In this post I have explained how an effective and efficient, yet very cheap, and stabilized bench power supply can be designed by any electronic hobbyist for

This is a project of a simple toggle switch circuit using a CD4017 IC. With this circuit any AC or DC electronic device can be operated with a single push button.

In this post I have explained the circuit for a simple, universal capacitive discharge ignition circuit or a CDI circuit using a standard ignition coil and a

500W MOSFET Amplifier Circuit ST3030 B&K Components incorporates a well-designed circuitry using high-quality transistors in each section.

Among the different existing inverter topologies, the full bridge or the H-bridge inverter topology is considered to be the most efficient and effective.

This video shows some of the sounds the Manis Iteritas can produce. The Manis is related to the Basimilus Iteritas Alter but produces very different sounds w...

Previously, Op-Amps were developed as analog mathematical calculations and have since been useful in many electrical designs

Figure shows a project of 5V 10A power supply. This power supply circuit can be used where high current 5V power supply is required. The circuit is using a well known LM7805 IC from LM78xx series

Come on, everybody does it.

This motion detection alarm circuit works by a PIR sensor detecting movement and then triggering a relay circuit that drives an alarm siren.

A very effective pure sine wave inverter circuit can be made using the IC 4047 and a couple IC 555 together with a few other passive components. I have

See/Learn these transformerless power supply circuits, use capacitors instead, it smaller and lighter than transformer. There are circuits as follows.
