From the year 2000 I started to work with various electronics projects like radio transmitters, audio amplifiers, sound processing kits, digital logic circuits, microprocessor based device, etc. But that time I had very poor knowledge about it. After I increased my knowledge it became a serious hobby to me. I like songs very much and like to sing. When I entered to voice conference at any chat, I tried to use a voice effect with my microphone to surprise my friends. I simply use an ECHO and Delay attaching device. Recently I build a single chip circuit for Echo & Delay. At the same times I am working with High watt long range FM transmitters and trying to get permission from our ?Tele Regularity Commission?. If people here are interested about this hobby or any other electronics project, I will add my projects here.
