A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload sensor and also as an under voltage detector. In both the cases the circuit trips the relay for protecting the output under the above conditions. […]

Calculate Battery, Transformer, MOSFET in Inverter
In this post I have explained how to correctly calculate inverter parameters with associated stages such as battery and transformer, by calculating the matching the parameters correctly. Introduction Making an inverter all by yourself can be definitely lot of fun. However if the results are not satisfactory can completely spoil the whole purpose of the […]
20 Watt Fluorescent Tube Light Circuit with 12V Battery Operation
This simple 20 watt home tube light circuit will work with any 12V battery and uses very few components yet is able to produce a reasonable amount of white light. The components used are very common and can be easily procured from the local electronic retailer. The idea is simple, the secondary winding of Tr1 […]
Potato Battery Circuit – Electricity from Vegetables and Fruits
In this article I have explained how vegetables can be used for making an organic battery, through an example of a practical potato battery experiment. Alessandro Volta was probably the first man to devise the method and idea of generating electricity from electrolytic solutions. According to his concept, two dissimilar metals when brought in contact […]
Flashing LED Battery Low Indicator Circuit
In this post I have explained a simple low/normal battery voltage status indicator circuit through a flashing and a constant LED, where the flashing LED indicates a normal status while the solid indicator warns against a low battery condition. The idea was requested by Mr.Alf. Technical Specifications Hi, I found and built your “Low Battery […]
Battery Current Indicator Circuit – Current Triggered Charging Cut off
In this post I have explained about a simple battery current sensor with indicator circuit which detects the amount of current consumed by the battery while charging. The presented designs also have an auto cut off when the battery stops consuming current at its full charge level.. Why Current Drops as Battery gets Charged We […]
