This months issue includes three circuits: a touch switch, stun gun,
and an FM Bug. These are all simple circuits for beginners and should
cost under $10 each to make.

First is the touch switch. Any time a person touches the plate, the
output of this circuit goes to the high level and is capable of
directly controlling a load such as a lamp, relay or bell.
