Where can i find babyphone schematic ? anyone can show to me ? i want build some small simple microphone that transmitt via FM 88-108Mhz, when in other side use ordinary Radio FM Reciever. so i can always monitoring baby sound (or any wierd sound in baby room).
Look in Google for FM Transmitter Circuit. There are thousands of them and most are almost the same. The simple ones have the RF frequency changed by temperature changes, supply voltage variations and when something moves toward or away from the antenna.
