This simple circuit can be used to emulate the operation of a music box. The number of notes may be limited to 10 at the most, and therefore is capable of generating a simple melody. By: Akanksha Rathode Circuit Operation The circuit uses two popular integrated circuits: The timer 555 and 4017 decade counter Operation […]

Music Triggered Amplifier Speaker Circuit
The circuit idea I have explained below enables a power amplifier loudspeakers to switch ON only when there’s an input music available, otherwise it makes sure that the loudspeakers remain shut off. The idea ws requested by Mr. David Alda. Technical Specifications Your site is just awesome. I’m hoping you can post a tweak to […]
Music Power Level Indicator Circuit using IC LM3915
In this post I have explained a LED music power level indicator for indicating a subwoofer bass power range, which can be also modified as an effective dancing Electroluminescent Wire light show. The idea was requested by Mr. David. Technical Specifications Here’s an idea or suggestion for your projects or what ever lol My son […]
Audio Dithering Circuit for Enhanced Crisper Music
In this article I have explained a simple circuit concept which can be used to transform an ordinary analogue audio signal into a much vibrant and crisper digital music, by adding an external random noise to the audio, which is also known as pink noise. Video dithering is a procedure for generating an image file […]
Digital Theremin Circuit – Make Music with your Hands
Named after its creator, the theremin originated in the Soviet Union in the beginning of 1920’s. This comprised of a container installed with a couple of antennas. It did not have any keyboard to play, no strings like in guitars. Rather, the theremin made use of human body capacitance to manipulate the volume and the […]
Simple LED Music Level Indicator Circuit
An LED music level indicator is a circuit that will respond to the connected music levels and illuminate a chain of LEDs sequentially in a push-pull switching manner, in accordance with the varying music intensity. Since the illumination level of the switching LED chain appear to extend forward and backward proportionately in response to the […]
