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...

Build pics

Close ups of the module being driven at lowest level I could get with Polyboost (in theory something <1% of 1A) I’m still amazed with the size of this thing! The diodes have only 1mm offset and are deflected by tiny little mirrors. All observable with a nice magnifying glass in front (:

Last year I lost my hopes on getting a GH04C06X9G for a multi-beam blue pointer, so I began looking for a multi-diode solution. After seeing how close the new Qualas modules have the diodes mounted, I decided to try focusing all of them with a single big long FL lens (: So I got a Nubb38t with...

I never updated this thread with the end result! I ended up extracting the diodes and pressed on 12mm modules, very easy because they were screwed and not pressed on the old 16mm modules. Thanks everyone for the advices! Those 3 build were the starting point for me to deep dive on the goal...

No heatsink! Why I’m not doing it?? 🤦 I’m not confident that this will make it handle the full 3A @20v of the Qualas, but it can help! I’ll be very happy if I get 2.5A at least for a couple of seconds with the extra thermal mass!

He makes very nice and solid pointers!! I really love my Micro Torch’s!

I was having a hard time searching high Vf boost drivers in a compact circular size that would fit in a flashlight body. At some point I was convinced that I would not find it ready to buy at the size I wanted, and after some tests with the TPS61500 boost controller I finally decided to learn a...

Interesting, they pretty similar but I noticed the Osram have a bigger offset between diodes (1.5mm) than all the Nichia’s (1mm to 1.25mm) Are the Osram attainable? I would love to play with this slighter bigger distance…
