This 30V 1Amp Transformerless Power Supply Circuit works like small adapter for our electronic, as it takes normal high voltage electric and change it to low safe voltage to what our devices need. No large transformer is required because the circuit uses special components such as capacitors and diodes to perform the same function. Like […]

Simple Flip Flop Circuit
Think about small switches, they only do “ON” or “OFF”, but this Simple Flip Flop Circuit is same like that but for electronics. It stay in two state like 0 or 1, this small switch is very important it can remember stuff, keep data and help control what happen next like timing and by coordinating […]
LM317 IC Solar Charger Circuit with Auto Cut off
LM317 IC Solar Charger Circuit with Auto Cut off works like smart nanny for a battery, as it takes sunlight and charge battery but stop at right time. Also, inside it have one smart chip called LM317 which control charging and gives battery only needed power which is not too much. The best part is […]
Mains AC Transients Indicator Circuit
Think like anyone have one small device to check its home electricity going up and down; then this Mains AC Transients Indicator Circuit is same like that but only for sudden high voltage. These high voltage come from lightning and big machine turning ON or power change, also this circuit have one sensor who is […]
DC Voltage Doubler Circuit
DC Voltage Doubler Circuit is like small power booster, which takes normal battery power and make almost double. Also, it use smart parts like diodes and capacitors and they work like tiny switch and small electric bucket; sometimes many also use transistor or tiny chip to help. Imagine electric flow from battery like small stream, […]
Simple Regulated Adjustable Power Supply Circuit using IC 723
To begin with, this Simple Regulated Adjustable Power Supply Circuit using IC 723 show how to make one simple power supply circuit, which can change voltage up and down. We can use one chip call LM723 with some people say IC 723, this chip is good and it take power from plug and makes it […]
