for this you will need;

capacitor bank ( http://www.instructables.com/id/EV2MC84ZATERXTS1L5/?ALLSTEPS follow steps 1,2 & 3)
transformer thing (you can find them on many circuits )
straw regular or coffee

tools;

scissors
screwdriver
Duct tape

What part of the capacitor bank do you attach the coils to?

You could easily make a more powerfull capacitor charger, with 1 NPN transistor, 2 resistors, 1 transformator, and 2 - 4 diodes. ;)

How do you know in wich direction the nail flies out ?
Jun 14, 2011. 6:17 PMcsparks1 says:
Use the right hand rule.
Grip the wire with your thumb pointing from positive to negative.
The direction that your fingers point in is the direction of the magnetic field.
I'm sorry for explaining that poorly; a little research on your part into the right hand rule should set you right.

LMAO take a guess and point it hope it doesnt shoot you in the face!!! Ah just kidding you usually put the ammo slightly outside the coil on the negative side. As it pulses, the field pulls the ammo first into the middle of the coil, then the field is shut off and the momentum propels it forward. Just think of it as a momentary magnet that pulls the ammunition then lets go.

would 1 transformer out of a UPS (uninterpretable power supply) it supports 2 screens and 2 modems. and surge protects 2 of anything.

all i know about its model is
Manufacturer: ULTRA
Model: RCD-UPS1500D
Item: UPS (Uninterpretable Power Supply) Battery Backup

what wires would i use to charge the capacitor on this kinds of transformer. there are 2 low gauge wires (black and red, duh thats power) but what do the other 3 on the opposite side do? they are a higher gauge wire, and when i charge my capacitors how to i charge them all at the same time, and have my voltmeter that has like 50 different other settings including capacitance. all of that hooked up at the same time. if someone can give me a link to how to do this it would be great.

my MAIN need is a label on how to hook the transformer up to the supply of power and into the capacitors to charge them. <---- that is what i want at least! please help!!!!!

what type of transformer did you use?

my mom got mad at me when i blew up on of those big lpg tank in our back yard andxdamn it was loud and left a big crator in the ward.. but it was 4th of july so it was ok no one got hurt no one got mad (just mom) ohh and wee used 3 phantom fireworks big mortars 2 blow it up and it was fun u have to try it some time!

It's a Inductor

i got a transformer out of my sisters careeoke thing that she had when she was like 10 and its got a huge transformer in it its loike 4 inches in w/h/l lol
Jan 21, 2009. 1:52 PMcowtipper97 says:
Finally finished mine! Works really good, but I'm going to add 2 more capacitors to mine for a total of 6 so it shoots faster. I showed my mom and she wasn't happy that I'm making thing that shoot projectiles =/ so I might have it much longer. Anyways nice instuctable rating 5 cause it worked when I made it.

My mom hates it but my dad thinks its cool. probably cuz he works for electric boat designing weapons systems for submarines.

i feel your pain, my mom hates all electronic that i build
Jul 26, 2010. 9:34 PMpocholox8 says:
yeah me too and my room is so messy

yup me too

Me 5. What is with moms and high voltage electronics that shoot stuff? :P

my mom let me make a tesla coil that made a few million volts of electicity. it was cool.
Jun 22, 2009. 8:35 AMcowtipper97 says:
I dunno. My mom found some schematics to the "worlds smallest shocker" that Plasmana made and asked me what it was. I just told her it was for part of the coil gun cuz she would get SO mad if she found out I made that..
Jul 3, 2009. 6:01 AMbylerfamily says:
Yeah,my mom don't like shocking devices...
Jul 7, 2009. 9:09 AMM4industries says:
Mine neither.

We boys on ibles are all alike!Hehe.
Sep 28, 2009. 12:14 PMthe_lark says:
Or rather, our moms.
Sep 28, 2009. 1:40 PMM4industries says:
Yeah, my class hears the word electricity and they just cower in fear.
Oct 11, 2009. 5:21 AMthe_lark says:
at my school they go like: wha...whaaat?.It's amazing how stupid people can be at times.Not saying i'm a genius or anything .I keep burning my self with my soldering iron that's not exactly clever :-p
Oct 3, 2010. 7:40 PMpocholox8 says:
i know right?doesen't it also feel good when they say you invented it and they ask you if you can make one for them for a price and you over price it? i hate people who think they know more about you in electronics and they think they're a genius
Oct 15, 2009. 6:38 PMcowtipper97 says:
Yup people do the same thing at my school. when i told them i got asecond degree burn from a soldering iron last week they all asked ifthat was a clothes iron.. gets kinda annoying cuz i have to explane whatit is like 4 times before they stop asking
Apr 13, 2011. 6:23 PMCyclonicNinja says:
once a friend of mine actually grabbed the hot end of the iron, not a fun day at the waiting room :(
Jan 7, 2010. 4:14 PMcdousley says:
kids at my school stuck an led to their toung to shock themselves lol
Oct 4, 2010. 11:15 AMM4industries says:
Unless they have alloy fillings in their teeth and vinegar saliva, that wouldn't work.
Oct 4, 2010. 6:28 PMcdousley says:
haha they have no idea
Oct 5, 2010. 4:19 PMM4industries says:
You'd be surprised what people think would work spectacularly or fail spectacularly just end up doing nothing unimpressively.
Oct 5, 2010. 6:43 PMcdousley says:
i know its crazy
May 9, 2011. 12:51 PMhotrod1 says:
yeah its hilarious. my class didnt know how to hook up a battery to a lightbulb
Jul 25, 2009. 3:01 PMtoogers says:
anything with a chance of getting hurt is looked down upon by my mom.
