Hmmm, and I thought I was the only one that did that kind of thing :-)

There was no mention of ICs, so I thought I'd throw in my 2c

Back in high school I built the model CS-1 Chip Sacrificer:
It consists of an AC line cord, a double pole double throw knife switch
with lots of exposed metal, and two pieces of solid 12 gauge copper wire
that are spaced about 0.3 inches apart.
The IC is slid inbetween the two rails and forms the "load".

DO NOT BUILD THIS DEVICE, IT IS DANGEROUS!

Well, with that out of the way, here's how the CS-1 was used:
Find an IC that caused you lots of grief, preferrably something that
you spent a lot of time finding and extracting from a piece of equipment.
Slide the IC in between the rails, pins 1,2,3,4,5,6, and 7 on one rail,
pins 8,9,10,11,12,13, and 14 on the other rail (14 pin dip).
Open the knife switch, Plug the CS-1 into a source of 110VAC.
Close the switch, being careful not to touch the hot leads.

DO NOT OPERATE THIS DEVICE, IT IS DANGEROUS!

If you get a good chip in an epoxy case, you will be rewarded with
a resounding FFFFFFFFZZZZZZZZZZZZZZZZZZZZAAAAAP, a cloud of toxic black
smoke, and a 360 degree shower of flaming silicon.
The less exciting sacrifices just go Pop!

DO NOT SACRIFICE IC's INDOORS, A FIRE HAZARD EXISTS!

The procedure is best performed near the repaired gear as a warning
to the other ICs not to fail :-)
