In this post I have explained a circuit idea which can be used as a power monitor and control system for ensuring that only the specified amount of watts is allowed to enter into the allocated socket, as per the maximum calculated wattage of the appliances connected across those points. The idea was requested by […]

Electronic Load Controller (ELC) Circuit
In this post I have explained a simple electronic load controller or governor circuit which automatically regulates and controls the rotational speed of a hydro-electric generator system by adding or deducting an array of dummy loads. The procedure ensures a stabilized voltage and frequency output for the user. The idea was requested by Mr. Aponso […]
Load-Line Analysis in BJT Circuits
So far we have been studying BJT analysis dependent on the level of β over their corresponding operating points (Q-point). In this discussion we will check out how a given circuit conditions can help in determining the possible range of operating points or Q-points and in establishing the actual Q-point. What is Load Line Analysis […]
How Load Conducts in Half-Bridge Driver Circuits like IR2184 or IR2110
Many folks, especially beginners, they get fully confused when they try to use a half-bridge driver circuits using ICs like IR2184 or IR2110. They look at the datasheet diagram and start thinking, “Bro, how the load will conduct? The MOSFETs are switching one by one so how the current will pass through the load? Looks […]
Over Voltage Protection for Automotive Load Dump
In this post I have explained an over voltage cut-off protection circuit in the form of automotive dump load for protecting sensitive and sophisticated modern automotive electronics from transient DC electrical spikes emanating in vehicle electrical. Transient bus voltages are a significant risk factor to integrated circuits. The maximum breakdown voltage that an integrated circuit […]
Digital Weighing Scale Using Load Cell and Arduino
In this post I have explained about strain gauge based load cell. We will be exploring what Strain Gauge is, what Load Cell is, temperature effect on strain gauge, temperature compensation with Wheatstone bridge and Load cell amplifier HX711, and finally I have explained how to build an Arduino based weighing scale machine by implementing […]
