In this post I have explained s few simple DC to DC buck-boost converter circuits which can be used for either stepping up the input DC voltage or stepping down the input DC voltage to specific output DC voltage levels. Since a buck-boost converter allows the input voltage to be either stepped up or stepped […]

Capacitor Inductor Calculations
Inductors can be imagined as the opposite of capacitors. The main difference between a capacitor and an inductor is that a capacitor carries a protective dielectric between its plates, which inhibits the conduction of current across its terminals. Here it acts like an open circuit. On the other hand the inductance of an inductor is […]
Free 200 Volts Just Above your Head
Lightning in skies is the phenomenon which proves beyond doubt that free electrical energy could be there in abundant quantities all around us. Warning: The concept I have explained in this article has not been verified by the author. Readers are advised to read and proceed at their own discretion. Power of Thunder Lightening A […]
Ion Detector Circuit [Static Discharge Detector]
The following post discusses a simple ion detector circuit which can be used for detecting positive and negative ions generated by high voltage circuits. This device can be also used for detecting static discharges in the atmosphere. Static discharge is normally emitted by high voltage sources such as sparks, arcing etc. It may be also […]
How to Understand and Use IC 4093 NAND Gates, PinOuts
In this article I have explained how to use NAND Gates from the IV 4093 or any other similar IC consisting of NAND gates. About IC 4093 The IC 4093 may not have complicated specifications and attributes yet it proposes many useful utilities. It consists of some fundamental blocks which can be configured according to […]
DC Lamp Dimmer Circuit using IC 555
In this post I have explained how to use the control pin#5 of the IC 555 to build a simple PWM controlled DC light dimmer circuit. The proposed DC lamp dimmer can be used for controlling the light intensity of any DC lamp having an operating voltage anywhere between 6 V and 12 V. The […]
