For a lonely person, elderly or otherwise, the sound of a ringing phone can be music to the ears, unless of course it’s another spam call. But what good is a phone when you can’t hear it well enough to answer? [Giovanni Aggiustatutto] was tasked with building an additional ringer for a set of cordless landline phones […]

Want to play the xylophone but don’t want to learn how? [Rachad]’s automatic xylophone might be just the ticket. It uses homemade solenoids to play tunes under computer control. Think of it as a player piano but with electromagnetic strikers instead of piano keys. You can hear the instrument in action in the video below.

We absolutely love the impetus of this project, as it definitely sounds like something a Hackaday reader would go through. After finally deciding between a CNC router and a laser cutter, [Eirik Brandal] was planning to “Hello, World” the CNC with something quick and simple, like maybe a few acrylic plates with curves and some

The limited funding and job opportunities in the humanities field make it challenging for emerging scholars to pursue additional knowledge. As scholars must acquire extensive knowledge within their respective disciplines, they must also create coherent projects within an academic context. This situation creates difficulties for educators to learn and develop technology-related curriculum. However, there is
Making Sounds with Arduino Continue Reading
One quick fore note: this is my first Instructable and my first large Arduino project, so if you see any stupid errors or have an idea of how things could be done better, then please let me know. Now that that’s out of the way I’ll begin, I started designing this around September last year as my A2

Description Clap switch/Sound-activated switch designed around op-amp, flip-flop and popular 555 IC. Switch avoids false triggering by using 2-clap sound. Clapping sound is received by a microphone, the microphone changes the sound wave to electrical wave which is further amplified by op-amp. 555 timer IC acts as mono-stable multi-vibrator then flip-flop changes the state of

We’re used to seeing the Raspberry Pi crop up in a wide range of the projects we show you here, but it’s fair to say that they usually feature some sort of operating system. There’s another way to use a Pi, more akin to using a microcontroller such as the Arduino: by programming it directly,
BARE METAL GIVES THIS PI SOME CLASSIC SYNTHS Continue Reading
The kit is available for ESP32 modules to offer developers cost-effective data transmission via sound waves. Chirp, the pioneers in data-over-sound technology today announced the launch of its new SDK for Arduino, providing developers with audio-based data transmission capabilities to enhance projects created on the platform. Now supporting ESP32 development boards, Chirp’s SDK for Arduino is available to use
CHIRP LAUNCHES SDK TO DELIVER DATA-OVER-SOUND FOR ESP32 ARDUINO PROJECTS Continue Reading
Every day of our lives we get bombarded with different sounds around. Loud music, radio, people talking on their phone, automobile, traffic, and those unknown late night quacking sounds. All of these sounds are what makes our day to day activities, and we have even gotten accustomed to most of them and rarely get disturbed by them.

I will describe a fun and easy way to build your own sound expression MIDI enabled glove without expending lot’s of money on MIDI Interfaces or expensive sensors. Feel free to contact me directly by mail if you like it or have suggestions. This project was inspired by other do it yourself projects using Piezo
