LED Emergency Light We have developed three circuits under Automatic LED Emergency Light. Two of them are designed by Mr. Seetharaman, a very valuable and important contributor of this website. We have listed the circuits here for your ease of  reading. If you have any doubts; please comment with circuit name or circuit number. 1. Simple Emergency Light using LED 2. Automatic Emergency Light using LM317 IC 3. Modified Version of Automatic LED Emergency Lamp using LM 317   1. Simple Emergency Light Circuit This is one of the most cost effective (cheap) and simple emergency light circuit developed for…

Touch Control Lamp Dimmer Description This is a simple touch dimmer circuit made of IC TT6061 . TT 6061 is specifically designed for this purpose.By touching this touch dimmer you can increase the light intensity of incandescent lamps in three steps At first, when mains  is ‘on,’ the lamp is ‘off’. When you touch the  plate, the lamp glows dimly. At second touch, the bulb gives medium light. On the third touch, the bulb is driven fully.Next touch puts off the light off. Line frequency is taken through R4 to pin 2 of IC.At zero crossing the IC fires a…
