Stun gun

[Kdogg]

My dad is throwing away an old tv. I am fairly new with hv parts. I am planning on searching on how to make a stun gun, telsa coil, Coil gun. Or somthing along that line, for a small project. Anyways, what can I take out of the tv for parts? Like what does it look like. Im thinking of taking the thing that converts energy to make it more powerful. I dont even know what its called. Capicitor maybe? Anyways, I have also heard you can get them from cameras.

Find the big red wire on top of the CRT...now ground yourself. http://theforum.virtualave.net/ubb/smilies/biggrin.gif

CRT's, especially a color tube, can hold a charge somewhere near 25kV IIRC. If you have to ask whats in them to salvage, then you shouldn't be messing around in them with a solder gun and some de-solder braid.

Kdogg, that red wire and ground yourself thing...well, um, don't do it...you could die.

CRT's act like LARGE capacitors. People have been killed/maimed/injured even after the TV's have been sitting for several years.

Oh no its a good idea!! I make a good ground. Especially when welding a finger back on.

I am just kidding. I assumed he meant find a ground & ground it. Not alligator clip it to my ear.

Here is an interesting link to a high voltage page.
The making of HV caps for tesla transformers seems to be new.

Speaking of grounding HV...

Here's a high dude climbing an electrictal pole for whatever reason high people climb electrical poles:

Note the cable "snaking".

i think the camera flashes capacitor will do the trick.. i got stunned when i was fooling around with my digital camera when the batteries were still in

anyone have the plans for a extremely basic stunner? im pretty new with electricity but i took apart a stun gun and it has a couple resisters, a mini yellow transformer, a diode, a transmitter, lamp, and 350V 22uf capacitor? is there any way i can reconstruct something simular without the resisters diodes and transformer? (these are the contents of a muscleman stun pen)

hope any one can help

22uF? That'll be putting out 1.3J per bang! Are you sure it isn't 2.2uF?

Actually, although you'll never get them to admit this, the pictures above show the first test firing of the LAPDs new SUPER-TASER. The "snaking cable" is actually the wire from the TASER cannon.

SPECS:

500 amps @ 10,000 volts, 60Hz cycle

250 meter range

Instant suspect incen..uhm..incapacitation. ;)

As you can you see, the SUPER-TASER has effective "knockdown" against even meth amped suspects.

Available only to JBT agencies or Forum members through my on-line webstore.

BTW, the suspect lived, though rather well burnt.

And bust the CRT tube with a brick! Not only is it fun, but it's safe too. Removes nasty static shock. :)

You kinda need all the bits. The DC from the battery is converted to AC, it then goes through the transformer, then it's rectified by the diodes and stored in the capacitor untill it's discharged through the final stage windings.

This kinda explains it:

Thanks for the link :-) I think he's wrong when he says 4 diodes are used in series. This would simply be a half wave rectifier, and there would be no point in having 4 diodes (it's easy enough to purchase a single diode that would handle this kind of voltage/current).

It's almost certainly a bridge rectifier. A half wave would simply discard the bottom half of the waveform; the circuit would take twice the time to charge up the cap. And he's got the diodes the wrong way around for any kind of rectification.

I have a more complicated circuit on my site, which uses an SCR instead of a spark gap. The advantage of this is that it will never wear out.

thanks anthony
yah im pretty sure its 22uf.. you know.. one of em teeny baterly looking capacitors (capasitence or electroylic type or whatever lol.. (still begineer))

does it have to be a spacific type of diode? the one in the stunpen was a small black resister sized diode with one silver line at one side.. can i get any diode that looks like this to make the circuit? thanks
