Hi guys, it's been a while I have been away from this forum :) But I was using one of my m140 diodes in dtr's copper hosts when it started being weird. So I opened it up to see that my positive pin on one side had snapped and the wire went with it. There was is a little bit of the pin left...

I haven't posted here in a while! But I've been lurking, I have been using the LM317T circuit to drive my diodes. But from what I've seen and from what others have said it isn't very efficient. I don't care too much about it and could just go buy a prebuilt driver, but I was just curious if...

Hi everyone, usually I don't like buying anything from China due to long shipping time to the United States, inconsistency and loads of other factors. But I've been seeing a lot of laser diodes being sold from China. Does anybody know if these are reliable or are they just clones/poor quality...

Anyone have an opinion on soldering this wire to a laser diode? https://www.sparkfun.com/products/11367 I've been testing how flexible it is and I saw something from DTR stating he uses a pretty flexible 26 gauge wire, although this is 22 Gauge anybody have experience with it? Thank you

Holy hell, so I just got this M140 like someone on the forum here suggested from my previous post(Thank you). And It is really really small, Any idea on how to keep this cool? Any enclosures anyone would recommend?

Kind of new to this forum as well as working with lasers, I am very exact about my safety with glasses, and being careful not to burn myself but this is a 1W 445nm and I have some ideas but I purchased it as a "kardel gattling laser" and I've removed the shafts on the side that look like...
