Eliminating Next Mode Memory in flashlights.

  • gasbag11 Top 10 Forum Poster Sunday, June 1, 2014 10:52 PM Reply
    If you don't know what "next mode memory" (in flashlights) is, it's the extremely annoying mode system that causes a light to go to the next mode every time you turn it on. I.E.; Turn it off in high mode, it will be in mid or low mode when you turn it back on. Unless you have a good memory, it's a surprise which mode it will be in when you turn it on. Or you have to remember to set it to the mode previous to the one you want the light to start in.

    I got an amazing suggestion on another forum about eliminating "next mode memory", so I thought I'd share it with anyone who hates that mode system.

    This requires no special tools or soldering iron, unless the driver is soldered to the pill. (None of mine were) Just sharp needle-nosed pliers or pointy tweezers to get the driver out of the pill, just enough to to have access to the capacitor.

    NOTE: None of the drivers I did this on were soldered in. You may need to desolder yours if it's soldered in.

    If you can remove the driver board, than all you need for the mod is a sharp pencil. I tried it on 2 Ultrafire C8 lights, and was blown away when it worked. Simply draw a line across the top of the capacitor with a pencil, connecting one of the metal end plates to the other. There's a thread about it on budget light forum with some pics. http://budgetlightforum.com/node/14342 The first mention of it is on page 2 of that thread.

    I'm not an expert so I don't know if it will work on every flashlight, but it worked great on the 2 C8s (one of them was sku.184696) I tried it on. It was the first time I ever removed a driver board. (Yep I was a virgin till yesterday) lol

    Be advised that the capacitor (usually a brown rectangular component with a silver colored metal plate on each end) is TINY. You may need a magnifying glass if your eyesight isn't the best.

    I practically covered the whole top of the capacitor with the pencil and the memory only lasts about a half second now. It always starts on high, changes modes with a quick half press on the switch, and behaves just like a light with no memory. It's mentioned that if you're too heavy with the pencil, you won't be able to change modes and it will become a 1 mode (high only) light, but that didn't happen for me. Maybe I was just lucky. You can always start with a light line, then add more if the memory lasts too long.

    Anyway, I now have 2 nice lights that have been rescued from the "junk drawer". :D

    Update; Just tried it on another light. sku.121293
    The part about too heavy of a pencil line is true. It now has only 1 mode instead of 3. Still much better than "next mode memory" and it's easy to erase it if you want the other modes. So you may want to start with just one light line, and add more if necessary.

    I'd also suggest a really sharp pencil. The capacitor on this light was so small, I needed a magnifying glass to find it.

    Update 2. I ran an eraser across the capacitor (of the 3rd light I mentioned) and ran a single line across it with a VERY sharp pencil. It now works like any other 3 mode light without memory.

    Who'd have thought you could do a flashlight mod with a pencil? How cool is that!?

    I also did it on sku.102630 and it works great. All 4 lights start on high mode, will go to the next mode with a quick half press on the switch, and behave just like lights with no memory.

    edit - I posted this in another forum a few months ago. Don't know why I didn't think of posting it here until just now. Old age I guess. lol
    NO! I don't know why DX screwed up the site so badly.

    cyclist; I didn't know you already had a link there about next mode memory. lol I do think that my post today might be better because it doesn't go off topic like my threads usually do. Its up to you which you think is better. :)

    These newly acquired modding skills of yours will open up a whole new world to you GB… Imagine all those dozens of flashlights you’ve been avoiding just because they have next-mode-memory!... “Oh honey, where did you hide the credit card?”

    LOL Those newly acquired skills have already brought me a bitter disappointment.

    A light I had my eye on for quite a while, was listed as having 5 modes and next mode memory. Naturally, as soon as I knew the pencil mod worked, I ordered one. The light I got has only 1 mode. Its a nice light, but it only uses 1X16340, and since its very bright (maybe 350~400lm) it gets quite warm, and most of my protected cells cut off after a couple of minutes. If it had mid or low mode, at least it would be more useful. Once the pcb trips and shuts the cell down, the only way I know to turn it back on is to put it in the charger again. (not sure if all chargers do that, but the Nitecore does, in case you ever need that) As it is, its just a nice looking keyfob.

    edit - typo

    Does this work for ordinary memory modes? Will I be able to turn a torch on in the same mode every time?
