I saw the mosquito device that will annoy younger
people, but not older people:

Its pretty expensive. How would I begin to create that
from scratch? Can a sound-card generate those frequencies?
I imagine I would need a special speaker.
How about an amp?, does that also need to transmit the
higher freqs.? Is it like going from a bass amp to
a guitar amp? (and I need to keep going?)
Whats good software in linux to generate certain frequencies?
thanks for any ideas,
