I would assume that building your own lightsaber, given it's form factor, would involve significant amount of laptop-like small, unfriendly electronics (not to mention fiddling with force fields and other advanced physics) :)
You would think, but based on the literature they don't actually seem to be that finicky. Just stick some kind of crystal in some kind of case, with a couple other off-the-shelf components, and that's it.

What has wrong with that comment?
Nothing at all. But I can't think of any other community where we'd get into a discussion of the build process of a lightsaber, can you? I love participating in such a geeky crowd, even though I was never a big Star Wars guy myself.
Reminds me of Reddit
Or reddit or RPF or 4chan or board game night or Comic Con or...
That's how Star Wars treats all of its engineering things. Just give it a kick and it starts up.
