I got my 2.8W $100 laser working pretty good now, here’s the video link.

Another video.

It is a Nichia NDB7875 with a G2 lens from DTR laser shop. It’s running on a generic Chinese laser driver tuned to 6.5v @ 1.7 amps.

@leo69, I’m using a 25 amp 12v regulated power supply. Thanks for your great guide.
