if it can be pushed harder, 3 watts possibly. its a 9mm diode then you must be using a NDB7875? this would certainly make a good laser for someonewho wants to push it harder
good luck on the sale Grix :beer:
Those batteries are limited by customs to who can ship them out of the country. They are limited inside the country too, but since they don't check packages within the states, it is less likely one would get caught. I wouldn't do it as there are stiff fines for trying to ship hazardous materials by mail anywhere.
I can ship to Brazil, but I can't guarantee that it will pass through customs. But in my experience as a laser seller it rarely gets stopped. Only ever happened with an Australian customer once. But like Paul says it's not a good idea to ship the batteries together, it increases the chance of being stopped in customs.
The laser is practically new. I built it like a month ago as you can see in the video, and haven't used it much after. Less than an hour for sure. I only built it for the video really. EDIT: But the diode is a bit used, it's salvaged from a different build. But these diodes are sturdy.
