Voltage regulators is very important in power supply as they keep voltage steady and even if input voltage changes or load changes. This circuit give steady 12V output with max 3A current and if current need more than 3A then it still works good for regulation. High Current 12V Voltage Regulator Circuit using Transistor give […]

Xenon Tube Stroboscope Circuit
Xenon Tube Stroboscope Circuit show how to make flashing light using special xenon tube stroboscope, as this circuit uses only few parts and can plug in normal 220V power socket to make light flash very bright! WARNING: This circuit uses high voltage, which can be dangerous, so we should seek help from an expert electrician. […]
Simple Room Ionizer Circuit
In this Simple Room Ionizer Circuit, a machine called a room ionizer helps clean the air in a room and it also creates small electric particles called ions. Furthermore, these ions catch smoke, dust and bad things in air and ionizer use special electric way to make these ions. Like when we press one side […]
220V Over Under Voltage Cut Off Circuit using Transistors
This 220V Over Under Voltage Cut Off Circuit using Transistors help to protect electric things from too high or too low voltage, it also uses two transistors and some easy parts. First, when voltage goes too much high or too much low then circuit cuts the power, also it is good for home use and […]
