this is a device that has a sensor to detect the components present in an air sample, paired with a small computer that then reproduces the odor in a greater quantity thus amplifying the odor and releasing it. The device will need to draw from a set of liquid base raw materials that it could mix together to produce the required odor at the correct magnitude.-- vfrackis, Jun 15 2009 Old school manufacturer of this http://geekwhisperi...04/marshall-amp.jpg [normzone, Jun 15 2009] random, halfbakery
