Is there a summary somewhere in the differences between the first batch of 500 and the next revision, other than the manual… assuming there are any? If it’s all firmware tweaks, has it been published anywhere how we connect this thing up to a computer so we can flash the firmware if we want? I started perusing the thread elsewhere in the forums (which I really need to bookmark…) and grabbed ToyKeeper’s bzr tree. I’m very comfortable using version control and compiling software on a Linux and I know my way around the command line, but my experience flashing embedded devices is a bit more limited (mostly flashing routers and cell phones). I’m not sure if this will work with the existing clips out there or if I’d need to solder something up for use with the LT1. I don’t rightly care which rev I get, since I think it all should meet my needs and then some, but having the ability to hack the firmware and update it would be awesome.

TK posted a mice summary of the tweaks HERE.
As for reprogramming, I believe there are a set of spring-side programming contacts on the driver. I’m sure there’s a pic of it floating around, but I can’t locate it right now.

Edit – I think this is reasonably current. (click to open full) “under” the LT1 logo, you can see programming pads.

As for the technicals of How, the standard USBASP & related tools used to flash an FW3a or D4 will get you 90% of the way there.

The printed FW3A’s manual is perfectly readable and the Astrolux MF01s manual is quite readable too. Wink

Sorry, dumb question:

Should we be waiting for a message, or are we just using the “Joe sent me, my username is gottawearshades” method?

I thought I would have gotten a PM by now if I was going to get one.

If correct that would be another strike against the way this has rolled out. The LT1 is not a light that’s only going to end up in the hands of flashlight savvy BLF members. It needs an understandable & readable manual in the package not a micro-printed illegible set of instructions.

You’re not in the first 500 on the list, so I don’t think you’ll get a PM for the first batch. However, it seems you can still buy one via eBay (based on reports from others). Just make an offer of $49.99 and include your BLF ID.

My first unit is something like 178, haven’t received a code yet, I assume this is still in progress or should I take that to mean the first 500 units have been purchased?

I gave my BLF ID user ID. He just keeps giving me a link to the product at full price.

Now I need to think about whether I want to pay full price I guess.

Instead of participating in the mad frenzy for getting a lantern ordered as soon as possible (I could get trampled), I intend to let Sofirn fill my order when they get to it. It only makes sense since the folks here have gone to all the effort to coordinate the GB for us and I don’t need to try to “cut in line”. Frankly, I don’t undertsand the frenzy at all. It’s been almost 4 years and I’ve gotten along without one in hand for this long, does another month or 2 really mean that much? No, or at least not to me.

Maybe if they are gifts and I need to have them for Christmas, that might make the difference for a shorter delivery time.

Thanks to all involved for doing what you do and also for tolerating the “madhouse” that the GB has become. It’s amazing what volunteers can accomplish and I must admit I couldn’t do what you folks do for us, or I couldn’t do it for any length of time without losing it. I’m trying to say “Thank You!”. (I’m just reading and I’m beginning to lose it, hence this post.)

Calm down folks! After you all trample each other, I’ll step over and around the trampled and bloody bodies and calmly take possession of my lanterns requested in the GB and without the frenzy. You can do the same. Life is so much simpler and longer without the rise in blood pressure and possible adrenalin dump. It’s not life and death, just a light, albeit a very nice light.

Ditto. I’m just a lurker, so I don’t figure my opinion counts for much, but I’m happy to wait my turn. I’ll have years and years to enjoy this light once I have it, so what’s another month or two?

Is there any way to reset the color in the center or an indicator blink in the center like at each end

The easiest methods are:

  • Factory reset (default tint is 50% or ~4000K).
  • Or turn the light down to moon level before changing the tint. The tint resolution is very low at that level, so it’s easy to see when it crosses a boundary like 50%.

Thanks for the additional clarifications. To be sure:

  • Right now in the manual we have a “TURBO” referenced. Is it normal? And should we get rid of that and maybe just call it “MAX” then?
  • The default FLOOR for SMOOTH is currently described as level 1, is it right?

No need to remove it. If the user configures a lower ceiling, the true maximum will still be available as a “turbo” mode. By default though, the ceiling is set to maximum so it doesn’t have an additional turbo above that.

The default floor for smooth ramp is level 1 of the 150 total steps.

If I understand correctly, there were too many cooks in the kitchen, or coordination was difficult due to time zones, or something like that… so they decided to do it on their own instead. We probably just had too many people in the private thread where the process was being worked out.

