MBI Core Ti - (world's thinnest??) Titanium Flashlight Pendant - (work in progress)

[rebelbayou]

A couple of 2016's would suit me just fine. Getting excited about these 2 new lights from TGWNN.

[eai2l]

+1 also flush or recessed.

+1 for blank button.

And with such a small light that little increase in height and width do'nt matter to me

[Burgess]

I would LOVE to use a single CR2032 battery.

[Tixx]

Battery/Led choice and size implications....

Please give me your feedback

In order to use a CR20xx series of battery (eg. CR2012,2016,2025,2032)
we will need to adjust the dimensions slightly...

Now: width 22mm, length 32mm
Proposed: width 24mm, length 35mm

Can you let me know this is ok for everyone?

Thickness will be the same.

If we use a CR16xx series battery, we can keep the current size,
but the CR20xx are much more widely available and provide the option for more brightness without needing more thickness.

A) eg. 2x CR2012 = 2.4mm
B) eg. 2x CR1616 = 3.2mm

With A) we can keep the thickness around 3.5mm~3.6mm (definitely under 4mm)
With B) we would be at roughly 4mm~4.5mm

The current prototype (in the photos) uses 1x CR1616 and is about 3.6mm (with internal room to spare)

Thanks,
tgwnn

I think the proposed length and width would work well!

[Tixx]

I thought I had posted this image already...

The default led in the Core Ti (on the left) is completely hidden,
I've been using slightly different shaped leds, and positioned them to protrude just a little from the bottom.

Actually looks kind of cool, like lit candle wick in your fingers....



blue and pink look really cool too!

Have I posted this?
(I must be doing far too much posting )

I prefer the look of the flush, but beam would be the final consideration.

[PapaLumen]

I agree. By the way, will you be offering it fully polished? Not sure what was decided over the last 6 pages of this thread. Cool looking little thing, will it go on a keychain ok? Also would prefer without the MBI on it..

[kaichu dento]

I prefer the look of the flush, but beam would be the final consideration.

This is exactly what I had intended to post but upon examination of the pics it appears that there is a wide enough cone of light coming from the flush model and since everyone posted in favor of flush, felt pretty confident it would go that way. Nice to see someone voting based with function first, aesthetics second.

[the_guy_with_no_name]

That's a lot of possibilities! I have lights for which I need a reminder card on how to program or the runtimes... Never had one for which I need a reminder card on all the batteries it can take! Me Likes!

Thanks Cataract,

Glad you find it a useful concept

Like kaichu mentioned, very practical thinking

Roger that. Will let you know on final possibilities after "thickness" testing

Yes, polished is still default,
after we make a proto in the new size, planning to "attempt" a stonewash too, though not sure we can get it quite the same as the good looking knives kaichu mentioned,but will take a stab at the finish and see if its possible without totally killing the Core Ti.

As a note, so far the polished versions seem to be holding up very well. The button seems to stay super shiny just from using it all the time.

Its a good point to pick up on!

I will be doing my utmost to get the function right, and then balance the aesthetics to look just perfect with it.

I can't find the quote anymore, but you where wondering what I had in mind with modifying the button. I was thinking to replace the button with a semi-precious stone (which will need hours to shape, but I've got this one :grin After thinking it over, it might be impossible to replace the whole button since stone is very brittle when it's too thin, but it's always possible to modify a button with an opening in the center (perhaps elevated) to insert a stone in there... or maybe a series of very small ones.

Cataract,

Thanks for clarifying, now I understand what you meant.
Not sure if replacing the whole button will work so well but something ontop of the button as you mentioned could work.

The button is pretty much flush with the body of the Core Ti at the moment.

How about a changeable button skin, like a cell phone? Different colors/logos for different occasions,
and one with a setting for Cataract

Originally the button side of the case was on the top (the cover part) of the 2 body pieces.

I had a really tough time positioning the button (without it moving around) when closing the body,
so I told the R&D team to reverse it so that the button side of the case was on the bottom, and the blank side, fits on top of it (kind of as the lid) meaning that the button wouldn't fall out when replacing batteries (much easier).

That may make it a little trickier to replace but still do-able I imagine.

re: skin for the button...
the whole Core Ti is the skin,
just keep the batteries and put a new Core Ti around them

seriously though, extra buttons is possible of course, its the custom shaping part that is costly (mold for this, mold for that) its like everything needs a mold.

