Lexel can you provide a few more infos abou the driver?
1.Polarity Protection Yes or No
2. Overtemp protection and at what temp Or does it use stepdown (timecontrolled and when yes after how many seconds)
3. LVP at what voltage
4. Driver Name FET+5+1?
5. Bistro UI chart 100% usable for Bistro OTSM?
Makes Bistro sound plain and simple, when in fact it’s far from that…
OTSM as explained by Flintrock himself HERE
And TK’s Bistro Manual… the “plain” Bistro
The Bistro normal UI is copied from a listing made by CRX, thanks S. 
1. Its standard Bistro driver so yes
2. standard Bistro Temp setup
3. 2.7V Bistro standard
4. I count 6 AMCs total and see a FET
5. standard Bistro with triple v1.3 plus
Lexel,
I'm grateful for your support in this project and I think I can speak on behalf of the entire BLF/TLF that we all greatly appreciate your contribution. However, it would be much more helpful if you gave us some more detailed answers than the ones we see above. Please keep in mind that not only LuckySun's success is at stake but also every buyer's satisfaction with the BLF D80 V2. We need to get the manual finished by yesterday, so we are a bit in a hurry. Therefore, please have a look onto the following questions and reply as distinct as you can once again:
- Does this very driver has overheat protection?
- If so, at what temperature? (what is "standard bistro temp setup"?)
- Is this driver a FET+6 or a FET+5+1 driver? Do all AMCs run on only one channel?
- In terms of the UI and usability: Is there any difference between Bistro and Bistro OTSM and if so, is the UI chart (see some posts above) affected, so that we cannot use the Bistro chart for this flashlight?
- Will the temperature calibration (i.a.w. with the manual Dale kindly posted above) also work with Bistro OTSM?
Thank you very much!
1.+2.
- the driver has Bistro temp sensing, needs to be calibrated by user, there is a default of like 50°C but the MCUs spread up to +/-20°C
—> 5+1
Mode groups:
- TA made those as far as I know
If I say Bistro standard it means it’s all in the topics related to the firmware
The only difference to TA or OTSM is default Mode group is set to 4
Jacky has already printed the last draft version. So that's the version you will get along with your flashlight. I have supplemented the latest information Lexel provided yesterday and created a final version of the manual. This one will probably be shown on LS's website on AliExpress. You can also download it for more convenience from my Google Drive Sharepoint.
Hi Lux-Perpetua, appreciate your efforts in writing this Wildtrail D80v2 manual.
In the last part, is this a typo? “B duilding” or is that “B Building”?
I asked about the battery previously, but am not sure if there’s a possible answer — regarding the SST40 version, it says not to use >10A high-drain 18650s.
Does that mean, using a fully-charged high-drain battery (eg. 30Q or VTC6) will definitely burn out the LED when going to Turbo mode?
I’ve been running SST-40’s on FET lights since the 40 became available, using the hottest cells I can find. Have yet to blow an emitter but have seen them draw over 9A regularly. Doubt you’ll have to worry about which cell to use…
Like DB Custom said. Most SST-40 can even handle 9A. The led should survive even a high drain cell. They tested with a fully charged 30Q. We tried to limit the current arround 7A with the 30Q.
But its a commercial sold light and by recomending to not use a high drain battery gives them a bit more safety.
For the SST-40 version they are not using the spring bypass to keep the current down. And not using a high drain battery should keep the current also in a save reagion.
I must confess I do not have any idea if this strange look comes from a typo by Jacky or if it is really meant to be "B duilding". I took the address "as is" from Jacky's original first draft of the manual. As we had to get everything sorted so quickly, especially about the specs, there was no time to have it checked and possibly rectified. Sorry for that. :-(
The full diagram can be a little intimidating, since there’s a lot of stuff in it. I’ve been meaning to make a tutorial which starts with the basics and then expands to the other features gradually, to help people understand that the core usage is very simple. The text of the tutorial is already half-written, but it’ll take a while to make all the images needed.
Yeah, it needs some changes to make it more intuitive. And even then, I find it’s still awkward. Ramping just doesn’t work very well with a power-disconnecting tail clicky. So on most of my tail-clicky lights, I still use some of my oldest firmwares… S7 and Cypreus. I like them more than my newer and more general-purpose interfaces.
