How to make a Mosquito Repeller

This circuit is intended to drive-off the female mosquitoes with a super sonic sounder. Most of the time when a mosquito is pregnant, she needs more valuable food and will look for humans or other sources of nutrition. In the meantime, she dislikes keeping in close with the male mosquitoes and prefers to look for food alone. Thus, this circuit is intended to produce a sonic frequency range that drives-off the female mosquito.
The two transistors link as a multi-vibrator oscillator circuit while R1, R3, and C2 control the super sonic frequency. The piezo element is the sounder.

bro this is nice...I don't know any word about electronics....But this Idea made me interesting....Will I able to make this my own..?
Will any body help me out this..

How can I buy the Equipments..The circuit board & so on.....

Will I able to buy the circuit board by searching the model number you  have given here...?

Hi,

visit an electronic shop to buy parts, but i don't think you will can find the circuit board. This is a simple circuit, anyone can make it.

dear saman,

16k resistors can't find in lanka. will 18k suitable for it?
it will change the frequency!

You can try 18K which will make a a slight shift in frequency. Better do an experiment.

Also, you may all put few resistors in series to make 16 L as well.
