The first picture is the circuit that is to be etched onto the PCB, the second picture shows where everything should go.

*Your looking at the side with the copper foil, so watch the polarity when putting in the components

I dont really want to etch a board or drill holes is three any other option

Long time, I know but if I don't have a board to play with, I solder everything and use hot glue to make sure everything is isolated. Hardly a final product but it gets some use as I learn.

As chrisstoll said, the middle pin of the voltage regulator is supposed to be connected to ground (negative), and the others are input and output (posotive).

Isn't the inside connector on the voltage regulator ground? And not the outside one as shown in the diagram?

Would you mind doing a more detailed walkthrough, and maybe adding more pictures to guide us.
