Thats awesome! DTR was kind enough to add on a contact board to my diode order but ill still need one of those springs. Thanks!

No problem :)

I would order them now, but have no idea how long of a spring to get and will have to wait until I get my host :/

Probably an inch long spring would do it. Actually a little less than an inch but if it sn't too stiff of a spring an inch would be good.

Re: Presale - The Cypreus II - 1x18650/2x18350 - A Copper Laser host by Sinner

Thank you guys for the links, wbs sorry i missed your orings hope it wasnt much inconvenience.

I already have a bunch of 17mm boards, springs and o-rings for this host, I'm also making some changes on the tailcap mechanism so it can attach/detach with ease.

The length of the host does need to reduce , I calculated 7mm excess of battery length, but that shouldnot be a problem if you are using 2x18350's.

While I'm at it, I was also thinking to make the length in such a way the battery connects to both contacts via solid/direct contact (Spring-free zone), Thoughts?

I feel as though it could only be made spring-free for the largest variation of 18650's. There is at most a 5mm difference between the different cell brands according to this, so I would say have enough room for a 70mm battery/batteries (18350s seem to go to up to 36mm, so about 72mm for standard?)

To be honest I would keep the extra length. There is nothing worse than building with an 18650 host only to find that 2 x 16340's and especially 2 x 18350's wont fit. Choosing between having to partially screw the tail cap on, or just adding a spring?:thinking:...I know which Id choose :beer:

Re: Presale - The Cypreus II - 1x18650/2x18350 - A Copper Laser host by Sinner

Yes indeed, Thanks for the suggestions guys. I just finished the final design with some changes that would greatly improve the overall build. Im including contact boards, springs and o-rings so everyone doesnt have to get them individually, Tailcap will be slightly different and more accessible, driver holes will be bigger and battery barrel will be adjusted to optimal fit. Production starts in a week so presale will be ending shortly after.

Can't wait to start my build I hope i'll have my diodes soon, thanks to petters, and wbs for reviewing the host before the batch, and everyone else for their input, Can't wait to see what this beast can do :eg:

:beer:

Hi Sinner. Sorry for bothering You, but if the host will be better made than the first release, with contact board, springs, o-rings, less aesthetical imperfections and so on, I wish to preorder surely a piece! But I'm undecided between the standard or the XL version, for both aesthetical and/or balancing motive. Can You post a shoot for the XL version?

Definitely interested in a Standard (1x18650) but need some info/advice first.

I'd like to make it into a 445 at 2.5-3W+. I know the one battery wouldn't last long but that's okay, I have spares. The all copper construction should give a decent duty cycle, too.

How much to kit the whole thing and I can assemble it? Do you have the parts or can you help coordinate with a fellow forum member to make it happen?

Great design, really a work of art.

I certainly have the necessary skills to make the XL look proportionate, the last thing I want is to offer an ugly looking host, I believe i still have to make one or so I've heard. :beer:

Thanks Jm007, the standard version also houses 2x18350 batteries which are more commonly used. I like to keep them compact as possible so there is no inconvenience esp when you can't fit it in the pocket.

I'll be happy to offer a completed build, just send me a pm and I'll work out the details for you.

:thanks:

Hi Sinner.
Ok, I trust in You! If You maintain the proportions and all the nice upgrades, please note me for an XL version, this time for sure !!:thanks::beer:

Re: Presale - The Cypreus II - 1x18650/2x18350 - A Copper Laser host by Sinner

A litte question for the expert guys: the purpose to use 2x18650 cells is to have more playing runtime, right? But to have more AMP, the cells could be put in parallel mode, not in series (so, positive with positive, and negative with negative, not positive with negative).
Well, in the XL configuration the batteries will be made in series, so the voltage will be about 8V, but the amp rests the same. So, what is the advantage to have more voltage and the same current? I think the driver will dissipate the extra voltage for nothing, and so generate unwanted heat :thinking:

Re: Presale - The Cypreus II - 1x18650/2x18350 - A Copper Laser host by Sinner

You might be missing a few necessary points in your question but Im going to assume you're generally asking for the 445nm's or 9mm diode to be more specific.

Diode's Forward Voltage = 5.1V (at 2.4Amps)

It is easier to use 8.4V supply and step-down the voltage using a buck driver.

The buck drivers such as the X-drives convert the excess voltage into amps and do so rather efficiently without producing excessive heat. i.e: The Amp draw from the batteries at 8.4V will be 1.6-1.8Amps in order to provide the diode with 5.1V @2.4Amps.

Boosting from a 4.2V (parallel batteries?) is rather a different ball park, back to basics maybe?

That is a good explanation and great info. +3
