Mini FM transmitters take place as one of the standard circuit types in an amateur electronics fan’s beginning steps. When done right, they provide very clear wireless sound transmission through an ordinary FM radio over a remarkable distance. I’ve seen lots of designs through the years, some of them were so simple, some of them were powerful, some of them were hard to build etc. Read the rest of this entry »

You can comment here if get something wrong with this electronic schematic design

Here is a small project about FM receiver that you can built with a little cost. The schematic below

This is a very simple kind of receiver. The dificult point is to get the inductor coil, i think there a no electronic store that sell this coil. so you must make it by yourself
