Keep the deer away

A.C. fishing · 2006-05-22 23:25

Finished a new project! It is useful for those of us that have deer come and dine on our flowers and shrubs. It is a VEX ultrasonic module attached to a BOE,·with a pan/tilt system, two continuous·servos.·The device emits changing Ultrasonic frequencies into the air in every direction the pan/tilt allows. The changing frequencies can be picked up by deer within about 15 ft(an approximate.). It irritates them, and they go away!·The idea is already·patented by a company·.(without the BS2 or Pan/tilt). After a lot of tests, i decided it worked.
Please post any comments or questions.

Now this someting that i need to make for my Mother
She has the same problem with them Deer come and Dine
On the new leaves of her fruit trees she work so hard on these tree

So this works

And the Rackcones eat all the fruit off of the trees and leave nothing behind

Do you think this will work on them as well

So where do i get these part from ( Please part # )
VEX Ultrasonic Module and a Pan/Tilt System

........ Now pan/tilt system................

.........Are they two continuous servos or are these two different parts.........

The devices are in
WHAT TYPE OF CASES

VEX ultrasonic module , with a pan/tilt system, two continuous servos.

Do you have a schematic for this Project

Thank You For Any Help That You Can Give Me In This Matter And For Your Time

Sam

I don't know about raccoons. I made mine because I was going to buy a few from the company that sells them. You might have to vary the frequencies, but raccoons probaby have a different hearing range. This will work much better garding trees, because it only has about 3-5 ft of range.(approx.). The VEX module:
http://www.radioshack.com/product/index.jsp?productId=2131179&cp=2032062.2032398.2032404&allCount=21&fbn=Type/Interactive&f=PAD/Product+Type/Interactive&fbc=1&parentPage=family
the pan/tilt is simple homemade using two continous servos.
The schematic is easy:
two servos attached to 12 and 13.
The orange wire on input connected to P0.
The red one on input connected to Vdd
and BOTH black wires attached to Vss.

I'm saving one of your questions for last.
So this works?
Me and a few friends agree yes. Considering the basic concept was patented, we know the idea works. I ran quite a few tests. The deer are such a problem, you can come 2 feet up to them before they run away. Some tests I run:
Have your unit guard a cabbage, fruit, or plant, for a few days. See if it was munched on by any deer. I would repeat this test again, and then also repeat it with different bait
Walk up to a deer, nice and calmly, and see if the device seems to have any effect on the deer.
With raccoons, it would be easier to test. Just have it guard a shiny object!
Well, my device seemmed to work, after fiddling around with the frequencies. I tried I think it was 12 tests, and wrote detailed results about each. Rememeber, repetition is everything. Somethimes, what is just a coincidence, you might think is a successful test, because you want to think that.
Hope this helps,

One thing to note with the posted code in case it causes any trouble for anyone is that the COM directive being used locks this code to COM Port 4.· Your COM Port may be something else and this code would not download without changing it.· COM directives help when you have more than one BASIC Stamp connected to different ports and want to direct code to specific ports, but in this case you don't know what the person running it has, so it's best not to include it in released code.

Isn't the ultrasonic the same as this:

In which case, how do you vary the frequency output??

Shawn,

·· Presumably a piezo speaker was used.· Perhaps A.C. should post pictures and schematic?· Anything over about 20 KHz is generally considered ultrasonic (above human hearing range).· Inherently many devices generate harmonics which we can hear (some people).· My parents used to have an ultrasonic remote for our TV which I could always hear, although it was most assuredly the lower harmonics.

