Hey IgorT.
I'm interested in your heatsink/host. The grey one.
Good, that's the Romisen host, some people call it the "Classic", because while i did make several other models, this one was requested in the majority of orders in the past and the present...
That's because it's SMALL, very tiny in fact. Now there are smaller hosts out there, i've had some of my own machined by Jayrob, and they came out GREAT!
But a 6x or even an 8x laser require some heatsinking and that can best be achieved in a laser with some room enough for a good heatsink!
It's in the smallest size that still requires no duty cycle limit!
Altho the 12x will probably have a five minute limit....
Basically, tiny lasers are cool, i'll have a lot of fun putting Jay's CR2 Keychains together, they at least have a heatsink unlike narrower keychain hosts!
But on the other hand, my Jay tiny Keychain with a Nichia at 200mW inside takes like five minutes or more to get noticably warm!
That is also an awesome host! I need to order two more of those!
I have a PHR inside an aixiz module.
I also have 1 phr sled that I can extract. (got 2 after i killed 1st one)
I don't have a diode press tool btw. Pliers worked for me. [/QUOTE]
Pliars? You mean you used two pliars at once to press the diode in the AixiZ module?
That's OK i guess, if done right, BUT you didn't push the diode into the AixiZ to the end....
With AixiZ the diode is not meant to be flush with the top but "under-flush", slightly deeper, this way it also gets better thermal conductivity into the AixiZ module, which is also the first heatsink for the diode, the heatsink around AixiZ is the second one....
Otherwise, my v3 Heatsink/Module IS the module, it can't accept an AixiZ, you'd have to go with my v2 HS/M, which accepts AixiZ nicelly..
However i usually select the heatsink that fits the AixiZ SNUGLY, for optimal thermal transfer.
The only thing we can do is for you to send me the PHR module, so i can remove it, put it in a v3, or at least find a v2 that fits your AixiZ snugly.
In both cases i would remove the diode just to put some thermal paste, before reinserting it correctly with a diode press tool.
So how about you just send that module to me, so i see what i can do? :yh:
I have a rkcstr driver and 2 new rayfoss constant current buck/boost drivers coming in.
They are the same size as the rkcstr driver.
That's too bad...
My lasers only have room for a shortened AixiZ module inside... The AixiZ has to be shortened, or the module would not fit in the head...
Does the rkcstr driver fit in your grey host? (the v3)
If not, does it fit in the v2?
What would you recommend ??
The v3 IS the module, that's why i call it a Heatsink/Module! I can't get an AixiZ into it, because it already is a fat aluminum AixiZ module... :yh:
But yes, the v2 WOULD fit your AixiZ module, it was made just for that, however i usually go through large bags of heatsinks and AixiZ modules to find press-fit modules for the heatsinks, and then use those, because the thermal transfer will be better if i use a module that fits SNUGLY.
As for Rkcstr driver... It's a very fine - stable in current driver, but can't run off ONE Li-Ion for any diode at all! It needs two Li-Ions for reds and three for blurays...
I once butchered Rkcstr's driver to make it 12mm long and get it inside this host!
Then i had to power it with TWO Li-Ions, to power a RED diode..
This required me to use 1/2AA size Li-Ions, with low capacity - half the length of an AA, same diameter.
The end result was that the tiny laser got three times as hot as it would with a cheap boost driver, like the FlexDrive...
The power was VERY unstable, not because of the driver, but because of the HEAT produced by the driver...
A BluRay diode would require THREE Li-Ions, and my host is made to accept one AA size battery! They probably make 1/3d AA Li-Ions, but the laser would be cooked by the driver from the inside.
It's impossible to do with what you are proposing. You'll just have to trust me and go with the right parts i'm afraid...
I'd love to get a PHR in one of your hosts. Preferably using the PHR maybe even driver I got.
Better than the PHR I got taped/rubber-banded to a 2-cell lipo battery with bare wires... :crackup:
Well, send me the parts, and the Rayfoss driver, and i'll see if there is ANYTHING i can do to make it fit with the original driver.. If not i'll still buy the Rayfoss driver off of you for testing, or return it to you and use a FlexDrive.
Did you manage to pay for it with PayPal?
Well, your laser lacks a heatsink, which is not too good for the power nor the diode... They last longer when cooled...
I could always make you a box-laser with three Li-Ions and the Rkcstr
driver, separated from the diode with distance, so as not to cook it and of course a big heatsink on it?
Like an altoids box, which i'm making for another member here. :yh:
(see the pic for the PHR rubber banded to the battery hahaha)
(and yes the heat shrink tubing over the wire solder joint is still un-heatshrinked lolz)
I saw it... What's the laser on the right? What host is that?
PS: I shouldn't really be buying anything considering I'm broke.
But if it helps ya make some $ for the 8x murder I'm in for it.
Hey, you and me both, brother...
I am, or rather will be broke in a day or two, when i order two more 8x's for the MURDER pool... :evil:
Anyway, i'll do my best to prepare you an affordable kit for your laser build, but i'd really like to see the parts for myself, so it would be done right, ok?
There is no reason the laser should not be as good as it possibly can! :yh:
I have a feeling that my Key Chain CR2 kit may become a candidate for your awesome work!
