OR Gate From NAND Gate
Intro: OR Gate From NAND Gate
Sometimes when you're building circuits, you dont always have the right components. Fortunately when it comes to digital logic gates, you can make the component you need! If you're fresh out of OR gates, but have some NAND gates laying around, you're in luck! With three NAND gates, you can construct an effective OR gate! This can be done with the circuit outlined in the attached photograph.

Also, some additional explanation (truth tables, quoting Demorgan's theorems, etc) would be nice.
I once bought a lot of NAND gate chips, based partially on this principle.
