This is what the laser with the lens looks like finished. I'm currently loading it and will record videos soon

In the evening I put the BMS on the battery and assembled the laser. Everything worked normally. I also put the lenses on and they fit perfectly in the center of the beam. I played around a lot and the battery fell out. It turned out that the BMS was somehow defective and could not charge the...

Can you take pictures of the damage and your project in general? In general, it is good to have information about these infrared lasers, how and what is done. I received all the parts for my 260W. It will be ready soon. After it, I will start assembling the 500W. However, I will do it in a...

The 260W one is not ready yet. I'm waiting for a few more small parts for it. When it's ready, I'll let you know how it handles the cooling. The 120W one heats up fast and the temperature drops very slowly because the fan is weak. I can put a powerful one, but it will have to stick out because...

Today he made a small adapter for this lens. Now it fits tightly into the other adapter. The focus can be adjusted. I removed his first expansion lens, because I glued the one from the other lens and I don't want to remove it. The two outer lenses are his. They are glued. It works quite well...

I have several blue lasers over 7W with a P4000 driver, which works with two batteries, however. There is no problem with them. And I modify these myself by changing resistors. They have a smooth start. The bad thing is that you have to put them between the radiator.

I found them on another site. There are 17mm and 22mm. I guess they are the same https://convoylight.com/products/detail/15207616 https://convoylight.com/products/17mm-6v-5a-boost-driver

Can you provide a link to the driver you are using?

Today I made a focus adapter. I will be able to use it with other lasers. It turned out very well and is very stable. Really good focus at 40-50 centimeters. With adjustment it can burn things at 3-4 meters. It's not much, but I managed to create this from the lenses I have on hand. I have many...

Today I connected the 120W laser. I didn't have a Secret key and I made a bridge on the plus in order to be able to disconnect the connection so that it doesn't turn on unintentionally when I'm not using it. I'll have to put a metal plate in the front part, because when trying with lenses it...

The cooling will be active of course. There is no danger of overheating for me, because I always put a temperature sensor with a display and see how many degrees. In this case, I always use the lasers for short cycles. 10-20 seconds there is no danger of overheating.

These are the same but have an amperage adjustment option https://a.aliexpress.com/_EGEFm0c

Yes, I know. I can adjust it to this high amperage using the copper wire, like in the video above. But I will use the 1800W boost driver. It is up to 22-23 amps. The power supply will be from two packs of 6 26650/5000mha batteries connected in parallel. Because the BMS I have outputs 40A. With...
