problem with frequency & snakes :(

Hello sir

While googling i found so many circuits using 555 741 etc etc for generating high frequencies like 40 khz or more or less , Not sure but now i guess as a result everyday one or two snake is trying to enter the area where i am doing experiments , we hv already implant precautions & safety but now the matter is going serious . . they still try to enter infact presently roaming out of boundary area

Now we are planning to discuss with forest authorities here . .
please help me to let these creature stay away from my housing perimeter or people in vicinity ll not allow me to make practicals no matter how much i am doing for sake of our race

I am not sure if it is going on like what i am thinking but if it true then i need help :-x

I may be wrong but I think snakes are deaf so ultrasonics proably won't work. I think they see in IR light though so perhaps a boundary of IR LEDs might keep them away.

I can't experiment for you - the only snakes in my locality are 30cm long, perfectly safe (we pick them up and put them somewhere safe so we don't step on them!) and are not common anyway.

Snakes aren't totally deaf but lack middle-ear structures so that all sound vibrations are transmitted from the ground to the inner ear through the bones of the jaw and skull (according to my Paul Morrison book). That is probably why snake repellers are a bit like mole ones - transmitting vibration through the ground.

no no sir no need to make practicals , i ll make that & we to have such lenghts of snake here :razz:

sir thanks for advice but as you said infra red rays help them to see so if i make such boundaries then don't you think we are making ways for the creature so as make signals to attract ?

our idea can inversly work , isn't possible ?

oh woww ok sir nice thanks a lot
Do u have any idea about the internal of the device ? what kind of device is the rod like structure ?

I think they use IR radiation from small animals (and humans sometimes!) to find their food. Keith is almost certainly right that they sense ground vibrations as well. Hopefully lots of IR would make it look like something to stay away from - but then they might think it's a big meal!

The "thumpers" I have seen use a metal spike which runs inside the body up to the top. The noise is made by a multivibrator circuit running at slow speed (< 1Hz) which drives a solenoid so it hits the top of the spike. The sound conducts down into the ground along the spike. It should be easy to make one experimentally, I have not tried this but it seems a sensible way to start:

Get a ferrous metal rod about 30cm long. Find a plastic tube, about 5cm long that fits close around it but is free to move. Block the end of the tube with something hard, either a metal slug or maybe a big nut, this is to be the hammer. Wind a coil of fine wire around the plastic tube and attach two flexible wires to the ends. With the rod upright, slide the tube over it so the hammer sits on the end of it. Now when a current is passed through the coil it should lift the tube up a little and when the current is removed it will fall again and strike the end of the rad to make the noise. When that works, hook the coil wires up to a slow oscillator so it repeatedly hammers the rod.

In that case, just keep your circuits above ground level...that should work ;-)

Re: problem with frequency &amp; snakes

RajaRam my friend what snakes are involved, venomous ?

Try to put ash or sulfur (sulfur is best after mungose) on their path of movement, and around entry area (door, window, around tree, ...), or get Mungose.

This is not case for electronics.

RajaRam do you have owls in your country ?

hehe ya ya we have owls & actually i was searching for some circuitry function which you can see in some above posts & you will find an electronic item :grin:

ya its 3 feet above the ground level i ve my arrangments

Re: problem with frequency &amp; snakes

My thinking about this is not good. There is lots of snakes, with different types of systems for target tracking, detecting and attacking. Its not smart to play with these devices without proof (atest). First you should identify and introduce yourself with snake types in your country (location). In some countries you need a lot of luck to avoid snakes.

Use sulfur if you want to keep snakes far from your place!

You have greater chance to attract than to get rid of snakes with electronic devices, specially with vibrations.

ya exactly & thats going on with me now a days , kkk i agree n ll go with sulphur

sir any other full proof remedy like that ?

If you have big snakes you need big Owls. Settle owls and protect them from humans.

Now only it come to know that Owls too eat snakes. 8-O

@ Rajaram: If u create continuous or periodic vibration (or sound or light) it'll get accustomed or habitude for animals (humans too).
So generate random (random time and random amplitude level).
Preferably random pulse for few sec and few sec delay (off) again random pulse then delay like this sequence.

If u generate random IR pulsed light that too will affect its visibility. (like camera flasher for us)

Alternatively you can use mobile phone vibrator to generate small vibration. If u make proper mounting that will be enough and it'll cover few meters of area.

I predict seismic events around Rajaram's house! (and maybe UFO reports too - strange flashing lights....)
:-D

yo yo much better idea to be a super hero then :-o
In case i don't hv to design such circuits discussed all here in the forum :twisted:
I ll hv my power built in my body

ya okk sir all this idea i ll try to implant with a full proof plan & trying to do the best . . thanks for the info above

Yes, they kill and eat snakes very effectively, also mouses, rats,....

Just use Google for searching photos, videos,....

Yes. I googled it & saw many photos.
