Well, to design 12V power supply is easy. You need following components:
Four 1N4001 diodes
LM7812 (LM7805 for 5V) regulator
A transformer must produce an output of 14v - 35v AC with an output current within 100mA to 1A, depending on the power you will need. You will easily get one in store or can buy online.
1000uF - 4700uF capacitor
1uF capacitor
Two 100nF capacitors
Jumper wires
Heatsink if required

Further, you will need the tools to make this power supply.

Soldering iron
Wire cutters
Wire strippers
A thing you can cut Veroboard tracks.
Hot glue

Just follow the circuit and shoulder this all on GPB as per the figure.
