This circuit is about a simple 7806 Based 6V 1A Regulated Power Supply Circuit which converts AC mains voltage into stable 6V DC output. Many small electronics projects need fixed 6V supply and this circuit gives clean and reliable output. Main part of this circuit is IC 7806, a simple linear DC voltage regulator IC […]
Automatic 12V Battery Charger Circuit with SCR Cutoff
This circuit is for Automatic 12V Battery Charger Circuit with SCR Cutoff, first it charges the battery and then it stops charging when the battery becomes full. Also, the circuit uses simple parts like transformer, diodes, SCR, resistor and capacitor and we can easily find these parts in market or online. So, this circuit protects […]
Overcurrent Protection Circuit using Transistor and FET
This circuit shows about FET overload current protection using transistor and MOSFET. If the load draws too much current or the output gets short-circuited then this Overcurrent Protection Circuit using Transistor and FET can help you. The main purpose of this circuit is to protect load from high current, like when current increases above limit […]
Transistor Based 12V Emergency Light Circuit
This project is for Transistor Based 12V Emergency Light Circuit system, which gives light when main power fails. The circuit uses transformer, bridge rectifier, transistor, relay, battery and few other components. When AC supply is present, battery charges and lamp stays OFF and when AC power goes OFF then battery gives supply and lamp turns […]
220V Emergency Light Circuit without Transformer
Like our previous tutorial on emergency light circuit, here is another post on 220V Emergency Light Circuit without Transformer. Today, power cut is common problem, so emergency light is very useful, as it gives light when mains supply is OFF. Usually, emergency light uses transformer but transformers are costly and bulky, therefore, this circuit is […]
Easy Emergency Light Circuit using Transistors
Power cut can come anytime, so our room becomes dark and feels very scary and bad. So, this small circuit gives light instantly, also there is no switch needed and no tension. Then light turns ON automatically and this happens because of simple and Easy Emergency Light Circuit using Transistors. Now, the circuit works like […]
