So I made this arc reactor to wear under my shirt tonight:
I started by printing this thing, which took about an hour and a half on my printrbot:
Then I very quickly and dirtily soldered the forty-something connections (I was in a real hurry to make trick-or-treating). I added a potentiometer for dimming. All told, I spent under an hour frantically connecting things and getting it put together, then realized I was really late and didn't have time to clean it up, so I covered the most janky connections in hot glue.
I'm hesitant to even show this, but it's the kind of thing that some of you are going to look at and say "Holy crap, I can't believe that thing worked all night even though all those leads were stabbing you in the chest and should have been shorting out like mad", and very few of my friends read Ello yet anyway, so it's safe to show off quick ugly hacks that turned out okay here, right?
Okay, I'll peel back the curtain. Here's the wiring mess that's making it work: http://imgur.com/UdrKx69
I'm still shocked that it worked so well. There's no excuse for this working as well as it did. I'm apparently way too careful in my other electronics projects. Electrons like to flow through metal if you give them the slightest chance to do so.
