__Emergency LED Light
_ Here is a simple LED emergency light circuit that you can implement for home lighting during power failures. We know that LED bulbs consume very less power and hence they have a much longer life. This led lighting circuit design is intended to light automatically during main power failures.
So here we are going to help you with the building of cheap emergency lights. The main part of this led lighting circuit is a relay, which automatically connects DC voltage to the battery when main power is present and connect LEDs to the battery in the absence of main power supply.

Simple FM Transmitter
_ Many times we want to make fm transmitter which is
simple to build and has a good range. So here is a simple fm
transmitter circuit which contains only few components and also has long
range
Here, is a very interesting and simple project in the series of communication used to transmit noise free F.M. signal in the wide range up to 100 M using only one transistor. The transmitted message from F.M. transmitter circuit is received by the receiver having the facilities of F.M. channel or you can also try F.M. receiver circuit published in this website.
