Wow. I just learned more from you in a few short minutes more than I have in a loooong time. Your willingness to explain what the symbols in your circuit diagram actually meant, triggered one of those "holy crap I get it" moments. Some people suck at teaching, some do not. You definitely don't suck. Great job.
Underrated is an understatement. You rock, sir. Not to disrespect anyone, but I had just watched some 40 min of video about Joule thieves and a bug zapper from other youtubers, and I was completely confused. Then I watched your 8 min video and everything makes perfect sense.
Guys like you amaze me. I worked in radio for many years and got friendly with a lot of techs and the best bit of advice I ever got when I was asking a lot of questions was, "You don't have to know how it works quite often, but you have to know it's NOT working." He was talking of IC's and the like. Classic answer I thought.
Thank you for explaining how the circuit works. I use your explanation as the main basic template as to how other charging circuits in other electric rackets work. Their circuits are almost the same as your circuit except that a few components get switched or shuffled around. For example, you might get a voltage doubler that's included to charge the center tapped primary coil of the transformer. Anyway, I just wanted to say thank you and to say that you would make one heck of a great engineer !
This almost made me feel like I was back in my ET phase of US Navy Gunner's Mate A School back in the day. I remember hooking up very similar circuits to the metal stools, aka Butt Zappers, we sat on in class :)
Please correct me if this is wrong, but I think there's a small step just before the field collapsing - when the inductor current (current in the right hand side of the transformer) reaches it's maximum value, the field strength becomes constant, which means the induced voltage in the left hand side of the transformer drops to zero, which in turn causes the NPN to switch off. Now the collector will not pass current and the field in the right hand side of the transformer collapses.Good vid thanks
Wow, this was perfect. Thank you! Most times even the most "simple" explanations I've found on line are above my skill set. This fit perfectly in my wheelhouse of expected knowledge and easy to follow new information. One request. When you draw schematics like you did (thank you!), can you give us a little legend for what each symbol is?
+Proto G Yeah, I noticed that and I appreciated that. I became worried that you are going to burn yourself out repeating the same concepts so the beginners can follow. Imagine having to explain what a transistor does in each episode. If you don't repeat the information you'll loose the fantastic beginners guide feel you have in this video. I actually have an idea that would keep the repetition down, while keeping beginners informed, I'll PM you about it.
+Scott Cress Thank you so much! I got your message and that's a really good idea. I've already started filming some other videos on my list so in the mean time I will try to keep all of the videos in this series aimed at beginners.
Your ability to teach is amazing! I came here to learn about the bug zapper and ended up learning way more ....almost to the point that I forgot all about the bug zapper, lol. I do have a question I was hoping you or someone could help answer: • 7:03 I understand the purpose of the bleed resistor, but doesn't that also mean it will constantly be trying to drain the capacitor, thus making it inefficient?
Great explanation! A ghoulish proposal: It would be a fun project to add a counter that keeps track of the total number of insects zapped. A tiny Scub1000 LCD counter module and the appropriate conditioning circuit could watch for voltage drops across the bleed resistor (or perhaps current spikes through the output capacitor) and increment the counter's display. A problem might be false counts caused by sizzling corpses but the conditioning circuit could maybe distinguish between sizzle and pop. The Scub1000 is so small it could easily be fitted into the handle along with the additional components. Unfortunately, my circuit-designing abilities are insufficient to actually figure out the details but I do have the ability to follow a schematic and build it in. Does anyone have any circuit suggestions or thoughts on this?
+Chris Uroda I can't reply to your comment. You may need to change your settings. The voltage in the left side of the transformer drops below the turn on voltage of the resistor as a result of the right field collapsing. Remember, the battery can slightly open the collector on its own so the collapsing right field needs to act against that base voltage to turn the transistor completely off. Once the right side of the transformer reaches its saturation point, the collector begins to close because it is back to only having the battery voltage. In this circuit, the collector rises to completely on and falls to completely off similar to a sine wave.
Can a single battery create more voltage? 3000? 4000? Just by adding more turns to the coils? You may have figured out that I am not an electrical engineer? I am working on a project (prototype) and am doing things I have no business doing based off of my intellect level. Also, if you left the zapper ON, would it drain the battery very quickly, or only gradually unless it is being activated by closing the circuit due to a bug touching 2 wires?
