Op amp Oscillators

In this post we learn how to design opamp based oscillators, and regarding the many critical factors required for generating a stable oscillator design. Op amp based oscillators are normally used to generate precise, periodic waveforms like square, sawtooth, triangular, and sinusoidal. Generally they operate using a single active device, or a lamp, or a … Read moreOp amp Oscillators

Arduino 3 Phase Inverter Circuit with Code

Arduino 3 phase driver

In this post we learn how to make a simple microprocessor Arduino based 3 phase inverter circuit which could be upgraded as per user preference for operating a given 3 phase load. We have already studied an effective yet simple 3 phase inverter circuit in one of our earlier posts which relied on opamps for … Read moreArduino 3 Phase Inverter Circuit with Code

Motorcycle Button Start Locking Circuit

In this post we discuss how to modify an existing button start system in motorcycles so that it’s disabled as soon as the engine has started and gained the required minimum amount of RPM. The idea was requested by Mr. Jordan Circuit Requirements I just discovered your splendid site/blog with focus on education about electronics. … Read moreMotorcycle Button Start Locking Circuit

Understanding Amplifier Circuits

In general, an amplifier can be defined as a circuit designed to boost an applied low power input signal into a high power output signal, as per the specified rating of the components. Although, the basic function remains the same, amplifiers could be classified into different categories depending on their design and configurations. Circuits for … Read moreUnderstanding Amplifier Circuits
