Tools: soldering, electric iron, rubber gun, radio. Circuit diagram: Inductance is made from 1 mm enamel wire on the pencil around the 5 circle. In fact, I made it a wireless microphone that can be connected to the audio, only one 10uf capacitor is even connected to one end of the elective microphone above, that is, one end of the audio is connected to the 10UF capacitor. The other end of the microphone. This is my circuit: the power is 3-5V. Look at my housing. . Demolition of the universal charge. . . correct! The antenna is in the case of 30cm left and right, I didn't get it. I didn't get it: I received a radio should be around 100MHz to talk again.
