Neon Tube Flasher Circuit
Neon light look very nice but it needs much electricity to work; this Neon Tube Flasher Circuit show how to make special circuit to turn ON and OFF neon light using small battery with low voltage DC. WARNING: Making high voltage circuit can be dangerous, so do this only when adults are watching. What is […]
Simple FET Two Lamp Flasher Circuit
To begin with, this simple FET Two Lamp Flasher Circuit connect same like simple astable multivibrator and also they make easy circuit for two lamps flashing one after other. What is a FET Lamp Flasher Circuit: The circuit using FETs mostly used for flashing lights or bulbs and it also uses some other parts but […]
Simple Adjustable Oscillator Circuit using Two Transistors
To begin with, this article for Simple Adjustable Oscillator Circuit using Two Transistors show how to make small sound circuit using only two transistors! Hence, when we turn the knob the sound goes high like beep or low like growl, also we can use four AA battery or small wall power to run this circuit. […]
Latch Circuit using Transistors
This article for Latch Circuit using Transistors talk about how to make a small electric switch and this switch stay ON even after signal goes OFF. Also, it does not cost much and is easy to make, as it uses transistor and some other parts. If someone gives small signal to turn it ON it […]
Set Reset Latch Circuit using Transistors
This Set Reset Latch Circuit using Transistors tell us how to make an easy electric switch with two ON/OFF using two transistors. Also, many devices are used in special switching circuits like an SR latch to keep data even when the power turns OFF and then ON again. Furthermore, this type of circuit mostly uses […]
