New PHR build with Boost converter

[Eudaimonium]

Hiya all LPF folks,

Here is my first practical application of LM3410X boost converter I am developing...

Let's keep this short shall we?

PHR diode, Acrylic lens, boost converter set at 96 mA (was going for 100, oh well ), power output measured 81 mW after lens

Thanks to Bill:
Host
Heastink,
Diode
DMM
LPM adapter for DMM

^he is the man!

Anyhow, this was supposed to be a 6x build with SF-AW set to 160mA, however after a bad incident involving a tiny bit of alluminum from HS sawing, both the driver and SF ended up fried. Don't ask.

Well, it is a sweet little build that can use either 1x 14500 lithium, or 3x AAA in their's pocket. Works just the same.

Anyhow, a picture pillar is in order...

You can see the driver soldered to the diode, and a little spring on the back that serves as BATT+ connection.
Batt- is the entire host, through the alluminum HS and diode's case, which is not connected to diode + or - .

Entire things pressfited into HS.

Everything in order of the assembly

^pocket cam, all colors go haywire when laser is being photographed...


And here is a little video demonstration of the laser.
Enjoy!

Nice build driver looks great as well.

Thanks!

And thanks! I got it after 5 edits... :crackup:

lol, yea I remember doing the same thing a while ago, it can be a pain in the ass.

I don't know about your display setup (monitor, graphics) guys, but this is one hella realistic beamshot I just took

Enjoy!

This DMM is soo gigantic

btw...I'm glad to see LM3410X working well

Hell yeah, it has the 'Weather tomorrow' and 'Winning lottery numbers' on it's dial.


Thank you Bill!:bowdown:

LM3410X is working beautifully, I will make same drivers for all my lasers in the future, both bluray, and red.

DMM is looking good! Nice looking and nicely made driver. The laser is compact, and it's nice to be able to use lithium or AAA power. Should be no heat issues with that heatsink. Excellent work!

The man himself!

Thanks so much for the entire DMM/LPM setup, you really shouldn't have.

Thank you for kind words on the build, I really wished that a 6x would be lasing inside, as originally planned. I am sorry about that more than you know :cryyy:

Well it is nice build after all, disregarding the original plans and intentions.
Compared to pen build I built some time ago, this one is a 'tad' more visible... perhaps a bit longer wavelenght diode?

Well, the driver you see is the very same one that will be in your Aurora , Bill!

EDIT:
Hmm I am looking through original post... I seem to forgot the image of the back side of the heatsink, where a spring is visible peaking out.
Anyhow, the spring is shortened exactly to the lenght where it makes a nice battery connection, but the excessive pressure from the batt does not transfer to the diode's pins because of the heatsink which is hit by the battery.
I need a matching set of those...

Sweet build, and congrats on the driver. That heatsink is awesome :gj:

 

[Eudaimonium]

Thanks dude, HS is by billg519 again...

Made to fit this host!

I'm a bit concerned bout the fins on a heatsink that goes inside a solid host. If there were holes in the host then it wouldn't be so much of an issue, but those fins are creating nice pockets of hot air that is then trapped inside teh host. When I first saw it I was like cool host but then it went inside and I was like aaaaaaah

You are right...
I can always remove the laser head from host in two seconds to allow it to cool off, but I don't think it is neccessary.
I didn't even use it that much, and it does not produce enourmous amount of heat.
It is a simple PHR after all...

Thanks for the tip, when I machine heatsinks it is much easier to simply leave it solid.
Well each one of the fins touches the host body so there is a heat tranfer to some degree, but I didn't even allow for it to heat up.
Quite chilly outside, these days...
