Simple Triac Triggering Circuits Explained
In this post we learn the fundamental methods of triggering a triac, and also discuss the right way to connect the terminals of a triac. Triacs are solid-state bidirectional thyristors […]
Simple 10 Watt Amplifier Circuits using Transistors
The post comprehensively explains 3 easy to build 10 watt power amplifier circuits, which can be built using discrete parts, such as resistors, transistors, and MOSFETs. The MOSFETs used in […]
IC 4047 Astable, Monostable Circuits
In an IC 4047 astable oscillator circuit, the output of the IC continuously generates a switching ON/OFF signal. Since the output is never in a stable state and constantly switches […]
9 Simple Sine Wave Generator Circuits Explored
A sine wave generator is actually a sine wave oscillator circuit which generates an exponentially rising and falling sinusoidal waveform. The 9 simple sine wave generator circuits presented in the […]
LED Star Circuit
This circuit can be used like a tree ornament, however the LED star circuit explained here has a variation; it’s completely electronic and it provides the impression of an exploding […]
