In this post I have explained a circuit which can be used for monitoring or controlling AC 220V load current by sensing the load current through a contactless current transformer. Figure 1 below depicts a circuit diagram designed for a non contact load current sensing through a current transformer, which seemed to work well. It is […]

Listen to Wildlife and Insects with this Circuit
In this post I have explained a simple circuit idea which can be used for listening to the amplified sounds of insects and bugs in gardens, trees, or any deserted, quite backyards. Listening to the noises of outdoor wildlife may be a genuine auditory delight as well as a signal of impending danger. When it […]
Different Types of UPS systems – Explained
In this post I am going to explain different types of uninterruptible power supply (UPS) that are available in the market and how they are classified according to the consumer’s requirement. We will also explore the different types of UPS’s block diagram to understand their technical difference between them. UPS systems are a type of […]
Clipper and Clamper Circuits Explained
In this post I am going to explain clipper and clamper circuits. The clipper and clamper are called wave shaping circuits because they convert the incoming signal wave to another kind of useful wave. They are used widely in power supplies, filter circuits, RF transmitters / receivers, voltage suppressors, audio amplifiers and the list goes […]
Gel Cell Battery Charger Circuit [Constant Current, Constant Voltage]
In this post I have explained what are gel cell batteries and also learn how to build a specialized charger for charging a gel cell battery, with full calculations. The proposed circuit works in two modes: it starts charging a discharged gel cell battery with constant current, until the full charge voltage is reached across […]
Simple E-Bike Circuit [Electric Bike]
This E-bike or electric bike circuit I have explained below can be used as the control circuit for constructing a homemade E-bike, with the help of a permanent magnet motor DC (PMDC motor), and a Li-Ion battery. An electric bike is basically a bicycle powered through a motor and a battery, which does not require […]
