Fireflies ROT66 Flashlight

Why are you still messing with cr@ppy 8 pin MCUS ?

The days of DIY, or shabby “commercial” manufacturing, maybe with a hotplate or toaster oven, are surely over.

Sorry but this is reality.

Prove me wrong., please.

Re-calibrated the temperature sensor to be more accurate once the light was cold. The factory setting was still a good 7-8c off though.

The proof that you are wrong is right in front of you, if you could only be bothered to open your eyes and look.

I can’t say why these specifically, but we’re using such basic MCU’s probably because until recently, we weren’t using much of their capabilities. I mean, at one point, as far as I know the norm seemed to be essentially a convoy style Nx7135 single channel 3 or 5 mode light… doesn’t really need much of a chip to control that. Anyway, apart from the limitations we’re starting to have (and, after all - it’s not as if an atmega is gonna fit in a d4) they’re not that bad. Easy to program, for one thing.

My ability to resist finally broke down last night. My wife is probably not going to let me live down buying another light, but oh well. I went with black on the hope she’s less likely to notice it.

I’m really looking forward to my first experiences with Anduril and SW45K ranked emitters. The only other 219B light I have is just R9050 binned, I think.

It will be hard for her not to notice with the lit up auxiliary board! My wife was drawn to it right away like a magnet.

So true…. LOL! :smiley:

I'm still working on my cover story. Maybe if I mod my Convoys with illuminated tailswitches I can confuse her.

My fall back would be to distract with a gift, but she's not a jewelry person, so I've got to figure out something else.

I keep hoping that if she sees the right copper, brass, anodized titanium, or otherwise fancier lights, she'll catch the bug. So far, it hasn't worked.

I got is as a constant reminder of how it looks when I gaze deeply into your beautiful eyes honey.

The ROT66 is nice, but it’s not worth giving yourself marital problems. Don’t be deceptive about your purchases… Communication is important.

Fear not. I’m joking about the distress over how to explain it to or hide it from my wife.

I do expect to have to endure a 3rd degree eye roll and occasional teasing about an excessive number of flashlights, but both of us make discretionary purchases for ourselves rarely enough that items in this price range are a, “do we have a place to store it?” discussion, rather than a, “can we afford it?” topic. It’s definitely not a matter where reciprocation is demanded, although I would like to think of a comparable gift.

Or you cold always use Nev’s approach , although I definitely would not recommend it if you want your state of ‘maritial bliss’ to continue very long. :wink:

Says Nev whilst panically looking over his shoulder to make sure his wife didn't read that

Most likely…… :smiley: … :+1:

Well the last time when i bought a super big flashlight as a toy for myself (a 12” diameter HID, some 100W ballasts etc), my wife actually did jokingly “demand” that I get her a Chanel bag for her birthday! :person_facepalming: :money_mouth_face:

As for the other flashlights, luckily she thinks that i am paying like 1/3rd-1/5th the price that we are paying, coz as you’d all know we get it online, and online is always way cheaper than retail. :slight_smile:

The old "I got it for a steal at 60% off trick"...works every time lol

Has anyone had any drain related issues?

So far I’ve heard of 2 different lights that seem to drain the batteries to below 2.5V within several days to a week.

To drain three 3000mAh cells in a week, it would have to be running at about 53 mA. This shouldn’t be possible when the main LEDs are off though, because the MCU can only use about 6 mA by itself, and the aux LEDs can’t use even 1 mA… so the upper bound for those together is about 6 or 7 mA, even if something isn’t working right.

So I’m thinking it’s probably something else, like a metal shaving causing a small short… or something along those lines. But I don’t really know.

Regardless, the first step is to measure. Could you measure the standby power usage with a DMM? I would like to find out how much power it uses, and how that value changes over the first ~30 seconds of standby time. Also would be helpful to see if the value changes at all depending on how the button is pressed.

Also, which firmware is on those lights?

Shouldn't LVP kick in before 2.5V?
