Low Noise Adjustable Linear Double Output AC-DC Power Supply
Every engineer needs at least one bench power supply in his house. I agree one can get the power supply directly from the store. How else?
How to build a professional 30V 4A adjustable bench supply using the ZK-4KX Buck-Boost Converter and a old laptop power brick.
A non microcontroller project, A battery charger and overvoltage protector. Can be used as universal battery charger for lithium/ lead acid.
A tiny DC to DC buck converter board is useful for many applications, especially if it could deliver currents up to 3A.
Taking a safe side, using low DC voltage in high power mode we can design a suitable hot plate for our SMT projects.
How to build an adjustable switching power supply using LM2576 [buck converter, CC-CV].
Make your own DC-DC Boost Converter to step up DC voltage
A small but powerful inverter circuit can power up your small devices. A Inverter with square wave Ac on output.
This power bank allows you to charge your mobile phones anywhere at any time when you do not have access to the ordinary charger.
This may be the lifesaver hack, the flex, with a night lamp and a hub of USB peltiers. Keep one with you, always.
Some projects need to work with AC main supply. I don't like to work with seperate boxes such as device and AC adapter.
