if you got one of those shake flashlights  lying around ,  they  have a honker strong magnet  in  em ..    not to  mention  a mile or so   of pickup wire  .

speakers are great to   but can be a pain to  get the magnets out .

I started winding with magnets from dead harddrives. The bigger desktop ones have two big ones in em.

Would the voice coil of a hard drive or the wire in it be useful to make a pickup?

Magnets are cheap (free from dead hard drives, old landline telephone handset voice coils, old kids toys, etc.). Someone around here at CBN has also used whiteboard / refrigerator magnets. Magnets can also be purchased relatively cheaply off of eBay in a variety of configurations (cylindrical, circular, bar, etc.).

Staring at the magnetic walls of my office just now, I've been wondering how you might construct a p'up from 3M magnetic strips - maybe a stack 'em up into a Flatpup sort of design? Hmm.

Those shake lights look cool.  I'm going to have to rip some hard drives apart now and then look into surplus speakers I think. I may just do the math too to figure out how much a change in magnet strength impacts the output of the pup.  Another thought I got from a lawnmower repair shop was perhaps flywheels.  Interesting.....

Thanks ya'll...
