Sorry to be so ignorant!

Where do I pm them? do they have a presence on this forum?


Look for a title with Sofirn in it, find the id and clic the send pm .

May I ask where you have seen this deal?


A few days ago the price at sofirn shop was $60 ; the price at aliexpress is $57 . Amazon uk sells the lt1 79 pounds with local delivery . Ask them for a discount code or when it would be possible to have one ?

Update everyone, I have been in a bit of a hiatus lately as i was diagnosed with the COVID-19 and became ill for a few weeks, and currently recovered but have a lot on my plate with life’s struggles, financial struggles, job struggles, etc. I do hope to get back to BLF as soon as i can to continue the LT1-Mini project, and future Lantern projects. Thumbs Up

Not sure if anyone noticed the SOS Mode?

Driver Rev. 5.0 is installed.

After Beacon Mode there is the SOS Mode.

Where normaly the Temp Check can be found in Anduril Flashlights.

Right, I should probably add SOS to the lantern’s UI diagram… forgot about that.

Also, apparently I got the timing wrong for SOS. It blinks out “S O S” as three separate letters, using the official timing standards… but it seems that “SOS” is meant to be transmitted as if it were a single letter, with none of the usual pauses between. So I fixed that, but it was only a few days ago.

If anyone wants the updated version, it’s here:

http://toykeeper.net/torches/fsm/anduril.2020-06-02.blf-lantern.hex

It’s a really minor thing though… it just changes from “S O S” to “SOS”.

About the tempcheck mode, there is no thermal regulation on the lantern, so all temperature-related functions have been removed. The reason is because the temperature sensor is nowhere near the LEDs, so it can’t sense the temperature of the parts which matter.


Edit: The UI diagram is updated.

Hi all,

this is an awesome project and I am very happy with the LT1 that I received yesterday. Thanks to all people that were involved in the creation of this fine lantern! I always appreciate the possibility to have a lot of features and being able to customize them, even though it can be a little confusing with just one button. Therefore I created my own small manual for placement in the battery compartment based on the one made by AmishBill, but compiled a little bit differently to fit my needs.

Anyways, I thought maybe it is also useful for others and thus want to share it:

There are some LT1 with old version left. We decide to makes deal for these lantern on our website. You can get old lantern kit with $10 OFF than LT1 new version now.

Besies, we will produce make colored  New LT1 lantern Desert Tan, Green, Orange, Even bare aluminum, you name it when old Lt1 sell out basically. 

 

1.How to distinguish old version from new version?

Thanks for the Deal on the older LT1, a very good deal.

I’m still waiting for the colored versions to come out, as are many of us.

Are we/you going to have a list for the colored versions ????????????

Thanks for the update.

We hope to sell old versions quickly, and start the colored versions soon

 

Now same price on Old version with batteries, and new version without battery.

 

Actually old version of LT1 does not work with TYPEC charger which need to be bought seperately.

 

How many people have that kind of charger?

 

If you don't have that kind of charger, Old version works the same as new version!

 

The shipping fee is more expensive than before the pandemic, maybe the shipping fee will never drop back to where it was.

 

Sofirn may have to increase price a little in the future to keep reasonable profits.

 

This is the time if you want a LT1.

Just got mine yesterday and this lantern is awesome. I will try to get into all the programming sometime today. Also check to see if it has the latest firmware and the pods discussed are connected. I’d love to have a case for it. Won’t be hard to find something that will work.

I wish the button could be illuminated all the time. While the lantern is on the button light is off.
It’s difficult to find the button when the lantern is on.

The button on mine stays on when the lantern is on. When the lantern is at low brightness the button is dim, but it does stay on.

Does anyone know if LT1’s are in stock anywhere in the USA? I’m looking for a quick shipping time if possible. If not, I’ll just order from the Sofirn website. Thanks!

P.S. If anyone has one brand new in the box, that they want to get rid of… send me a PM. Beer

I have a request for someone who has experience and is willing to do circuit board drawings and upload it to Oshpark (as I can not do that)

Here is the LT1 ledboard:

*Outer diameter=60mm
*Central hole=6.3 mm
*Screw holes are 2.8mm (for M2.5 screws) and are 20mm from the middle (or 28mm from each other).
*center of the anti-rotation holes for the plastic cup are 8.5mm from the middle and are 2mmx4mm width/length.

