## can anyone help an extreme amatuer wire a group of capacitors together?

I'm in the process of making a version of the tazor glove instructable, but I'm trying to make it more compact while still powerful.
I've 'liberated' a few capacitors from some old pc cards but I'm not sure what I need to look for to know voltage or amps or whatever it's measured in, and some don't seem to any helpful markings at all.
What I'd like to do if at all possible is wire as many capacitors as I'm able into a line that can circle the wrist, but I'm not sure how to do it or whether it would matter if the capacitors are of different sizes/powers.
If someone can help I'd be very appreciative but keep in mind I'm a true amateur so any complex lingo will probably just confuse me, if you need to know anything else I'll let you know as soon as possible.

In practical terms wiring them in parallel is easiest, but you'll need to take the voltage of the lowest rated cap to be safe. Wiring 2 identical caps in series will half there capacitance, but also half the voltage across each cap, so effectively this doubles the voltage rating of the caps when used together.

I think what you would want to do with the tazer glove is find some 400v electrolitics (Monitors and computers PSU's are a good sauce) and stick them all in parrelel. As for marking, electrolitics are the ones that look like little coke cans and should have everything clearly printed on the side, don't worry about mixing and matching as long as you pay attention to the voltages and the polarity.

Be warned however that a few joules of juice at 300v will kill you, I've used a larger flash gun charger to charge a little cap bank the size of my fist to 400v and it will blow chunks out of a screwdriver if you short it out. The energy stored in a capacitor is E=1/2CV

^{2, once you get over a few J's your going to start killing people.}See how if this were melded into 1 capacitor casing then the middle pair of plates is not really connected to anything and is just going to be subjected to the fields set up by the outer pair of plates, hence you have effectively just doubled the plate gap.

Secondly consider the equation E=1/2CV

^{2, if you double the capacitance you double the energy storage, but if you double the voltage you quadruple the energy storage. So if we doubled the voltage without halfing our capacitance then all of a sudden our pair of 1J caps could store 4J's when wired in series.}E=0.5 x C x v

^{2}or half of the capacitance times the voltage squared. for your 1000uF cap it would be

0.5*0.001*(6.3*6.3)=0.02J

if it were a 1000uf 400v cap (hypertheticaly) then

0.5*0.001*(400*400)=80J

see how voltage makes a huuuuge difference. A 1000uf / 400v cap would be about the size of your fist btw.
