There is a commercial device with a similar purpose. It uses a small gas flame to produce a little carbon dioxide and warmth. The flame is inside a tortuous trap, with either a bug zapper or a sticky substance (can't rememmber) to kill the little buggers. Mosquitoes are attracted by carbon dioxide (from breath) and then zone in to a warm object (a body) to do their nefarious business. The devices are supposed to clear mosquitoes effectively from several acres. Commercial bug zappers are useless - they mostly kill moths and other non-target species. Mosquitoes only blunder into them by chance, they are not attracted by the lights. Why do so many hicks buy them? Seems like a much simpler method than triangulation and directing a laser. Don't try to sell one, it's patented. No PICs in it either. -- Lawrence Lile ----- Original Message ----- From: "Diego Sierra" To: Sent: Thursday, June 14, 2001 6:11 AM Subject: Re: [OT]: Detecting a flying mosquito > 14/06/01 11:38:17, Diego Sierra wrote: > > >Hi! > > > >Is there something that can be build to detect the direction where a flying mosquito is? > > I was thinking in something able to drive a laser beam to fry it ;-) > > Cheers, > Diego. > > -- > http://www.piclist.com#nomail Going offline?
