The original switch still works even though i got a replacement.
Another thing is that i desoldered a spring by mistake and now i cant solder it back...
Fffff, i may sell it in the near future so it must look good! :beer:

Thanks again,
Jim

First of all, thank you both for your help!
I tried following that tut a week ago and somehow i sorted my batts... :(
I have fixed it now, but the thing is that it looks pretty bad....
Anybody wanting to trade a battery holder with something else? :thinking:

Jim
Mine came out great! small cut lines, good solder joints, I even turned the spring around. Pretty straight forward. I suggested in my post to take it slow/use a marker:tinfoil:

Your very welcome I wish it would have gone smoother like butter.:)

Try the solder blob method on the spring use flux!

I don't think anybody has a spare holder. The host come with one battery holder and it is an essential part of the host. Maybe ask Ric for a spare one ?

Thanks for the link! :beer:
BTW, right now i have cut all the traces from my holder so each pad is alone. :p
When i get home in an hour or so, i will try once more with the new switch,
lets hope it will turn out well! :)

There are 9mm diodes that can go higher than this laser. You need to push it harder. :)
Like the 3.5W single diode laser of DJNY.

What driver did you use? I have 2 9mm diodes on the way and have yet to find the right drivers

Thanks
I think I have used the 2.1A X-Driver. The 3x 18650 batteries in series is a good match for this driver.

It was a good 9mm diode. I should have driven it at 2.5A and probably got an output close to 3.5Watt. But back then my LPM goes only to 2Watt max.

It's still in good hands ;) and still lazing strong :)

Nice job, may i have the complet list of items particularly for driver, host battery ....:drool:

Thank you
***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:
