"RE: Wild life Photography"

I Have been doing some development of this idea. i built a transmitter and receiver circuit with limited success. i found this link http://pcbheaven.com/circuitpages/Long_Range_IR_Beam_Break_Detector/?p=0
The advantage of this is that it will use a lot less current than i was wanting anticipating, because it has a timer that only transmits a signal with a low duty cycle. When i get the spares and build it i will give a report on how it works.
