Do anyone want to play drums but do not have full drum kit? This Electronic Drums Simulator Circuit work like small electronic drum. It uses smart parts to make drum sound like kick and snare. Sound come from electronics and not from real drum. Can make sound using things like relaxation oscillator like build and […]
PWM Motor Speed Control Circuit using Two Transistors
Resistors can help in some ways but they are not good for smoothly changing motor speed. That is why a smart PWM Motor Speed Control Circuit using Two Transistors is used. It works like a dimmer switch for the motor. We turn a knob like a potentiometer to change how much power the transistors get. […]
Microphone Preamplifier Circuit using Two Transistors
Imagine our voice is a tiny whisper going into a microphone. This Microphone Preamplifier Circuit using Two Transistors works like a small megaphone. It makes the whisper louder so the main amplifier can clearly boost our voice. Circuit Working: Parts List: Component Type Description Quantity Resistors(All resistors are 1/4 watt unless specified) 100k 1 120k […]
“Hee Haw” Siren Circuit
The “Hee Haw” Siren Circuit is a fun sound project that makes a high and low noise like “Hee Haw” instead of one long sound. It is made using simple electronic parts like resistors, capacitors and transistors or sometimes ICs. The pitch of the sound goes up and down again and again. We can find […]
How to Convert a Speaker into a MIC Circuit
This article for How to Convert a Speaker into a MIC Circuit shows how to turn a speaker into a microphone. It uses the speaker to catch sound. The sound turns into a weak signal. A transistor circuit makes the signal stronger. The mic wont be very clear but it is a fun way to […]
Fog Horn Circuit
Ever wondered how fog horns make that deep, spooky sound? This Fog Horn Circuit is a small sound-making device. It uses electronics to make the low, rising and falling fog horn noise. People use these circuits for fun projects or to learn about electronics. Circuit Working: Parts List: Component Value/Type Quantity Resistors( All resistors are […]
