ring Headphone mod

Wearable Arduino mod for your headphones. Non-invasive procedure for headphones that don’t have room inside the drivers or you don’t want to hack apart your high end cans. Adafruit just put out a tutorial for adding pattern blinking LED lights to headphones.  This instructable takes it one step further. This project is really the Adafruit Ampli-tie project morphed

Measuring Refrigerant Gases Sound Speed Using Arduino and App Inventor 2

Measuring Refrigerant Gases Sound Speed Using Arduino and App Inventor 2

The purpose of this Instructable is to build a portable device that can measure the speed of sound in refrigerant gases and use this data to identify them. The speed of sound in an ideal gas is related to two characteristics of the gaseous substance, its molecular mass (kg/mol) and its adiabatic constant (heat capacity ratio), or

Making the Grid

Creative Noise Semaphore

This project was submitted to ‘Creative Electronics’, a Beng Electronics Engineering module at University of Málaga, School of Telecommunications (https://www.uma.es/etsi-de-telecomunicacion/). It’s a modification based on sound level meters that are already marketed for use in classes to measure ambient noise. The project is developed in Arduino. It consists of a LED screen in which emoji

Voice Loudness Monitor Arduino

Voice Loudness Monitor (Arduino)

In this pandemic it is important to take reasonable measures to reduce spreading viruses. A paper from 2019 found that louder voices spread more viruses (https://www.nature.com/articles/s41598-019-38808-z) [Asadi et al. 2019]. This simple project aims to remind people to not shout unnecessarily. This can be used in classrooms, meeting rooms or any other setting where people
