Microphone/Mic FM Wireless is basically an FM transmitter to low power. FM Wireless Mic circuit you can use it to replace the wireless mic is usually quite expensive price.
If you are a fan of electronics, then the series is worth your trying, but its component prices cheaper tool is also very useful. Here is a picture of his series:
List Component of Microphone/Mic Wireless :
- 1 = 10K (brown-black-orange)
- R2,R3 = 100K (brown-black-yellow)
- R4 = 470 ohm (yellow-violet-brown)
- C1,C3 = 4.7pF (4p7), ceramic
- C2,C4 = 4.7uF-16V, electrolytic
- C5 = 0.001uF (1nF), ceramic
- C6 = 470pF, ceramic
- Q1,Q2 = 2N2222, NPN transistor
- L1 = 1uH, variable inductor
- Mic = Electret mike, 2 wires
Q1 amplifies the input signal via C4 from the electret microphone. Q2 acts as an oscillator and the signal coming off C2 is fed onto the base of Q2.
L1/C1 is a so called ‘tank’ circuit and operates in the 88-105MHz band on your regular AM/FM radio dial.L1 is a 1uH variable inductor coil to be able to tune it a little bit, and the range of 1uH is approximate. The antenna can be as simple as a 8″ (21cm) piece of wire of any kind.
