Hey, so I will not be able to continue building lasers for a while, so in an effort to clean out my inventory, I will be building lasers from what parts I have and listing them here. I will add them as I make them, so be sure to subscribe! I also have a few lasers I will not be needing, so they...

Would the high current draw of the SXD-V3 outputting 4 amps be a problem for 2 red efest imr 18350's in series? Or should I play it safe and go with two Panasonic 18650's? I appreciate any input, and thank you in advance :)

Hello, I just spent nearly all my spare cash and I really want a high-powered green (preferably 532), so I'm selling three of my collection to hopefully fund that. It was tough choosing which ones to sell, but I chose these because they were simple builds, and I tend to be more attached to...

Hello everyone, First review here, I'll try to do Sinner's host justice. So I originally ordered the last Cypreus II with the dual driver mount, but unfortunately that one was damaged in a few spots. Then I talked to Sinner, showed him the damage, and almost immediately he offered to send me...

Hey guys, I want to change my name to simply "Jstr." It's not a huge difference, but it affords me slightly more anonymity, that's basically the only reason.

Hi y'all, so I've been trying to set my driver (Blitzlinear) to 790 mA for a BDR-209 build, but something doesn't add up with my test load. After I attached leads and connected it to a pair of 16340 batteries, I get my 790 mA using the usual 6 diodes in series (dropout should be ~6.8 V at that...

Hi, I have no idea what the problem is with my build, so if anyone has experienced something similar, please help me out. Thank you in advance. Here's what's happening. I am using a rectangular blitzbuck driver and standard 9mm diode. So I connected the driver to the battery tube of my host...

Hello, I originally bought this laser for the diode and driver, but I decided I would rather start from scratch. So, I decided to de-anodize and polish/upgrade it. It turned out rather nicely, and I was battling with myself whether or not to keep it. That was a couple weeks ago. I killed...

Hi, I just replaced the driver in one of my 445nm 9mm lasers with a CC-Boost designed by rhd and lpf. I was setting the current when I realized I goofed. Instead of a single 18650, I had put in two 16340's. Here's the weird part: it worked pretty well. No smoke, smell, or any fried circuitry...

Hello, Selling a refurbished laser for cheap. No huge problem with it, but the tailcap blew so I ghetto rigged it and it works great. It's very fun, and very compact. Great for use as a pointer or pocket burner. *FIXED* $90 shipped CONUS PM me and post if interested...

SOLD Hi guys, I built this laser a few months ago, and although I love it, I am putting it up for sale because I want to buy some other things and I rarely use it. It is a great laser. The host looks amazing, and this m462 diode is one of the more efficient diodes I have seen on the forum...

(Edit) Summary of thread: I set the current too high (765 mA), but the diode was fine until the battery voltage sagged and put the flexdrive out of it's specs range, and that is the believed cause of death. Even with initial input voltage of 4.2V, the flex was technically already out of it's...

So I am planning on building a pair of m140 diodes into a couple relatively small hosts. I found this DX driver (actually 2, which is an added bonus). I also like the current, at 1400 mA because it won't push the heatsink's capacity too much . I'm not sure about the 5 modes, if the 10% one...

Hi all, I have been working with blue lasers for over a month now, and now I'm looking for a change. So, I got a 500mw Mitsubishi 638nm diode from DTR. This is my first attempt at a red laser, and I'm not entirely sure if this diode is compatible with my 1.25A driver from survival Lasers...

I recently built my first class 4 laser, and it works, but barely. I ordered parts from DTR and Survival Lasers. I have a Diy c6 with an adjustable current driver (1.6 to 2.3A), aluminum pill, and copper heatsink from survival. I used an m140 with a 3 element lens from DTR with 2 rcr123a...

New member here! Hi! It's great to be here! I just built my first class 4 laser (it wasn't a total success) and LPF has already helped. Anyway I live in Houston, and although I probably won't be of much help to anyone, I would like to learn more about Lasers.
