Top Cat Phase II P1235 2 Engineering Specs: •Detection Range of 25’ •Safe Deterrent •0.8”x1”x0.5” Enclosure •Does not restrict cat’s movement (Light weight) Team Members: Mahdi Massey – EE Brian Rosenberger – EE Andrew Strobel – EE Tsz Hang Yung - EE Mission Statement: Goal of this project is to develop two short range alert devices that will fit on two collars to prevent cats from fighting Faculty Guide: George Slack Sponsor: David Perlman Blue Trace is the IR Receiver, when the receiver goes low, the 555 timer outputs a 25kHz signal to the output speaker (Yellow Trace) Both collars are transmitting a burst of a 33kHz IR signal and looking for a 33kHz signal. When this signal is detected, this triggers the 555 timer to output a 25kHz audio pulse. To prevent the collars from detecting it’s own signal, an inverter was used to turn off the detector when the circuit was transmitting. Test Results: •Detection range of 40’ indoors and 11’ outdoors •Deterrent is a 25kHz high frequency sound •Size is 2.5”x1.5”x1.0” •Battery life of greater than 12 hours on standby Technologies: •IR for collar detection •RF signal to alert the owner •High Frequency sound for deterrent Final Product outside of enclosure
