In this project we will see how to build a pair of glasses in which the circuits for Bluetooth headsets are inserted in the frame. Therefore you can listen to music wirelessly while wearing. The circuit consists...

In the world of homebrew synthesizers, there are plenty of noiseboxes and grooveboxes that make all kinds of wacky and wild noises. However, common projects like the Auduino and Atari Punk Console are often limited in that...

https://youtu.be/Sn2sbEnmoYk In this project I have designed a remote WiFi Controlled Audio Source Selector Switch (Wi-CASSS) with a ESP8266 board which enables the user switch between two connected input/output audio devices over internet. Hence this removes the...

Max Williams has just shared on Hackster.io schematics, PCB layouts, CircuitPython code via GitHub, BoMs, measurements and photos about his new open source modular HiFi amplifier. It uses an Adafruit ItsyBitsy M0 Express running CircuitPython to make great music. The preamplifier...

  Based on the ISD1730 chip, this card allows you to record and play voice messages of up to 20 seconds. The card has a microphone, audio input, 8 ohm speaker, AUX output, function control buttons and...

  It is based on the DFRobot module, and enables the playing of musical tracks that have been recorded on a microSD or on a USB Pen Drive; it is supplied with outputs that enable to connect...
