    NUBM07E 465nm 2.9W Diode Test (Hitting 470nm+)

    I'm currently running M462's at 1.8amps continuously in my show projectors which is their stock current with X-Drives. With Z-bolt sinks and a little bit of airflow they literally run for hours with no issues. I still have a couple 445's I want to get rid of and the NUBM07E looks like a solid...

    2W laser to remove wasp's nest

    A bit more environmentally friendly using a laser. I'm also assuming these are small golf ball sized nests. Not the football sized white faced hornet colony that will put you in an emergency room if you tick them off. Ditto on only doing this if it's a necessity. I know some people are very...

    NUBM07E 465nm 2.9W Diode Test (Hitting 470nm+)

    I still have some 445's left over in my concert projectors I need to swap out, and can't wait for these to hit the shops. One of my 462's runs closer to 465, and the color is glorious....can't wait to see these in action. My older 445's are really starting to look lame by comparison. At 465...

    Movies with actual lasers in them

    Still looking for the earliest film with an actual laser in it. 'Demon Seed' so far is the earliest I've found (1977). One of the characters in it actually defeats a robot blasting an argon at him with a handheld mirror, which is pretty smart if you ask me.

    Eli5: why are blue lasers so cheap

    638's have already dropped in price a lot. Consider what they cost at the 1watt level 5 years ago. It's just the demand for 445's is much higher, and production has caught up with demand. 638's will keep dropping price as large format video applications drive the market. Same with green DPSS...

    "The Blues" - 449, 460, 478, 495

    The blue cutoff with digital CCD sensors is typically 450-455 (dominant) so digital cameras of any sort really have a hard time rendering the color of lasers below 462nm as anything other than purple. Difference between 445, 462, and a mutant 462 I have that's running closer to 470nm is pretty...

    ATHENA laser weapon

    Until an engineer loads a few JiffyPop tins in one of the test targets I refuse to take these tests seriously :-) If you don't get the reference - shame on you.

    Waterproof Laser Module For Burning Pest Anemones In My Fish Tank

    A conventional high powered 445 doesn't need to be waterproof. I can easily blast Aiptasia in decent sized tanks from outside by simply focusing my 2watt 445 to the proper range. Doesn't work anyways. You can incinerate the heads, but the pests simply retract in the rocks and grow back. My...

    Green Lasers - Inherently Unreliable???

    I've tried for years to get a decent, budget greenie to mount in my DJ projectors to compliment my reds and blues. Just something in the couple hundred mW range and mounted in a decent heatsink. Tried several of the vendors listed here...no dice...get maybea dozen or so hours out of them and...

    Klingon D7 Battlecruiser "Klothos" with three lasers & running lights (pic heavy)

    Re: Klingon D7 Battlecruiser "Klothos" with three lasers & running lights (pic heavy) Nice work! Bit of trivia, but in Star Trek - The Motion Picture the photon torpedoes shot by the K'T'inga class cruisers at V'ger in the opneiong sequence were created by shining a red laser through a crystal...

    Possible lowering of exotic diode prices?

    Refreshing to note that we have practical minded people here who understand a huge chunk of our hobby is simply driven by the display / television market, and it is what it is. RGBY for display offers significant gamut improvements over RGB. The problem is that LED or regular solid state light...

    heatsinks?

    Many of my projectors use the same kind of heat sink with those mini fans on the back. They seem to work ok up to about half a watt. Then again I had a 500mw Mitsi 638 die after about 50 hours in one of the gold colored heat sinks you see from the same vendors because it didn't have snug enough...

    heatsinks?

    I can't stand cylinder / screw style heat sinks because variations in machining inhibit proper thermal transfer. Visualize a cylinder sitting inside a smaller cylinder and how much contact is being made. If it's machined tight it will be OK. If it's not machined within tight tolerances you will...

    High power needed - why?

    I'm one of the few here where lasers are part of my business and I use them for my nightclubs, glo-bowl, etc. I'm also a hobbiest and a couple of 2w pointers, but for the most part I use them in front of crowds. In this respect more power is better....to a point. I used to have 200mw reds...

    FroliCat BOLT Laser Cat Dog Toy

    We have a few running at the animal shelters I volunteer at. They'll keep the cats entertained for a bit, but the repetitive patterns soon cause them to lose interest. Also noisy.

    M462 in Reke projector / I likey a lot

    Dead middle. It's about a 7-8nm deviation on both ends. Like I said, I can read blue LED bins almost dead on. If I get my spectro calibrated I'll test to verify, but trust me, my eyes are pretty good. The one is really close to 470. It's what we call 'Windex' in the DIY world. Yup. Can I get...

    M462 in Reke projector / I likey a lot

    As an interesting note, the second 462 I ordered from you is a rather obvious color difference from the first. First diode is actually closer to 470. Second one dead on 462. No need to pull my spectrometer since I'm used to judging blue LEDs with my eyes and am pretty close. The 470'ish diode...

    Self-Defense ~ Bear with me for a moment!

    Actually, the current incarnation of a 'phaser' might be the Active Denial System or 'ADS' the military was working on. Just focus 100k watts of 1mm wave energy at an area and watch people scatter. It's an interesting read if you look it up on Wiki, and a bit scary because it's already been...

    Self-Defense ~ Bear with me for a moment!

    This. I can tell you from first hand experience retrofitting projectors that a defocused 2watt 445 at a distance of 30feet is more than enough to cause you to turn away instantly and rub your eyes in pain. My 10watt Luxeon M's LEDs in polished reflectors are a bit worse. I also recall vividly...
