Making a Strong RF Discharge Circuit
In this article we study an RF discharge generation concept also called EMP generator capable of producing an intense RF electrical discharge in the air which may have the potentials of paralyzing and permanently damaging all electronic systems in the close vicinity. The idea was requested by Mr. Nidal. Technical Specifications I have seen a […]
LCD Monitor SMPS Circuit
This power supply functions with a broad input voltage range from 90 to 265 V AC and produces a dual output in the form of 5 V / 2.5 A, and 14.5 V / 1 A. The Circuit Layout The great aspect of this source is its minimal power consumption, optimized power consumption in idle […]
LED Driver Power Supply Circuit Using Dimmer Switch
In this post I have explained an effective and efficient high current compact LED Driver power supply using a dimmer switch gadget. In one of my other posts I discussed a high voltage transformerless power supply circuit that used a triac for controlling the capacitive output, however since the concept involved shorting the capacitive output […]
Making a Regulated 9V Battery Eliminator Circuit
The post presents a regulated 9V battery eliminator circuit which was built and investigated by Mr. Steven Chiverton, an avid reader of this blog and an experienced electronic hobbyist. I have explained more from him. 9 volt battery eliminator circuit tests: Circuits built 2x each circuit ive made a small modification to it buy adding […]
0 to 50V, 0 to 10amp Variable Dual Power Supply Circuit
In this post I have explained a simple yet very useful 0 to 50V dual power supply circuit which will enable a full 0 to maximum dual voltage +/- control of the input power supply DC. It also includes a wide range current control feature right from 0 to 10 amps. The idea was requested […]
