FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

Exactly .

Made a quad with my Blf X5 , quad xp-g3 s4 3a . Even with the small 14500 cell draws 11,5 amps and puts out at least 2.2k lumens , haven’t measured …

A suggestion for a German engraving:
TLF & BLF SONDEREDITION

Please add me to the list!

I will take one please.

Rob

Put me for one please

Gimme.

Yep will update list later
After reading of you “Awesome Archive of BLF specials” in the Q8 topic I did kind of expect your question TK :wink:

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.

I’m in for one.

right after clicking post here I copy paste it in the we (DEL, Tom Fritz Cawi and me) have about the driver :slight_smile:

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)

Huh, both FET and 8x7135, impressive fit for 17mm only driver.

the driver is bigger :wink:

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!

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.
