Introduction: How to Make a COILGUN!

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

(sorry no plasma)

Step 1: Materials

for this you will need;

capacitor bank ( https://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

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

    Get as many as you can with at least 2000uF. The more the better.

    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 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..

    haha, all moms seem to be the same way! they hate stuff when they don't understand it! My mom hates most of my electronic projects(wait til she sees the oil burner transformer I ordered) I'm going to use the transformer for a jacobs ladder. and im 13.
