Here are two useful articles I’ve read from IEEE Spectrum that are useful for organizing with the rest of my electronics blog information. You can construct small, low-power DC motors via a printed circuit board: the motor windings are trace patterns printed onto your circuit board.

The second one, the “dead bug” approach to constructing prototype high-speed circuits. You can’t construct high-speed circuits on a conventional perfboard because you don’t have a large grounding plane. So instead, you can use an unprinted circuit board as your large ground plane, and wire together your IC chips directly, with them upside-down like “deada bugs.”
