Radio Power

No, not a new Radio Station, I've been playing with an old mobile phone charger I was given to see if it would power my transistor radio.

Well, an LED and a resistor later, I can confirm it does work. By adding the LED I can drop the voltage of the unit to the 3 volts the radio needs. Excellent and free!

It means I don't have to keep buying AA batteries all the time, I can run the radio off the boat battery.
