Everyone has a chip-of-shame: it’s the part that you know is suboptimal but you keep using it anyway because it just works well enough. Maybe it’s not what you would put into a design that you’re ...

The bipolar NE555 timer IC is widely used in inductorless dc-dc converters, most frequently in doubling and inverting converters. However, another very popular IC, the LM386 audio amplifier, may be a ...

Simple Mic audio amplifier can amplify sound that is given from Microphone. This circuit can be used as “Small mic and loudspeaker system” for a small space like a room. This circuit can also be used ...

Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...

This repository contains the KiCad project files for a simple audio amplifier based on the LM386 IC. This amplifier is designed for low-power audio applications and is suitable for use with small ...

This project is an FM receiver circuit radio based on Philips TEA5767 digital radio-receiver module. The radio receiver uses I2C interface with Arduino UNO development board. The TEA5767 module offers ...
