easy, steal a flash bulb from a disposable, solder it in :D
should be able to get a used disposable for free if you ask nicely. say it's for a project.
and make sure it's the bulb that's blown. the bulb is just a tube filled with xenon. there's no filament like an incandescent.
fc is like an ethernet network but of hard drives. for example, you can have a fc switch and hook up lots of drives onto the switch, then ano computer with a fc card can connect to the network and use any drive
look up iscsi, it's allows block level access to a device over an ethernet network...
use flux when you solder, it helps the solder flow
that's definitely an electrolytic cap
not only electrolytics are polarized, tantalums are polarized too
