Hello!  This is a "test map" of all the devices that I can think of.  All it is is a bunch of redstone devices with either a broad usage or a specific usage that can be used in any, or even your, redstone mechanisms.  These are all thought up by myself and one of my friends except the gates.  Enjoy!
