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

Hi does anyone updated interest list last time?

Well said.

I wanted to say something like this last night, but couldn’t find a good way to put it, so I set it aside and went to bed. I’m glad you’ve said it for me :slight_smile:

Has the lantern Andúril one setting for both ramps or can we have different tints for the smooth ramp and the stepped ramp?

So far, it has a single tint value which applies to all modes and can be changed at any time.

I haven’t even thought about making the tint change based on which ramp it’s using. The main fancy bit I thought about doing, perhaps, is dedicating one of the 256 tint values to “automatic” — warmer at low levels and cooler at high levels. In particular, it might be a nice thing to do in candle mode. But I haven’t tried that so I don’t know if it would be worthwhile.

Benidin added to interest list for a third lantern at number 971. Your other two are at 453 and 454. These numbers are not really important, and will likely go away soon. huey18 is generating a bot to automate this list keeping. Until it is done I am doing it manually.

I still have not sent an updated interest list. You can see the interest list anytime you like. Will likely send an updated list to DBSAR in the next couple days.

I sent an updated interest list to DBSAR today, so if you don’t like looking at the links above, I imagine in a day or two he will update the interest list in the first thread post.

so when will these be available??? surely SOON would be better given that autumn and winter are JUST round the corner!!!

I’m really hoping these are available during this seasons fall/early winter camping season! Summer camping is a no-go here. Too humid. Good luck sleeping in 85+ weather with 98% RH.

so finally added thermal viases, 1A and 1W is pretty much fine as it was, but if people want to go higher they need more cooling on the MOSFETs
also rearranged the common ground for the OPAs and MCU

That’s a nice looking driver board. Thanks for your work, Lexel. I hope your hand is healing nicely.

Looking good! Any thoughts or ideas on what the maximum “factory” amp draw on high is set? assuming it will depend on the sense-resistor ohm value? Also the button LED still has ability to change or be programmed from TK’s UI?

Oh look, another Wagon.
Please put me down for 2.

Thanks!

If “simple” version would be I am in. Simple , efficient, durable. That is I really need, no powerbank, no color change and so on.

The original concept for this project was just that. single color, 4 modes, basic built in 1 am charging, (as i built the V1 of the first lantern.

I have to agree on this. Especially if it falls under the 39$ category.

4000k, over 90CRI, no color change, no need of powerbank. Just plain eyecandy lighting with longish runtime. One moonlight, one superlow, one low, one medium, one high. Nothing more, nothing less.

Preferably in silver color so scratches won’t show up and Nichia Optisolis leds with R9 over 90, and CRI over 95. which is a led that we apparently forgot about. LED test / review - Nichia Optisolis 3000 / 5000 K - ultra high light quality, even with high performance in mid-power class

YOU need 4000K.
I want 3000K.
The next one hates WW and opt for 5000K.

Sofirn will sell probably only one lamp without tint ramping from the three above.
It makes a lot of sense to have tint ramping.

If you want a cheap one (with a few flaws) you can search BLF for the Zanflare T1.
Maukka did a short test here: Ended - #477 by maukka

T1 is excellent, but it does not have 95+ CRI. And a LED swap is notoriously difficult.

Otherwise it would be extremely useful.

It can be 3000K or 4000K, or 5000K. It does not make a difference as long as the CRI is above 95 and R9 is above 90. Try it, you will see.

And I like this. I don’t need even charger, but IPx8

I can reflow leds easily. So I like 4000K, but can agree with any CCT.
T1 is not simple , not efficient, and not durable. I already have butch of such lamps.
It is worth investigate interest to simple version. And may be launch it after main project. This allows not to split the efforts, and second version would be born much faster.

The beauty of this UI is that you can have those modes, and I can have ramping. 3000K is mandatory for a lantern, and with temp changing we can have that and 5000K, and everything in between.

Yes, exactly. Especially since it’s pretty much already implemented.

That’s why the temp ramping is so wonderful, no need for LED swaps (unless you’re wrong and prefer cool white, lol).

I still think that LED swaps will be made even on the Full version, because the Samsung LEDs are inferior to Nichia Optisolis.
