This is probably one of the easiest Arc Reactors to make at home. it cost me about $15 and took about 30 minutes to build. It is made to look good under your shirt (sorry I couldnt get any pictures of me wearing it). it should look like the MVKI or MVKII
Step 1: Materials
Here is a list of materials:
($8) LED tap light
($3) set of shower curtain rings
(20 cents) conduit locknut
($2) copper wire
hot glue gun
Step 2: Take Apart the Tap Light
this is relatively easy...
take off the back of your tap light.
You will have to get the top off. to do this you will either have to unscrew the three small screws or wedge it open with a knife or srew driver. then cut off the edge of the circle part to make it look like the picture
Step 3: Make the Plasma Ring
center the conduit locknut in the shower ring and wrap the wire around the conduit and the ring between the cogs. it should look like this
Step 4: Finishing Up
All you gotta do is hot glue the belt to the battery pack (do NOT glue on the batteries) and glue the ring to the top.