Very well done video. great picture and explanation. It might be helpful in the future if you discuss a little about the value of the components. like, if you raise the value of this resistor, then XXX will happen, or this capacitor requires a max voltage value of xxx in order to ...... I found your video to be clear, concise and informative. thanks
That's so cool! Just one question: why doesn't the battery gets instantly consumed when we use the bug zapper? Is it some special battery with a really large amount of charge in it?
+photo g Ok ive blown up mine just by swapping the 3v to 9v. would like to make my own 3v so can you let me know a typical transistor that would work? also i think the transistor is the limiting component in raising the voltage and current here-is there a transistor you know could handle a 9v battery proto g?
One question I have is this. At about 5 min, you say the field is no longer changing and it collapses. Why does it collapse? Does it not jsut reach a steady state where current flows through the first coil to keep the transistor on and current flows through the second coil down to ground?
Sir well stated, thank you. I have a question, in order to remove the bleed off effect, would bypassing the bleed resistor to the job? and by doing so would this cause any negative effects, such as discharging the battery, or over loading any components?
Hi, very instructional and well organized video! I have two questions. Could the electric circuit inside the zapper be considered one LC Tank Self-sustained oscillator of the Hartley type? Also, what would the connection be in order to see on an oscilloscope screen the output alternating voltage of this circuit? Thanks for your attention to this. Cheers!
thanks for the technical desription on the circuit of a fly zapper. :) I am going to build one for the purpose of destroying European Wasps which are quite an issue here! Cheers! Mick
Proto G thanks for the detailed video of these as I have one with a circuit that has no power meaning it doesn't zap but the red power LED is on. when I stick something metal across the grids it makes a tiny zap and on another zapper it makes a loud zap. Any ideas? Bad transistor? I have the circuit and am not sure if I can fix the zapper. I'd actually like to turn it into a curly CFL bulb driver b/c I saw a video on here where someone did just that.
Good show brother question i have a garden with small animals everywhere eating it could i run wire around it the garden tie it into a zapper to keep things out and how far could the Zapper be effective
Awesome and simple video. But I'm a NOOB so, can you explain how the DC battery makes the transformer work [transformers only work with AC, right?], don't you need a chopper, to feed the transformer some variable electricity? If so, where is the chopper in this fly swatter? What does it look like? Thank you kindly
Was looking at converting one of these to wire a plank to shock a cunning rat into a bucket of water. I have failed to catch with traps, cages and electric kill trap as it is too smart to enter any. Once bitten, twice shy. You mention the bleed resistor to drain the capacitor, so is there any issues with replacing the switch or just simply taping it down so it is on for a longer period (overnight)? Or is it better to remove the bleed resistor? I am hoping the first option as it would provide multiple chances at getting other rats. Cheers.
I swapped out the AA batteries for an 18650, which gave it a little more power. I also added a TP4056 charging circuit. But that's just until I receive the 400,000 V high voltage generator that I ordered to replace the circuit that came in it. That should be interesting lol. I know they highly exaggerate those numbers, but I figure it'll probably be putting out 20-30kv 😁😜
so the joule thief part of the circuit is not so that a 1.5 battery can be used in the case of an led it is to make a simple oscillator? why is this used instead of using a 2 transistor typical oscillator circuit?
Excellent tutorial, Question for you. I have a fence charger that runs on a 6 volt battery. Once the battery died I replaced the 6 volt battery to 9 volt battery and now it won't work. I know I fried something on that circuit. What could it be, is that an easy fix? please help.
Can I build one that is windowsized , because every year some garbage cans outside attract flies and when they get in to my house there is a certain window that allways seems to attract them, like 95% of bugs go to that window, and the other 5 I miss when hunting also fly over there, so if I have a permanent zapper, that is as big as the window there is no way they will miss it, it would save me a lot of bughunts
My question: Does this actually mean 1300V DC seeing as how the diode technically converts AC to DC by only allowing the current to flow one way? Or is this HALF AC seeing as how it's only allowing positive bumps which (come to think of it) would act as a switch to turn the flow on/off depending on where the peak of the bump would be? Like it'll still be DC just because there's a diode acting as a check valve, but it's not straight DC because it's not a straight line, but rather bumps, which would in turn make the Diode act as a switch. I maybe overthinking things a bit with this, but I'm trying to understand what I'm dealing with here.
Nice video!! How is it called the first type of transformer? For me it's a little weird that kind of configuration due that they are sharing the same node next to the switch, so they are electrically connected. Thank you so much for your explanation!
You know you are in presence of a truly Mad Scientists when he wear gloves even to draw the schematics XD Could we send you things for you to explain, like cheap Chinese electronics from aliexpress to see how they work and if they are any good?
