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

v2.0 designed, sleep over it and see if any errors accured

updates:

  • Power bank stuff removed

+ TP5100 2A charge chip installed
added on battery side a solder pad to switch between 0.75 and 1.5A
added + and chrg and full pads for Charge light indication

+ AMCs can now individually added or removed by pads on the battery side
3 AMCs per channel fixed up to 7 can be unlocked by bridging the solder pads with solder blob

That design i like! :slight_smile:

Yep, that’s nice work.

May I request that 0.75A charging be the default, to minimise the chance of crashing a small solar panel?

I’m sorry to see the powerbank function go, but I’m still planning to buy at least one of these. I’ll decide what to do next once I’ve been able to play with the first one :slight_smile:

for first version Powerbank got removed installing a simple charge board, then the preassembled charge boards were too big to reflow them onto the driver,
so it went on it as parts at least so we can control the quality of the used parts

default will be 0.75A

from the space also 0.5A, 1A and 1.5A would fit with 2 solder areas and 3 shunts, but I think 2 are well enough

No PB and 1.5A charger , great news! Is there any info about Micro or Type-C will be used?

I ordered one I need another one for a total of 2

Interested, please add.

If cost allows it we will try to go with the new type-c plug interface, as long as it don’t drive the cost per unit up to much.

This light is going to make someone a ton of money. I hope you folks working on it have watched out for your financial interests.

So we got the driver after long waiting hope the project become real soon.

At least Sofirn is using USB-C charging on the new SP36, so it is not new, they have the source for the parts.

Just my two cents: seems like mini-USB has the advantage of being able to find a cable anywhere.

Two cents more: I wish there was a place to store the changing cable in/on the lantern. harder to loose it, one less point of failure.

I have you down for two presently, numbers 952 and 1052 on the interest list. I will leave it like that unless you tell me you want a third.

It may for the manufacturer, but as for me it’s costing me money to help get it developed, but i don’t care about making money in this case, i just want to develop & bring a good lantern to the market where such a needed good quality & well designed light has been unavailable up until now.

I guess this depends on where you are in the world. Here in the US, Mini-USB is nearly impossible to find anymore. Micro is widespread, and USB-C is quickly taking over. Within a few years C will have taken hold and micro will start to become harder to find.

Wow. Good job Lexel. Some of us have long ago made an offer to help pay for prototype building if needed. As far as myself, the offer still stands. I know you already built the first prototype, and I’m assuming you will build this one too. Let me know where to donate funds when the time comes.

So far i have taken donations towards the costs of the development & have some to send to Lexel to cover his costs too. Maybe i should start a list somewhere?

Why don’t you use kickstarter? there is a lot of successful shitty lantern projects (like here, here and here) i don’t see why a good lantern like this would fail

you just need a cool looking video presentation with nice a music and you’re done :cowboy_hat_face:

Oh not Kickstarter, not for now anyway.

Maybe for the second version of the lantern, but not the first.

The 1st one is the basis for a beast of a lantern.

We may plan to incorporate boost drivers for the 2nd lantern, USB charging/outputs, etc.

Now that would require a large investment, but would work on Kickstarter since we would only need the funds, but we already have acquired the full knowledge to make a good lantern.

Very true, for the first version i would like to keep this a project of BLF for the members of BLF to get it started, then one the first production run is done and sales are rolling for the V1, then we can look at that for a more deluxe model.
