With temperature, if there is one characteristic physical quantity of the past or future weather, it is certainly atmospheric pressure. The variations of this quantity are particularly interesting for weather forecasting: a decrease in pressure invariably heralds the arrival of rain, while a significant increase is a certain sign of improvement or persistent good weather. […]

Super Capacitor Charger Theory and Working
In this post I have explained a super capacitor charger circuit for charging super capacitors which converts a 12V car battery voltage to an elevated 16V for charging a bank of super capacitors. The idea was requested by Miariver. Super Capacitor for Peak Power Compensation First thanks for keep publishing this blog is very helpful, […]
Analyzing Class B and Class AB Amplifier Models
Both the majority of class B or AB power amplifiers currently encountered in HI-Fi amplifiers are presented in the form of integrated circuits specifically designed for this purpose. It is interesting for technicians to know how this type of amplifier works, if only out of intellectual curiosity. The provided model allows the study of several […]
Convert any Existing AC Lamp into Timer Controlled Lamp
The proposed push button timer circuit module can be directly integrated with any existing switch contacts of a lamp and enable the lamp to be converted into a timer controlled lamp. A common problem arises whenever one wants to replace a mains AC lamp controlled by a switch with a timer or a time switch. […]
LM567 Tone Decoder IC Features, Datasheet and Applications
In this post I have explained the main specifications, datasheet and working principle of the IC LM567, which is a precise phase-locked loop with synchronous AM lock detection and power output device. In simpler terms the IC LM567 IC is a tone decoder chip which is designed basically for recognizing a specified frequency band, and […]
32 watt Amplifier Circuit using TDA2050
In this post I have explained how to build a simple yet powerful 32 watt amplifier circuit using a single chip TDA2050 and with a handful of resistors and capacitors. By: Dhrubajyoti Biswas Working Principle of TDA2050V This article will detail building a stereo amplifier along with an output for a headphone jack. It is […]
