A lot more purple-ish, but still noticeable bluer than 420nm. For me 420nm is almost as violet as 405 but a lot more visible, 425nm is still not blue but it already start looking more like a 430/440nm that still have some purple hints. On 450nm I really don’t see any purple anymore. Another...

I’m always testing the modified drivers with a scope before wiring a LD. The 2A, 4A and 5A boost drivers all looks good! I cannot say the same about the buck drivers, already fried a double emitter red with an unmodified driver and never got to trust on them again. The convoys 7135 drivers are...

Are you planning to mod the 2a boost driver? It comes with a 20mohm shunt for 2a, those have a inversely proportional relation. 40/X formula will give you the output current in amps with a Xmhom resistor. Expected output: 10mhom -> 4a 20mhom -> 2a 25mhom -> 1.6a 40mhom -> 1a After the...

Some beam shots of the Kyocera SLD module with the Z1 22mm FL lens. I’m thinking if a shorter focal length could actually increase the “white laser” effect here by having a smaller initial beam diameter even if divergence increases… I’ll try to get rid of some of the spill with a black gasket

Holy shit, crazy to find this thread just now! Was googling for a ref on the Kyocera SLD that I just added to the poly beam collection where all other builds uses those micro arrays!

One more Polyboost build still using a Convoy Z1 host. Probably the last one of this collection. This time it’s not exactly a laser but have two visible blue laser diodes aiming at a phosphorus layer: https://budgetlightforum.com/t/convoy-z1-lep-emitter/232819

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)
