He is trying to pick off 1.4v but I think he needs 2 more diodes in
that shunt around the bridge because .7 v will be lost in the bridge.
I doubt the door bell that exists will miss the 2.1v he is stealing
but it might not quite as loud.
I do think I would go another way tho.
How much current does the 1.4v load need?

Perhaps a circuit between the capacitor and the 'buzzer' with say a battery

The LM317 is s 3 terminal to220 device, an adjustable voltage regulator
so that could be used to lower the voltage and instead of the full wave
diodes use 1 for a half wave supply, with a decent cap that would be Ok
for your purpose.

I still don't know what your talking about. I'll just by a button together
with a remote chime, ok? And BTW, I don't have a purpose. I live in a pre
-manufactured house and can hear anyone knock on the door anywhere I am in

Yeah... they almost respond the same. Take you from point A to
One just wiggles in the water a bit differently than the other.
You could make a doorbell that has the sound of "Flipper" when the
button is pressed. You'd have to be old enough to remember what sound
I refer to though.
And you can then sell it in Japan for a huge profit. If you can
handle the fact that they want to eat it. :-)