+Josuel Servin I am definitely open to suggestions. I am mostly looking for products with through-hole boards because they are easier to visually explain. Once I get around to setting up a P.O. box, I will start accepting mail. Thanks for watching!
Understand very well.thank u so much. Make this type of other ckt and an analysis that b'cause i understand and I like this type of video.for sharing knowledge to others. Best of luck for ur future
I have a bug zapper I modified a while back and added several more capacitors on them. Since its non polarized foil caps (I think they are like 400v by factory default) can I add a electrolytic 400v cap since there's a diode? If not should I rectify the ac with 1 diode or a chain of 4 for full wave 120hz dc
+The Computer Tech Guy Yes, you can add an electrolytic that is properly rated for the output from the transformer. Using a full bridge rectifier will result in the capacitor charging about twice as fast. Removing the bleed resistor will increase your output as well but it will be more dangerous to handle.
Great video and great explanation! Can you explain how removing the bleed resistor would make it more powerful? A guy had a mod video showing people how to disable the bleed resistor. He was chastised by so many people in his video comments section on how it wouldn't do anything to make it more powerful. The best way I've seen is by adding a stronger, external capacitor wired/soldered on to the existing capacitor. I saw a guy add a small, rectangular shaped capacitor salvaged from a broken grinder to a bug zapper swatter and it seemed to be stronger. My reason for modifying my zapper (which uses 2 "D" size cells) is to kill the yellow jacket bees that try (and sometimes succeed) to attack my toddlers at almost all city/county playgrounds that I take them to. What would be the best mods you would recommend to turn a fly zapper into a bee/hornet zapper? Also, could I replace the three screens with one piece of strong steel mesh such as galvanized steel or aluminum mesh? If so, how would I wire on all three internal wires? Sincerely, Jacob SurvivalGeek (RUclips) ruclips.net/channel/UCfRsUPToBXp4ZIre__dJg4A
Very Interesting, I'm trying to build a Bug Zapper lid for a metal Coffee can to keep gnats & other bugs out of the can of Food Scraps with aluminum Screen for a screen door & a 12 volt power source, I need the wires to get a good connection with the screen & the bug zapper to work all the time, as long as it's hooked up, without setting off the surge protector in the Jump Starter I'm using for power, since the 12 volt Lantern Battery seems to be not doing anything, I've got a negative wire & positive wire fastened to opposite sides of the lid, with a negative wire as a ground wire connecting the screen to the coffee can, How do I get this to work without setting off the surge protector?, hook wires to a capacitor, then to the screen?, I'm trying to build a bug zapper, because another bug flying around the house is the size of a speck of dust & flies right though the screen of a bug zapper, untouched.
im confuced. What type transformer used here? 3 windings are there , also primary and secondary are connected and given to supply. how is that possible. please tell me , pleaseeeee
To clarify what I understand to be the working principle, you could hypothetically convert one of these into a functional Tesla coil with a few adjustments to the wiring, couldn’t you?

That's so cool! Just one question: why doesn't the battery gets instantly consumed when we use the bug zapper? Is it some special battery with a really large amount of charge in it?

That’s more expensive than just buying it... and transformers, especially HV ones, are a PITA to wind.
what is the design criteria for that oscillator.
If I use more switching capable trasistor, can I make more voltage?

How would the output look with a two or three stage voltage multiplier added? 😉
Nice bro.it is awesome. I want to know more about transformer and what is the output voltage across the capacitor please reply me?
what if the button is pressed and locked into On position.? would it burn out the coil and resistors?
Multipurpose pen. Pen and oscilloscope probe. You can see the silver ring: it's for the ground lead.
Something is not right. 🤔 How can someone explain so nicely. U earned a subscriber.
what about your other videos like
the soldering iron???
I have a VW coil, 12v battery, points and condenser. How can I make a bug zapper out of it?
Bt transformer want ac supply ? Then how he getting ac supply? On what principle this circuit is working?
Watch the video, I explain that.
Please mention components numbers on ckt diagram
I learned something! Thanks!
+Arvid Sundqvist Thanks for watching, please like and share!
What is the output voltage of the transformer after being stepped up?
can I take the diode out so it can be more powerful and give more voltage
What is the ratio on that transformer? How much voltage comes out of it?
Go into details on the left down diagram
Proto G Thanks man
haha I think I might just wack the fly with a news paper!!
Seriously, a very good tut.