There is no firmware called Bistro OTSM. It appears to be a customized version of Flintrock’s Bistro HD.
As for differences, the names make it seem like the two are very similar, since it’s just “Bistro” and “Bistro HD”. But they only actually share a few lines of code. If I understand correctly, Flintrock tried to make the user interface very close to the original, but the underlying code differences are so large that it would be a good idea to test the firmware very thoroughly on a prototype of the light.
I haven’t really used Bistro HD much, since it never really worked correctly on any drivers I tried, but I can at least say I already see at least one UI difference between the diagram and what’s documented in Flintrock’s thread. Menu items 3 and 4 are swapped. It’s also likely that the number and details of the mode groups are different, and the manual really should have a list of what the mode groups are.
The difference is about 4000 to 7000 lines of code, depending on which parts are measured. For reference, the original Bistro is only about 1000 lines total. So it’s probably easier to list what they have in common, instead of what’s different: They share a similar user interface, and a few scattered stanzas of code.
As far as I’m aware, Bistro HD has only been used by a few people. This light will be the first time it has been used at a larger scale.
About OTC (original) vs OTSM (HD), the difference is:
- OTC (Off Time Capacitor) measures the voltage of a capacitor to determine how long the button was pressed. The driver fully shuts off at each button press, and boots fresh each time the light turns on. The button timing may vary with temperature though, since this uses the analog decay rate of the hardware as a way to measure time. Requires a bleeder resistor when a lighted tailcap is attached.
- OTSM (Off Time Sleep Mode) keeps the driver running for a few seconds during each button press, using the control chip’s internal timer to measure time. When power is restored, it continues from where it left off, without rebooting. Timing is much more consistent, but the chance of bugs increases since the driver doesn’t reset its state as often.
Yes, this is required by the license. The exact code shipped on the light needs to be provided.
“Mostly untouched” means it’s modified, and counts as a derivative version. GPLv3 sections 5 and 6 apply, “Conveying Modified Source Versions” and “Conveying Non-Source Forms”. Ideally, the license terms would be resolved in the manual, so the retailers would not have to care about the license. If the manual doesn’t include the right information though, retailers will have to carry the relevant information on their product pages.
But it’s not standard Bistro, not a standard Bistro driver, etc. It’s different hardware with different firmware.
The information may be in other threads somewhere, but it’s not here. The people running the project need exact, specific details… not a suggestion to look it up themselves and make guesses about which information is relevant.
TheOnlyDocc and Jacky were talking about the odd looking address but it's correct as it is shown in the manual. So, no corrections necessary.
Some more news I'm glad to tell you: I was also told that Jacky will print and supply the final version of the manual with the D80 V2.
Thanks Toykeeper for clearing some things up. I wanted Bistro in the first place because it is a proven version. Now i can only hope that everything goes well.
To everybody on the no ano list. Please check your mails. If you are on the list but have not get a message from me please contact me.
And for everybody else. Jacky told me that the sale will start this weekend. I have no exact date or time. But i was told Saturday or Sunday.
Yay, preparing my wallet!
Perhaps a stupid question so very late in the game, but do we have any known runtimes available for this light with either emitter? I’ve looked at the final manual and see nothing there…
Also, in general, should the XP-L HI run “cooler” than the SST 40 given the less amp draw?
Run time is of course a factor of the amp draw vs the capacity of the cell you put in. If the SST-40 is pulling 7A and you use a 3500mAh cell then you can expect, in theory, about 30 minutes. It will be different as the amp draw will drop as the cell dies so it will stretch out more than the theoretical allows for.
Cool running is again dependent on the emitter and amp draw, is the emitter at it’s maximum and how does it deal with that? The SST-40 does tend to produce some heat up at it’s max of 9A or a bit more, so keeping it down to 7A should help alleviate some of the heat issues. I’d expect the two emitters, in this case, to be fairly similar in heat production. We’ll see pretty soon hopefully.
Almost 20,000 Dale! Wow.
I can’t believe there aren’t more people celebrating this news! :partying_face: I’m looking forward to getting mine!
