6 12 Volt Adjustable Power Supply Circuit

Power Supply has an adjustable output with a range of 6-12 VDC. The part that serves as a power regulator is Q1 TIP31. Then the controller output voltage is a voltage divider composed of R3, R4, VR1 and R2 provide bias to the base of Q2 to Q1 mengentrol power regulator. In a series of power supply is mounted 5.1 V zener diode which serves to make the minimum limit the output voltage with Q2.

12 Volt DC Power Suplly Adaptor
This series of images you can apply to make an adapter or power suplly with the output voltage (V DC output 12V). Power supply in the only protected by a capacitor as a safety if the power supply is connected to the load on the circuit.

So I recommend using 35V capacitor with a minimum specification. The security of power supply to power the more we can menggunakkan transistor TIP, but I have not discussed it. To the diode bridge can be compiled from the 4 then you solder the diode bridge rectifier into one or you can buy a bridge rectifier so that the comb-shaped (sideways) or the box. At least I would suggest using a diode bridge 1 Ampere, in a series of adapters, the bigger the better course of ampere diode current in the circuit. Diodes like toll roads, and current as a car passing by. The larger and the width of the existing highway, the faster the flow of runs and through the circuit.
For the circuit power supply 5 V, you can change the volt regulator on the type 7805 and 7905. This application applies equally in this series. For variations such as fuse or circuit switch on / off you can try it yourself.

Volt meters ampere meter with PIC
Volt meters & ampere meter with PIC can be used to measure voltage and current simultaneously. The series of volt meters & ampere meter with PIC16F876A PIC is used as a data processor voltage and current are measured.
This circuit uses the viewer in the form of 16 × 2 LCD used for the data menmpilkan voltage and current measurements. In the article volt meter and ampere meter with PIC are discussed kerannya limited to devices only. More detail can be seen from the image sequence volt meter and ampere meter with PIC below.

Stereo 9 Volt power amplifier circuit
Here I will explain about the necessary voltage and power amplifier output. The voltage should have at least approximately 9Volt 30Volt voltage and maximum voltage on the DC current. For maximum output of 2 X 2Watt with impedance 8-16 ohm. Because this amplifier circuit using ic and ic is used have the equation, so that if used different ic, then the required output voltage and also differ depending ic respectively.

Part List :

R1 = 1M
R2 = 1M
R3 = 1K
R4 = 1K
R5 = 100K
R6 = 100K
R7 = 1R

12 volt fluorescent lamp and transformer equipped
Valid schematic circuit diagrams of fluorescent lamps with a voltage source using 12 volt battery. This circuit 12 volt fluorescent lamp is very useful if the power goes out or can be used in a dark place with no electricity, but can use the battery 12V. This 12V fluorescent lamp circuit i have tried and the results are bright, durable until decades. You can use 12Volt fluorescent lamps up to 40W. Use quality 12 Volt fluorescent lamp, do not use the fast heat, because the fast was also damage the transistor at 12Volt fluorescent lamp circuit . Do not occasionally mistaken in putting up the transistor .

R1 = 220R/0.5W
R2 = 1/0.5W
C1 = 100n/100V
C2 = 220uF/50V
Q1 = D1885/D1710
A/B= To A fluorescent lamp/ and B to B fluorescent Lamp and just use one pin
B = Battery 12 volt with currents above 5A
Roll of copper wire on ferrite rod, with :
L1 = 1.2 mm diameter wire with many loops winding 20 times
L2 = 1.2mm diameter wire with many loops winding 20 times , and connected after the L1
L3 = 0.8mm diameter wire with many loops winding 500 times , connected after L2 and wrapped over L1 and L2.
F = Ferrite rod diameter of 10 mm
Number 1 - 4 in red will be connected to the winding.
