I think Google offers a service that'll translate webpages but it only really captures what's written in html. I've just been using the Google translate app on my phone and pointing it at my screen. Crude but easier than learning Mandarin ;)

Can you guys search in taobao without having an account there?

I could do it couple of years ago but since last year it asks me to log in every time (in Chinese of course).

If you use google to search their site you can e.g. "site:taobao.com nubm31". Some of the links returned are intended for the app, you just need to change "item-amp" to "item".

Yes but before I could search in taobao like I do in Aliexpress: just "nubm" and it gave me all nubm05, nubm06 etc.

You's guy's are CRAZY !!!! MMMMHAHAHAhahahahaha........ I think this array could be a candidate for an " Autonomous and Adaptive IR directed Motorized Focusing augmentation" Just think about it !!!! I am sure the Boyz @ dArpa have....MMMM...???.Target acquisition locked with IR distance method....Auto focus engagement.... Laser ON ......PoooooF !!! " Just like shooting Ducks in a Barrel " Styro/LSG...MMMM...I Double Dog Dare'ya !!!.....MMMmmm?? " I assure you, such power exists " CDBeam

NO REPLY ????? Blinded by Science ???? In awe at the Magnitude of the " Mad Scientist Syndrome " ????? I though so !!!!
MMMMmmmm ????? What the hell is a gigawatt?

Hello,



I have purchased other stuff from them before, its my goto for quality optics and drivers.
Other company may be swisslas.ch , they also don't have all the components on the site, but i don't know if they have something.



Thats NICE! hope you don't kill your module, i am very scared to do so.


Yes you can, its a classic laser driver with 0-5v modulation input. For now i connected a powersupply to control the output power, eventually this will be changed to the original laser cutter power control.

As i understand is it possible to input 3 different modulation signals for RGB, as its normal used for RGB laser projectors.
But you can connect all 3x2 channels together to get 3x 5A current for your laser diodes with up to 48V for the diodes.

Each row of 5 are around 22V, so 2 rows are connected in series for 44V which the driver can handle.
So only 2/3 of the driver are really needed for the lasermodule.
2x 10 diodes in series (2x 2 rows in series connected to 2 outputs of the driver).
I have used 2 rows in series and connected the remaining rows to the 2 remaining driver channels, this gives me the possibility to control the current independently, i don't really need it but its nice to have.

The modulation input seems fast wich should be good for graphic cutting e.g. raster and different intensity engraving.
The curves at the data sheet indicate that there is no overshoot in current if you turn the current up, so the diodes should hold up to overdriving them.

This thing also has dcdc conversion integrated, this means it doesn't "burn" the voltage that's not needed (like styropyros driver) so it has a much higher efficiency. This is what sold me to the driver, it doesn't need much cooling, also the protection features are very good.
Would you be willing to upload a video or pictures in explanation of what you said? Lol I followed what you were saying but I was wondering if you could show a visual representation as well? Please

Hello,

i think this does take significant amounts of time. Time is short and I don’t have any at the moment. I am hoping to get some pictures postet form my array. But
I will not make Movie.
Also I don’t understand what I would need to show?
If you have a question/ something you didnt understand I can try to explain it. However English is not my first language, so I sometimes have a hard time explaining stuff.

If you need more informations about the driver I would Bett that the company would help you. They also have a new website that has some explains about drivers.

But it seems like the project I was trying to do is dead to me, I can’t get the array focused down to a acceptable beam diameter and this will ruin cutting quality.

Hi Farbe2,

Yes let's leave movies fo YT actors like styropiro. For a researcher a row of pictures (slides) is as informative as movie. If the picures show numbers.

Could you please post pictures of the spot from your NUBM31 array on the piece of millimeter paper (or just paper with centimeter marks) on the wall 5m away?
This is to compare the divergence with my Osram chip and NUBM08 arrays. I did such pictures at 0.5A current with my phone camera through OD6 googles in posts 15 and 20 of this thread:

Of course no need to do it if you have little time.
But if we want to know more about these new lasers it would be good that all of us share our results.
