RadioShack is also getting into the Halloween spirit with its own contest, the Halloween Great Create Challenge. Build something scary for Halloween with RadioShack parts and take some photos or video and you can enter. Winners get a $250 gift certificate.

So are you planning on making something cool with electronics for the Instructables Halloween Contest? Why not enter both! You could always use more parts for more projects, right?
