This project is designed to be used with a 12v battery. This voltage is boosted to about 220-250V AC. I am planning to create a capacitor charger out of this. An other goal of the project was to build ...

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...

Here is a simple 12 volts DC to AC inverter circuit. This 120V AC power source is built with a simple 120V:24V or 110V:24V center-tapped control transformer and four additional component. This circuit ...

When you’re testing or debugging some mains-powered gear, plugging it directly into the outlet can often be an exciting ...
