In this post I have explained about a simple mechanism, and a circuit which will enable a patient’s IV drip bottle system to sound an alarm whenever it gets almost empty, and needs a replacement. The warning circuit will help doctors and the concerned employees to concentrate on other important matters while the drip systems […]

What is Constant Current Source – Facts Explained
In this post I will try to analyze what is constant current source and how it affects a load, or how it may be used with a load correctly for achieving the most efficient results. The following discussion between me and Mr. Girish will clearly explain what is CC or how constant current operates. How […]
How to Repair a Switch-Mode-Power-Supply (SMPS)
In this post we try to diagnose a burnt SMPS circuit and try to troubleshoot and repair the circuit. The shown unit is a cheap readymade Chinese make SMPS circuit. This article is written as per the request made by Mr. Kesava. My SMPS got Burnt The below attachment is 12v 1.3 amps SMPS for […]
3 Best Transformerless Inverter Circuits
As the name suggests, an inverter circuit that converts a DC input into AC without depending on an inductor or a transformer is called a transformerless inverter. Since an inductor based transformer is not employed, the input DC is normally equal to the peak value of the AC generated at the output of the inverter. […]
SMS Based Water Supply Alert System
In this post I will show how to construct a circuit which will notify the user via SMS if the water supply to you area / home is initiated. It can show the time when the water is begin to supply and ended, average water flow speed in liter per minute and total water delivered […]
Incubator Using Arduino with Automatic Temperature and Humidity control
In this post I will show how to construct an incubator using Arduino which can self-regulate its temperature and humidity. This project was suggested by Mr. Imran yousaf who is an avid reader of this website. Introduction This project was designed as per the suggestions from Mr. Imran, but some additional modification is done to […]
