DIY Electric Fly Trap 2000V 300 flies in one day

Only 2000V at the moment but outputs a lot more current than a standard fly zapper. Will upgrade it to about 6000V maybe more when the new parts arrive.

I am currently using a half wave 'voltage multiplier' stepping up from isolated mains @ 240V up to around 2000V. Deadly and dangerous - Using 1uF 250V AC capacitors (there is ~500V DC across each one, but I read that AC capacitors are rated ~3x the voltage than DC)

The bucket is holding half a days worth of flies. Had a hit count earlier this day of about 1 fly every 5 seconds.

Bigger spark will hopefully kill them a little better, and possibly kill them better also.
They seem to be quite high in resistance, so a higher voltage should help burn them off and be more humane in terms of killing.

Will also need to build a better grill, so that the flies fall off it better

add some caps

@masry2011able the fly touch 2000V (normally AC) and the ground (0Volt) with a X amount of current (amp) so the fly is literally fried in milisecond (the electricity flow tru his little body). you dont have to bother about making a short circuit, just put a couple of capacitor and you will be allright.

I need one of this will u mind to share the info with me?

[masry2011able]

what the principle to do that??? is the insect touches 2 grids (2000 V ) with its body ??? so if that happen may be we will get short circuited for a moment ....is it right???

haha thats disgusting and cool at the same time
