Yes, ended up rebuilding every unit that I had used that driver with. There is one build test above that used the old 1.25A Mohberg linear which also had issues holding a constant current. The driver was designed properly but the current set resistors that were underrated for the current they...

Went digging for a thread I remember Daguin did but looks like the photobucket BS strikes again.:( https://laserpointerforums.com/threads/the-improved-and-the-greatly-improved-arctic-mod.61956/

Here is an old pic I used to use to explain best how to not burn your sensor and collect the most power by going past collimation.🍺 Hell 30 seconds would be a huge improvement over just a pic. If your units is still running pretty stable at 90 seconds sure you can probably stop there and...

That is awesome. You are making some of the best looking units I am seeing these days.🍺 A few notes and don't take it as me poking at you specifically as you know I love the stuff you are putting out but based on the power test video it shows the laser can run for a total of 10 seconds before it...

Yep I could probably go back and find the old timers giving me the same lectures as I loved nice peak readings when I was a new and gung ho for more power and staying on the top of that 445 chart. Can still hear Laserbee correcting me on the distance from the sensor. It may have felt like he was...

Due to a recent product review on an engraver head that the reviewer could not get to cut and engrave different materials at the rates advertised. I think there was an issue with the lens being contaminated during the testing but the reviewer did correctly call out an overstated power rating due...

That is the real part number for the diodes I sell as NDG700. I named them that as i did not know what the part number was when I first got them and did not have a fake datasheet for them. This is the oldest batch I could find in my archive. 6/15 Production https://imageshack.com/i/pmlC59Gpj...

Styro I could not have said it better. I would never want anyone to feel discouraged about sharing their experiences about anything as that is the value of this community. Even if it is when I drop the ball which I do occasionally. It happens to everyone and I believe when it does it is all...

Yep on the NUBM44-V2's in 20mm with ACS5500BU using one of SL's 20mm adapters just wire the positive and negative leads from the module to the appropriate contact points on the contact board in the pill of the host and then place the 20mm flush on top of the host body minus the adapter. Then...

AWESOME.... Great work both you guys that is epic.🍺

Sorry I have not had a chance to go over it all with you as there were quire a few things that I was going detail about your setup and what you have experienced. I am guessing you did not notice that I did send you a credit for the diode which was your main request as you were going to just get...

Took a double take on that one as thought his listing meant M7 threading. Was trying to compute how that was going to work with a lens element that has a 7mm diameter already.🤔 G-2 is 6.3mm diamater and a good fit for the M9 barrels already. Anyway...

Not sure about the 304's having Axiz comparable lens threading and might be a pain to swap out. On that you would need to ask Sanwu as it does not say on the site. Might have the top which acts as a focus ring glued on the lens with a stop so it can not be fully unscrewed to discourage...

Nice. Quite partial to the tiny hosts myself. Very similar to the build in my sig.:cool: Here is the diode. This is one of my favorite diodes. Makes a nice tight beam/spot that is pretty bright. I do notice a lot of shift on these when pushing hard. I usually run them around 275mA or little...

The lens elements on those two are mounted in threaded barrels for compatibility with the common Aixiz styled laser diode mounts/modules(M9X0.5mm). This give them the ability to adjust the collimation and they will just unscrew to remove them and screw them back in to install. This part if you...

Whats up Mike.🍺 That is strange. When did you get that module and what size diode is in there? Glad you like it with the 2W blue. Great pass efficiency while giving a lower divergence than the other singe element G variants is great. Plus the best feature they sport is getting rid of the box...

Here is a little dye reflection montage. The green is the most noticeable due to the higher relative brightness compared to blue and red colors that are available as direct diode lasers..

Good fun. MIght be able to last a bit if using a driver with a slow rising start. Lazeerer made some drivers for pushing the single mode 405's back in the day. On the wavelength If I remember correctly It seemed whenever I would see testing of the BDR-209's and BDR-S06J's they were reporting...

The main differences are the TTL option on the SXD and the ACS units have no components on the underside designed to be flat mounted for heatsinking the driver. The SXD is mounted via the 8 pin chip to heatsink it. No difference with that configuration. Both will deliver 4.5A to the diode...
