I prefer you buying one.  But there are always schematics out there that show you how to create your own inverters.  \n\nhttp://www.aaroncake.net/circuits/inverter.htm

A block diagram shows the basic functions of a system or circuit and which subsystems perform which functions.\nA system diagram shows the general wiring without showing subsystem details, sometimes showing the physical locations of parts.\nA circuit diagram shows detailed connections between all basic components.\nA wiring diagram shows wire markings and labels, and how wires are physically connected to subsystems or external systems.
