Oscillator Circuits

A zapper circuit is a circuit that generates a specified frequency electrical current for therapeutic reasons, using a IC 555 integrated circuit. This circuit is often known as the Hulda Clark zapper version which was designed in the year 2003. Circuit Working: Parts List: Category Description Quantity Wattage Resistors 1k, 3.3k 2 each 1/4 watt […]

In this article a Morse code is a circuit that utilizes a IC 555 integrated circuit, it is an easy to make electrical circuit that may be used to practice transmitting morse code. Multiple configurations are possible for the 555, an IC that is highly adaptable. It is configured as an astable multivibrator in this […]

A basic circuit that simulates a ticking bomb is one that sounds like it might appear in a video game or motion picture. It is critical to realize that this circuit is only for amusement and does not provide any risks. Circuit Working: Parts List: Component Type Value Quantity Resistor 47k 1 Capacitors Electrolytic 10μF […]

The 555 timer chip is very common and easy to use. It is great for many projects. But to use it in certain circuits, you need to understand how it works at rest. There are two important parts to this: the upper threshold pin 6 and the lower threshold pin 2. IC 555 Pinouts Here […]

Visualize a gadget that makes sounds like a whistle, but you can control how high or low the pitch is with a knob. That is kind of what a voltage controlled oscillator VCO circuit does. It is an electronic device that creates a continuous signal often a square wave and uses a voltage to change […]

If you you need a super precise and steady beat for a song? A pierce oscillator is a musical instrument that can hit that exact note perfectly every time. It uses a special crystal, like a tuning fork to create a very stable electronic signal at just the right frequency. That is why it is […]
