Electric Mosquito Zapper Circuit

The oscillator transistor used in this chinese mosquito zapper circuit is a 2n5609 which is an npn bjt having a current handling capacity of around 1 amp however other similar variants such as 8050 2n2222 d880 etc can also be tried instead of the original number in the design.

Electric mosquito zapper circuit.

The concepts of electronic mosquito repellers are simple and we can build a simple mosquito repellent circuit at home easily by using 555 timer ic and few other commonly available components. Ever want to build your own mosquito killing device. Bug zappers can lure and kill more than 10 000 insects in a single evening. Hoont powerful electric indoor bug.

This ultraviolet fluorescent lamp is mounted in the middle of the cabinet and a pair of carefully spaced electrically insulated charged wire grids surround the light. In doing so we are going to take out the following. The design is an electric fly swatter circuit that looks like a tennis racket. High v oltage electric current flows through the insect and vaporizes it.

The circuit inside these magnificent devices though is complex and involves several voltage booster stages which is finally stepped up to several thousand volts. This rechargeable lantern doubles. Check out our circuit plans for making your own indoor electric mosquito zapper. Another possibility was to use a small step down transformer as a step up transformer and rectify the voltage to dc using general purpose diodes to apply to the mesh.

A mosquito killer bat is also called electric flyswatter mosquito bat racket zapper or zap racket these devices are hand held and similar to look badminton racket or tennis racket. This hanging bug zapper s 40 watt light does a fantastic. When this circuit is applied as a mosquito swatter the end terminals of the 2uf capacitor are appropriately tied or connected across the internal and the external bat mesh layers. In my design i decided to build a portable bug zapper because i already had most of the parts from a useless rechargeable lantern.

Yellow resistor black transistor red led gray diode blue capacitor brown switch or wire battery is on the left high voltage output on the right. This is a demonstration to replicate the mosquito racket fly swatter bug zapper high voltage circuit. As the bug flies toward the light it penetrates the space between the wire mesh grids and completes the electric circuit. An electric fly swatter is one such device with a high voltage electrocuting circuit and an insect attracting uv lamp of 365 nm wavelength.

For the purpose of learning i have tear down a small mosquito zapper racket. The meshes are placed on a plastic tennis like racket the inner mesh if where the. You often hear a loud zzzz sound when this happens.
