modifying PIR to lower voltage

[Steven57]

Felix on your mod to get the PIR to operate down to 3.3v,,,,,,I could not tell by the picture if you were bridging all 4 pins of the regulator or just the right 2 to the top pin.
Clarify please?

Click on the photo, it gets blown up.

[Steven57]

blew picture up to 240% and still not sure if all pins are bridged or just the bottom right 2 and the top.
Clarify please?

I never thought that is not clear enough.
You're looking here right?

Do you see this picture (far right one)?


The far left of the regulator footpring pin is clearly not bridged to anything.
And let's think use some electrical reasoning and think about it.
If all the pins of a regulator would be bridged, nothing would work, why? Because one of those pins is GND (the one that is untouched) and VOUT would be shorted to GND, not a good thing.

Is this clear hopefully?
