12V Battery Charger Circuits [using LM317, LM338, L200, Transistors]
In this article I will be discussing a list of simple 12V battery charger circuits which are very easy and cheap by its design yet extremely accurate with its output voltage and current specs. All the designs presented here are current controlled meaning their outputs will never go beyond a predetermined fixed current level. UPDATE: […]
12 Simple IC 4093 Circuits and Projects Explained
The 4093 is a 14-pin package containing four positive-logic, 2-input NAND Schmitt trigger gates as shown in the following figure. It is possible to operate the four NAND gates separately or collectively. The individual logic gates of the IC 4093 works in the following manner. As you can see each gate has two inputs (A […]
12 Basic Digital Logic Circuits Explored
In the following paragraphs I will try to explain the most basic foundations of digital electronic circuits: namely logic gates and logic flip-flops. Whether it is a complex and larger digital circuits, or as simple as a BCD counter, for example the 7490, or a large-scale integration (LSI) microprocessor chip, eventually all of these comprise […]
Audio Clipper and Compressor Circuits Explained
In this article I have explained using circuit diagrams how a clipper and a compressor circuits work to processes an input audio signal as per the required output signal. What is an Audio Clipper An audio clipper circuit is basically used to alter or restrict the amplitude (volume) of an audio signal. There are mostly […]
10 Simple IC 555 Monostable Circuits Explored
In this post I have explained how IC 555 can be used for making 10 different types of monostable multivibrator circuits, such as one-shot type, debounce preventor, retriggerable type, touch switch monostable circuit and many more. A monotsable multivibrator circuit is a configuration in which, a short momentary pulse at the input of the circuit […]
