Just curious: For those of you who have done this - did you scratch build your set up, or were you able to find some cheap battery-powered LED item whose guts you were able to fit in the cannon?

I've read the general LED tutorials and several threads I found in the Creative GD (couldn't find anything specific to this cannon (or any cannon), though... so if I missed it, please let me know!), and watched Frenzy Rumble's video tutorial, so I think I have a fairly good grasp of what needs to be done if I have to go the scratch route, but I just thought I'd see if anyone had found something that miraculously fit in the cannon with little fuss.

Thanks!
