The one pictured is the NUBM0E with the 3 Element lens. I know the guy with the laser from the photo.

Today I added these strips for wardrobe and cabinet corners. I'm going to put two phone magnets on top of them that I used for the front one, and that's how I'll put the lens on and off. I put a little glue on each one because the screws don't grip very well in the aluminum fins of the radiator

@RedCowboy I don't know why, but it always bothers me when I put optics in front of the array, because the optics without a coating to return the light back, make a reflection and the focus is right in the array itself. I did a test the other day with a biconvex lens that I placed in front of...

Yes, I got that. I also ordered a double concave lens and a convex one. I ordered from several places different lenses. When they come I will experiment. I'll actually be able to do something similar with your adjustable lens laser that's in the box. Simply, the box will be placed on a...

@RedCowboy I found on Aliexpress a double lens with a focal length of 1250mm. I will write when I get it. Its price is very good right now. 21 22 46 52 mm double cemented Achromatic Convex Objective Lens DIY Professional Refractor Astronomy Telescope Accessories...

@RedCowboy Thanks. 👍 I need a single lens because I want it to be compact and easy to carry. I have ordered several lenses from Aliexpress. I might try to assemble a lens. 30mm 40mm 50mm Glass Double Convex Concave Glass Lens Focal Length 50mm 75mm 100mm 150 mm 300mm Optics DIY Projector...

I am wondering if there is a single lens that has a long focal length of 1 meter or more?

I assembled the laser today. He had a lot of nerves. I spent an hour trying to remove the array from the board because it is very likely that if force is used it will be damaged. Then I assembled everything, having previously set the driver, which was brand new, to 4A current. I just put...

Thanks for the reply. I will be testing them very soon

Thanks. Apparently they improved them. Because they used to have problems and damage the diodes. Probably old info. I will use them for NUBM0F. I think they will do well with him...

Hello. I bought 3 of these drivers and am interested to see how they perform. Does anyone have experience with them?

Не знам защо не можеш да го отвориш. Те работят за мен. А моите са от Aliexpress и Ebay https://de.aliexpress.com/item/1005005906526822.html?srcSns=sns_Copy&spreadType=socialShare&bizType=ProductDetail&social_params=21272589986&aff_fcid=22c4d5474edd4d5f86a2ca8ea44fdcd6-1...

Hello. I came across this seller on Aliexpress and noticed that the laser array prices are very good. They may have been used, but I can't tell. If the topic does not follow the rules, please remove it. I have nothing to do with Aliexpress. Just found this amazing item on AliExpress. Check...

I don't use safety glasses. Even with my current 75W+ I just watch where I shine. You will hardly find NUBM0E anymore. His successor is NUBM0F

Everything is ready. I expect to receive the NUBM38 array this week and have everything wired up and set up. We made a plastic one that I glued to the fan and I clamped it to the drill. I took some pictures to see how it would look.

Today I installed a new active cooling with dimensions of 150/69/36mm with 2 fans. At 4A current, I can say that I am very satisfied with the result. It is very important for me that after stopping work, the temperature drops very quickly. With the front radiator, this was impossible.

@RedCowboy Yes, I will share impressions of NUBM37. I expect more power at close range. At 4A it will probably go up to over 150w. I think a 200mm radiator with 3 fans will do for 1 minute of non-stop work. I will put a thermal switch at 70C and an electronic thermometer to see the current...

@RedCowboy Today I bought another laser array, but this time it's NUBM37 / 125W. I also bought 2 of these 900w converters. As I will use one of them to power the NUBM37. But that will be a new topic. For cooling I will use one of these radiators. I will take the size 200mm, and there will...

Today I was able to do these things on the body. I put in the converter, there will be a second one for the fan. The wires to the diode and fan will go through the top of the body. Tomorrow I will do the element for attaching the radiator to the body.
