Unusual functions of cheap parts

A 1N4007 can also be used as a drift step-recovery diode and as a
plasma avalanche diode. Together, two can generate a kilovolt edge
with a 100 ps risetime.
GAASfets make good fast analog switches; they behave pretty much like
jfets.
Wide-open LDO regulators make nice resettable fuses.
Ferrite beads do all sorts of interesting stuff.
Power mosfets make good heaters, and TO-220 bipolar transistors make
nice temperature sensors.
LVDS line receivers are surprisingly good comparators, and *fast*
I could go on...
