    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...

    New 520nm 500mw Build

    Just completed a new build, 520nm, 500mw (driver set to 600ma output) buck boost driver off a single 18650. I won the Nichia NUGM01 diode for 35$ shipped on ebay, so I absolutely had to build a new handheld solid state green laser. Used a stainless waterproof Cree 3W flashlight host, also...

    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...
