I'm not sure since I didn't write the manual, but looking through it, I see at least three links to threads on BLF. The only required link is the one necessary to satisfy the license. Since it uses GPLv3 code, it needs to have a prominent notice somewhere that it uses free software distributed under the terms of the GPLv3 license, and the source code is available from [link to the code]. And that legal requirement is satisfied, so the rest of the links are more of an editorial choice. I haven't really been involved in that.

The charging circuit and driver circuit work totally independent of each other, with no awareness of what the other one is doing. The driver has no idea whether its power comes from batteries or USB.

Stepped.

The only way to exit momentary mode is by physically disconnecting power.

Blinkies : are there really two different way to access them from the same OFF state?
There are two different sets of blinky modes -- blinkies (3C) and strobes (3H). It might make more sense when looking at the UI diagram.

Hello Toykeeper!

1 - I'm totally ok with GPLv3. My point is really specific to the intro/title/first page. It's only I'm surprised there is no reference to this crowd-designed cradle of the LT1 right in the introduction. It's a pretty unique origin that, I think, deserves emphasis. There is a link to BLF and even a full sentence about the community, true, but at the very end.

2 - Ok

3 - Ok

4 - My "acceleration" question is refering to this part:

Momentary mode disable:

physically disconnect power (unscrew the base from the head to break the electrical connection for at least a few seconds, clicking the button will speed up the process).

  • I'm unsure if "clicking" here means one click, multiple frenetics laughing clicks or even click and hold?

5 - Now understood, thanks to you. I think my confusion is coming from the fact that at various places in the manual the "blinkies" word refers to both "strobes" and "litteral blinkies" altogether, whereas it also is used solely for "litteral blinkies" at other places.

Rise and Shine my precious...

I see two totally different screws there, an allen head and a cross head – anyone know which one is production?

Looks good!

Yes, this is a good point. It is nice to recognize the contributions of the community who made this light possible.

All I was saying is that the legal requirements have been met, so any additional information is somewhat optional. Adding text to recognize the community is good though. It will depend on whether you can coordinate changes with the authors and translators quickly enough to meet the printing deadline.

Ah, that makes sense.

To exit momentary mode, it is necessary to disconnect power and wait until the driver’s residual charge has drained. If the button LED is lit up, it will drain that power in a small fraction of a second. But if the button LED was not enabled, it could take a few seconds before power is drained completely. Pressing the button causes the charge to disappear immediately. It does not matter how many times it is pressed or how long it is held. It only takes a few milliseconds. Anything after that has no effect.

It is probably not necessary to press the button at all though. Power should drain fast enough either way.

First of all, I think we have achieved to make a very profound, comprehensive yet understandable manual. I did not do most of the contentwise work, so credits go mostly to sbslider and stereodude. However, I took the liberty trying to answer to your points. Thanks for your input.

fneuf wrote:

As Toykeeper mentioned already, there are references to BLF in the manual, especially on the very last column incl. credits to the BLF LT1 team.

 

fneuf wrote:

The order in the battery brands suggestions does not look like random. I'd suggest to use alphabetical order to avoid the creation of the feeling of subjective inclinations.

Noted, but not a real issue that would require to edit the manual once again. However, I will try to consider it with the next update.

 

fneuf wrote:

We write to use 5V USB sources in the safety precautions paragraphs, but later we say the user can go up to 15V sources. That feel inconsistent.

Not necessarily, as 5V is more or less THE standard USB charging voltage whereas higher voltages can still be used for special equipment (e.g. solar charging). Using 5V as a general recommendation for charging in the safety precautions will not be conflictive to a more detailed description in section "integrated charger".

 

fneuf wrote:

Should the diffuser be described more as "textured" rather than "opaque"?

I'm not a native English speaker but I guess "textured" would describe something else, like a certain pattern as in orange peel reflectors for instance. Opaque seems to be a quite common expression for a diffuse surface.

 

fneuf wrote:

I saw so far no words about protected or unprotected battery compatibility?

Not necessary, as the maximum length is stated with 70mm length. Both protected and unprotected batteries will do fine as the LT1 is not using an FET but constant current regulation with 5x 7135 AMCs.

 

fneuf wrote:

There are multiple references to the button-top batteries, do we really need to repeat it each time?

Yes as this is a crucial prerequisite to safely run the LT1. Using flat top batteries can cause voltage imbalances and subsequent damage to the LT1.

 

fneuf wrote:

To ease the natural ordering of the "Quick Start" part, I'd propose to numbered the main steps. Step 1, step 2, etc

Noted. I will try to consider it with the next update.

 

fneuf wrote:

For disambiguation, I'd suggest to use "battery charger" instead of just "charger" (that might be mixed with USB charger).

Noted, will be considered for future updates/manuals.

 

fneuf wrote:

"70% max on ext. source" part is confusing. How the user is supposed to control/even know this figure? Shouldn't the LT1 automatically lower/control its output regarding the energy source?

