Hi There,
Now I no longer have a dog to carry out the work I wish to make a picaxe controlled device to prevent the local
cats from using my front and rear gardens as a loo. I am prohibited by my wife from using the more robust methods
of prevention like a 12 bore, traps or even bricks dropped from a height (not that I own any of these items, but no doubt
could aquire a brick or two quite easily).
So what I would like to ask anybody with practical knowledge of such things the following:-
1/. What is the best way to detect a cat, both at night and during the day? What sort of range is possible?
2/. I am considering Ultrasonic transducers, but can a Cat hear sounds up to 40Khz? If they can could this
this frequency be used to deter them?
3/. How effective would a P.I.R. detector be? Would it work in daylight?
4/. I am considering using flashing LEDs to mimic an animals eyes to act as a deterent, is this effective?
5/. Using water jets to deter the little beasts is an appealing solution but I would like to have a small self contained
unit that does not have trailing hoses, so is there any other way (thats legal) to provide a effective deterent?
Many thanks Clockwork
