Picture of SIMS plumbob
Two years ago my wife told me that she wanted to be a SIM for halloween.  Being the dutiful husband I am I got to work.  I researched for hours the best way to go about this project.  There were ALOT of helpful designs out there.  Unfortunately i'm kind of arrogant, so I looked at all the well thought out, well intentioned designs and thought, I can certainly do that better.  My major gripe was the materials that were being used by others.  To me, the SIM plumbob is a crystal that radiates light from the inside.  The crystal structure breaks up the light in a sparkle kind of way rather than a flat uniform color.  With this in mind I set out to create the awesomness that is before you.

Note:  There are deffinately things I would change with my design if I were to do it over.  Financial considerations played a big role in some of the steps I took.  Please feel free to critique the design.  If I decide to make another one I will take all ideas into consideration.

My SIL was a big Sims far, and we built something like this back in 2004. We used a tissue, wire, and balsa construction, which lets you support the assembly from a baseball cap, more or less. It's not as pretty, though. We also used some electronics to get our hats to fade from green to red and back; the intent was to eventually make this remote-controlled, but that part never materialized.
We wore these at BayCon 2004. Later, the SIL worked for EA doing QA for Sims, and they were a big hit there as well.
LED (and battery) technology has changed a lot since then; it would be interesting to do an improved version, especially now that Sims Social is out too. Alas, EA laid off the SIL, and the motivation isn't quite there...

Thanks for the comments. The weight was always going to be an issue with my design so I did the best I could to make it so you wouldnt have to wear it on your head. I have absolutely no experience with LED's and circuit boards but I would really like to learn it. My hope was to eventually make another one with a small motor in the middle that made the whole thing rotate, but like you, my motivation fell off after the initial wow factor.
