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

[trakcon]

Thanks for the explanation, zak. I need to brush up on my electronics. It’s been a while.

And, thank you, again, TK.

People have made dozens of 219b fet triples not sure why the sudden concern with a mid drain battery?

If I recall correctly, the old 219B emitters may have had higher Vf than the more recent ones, so the more recent ones are more prone to turning into smoke.

But mostly, I think it’s just because people are more concerned with general safety now, after reports of some Fireflies lights damaging their 219B emitters.

So… I’ll just make a 219 build for the FW3A firmware. It could either have the FET turned off entirely (max output of ~800 lm), or it could have the FET levels decreased to like 25% or 33% or 50%. Not sure which would be better.

TK. You’re the best! BLF wouldn’t be what it is without ya!

Nice! I’ve got a 219B triple board waiting for my FW3A.

I’ve been tempting fate with 219B emitters in a D4. I have the ramp ceiling turned way down and mostly use it on lower levels, but I’ve run it on turbo for a few seconds a handful of times. :partying_face:

Will the FET % be a compile option, or something you determine during testing? BTW, I’ll gladly send you a 219B sw45k R9080 triple board if you need/want one for your FW3A.

Time to jump…
Please add me to the list for one !

Thanks

I’m interested in one.

I would really like it if the ramp has an indication of when it goes from regulated to hybrid modes like the Emisar D4 standard UI. Or if there’s a pre-defined percentage indication in a leaflet that allows one to adjust the ramp ceiling to max regulated current, leaving turbo for full FET.

Would this be possible?

The FET percent is generally just a hardcoded thing. I’m just not sure yet what percent it should be. I’ll probably put in a few options which can be selected at compile time, and make the default build something relatively safe. I definitely can’t turn down a 219B triple board though; those are hard to get these days.

It’s too late to change the firmware now, but fortunately that function is already included. It has a brief blip in the ramp when it changes power channels.

About the actual ramp shape, those values are in the config file. They’re also in the user manual.

Awesome, thanks ToyKeeper!

Great! PM sent.

Please take me (1690) off the list.

Thanks

Interested in two four, is the “group buy” list still open?

Looks like a perfect EDC.

@clip.

Yes, and as many as you wish.

[mortuus]

have the samples to people been sent out, will we hear anything from them?

@mortuus

The reply today from people in the know was: “Should be tomorrow”

[Martinc5618]

Put me down for one too please.

[MokrySedeS]

Can I call dibs on one more (total of 3) but only with samsung emitters (if they show up eventually)? Would it still be as part of the group buy?
Also, I’d really like to have an option to have the bunny on the switch

How do we get put on the list to order? Do we need to PM someone in particular?

You can declare your intention here on the thread of how many lights you’ll want! When the interest list is updated, you’re name will be on it!
