I'm trying to build a circuit to make a pop up target stand up automatically once shot down. I preferably would like to use a geared dc motor, stepper motor or rc servo. Im using a $8 dollar large hinge from home depot as the target. Id like for the target to be reset randomly within a 10 second period after it has been shot down. Id like to make several of these self contained with its own battery supply and enclose in a metal box to keep it from getting damaged from the rain and from the .22 cal. pellets. I know how to build a circuit, i just need the design diagram schematic to build it.
