Was just in communication with a fellow who’d had his instrument stolen some time back, and still hasn’t recovered it yet. He was wondering - perhaps tongue-in-cheek - about installing tracking devices in instruments against such an eventuality. But it got me to thinking. Hmm, how James Bondesque, thought I. Why not? Could it be done?
I can’t wait till they’re small enough for cats. In the meantime, I will find out where my cat has been after he gets home, with this: http://www.mr-lee-catcam.de/ct_how_en.htm
Still too big. Something about the size of a pinkie’s fingernail, and just as thin, if possible. Or at least just thin. IOW, something you could attach to the instrument in a hidden-away spot that wouldn’t compromise sound quality; something for the case would be too dicey, as you could always ditch that. Flute, though…you’d want something small enough that you could hide inside the cap end; maybe ferrules that only look like just ferrules.
Just tie one end to the head joint, and the other end to your cat. Then listen for the sound of your carpet being clawed off the floor as kitty is dragged backwards out the door.
Emm, this might work for your loved ones, too. Again, just tie one end to their head joints.
Sigh. You guys sure have a roundabout way of telling me, “Just Google it.”
Found this site about mini tracking devices. At first glance I think that sort of thing, especially the one at the top, could fit with little detriment if any into the innards of guitar-like things and accordions (but lore suggests the latter are probably safe, anyway).
