To begin with, 3V to 24V Variable Power Supply Circuit is like a Swiss knife, where one supply does many things; just turn knob to change voltage from 3V to 24V. Furthermore, this circuit is good for projects needing different voltage and hence, there is no need of many adapters, we just need to use […]

Simple 3V to 9V DC Boost Converter Circuit
This Simple 3V to 9V DC Boost Converter Circuit is like a hero for battery. If battery is only 3V like from old remote then this circuit makes it strong by giving it 9V as many device need 9V to work good. So if we only have small battery with low power but still want […]
Simple Cell Phone Charger Circuit using 1.5V Battery
This Simple Cell Phone Charger Circuit using 1.5V Battery is one special charger we can take anywhere but there is no need to plug; we can charge phone anytime. It also uses a standard AA or AAA battery like the one used in TV remotes, inside, it includes a circuit that boosts the weak battery […]
Simple Solid State Relay (SSR) Circuit
Simple Solid State Relay (SSR) circuit is like ON/OFF switch but with more better and modern; not like normal switch with moving parts but this one uses special electronics parts like transistor or triac for turning ON or OFF. Also, it works quietly with no noise and last a long time, it is very good […]
Simple Led Driver Circuit using IC LT1932
This Simple Led Driver Circuit using IC LT1932 chip works like special power for LED lights. LEDs do not like too much or too little power so this circuit gives just a right amount and then LED shine good and live long. Also, LT1932 chip work like traffic police it controls power flow nice and […]
1.5V to 5V Voltage Converter Circuit using IC MAX756
This 1.5V to 5V Voltage Converter using IC MAX756 works like small power booster for battery, as it takes low 1.5V battery like AA battery and makes it higher like 5V. Moreover, this help for running small electronic things that need 5V for working good; also the MAX756 chip is like small hero it help […]
