This project is a variation on those using linear voltage regulator chips to power low-voltage experiments wherein it uses a low dropout regulator to allow lower input voltages and a fine adjustment system.
The small-circuit project illustrates a switch mode power supply (SMPS) that boosts low voltage to the high voltage require to drive nixie tubes while being operated on batteries or low voltage wall-warts.
This project aims to build a DC power supply that will be controlled by a microcontroller and features an LCD display and the use of Linux computer to send commands via RS232 interface.
The goal of the project is to create a micro PSU to provide power on a breadboard with 5 Volts supply as the whole circuit can be connected to 9V battery, 12V or any other DC power source from 8 to 18V.
