I have a very nice cordless drill with a dead NiCAD Pack.  The mfg
wants $50 for the 10 cell pack.  Sub-Cs delivered mail order to
replace these would probaly run ~$30+.  Based on what I see on the
capacity of the NiCad Sub Cs, the AA NiMH have surpassed them and are

I'm looking for a video, hopefuly a slow motion one, that
shows a CRT imploding. I'm having no luck searching Google.

I've got a 27inch XBR, cicra 1991.  Sound and picture still
great.  However, in the last couple of days, it's acting very weird
