This is my circuit published in Electronics for You Magazine March 2010 issue.I have designed this circuit to reduce the inhalation of toxic chemicals from the liquid vaporizer. The timer action of the circuit switches On /Off the vaporizer at an interval of 15 minutes.This reduces the quantity of chemicals in the air and increases the usage time of the liquid.Full circuit is given as image .
