Hotlights PHR at 106mA

[Elektrotechniker]

So I had a blu ray diode pressed in a module around and thought I would make a low powered phr build. I did build the driver on my own, using etching solution and cutting the final piece with a dremel. The original idea is Eudaimonium's, who pointed me to the right components. The driver uses a lm1117, a capacitor and a resistor( I don't remember their values, sorry ). The driver is powered by 2 lithium cells and is extremely stable at 106mA The only problem is that the phr only outputs like 90 mW ( peak ) and averages at 90mW as well. It's not as bright as my last phr build iirc. I dont have another working PHR to compare it, so I guess it's kind of underspec? I am planning to add a pot to take the current up to 115mA to achieve a better burning capability. The heatsink of the hotlight kit is more than enough for a diode like the phr anyway. Well enough with the speaking, here are some pictures I took while assembling the laser, as well as the DIY driver.

Driver

Assembling

I only used the + power input of the driver since I shorted the case pin to the diode negative pin( to achieve the - battery connection ). Soldered the metal ring of the host to the driver + and that's it.Then I just ran a wire from the + driver output to the diode anode. Wrapped the driver with some blue electrical tape( i love how it matches the color of the body here ) and pushed the driver above the metal ring where I soldered the positive wire. I screwed the head to the body while making sure the heatsink did not spin( spinning might break a wire connection and probably a diode pin ). Here's some pictures showing what I described.

Basically I am happy with it because I did build the driver from the ground up, although the diode seems to be underspec. It was a very cool DIY experience. I ordered 2 pairs of 10440's because 2xcr123's won't fit in the host.
Tell me your thoughts
P.S sorry, i did not take any pictures of it lasing, nothing exciting to see from a phr Oh, and a great thanks to Eudaimonium for the driver idea, to Mohrenberg for providing flaminpyro wire along with the kit, and to Flaminpyro himself This wire is the best i have ever used. The best stuff for laser work

Nice and simple!
This is the exact same build that is awaiting me in the very near future!
Except I'm scared of soldering SMD components.
I'm still worrying about the batteries though, looks like I'll have to get a couple of 10440
and cram them into the AAA holder.

Oh, could you please resize the pictures a bit? I have to scroll left and right to read the text.

Thanks Pics resized to 1024x768. I figured that 1280x960 would be an average so everyone can see it. Lol I guess not.

Nice Work Buddy. :gj: Especially the Driver looks great. I love those little LM1117.

I think at 90mW at 106mA is pretty much on point. I had my PHR set to 128mA and it was doing a little over 100mW and now its doing right on the money 100mW. So i would say anything between 90mW-100mW at 106mA currant is on point.

You have a really nice camera too.

+1 For you.:beer:

Thanks for you kind words and for the +rep
Yeah I love the work I put on this driver It's actually very encouraging to see that something that has been made by your own hands powers a laser diode !
Maybe I should be doing more DIY from now on. The camera is a KODAK Easyshare MD1063. The pictures of the driver were macros and a lot of zoom had to be used, that's why they appear a little blurry. Other than that, yeah, it's a nice camera :beer: So i guess the power I am getting is normal. Still, I want to push this a little more :evil: using a pot. You know what I'm talking about

 

[Leodahsan]

I want the lasing pics. :cryyy::cryyy::cryyy:

oh btw if you want some MACRO photo tips without suppa expensive camera/lens, pm me.

 

[Elektrotechniker]

a quick one. No exposure. The dot has a big circle around it :O I don't know what it is.

I will also do some burning tests with matches in a bit and post the results.

 

[Leodahsan]

:O looks like you've tested the burning potential with your potential computer subwoofer :crackup:

Teh circle looks like lens crap..

Yeah I guess I'll have to clean it up. And I don't think is a "subwoofer" anymore; it's ON the table :shhh:

 

[Leodahsan]

Oooh, so it is a Overwoofer (or Onwoofer as you said). Sorry my bad :shhh:

No, I mean that its meant to go under the table but I left it on it

 

[Leodahsan]

ooooh... triple lol anyways.
:beer: +1 for your build (and honesty ) by the way. Waiting for more pics.

 

[Elektrotechniker]

Yup, it burns like a charm in less than a second I will upload a video later

 

[anselm]

Yes, but.....
Can it pop a balloon?

 

[Leodahsan]

Finally u learn't uh?

 

[Elektrotechniker]

I guess lol. I dont have any balloons now though. Well friends are amazed by lighting matches. They wouldnt care at all if it could pop balloons. They find it "more powerful" if it lights matches :crackup:
