A new "Photino" 465nm @ 5W






Re: A new "Photino" 465nm @ 4.5W

As a heads up, the long metal sides are not in the heat pathway as best I can tell.

It's a pretty ugly package for sure. TBH I'm not sure I want to spend that much money now on something I could most likely damage during extraction and especially when the current module it's in isn't that great for heatsinking for longer run-time/higher power :undecided:
 
I had a chance to properly photograph and LPM the 465nm "Photino" tonight. It peaks above 5.2W (briefly).

At 5.2W of 465nm, this is certainly takes the prize as the brightest, smallest, blue I've ever made (possibly that I'm aware of anywhere in the wild). This is certainly my favorite personal build.

New photos and video in the OP :)

Can't say I've seen a video where beam brightness alone flares the camera's lenses enough for it to reduce overall brightness of the capture.

Do we get some shots of the insides, build details? What lens are you using that it has such a thin beam profile? What battery is small enough to power this?

Sure, subject to a bit of blurring of it's "fancy bits", here's a shot of the general structure (this is one of the earlier Photino prototype builds, so it's a bit dirty / industrial looking):

I'd assume those are two small lithium polymer packs on the sides?

Why the blurring? I mean, it's not like somebody's going to steal your laser or the idea. You've got proof right here (time stamps on posts) you built it first. Besides I don't think I've ever seen a dispute over ownership of laser's internal construction anyway. So I'm a bit confused here.

Just blurring the driver a bit, that's all. It's a special one. I haven't released that particular driver at this stage.

Edit: Yep, that's two lipos, very small ones. Standard 12mm module. 5A capable buck (the pictured build was probably set to 500mA, because I tested with 650nm single modes). 2S balance charging port integrated into the driver. Tactile button board.

5 Amps buck driver, huh? That explains it, two lipos are in series, and bucking it down to diode's voltage gives you some runtime.

How much amps is the diode actually pulling?

Charging port is badass. I assume the charging circuitry isn't in the case of the laser, right?

All in all very nice build. Power/size ratio must be the best I've seen so far. I mean, 5 Watts, wow. :D

The diode is actually seeing 4A of current. This build gets hot (not warm) in about 10 seconds. One of the neat tricks though, is that because of its flat undersurface, you can set it on a metal desk / piece of aluminum, etc, and it very quickly cools the build down again. I've though about making a "docking station" for my photinos that would work somewhat the same way, and provide for a more realistic run time with additional external cells.

The charging port is just a raw pinout of the 2S leads (so the + of one cell, the - of the other, and the point of intersection). It allows for charging with a typical 2S hobby charger. It would also make it relatively easy to create a docking station.

That'd be neat...Maybe a similarly themed (visually) actively cooled custom aluminum block that you could plug all the photinos into at once either just for charging or for using. Could potentially even have a small AC-DC coverter on board so the whole thing could just be plugged into mains. A sort of "mothership" if you will :p
