Today, when we want to make a device that uses a 12 volt voltage source, we can not possibly carry a large 12 volt PSA's everywhere. Now, to complement the tools that we make it, we must also make an appropriate voltage source with the tools we create.
Here, I will provide a circuit that can be used for devices that operate at a voltage 12 volts.
Many Power Supply circuits is also available on the Internet for free but may be making the circuit that requires a high cost, such as power supply circuit using the LM388, LM388 price per one unit rather expensive. I give this circuit requires only a low cost.
This is the its PCB layout.
Transistors can be replaced with another type with the desired current rating. For the type 2N3055 transistor is rated for currents up to 15A.

There are Power Supply 12V Selection :
