If you have an old computer power supply, then you can make a power supply out of it for various electrical needs. Let's see how the Master made such a power source.
Tools and materials:
- PC power supply;
-Light-emitting diode;
- Terminals;
-Clips;
-Wire;
-Socket car;
-Soldering iron;
-Resistor;
-Screwdriver;
-Hair dryer;
-Heat-shrink tubing;
- Pliers;
-Knife;
- Crimping pliers;
-Rubber ring;
-Drill;
Step One: PSU Disassembly
Parses the power supply. charges a fee. Cuts off regular connectors. The length of the wires should remain 15-20 centimeters.
Step two: wires
The next step is to determine which wires have voltage. The power supply unit of the master had the following wiring:
Red = + 5V
Orange = + 3.3 V
Yellow = + 12V
White = + 12V
Blue = -12 V
Black = GND
Thin Orange = +3.3
Slim red = +5 V
Green = went to the on button.
Gray = LED connected
Step Three: Installation
Further, the master connects the wires at par, and installs terminals at the ends. A green wire connects to the ground. Thin mixes with orange, red with red. Between red + 5V and GND, a 10 ohm 10W resistor is soldered. Mounts a car outlet. White wire to plus, black to minus. An LED solders to the gray wire through the resistor. The second leg to the ground. All ends are insulated with a heat shrink tube.
A series of holes are drilled in the housing. Sets the terminals and LED. Assembles the body.
The power supply is ready.
