How Mosquito Racket works?


1. Power Supply
2. Oscillator
3. Transformer(Step-up)
4, Final mesh-nets

The circuit consists of a flyback topology transformer driven by a general NPN transistor 2SD965.

The feedback coil of transformer is of 10 turns, the primary is of 40 turns and the output or secondary coil is of 450 turns (40:450).

When this circuit is run by giving input of 3 Volts, the transformer generates about 2000-4000 volts at zero load, and the output is then coupled 3 times by using three IN4007 diodes and suitable capacitors, thus reaching our need of 5000-10,000 volts.

  The moment a mosquito or any bug comes in contact with the meshes, the stored high voltage in the capacitor discharges violently through the body of the entangled bug creating a big spark and electrocuting it instantly.


  1. I have visited your site all the sites are really good but if you really interested in technology then visit our site.

    It seems like over and over again we're hearing about people who DJI ground station are losing control of their Phantoms, but I have never experienced this. DJI makes the best multirotors out there, and if you just get a little bit of training before you fly you'll be fine. I have attended three "Drones 101" classes at UAVDirect in Texas phantom 2 drone , and I have never had so much as a nick on my propellers uav flight controller . They really reinforce pre-flight checks and calibrations before taking off. I can't tell you enough phantom 2 how much their classes have made me fly like a badass.
