Abstract:
A rodent control device, comprising:a) an AC line voltage input with first and second power terminals being respectively connectable to corresponding first and second leads of an AC line voltage source; b) a programmed microprocessor; c) a power supply connected between said line voltage input and said microprocessor to provide rectified DC power to a power input of said microprocessor; d) one of said first and second power terminals being connected to an interrupt input of said microprocessor to generate an interrupt with each cycle of said line voltage source; e) a coil; and f) a switch controlled by a gate connected to a control output of said microprocessor, said switch being operative, in response to a gate control signal from said microprocessor, to selectively close a circuit between one side of said coil and one of said first and second power terminals, an opposite side of said coil being connected to the other of said first and second power terminals, said microprocessor being programmed to periodically send said gate control signal to said gate based upon a predetermined timing cycle controlled by the frequency of line cycle signals received by said microprocessor interrupt input.
