Dollar store sells cell phone chargers which reduce the 12v vehicle voltage by about a third with a fairly simple coiless circuit.
Could these be easily adapted to 8 - 8.5 volt chargers? Maybe put another resistor in parallel in an RC circuit? 75 ma - 200 ma is all that is needed.

Apparently there IS some kind of ~ 1.5 Hz voltage fluctuation somewhere in the circuit.
I wonder if this would be a useful oscillator frequency.
