comment Is my circuit hitting a limitation of the AND gate on IC 74HC08N?-- How does PWM frequency affect performance?
Where did you source the chip from? Also, what is generating the PWM?

comment lt1076 buck boost converter outputting voltage that is too low
Nothing jumps out as being wrong. Inductance sounds right, and it has plenty of current capacity.

comment lt1076 buck boost converter outputting voltage that is too low
Absolutely nothing. I'm being facetious. The inductor doesn't care.

comment lt1076 buck boost converter outputting voltage that is too low
Ah well, there's the problem. You're using a NatSemi inductor with a Linear chip :P

comment Transistor as a switch
They're both right. The yellow box is for saturation, the red box is for active mode.

comment Transistor as a switch
hfe is irrelevant when the transistor is saturated. It will help you get there, but once you're there it doesn't matter all that much.

comment How to get 3.3V from 2 AA batteries?
An inductive driver (by which I mean an inductor driven with PWM) could probably light them. Although to be fair, I haven't tried it myself yet.

comment How to get 3.3V from 2 AA batteries?
Why not switch to a device that works all the way down to 1.8V?

Don't crush them, and make sure the channels are lined up perfectly.

comment Low temperature solder
We cannot recommend low-temperature solder. Especially since they usually contain things that make lead look as harmless as a flower.

comment How can I easily convert an analog signal to a digital signal?
The TLV3011/12 is a low-voltage comparator with built-in 1.2V reference in a SOT-23-6 package.
