In this article we discuss a simple circuit which can used to synthesize music by blowing a MIC with breath power from mouth. The air pressure and vibration generated by […]
2 in 1 Light Dimmer Circuit with Touch Pad Operation
Dimmer circuits are always very popular. The twin dimmer offers two independent controls in one unit. A type S576 provides control of each section of the circuit. S576 is an […]
3 LED Running Light Circuit
In this post we learn how to make a running light or chasing light effect using only 3 LEDs, because 3 LEDs are the minimum number required for creating a […]
Designing a MOSFET Power Amplifier Circuit
We know that a design using complimentary emitter follower transistor significantly increases the output power of an operational amplifier. Similarly for achieving highly increased output power MOSFETs amplifier can be […]
Designing Large LED Dispay Circuit
First of all, this project will not seem interesting to every reader. But, this has many possible applications. This is a seven segment display, with a diameter of 280x140mm. The […]
Universal LED Bar Graph Indicator Circuit
This universal pointer or LED bar graph indicator circuit can be used with any kind of input sensor that delivers a exponentially varying voltage. This can be for example from […]
