I received my two 6W lasers yesterday & need some help with the wiring. It only took 2.5 weeks to get here from China. I still have to wait for the 3.3v-5v shifters & safety glasses before testing it, but in the meanwhile thought I would see if I can get the wiring straight before then. The color coding on the wire they sent would lead me to think their webpage is wrong, but they might not follow standard wiring colors of red for + & black for ground. My wife pointed out something about the Chinese that I had not heard before which might be why somethings are backwards to us. Traditional Chinese text is read in columns Vertically from Right to Left. Here is the Wiki page on that.
Here is a photo of the laser & parts I received showing the red & black wire on opposite side of connection as they show 12v & Ground on their website page.
Here is the page on the 7W laser as I could not find a wiring page for the 6W laser.
Since @dart1280 has used this laser or @dkj4linux might be able to confirm what the wiring is for this.
Also, does the temperature lead get hooked up to anything? Looking at Mike’s circuit diagram from his build page, looks like it is not hooked up.
