Well, ever since the media has been reporting the "teenbuzz" ringtone...i wondered if it really worked...

So i tried to recreate the effect on our very own computer...

a c++ program...

#include

int main(void)
{

sound(12900); //change the frequency
delay(1000);
nosound();
return 0;
}
[/b]

the program generates a "beep" for one second of the given frequency...(The CPU beeps not your speakers...)

if your over 30 you'll not be able to hear it...hahahaha...

my parents could hear below 12900....

i hope you guys can compile? :blink: :mellow: 🤔
have fun...🙂
 
Interesting!
 
Internal speaker is tied to the buffered output of the 8254 timer chip on all PCs. Output of the 8254 timer is further latched through port 61h. Just replace "sound" function with ASM block that wites this value to 61h. And replace "delay" with spin locks.Now you have a ringtone that will compile and run on DOS,Windows,Linux,Solaris,Mac OS,BSD..... as long as it is on x86 🙂
 
i will still go for an ALL OUT 😛 😀 with extra MMR(Mosquito Mortality Rate)
 
Not very effective from what i've read around the net. In other wrds *BOGUS* but you can't stop the gullible.

If you really want to keep mosquitoes away use DEET. But its not healthy in the long run 🙁 so most effective consumer varieties have maybe 10-30% DEET in them.

I recall reading about this ultrasound repeller in the TOI some time back, which prompted a googe search. Shame on whomever reported it, must have been on the take for whoever is selling this shit. That's another thing you got to watch out for nowadays, so called informative articles that are no better than infomercials.
 
There is also something about chicken brains exploding if you play a sound of 7000Hz (I am not sure about the frequency) its given in the help section of borland c++ compiler.
 
its actually 7Hz...and the story is proabbly false...

How to run the program
[/b]

you need to compile it with C++ Compiler...

I'll try and upload a Zipped Exe later...
 
a single frequency for a short duration is
never effective on the mosquitoes .
we have to produce different range of frequencies
for long durations . and the output needs to be
amplified to throw out mosquitoes ...

electronic ultrasonic mosquito repellers use a set
of frequencies & special type of speakers . They
claim much & affect less !

pls see the following post
"Mosquito" is just the Name of the Gadget....[/b]
I confess my ignorance ... okay
 
hey! "Mosquito" is just the Name of the Gadget....The real device is meant for teenagers...not mosquito's
 
dude, chicken skulls crack at 7Hz. And its not a myth its reality. 7Hz is the resonant frequency! 😛
