    New laser drivers designed by me.

    +1 on this. I would LOOOOOVE some 16.80 mm or 17 mm circular drivers, be it buck, boost or linear. Personally, i need this form factor to complete a set of three stainless steel C3 builds with R G and B. This form factor of drivers would also allow for much shorter and compact builds.

    NDG7475 Crushed

    There are a few threads here on setting driver current. I use two torchlight LEDs in series to act as a 5V load. Just measure the current using a multimeter in series with the test load. Then turn the pot until the current reaches your desired level. For storing extra lenses, I just throw them...

    NDG7475 Crushed

    Maybe the output just looks like trash...because the diode window has been crushed and the light is bouncing around in there with all the small pieces of broken glass around? Anyway, to decan a diode you would also need to remove the diode from your module. Not sure if DTR sells diode removing...

    Best driver for Sharp 488nm GH04850B2G

    I have a few of these drivers, handy little boost drivers but for whatever reason it seems like its doesn't like the higher Vf diodes. Used it to run a sharp 505nm 30mW and couldn't get it bright enough to my liking, maybe we just gotta mod the shunt resistor and allow for more current output...

    G8 Solutions

    Uhmmm basically his module is just a longer version of the standard module, to facilitate the longer focal length of the G8 lens. You don't need to do much, just press your diode into his module and it will work with a G8 lens. No need to move your diode position around or anything. As I said...

    G8 Solutions

    The G8 lens is basically the longest focal length lens we normally use for our lasers. This means it has to sit quite far away from the emitting point of the laser diode, to get a good infinite focus. The length of the G8 lens holder isn't a problem. Even if it was longer, it will still need...

    Building a "everycolor" / RGB >3W Laserpointer

    Not much to say here other than: "Damn..." I bet everyone's watching closely to see your progress on this build. Side note: It seems like i have found the reason why my sharp GH0637AA2G died. I was driving it around 600mA with an amc7135 driver, it was a really basic driver with no...

    Videos you wish to share part two.

    Not strictly laser related but this video goes into detail on colours and human vision. Kinda makes sense why 488nm lasers are hard to capture on cameras since the camera sensor is RGB and not continuum. Heck, even our eyes are RGB. PS: If you are interested in special effects and CGI...

    New Sanwu 304 green laser not working (solved)

    Ah, then it's probably other issues/a dead laser. Since you already contacted sanwu, that wouldn't be a problem. Sorry to hear that your laser is DOA but those 303,304 style lasers aren't exactly high quality. But it's a good thing that you purchased it through a reputable source such as sanwu.

    New Sanwu 304 green laser not working (solved)

    Try using the tail cap from one of the other 304 lasers. It could be a tailcap issue. I had similar problems with a 303 green laser. If it is a tailcap issue then you could just ask sanwu to send you a replacement tailcap.

    I think I got scammed

    Those pen lasers are hard to get in higher powers. Most of them are around 5-50mW at best. Also, if the brightness decreases suddenly, it could mean that the laser is mode hopping/ the infrared pump diode is broken. Anyway, those pens lasers are literally the cheapest commercially made laser...

    Need Help Building Green Laser

    Hmm I'm not too sure about that. I think they do offer protected cells. I monitor my batteries constantly to make sure they don't discharge to 2.5V But yes, I'd say that a protected cell would be better in this case.

    Need Help Building Green Laser

    Alternatively you can use two 18350 cells in a c6 type host. I personally use two Efest 18350 (each supports continuous 10A draw) and they work wonderfully. Edit: Make sure you use a buck driver when you use two cells and a boost driver if you use one cell.

    Is this laser any good?

    Yikes. First time i have seen this in the laser community. I know the prices of some earphones/headphones can shoot up in the same day when some youtuber drops a review on them. All the more reason to go DIY.

    Is this laser any good?

    Websites such as Sanwu and Jetlasers are well known. Countless members here have purchased from them and are happy customers. I have read about their customer service and the only boo-boo i've seen is regarding shipping, which is not really their fault. Wicked lasers used to be a legit site a...

    Faulty Laser Diode? Or did I fry it...

    Those Sony 405nm are kinda wack imo. I had a 150mW version a while ago. I decided to over drive it slightly, I'm guessing 200mA. It died after 3 days. I think it's just the nature of these 405nm diodes. I heard that they are very delicate to current spikes and seem to die often. My friend has a...

    Where can I buy a 7 watt laser?

    I think the biggest sin/crime is him choosing blue lasers for a death star build when it should have been a green laser. :confused:

    Where can I buy a 7 watt laser?

    If this post is real... I mean.... How do you keep going after they confiscate your items? I'd stop trying after the first attempt. At this point I'm kinda used to seeing these fishy posts but seriously, it just feels like we are being sent running in circles answering these posts. It doesn't...

    Newly Completed 1W Greenie

    I got the G7 from taobao and G8 from Trinh. I'm not too sure about other sources, but i think some place like Dtr's laser shop, survival lasers or eBay can be good options if you live in the NA.

    Newly Completed 1W Greenie

    If you have some isopropyl alcohol and a piece of microfiber cloth, you could use it to clean the lens. Just take everything apart and give it a gentle wipe, and then put everything back together. Do try to use 99% isopropyl alcohol if possible, lower concentrations of IPA will leave water...
