Review: Fancy Flashlights Hi Current 17mm 1xAA Two Group Torch Circuit Driver

If these don’t have mode memory I give up.

I knew they were single mode and said it tongue in cheek. I seriously am in the poo if the memory on them doesn’t work. Cheers.

Light humor! Jeeze, I can be just a tad slow on the uptake :party:

Yes, but it has Mode Memory! It remembers to stay ON…

(In a far-distant thread

@garrybunk

“Next Mode Memory” is really just a “no memory” driver which is not reset to the first mode quick enough (i.e. it stores the last mode used for too long). These are usually corrected with a resistor mod to shorten that reset time. It’s not intentional programming.

(Feel free to correct me if I’m wrong.)

I moved this here to ask a question on this topic.

Has anyone managed to Reverse-Engineer one of these to discover which is ‘that’ Resistor? Wouldn’t it be salvageable if the reset were eliminated?

Or has the IC been identified (I am looking!!)? It seems the datasheets provide the schematics for a lot of these “proprietary” circuits… Except for the IC programming (e.g. hiding blinky modes)… I have that skill, so I’d LOVE to have a go at this one.
