Even cooler with a 5x expander! Thanks @Z80 Lasers!

Nice monoheatsink! This should match really good with the cooper S2’s! How is it fixed? I have some high powered builds on Convoy S2’s: (and a lot more in the >2W range) - Nubm0C @5.8A on a smooth copper S2+ (~6.5w?) - GH04C06V9G @6.2A on aluminum S2 (~10w?) Both are using the full DTR 20mm...

The 93 grams of copper that sink the heat of this thing for some seconds before it’s too hot to hold 🤣 Also a comparison with my purple twins and a Survival Laser C6 host.

Things gets interesting with an expander, the threads to attach them were the biggest goal for this project

Another Qualas build, this time using a Nubb24t submodule. The Fan shaped beams were fun, but what about going parallel for this build? Build summary: - Unsoldered the submodule from the Nichia module, I kept the original lens array this time - Reflowed the 4 LD’s submodule in a 20mm DTP...

The B64B70 bin looks interesting! I’d love to see how much it will shift up with some overcurrent

Very nice! Is the diverge the same as the 10w?

Found some 3W 425nm pointers on AliExpress and got thinking what could be the diode used on them. Them I found a cheap GH04I01A2G and decided to try over-current it as I think this may be the diode, calculated about 1.5A for the 3W and gave a try! No issues so far! I really liked how the...

More things that Polyboost is not: - Compatible with illuminated tail switches, they get crazy! Had to change plans and identify the RGB collection with colored buttons. - Suitable for common cathode setups, it only work with LS current sensing. I’ll need to work on a variation with HS current...

My multi-beam RGB collection is complete, all of them using Polyboost driver (: More details on the individual posts. Blue Penta-beam: https://laserpointerforums.com/threads/blue-penta-beam-pointer.112067 Red Octa-beam...

Build and beam shots. Collimating this one with an D20mm FL15mm lens. Polyboost is pushing 1.3A and I think ~13.5v here.

The Numb12t is composed of 2 submodules: - 4x2 reds (used on the octa-beam) - 3x 525nm + 2x 465nm I decided to use the second half on this project with the blues dormant to create a pure green multi-beam. I was not that excited with just 3 beams and was also expecting the greenies to be the...

Three peaks as expected for this red array, a little bit higher than on the spec: 641nm, 645nm and 649nm (2A and probably hot) One of them looks a little more pinkish and dimmer, all other are almost the same to my eyes.

Not much variation on WL between diodes with one peak at 454nm (500ma)

Some build and beam shots

Of course I would not stop on the Blue Penta-beam after all the effort put into Polyboost! My Numb12t arrived and the reds beams look really awesome behind a long FL lens (: But lots of artifacts to try cleaning out… Stay tuned for the build.

Getting some more ready for the next projects :)

Already landed on this thread a couple of times!! Pretty cool! For sure it helped with the inspiration over the years!

I was able to use the same hot plate I use for reflowing the driver boards and led emitters on mcpcb’s. I just transferred the module from the original board and dropped on an already pasted 20mm copper star board for 9090 leds. Then it went to the hot plate again, centralized by eye and let it...

Still looking for a better lens, any suggestions anyone? The size that fits on the body is 40mm/36mm (with and without “collar”) and ~22mm FL. Edit: The masks I made in 10mm to 28mm size do work as adapters! This means that any lens on that size range with a “tab” and FL up to 22/23mm would...