Once the new proto is ready (tweaked for the new batteries), I can check on possible button options, so feel free to post if that's something you want.

...and I think I have found "the" led for the Core Ti!

Waiting on a few more details but once that's nailed down, version 1 should be around the corner!

[the_guy_with_no_name]

A quick update to let you know I've been testing battery combinations.

2x CR2012's seems to be perfect! :
A BIG difference in brightness compared to just 1 cell.
You can always use 1x CR2025 if you prefer a little less light.

I have also received feedback from some manufacturers regarding led's and I think we have some good candidates (waiting on samples).
Currently also in discussion about producing a totally CUSTOM made led, from scratch for the Core Ti.
Never thought I'd be getting custom led's created! very exciting stuff!!

Thanks for posting that comparison!
its perfect and a very nicely taken photo too if I may add.

Currently working on the tweaked body to handled the CR20xx series battery's.

I have to say, I've been wearing a proto version since it arrived and without any bias, its the first wearable light, that doesn't stick into my chest (or back) when sleeping, and its very light weight which makes it un-noticeable, easy to wear and proving useful already.

If you are the kind of person who likes having a light with you at all times, you will really appreciate the Core Ti!

My girlfriend really enjoys diamonds, I would much rather buy her a flashlight necklace that looks like a jewel, and something that functions and serves a purpose other than to look good is more my taste. Maybe I can turn her into a flashaolic . I think you got a real winner here, especially if the price is right. I dont think anyone makes anything like this you could be the only one to have this category.

Thanks Expert,

Aiming for the concept of functional jewelry with this and hopefully we can convert a whole new audience into flashaholics, without them even knowing it

Is it definite, that this canNOT fit a CR2032 battery ? ? ?


Just curious -- since that is my prefered battery of choice for this flashlight.

Hi Burgess,

Thanks for checking.

The 2032 will fit inside, just need to be sure that the fit when closed is solid enough (so there are no accidental opens), because its 0.8mm thicker than 2x 2012.
You may end up with a 0.8mm thicker model, thats all.

Will post more of an update in the coming days.

Hey I don't know if you have thought of this or will like it but.........what about a tritium vial slot? people that have this lights on their keys will be able to find them at night. And being worn as a necklace will just add to the cool factor. Just a thought.

Yes, I think someone has mentioned trits also.

It "may" be possible to do a version that could accept one of the smaller tritium vials but will need to check on space after the next prototype is ready. I think the vials would need to be flush with the pendant to avoid breakage and based on the internals, that would put the vials somewhere near the bottom, at either side of the led.
We could possibly laser cut enough of a hole to add them which is the easiest way to do it in small quantities but that would reduce water resistance.
It may be possible to create a beveled space large enough near the bottom, but that also means getting another mold made (and they are very expensive to make).

Yes, I certainly understand the difficulty within the engineering of this, but either way ill buy one if the price is within reason. Trit would just be another selling point. But I guess what you have to ask yourself is it so much of a plus that you would re-design to some extent to except trit for better selling points.

Thanks,
I'll explore the trit option once the next proto's are ready.
perhaps something for a future version.

[the_guy_with_no_name]

Currently working on the updated proto's.

Size will be 24mm x 35mm (2mm longer/wider) and designed optimally for use with 2x CR2012 or 1x CR2025
but should be fine with 2x CR2016, 1x CR2032 (though I need to verify the front/back are not too loose with those).

The angled hole has been implemented nicely.

Led makers have been sooooo.... slow to get back to me.
I guess anything less than 20,000 or even 50,000 units, and they are not overly motivated.
We are making the proto's using a 3mm led and modified 5mm led (which is now a 2mm led).

Additionally, the body of the original proto's were 0.3mm in thickness and we have increased that a little to add strength and durability.
Even though the increase is slight, the workshop is having a tough time though because it seems the titanium is so hard, its breaking the mold and their equipment.

I went out and bought a range of necklaces as well.
Leather, small ballchain, silver & SS of various designs.

Planning to send out the first mail out perhaps over the weekend and I hope to take some photos of the various chains to give you somewhat of an idea of what it may look like (if I can take decent enough photos..)
