How To Make Mosquito Killer?
Note: Keep away your children & pets from this circuit & take safety measure as required.
For making Mosquito grabber we need two different size of Aluminum Mesh, there are total 3 layers of meshes used here to make insect grabber. Size of the mesh depends on the size of Insects.
We have to keep plastic insulator in any shape between 2 meshes so that all 3 meshes not come in contact with each other. We can make any shape size of enclosure.
Middle mesh should be smaller in size than outer & Lower mesh (Actually Mesh 1 & Mesh 3 should be of same size) so that smaller insect will not escape easily.
We can use Any type of outer Nonconductive Body say Wooden or Plastic BOX. We can make device work on the Battery.
Now sharing circuit for Battery Operated insect killer.
You can install UV or Blue LED to attract insects. Also for continuous use we can eliminate Push button switch & put the On/Off switch.
While charging Battery in this circuit always keep SW1 Off. We also modify the circuit to use Li-ion Battery 18650 with charging Module.
