FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

Hah, no. It has three LEDs in parallel, not a camera. :slight_smile:

So, it effectively acts like a single pixel, and can only sense a single pixel worth of information. It’ll have to talk in blink patterns instead of QR codes. And since the screen can be just about anything, it’ll probably be pretty slow in order to make it compatible with a wide range of devices. DEL modified the circuit a bit to make it work, and figured out a way to somewhat amplify and center the signal to improve sensitivity, but it’ll still be a pretty slow one-directional data transfer.

It’ll probably be useful for people who build and sell lights, since it could eliminate some of the need for reflashing. For example, it might be possible to configure voltage calibration from a phone. But for most people it seems like more of a gimmicky novelty. And it could easily go too far and make the thing brickable, so it would be a bad idea to put it in receive mode at a disco party.

(I’m planning to give it at least some minimal data verification algorithms, so accidental configuration should be unlikely, but it’s not exactly going to crypto-sign and checksum each transaction)

I’ll take one, thanks.

Good day The Miller,

Please put me down for 1 of FW3A flashlight.

Thank you Very much,


Hahaha TK, “my FW3A is acting weird, LVP kicks in at 4V and I have only 1 mode” , all baffled only to discover it was a disco party the night before :smiley:

Will update list later :wink:

Please add me in for one piece. Thank you.

Please add me to the list for 1. Thank you :slight_smile:

Yes will do!
Dang overdue again

I’m in for 1. Thank you.

Interested in one, thanks.

Oopsie now even more overdue
Will do it soon, updating the list that is :slight_smile:

Please put me down for a second one. Thanks!

Hi The Miller, I must be asleep at the wheel, could I get on this list also…? Please
Beautiful light with amazing design features, thank you…

Edit: 2 perhaps

So I’ve been wondering (and I can’t seem to find it in the thread using search) but how is the internal tube for the switch’s signal insulated from the main tube?

The tube is anodized inside and out, as is the inner tube. So there are two layers of anodization preventing an electrical circuit. :wink:

Ooh, I like the looks of this light… please put me down for one :slight_smile:

I’m interested in one please.

Please sign me up for one. Thanks

Will update the list later!
need to udate the OP soon anyways!

OP updated with:

Exciting news!
With the active support from Neal we finally found a new partner for our project and the progress is far enough to reveal the name:

The FW3A will be manufactured by Lumintop !!

I don’t want to tell too much but the boring time without progress should finally be over so stay tuned for more updates!

It’s very nice to hear of the progress with a maker and Lumintop is a great one.

I’ll stay tuned to this thread for sure!
