Q's...

Would future firmware updates be a possibility? Not on the production light, of course, since I guess we are too far into the process to make such a huge change, but as a DIY updgrade?

  Yes - 2 screws to pop out the driver, need a download cable, 8 pin clip, and USBAVR adapter. Download the HEX file

What is an LDO?

  Low Dropout Regulator: we use it to drop incoming ~8V from two cells in series to under 5V to power the MCU. Could be used for 4S input as well (~16V).

3 channels already existed on the H17F driver, but I don't think DrJones released the code, did he?

  No - Dr Jones doesn't provide source code to his main line firmware versions he sells, but he was instrumental in providing one of the original sample source code drivers

The Round 3 Prototype arrived today, wiating for me at home. I believe these are true V6 3D's based on the beam tint and output.

 

Here’s some measurements:

   On SONY VTC6 soldered tops at 4.21V,  lumens: 6,375 @start, 5,850 @30 secs, throw: 59 kcd (486 meters)

   On Samsun 30Q soldered tops at 4.19V, lumens: 6,260 @start, 5,800 @30 secs, throw: 59 kcd (486 meters)

   On Samsung 30Q button tops @4.19V,   lumens: 6,090 @start, 5,620 @30 secs, throw: 58 kcd (482 meters)

 

The new designed plastic ring

LED's, not perfectly centered but not bad. Centering pieces fit tight:

Center screw removed, 18 AWG LED wires, 2 mm thick MCPCB (round #2 was ~1.2 mm thick):

Driver views:

 

Round #3 still has great square threads:

Engravings improved:

Round #3:

4X SRK clone (Securitylng) on left with XM-L2 U3 3D's, BLF Q8 on right. Beamshots appear more bluish than they really are

Thanks a lot for taking the time to answer.

I have some experience with the H17F, and I must say, it is the most configurable driver/firmware I have tried so far. Really impressive.

Is there a readme or guide for more current/advanced versions of narsil? I kinda want to see what features to expect on the GT, although the stage of development is a lot earlier in there, so I guess nothing is set on stone.

All of this talk proves to me that trying to get into programming a few years ago wasn’t for me. I haven’t got the attitude for it.

It also proves that all of you guys are damn great at programming. I read the documentation for a few of Toykeeper’s firmwares back when I was learning to configure biscotti and bistro, and it’s incredible the amount of features she can fit on the same hardware that is normally limited to “low, mid, high, strobe, sos, off-time memory”.

EDIT: Low dropout regulator. It lowers the voltage from the cells to the attiny, to increase efficiency. Is that right?

The driver should be easily reflashable if you have the tools to do so, and the tools cost perhaps half as much as the light. So, yes, you should be able to modify it.

As for drivers with 3 or more channels… Wight released a 4-channel one in mid-2014. As far as I’m aware, no one ever built one and there was never any firmware for it. His FET+1 layout was much more popular. I think Mike C then made one, but only for his personal use. Fast forward a while; DrJones and pilotdog68 both released one within a couple weeks of each other at the end of 2015. A version of blf-a6 could run on it, but the FET was turbo-only with no PWM for dimming. Then the Q8 started in 2016-04. In 2016-05 I got one of the 3-channel drivers and promptly made bistro-tripledown, which IIRC was the first open project with 3-channel PWM. I released it in a dev branch but didn’t merge it into stable until 2016-09. Mike C continued his designs well ahead of most of what BLF was doing, and even released some including code, but they haven’t been part of a big project so they’re not widely used. More recently, several 3-channel designs are available and multiple firmwares support it, and there’s even a new project which should make it possible to buy a light with one.

So… progress is happening, just slowly and it has been a little disorganized.

The LDO is just a way to power the attiny on higher-voltage lights without exceeding its voltage spec, like a zener but with lower parasitic drain.

Right at the beginning of post #2 is a link to the google drive share that has the manual in docx and PDF format - it's 4 pages.

Smooth ramping, quick access to lowest level ,highest level and last level used. 12 sets of modes are featured, plus has timed stepdown or temperature stepdown, all configurable. Lots of options can be configured.

The FW3A, right? Already on the list for that one too.

That 3rd round prototype looks nothing short of perfect. In fact, there are some improvements that I thought had been given up, like the 18 AWG wire, instead of 20 AWG.

Congratulations Tom, best to your Daughter and her family as they adjust to sleepless nights…

And Congratulations to the team with the arrival of the new Proto #3 and it’s apparent success.

Awaiting further instruction.

Just to clear up any confusion, does the Q8 actually have a larger hotspot than the Securitlng or is it set at a brighter level and the camera is blowing it up to look bigger?

No tri blade endcap? No biggie. This one looks fine. Thumbs Up

Wow to a lot here!

Thanks for the triple channel firmware info.
Yeah DrJones is highly respected but doesn’t do open source a key factor for the projects I do.
He did, with TK helped with the first parts list for the driver though, pretty awesome in my book when little me asked these two heavy hitters and they answered and gave input.

Tom wowsers, gonna edit topic title later
Looks good.
Gonna check with Barry where the samples for the team are, for it seems a good check by us all is all that it needed to give the go!
Thorfire did good, also our German friends will love the Chinese Export marking as I do Big Smile
I missed that hot logo before.
Dang it looks professional, sweet!

The labelling isn’t as clear on the new version, cheapens the look. Having said that, its not a deal breaker.

EDIT Shouldn’t have viewed on a 4 inch screen. On a 26” now and I agree version 3 is better.

What do you mean?

It’s clearly sharper and better looking.

Now, working on it, this post thus also doubles as MARK Wink
Done list should be up to date.

When will the lights go on sale? Thanks.

Well it seems all we need is the samples for the team if Tom does not discover things needed changing.
I hope/think they are already on their way!

The markings look great
Guess how I know…..
Oh yeah

I just found

A small parcel in the mailbox

The usual plastic baggie

Didn’t think much of it so tore it open

Some white sheet padding

A small pristine brown box

Opened it

A sheet of black padding

YAY

It
Is
Here

.
This is prototype 2 of 7
I so hope other team members will find something too!
First look (not even put cells in it) sweet
SO HOPE WE CAN LABEL THEM SAMPLES!!

Great news Miller! That answers your question if the other 6 prototypes were send out as well as Tom’s one.
(oh, no, I’m so busy ‘till sunday night that I will not even be able to even check the mail for middle-of-the-road plastic bags Facepalm )

regarding the BLF Firmwares running out of space and IOs, what bigger MCU could be the next step? And can old code be used?
Lamps getting more and more nice / complex. I see multicoloured lights, some with displays, more or RGB status LEDs.

Can’t the AT84 and little more expensive and newer AT841 be seen ad future MCUs, more pins, more channels anx better power usage for the 841 if I understand Mike C correctly.

Looking forward to seeing what the team thinks of the Proto 3 lights. Thanks for the pics Tom! Those comparison beamshots are amazing as well. The “grouping” is obviously much tighter with the Q8 than the Securitying. Did they thicken the shelf or did the team decide it was ok with the shelf thickness from Proto 2?

Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone.

The shelf, we (well I) said it was OK for a thicker copper slab would add depth and it already worked great with a thinner smaller OD ledboard

Yes, I do believe the hot spot in the pics is bout accurate to what I'm seeing. It doesn't mean though the 4X SRK clone throws much better. Found in my notes back on July 5th when I did the full mod to that light I measured 52 kcd, but that was at 5,450 measured lumens @30 secs and ~16.0A tail (clamp meter). I never could get as much amps out of that light as I could with the Q8 prototypes.

This is good news you received your Q8, The Miller - bout time you get a look smile
