CK's 7th annual BLF/O-L contest entry [modded light category]

Well after complaining about not having enough time I decided if I got time to complain I got time to work on my project!

I got this Zanflare T1 lantern in the original group buy and despite DBSAR’s hatred of it I actually liked it, right up till it broke… Solder bridge on the driver made it so it wouldn’t shut off and even after cleaning up the offending poor joint it was still not shutting off so I shelved it for about a year. Fast forward to now, the plan is for a custom direct fit replacement driver similar feature wise to the BLF LT1 driver (with a little extra surprise or two CK style)

Plans are:
3× 7135 per channel (even though every individual led on the strip has its own set resistor I’d still like to limit it to not greater than ~1A per channel as it can pull more than that from a full cell)
Control of the red emitters via anduril aux channel.
RETAIN TOUCH CONTROL (very highest priority)
Retain built in charging and potentially upgrade it to battery bank functionality (USB out being lowest priority of the project).

A few hiccups right off the bat:
It was super hard to open, silicone glue EVERYWHERE! Also some touch sensor iC’s allow you to choose the output polarity based on which legs of the iC you bridge, not this one, it’s a high switch signal only and the chip is unmarked. Solution- use a transistor to invert the signal for the Attiny.
Both issues tested & solved!

As of now the led driving and touch switching circuit is designed and I’ve got the board outlined, just need to start component layout and research / decide on / integrate the charger and or power bank parts.

I like this project cause the light it’s self is built, just need to do the [pretty in depth] driver and I can do that in small bits of free time with just my computer without firing up my physical modding tools.

Anyway this is where I’m at for now, I’ll update as work progresses. Thanks for looking!

Nice. Smile
I don’t have this lantern but I’m not its hater either.

Are those 2835 LEDs?
It may be too late for the contest but a couple of days ago I stumbled upon this.

I love it when you speak Chinese Cereal_killer. Some of the pictures I understand.
Love your work and glad there is a modded light making a showing. Thumbs Up

Ok guys I need help already! After 35min of googling I’m unable to source a battery charger / power bank module which has full source/sink capability on a single port. They all have stand alone input and output ports.

I did find a application specific uC from ON Semi which supports any combination of source / sink ports including single [type C] port (as well as PD and every other feature you could even dream up) but it requires FW and lots of work I’m unable to even learn to do and that’s getting to far into it, I need a turn key module I can take apart and trace out to include on my board.
I can always fall back on the good old tp4056 or possible add a dedicated type A output somewhere but I’d really like that powerbank function from a single 2 way USB C port.

Ask Lexel.

ADDED:
Or tear down some flashlight-powerbank or cell-powerbank that has a single port.
You can find quite a few flashlights here:

As to cells, Acebeam and Folomov have cell-powerbanks.
ADDED:
Folomov cell is probably the cheapest of these options.

More:
https://wholesaler.alibaba.com/product-detail/Personalized-Electrical-Ci... claims to have that.
Though I did image search for the 2 boards that they showed – and none is a powerbank. One is a simple buck and the other is a simple boost.

Big and expensive but maybe it will be useful?

EDIT: looks like it needs 4S cells. Sad

Stick an echo dot in the bottom! Silly voice controlled lamp/brightness, that can also tell when to get up! (and give the kids hours of entertainment asking for fart sounds Facepalm )
Seriously though, this is looking good!

I've found "this":https://www.ebay.com/i/172769051983?chn=ps&norover=1&mkevt=1&mkrid=711-1... which claims it has a bi-directional type c port but doesn't do PD on it (only QC3.0 from the type A output).

 

Anyone know anything about it? I wouldn't mind giving up qc/PD in favor of the bi-directional port if it's true that the type C port is in/out capable (could probably also leave some other parts off it for space savings if I gave up PD) but I'm not sure I trust the description.
