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

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!

Sadly, i can't spend more cash on this laser....
Is there any possibility you wanna trade? :thinking:

Jim

 

[Blord]

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 ?

 

[jimdt7]

I thought about that, but since i dont have funds in my pp,
the only way is to trade.....

Trade no way (I have faith that you'll get it right) You won't have to spend any money... keep trying you can do this. DO NOT give up, man up, get' er dun.

here is the battery tray for your host.

 

[jimdt7]

Thanks for the link! :beer:
BTW, right now i have cut all the traces from my holder so each pad is alone.
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!

amazing build, you should try to break the world record for worlds most powerfull handheld laser, i bet you could do it.

I´m not sure. ARG is hard to beat :beer:

 

[Blord]

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.

 

[JollyKillBill]

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

Thanks

 

[gecko991]

Beautiful work there, nice and clean.

 

[Blord]

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

 

[frscobal]

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
Thanks for watching !!! :wave: :thanks:
