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

Thanks, this keeps coming up and I think one thing in particular is worth repeating again for readers who might be confused:

I didn’t create the Emisar D4 firmware. Tom did. Some of it was based on code from the firmware repository, but most of it was Tom’s original work.

How did I get involved? Around launch time, Emisar wanted some things changed and Tom was busy, so Emisar asked me to help instead. I changed several relatively small things:

  • added full thermal regulation with user-calibrated ceiling
  • added mode memory on click-from-off (default 100% 7135)
  • made beacon use current ramp level
  • made double-click toggle turbo (not just one-way any more)
  • made LVP drop down in smaller steps
  • calibrated moon to ~0.3 lm on Emisar D4-219c hardware
  • blink when passing the 100% 7135 level, for reference
  • fixed display of “zero” digits
  • fixed potential eeprom corruption
  • some code refactoring, cleaned whitespace, pruned dead code

Some of those changes were requested by Emisar, some were requested by people on BLF, and some were things I just wanted to change.

As for the FW3A… don’t worry. It’ll be even better. :slight_smile:

At your suggestion, I took a day off. :smiley:

There are certainly options, but it sounds like there is plenty of time before the FW3A will start production. The most straightforward option is to splice thermal regulation into NarsilM. The thermal code from the D4 would probably work with only minimal changes.

I’m probably going to try improving the thermal regulation algorithms soon though, because I had some new ideas.

And although it was “just some thoughts” a few days ago, now I’ve got a completely new from-scratch firmware almost done. So that might be an option. Or I’ve been wanting to try the FW3A driver’s light-sensing capabilities, which could lead to something interesting.

Things can get bad with too many cooks in the kitchen though, so I’m looking for guidance from Tom and the other FW3A chefs before I try to put anything in the oven.

I just realized the joke/reference on ToyKeeper’s avatar.

Palutena is the goddess of light.

That took me a while…

By the way, I myself modified (modified is a bit of a strong word. I changed 2 values) the emisar D4 firmware a week or two ago, so that it always goes to 100% 7135 on a single click, since people are talking about similar features. Personally, it makes for a much more useful feature than mode memory, because:

1: I can never remember the last mode I was in.

2: It has shortcuts to turbo and moonlight, but it was always keeping those in memory, which made the memory fairly useless, even if I remembered which mode I had used last. If it was moonlight, or turbo, I already have a shortcut for those. So I almost never had a shortcut for a reasonable level available.

3: It’s the highest mode on the d4 that still has something resembling efficiency. After that, we get into FET territory, which is far less efficient.

4: It gives a shortcut to the middle of the ramp. So if I press once, then press and hold, I can start going up the ramp from 100% 7135, which allows me to skip the lower half of the ramp. Want something in the 7135 range? Press and hold. Want something in the fet range? Press, then press and hold.

Anyway, UI is the kind of thing where everyone has their own idea of what is best. Nothing wrong with the D4 stock UI, just not my cup of tea.

I would also like to thank whoever did the comments on the D4 firmware. I don’t even know how to make a hello world on any language, and I managed to understand the D4 code.

That sounds good kaybl!

ToyKeeper is a goddess!

(Just ask Charlie Sheen.)

In!

Evening all,

Could you put me down for two of these please?

Thanks,

TOB.

Yes will update list later
But first the Q8 list needs updating, easy
And the ton of GT work has to be done today, so probably Sunday the list here for it was updated rather recent.

In, for one.

Does it look like cool white will ever be an option?

Hmm for now it is just one LED type. But no glue so easy to swap to emitter of choice ( and with the popularity of NW I bet it will be very easy to trade the LEDs for the price of posting an envelope :wink: )

Yes will update list later.

I suppose put me on the list as well. Full Narsil in a unique little light like this is pretty cool.

I recently bought a hot air rework station so maybe that will allow me to change the emitters.

interested in one

Please add me for 1.

Yes will update the list later :slight_smile:

Please put me in for 1

I sign up for 2

Of course Neal is swamped by all the GT stuff now
When it gets passed this busy stuff I am sure we can proceed with moving along and get the FW3A into the real world out of the computer :wink:

Will update list later

Please add me to the list for 1 of these beauties. And thanks!

Yes will do!
