Single Transistor Radio Receiver Circuit
This is probably the simplest radio receiver circuit that one could ever imagine of making. The circuit is so simple that it could be finished assembling within a few minutes and you are already listening your favorite programs over it. Introduction What are the fundamental criteria associated with radio reception? An antenna stage, a band […]
Simplest Piezo Driver Circuit Explained
In the previous post I explained a piezo transducer element and learned how to use it with electronic circuits. In this article we will see how a piezo tranducer can be driven or operated using a simple circuit. As discussed earlier a piezo transducer basically requires a frequency to vibrate and reproduce the required sound. […]

No complex wiring, no costly MOSFETS and no cumbersome heatsinks, yet a powerful 200+200 watt stereo amplifier circuit, which can be built within hours using just a couple ICs, right in your home. Yes we are discussing the state-of-the-art thick film hybrid IC STK4050II, by SANYO.The IC is specifically designed for amplifying music at an […]
Adding a Soft Start to Water Pump Motors – Reducing Relay Burning Problems
In this post I have explained a few innovating and simple soft start circuit examples which may be implemented with heavy duty motors so that they are able to initiate with a soft start or a slow sluggish start instead of a sudden, bumpy start Why Soft Start is Crucial for Heavy Motors When heavy […]
3-Step Automatic Fast Battery Charger/Controller Circuit
Generally it is noticed that while charging batteries people hardly pay any special attention toward the procedures. For them charging a battery is simply connecting any DC supply with matching voltage with the battery terminals. A fast battery charger circuit charges a battery with enhanced speed so that it is charged in less time than the specified period. […]
