The Bobbin is just a Plastic Core to Wind the wire on, to make this High Voltage Transformer.
And it is NOT Easy to make these transformers.
They consist of a Primary Winding of a relatively small number of turns of wire (22 AWG) and a Secondary Winding of Several THOUSAND Turns of Very Small Wire (40 AWG). Than after the transformer is wound, it Needs to be Vacuum Potted in Epoxy Resin, to prevent the High Voltage from Arcing and shorting it out.
I Doubt you can make this transformer.
And Sorry but I ONLY make these for my personal use.

Hi Nostro, where are you from? Do you really need this for selfdefence, or you want just repair it? in other words, do you need real stunning effect, or just visual (to defend against animals, propably)? Many years ago, i also came to this site, and asked the same question as you Well, it's not as simple as it seems. T2 is not just hard to make, as Gary has already said, but also, for real STUN effect it should be properly calculated and made very precisely. In classic stun gun design (like in your device) T2 is a key component which defines waveform shape of output pulses. Making it just by guess will result, in the best case, just in nicely looking sparks, with no real effectiveness against human attacker. I can provide information about making really effective T2, if you believe you have enough resources & motivation to make it. You will also need to re-design entire schematic, because this crap on you photo, powered by 9v battery, is totally useless.

Hi lamazoid im from mexico, i want it for selfdefence this device was a good weapon used in the LA by LAPD no is a toy i can make most everything in this work but, i dont understand this component yet, the only people that can explain how it works is you, some russians, and phillipines guys, no one of the people listed here knows how to explain it, gary lecomte say "and sorry but i only make these for my personal use" i dont want you to make this :v... i only ask for basic instructions of how works and how i can make it. elektroshoker.org/_fr/0/4209683.jpg like this but in english haha... or this one elektroshoker.ucoz.net/_nw/0/s49995783.jpg this one only have 3 wires i need 2 in and 2 out or this 3 wired can works for me too? thanks

It Doesn't matter if it is finished with 3 or 4 wires. There is a Primary Winding, it has 2 wire. And a Secondary Winding, It also has 2 Wires. But sometimes, one of primary wires is joined to one of the Secondary wires, Resulting in only 3 wires. And this Joined wire, Goes to both the input and output. IF your English was OK, I could phone you and explain this better. Mexico is a Free Phone Call for me. Here is a Brief description on winding this transformer: chemelec.com/Projects/Stun-Gun-1/T2-1.jpgFirst, you need a Suitable FERRITE CORE. And After it is Wound, it MUST be VACUUM POTTED in a Epoxy Resin. But before you do anything, you should Trace out the Schematic of this stun gun.

I believe the "internet archive" (www.archive.org) still keeps original article, which was located at steelrats.org/readarticle.php?article_id=119I can't check if that works, because access to www.archive.org is banned in Russia

I found some information in the archive.org, all is un russian and i cant read it correctly I cant found that id 119 in the forum do you can make me a new DIY guide for T2? like the one you make in steelrats?

I can provide detailed instructions here, if Gary would not mind He does not like weapon plans on this forum.

Lamazoid, OK, if you want to.
Also NOTE: I now have Free Long Distance calling to Russia, should you want to talk sometime.

thanks a lot if you can provide some detailed information about this T2 transformer, and if you can traduce this into english or give some detailed diagrams like this one elektroshoker.org/_fr/0/4209683.jpg

The number of turns, arrangement of layers, type of insulation, wire type and gauge - all of this is VERY important for the end result. Any slight variation in any of these things will result in upredictable performance affect. In other words, output pulse width, amplitude and shape will be altered, so as the efficiency against human target. In ideal case, you need the oscilloscope and special 1000 ohm load to check pulse params. But if you don't have it (which seems to be the case) follow the instructions _VERY CAREFULLY_ The following picture shows proper pulse: voltage divider is 1:50, so amplitude is about 1500V under 1000ohm load, and width is about 70-80 uS. Most commercial "stun guns" (so called) have much shorter pulses with much higher amplitude, and usually sinusoidal form. The one you got is not an exception. Many practical tests against bio-targets (mostly pigs and human volunteers), conducted over years in Russia, shows that this causes only PAIN effect. Only certain pulse width and amplitude (say, "not less than..") can cause real muscle incapacitation effect. For further explanations, lets say that pulses above 1500V amplitude and above 50uS width are considered "effective". Modern Taser models, like X26, X2 also use this strategy, having about 100 uS pulse width 1200V amplitude, at low frequency (pulse repetition rate) of just 19Hz. But Tasers are affective only while trigger is pulled (current flows), after that target is able to struggle and counter-attack immediately. Russian experience proves that HIGH frequency (100Hz and above) is the third key parameter to real incapacitation, just like you see in the movies So, again: effective pulses (properly made T2) and high repetition rate.

But let's continue with T2 itself. Except mentioned ferrite rod and insulation, you will need two wire sizes : 0.112 and 0.63mm. Russian standart specifies wire diameter in milimeters, while American uses numbered wire gauges. To convert one into another you can google "AWG table". And another _REQUIRED_ thing is vacuum potting chamber. Don't even start without it. So let's assume you have all the things, a lot of patience and straight hands First, wind the secondary with 0.112mm wire. (37 AWG) First layer has 160 turns, and it starts 15mm from the end of core (as shown on the pics above). Followng 9 layers have 260-270 turns each, and last layer has required amount of turns to get total of 2600. Winding width (wire layer width) is 36mm. Eeach wire layer in insulated with single layer of Teflon tape, with 8-10mm overlap. Pics: regular wire layer, interlayer insulation, and last layer.

After secondary is wound, insulate it with 3 layers of Teflon tape. Then comes the most tricky thing (my personal invention) which provides effective pulse. Follow instuction _VERY CAREFULLY_ Take 0.63mm wire (22 AWG) and wind first layer of 28 turns, centered. fix it with super glue (cyanoacrylate). The following layers are 26, 24, 18 and 12 turns, all _CENTERED_. Total 108 turns, sacred number You should get something like this:
