    A design for solid state precision touch control

    Hi guys! One of the aspects of our custom laser builds that I always thought could be improved is the fixed output mode circuitry that we have. I have been finding out about (not-so) recent developments in flashlight hosts which have rotary magnetic mode switches. This is a ring mounted on...

    X-Drive wiring questions

    Hi guys, I really need to get this 445 built today, but I am wondering about one of the details. I've got a pretty standard build going here where the diode case will be electrically connected to the battery minus in a 18650 (P60 style) flashlight host. I have used my DMM and it reports...

    Thermal impact of Aixiz modules

    I couldn't find a subforum for this topic so that is why I am posting in General. :) First off, I'm curious about what metal these Aixiz modules are actually made from. I'm worried about their ability to transfer heat from the LD to the rest of the (preferably aluminum or copper) host in an...

    How to determine the type of AR coating on a lens?

    I've got a few Aixiz 3-element lenses and they seem to be coated for different wavelengths. Are the ones that produce more bluish reflections the 650nm coated ones?

    500mw Mits 635: X-Drive, single cell?

    On the cajunlasers page of the 1.5A X-Drive it says two lithium cells would be good for the driver. I was hoping that since the diode does not seem to require more than 3V that a single 3.7V cell and a buck driver could be possible. Is it that at 1.5Amps that this will be difficult to pull...

    Ehgemus Host 2x14440 Build Log!

    Hi everyone! :wave: I wanted to build a very small, very high output 2x series 10440 IMR cell 445 burning laser. So I asked Ehgemus if he would be up for it. What I got was a host that wasn't quite as thin as I had hoped. Turns out it's practically impossible to fit drivers and clickies in a...

    Can the minimum voltage of a Buck driver be used as battery overdischarge protection?

    As an example the Lazeerer X-Drive is the buck driver I am using in my upcoming build. I notice on posted specs a minimum voltage of 5.6V. What is the electrical behavior as input battery voltage approaches this threshold? As my cells drop to 2.8V will the driver shut off? It's obviously...

    O-Like Crown 500mw internals

    I received one of these lasers. It produces a pretty epic amount of output but sadly the alignment of the internal unit is slightly off-center, causing a not-great beam profile and a decrease in output power when collimated... I have contacted Susie and have been given instructions to send it...

    Looking for super small (and preferably affordable) drivers

    I have made a few 18650 builds but I am now hell-bent on pushing the limit of 10440 powered lasers. There are many problems presented by trying to adapt AAA flashlight hosts into burning lasers, one of which is the space constraint. I've been reading about the benboost driver which is a...

    Hi all! I've been away a while.

    I got a job! Now I have lots of $$$ to play with lasers! I just ordered a 500mW Greenie from O-Like, the nice waterproof one. I'm gonna hunt for reviews for it now, if anybody else here has one of these (surely somebody has... it's priced so well!). I'll definitely take some pictures and review...

    Setting up LFI for projector

    My USB Soundcard is still in the mail. I'm trying to get familiar with LFI while I wait. I have my breadboarded correction amp ready to go. Here's the output I'm getting from LFI_player_log.txt: OnInitialUpdate(): Unable to instantiate output device 1 object. OnInitialUpdate(): Unable to...

    Using a 405nm laser to treat acne?

    Relevant link While reading about Propionibacterium acnes on Wikipedia I noticed a blurb about 405-420nm light being particularly sensitive for the bacteria due to the endogenic concentrations of coporphyrin III. However I am unable to find extended information on this compound. I have also...

    Has anybody built a heatsink for this host?

    Here's the host: Sky Ray G6 Manafont.com | $21.2 Sky Ray G6 Cree R5 5-Mode Stainless Steel LED Flashlight (1*18650) Found an image: I think it's pretty good lookin' but haven't found anybody mentioning it around here. I think it would be a sweet laser host. I don't have the equipment or...

    Sweet new custom HTPC for sale

    I figure there'd be plenty of computer enthusiasts among us so it wouldn't hurt to network a bit over here. I built this over the weekend. Tiny Gaming HTPC Sandy Bridge i5, GTX560Ti, 550MB/s SSD on eBid United States Compare to Alienware, Origin, etc. This is great because you get top...

    Readily available and free source for diode setting tools!

    On every single sled I have seen thus far, there are two little brass rings inside the part that I can only assume connects the sled to a rail. On the attached picture of an LPC815 sled it's on the bottom right side. If you take any appropriately sized tool to remove these little rings from the...

    Which direction to put 660nm glass lens?

    EDIT: Silly me. Both ends have the AR coating. I really doubt either way makes a difference. I got one of these for $10 from Kendall for use with the LPC diode but I'm not sure which direction to put the lens in. One side has the blue AR coating. Seems to me I should be putting this end...

    Groove 2 Driver Question

    Hi, I wanted to check in quickly to make sure I have this right. The groove 2 driver is a linear driver. This means that the current drawn from the power source is the same current that is fed to the diode. I ask because I do not have a test load yet and I don't want to fry my diode. I...

    Can window dislodged, should/can I decan it?

    This happened during the removal of the heatsink of the SF-AW210 blu-ray diode. I guess I twisted it too much, but I don't really see how I can get it out without a twisting motion. Actually heard the thing crack/pop loose. Anyway, I can try to see if it works as-is but it doesnt seem like a...

    Killing diodes by twisting the pin

    Anyone else have this happen to them? I'm surprised I've never read about this happening yet, because I am positive this is how I killed two of my diodes now (both LPC-815's i got from HighTechDealz). I soldered only the positive terminal because part of the pad on the negative terminal on the...
