• What's inside a stun gun
Today, let's see what's inside a high voltage module of a stun gun. Let's reverse engineer its schematic and explain how does it work. The module was in some kind of epoxy resin, so I had to test various ways to remove the resin.

Beautiful water cup. Even plugs into the wall and can heat water directly.
I admire you had patiency to slowly remove the resin. I definitely wouldn't have it.

I wouldn't either. I would forcibly chip it off with cutters. There must be a stronger chemical that can dissolve it quickly.

Great job in taking the resin apart and back engineering the device internal workings.
Thank you very much I think you are the only one who can reverse engeniring almost everything Nice work
Last time I tried to take apart some resin like this, baking it worked quite well, it became soft AND cracked in many places. I think it depends however. If there is a lot of unreacted chemicals in the resin from the manufacture, this probably works well. I didnt use a normal oven though, instead I used a 400W mercury vapor lamp with the UV protection envelope removed and a reflector. This was heating and irradiating the resin a lot with IR, visible light, lots of UV-B and a bit of UV-C. The wooden table also became black at the surface from all the heat. I always heated it, then peeled off some chunks that became soft, then re-heated and so on, until eventually the last bits were completely dry and hard again. But by that time almost everything was removed. The electronics were relatively undamaged and I was even able to read off some values and the markings on a PCB inside.

Wow that is crazy. I will check out your channel because I believe I will love it..
Just a quick safety tip: always put the sodium hydroxide in the water, and never the other way around. To understand why, try to visualize in slow motion the first drop of water that would touch the sodium hydroxide, it would be a microscopic quantity of water in contact with a big amount of sodium hydroxide, thus it would be highly concentrated and could react violently. The other way around, the first flake of lye in contact in water would be dissolved in a "massive" quantity of water. My dad decided one day to put the sodium hydroxide flakes directly in the drain and then pour boiling water on it, it made a geyser and his slippers still bear the traces of this experience.

You can mesure that résistance with an isolation tester or try to mesure à portion of it and deduce its value., it like the potentiometer found in old tv focus .
Do you want to soften the resin or do you want to make it more brittle? I would think if you make it harder but also weaker, then you can easily just break it off with impact soft enough to leave the electronics intact.
Wondering what could dissolve the potting on some blob IC's. (acid excluded)

may be because voltage in its natural form occurs in dc form .the 50 hz ac we receive at home is because it easy to send current in ac form without much losses while dc current heats up the element due to heat loss ...secondly we need some circuit/mechanical mounting to produce ac oscillations no such thing in batteries . sinusoidal/ac waves can be produce from battery using proper ckt . where sinusoidal wave oscillate between - and + pf battery

Can you or someone explain the direction of conventional current flow in the auxiliary winding at 11:26 please. You said the voltage built up supplies even more current to the base of the transistor, via the diode and 24ohm resistor.....so is conventional current flowing from the bottom of the winding, to the top dot, towards the base, out the emitter, and down to the negative rail? It's just confusing because the polarity is marked the same as the primary winding, which made me assume it would be moving from the dot, to the bottom of the winding. Many thanks.
@Mark1024MAK

The primary is “consuming” current, but the auxiliary is generating current. So it flows into the dot (positive) end of the primary. But flows out of the dot end of the auxiliary winding. And yes it flows as you described it, going from the auxiliary winding, through the base-emitter junction, to the negative rail then through the diode, through the 24R resistor and back to the auxiliary winding.
u speak so nice,it sound like u r singing
1:35 you shouldn't mix sodium hydroxide with warm water. The reaction is exothermic and it produces heat when mixed with water. The warning lable says so too.

if you like this HOBBY books will not help much, they are often too theorical, but you can try to find some entry level "collection" of electronics courses on like basic components, transistors, logic and analog chips and the ususal audio amplifiers and radio stuff, school\university books are no good or maybe they'll help you later... also the internet is a good place to learn a lot of things but websites and makers are often too much self promotional and little explanatory
