*BLF LT1 Lantern Project) (updated Nov,17,2020)

The most fashionable night light in the street:

You can try to enable all the 7135’s and configure the ceiling with 130/150. With this you have a similar lumens in the top of ramp with 5x 7135’s and maximum power with double click, like others Anduril flashlights.

is there any chance for the 2nd batch......

Just so that there is no misunderstanding, yes, no, and maybe.


nice to see another with understanding

A chance to get on the GB list? or or of the batch codes being sent out? If you are already on the GB list, have patience,they are under production now, and they will build them before beginning to send out the codes, (so they can be shipped right away once they are ready.) Also see post #9127, page #305.

For anyone interested in USB-C docks, here is a reputable review of several types. I had no idea how expensive some of these are.

Any word on colour options being finalised for production?

I can confirm that black will be one of the colors available, but I can not deny or confirm any other color options at this moment.

Thanks for the warning, Den! :+1:
I’ve been worried about this ever since I first saw at the driver PCB photos. Especially, because I plan to use NCR18650GA (semi-)flat-top cells.
What is your opinion about simply removing the pot? IIRC, it was mentioned earlier, that currently it does not have any real use (it could act as a current limiter for an optional locator LED, which is not mounted by default).
It could be desoldered as a DIY “mod” by the users who want to use flat-tops, OR it could be omitted to begin with (i.e. not mounted in the factory) in future batches.

I believe that is the long term plan, but I’m also guessing the next batch (in process) will still have it.

I’ve had feedback that the Sanyo NCR18650GA gets close to, but does not touch the trimmer.
As I get more feedback or direct information I will share.

The trim-pot resistor at this time is dormant, and it could be possible to remove it if you wish. as it was a feature added for modders, it has been discussed by the team and its likely it will be relocated in the future lots.

I removed the trim pot on my LT1 with a small flat blade screw driver. Warning: Do not attempt this at home. :smiley:

First just the screw part of the trim pot, but a post was still sticking up.

So I used the screw driver to remove the pot completely, a bit of clean up with some side cutters.
No concern now with my laptop pull batteries somehow shorting on the trim pot.

Note amishbill’s rolled up cheat sheet between the cells. :+1:

Wow, that was pretty brutal. Poor trim-pot! :smiley:

Whats that on top of your cells?

Looks like the tabs you find on cells from commercial battery packs.

I guess they were salvaged from a battery pack (laptop battery, etc). What you see on top of the cells seem to be the remainders of the metal tabs that used to connect the cells in the pack together. They are now cut and folded to act as makeshift “button tops”. Neat trick.

I tested a number of different flat top 18650’s to see if the trim pot was an issue but none of them made contact with the trim pot. So perhaps it’s a matter of manufacturing tolerance that’s causing contact with some of the LT’s?

Man, just got a big “ah ha” moment. I’ve been pulling off the soldered tabs on my laptop pulls, then scraping pliers over them to flatten down the sharp bits. Doing what you did, simply clipping and leaving the main tab, makes perfect sense. I feel so… stupid. :disappointed:
