simple circuit using stripboard (component side)

There are many types of "perforated prototyping board".

The vast majority of such boards are perforated at 10 holes per inch both horizontally and vertically (also called "tenth inch spacing"), made out of either "synthetic resin bonded paper" or fiberglass, and have some kind of copper pattern on one or both sides of the board.

Perhaps the most popular pattern is "stripboard" -- which has wide strips of copper running one way all the way along one side of the board, but no copper on the other side.

Because the strips (copper traces on the solder side) run left-and-right, the components (on the component size) usually run up-and-down.

Complex circuits, such as Dolby SR, have been built on stripboard.
