Cool! Just some pointers on using PCBs: The little copper bits around the holes are meant to be used to solder onto (see pic). This provides a cleaner, sturdier finished product. Besides that, this is a nice project!

OOOOOOOOHHH really? Nice. Well I love the project either way "P

I understand what you mean, that's what I tried to do. I just little new to soldering.

I think you were soldering on the wrong side of the board.

IT would have worked like the picture posted by radioactive_legos if you just flipped it around.

Ive used the same type of board, it doesn't have the copper rings it was just blank on both sides. They work fine just a lot cheaper than the copper hole ones.
