Oscillator

Hello boys and girls

I need a 15hz oscillator that operates from 1.2 - 2.4 volt and gives intermittent pulses to a coil / speaker

it is supposed to operate in the same way a solar powered garden light but with a built in rat scare

So, we have a solar panel as input, battery output for charging / using , a led that is lit when solar panel is not

receiving light and a oscilator as per description below.

It should activate when the batteries or solar panel have power and emit a 15 second long 15hz signal, then wait for 5 seconds and repeat .. until the battery is dead ..

maximum power to the speaker / coil is 10 ma charging current is max 4v 80ma and the led is maybe 15 ma

We are talking small power here, the simplest circuit wins this !

I require a veroboard or similar test version, schematic and pcb layout.
