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

Just one, it seems to be a mistke. Thanks a lot

Wow mixing the Nichia 219c tints would be so awesome! I would love to see that in action and would be nice if we have the option to add money for custom features similar to how the Emisar D4s are sold.

I don’t expect tint-mixing to happen. It’s not really in the Overton window yet, and it would mean tripling Lumintop’s investment. Instead of a single reel of 3000 emitters (1000 lights), it would mean committing to three reels of 3000 each, or 3000 total lights.

Even if Lumintop wanted to make three times as many units, they’d probably just offer it in three different flavors.

You could create a ‘Team account’, as was done in the BLT GT thread; and ask sb to change the original post ownership from the miller to the ‘Team account’. That way the OP (original post) could be updated with the needed information.

It worked well in the GT thread once it was done.

I’m in for two

Please count me in for 1. Thanks.

I guess you should be “promoted” to a team member!!!
Thanks for the work done so far pepinfaxera :+1:

Agreed! Thanks pepinfaxera :+1:

Pero, estas haciendo un trabajo muy bueno y de gran valor para lo seguimiento de este proyecto :wink: Gracias!!

(But, you are making a very good and valuable work to follow this project! Thank you!)

Put me down for one plz

In for (2)! :smiley:

EDIT: Let’s make it an even (2)… hehe

I’ll take one as well…Thanks BLF and all who’ve worked on this design !!!

I am interested.

Forgive me for not going through 75 pages of messages, is there a lumen output approx. on this light? And any idea how long until completion?

Output of FET triples is pretty well established and tends to be between 2000 and 3500 lumens depending on emitters. Last I checked a 219C (90 CRI D240 flux) FET triple, it was about 2500. A low-CRI XP-G3 (or low-CRI 219C for that matter) would be higher.

I made some progress on the firmware…

Candle mode is updated and more realistic now, simulated using six oscillators — three of which modulate the other three like an old analog synthesizer. The result looks similar to a candle with periodic disturbances in the air.

Fixed a bug in thermal regulation and LVP, which were both running about 1000X faster than intended. So, those work again.

Thermal regulation uses 512 internal steps while searching for a sustainable level, which makes the adjustments invisible by eye. A lux meter is needed to see what it’s doing.

Made thermal adjustment speed change depending on how far it needs to go. It can happen anywhere from 1 step every 8 seconds to 8 steps per second.

Added the ability to calibrate the thermal sensor to room temperature. This should help with the issues related to different attiny85 units disagreeing on how warm it is.

The UI diagram is updated too:

Very sweet ToyKeeper! Thank you!

Nice TK!! :+1: … Thank you. :slight_smile:

I’m in for a single FW3A.

I’m down for 2. Thanks
