LOL it definitely made a difference in your mind.That resistor just discharges the cap when power is removed.If you want to up the voltage just add more windings to the secondary of the transformer or add a voltage multiplier consisting of capacitors and diodes.
If it was in parallel with the capacitor then yes, it's a bleeder resistor, a safety feature to prevent shock as you say. The improvement seen here is because removing the bleeder stops charge permanently leaking away, at the expense of safety! A better method would be to change the switching so that when off, a bleeder resistor is across the capacitor. When on, the bleeder is switched out and the full charge is available.
I bought this same zapper from Harbor Freight today and tested it before I made any mods. The grid holds power and makes a big spark even after the button is released and I touch a screwdriver across the grid. After clipping the resistor in mine the spark is about 3 times bigger and a lot louder like in this video so there is definitely a difference. I bought the Zapmaster from Walmart yesterday and even after making the mod it's a wimp compared to this HF model
You sound excited, are as excited as I think you are? Dude, have your tools on hand prior to filming maybe focus your cam a bit too? Lol. Thanks for info though. Exactly what I needed. Cheers
Just did this mod and it does work. This zapper has a tendency to only stun flies, with this mod it makes a lot louder zapping sound and it definitely kills them.
well it does allow a bigger charge, take out the old one and solder one with more farad and higher voltage, and then maybe also use another kinda battery like 9v, but be sure your transistor and transformer can handle higher voltage/current, because else your transistor gets really hot
This video is old I know but a few things to point out that may have been mentioned before. 1. the zapper is only 600V because the main charge capacitor is just over 600V 2. that is the bleeder resistor it stops to from accidentally electrocuting yourself a month from now from it still being charged. 3. to actually increase the voltage you can input a higher voltage then the two batteries but it may very well burn out the capacitor and other electronic parts 4. the best way to increase the power is add more capacitors in parallel of at least 600v if less then they will short out and not work.
Capacitor in parallel would just increase their current lasting capacity... I would say higher voltage caps would be nice because higher voltage higher current ;D Despite lasting less the zap would be stronger with higher current ;D Only works if we raise the input voltage, the batteries. Otherwise, caps in parallel are fine but make the charging time longer when you press the button
What also works well is if you get a microwave capacitor granted it abit big but if you wire that to the wires going to the racket you will get a bigger charge.. :D
My racket stays charged for a few seconds after you release the button. I once made the mistake of setting it down by the business end and I accidentally squeezed the mesh together. A quick tap is nothing, but touch those mesh for any length of time and you get a pretty good jolt.
You shouldn't remove that resistor, it's a bleeder resistor (empties the capacitor when not in use). Instead what you could do is replace that resistor with a bigger resistor, and thus the capacitor will dissipate it's energy slower.
Im sorry bur your mistaken sir. THe reason that resistor is there is so as soon as you let go off the power/ zap switch the capaciator gets discharged. When you cut it, after you let go of the switch, the capaciator will stay charged and if you happen to touch the wires, you will get zapped. Has nothing really to do with increasing the power.
Its not quite that simple. Rather, in the name of cheapness, the bleed resistor is constantly inline and pulling down the voltage of the boost circuit. the circuit will never reach its maximum voltage. I performed this mod on a basic single thickness racket (probably the most dangerous), and the higher voltage works better on small insects (such as gnats) that normally escape through the mesh.
can this curcuit take 12v as a power source??? and how can i make where the electrodes shock in the rain and have a charge but when i turn it off it doesnt have any charge at all on the electrodes well in this case the capacitor????????? please anyone!!! this will help a lot..
what the mod like this, that is the discharge resistor dude. if wan more power try put more capacitor on it that make the sound like firework dude. i has try it .
Faulty logic, change the capacitor instead. You don't even know what the resistor does. A finger nail clipper? There are these things at stores called, "TOOLS".

Nice little mod there. I will put in my zapper an 3.7V Li-Ion battery which should increase the power a bit.
Upon test with a meter it does increase the output voltage and there is no increase in amps/watts which are the danger in electricity.

Electrohacker45 was right, this is called a bleeder resistor and only purpose is to bleed the capacitor charge off when not in use.
I've also heard you can wire a 9v for the power instead of the 3v it's running on now. Ups the power even more.
I did install a 9v battery on one and it worked great for 2 days before it burned the circuit board.

Well don't YOU have all the power in the world. Denying someone a thumbs up sure is badass.
Also if you change the capacitor to a higher voltage but a low micro number you can get a better charge...
Just did this to my zapper and it seems more sensitive and sparks easier

I thumbed up cause it was funny
This also works for the bugkwikzap rackets too, right?
so i watched almost 2mins of you trying to use a nail clipper to cut out the resistor. lol
Nice vid, but man, you should get a better camera, better lighting and a side-cutter!!

Your killing me!
Well shit homie, get rid of the rotten banannas! Good bye fruit flies. Not surprised at your mother situation either. Geez us
Is the resister the brownish thing?
I put a 400v 120uf resistor on the end and the sparks are huuge
It's also 10x more dangerous if you touched it.
By pulsing the 9 volt Dc through a step up transformer.
can this curcuit take 12v as a power source???
and how can i make where the electrodes shock in the rain and have a charge but when i turn it off it doesnt have any charge at all on the electrodes well in this case the capacitor????????? please anyone!!! this will help a lot..
1.38 thats what he says to his wife
how do you do that???
put more capacitors :3 do not cut that safety discharge resistor T_T
What? U can't believe how small a resistor for a 3v bug zapoerm was,? C'mon were u expecting a hot dog sized one? For the love of Tesla man!
what the mod like this, that is the discharge resistor dude. if wan more power try put more capacitor on it that make the sound like firework dude. i has try it .
really thicht in here meh!
wabble it till it comes off
can some body provide circuit diagram
what i dont understand is how a 9 volt battery puts out 1500 volts? lol
Ever heard of stun guns?
Dang!!!!! I am not touching that thing
dude just take the board out and desolder it
Never tried it before? This was done years ago and you waffle too much.
thumbs up if you had balls to touch it with the light on
LOL
Faulty logic, change the capacitor instead. You don't even know what the resistor does. A finger nail clipper? There are these things at stores called, "TOOLS".
learn to focus the camera
Thumbs down because you used toe nail clippers as a tool.
