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

The optic nerve pin might also be usable to drive an indicator LED, if the sensing function was sacrificed. I haven’t checked the attiny docs to see if that pin has the relevant functions, but it probably does. And the optical programming stuff hasn’t been written yet.

I’ve kinda been waiting on the second prototype to arrive since I’ll have to mod the light to do any optical programming development on it, and it won’t be usable for non-development purposes any more.

Please put me down for 1!

Please, put me down for one.

kahvitahra should enter and publish how many lights he wants
.
In Interest List, Post # 4 Page 1, it only has one “1” .
2nd cancelled.
.

The right column, not the left column. :slight_smile:

Three posts: Two requests, one cancellation. Total of 1 light. Currently #809 on the list.

Because of the accidental second request, I used kahvitahra as a test case for the code which handles cancellations.

I apologize
My mistake
Now I have to edit Post 2128 and 2129 Page 71.
Sorry.

OK, TK does it remember the Last Blinky and the Last Strobe ??

What are the default Blinky and Strobe modes ? After a power cycle?

Sounds great.

It remembers the last-used mode in the strobe group. However, the blinkies always start at battcheck.

This can be partially inferred by the arrows from “off” in the diagram, since one points directly to battcheck and the other points only to the strobe group.

Great. i love it

please add 2 more for me for a total of 4. thanks

I’m liking this flashlight even more. I’m interested in getting a second one (my first one is #983).

There is a thread for drilled optics that can fit 3x tritium in your color choice that can serve this purpose. It’s quite a bit more expensive than your suggestion but it also glows with no drain on the battery.

I saw recently that Oveready is using optical programming on their Boss lights. I wonder if that stemmed from discussions on BLF or if they have berm doing it a while. They also use the same optical sensor as a safety feature against their light turning on in your pocket somehow and cooking your leg.

http://lux-rc.com makes their drop ins and they have been doing optical programming for a while, along with some other very advanced features.

Interesting, thanks for pointing that out. I guess I assumed when I saw it discussed here that it hadn’t been done yet.

The Lux-RC people did it first, but I didn’t know they existed until I made my proof of concept last year. When I told people what I did, they asked me if it was like Lux-RC, and I was like “lux who?”

The differences in my implementation are:

  • No optical sensor required.
  • No special MCPCB required.
  • Works with reflector-based lights too, not just TIR.
  • Can’t sense anything while the main emitters are on.

Interested. Please put me down for one.

Interest list updated.

I should be on the list for two, but am only on there for one.

Thanks. It’ll be in the next update.

At some point, I plan to have a script go through every post to train it to recognize requests, and in the process it’ll also add missing post numbers to the list and look for any requests which got missed. Then with the complete data set filled in, I can further tweak the engine to recognize things better.

Request numbers will change, since corrections will go in the order posted instead of the order noticed. It may also be useful to merge the TLF requests into the same list, in chronological order, in case there are any supply limitations (distinct batches) like there have been on some other projects. That will also change the request numbers.
