I saw the mosquito device that will annoy younger people, but not older people: http://www.compoundsecurity.co.uk/teenage_control_products.html 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?)
It would likely be easiest to just make an electronic device like the one in the article... Use a 555 timer (or other simple oscillator) hooked up to a small audio amp, then to a tweeter. I know, I know, not a Linux solution... ;-) -TimH
