An LED based LightStim is a device used for rejuvenating facial skin by stimulating cell growth. Normally, RED LED is used in these devices since red light have been found to be working the best for improving skin health, by eliminating facial wrinkles. Blue LED light have proved more effective against harmful bacteria responsible for […]

Optocouplers – Working, Characteristics, Interfacing, Application Circuits
OPTOCOUPLERS OR OPTOISOLATORS are devices that enable efficient transmission of DC signal and other data across two circuit stages, and also simultaneously maintain an excellent level of electrical isolation between them. Optocouplers become specifically useful where an electrical signal is required to be sent across two circuit stages, but with an extreme degree of electrical […]
Rotating LED Chakra Circuit for God Idols
LED Chakra is an ornamental lighting system which depicts or imitates a rotating wheel like appearance, by means of sequentially shifting Illuminated LED arrays. Indian subcontinent is a land of festivals and celebrations which mostly start from the month of August and continues until the New Year. All these festivals have one fundamental thing in […]
SCR Applications Circuits
In this article I have explained many interesting SCR application circuits and also learn the main features and properties of an SCR also called a thyristor device. What’s an SCR or Thyristor SCR is the acronym of Silicon Controlled Rectifier, as the name suggests it’s a kind of diode or a rectifying agent whose conduction […]
Electronic Touch Organ Circuit
An electronic touch organ is an intriguing musical device which produces very pleasant musical notes in response to finger touches on special touch sensitive electronic pads or buttons. Modern day organs are, however, very costly which usually places these outside the reach of the majority of folks. Low cost options types lack performance, and are […]
Schottky Diodes – Working, Characteristics, Application
Schottky barrier diodes are semiconductor diodes designed with minimal forward voltage and fast switching speeds which may be as low as 10 ns. These are manufactured in current ranges of 500 mA to 5 amps and up to 40 V. Due to these features they become specifically suitable in low voltage, high frequency applications such […]
