I remember seeing ads for video cassettes that did the
same sort of thing
... load it into your VCR when unattended, and it'd scream (seem to
remember pictures of big cats??) when moved.
I've never seen them for VCRs before, but it doesn't surprise me. I have
seen recently similar alarms that you can put on furniture or other items
you don't want a pet on, and when it is jiggled or otherwise detects the
pet (I think some are infrared detectors), the alarm goes off briefly.
I did like the one I saw that was an electric pad. When the pet climbs on
the pad, their weight activates it and they get a shock. I'm sure its
harmless, but I'm not sure I would want to go shocking my cat on a
regular basis (but I have thought about doing the same thing with the
screen top to my lizard tank that my cat keeps climbing on and then
falling thru).
This is of course when VCRs
cost ?400 (US$700) and not the ?29 (US$49) I've seen them recently...
I just paid US $14 for a DVD player for my father for Xmas. He's been
complaining he wants one, but I know it won't ever be turned on... so I
bought one that was on sale, had a $10 rebate, and I used "Best Buy
Bucks" from a McDonalds promotion that I had saved up. When I was done,
total cost was $14. (and they asked if I wanted the $30 extended warranty
on it!!!)
A bit of a price difference from my first DVD player that cost me $500.
Of course, I also suspect that my first player will be running happily
years from now, when the $14 model has long since died.
