Mod: Small Sun ZY-T11 and ZY-T29 + overview and comparison

Have you considered the following too?

-Low voltage cut-off. Say at 2,6V, its not like its much juice or light left in batteries then. I think its nice to have the protection. A true flashoholic always carries a spare keychain light anyway. Most have a cell phone too that can be used for emergency lighting.

Well, I did have that idea, but the number of features I can press into that small memory is limited, and I found other features more interesting.

-Low is nice and low, but is it possible to get it even lower?? :) (talking about the absolute lowest on ramping, not the default 1mode)

Well, yes, maybe, depends... The lowest mode is at the edge of PWM resolution and on the edge of AMC7135 activation time. The MCU provides power to them, they take a while (~2µs) to actually awake, and at that time the MCU drops power again already.

The problems with QLITE arise from that (flickering in the lowest mode, or lowest mode not even lights up the LED).

That's why I use a slightly higher, but safer minimum value.

Yes, can go to ~35 kHz, and even higher at the expense of PWM resolution - but why?

It also increases problems with the lower levels.
