Dual Regulated Power Supply

Dual Regulated Power Supply. There are 3 output that are (+) voltage, (0)(GND) Grounding, and (-) voltage. The current output max about 300-500 mA.

You need Center Tap (CT) transformer. for example, if you need 12v output, you should connect J1 to 15v transformer output, J2 connected to 0v and J3 connected to CT.

Make Your Own Printed Circuit Boards (PCB)
Make a PCB in very easy steps..! Create your PCB design using PCB designer software like Eagle, print out your design on photo paper or glossy paper or paper calendar with laserjet printer. Stick the printed design on the PCB (copper side) and then heat it using hot iron plate. The ink will stick on the PCB and it will be ready for etching process.

Note: If you don't have laserjet printer, then you can print the design on A3 paper. Copy the printed design at Copy Service around your location (with glossy paper).
