Solar LED Lantern Circuit
Solar LED Lantern Circuit is small design using sun power to give light with LED, as it have solar panel through which the battery charges again to LED lights and some small parts like diode, resistor and transistor. Circuit Working: Parts List: Components Values Quantity Resistors 15Ω 1/2W 1 1.5Ω 1/2W 1 1k 1/4W 2 […]
220V Lamp Flasher Circuit using IC 555
This 220V Lamp Flasher Circuit using IC 555 uses one special chip IC 555 to make normal bulb blink like party light, also the chip make ON/OFF signal. Furthermore, this signal connects to transistor or triac which work like switch for bulb power and when power goes ON and OFF fast then bulb start blinking […]
Simple Backup Light Circuit
Think our lights are as a safety friend, this Simple Backup Light Circuit is like a good helper for our lamps, as it have two or more lights and smart system. If one light stop working the other light turn ON by itself and there is no need to stay in dark, it is very […]
Transistor 2N3055 Circuit with 1.5 Million High Gain
Transistor 2N3055 Circuit with 1.5 Million High Gain is like normal volume knob it can make sound more but not too much and if we want very loud like 1.5 million we need to trick it little bit. One way uses two transistors together like a double volume knob. People also call this arrangement a […]
Adjustable Power Supply Circuit using IC TDA2030
This Adjustable Power Supply Circuit using IC TDA2030 can change the voltage it uses small trick which is little bit surprising; because the chip TDA2030 is normally for making speaker sound loud and can also work like voltage controller. With smart circuit design it gives steady DC voltage and we can change output which is […]
