I want to build a stable and safe circuit that would fry mosquitoes. can I use my eliminator transformer (3 volts 0.5 amp ( 3-0-3) iron core) as the step up transformer to develop up to 300 v and the LM555 to convert the 3 V DC to charge the transformer? then the diode capacitor voltage doubler 4-5 stages would be used to generate the 2-3 Kv. but i have some difficulties. I read in many circuits that 400 v polyester film capacitors were enough. but for 2-3 kv would they be? or shall I use 3 kv disc capacitors and 4007 diodes? I saw that there was a capacior in the YPD zapper across the +ve n negative terminal (HV). can I also connect such a capacitor? then of what value? if i am making 3 kv then is 5 kv capacitor suitable to connect across the positive and negative Hv terminals? are 4007 enough or i need to have some high voltage diodes?? is the transformer suitable or i need to use the ferrite core transformers? please help me friends.
