7812 voltage stabilizer
To obtain a pure DC voltage, then we must consider the regulation voltages and currents that we change from AC to DC current. For that we need some settings that can support our own making and its components were easy to get in the electronics market.This is series Power Supply that can be used on trafo 5 Ampere up to 10 Amperes.
If you want to use a larger transformer than 5 Amperes transistor 2N3055 is suggested that the double for the exit of the collector current is larger and in accordance with the current out of the transformer. How pemasanganya enough in the series on all sides of the pin.

78XX and 79XX stabilizer circuit with mini PCB design
Here I present the stabilizer circuit of the IC 78XX and 79XX commonly used for voltage stabilization with a mini PCB design , and practical. In the picture above is looking from top the PCB, with a width of 2 cm and 5 cm height. For input voltage can be directly through the AC because ive put it four rectifier diodes are then forwarded to the Elco and IC , that has a stable output in accordance with IC series. What if the IC series 7805 and 7905 , the output voltage of 5 Volts. If the series IC 7812 and 7912 then the output voltage of 12 volts , and so on. See circuit schematic below :
Part List :D1,D2,D3,D4 = 1N4007C1,C2 = 1000 uF/50VC3,C4 = 470 uF/50V
IC1 = 78xx series
IC2 = 79xx series
And this is PCB design look from bottom :
