Just as I was about to drop an old 120MB hard drive into the hopper, I
remembered that HD motors have big, powerful magnets. Since one can never have
too many magnets, I went diving for them. I temporarily forgot about magnets
when I spied the motor windings: lots and lots of beauteous magnet wire! OK,
we'll save *that*.

The next item destined for the landfill was a large PCB that came out of .... I
forget... maybe a commercial piece of exercise equipment (StairMaster?). I'd
never noticed the 10 or 15 tiny toroids before then. The PCB stays!

Tonight I'll strip a "new" toroid, wind it with "new" magnet wire (a la
bifillar), and see what that puppy does with a white LED.

It appears that he not only has a life, but he also has a hobby that
he enjoys. Thanks for playing, and don't try again.
