That's the part I'm talking about, Butcher.


That aside, the cap alone definitely won't work: it's just going to suck up more power to get charged, because it'll be discharged at startup. The coil is what would make it happen, but it'd have to be hefty (as iroc pointed out), and that's going to have to involve a diode (as pointed out by Groth).

Maybe a PWM circuit would do the job here. Ideally, it'd have a low voltage startup sequence, or something... (but that's AWM).
