Overview

We have converted a Normal old computer power supply into a 3V, 5V, and 12V power supply which takes 220 volts as input and gives DC voltage according to our need, and displays the required voltage flowing through the banana switch which is attached to the display.

We can run all kinds of motors, bulbs, LEDs, DC Fans, too current Arduino, it can also give current to our drone by simply connecting the wire to drone motors. It is very easy to moveable take less cost than a normal computer supply which we purchase from the market. It is 20 times less than in price which is available in the market.

Power supply

Power Supply Circuit

The most common source of power supply these days is the AC mains, because it is more efficient and economical to generate and transmit AC power. However, DC voltage/current are required for the satisfactory operation of a wide variety of electronics equipment

Components we use in project:

Banana switch

Potential meter

12 V DC Digital LED Display

Resistance

Switching button

Working of components

Banana switch:

Banana Socket for Power Supply Round Female Socket Plug Connector Banana Socket for Power Supply, 2 pieces, Round Female Type Socket

Plug Connector

Potential meter

A potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element.

12 V DC Digital LED Display

Our 12 volt monitors are energy efficient and can be connected directly to a 12V circuit. The monitors are suitable for continuous use and have various mounting options.

Resistance

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses

Switching button

A push switch (button) is a momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated
