    175ma GH04850B2G 488nm Build

    Thank you for the reply. That helps a lot, as I have no LPM to measure output; I was just assuming that 175ma would yield around 100mw. I will modify it up to between 190-210ma and see if I can gain a few notches in visual output. If not, I will titrate back, to ensure temperatures are well...

    WHY so many 'necro posts' lately.

    Been browsing and lurking this forum for around 4 years, and the black theme is so much easier on the eyes, especially late at night. Also, the other forum I post on regularly, [H], has a similar grey colour scheme, and it just feels at home! As for the necro posts... Well, this forum is...

    Why is my 200mw red laser dims

    What is your laser. Did you build it, or did you buy it? Are you sure the driver output is correct? Are your batteries correct? Are you heatsinking correctly? Etc. Etc. We need a whole bunch more info.

    My new build $495nm and 515 nm laser

    The 495nm blue is an absolutely amazing colour. Fantastic. What's the 495nm diode's part number (model # or whatever). Also, where can I get one!

    NDS-7175 Skyblue LD ?

    I honestly can't imagine how bright these diodes would be in the 483<x<490nm wavelength range as per the spec sheet. The beam and spot on a properly focused/collimated 488nm @ 100mw is already very visible at night, let alone an order of magnitude stronger. All these solid state diodes, in...

    175ma GH04850B2G 488nm Build

    So, I really wanted to get into some of the more interesting Blue wavelengths, and I decided that 488nm would be a perfect introduction to the 470nm<x<490nm wavelength range, well, without breaking the bank. I don't have many build pics of the entire laser, as the build was rather...

    589nm vs. 594nm Yellow Wavelength Comparison

    I fell in love with the 589nm wavelength because of the adaptive optics used in todays optical telescopes. I wish we could develop a solid state 589nm chip, but barring that, the only laser i will ever purchase and not build is the 589nm.

    New 520nm 500mw Build

    My "soldering station" is literally a stainless steel tiled outdoor bar, on a balcony, 22 floors above the city streets of Toronto. I would kill for a more pristine workstation. I downsized from a massive metal and wood workshop (forced dust collection etc.) to a city condo and it hurts. I may...

    New 520nm 500mw Build

    Yeah, I haven't modded the diode in any way shape or form, other than pressing it into the heatsink using very nice thermal compound. The divergence isn't great, but I purposefully focused the beam to produce a fatter beam than typical. Properly focused, the dot @ 20ft actually isn't too bad...

    Best Driver to Push 500mw Mitsubishi off single 3.7v Li-Ion Cell.

    Exellent. Looks like the best option for me right now. Flexdrives are very hard to come by.

    Best Driver to Push 500mw Mitsubishi off single 3.7v Li-Ion Cell.

    ^ Thank you for that. I was just going to use a DMM to find the cutoffs for the pot, but the AMC7135 is looking like a better option - I can't find the flex anywhere, and I absolutely need to use a single cell for power - Can't use a buck.

    Best Driver to Push 500mw Mitsubishi off single 3.7v Li-Ion Cell.

    Very interesting. I think I'll take one of the IC's off as well. No other modifications necessary? 700ma would be perfect for my intended application. Cheap driver as well.

    15$ DIY Copper Host Tutorial for 150mw Greenie.

    I have a garage with a bunch of tools. Hardly a shop, but I've been building and modding cars and computers for years, so it's sort of a natural progression. My next purchase is a lathe. I have lots of fantastic design ideas, and a cheap stock supply source. I fully intend to produce some nice...

    15$ DIY Copper Host Tutorial for 150mw Greenie.

    It's a prototype. I'm going to make a bunch for my entire collection, with different coloured GITD rings for ID. I'm going to make another to use for my 500mw 638nm build that I posted about begging for help in the red section. And I may put my 1w blue in it... It's a dinodirect diode that's...

    15$ DIY Copper Host Tutorial for 150mw Greenie.

    Hello everyone, I'm working on a very simple, very cheap host to accept either an Aixiz module case or green assembly. As I'm a new member here, I figured I'd post the entire thing as a quick tutorial, as it truly cost me around 10$ in hardware store copper, a few dollars in tools and around 2...

    Best Driver to Push 500mw Mitsubishi off single 3.7v Li-Ion Cell.

    Yeah, that's what I was thinking of doing. Setting up a cheap dummy load and testing it that way. I actually am looking for lower output, since i"ll likely be using a 10440 3.7v. I'd like to get a full hour run time out of the ~500mah battery. And I know, 110$ diodes are downright pricey...

    Best Driver to Push 500mw Mitsubishi off single 3.7v Li-Ion Cell.

    So, I've done a lot of resarch about this, and I'm wondering if anyone has any first-hand recomendations. I'm putting together a mini 638nm pointer, hoping to get around 500mw from it (nothing too crazy, for battery charge lifetime) but I'll be powering it with a single 3.7v protected li-ion...