Some parts will be messy. And that’s okay. So far it looks like things are turning out pretty well, with only minor details not completely sorted out before the first batch.

It’s pretty common for generic manuals to be written for an entire product line, without going into detail about what is different about each one. That’s basically where things started… just a normal average manual. But people wanted to make it better, and they did. You were a part of that, and it’s very much appreciated. You helped improve it from average to uncommonly good. Thanks! Smile

Translations are almost always difficult and incomplete or inaccurate, even with extensive tools to help, like an i18n library and a string translation database. This project didn’t have those tools, but has done pretty well regardless.

I also don’t understand why the firmware is still changing.

It’s a moving target, a rolling stone. The firmware runs on dozens of different lights and changes over time as development continues. However, the lantern has been classified as a “stable” build target for months, so it was ready a long time ago. Everything since than has simply been upgrades.

For example, people wanted some light painting features on the FW3A, so I added it. And now, woot, the lantern has light-painting functions. It’s kind of silly, but it’s there. A couple lights were having physical difficulties with stuck buttons, and I added some extra safety features related to that. So now the lantern has stuck-button protection. Etcetera. It’ll keep getting updates over time, because that is the nature of software.

It works with the HQ Universal ProgKey pogo pin adapter, and it might also work with a standard SOIC8 clip. The clip method remains to be seen though, since the wiring inside changed since the last prototype I saw, and I’m not sure if the wires are still long enough to pop the driver out that far.

The Q8’s driver was easy to reflash with a SOIC8 clip and a small screwdriver… no soldering required. And the lantern is based on the Q8. But we probably won’t know until production units arrive if the wires are long enough for that. Regardless, the HQ ProgKey is far more convenient aside from having to build the key first.

Yeah….probably should have coordinated differently. It’s also difficult to do things via a chat. If it had been a face-to-face meeting everything could have been resolved in 30 minutes. The problem now is how are they going to keep track of the additions? It would have been no problem for me since everything is in a database and I flagged the exported rows when assigning them a code. Since they are doing everything manually it has to be…………hard.

I had the scripts all written and tested and was ready to fire off the PM’s when Sofirn said they would manually send then out. As TK said……OUCH!

That all sounds like a reasonable explanation to me. To be clear, I wasn’t suggesting that they didn’t trust you or anyone in particular, just the process of sending out codes in an automated way. I wish it had gone differently for the reasons you’ve mentioned, and I appreciate all the work you (and of the whole LT1 team) have continually done on this project. I think I would have gone crazy with all the “with batteries!” and “why am I not on the list?!?” posts.

Sofirn is doing it the hard way and I feel for whoever is responsible to send these out and track them. I think it’ll all work out in the end, but it feels like I’ve got a bit of a wait until they get to me. I’ll just have to keep practicing my patience until I get good at it.

Not sure how that will be published. I was going to put a column into the files I periodically push to the cloud with who had been sent a code but then again I had everything stored in a database.

Thumbs Up Well said TK. There will be always those few who will never understand that these projects are done entirely free, & on a volunteer basis by a group of people who share common interests in the hobby and topic, and the work is done across only the internet form around the world, through here on BudgetLightForums, with time barriers, language barriers, communication barriers, and more. For anyone to expect things to be perfect is crazy, but i feel we all did a great job of getting it rolling regardless of the hiccups, glitches, and delays, at least its finally rolling into production for everyone, even after 3+ years from the start, which makes me happy no matter what.

I tried the eBay route and the bid was not accepted. Showed in stock, offered $49.99 and gave my name and number. Oh well I’m no hurry anyway.

Well spoken DBSAR! Thumbs Up 

I have joined the team very late in the process when Sofirn asked me to do something about the LT1 manual, mainly its translation into German. I must admit that when I asked for help on the content-wise parts I did not expect so many helpful people here who immediately jumped in and spent most of their spare time to get everything right and even to tie up the last loose ends that were still found once we thought we were finished, e.g. discovering that STEPPED RAMP is the default mode. We wouldn't be where we are now without this great help, so stereodude, also to you many thanks for your help once again.

I have kindly asked Sofirn to put some more attention to the whole process of making the manual, especially with regard to the schedule of launching new lights on the market. I volunteered to also help them with future manuals and I would be happy to be on board again with the next BLF collaboration.

Happy weekend to everyone! Smile

Cheers, Thomas

I’m kind of confused. Should I be making an offer on ebay, buying on GB, aliexpress, or waiting for a PM with a unique code? I’m number 1965 if that matters…?
