Cats, teenagers, kids: at least one of them likes to use my garden as a toilet, but fortunately they can all be repelled with some simple electronics. I'm going to use a 555 astable to produce a high frequency square(ish) wave signal that should range from annoying to painful for the "targets", whilst remaining inaudible for most adult humans. Do bear in mind that R1 should be at least 1kR.12,000 = 1.44/((R1 + 2R2)C)1.44/12,000 = (R1+2R2)C1.44/(12,000 x 0.0000001) = R1 + 2R2 = 1200I've used 100nF as my value for the capacitor, and I'll use a 1kR resistor R1 and a 100R for R2.As I'll be using a 9V PP3 battery for +Vs, and my red LED has a voltage drop of 2V and draws 30mA of current, I ideally need R3 to be 233.3R. 

 

Even though there are chemicals that are produced to control electronic mouse repellent, there are other easy and organic and natural techniques that just one can use to command this menace and hold their greens or foodstuff increasing healthier. The initially 1 is using compost manure which has distinctive nutrition that the plants need to battle the health conditions and pests. Preserving a Pest Cost free Greenhouse Expanding vegetation in a greenhouse provides you the option to manage the setting on a every day foundation. 

 

There are some pretty deadly snakes out there that will harm your dog if allowed to do so. Your dog cannot think for himself and only reacts on instinct.

If only i had checked the internet first. There are many places that say it doesnt seem to work on anything but ants.
