10n60a Power Supply Circuit Diagram
Things that you will need to make this power supply is. Piece of veroboard. Four 1N4001 diodes. LM7812 regulator. Transformer that has an output of 14v - 35v AC with an output current between 100mA to 1A, depending how much power you will need. (I found a 16v 200mA transformer in a broken alarm clock.). 1000uF - 4700uF capacitor.
Here this circuit diagram is for +12V regulated (fixed voltage) DC power supply.This power supply circuit diagram is ideal for an average current requirement of 1Amp. This circuit is based on IC LM7812.It is a 3-terminal (+ve) voltage regulator IC. It has short circuit protection. We design various type of power supply circuit like regulated power supply, digital control power supply, universal power supply etc. Our goal is to publish every types of power supply circuit need to operate electronic gadget. We posted 20 various types of power supply circuit and counting.

1uF capacitor. Two 100nF capacitors. Jumper wires (I used some plain wire as jumper wires). Heatsink (optional)You should be able you get most (maybe all) of the parts at Radio Shack or Maplin. If you want a 5 volt power supply, just simply replace the LM7812 to a LM7805 regulator. If you are going to pull out about 1 amp from this power supply, you will need a heatsink for the regulator, otherwise it will generate very high temperatures and possibly burn out. However, if you are just going to pull out a few hundred milliamps (lower than 500mA) from it, you won't need a heatsink for the regulator, but it may get a little bit warm.

Also, heres the schematic. I also add in an LED to make sure the power supply is working.

You can add in an LED if you want.
