    1) Fuse.
    2) Switch (optional)
    3) Transformer, 220VAC primary, 6.3v to 12v secondary.
    4) Bridge rectifier.
    5) Filter capacitor(s), depending on desired current.
    6) Regulator IC, with 0.1uF caps on the input and output, complete with heat sink.

    Or, google "ATX Bench Supply" for cheap ideas on converting a spare ATX form factor computer power supply to a bench supply.

    If you have any old cellphones, check the chargers, they should end with around 5vdc.

    Depending on your current requirements, SgtWookies got it covered.

    Both Sgt Wookie and retched offer the right advice - you can either buy a wall transformer which can handle 220VAC in, and outputs a 5VDC regulated output - or you can build one yourself.

    it depends on what you need it for, and if you are interested in learning or just need a problem solved.