The request is to draw a commonly from Oshpark orderable frp replacement ledboard for 2×20 standard 3030-size midpower leds, so 20xwarm and 20xcool. If the warm and cool leds can be mixed well (as far as the traces allow), the tint mixing of the lantern will profit.

As the midpower leds will receive 100mA per led, I’m pretty sure a metal core board is not needed if you order the board in thin 0.8mm frp and perhaps choose the thicker copper tracing. The board can, like the stock board, be screwed down with some thermal paste in between.

This makes the LT1 suitable for the entire range of available standard midpower leds, including Optisolis, SunLike, and all the others.

Of course if someone dares to have real MCPCB’s for 3030 leds made and sold, that would even be better. But it all starts with the design.

I had a similar idea to this 6 month old post from djozz, and his suggestion is the only post that seems to have turned up in my search.

I just wanted to add that if anybody does this, I’m interested as well – thin FRP or flex PCB from Oshpark, or else an MCPCB in a group buy.

Or perhaps Clemence might be interested? The LH351D’s are pretty good, but I’d love to how the lantern looks with Optisolis or E17A’s in there, and perhaps try a slightly different CCT range.

So is the difference between version 4.3 and 5.0 strictly the USB C-C functionality? Or have there been any minor adjustments to the other functionality?

Given the tube diameter, I’m wondering if a beer cozy might fit on this. It would be a way to change at least part of the color for those who don’t want to wait until September to have a different colored body from black.

USB-C PD functionality like you mentioned, and 0 ohm resistors used to activate the 3/4 and 5 regulators as stock instead of having the pads manually bridged from the factory.

I think it was mentioned as a prior suggestion, but some DIP switches would be really nice in place of the solder bridges, even if they can be bridged using some graphite pencil lead.

@DBSAR Been meaning to get in and thank you for producing this thing. Heard you got the Covid-19 and had some difficulties, I’m hoping you’re ok and things are getting better.

Look mate, this lantern is the biz. Much as I love my old paraffin (kerosene) Tilleys and Vapalux lanterns and the old wick storm lanterns for my camping adventures, they are a faff to deal with. I have a big canvas bell tent and recently had a paraffin spill onto the outside canvas when the pole holding the lamp (luckily unlit) fell onto it.

Your lantern, with the warm/cool and Anduril is perfect for my needs. It’s currently sat beside me indoors in preference to the ceiling lights, and as soon as we can get out for a few nights in the campervan it’ll be getting some proper use. Good work fella Thumbs Up

Do you know what was the rationale behind the “ohm resistors used to activate the 3/4 and 5 regulators as stock instead of having the pads manually bridged from the factory.” A minor adjustment overall for efficiency, or to address a particular issue? I also agree that dip switches can be a very useful way to customize functionality in a more semi-permanent fashion.

OK, good to know — thanks! Might be possible to utilize a neoprene cover for a water bottle, trimmed to fit.

The biggest reason for this (IMHO) was to remove a manual manufacturing step and related QC needs. The originals required the first pads to me manually soldered at the factory. More than one example made it past QC with incorrectly soldered pads. There’s no knowing how many were sent for rework or how much time was spent on this manual process. Adjusting the traces to accept factory placed 0 ohm resistors lets them be placed automatically and consistently like the other components.

I believe it was due to a quality issue, not getting all of the pads 3/4 and 5 soldered correctly (or consistently). This likely had to be done by hand. By installing a 0 ohm resistor, they can just install the part there (like all the others on the board) and reflow the solder paste and make the connection automatically. That’s my suspicion anyway.

Edit: Amishbill beat me to it. by a while . . .

This is probably a strange question, but does anyone know where I could get a few more of the large orange o-rings that come with the LT1? Or even the actual size of the original ones?

I’d like to be able to put one in the groove above the diffuser and another in the groove below it.
