RepRaps, Makerbots, Printrbots, String-drawing robots... you see these devices all over the open-source hardware world these days, and yo know what they have in common? Stepper motors. They're relatively cheap, precise, powerful, and ... a son-f-a-gun to make move properly. But since big IC companies also see how useful they are, there's a large variety of ways to connect and power the 4, 6, & 8 wires that are needed to make a stepper motor move. And Pololu does a great job of making boards that use these chips!
