you said Joule Thief?  you said Joule Thief?  It’s a little wisp of a circuit that allows you to drive aPOWER  LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 – 3.5 V, like from a 3 V lithium coin cell. But the magic of JT is  a 1.5 V battery like a AA cell simply will work.  Easy make  Joule Thief,  works like a charm. Not only does it work with a brand new battery, but it works until the battery is nearly dead– down to 0.3 V.  That’s well below the point where your other toys will tell you the battery is dead, so it can steal every last joule of energy from the battery (hence the name). how about a cellphone charger , yes it is doable , we are here to give you  a usable tested diagram . get  the ring toroid from a OLD smps of pc ! 

An inverter is a daily used household device ..to create an un-interrupted on 220V AC or 110V AC (the AC voltage depends upon the line voltage of the specific nation) supply to the gadget associated as alternate power to main  socket.The inverter gives consistent AC voltage at its peak hours with auto turning on when the AC mains control supply isn't accessible. The modern inverters work very silently and there are very few indications .  The SUKAM , luminous ,Microtek etc companies have dominated this segment .  Every year crore profit is taken out from ASSAM just because we do not have engineers who will join hands to create a makeINaxom inverter prduct line . 

Cell phones are many the  screen is one constraint that has not been addressed . The flip phones has  dual screen but all hated the begels . The flex OLEDS ::  As the availability of consumer OLED-display products continues to expand, so have research efforts in future trends of the low-power, light-weight, and superior-viewing-enabled OLED technology. Bendable, rugged, and eventu-ally roll-out flexible OLED (FOLED) displays are actively being developed by numerous university and industry groups, taking advantage of the demonstrated flexibility of both small moleculel and polymer2 OLEDs. The key chal-lenges to be overcome for the realization of flexible active-matrix OLED (AMOLED) displays can be classified into three main categories: substrate/backplane development, OLED development, and OLED display lifetime. Substrate and backplane development are interrelated in that the backplane technology chosen will depend on the limitations (thermal, chemical, etc.) of the fl...

- In 1994  , two cell towers were  installed on a five story apartment building in London. Residents complained of many health problems in the following years. Un expectedly Seven of them were diagnosed with cancer.This is marked as " cellphone tower of doom "
