So nice that even commercial products like super cheap laser engravers use CD trays to mount their lasers on.

That’s a good Laser 101 page, thanks for the link. Another comment regarding MDF: try to find MDF that is formaldehyde free (cuts cleaner or gives more precise edges) and always check your thickness on each piece. 1/4″ MDF from Home Depot can range from 0.220″ to 0.265″ in my experience.

Samsung is expecting operating profits of 6.5 trillion won for the second quarter, a drop of 56% from 14.87 trillion won a year ago caused by the downturn in its memory semiconductor …

The fact that polycarbonate absorbs IR radiation is a good thing; it means more of the beam energy goes into cutting the material instead of being reflected around the machinery. It will cut pretty well even without kilowatt level power, but the trick is to use a coaxial nitrogen assist jet to prevent the blackened edges. The nitrogen jet is also good for preventing the “gooey melting” issues that you get with some of the other uncuttable materials, and will blow out flames on cardboard and some of the other items.

It was a moment of shock, not pain, for Aiden, who had seen something fly from his peripheral vision, but assumed it was a piece of wood.

“When he came back out and shot his first practice round, I think he shot a 23 (out of 25) in his first round back (in skeet) and I was like, ‘Wow, it doesn’t seem to have any effect,’” Mark said. “His ability to stay loose, as I talked to him before he came back to the team, he seemed upbeat, he seemed mentally in the right frame of mind and it seemed like it’d be good for him because he was dealing well with this. That just transferred right over to his shooting right once he came back.”
