How to make a COILGUN!

Warning: if you screw up with this you could electricute yourself.

(sorry no plasma)

Step 2: The coil

use the screwdriver to jam the ferrothing out
stick a straw through the new hole
if the straw doesn't fit uncoil the wire and wrap it around the straw

Step 3: Set it up

use alligator clips to clip the leads from the capacitor bank to the coil ends
put a brad (ferrous) into the straw near the coil
charge the bank (the more capacitors the larger the charge time mine has 7 capacitors and take 5 minutes to charge)
flip the switch and fire

I have tried to make powerful coil guns in the past but all that happened is that I electrocuted myself and the other two people who were stupid enough to try to pull me off. I almost didn't survive, and I was wondering if you had some tips.
Tips? ISOLATION is the key.
Don't leave the coils out there, wear shoes with rubber sole, stand on a carpet.
hy plz tell me the rating of capacitor...:)

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.
i feel your pain, my mom hates all electronic that i build
yup me too
me three
Me 4.
Me 5. What is with moms and high voltage electronics that shoot stuff? :P
Me 6
Me 7
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..
Yeah,my mom don't like shocking devices...
Mine neither.
We boys on ibles are all alike!Hehe.
anything with a chance of getting hurt is looked down upon by my mom.
yep same here
normally it's the same with me
lol same here she still doesnt know about my disposable camera tazer :p
I took apart her car and built a tank. She laughed for 2 hours straight. i still have it. it shoots 2 fet in diameter sharpened iron blocks about 150 feet, using a coil gun and 20 car batteries. She buys me the iron.
i made one at school and got caught
Yikes. What happened to you? If you are so inclined.
About a month ago i put two pieces of tinfoil behind my door handle connected up to two a tv capacitors so my annoying cousin wouldnt come in but instead my mom came to give me my bed sheets and got a huge shock, it was pretty funny at the time but then she took all the electronics out of my room and locked them in a cabinet so im only allowed to use them if my dads around and he knows exactly what im doing. At least i know how to pick locks... :)
Lol
my mom dont realy hates all the electric stuff I do...since I have made some usefull stuff here for her... but she does hate anything that explodes...and I LOVE those stuff...XD
my mom doesn't care as long i do not shoot others LOOOL.
Dude, I just desoldered a cap from a TV and it was the size of my fist. No joke!
a cap from a tv... right... dunno what that is...:D
A cap stands for capacitor, It stores voltage, the ones in TVs can store up to several hundred volts in one charge. The coil gun operates on a few smaller ones but this one...need I say more? XDXD
ah right... LOL, i fail once again.... i had a capcacitor from acomputer from the (electrical :D) stone-age it was like... huge... andit exploded..........
Yeah. Discharge them backwards and they go off like a frag grenade.
yeah, i was glad i had protection... GO SAFETY! btw diddu alrdy make anairrifle once? really cool, just finished mine!
Of course.
Mine leaves a dent in an aluminum sheet .080 thick
i used a huge airtank and a long tube for barrel of 4,5 millimeters itshot trough a plank of 2,5 cm at ease! yay
ohh! awesome im gonna go get a few disposable cameras and try that.. imstupid enough to do it plz dont try to stop me =D
wow nice
Or rather, our moms.
Yeah, my class hears the word electricity and they just cower in fear.
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
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