This topic has been discussed within the BLT LT1 team already and we decided to keep it this way. And yes, the LT1 will run at reduced output without batteries installed but with a USB-C energy source powered.

 

fneuf wrote:

Some instructions are repeated. Like maximal dimensions of batteries (first paragraph, and again in specifications). General rule : are repetitions voluntarily made or can be "smartly" controlled?

Noted, will be considered for future updates/manuals.

 

fneuf wrote:

Is the default mode stepped or smooth? Various paragraphs states one thind and the opposite, notably specifications and UI.

The default UI is STEPPED mode (like Toykeeper said already). This is a major difference to any other Andúril-driven light as these have SMOOTH RAMP by default. I agree with you that there is one spot I have overlooked - shame on me - in the specifications. Here it says SMOOTH RAMP by default. I will check with Sofirn if there's any chance to submit a correction.

 

fneuf wrote:

What does mean " double-click (green double lines)" ?

See UI diagram for reference.

 

fneuf wrote:

Some things looks not perfectly ordered. For instance, in UI texts we speak about levels (as in level 150) before introducing what levels are and what does they represent.

Noted, will be considered for future updates/manuals.

 

fneuf wrote:

Acceleration command to leave "MOMENTARY" mode is achieved while HOLDING or with multiple CLICS ?

See Toykeeper's reply.

 

fneuf wrote:

Why not "for simplifying the UI for users who want a simpler experience."=> for simplifying the UI for users who wants an easier experience." or something the like?

Noted, but not a real issue that would require to edit the manual once again. I will try to consider it with the next update.

 

fneuf wrote:

I'd propose that MUGGLE have an added explanation stating that it also intent to securise the usage of the LT1.

This is already addressed on page 4 ("usage of the LT1 lantern").

 

fneuf wrote:

Blinkies : are there really two different way to access them from the same OFF state? If yes, this might be confusing (  "do either a 3 clicks (3C)  from OFF or a 2 clicks and, hold” (3H) from OFF")

See Toykeeper's reply.

 

fneuf wrote:

"3.1 volts or lower" => why not directly state "lower than 3.2" ?

No offense, but this is nitpicking, isn't it? Wink To be more nitpicking, lower than 3.2V is not the same as 3.1V and lower. Silly

 

fneuf wrote:

Correction Click three times, but hold the third click until the strobe mode stars.=> Click three times, but hold the third click until the strobe mode starts.

Noted, thanks. Will be rectified with another update later on.

Can you put me down for one more? For a total of 2. I think my parents that live in Africa need an LT1 for the nights with no power. Also, thanks SigShooter for all the admin work with the GB list. It’s appreciated!

Longtime user of American English here and sometimes I even manage to get it right. Big Smile Hopefully this is one of those times.

Maybe better words to indicate the treatment could be “frosted” or “translucent”. That type of surface is one that allows light to pass yet doesn’t allow for clearly seeing through it and is done on a microscopic level. As Lux-P’ wrote, texture is how something feels, mostly on a larger scale rather than a micro scale. There might be other ways of using the word, but that’s the one I’m using here without using a dictionary..

“Frosted” and “translucent” both describe the characteristics better than “textured” or “opaque”. Opaque implies that it doesn’t pass light at all.

The LT1 in the sofirn shop is really expensive, 99 USD without and 125.99 USD with batteries.
I estimate them to be early-adopter prices.

Agreed! I will incorporate the latest (and hopefully very last) changes once again and submit Sofirn a revised version tomorrow.

All objections noted and replied above will also be adressed as far it is reasonable and possible. Thank you guys for your great help.

As a german, i’m surfing the web mostly in german.
As a result, Alibaba shows me a german article description translation, which isn’t bad.
Its abysmal.
Even Google Translate would be ashamed producing sth. this bad.
While i’m and most people are perfectly capable reading the english manual, i’ve got two other concerns:
- this throwing a shadow on the otherwise great LT1 for non-forum-consumers
- i’m not shure if the (somehow understandable) mentioning of the andruil firmware fits GPL v3 requirements. Proper german would be sth like:
Firmware: Die LT1 verwendet eine Open-Source-Firmware namens “Andúril”, verbreitet unter den Bedingungen der GPL v3. Der Quellecode ist verfügbar unter “http://tiny.cc/TKAnduril” .

Group buy price is in the OP, 49.99 for one LT1, 62.99 for one LT1 and 4 Sofirn 3000mAhr batteries with button tops. No codes as of yet. You can try to buy it for 99.99 in the Aliexpress Sofirn store, not sure if they will meet their suggested delivery times.

On the product page, it says delivery to the US by 10/24. If you put one in your cart, it says delivery by 10/29. Either way it continues to seem very close to release. Also, limited quantity. I’m pretty sure the group buy price/codes will be through Amazon, but subject to Sofirn’s final decision.
