Timer timer, who's got the timer? (not the 328)
You didn't start counting Timers at '1'. did you?    S.

328P sleep current wildly different between two copies
A quick poke around shows a decent 100µF 6.3V electrolytic cap is expected to leak tens of microamps.  No, that won't take you to 150, but if you need 0.2?  Yeah. ...

Algorithm to determine if any number appears more than once in list
a) Randomize the list. b) Compare the first two items.  If equal, report duplicate. c) Repeat until you're sick of it.     S.

328P sleep current wildly different between two copies
Maybe a bit late, but I'll make one more stupid suggestion:  Smoke all the caps off your Arduino minis.  Start with the "big" electrolytic, if there is one.  Yeah,...

328P sleep current wildly different between two copies
Fair enough.  I had not read the spec sheet before commenting.  's worth noting that Brian Fairchild's meter says 0.4uA, not <0.2.  Perhaps the die temperature...

Medical Forum - trying to read O2 sensor
Points for trying to help, but I think at this time you're going to learn how little you actually know.   Many very smart guys have spent years building ventilators, and...

It's not entirely impossible that you did get two different chips - but instead of your thought that one was bad - perhaps it's that the other one was a wacky statistical outlier...

Measuring Inductance, best way?
Wrapping wire around nails is building a rail gun, not an inductor.  Hopefully few of those nails wound up halfway though the wall of the barn!  Your toroids were made...
