This surplus junk catalog ...this isn't paper, it's some kind of metal!
:)
One of the surplus outlets currently has fifty farad "super caps," but for that value I they're probably ultracapacitors. What comes next after "Ultra?" Hyper? Better quick buy that domain. Oops, too late.
But ...is $1.75 actually a surplus price? Haven't those things come down that far yet?
