1.6W Peak 445nm SS 18650 Jayrob host W/'custom 'Hot' option' heatsink on driver

[MeanGreen]

...I am in the process of getting one set to 1.7A in my 3405 host with two microboost drives running at 850mA and set in parallel. We will see how it holds up under that current.

I'll be watching out for that. :drool:

I'm very sorry I missed this before. A very nice review (and build)

You would need for the exact same build.
A diode and a Aixiz module. I used an A140 diode.
The SS 18650 Hot kit W/Flexdrive set to max from Jay
Options: copper heatsink, copper module, EzFocus Adapter and the heatsink upgrade for the driver.
I have both the 405-G-1 lens for burning/power tests and the 405/445 Aixiz Glass for pointing.
Then you just need a battery and charger.

Good luck with your build:beer:

Thanks a bunch, I really want to build this, but I am not sure how it will turn out cost wise, and I would hate to burn out a 50 dollar diode by accident

I will have to see what I do, then I need safety glasses, I already have a good battery and charger set. Does the flexdrive allow me to push about 1400mw~1600mw out of this laser, I mainly want to use for pointing, I love shining it like 2 miles away to see the dot back at me, just amazes me, but also burning would be fun, It doesnt matter if they dot is average size for burning for me anyone still selling the A140 diode? I saw daquin was, but is out now I think

EDIT

Just from looking you have the flex drive from jay, so wow, I will go add up prices on his parts, I really love that host, I canceled my arctic order, every order I see, or at least 75% of them, the laser dies 4 days after having it, and I can not deal with that.

Also, what is your duty cycle on that guy? can you go constant for at least 5 minutes? or like only 1 minute on it, I know having a copper heat sink would help a ton!!

If you want to use it for pointing I would suggest getting the Aixiz or O-Like glass. It will run with a little less power but the divergance is much better for pointing.

I just ordered some diodes from Daguin yesterday and his sale thread does not say anything about being out. LINK

You could ask in the thread or PM him.

ok, your right, he does have them in stock, so If I got

* SS 18650 basic kit - $55 (host/heatsink/drill the pill)
* Add 'Hot' option - $48 (let me know the current setting)
* Copper heatsink upgrade - $12

* 1/2" Custom Copper Module - $25 (is this worth it?)

Now do I get this one?
* Knurled EzFocus adapter (if desired) - $24 (designed for fitting my 405-G-1 or 650-G-1 lenses, but there is plenty of room in the heatsink for module positioning for use with different lenses)

Or is it this One?
* AixiZ 445 glass lens with AixiZ focus ring - $11 / Or with Custom Focus knob - $25 (see here: http://laserpointerforums.com/f64/fs...ses-51727.html ) (

From the looks of it though I would get the $24 dollar EzFocus adapter, and the $11 dollar AixiZ 445 Glass lens, and that would take care of that, so bringing the price to $150 for the parts, then $52 for the diode, and all the shipping. Thats with the custom copper module omitted from this calculation as I am not sure if that is needed.

The regular module definitely capable of handling the heat but I think you will get better runtimes with the copper and less of a power drop due to heat.

As far as the focus adapter.

It is the difference between:

A Clean look and very easy to turn.
EzFocus

An easy to turn and allows for a dust cap to keep your lens clean.
Custom Focus Nob

And a very basic and cheap. Requires you to have your fingers a little to close to the fire with this type of output if you ask me.
Aixiz Focus Ring

Thanks a bunch for the 2 other comparison pictures, that helped a lot, last question, what current would you have it set too, I want to push about 1400mw, I would like 1600 but I imagine that will greatly reduce the diodes life, so I could be very happy with 1400mw, or heck even 1200mw, but what would be the current amount that they driver would have to be set at, or can I just tell jayrob I that I want the diode to output about 1400 and he will set that up? I really want to do this, but I need to decide if its worth it, I want a powerful laser, and I am glad I got canceled the arctic order, the cool thing is this site is making me want to learn more about lasers and build my own, seems like It would give me a great feeling knowing I put this together

ok, so If I ordered this board http://hacylon.case.edu/ebay/laser_diode/Micro_BoostDrive.php and then have them set the current output, as I don't want to Fudge this up, that would save me a few bucks, I can handle soldiering the wires on there, but is the correct driver to fit in the little heat sink that jayrob makes?

I am getting close to 1400mW when I use my Aixiz 405/445 lens on the Beast.


You can certainly get the driver directly from drlava and save a few bucks. But you will need to solder battery and diode wires to the driver and mount it in the pill yourself. But with the tight nature of this build you can go with Jay's hot kit and he will solder everything to the chip and mount it for a nice professional look. And all you will have to do is press the diode in an Aixiz module and solder it to the connectors.

Yea, I think maybe I should just get it from jay, it would cost about 10 more bucks to have it mounted and all ready to go, would you recommend maxing out the driver at 1000mw?

 

[Kevlar]

Very nice DTR!!! Well thought out and executed!! :beer:

 

[cd520]

You get those drivers parralled yet at 1.7A??? Im very curious to the results.

 

[iFoSh]

I finally gave in and ordered one of these beasts...Thanks for such a great review!

I think the microboost can max at 1200mA and the Flexdrive if Jay has any left for his kits max at 1460mA. You could always set it at 1A and play with it for a while and when have had more time and experience you can turn it up later.

I just got my drivers today and will be messing around with them tonight. Keep you posted.

Here is the part where I am getting lost, I can't find the voltage that these diodes run at, I imagine that the flex drive or microboost will output the correct voltage and by changing the amperage it will cause it to output more power, but I can't seem to find what amperage put out what amount of power, because when reading the manual for these drivers I see settings for 1000 mw or so, but at what voltage rate and what amperage rate is that at, this is where I am getting lost, I would like a laser that could match yours or go slightly below like ~1200-1400mw output from the beam, but I can't seem to get what output from the driver would accomplish that, and I also understand dissipating heat changes things, but peak output for that would be great. any ideas on that?

 

[Morgan]

With the Flexdrive DTR achieved maximum output by simply turning the driver all the way up!

With an efficient diode you could probably get your 1,200-1,400mW by maxing out a Microboost at 1,200mA.
This link should give you some clues -

http://laserpointerforums.com/f65/list-445nm-diodes-51897.html

The forward voltage of these diodes is ~4.2V at the high powers but the driver will look after that for you by boosting whatever the battery voltage is, (assuming it's below what's required). The Flexdrive will buck voltage from a higher voltage source but a Microboost cannot be used that way and will be damaged by a voltage source higher than that required by the diode.

I hope that's helpful.

Thanks for the info, so I will tell jayrob that I want to have mine microboost set at 1,200ma and then I just gotta put this beast together! Do you think the aluminum heat sink will work good enough on the driver, or should I get the copper one, I would really like to not spend that extra 24 dollars for some copper, ha ha, also any idea on what my run times will be like? could I run this for 5 minutes straight with no issues?
