Talk about future projects and donation topic

If someone happens to be interested in discussing any particular project from this thread, they are welcome to start a new thread to discuss that project in more depth. Otherwise, I think this thread is serving its purpose, and a poll is probably unnecessary at the moment. Then again, if you want a poll to be started, you’re welcome to do that as well, I’m sure. :wink:

yes no poll, a project comes when it comes
I was really set todo the Q16 but then the QT/ST came along
It is now waiting to see how Thorfire actually did before deciding on how to proceed.

The lantern is a long running DBSAR project an I have been feeling guilty about the Q8 taking lots of attention from it, so that is his thing, I just try to get it going.

The Q16 needs so much testing and behind the scenes there is talk about moving to a MCUs with more options, ideal for the Q16

Then all of a sudden Lumintop also made progress on the FW3a
So now I am not going to start a new thing.
It seems logical to work on the ST/QT soon, it is a clear defined project making a nice set with the Q8 and using a lot of the same parts, so it is clear what we want.

Tiny drivers, for Q4/Q2 and TKs mini 16340 light require a small MCU too.

So it all makes sense (well to me)
and the braindstorming is just awesome and who knows where it might lead to.

Ah and I am trying to get some sort of database for open Source CADs to use going, this would make it a lot easier for another team to kick off and make things that Lego with the rest.

QT π

Hahaha this MUST be printed on the driver silk for sure :smiley:

:smiley:

I have no idea if this makes sense, but how about a headlight with a strip lens?
Here, a rough sketch of 18350 light with 5-6 XP-sized LEDs and Khatod pl1629. Size roughly 35x40mm.

If you rotate the LEDs so they’re in front instead of above, a similar headlamp already exists:

It’s similar, but not really.
First, it’s 18650, so more bulky. For this reason it also needs a 2-strap headband adding to the bulk.
And it has only one white LED, which is less efficient. 6*XP-L2 V6 does 700 lm @ 200+ lm/W. Add a boost driver and such light doubles the sustained output of a 1-led + linear one.

Have you seen my contest light thread from last year? I made a light bar of sorts, using XP-E2 mounted on a board I designed myself. That board could be tweaked a little to make your desired project. I would actually love to see something like this made by a “real” manufacturer as it could be a really popular style if done right.

Interesting, thanks!
For the reference, here’s the thread:

As to the Q8-based thrower, here’s a nice idea for cost cuts from Astrolux. Though the light with 18350 tube looks so cute that I’d probably take it.

What about a headlamp with 2 LEDs driven at low current for efficiency that uses a 20700/21700 battery? More capacity than 18650 and more efficient led setup should result in pretty long runtimes with the lower modes en a very high (but short!) Turbo output possible.

Possible led choice would be sst40.

I’d rather have a lightweight 18350 based headlamp and bring a few spare batteries when the runtime is really needed. If you really depend on it, it even makes sense to bring two headlamps.

*I would love to have to have a lantern head that would work with the Q8-lego system. I made a diffuser out of a translucent bottle that works well with the Q8, but I am sure that a dedicated lantern head would be much better. USB charging and power bank function would be amazing. I wish that the Q8 had USB charging to make it easier to give them as gift’s to non-flashlight crazed family members.

Yes the BLF lantern of DBSAR ideally should be ready before summer 2018 right :wink:

Has anyone made drawings of what the lantern might look like?

There is a whole topic about it, DBSAR made one based on an SRK.
Pics in OP
And a general idea here

It would be interesting to see a zoomie built around this optic:

and some small, powerful LED. Oslon black maybe? Not very efficient, but I see nothing better…

Please can you show something about it without my phone getting very unhappy for being bounced to a doc?

A zoom lens that is:

  • 7-emitter
  • 39.15 mm diameter
  • 5.1 mm height (+0.2 mm distance from the emitter)
