This project for Simple Machine Gun Sound Generator Circuit using IC 555 which makes circuit like machine gun sound, short and fast bursts. Here, 555 chip give quick electric pulses and controls the sound timing and this pulses turn into sound and make “rat-a-tat-tat” noise. If want loud sound? its easy! just add amplifier and […]

Simple Morse Key Circuit using IC 555
This article show how to make a Simple Morse Key Circuit using IC 555, which is an easy circuit and is good for Morse code practice. Also, IC 555 can work in many ways, in this project it work as astable multivibrator which means it make signal by itself and there is no need for […]
Wailing Siren Circuit using IC 555
A Wailing Siren Circuit using IC 555 is simple to make sound like real siren, going up and down in pitch, also the sound come from 555 IC making pulses at certain speed (frequency). Circuit Working: Parts List: Components Values Quantity Resistors 390Ω, 1k, 220k, 100k, 33k, 22k 1/4 watt 1 each Capacitors Ceramic 10nF […]
Stun Gun Circuit using IC 555
Stun Gun Circuit using IC 555 is simple electric device which make high voltage for non-lethal self defense. Remember, before making it we must know the danger and law rules to follow. Circuit Working: Parts List: Components Values Quantity Resistors 33k, 1k 1/4 watt 1 each Capacitors Ceramic 10nF, 100nF 1 each PPC 10nF 400V […]
Motor PWM Speed Controller Circuit using IC 555
Do we need to adjust the voltage control knob to change the motor speed? then this smart Motor PWM Speed Controller Circuit using IC 555 to control DC motor speed. Also, it turn motor power ON and OFF very fast so motor gets average voltage and its speed changes; like dimmer switch but for motor. […]
Simple Light Dependent Screamer Circuit
Fun small and Simple Light Dependent Screamer Circuit make sound change with light; it uses LDR like a special resistor which changes with light. Furthermore, as the light intensity increases, the sound becomes louder or higher in pitch, therefore, we call this circuit a Light-Dependent Screamer. Circuit Working: Parts List: Components Values Quantity Resistor 1k […]
