Hi all.
I know many sources says that these devices are not practical and so... I have an electronics store and I sell some of them. I've tried on model of a mosquito repeller and it really worked well, this model doesn't cover a big room but only about 3m x 4m maximum. You can see this device on my website, see it in the bottom at the right in this page: http://www.etcenter.co/animal-repellant.html
This one costs about 10$ while the one in the first picture in the page should be better as it's much expensive (about 25$).
Now, I'm looking forward making an ultrasonic repeller for very very annoying and tiny flying insects comes in summer at hot weather here in Lebanon. I don't know their name in English. I may let the frequency variable a little like that of the mosquito repeller I tried, and I may put a trimmer potentiometer to vary the center frequency in the experimental circuit.
I reverse-engineered the circuit of that mosquito repeller to benefit from it, and put it in this thread for you to see.
To help you understand the circuit well, when the switch is switched to the other way, the device gives a low frequency sound that can be heard, it's as they say the sound of the dragonfly that makes the mosquito go away when it hear it. The current position of the switch gives the ultrasonic sound, sme sources says that ultrasonic sound is the sound of the mosquito male where mosquito females goes away when they here it (except once a year )

So I want to hear your opinion, ideas and suggestions, hoping to build a practical ultrasonic repeller for those flying insects that come every summer.
