Power Supply Circuits

Regular power adapters give a fixed amount of power. This circuit is like a trick adapter using chips like the 7805 or 7812 normally for 5V or 12V along with other bits like resistors and potentiometers. By adding these extras, the circuit can twist and turn the voltage output to a wider range letting you […]

Imagine a super powered adjustable power adapter for your electronics projects. This circuit uses a special chip LM350 that acts like a strong and reliable power source. It can crank out up to 3 amps of juice and adjust the voltage anywhere from 1.25V to 25V. This makes it perfect for powering all sorts of […]

This DC to DC adjustable converter circuit with the TL497A chip is like a little helper that can adjust the voltage of your power source. It can take a lower voltage and give you a higher voltage just like a mini power adapter. The cool thing is, this circuit can be adjusted configured to work […]

This 3V to 24V variable power supply circuit is like a swiss army knife for powering your electronics. It is one power supply that can act like many. You can twist a knob or adjust a setting to change the voltage output anywhere from 3V all the way up to 24V. This makes it perfect […]

This 3V to 9V DC boost converter circuit is like a superhero for your batteries. It can take a weak 3V battery, like a dead one in your remote, and jumpstart it to a powerful 9V which is what many devices need to run. This is perfect for situations where you only have low voltage […]

A Solid State Relay SSR circuit is like an electronic ON/OFF switch, but way cooler. Unlike regular switches with clicky parts, this one uses special electronics transistors or triacs to turn things on and off. This makes it super reliable, quiet and lasts a long time, perfect for all sorts of electronic projects. Circuit Working: […]
