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


have u contacted anyone from Sofirn about this? Curious here.

974 on the list, just got my Amazon Au code - Estimated delivery: Dec 17, 2019 - Jan 9, 2020

I’m not sure if that is even an option, is it?

From all I have read on this thread, I thought all I can do is to sit and wait till something shows up in a PM.

Ordered mine, looking forward to it. I also bought one lt1 with batts during 11.11. sofirn promotion. Hope I can get at least one before Christmas :). Thanks the BLF team.

Sofirn has promised that everyone on the interest list will be able buy the LT at the group price. Since they are the ones handling the notification it’s impossible to know where they are. All I can say is to try and be patient as production is ramping up.

It uses attiny85, with 8K of space. If there is ever a LT2, I assume it’ll probably use attiny1634 instead, to provide more pins and more space.

Most of the firmware info in other threads is accurate for the LT1, and some of those threads are linked from the README in the firmware repository. There’s also a fairly recent guide for reflashing the Emisar D4v2, which is mostly relevant. The main differences here are just a matter of how to physically access the control chip.

The short version is:

  1. Get a usbasp device, a ribbon cable, and either a SOIC8 clip or a pogo pin adapter.
  2. Install some free software.
  3. Physically attach the adapter, and run a command on a computer or phone.

It can be a lot of fun to dive in and modify how the light works, so I definitely recommend it for anyone who likes to tinker.

SOOOOOOOO impressed with the run time, I know it’s 4 high capacity cells only moderately running the LEDs but even still, with all these pocket rockets it’s kinda a nice change

Can Hank’s flashing kit for the D4v2 be used or will a different pogo pin adapter style is required?

Received code and ordered from Amazon today.
I was just over 1000 on the list. 1008, I believe.

I have mine programmed for 8 steps between level 10 and 150, and unless I want “a lot of light” a leave it at level 30. 71mA current draw, not high drain batteries so 10,000 mAhr capacity. That translates to 140 hrs. Level 3 is 200mAhr, or 50 hrs. If you want to light up the world, I’m using 5 channels (stock) max is 1.8A, or roughly 5 hours on turbo. Higher capacity cells would get you more much closer to 8.

10-4! :slight_smile:

After a couple PMs back and forth with Sofirn it sounds like they are only sending out one code per person. Once everyone has received one code then they will send out codes to people that had more than one light reserved. At least that’s how I interpreted their response.

That’s how Batch 1 was being handled. They wanted the lanterns to be in as many different hands as possible as quickly as possible. It makes a bit of sense to keep doing it that way, at least until everyone on the GB list has had a chance to get one.

I received in code (initial batch) to buy from Amazon but it is complex to buy it there.
I hope to buy it when it is available on ebay (if possible a “021 Blaze-Orange”), it is much easier.

Contrary to some accusations, I am not dismissive of folks like you who have seemingly been “skipped”. If there’s nothing wrong with your account’s PM settings, then you should have already had an LT1 in your country or in your hands :frowning: . I would contact Sofirn, perhaps by sending a PM to Barry or something.

I want to thank Barry for posting useful updates and information about the Group Buy, but someone should also be responding to individuals like yourself who have neither a PM nor any clue why not. I’m not expecting perfection, but something is amiss when #900 lanterns are being shipped while a few #9 or #93 buyers haven’t heard anything at all.

Communication is the key and if Sofirn believes that the member was sent a PM, then they could post a response in this thread to let the member know that there’s a problem and that it may not be Sofirn’s fault.

I have no doubt that you will get eventually your lanterns at the Group Buy price, but you and the others in your situation deserve some attention from Sofirn so that, at the very least, you would know what happened and what they plan to do about it.

People who demand to receive their LT1’s before Christmas when no such promise was ever made are not at all the same as patient listees at low digits who simply want to know why they have received no communications at all while folks close to the #1000 mark are placing orders. This situation would have been unlikely if we were using the planned, BLF-operated PM system.

I’m new staff of sofirn, Lan Lee who just graduated from college months ago. People who are in 1-1076 of the list have got code, if not, please contact me to check out. Also I am looking back to the list to see anyone was neglected. I’m trying to be better. Thank you for understanding.

I have checked sofirn account messages. A single-used code was sent to you in the beginning of Nov. But you asked for 10 units.

I am sorry to tell you, for now, you can only buy 1 unit. You will need to wait to buy the rest 9 units.

To all BLFers, I apologize if sofirn account didn’t do a great job communicating. Because new staff named Lan Lee, who is a young girl graduated months ago, is using this account. I appreciate your understanding.

Ms. Lee,

Welcome to BLF!

Some of us may grumble when we get anxious about a light, but most of us are friendly.

Welcome to the Forum Lan and Congrats on Graduating :beer: …… Good Luck, youve got a tough job ahead

Got my 1st code today for one without battery’s, my number is 1037 ordered thru Amazon it was easy and simple shows arriving December 24 - January 22
