***EDIT*** Smeerworst has tested the laser with his Ophir LPM and the laser hits the 3 Watt mark !!!
Here is another videolink. ***EDIT***

First I want to thank Eudamonium for making the heatsink and the focus adapter. They are really beautiful made. :thanks:
And to DTR for providing me the 9mm diode. :beer:

This is my first BIG build. I was at cnqualitygoods.com for the blue silicon tailcaps when I saw this wonderful host. This host has room for triple 18650 batteries. I bought the host and ask Eud for making the custom sink and focus adapter. When the parts are arrived I started the build.

The original host.








Reflector replace by the enormous sink.




Custom made focus adapter.


The whole host is basically a sink. Reminds me of the Sandworm in Dune. :crackup:


GITD tailcap.






Battery holder for 3X 18650 in parallel.


The middle piece can also be unscrewed. I didn't know that till later :)


The workmanship is perfect !


Next to the tiny C6 sink.


I polish the copper module for the extra shine :)


9mm 445nm diode press in the module.


I use the original lens from the 9mm diode. The lens barrel was sanded to get the lens closer to the diode.







The driver version 1

I used dual Ben Boost for the build. The main ic is heatsinked with copper plate.




The battery side of the pill.


Triple Sanyo 18650 in the holder.


2.26A :eg:


The horror
I couldn't get the dual Ben Boost driver stable. After 8-15 sec the power drop dramatically. Somehow the drivers can't maintain the high current.

I can't figured it out what is wrong. Maybe the silicone wires are too thin or the inductors are too close. I don't know. :undecided:
I decided to ditch the drivers and rebuild the power suply from scratch.


The driver version 2

This is a buck driver. I have been using this driver in many build. The main ic is heatsinked with a piece of aluminium. This piece it touching the pill from above.


The battery holder has been rebuild to fit 3x 18650 in SERIES.
I had to figured out which line to cut and and connect the other points.




The driver fits easily in the large pill. A piece of aluminium is connecting the driver and the pill for heat transfer. I put some glue on the edge to strengthen the construction.


Pushing the boundaries of the 9mm diodes. The driver gives 2.222A
The laser gives 2.8+ Watt !!! :drool:
I have to reduce the beam with a blue filter and two UV filter. The multiple filters block 29% of the beam so that only 71% hits the LPM !
That number must be multiplied by 1.41 for the actual power. :eg:


The LPM reading must be multiplied by 1.41 !

BEAMSHOTS :

I have only a few beamshots. My ballhead on the tripod was broken so I couldn't use it for steady shots. I will add more pictures when it is repaired :)



If you made so far, kudos :D
Thanks for watching !!! :wave: :thanks:

awesome build! :D Weird about the benboosts though.. Sure it was not a heatsinking problem?

Anyhow what an awesome build! i am just craving for a big boy like that.. < Checking what i could sell to up my paypal >

Good luck with that bad boy :beer:

greetings,,

EDIT: must pread rep :(

Very nice work. I have one of these hosts but I still have not had time to built it yet. I am thinking the higher forward voltage of the 9mm may have been giving the boost drivers a hard time. Anyway the buck is certainly seem to have worked out very well for you so congrats.:beer:

Re: 2.8 Watt BIG BOY single diode blue laser 3X18650 !!! ULTRA HEAVY PICTURES !!!

awesome build! I love it.

I have to get my hands on of those hosts too! :D

I have one question though. That driver is using AX2002 which is a 2A max output buck regulator. How did you get a 2.222A out of it o_O

What resistor did you use? 0.11ohm?
Maybe DX updated the IC to the AX2003 which can handle 3A of output current. :bowdown:

Do you have another one you can test with say 0.1ohm resistor or 0.09ohm?

WOW, that's an awesome laser. I'm sure a 3W of 445 will certainly amaze everyone :gj:

Thanks for the kind words. :beer:

I can't read the ic. The top is sanded. I replaced the set resistor with R120 and 1R00 stacked up. I have use this buck driver on 1.8A without problems in many builds so 2.1/2.2A isn't far away.
It is like setting the LM317 to the max. If decent heatsinked the LM317 will go higher than 1.25A

Nice build man! I like it so much!
I'm pretty sure your laser is much more than 2.8Watts, may you have a >3Watt laser there :evil:

Send it on someone with Ophir LPM.