It isn't the same as the ping)). Anyway, send a freqout down a VEX ultrasonic at a low frequency. Like FREQOUT 0, 10, 2000
You should hear it, just like a piezo speaker. Attach black to Vss, and Red to Vdd to boost power. So I figured that It could work just like a Piezo speaker, with a greater range. So I sent down some harmonics, and it seems to have an effect on some dogs, so I highed the harmonics, and it clearly after many tests showed to have an annoyying effect on deer, and they would run away. The schematic is very easy:
VEX input wires:
black = Vss
Red = Vdd
Orange = P0
VEX output wires:
black = Vss
there you go!
I'll get up some pictures,

In an application such as this it would be helpful to know what frequencies work best with whatever rodent or animal you're trying to annoy.·

Hmmm...
Birds heaing range = 2000 to 4000?
Raccoons= 100- 40000 hz
the hearing range of deer is between 2 and 6 kHz
(link):
http://www.wildlifeaccidents.ca/highway_managers.htm
But does that mean These are frauds, and my device is a fraud too???

http://www.hornetnorthwest.com/index.html
http://www.naturetechnologies.com/
Both of these use ultrasonic waves to keep away deer. In fact, I even had a nature tech. guy come over tomy house, and he explained it. But deer can't hear ultrasonic? The deer tech modules use around 40 kHz he said. And my module did pass a lot of tests...
And they patented their device...?
Well, at least it will work with racoons...
Hmmm...,

I'm not discounting your device or its effects...Please do not take it that way.· I am merely saying if one was to build their own and be effective they would need to do research.· It appears you have done that.

Just because something is patented doesn't mean it works. I read an excerpt from a real, issued patent the other day that said it implemented faster-than-light communication through a fracture it generated in the space/time continuum.

I'm not blaming you chris. Not at all. It is a good thing you metioned what you did. I decided to do some research for other people, just like you suggested. I suggested my device doesn't work because of my research, not anything you said. I always thought that the deer could hear the ultrasonic signals, but it appears that they can't. Well, I'm cancelling my deer tech orders...
Maybe they somehow can sense the ultrrasonic signals, because a lot of my tests couldn't have been coincidences. Like the deer munch on the hostas every night, and for a whole two week, the hostas never showed any signs of being eaten. I took digital pictures to compare the plants. I will look more in to this

quick question · 2006-06-01 10:08

I heard an interesting piece on NPR this weekend.

appearantly a guy in England came up with a system to keep teenagers away. He is selling the heck out of it.

He was pulsing tones above 17khz. Appearently as you get older,· you loose the higher range hearing, so at over 20 years, you can't hear his signal.

His daughter was also on the radio. appearently her firends put the about 17khz tone on ringtones so the teachers can't hear them ....

Pretty cool - An alarm clock that will bug my (soon to be teenagers - but not me!)

"Though he did not know it at the time, the idea came to Howard Stapleton when he was 12 and visiting a factory with his father, a manufacturing executive in London. Opening the door to a room where workers were using high-frequency welding equipment, he found he could not bear to go inside.

“The noise!” he complained.

“What noise?” the grownups asked.

Now 39, Stapleton has taken the lesson he learned that day - that children can hear sounds at higher frequencies than adults can - to fashion a novel device that he hopes will provide a solution to the eternal problem of obstreperous teenagers who hang around outside stores and cause trouble.

A trip to Spar here in Barry confirmed the strange truth of the phenomenon…..The Mosquito is positioned just outside the door. Although this reporter could not hear anything, being too old, several young people attested to the fact that yes, there wasThe Mosquito is positioned just outside the door. Although this reporter could not hear anything, being too old, several young people attested to the fact that yes, there was a noise, and yes, it was extremely annoying.

Yeah I heard about that a little while ago, it's to prevent the chavs from hanging around and engaging in hooliganism.

I had (and still to a lesser degree now) the problem when walking through an entertainment section of a store with tens of televisions on, the high pitch whine of the scanning beam drove me nuts, my mom never heard it.

I used to be able to tell upon entering the house if the television was on by the sound of the scanning beam. I assumed that new TVs had been improved so that the sound was eliminated but it turned out instead that it was my ears that were "improved".

It seems to me that if the deer really cannot hear the ultrasound, you could still use the ultrasound sensor to detect their proimity [noparse][[/noparse]or a PIR] and trigger some high intensity LEDs in a strobe.

I suspect the unpredictible and intense strobe might shy them away - especially multiple locations.
