professional design timer circuit board recycling in nigeria

Environmental Issues in the Electronics Industry

It does not seem that anyone plans for recycling at the time of acquiring computer equipment. But, some early efforts are being made at the level of manufacturing. It is one thing to design a performing system and to make computers and personal electronics available to nearly all people. But, how does it affect electronics recycling?

THE FUTURE OF ELECTRONIC WASTE RECYCLING IN THE …

recycling rates, 332,000 to 649,000 short tons of e-waste were recycled in the U.S. in 2010. Currently, the main driver for the recycling of e-waste is the pressure of regulatory factors. Lack of national regulation has been shown to significantly hinder recycling rates in other nations (Solving the E-waste Problem (StEP), 2009).

Broken Wire Detector Circuit using IC CD4069

In this article we are going to make a Invisible Broken Wire Detector which is used to check broken or disconnected wires inside the walls. It detects the broken wire by detecting the presence of AC voltage in the wire. When there will be AC voltage present near it, then it will start beeping and LED will go high while when there will be no AC voltage or if there will be a broken wire, then ...
