    A fresh look for my 589 nm Laser

    I think you absolutely nailed the cool science tool aesthetic. This is certainly one of a kind. It looks like a prop for an indie hard sci-fi film

    450nm osram white pen build

    Looks great! It reminds me of maybe 15 years ago when you'd find those laser pens on ebay/amazon that claimed to be blue but were just cheap 405's But this is the real deal🍻

    Quit my job!

    Sorry to hear that... this thread reads like a bad dream. Best of luck. Hopefully you're able to keep the job and do without his interference

    Laser to scare crows!

    It looks like you aren't the first one with this idea of using lasers to repel birds:LOL::

    Laser to scare crows!

    Sounds like you need a "Sound Laser". Something to direct focused or collimated sound with low divergence at a narrow-range target:unsure:

    WTB: Maglite Heatsink

    Thanks for the tip🍻; sent him a message

    WTB: Maglite Heatsink

    Hey guys, I am looking to buy a custom heatsink that would fit inside the head of a 2D cell Maglite. Either one made to fit a 9mm diode via press, or one with a 12mm bore for a module to be set with a hex screw. Either would work nicely. If you have one or know of someone selling some - I'm...

    Hit in eye with 1000mw 445nm blue laser

    Welcome to the world of lasers. And props for good discretion 🍻 Maybe when they're a little older and understand the dangers you guys can get more involved. Building a laser would make for a great project with them.

    First build, assembled, not turning on

    Glad to hear things worked out in the end 🍺

    Sharp 395nm GH0393AA2G

    No worries; that is why I asked;) Don't let the weasel bother ya either. It's a darn shame something like him happened to LPF.

    Sharp 395nm GH0393AA2G

    I was never much of a fan of violet lasers myself. Where'd you buy these from? (if you don't mind disclosing your source)

    I think Giannis is right here. It's hard to say what killed the diode, but I would try to figure that out before replacing it. Especially if it was the driver that failed.

    Like you said, the diode itself doesn't require much voltage but sometimes 1 battery is insufficient for both the voltage drops of the diode and driver.

    Well you can try 2 rcr123a (16340) batteries and see what happens. These diodes are pretty tough

    One should be able to see a beam at 500mW+ of 638nm no problem. Sounds like there's still an issue.

    that looks plenty bright to me! This is a multimode diode so the beam profile will be ugly to say the least... You can play around with the focus but the the beam will always be rectangular like that Edit: It's a bit hard to tell on the brightness on a second glance. Do you have a LPM? Or...

    First build, assembled, not turning on

    If you can see light but it's way too dim, then I can think of two possibilities: 1) you already killed the diode 2) you're running the diode just below the threshold current (the diode can't draw enough current to properly lase)

    You may have soldered to the wrong diode pin. It looks like the right pin is positive, the middle negative and the left is the case pin. Edit: My next guess is you may have mixed up the polarity somewhere along the way. Do you have a multimeter? This will help troubleshoot polarity problems...
