1 W mini audio amplifier circuit
In this circuit requires only three components , namely IC TDA7052 , and 2 capacitor electrolyte. Actually , only with IC we are able to run this amplifier , but the sound less than the maximum. This amplifier circuit requires a minimum voltage of 3 volts and 15 volts maximum. Was 1 Watt power output with 4 Ohm impedance. See this circuit below :

| Just IC and 3 components we can make the circuit above. |

Mini and simple power amplifier circuits
What is the meaning of the picture above? The above picture is a miniature audio amplifier and very simple. Here I will give an audio amplifier schematic is very simple which only requires a few components only, can be seen under this scheme.
See from above scheme may occur to you, certainly cheap enough to make this amplifier and quite easy to make. The above simple audio amplifier circuit using an IC as the main amplifier and accompanied by other components. IC used is S1513, which requires a supply voltage ranging from 1.5 volts to 6 volts. And only 0.1 W output power with 4 ohm impedance. For a list components can be seen below.
Part list
C1 = 100nF
C2 = 100uF
C2 = 100uF
C3 = 3n3F
C4 = 1uF
C5 = 1uF
U1 = S1513
C5 = 1uF
U1 = S1513

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 :
