This is another super cool project from Householdhacker.  He put together a gadget to listen in on cell phone, and I am assuming, wireless home phone calls around your neighborhood. Now I know that good ol GW has been doing this in DC these past years but I am not sure we are allowed to.  It may be a good idea if you are worried about who your teenager is calling or spending time with.  Looks really simple but I would be suspicious to see how well it works in real life.  Anyway, another cool trick for you to try at home.  Take care.
