  • Can somebody help me on the “Switch Backlight“ chapter. I’m confused of the behavior, and don’t want to translate something I’m not sure of getting.

  • Can somebody detail me this paragraph from the “Ramp Configuration“ section: Note the default (after a battery change or other power interruption) for LT1 setup the smooth ramp will turn on at level 65.  For the stepped ramp, the output level choices by default are 10 / 45 / 80 / 115 / 150. The LT1 will turn on at level 80 by default.  Once the floor and ceiling levels of the LT1 are changed as described below, the LT1 will remember these changes even after the power is interrupted.  After the stepped ramp is changed the lantern will come on at the programmed level closest to 65.

    1. Why does STEPPED and SMOOTH does not share the same default (65 vs. 80)?

    2. What are the various defaults for SMOOTH? Or on the opposite why are there multiple defaults for STEPPED?

    3. Why does the STEPPED RAMP would want to be as close as possible to level 65 on start after a programmation?




  • They are needed so I can fully finish the translation.


    I’ll try to help. Not sure what your question is on the switch backlight, I didn’t go back and read all the posts closely, please ask a detailed question.
    As far as your 3 questions on the ramped configuration section go,
    1. That’s the way ToyKeeper designed the firmware. default is level 80 for smooth. In stepped, the region between the bottom and top of the stepped range are user configurable, and the firmware divides the region up evenly depending on the user’s choice of steps. ToyKeeper chose the defaults listed. For stepped ramp, the default is the level closest to level 80, which is 65 for her design of the default. Hope that explains it.
    2. Hmm, not exactly sure what your asking. The defaults are listed on page 2 of the english version in the section called Ramp Configuration, 3rd paragraph. Is there more your looking for? All of this is user programmable, so once it is changed by the user the “defaults” change.
    3. The grammar in this question is hard for me to understand. I think the answer is that’s the way ToyKeeper programmed it. You can never change the level wanting to default to at (smooth ramp) or near as possible (stepped ramp). You can change the bottom and top of the ramps independently for each ramp type, and the number of steps for the stepped ramp, but not the default level at which the lantern will turn on with a single click after the battery is replaced. Once the user changes the factory defaults, they can be reset, but I don’t think that got put in the manual as to how, at least I didn’t find it at glance right now.

      3. Why does the STEPPED RAMP would want to be as close as possible to level 65 on start after a programmation?

    sbslider addressed question #2. Let me see what I can do about question #1.

    The LT1 has three LEDs behind the power button cover: a green one, a red one, and an amber one. The green and red LEDs are controlled by the USB charging circuit and their behavior cannot be changed. (Their behavior is described in the “Integrated Charger” section.) The behavior of the amber LED can be changed by specific combinations of button presses.

    When the lantern is on, the amber LED will also be on. This is not configurable. If the lantern is not very bright (output level 64 or lower), the amber LED will be on at its “low” setting. If the lantern is brighter (output level 65 or higher), the amber LED will be on at its “high” setting. This behavior is also not configurable.

    You can configure what the LED does when the lantern is off. There are two different configurations: what the LED does when the lantern is off but not locked out, and what the LED does when the lantern is off and locked out. (The English manual calls these “OFF”, and “LOCKOUT”, respectively.) For each of those states, you can set the amber LED to do one of four things:

    • Be off
    • Be on in “low” mode, which is less bright
    • Be on in “high” mode, which is more bright
    • Blink on and off; when on it’s, IIRC, at its “high” brightness

    By default (according to the public Anduril source code), the amber LED is on High when the lantern is off (and not locked out) and on Blink when the lantern is locked out. (ToyKeeper, please correct this if the behavior of shipped LT1s is different.)

    When the lantern is off (and not locked out), if you click the button seven times the amber LED behavior (for off mode only) will change from its current setting to the next setting (off -> low -> high -> blink -> off -> …). Similarly, when the lantern is locked out, if you click the button three times, the amber LED behavior (for lockout mode only) will change from its current setting to the next setting.

    I think that covers everything, but please ask if you have more questions.

    I just checked Amazon (US) and it listed as in stock for $69.99, not eligible for Prime, and delivered Oct 31 – Nov 22. No option for batteries included yet.
    We are still getting the logistics together to send out the buying instructions.

    Once everything is in place I will start sending them out.

    That’s the Thorfire button, I guess they reused an old 3D model button for that picture.

    Please confirm that these are a good choice for protected cells for LT1?

    https://liionwholesale.com/products/protected-lg-mj1-18650-battery-genui...

    Decided to go with protected cells as I have 3 young kids and while I’ll teach them not to play with it, it’ll give me peace of mind that if one of them (or their friend etc.) did open it & reverse the cells then there’s an extra layer of safety.

    Thanks!

    Many thanks guys, really. I now understand what was previously missing to me. I can finish to translate that and making sense. Great job!

    Small detail for STEPPED: so that does mean that, the user defined # of steps is persistent after power loss?

    Yes, that is correct, the if the user changes the number of steps from the default (5) to another number, that updated number is saved when the power is removed.

    FYI I will be posting status updates, etc in status update thread . You may find it easier to see what is happening there rather than here.

    That thread is only for status updates, issues, etc so hopefully we can keep things to that.
