220V Inverter Circuit using 2N3055 Transistors
This article show how to make a strong 220V Inverter Circuit using 2N3055 Transistors, which can change 12V battery like car battery into 220V electric for home. Also, it is easy to make and does not need many parts, and work very good. WARNING: But be very careful, homemade inverter can be dangerous always check […]
Audio Mixer Circuit using a Single Transistor
To begin with, this Audio Mixer Circuit using a Single Transistor is an small and easy circuit which mixes three sounds; it uses only one transistor which can mix two or three sounds into one. Also, it is good for beginners who want to learn about sound and electronics Circuit Working: Parts List: Components Values […]
Simple Lie Detector Circuit using Transistors
Have fun making this Simple Lie Detector Circuit using Transistors. Real lie detectors are very hard and complicated so this one is not perfect; but it is fun way to see how body react when its in stress. Also, this circuit works by detecting changes in sweat to check whether someone may be telling the […]
Simple Logic Probe Circuit using Transistors
This article for Simple Logic Probe Circuit using Transistors tell how to make one useful tool called voltage tester; also it uses two transistors for checking if some place in circuit have positive voltage. Further, when it find electricity it makes beep sound and small light turns ON. Here, people who want to learn electronics, […]
Class A Amplifier Circuit
This article talk about Class A amplifier which is good for small speaker or headphone, also amplifier make sound more loud. Further, this Class A Amplifier Circuit uses near 20 milliamp power so it good for low power thing and we can show in this post how to make it using Q1 and Q2 transistor […]
