This is how to modify the electronic fly swatter increasing the power level output from 800 volts at around 1800 volts.
This is a duel button unit where both buttons need to be depressed to activate it. I have used one of the buttons to allow it to function in normal mode and bypassed the need to hold both to operate it.
When using this in high power mod mode or 'Evil' mode as I like to call it! be aware that the grid will hold a charge for up to 5 minutes. To discharge it hold the modded button and then press the other button for 3 or more seconds, let go of the non-modded button before the modded button to be certain it has discharged.
Touching the electronic grid before modification is unpleasant to say the least, however touching it in its modified mode just plain hurts so avoid it unless your some sort of pain freak!
