Whaaat? Who has removed the picture link in my above post? There Gimli was, asking an important question concerning the above referenced cheap knives who wouldn't have lasted even 5 minutes in Knife or Death. :-D

If you wanna check it out, click/tap (not safe for work ;-) warning).

P.S.: E for excursionist. ;-)

Ok what the absolute madman is this pic…

You shouldn’t have said it’s NSFW. Now I can’t get that image out of my mind now.

Tales of Marvelous Emitters?
So E goes for Emitters.

I want 21mm, E-swich, efficient, stabilized, running Dark Horse (ZB replica) firmware on attiny85 driver, a replacement for H03 stock driver ;))

sound activated flashlight, so I can strobe four thousand lumens at a car that doesn’t give me right of way when I have it, just by shouting at them.

I mean it does exist, just not compact and out of the box:

The Manker Godmes was a Bluetooth controlled flashlight that responded to sound, or at least blinked to music. Ahead of its time. No longer in production, though. I just thought I’d mention a cool light most folks don’t know about.

One question. Do we have a driver available on BLF that would be able to drive 2x 3V or 6V leds (seperatly and/or together)?
Or 2x tripples with SST-20 leds (again seperate and/or together)?
Only gathering information at the moment.

The BLF lantern is two separate banks of 7135’s with a custom Anduril firmware that can do one channel or both channels combined to mix tint. I think Lexel even created a variation with a FET mode too but the current LT1 doesn’t have any FET.

So 2 channels but only with 7135 banks. The perfect driver for the thing i had i mind would have a 7135 chip for low on both leds and a fet for full power for both leds. So 4 channels in total. Would it be possible to do something like this with the attiny chips we usually use? Light would be a e-switch light (with lighted switch controlled by the mcu).
I am not sure if the attiny chips we usually use have enough output pinns for something like this

It’s technically possible with ATtiny85, but not very good. Since the ATtiny85 has only three hardware PWM outputs, the fourth output (or all of them) needs to be PWM’d by the firmware. Better chips are available, though. And some of the BLF members are working with some of those better chips. ToyKeeper has been working on a ATtiny1634. I can’t be sure, but it seems somebody said that the BLF LT1 uses that. It has more pins, more hardware PWM channels, and other features compared to ATtiny85.

And is cheaper and takes less board space.
Pure upgrade though Narsil doesn’t support it yet.

Thanks for the infos DavidEF. I hope this new driver project will work out. It would make some new things possible. Nice to know that they work on new hardware!
And infos how far they are? Or if it is looking good so far?
I really love toykeepers work (and i am thankfull she invested so much time in it) but with the new low vf leds and more new things comming, the driver hardware designs we have now are reaching its limits sometimes.
Some new Anduril compatible drivers would be really nice.

Well, loneoceans is planning to build a new buck/boost or switching driver and is asking for suggestions HERE. I have already suggested that he make it compatible with Anduril or Narsil, and I think he will. But I also asked if he would use a more modern MCU and port one of those firmware choices to it, and he said it is outside the scope of his project. Still, having a good buck/boost driver compatible with BLF firmware will help with those low Vf emitters.

Yeah…

@DavidEF
I checked the loneoceans project. It is really interesting. Narsil or Anduril would be a huge + . It is a pain to have to many lights with so different UIs.
To bad he will not go for a new mcu. Using a new mcu would open up way more option. But i take what i get :sunglasses:
But that is still not helping with the idea i have in mind. Will have to push it untill we have something new.

To change from the above discussion, I’ve been looking for a ramping, constant current driver with a maximum in the range of 700-1000mA for modding some small scale video lighting. This may exist somewhere but, if so, it’s proving difficult to find. There are ramping PWM drivers and there are constant current drivers with modes but they all seem to be for a 2+ amp minimum.

A 17mm buck for 1x18650 would be nice but mostly I’m just looking for something which makes it easy to step through outputs compared to soldering and desoldering 7135s. Something as simple as cycling through 100, 250, 400, 550, and 700mA modes would probably be plenty fine.

Anyone know of something like this or which could be reconfigured to do something close?
