    Carbon Fiber Wrap Hosts

    Looks amazing. One day when I decide to get a NUBM44 something like this would be ideal

    how to clean laser diode??

    The diode window can not be cleaned, whatever dust gets on there will get burned on permanently. For external optics, you can use some compressed air/keyboard cleaner and a lens cloth with a bit of alcohol.

    First completed build! And a learning experience

    Agreed, the greens that anybody could build on their own far outclass any of the various common green lasers on the market not only in terms of the diodes you can use but also, like you said, the importance of a copper/aluminum heat sink with preferably as much mass as possible for the given...

    First completed build! And a learning experience

    Battery extension tube from SL installed... High quality Samsung cells selected and charged... The spot size at 75 ft in broad daylight... This thing is truly magic!!

    Quick writeup on two Chinese lasers: WORD GX "Amazon" 445 nm vs. Thor H 3W 445nm

    My main concern is that it might be a very old and used up diode taken from a projector or something and not a clean pin for this specific unit. I'd guess that happens quite a bit with these cheaper lasers.

    Quick writeup on two Chinese lasers: WORD GX "Amazon" 445 nm vs. Thor H 3W 445nm

    Sorry to hear about your M2. I've only had one of these units but it may be that the 3W Thor H has a higher level of care and QC put into the manufacturing? It looks like they're sold out of them on laserpointerstore as well, I might've gotten one of the last ones. It sucks that this appears to...

    Quick writeup on two Chinese lasers: WORD GX "Amazon" 445 nm vs. Thor H 3W 445nm

    Heres a short follow up, the Thor H is still holding up great. The main issue I had with this unit is that the focus is just slightly offset from infinity when screwed all the way in, making it difficult to turn it the single tiny hairthreads distance out to get a true "infinity" focus. Also, I...

    Where to buy?

    With the world events the way they are right now (shipping from other countries), probably the only way is to assemble it yourself. However nobody here knows anything about you and you haven't made an intro thread so we can't in good conscience recommend you parts.. Do you have safety goggles...

    NUBM31T 95W 455nm

    So is this really going to impact the availability of single blue laser diodes (ie is Nichia actually going to discontinue their other diodes and will start only producing these in block arrays like this)?

    Styro's video on this unit is up: 🥶😮🤤

    Project for beginner

    I've gotta check out Liionwholesale too. Right now I've got some Nitecore 18350s along with an i4 charger and they're excellent. Ultrafires aren't THAT bad, but you won't get much juice out of them compared to the better options. My Ultrafires have never exploded or caught on fire, lol

    Hello. I have some questions about Laser Pointers.

    No, the concept of your friend's idea. Laser output is not measured in "brightness," it's measured in mW or W. If he wants to describe the "brightness" of the laser then he needs to wax poetic and be a salesman, not try to invent a new unit of measurement that only he uses when he most likely...

    Hello. I have some questions about Laser Pointers.

    What on Earth did I just read ? o_O

    Yup, I’ll post a comparison pic up after I install it when I get home from work Edit: Here we go, here's a pic of the newly installed sink, next to the old one for comparison: It's just slightly more substantial :)
