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 […]
Power Amplifier Circuit using IC 741 and MOSFET
In this post we study a power amplifier design configured using an ordinary IC 741 and a couple of MOSFETs. An operational amplifier’s output power such as from an IC 741 can be typically enhanced when a complementary emitter follower transistor is coupled at its output. The same could also generally be accomplished using a […]
Homemade 2000 VA Power Inverter Circuit
Making a power inverter circuit rated above 2000 VA is always difficult, mainly because of the involved transformer dimension which becomes quite huge, unmanageable and difficult to configure correctly. Introduction Power inverters in the range of KVA, requires huge current transferring capabilities for implementing the required operations as per the desired specs of the unit. Transformer being the main power […]
Automatic Vehicle Headlight Dipper/Dimmer Circuit
The circuit described here can be built and used in your vehicle for an automatic dipping and dimming operation of the vehicle headlamps, in response to the intense lights coming from an opposite vehicle headlamps. What’s a Dimmer/Dipper in Automobiles An automobile headlight dimmer/dipper is a circuit which automatically switches the headlight intensities of vehicles arriving from […]
How to Use LM317 for Making a Variable Power Supply Circuit
In this post I will elaborately explain how to build a simple LM317 based adjustable power supply circuit using minimum number of external components. As the name suggests a variable power supply circuit provides the user with a range of linearly varying output voltages through a manually controlled potentiometer rotation. A LM317 is a versatile […]
