Best FM Transmitter

A very good designed circuit of an fm transmitter to broadcast your music or voice around the house and yard. There are many circuits of fm transmitter on internet but some are very big circuits containing lots of coils and components, some drift their frequency, some eats battery very fast, some are small low power but not perform well and range is very short. This circuit is not only long range as compare to other 3 to 5 volt fm transmitters but also very stable and energy saver...

Solar FM Tranmitter

This is a circuit of battery less fm transmitter, the 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 also experiment with different types of solar cell of 3 to 5 volts or above in direct and indirect sunlight...
