Imagine we play guitar but we want loud, fuzzy, buzzing sound which is not clear. A Simple Guitar Fuzz Circuit is like small monster in a box. It changes our normal sound and makes it fuzzy, noisy or roaring. Rock and blues players use this as it comes in small box with buttons we press […]
How to use an LED as a Light Detector Circuit
LEDs mostly make light but they can also sense light! Like a secret power when light hits an LED the right way it makes a tiny bit of electricity. This is called the photovoltaic effect like a tiny solar panel. In this post for How to use an LED as a Light Detector Circuit we […]
Simple Speaker Audio Output Transformer Circuit
Imagine our voice is strong but we whisper through a tiny straw to reach our far friend but it wont work. Same is in circuit for Simple Speaker Audio Output Transformer Circuit which works like a megaphone for sound signal. It takes strong signal from amplifier and changes it to fit the speaker so music […]
Simple Transistor Tester Circuit
Transistors are small switches. But how to check if they work or what type they are? This Simple Transistor Tester Circuit is like a transistor checker. It is an easy DIY project which uses few parts. It tells us if transistor is good or bad and also shows if its NPN or PNP like two […]
