This is a really nice little green build in the awesome UltraFire C3 Stainless Steel host!

Now, the host has been shown by others, but I have made my own custom modifications and unique design for it to fit a CR2 battery instead of the stock AA size. (machined inside the back end of the host to fit the larger diameter battery)

My personal feeling, is that since it is a unique design, even using a different battery supply, there is no 'copying' here...

But since I have seen LikeitBright using this host, I asked him if it bothered him and he told me that he had no problem at all. Because it is a completely different design.

So the main determining factor, is to be able to get the 'shorter' size modules as shown in my pictures below.

Update: See the information at the bottom of this first post to see how easily a DX module will fit this host! You can get a pretty good powered DX module! And they ship to the U.S. now. They are under 'DIY Parts & Tools':
DealExtreme: $46.81 200mW 532nm Green Laser Module (3V 11.9mm)

The host is the Stainless Steel UltraFire C3. DX sku 11133:
DealExtreme: $18.90 UltraFire C3 Stainless Steel Cree P4 LED Flashlight (AA/14500)

My last two O-like 50mW modules were a little shorter than the ones that I got before, so that is what makes this doable. (see the measurements in my pictures)

Here are the pictures that show the modifications...










It is a very heavy and solid design with good heatsinking for the module. I have e-mailed Susie to try to find out about the availability of this size module. And if they are also available in 100mW's as well.

This design offers the option of using CR2 primaries, or RCR2 rechargeable batteries.

I am using a CR2 primary and am very happy with the results, so I will not need to push the module with the slightly higher voltage that the rechargeable battery has.




With a CR2 Primary battery:
73mW's right away...
65mW's after 15 seconds,
62mW's at 30 seconds,
61mW's at 45 seconds,
61mW's at 1 minute.




Here is is next to my new Key Chain CR2...

Got to love it!

About the module modification, it is not hard. It is nice if you have a lathe, but if your careful, you can even use a hack saw!






Pricing:

You need to have a module that can be modified and sized between 47mm's and 49mm's to fit this kit. (see picture above)

If we can get these modules, I can do the modifications on the host barrel, tail switch spring, and make the custom heatsink.

The kit would include:

* The Host (machined and modified to fit the CR2 battery)
* The Custom heatsink with set screw. (you will need a 1.5mm Allen wrench for the set screw)

$59 dollars plus $6 dollars shipping.

Shipping: Out of U.S. buyer assumes responsibility at that price. It should not be a problem though... (I would mark the package as a gift, with a description of 'LED Flashlight' with a low value of $15)

The module and battery will not be included in the kit...






Update!

I finally got my DX 200mW module.

The module is under powered at about 105mW's, but still, it's a nice fit into this great stainless steel host!

Here's how...







The red wire gets cut off, and the black wire gets cut short as well (just leave enough solder there to make contact to the battery negative), and the switch gets by-passed.

Pretty easy! Just make sure your DX module is the same size as shown in the pictures, and let me know when you order the kit so that I can drill the heatsink through at the front, and machine out an AixiZ focus ring for you.

No extra charge for this work if you want this kit!

DUDE JAY JUST STOP! ahah just kidding....JAY strikes again!..
gettin me one of these soon
amazing work!

Jay you never cease to amaze. Can't wait to get me one of these

Im getting one first!!!

You beat me to it J... i had a similiar design in mind. involved sawing the module down as well.

Dark

It's a little bit of a pain to machine the barrel to fit the CR2 battery, because it is solid stainless steel.

But it is worth it! This is the perfect little Mini Green host that still has good heatsinking.

The stainless steel is really nice! And as you can see, the assembly is cake...
Jay

Hey, Jay.


Cut it out.

I'm only joking. This looks really, REALLY nice. have you tried to polish the host?

thats an amazing kit.how hard was it to modify the green module to get it to size? any chance of doing the same mod to a 100mw or 150mw or is the 50mw the only one that will fit? sorry im a noob.

Love the feedback!...

Th0ughts, I have not tried to polish it, because it is so nice already! But I could imagine that it would really shine up...




dub599, I am waiting for an answer from Susie (O-like) about the availability of these shorter modules in higher power.

The modules that I have been getting in the past are longer, and would not work for this build. But as far as cutting the brass barrel shorter, that is easy on the lathe. It could even be done with a hack saw I suppose. You just have to be careful not to scratch the lens, or move it either...
Jay

sweet please let me know what susie has to say. im beyond interested in one of these as long as its possible to replicate easily

That looks awesome, I love chrome hosts!

Great work Jay! Nice to see a green mini host. Especially in stainless.

Thanks for the props guys!

Yep... Stainless steel!

Not chrome coated brass like your Micro Chrome is bryce007. Which is nice too, but the SS is bad to the bone! This host is very small for a green with a 'click on / click off' switch. As can be seen in my comparison picture.
Jay

Yea I know, but it is all I can afford at the moment. But I'll be saving up for this one!

I think this design will be a favorite with many! It is really nice...

But the module length is the determining factor. I will let you guys know what's up when I get news from Susie...
Jay

Thanks J!

How do you keep getting these ideas? I love this one, looks pretty sleek !!

SCHWEEEEEEEEET

Jay how much would you charge to cut down an o-like module?
I have a nice host that is 0.8cm too short to fit well

Rob

Well, it's just that when parts get smaller, it makes it possible to build it into a smaller host. Which is the best! (IMO) As long as you can have decent heatsinking.

That's why the FlexDrive is so cool... It is not only tiny, but it can power a blu-ray with a single lithium battery!







robjdixon, It is an easy operation on the lathe...

The only problem, is that I don't want to be responsible for a 'fluke' thing like maybe the lens getting a piece of brass dust on it, or the module getting lost in the mail.

If your willing to take the responsibility for those things, then you can send it to me, and then I will contact you for return shipping and ask for $10 bucks to cover my time and return shipping. Just send me a PM!



Update: Susie says that the 30mW and 50mW modules will be 59.4mm (which should work for this kit if they can be modified to 49mm as shown in my picture), but the O-like higher power modules will be the longer ones. Traveller has told me that Rayfoss has 50mm length modules (which would easily fit by just shortening the spring), so he is checking into that. (and I'll e-mail them as well) It would be nice to get a 100mW (or even higher power) module that is short enough to fit this kit!
Jay

Maybe you won't have to. Jay & I are looking into an alternative source which may be able to supply us (all) with 50mm modules...

Stay tuned...

I own that host and trust me, you don't want to polish it - looks really really great in real life as-is

This is true...

It's so nice, that I don't even want to put a warning label on it! I don't even mind the Logo's on there. That's how nice it is!
Jay

I would really like one but the 150mW o-like modules are 62mm and I don't have the intestinal fortitude to chop the barrel of the module.

-Mike

Yea I'd be scared to. This host and heatsink could be used for a red or blu-ray build right? Using one 14500 and a flex drive or two 14250's and a rkcstr driver? Would that work?

Yes, but it would be a different heatsink set up. I know that this host is already being used by LikeitBright for very nice red and blu-ray builds. (and I think Dark Horse too, but I don't know who was first) So I would not want to copy the design for selling... (I'll use this host for some personal builds though! - it is so sweet)

This green design is completely different from his green design with the same host. My set up even uses a different battery supply. He has told me that because of the completely different design, he has no problem at all with me selling this kit.

Note: Nobody has any patents or anything, but it's just common courtesy to not sell the same design/and host that somebody else came up with, and is already selling...
Jay

You're a good man, Jay Brown!
