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

I think there could be some users for 8*18650 LT1.

Camping use some sort of beacon is helpful for markers, checkpoints, emergency, car breakdown all sorts of reasons would be my view.

Bike flasher could probably be dropped from a lantern? yet to see anyone with a Q8 on their handelbars let alone this format and size :wink:

I like the aircraft marker timing’s - very cool :sunglasses:

Agree last production sample is a wise move - I have an Astorlux S42 on my shelf that crushes its cells that will support this theory!

I’m in for 2 LT1’s!

im #1399 on the list but please add another 1 for me

I’ve been following this for a year and would love to see the lantern used for 2019. Please put me down for one. Thanks for the hard work in design and testing.

I recognize the big peaks and valleys from the older version, the tighter ocillations to replace the big peaks in the newer one look like they’ll be nice. Even better!

The S42’s problem wasn’t a matter of BLF not having any production samples. BLF wasn’t even involved. It looked from the outside like the S42 simply wasn’t tested at all. It couldn’t even turn on, since the batteries it was designed for wouldn’t fit inside. And that was only the beginning of its problems.

It was such a big failure that Astrolux made some huge changes in how the company operates, and insisted on getting people from BLF involved in the next model.

Anyway, the BLF Lantern is nothing like that. TBH, I would be pretty happy with it even if the production model was exactly like the prototype. The only major things I want to change about it are to give it newer firmware. I didn’t even try to get it calibrated correctly before a prototype arrived, so the proto firmware is definitely a bit out of tune. But I have most of the necessary changes done now, and am just finishing up a few final things.

Damn, put me down for two more. I’ve started camping with friends more and I don’t want to share mine!

Please put me down for another LT1.

Interested

Interested in 2 please, thanks!

I’ll be happy to see these in the national parks this camping season.

I’m in for one!

Thanks for the solar testing, Den. :+1:

I have that same 10 Watt ECEEN panel and have been quite pleased with it.

Sounds like it’ll get along great with the LT1 on camping trips. :slight_smile:

I do really like its efficiency and size, also its one of the few good solar chargers that has a built in “charge reset circuit mode” every couple minutes. ( meaning if a cloud passes over & voltage drops, it automatically will reset the charging shutdown feature in most Apple products like Iphones & IPads to they can continue charging.

I was just using S42 as an example of shipping a product before you made production samples and tested, could have used a toaster where the toast doesn’t fit, not suggesting any BLF involvement.

Glad to hear that, but having ordered two (one as a gift) it just put me off completely any Astrolux product, I have not looked since at one of their products.

I think with this one I need to learn how to flash the firmware so I can put your latest on, is there a post with the final driver details in? I assume this picture in the first post is current?

I saw a thread on programming on a “key” but I don’t see a header on this PCB, would you need to clip to the chip directly? (I am ploughing through the link in your signature for instructions at the moment in an attempt to RTFM)

EDIT: I take it back, the base of the board has a row of 4 pads inside the ring for the battery tube contact, is that the programming header?

EDIT2: Right next to the word “programming” :person_facepalming:

Off to find that thread on the programming board/key…

Looks like this thread talks about the key needed to program:

Along with the programmer from the README:
http://bazaar.launchpad.net/~toykeeper/flashlight-firmware/trunk/view/head:/README

There is some “discussion” around a standard - can anyone advise if that oshpark key is suitable for the LT1 driver?

Edit: Or is it this one? https://budgetlightforum.com/t/-/72815?page=2 :question:

No, it is Lexels programming Key: BLF driver programming key v3.2 launched on Oshpark

Thanks for confirming it was the second option.

Ouch… I bet somebody got a serious black mark for that little oversight…. :smiley: … :person_facepalming:
