Fastidious readers stop here.
I needed a 1 inch thick rough-surfaced spacer for the
bottom of a water drain pan. I have way too much old
computer detritus.
An decades-old 2GB SCA-interface hard drive from a
long-ago-recycled Sparcstation 20 is just the right
size. I glued it to the bottom of the pan, circuit
board facing up.
If there is any confidential data left on the drive
(which I cannot read but the Bad Guys might), water
immersion won't improve readability.
The tantalum capacitors on the board no problem;
they won't be heated above boiling, and tantalum
pentoxide does not react exothermically with water
or air.
What old electronics should I abuse next? In junior
high, I blew up low value resistors in switched wall
sockets (10 ohms makes a wonderful flash and bang),
but I've learned better uses for those.
