If this is to have a reflashable Narsil driver, and if there is no indicator LED, do you think there’s any chance of connecting a spare ADC-capable pin to LED- ? This would allow it to sense light levels through the LEDs when they’re off. Would be nice to have this for future expansion, like screen-based configuration.

Pin #7, where there used to be the voltage divider for the ADC, is free. There’ll be at least a solder-pad so something can be connected to this pin.

I was thinking more along the lines of having a trace built into the driver itself, and maybe some new firmware. I don’t know how long it’ll be before the project is ready to ship, but perhaps I could get this idea ready by then?

Basically, instead of a config mode, configure the light on a web page and apply the settings by pointing the light at the screen. Could also potentially be used for other things, but the main use is making configuration easier and more detailed.

Sounds awesome and if I am not mistaken Fritz is about to move the MCU on the driver design so hardware wise it should be feasible.
(But don’t forget what DEL, Tom and Fritz are talking about is like a strange language to me so I could be wrong Wink )

The FW3A will have a AT85 MCU that I know.
And it is supposed to have space for a clip Wink

(Let the nailbiting begin for what the big guns are to say about this)

This means giggle away on turbo whenever you want to smile or impress people yet use it as EDC on regulated modes to keep the heat in check and have long runtimes.

Huh, both FET and 8×7135, impressive fit for 17mm only driver.

This seems too nice to pass. I would like to buy one (1) of these when available.

Yes, DEL suggested a resistor between LED- and the pin in order to protect the MCU and also a pull-up resistor.

OMG onscreen programming, revolutionary but why not, screen-on /screen-off is binary afterall!

Seeking the light.

Not that most people will want to configure it, because Narsil is pretty awesome by default. But if the idea is of interest, I might be able to put something together in time. It might even use less ROM space, without the need for an extensive config mode. I’m thinking the visual-config protocol will just be an offset, a length, and a sequence of bytes to dump straight into eeprom. The fancy parts can go into the configurator web page, like allowing the user to choose absolutely any set of modes in any order, setting voltage and thermal calibration values, etc.

I’ve been meaning to do it anyway, once life settles down a bit. Would just be nice to have hardware which supports it without having to hack together something messy.

OK, I don’t need them, but since when has need ever dictated anything to me? I don’t have a BLF designed light that I don’t like a great deal.

Please sign me up for 2.

Well, I resisted for a few days — with such a nice light on offer, I don’t think anyone can realistically expect much more than that. Wink

Two, please.

Ok, first of all, yes indeed I wanted to run out to the shop and make my own, straight away! But the pain in my left arm and shoulder is just too intense to attempt it.

The squared shoulders give a nice grip to this small of a light, allowing a light (not heavy) grip without losing it. The bead blasted finish also helps the light feel easy to grip, instead of slick as it would be if it were straight off the lathe in a polished style. If the machining is run slightly faster the tiny microscopic grooves or lines from the cutting tool will also give grip, almost invisible but felt in the hand.

I would like to see it remain square shouldered, with the bead blasted and anodized clear.

If the logo or namesake could be cut clean through the inner tube before it is anodized that would be very neat, lessening the weight of the tube while giving a stylish report of where the light got it’s origins. I believe there is a new Manker light that has the name Manker cut clean through the pocket clip, it’s in this style that I’m referring.

And in this post, my 2 cents are cast.

So 20 or 22? It’s hard to guess by the sketch only.
It actually starts looking interesting as a compact host.

Can we make the clip ring flush with the tailcap instead of sticking up all around like that?

Talking about the clip, any chances of getting a deep carry clip?

A deeper clip would indeed be pretty nice. Olight does those well.

At least, I like it a lot better than the style I use on my Cypreus. It’s still good, but having a bunch of tail sticking out the top can be inconvenient:

Hmm FW3A engraved in/printed on the clip, Fritz how about that?
If it is made into a deep carry also a little more space for this becomes available
TLF BLF FW3A and a hole for lanyard
Wouldn’t that be nice?

Would love to see this flashlight in bronze, brass, or copper… no coating or anything. Just let it age naturally.
