太阳能调频发射电路（英文）,Solar FM Transmitter

  This is a circuit of battery less fm transmitter, circuit is same as we discussed before in "BeST FM Transmitter Topic" but we changed the POWER source from 3 volt battery to solar cell. The circuit will work in direct sun light, use small solar cell of 3 volt to 5 volts 100mA and also experiment with different types of solar cell of 3 to 5 volts or above in direct and indirect sunlight. For more details about circuit please see the TOPic page "Best FM Transmitter".
