    Alternatives to DTR for NUBM44 modules?

    I emailed DTR on September 9 for information about the purchase of a NUBM44 module, and he hasn't answered yet. His last post here is dated September 5, and his last visitor message, dated June 12, ends with " when ever you can get back to me that would be great!" DTR has (or... had?) a great...

    What's a reliable source for 18650 batteries that ships to EU?

    LiIonWholesale only ships to North America, unless the orders are for 500 or more batteries. I'm in the EU. What is a reliable site to buy the correct number (how many?) of 18650 batteries to power a NUBM44 diode? I've seen these batteries on Amazon (UK) but I don't know if I can trust that they...

    What is this set of optics used for?

    I've been reading about the NUBM44 diode, which is very powerful but has a highly divergent slow axis, and I've been suggested to use this set of lenses to reduce its divergence. Premise: I've never dabbled into the optics part of lasers, only into the burning part. Well, it's never too late to...

    5W 445nm labby from OdicForce: did anyone try it?

    This laser: 5W 450nm Blue Focusing Laser Module (12V) with TTL Driver - OdicForce - I noticed the title says 5W, but the description mentions "4+W". So, has anyone measured its actual power with a meter? - What are the dimensions of the driver? The picture only gives the dimensions of the laser...

    Where can I get first-surface mirrors?

    Okay, so this post is not strictly related to lasers. I need a first-surface mirror (1.5 mm thick) to repair an old head-mounted display from Virtuality, which uses a pair of acrylic first-surface mirrors to reflect the images from the displays into the lenses. I had to remove the right-hand...

    Has there been a law change in the EU?

    I've noticed that OdicForce doesn't offer 1W handhelds anymore (the highest power available right now is a 1W labby), while Blord hasn't posted anything for over a month, not even to let laserdonkey know if he's alive. This could be a coincidence, but it could also mean that laser laws in the EU...

    A piece of laser history... or a memory to shattered dreams

    Check out the article I've found: Build your own LASER! | Modern Mechanix It appears that the November 1964 issue of Popular Science had an article that taught people how to build a ruby laser. I wonder if anyone reading this forum was already around back then to attempt such a build (or...

    Visions from 2001: Saturn and Beyond the Infinite

    One of the science-fiction novels I read as a kid was "2001: A Space Odyssey". As I read that for the first time, I could see in my mind the astonishing imagery of the inside of Jupiter being filmed by a probe, of the moons of Saturn, of the TMA-2 monolith on the surface of Iapetus, of the Grand...

    My Commodore 65 emulator

    Yes, the 65 in the title is not a typo: there is such a thing as a Commodore 65, and I have just released the fourth version of Hi65, my high-level Commodore 65 emulator. That machine has fascinated me since I got aware of its existence (that was about in 2002), and for years I have waited for...

    My Dominator has died

    Yesterday it was working perfectly, but when I tried to use it again today, it just won't switch on anymore. I have tested the switch, and it works, the batteries are charged. Here's a video for proof: (EDIT: I removed the video because the problem has been solved) Just in case, here's what I...

    My experience with Blord's 3W Dominator (and a surreal repair)

    About a week ago I ordered a 3W Dominator from Blord, which arrived yesterday. The first things I noticed were how heavy it is, and how the focussing ring at the front appeared to be much better coupled than the focussing element of the 1W laser I had bought last year (I could notice no backlash...

    2x 26650 battery holders: where to find them?

    I have this idea of buying a Dominator from Blord and using it to turn a prop raygun into something... more active. ;) But to do that, I will need to insert a pushbutton between the driver and the batteries, which I won't be able to do with the batteries inside the host. But do 2x 26650 battery...

    Drivers for 808nm lasers: where are they?

    Some sites, like O-Like, sell complete 808nm laser systems (diode, heat sink, fans, driver). But what if I want to buy the driver only? Googling "808nm laser driver" got me some results on Ebay, but those drivers only go up to 1W. So, let's say that I want to power a diode like this. Where would...

    Would you trust this seller?

    "Win-Win-Mechatronic", an Ebay seller from China, with 99% positive feedback, is selling a 40W CO2 power supply at $110 and a 40W CO2 laser tube at $120. Has anyone here ever done business with him? If the answer is yes, what were the results?

    Why can't I search for "o-like"?

    I tried to use the search function in order to find all posts containing the word "o-like". However, what I get is "Sorry - no matches. Please try some different terms." which of course is completely wrong. Why? My hypothesis is that it happens because of the minus sign, for which the system...

    Ever set anything on fire... unintentionally?

    It just happened to me, while I was trying to burn a hole through a cardboard box with the 445 I bought from OdicForce. When I switched the laser off, I saw little pieces of burnt cardboard glowing like embers, which I was used to see, so I thought nothing of it. After a few seconds, however...

    5W IR from O-Like: is it legit?

    I've been browsing the O-Like website recently, and I found a page about what they claim to be a 5W 808nm laser. My first (emotional) reaction: "OMG 5W SO MUCH BURNING POWER!!!11ONE" (yeah, so I can get pretty emotional :D ) My second (rational) reaction: "Hold your horses, remember how the old...

    My purchase from OdicForce

    Last Tuesday I had placed an order to OdicForce, for the following: - 1 laser (445nm, 1000mW) - 2 TrustFire batteries (3.6V) - 1 TrustFire battery charger - 1 pair of Eagle Pair glasses The parcel arrived this morning: I'm really surprised how fast the shipment has been. The host of the laser...

    OdicForce - how long do they usually take to answer emails?

    Three days ago (October 7, 2012) I sent them an email to ask them some questions about a laser module they sell. They haven't answered yet, so I need to know from whoever has already dealt with them: how long do they usually take to answer emails? And in case I decide to order something from...
