I started this instructable about half through building the zapper, sorry for lack of images and details i realize my instructions may be kinda confusing.
How bug zappers work:
This zapper does not have the power of a normal one but it does produce a few hundred volts which should be enough to kill most insects.
I haven't been able to test this outside yet because the bugs have come out yet but when I complete the circuit with a metal wire a loud snap and spark are produced.
Step 1: Overview/ Materials
- disposable camera w/ flash
- 3x 10mm blue leds (apparently mosquitoes are attracted to blue light)
- large cooking sifter
- small fish trap (available at walmart for about 1.99)
-spray can cap
Step 2: Creating the electric shock
Remove the wrapping from the camera and use a screwdriver to pry it open -be careful not the ruin the case
Remove the film and locate the capacitor which should be in the upper right corner.
Take two five inch long pieces of wire and solder one to each of the leads of the capacitor.
Drill two holes large enough to fit the wires through next to the view finder.
String the two wires through and close the case.
**There are a couple loose parts inside the camera make sure you put them back in the same place.**
