The "SXB-2" (Super X-Boost) 3A+ Boost Drive for 9mm 445nm diodes

Leodahsan said:

I understand that, Angelos. I haven't played with the 9mm diodes yet...

But I'm planning something that would make use of a simple TTL... Something simple, like @ 50ºc = red led, @60ºc = TTL 0v = laser shutdown. But thats not the place for talking about this

Can your driver have that? TTL mod?

How to check if what you want can be done on this driver.?

There is Logic.

I dont know anything on TTL.

@Grainde I will check for you later but if your saying your running them at 5A+ then that should not be an issue off a 4.2v cell. Though again let me check to see before i can confirm. It should be above the load + drop at those currants.

I tried a regular XML at 3A and it was to low of load to use with 4.2v but these XML you show me seem to be able to take more currant there for a higher load and should work just fine.

Yup the XM-L2 versions run at a higher Vf than the old XML's. The problem I had, even with a good AW IMR battery, was the voltage drop ie @ 4.5A the battery voltage was droping from 4.2 V to around 3.9 V, which meant that was the max current I could get whilst direct driving the emitter. The internal resistance of my bat was 70 ish mOhm...:beer:

Such a beast driver, :gj:

With us pushing diodes at 3+ amps at high voltages, I guess a single 18650 won't do it anymore. Perhaps we should move onto parallel builds or even 26650 cells?

Maybe something like a sst-90 or even sst-50 for sure.

I think an SST-90 can handle more current, at the range of about 9-12A. :eg:

Yea I know... but some of those cheaper binned will like that current just fine without the blue hue givin by running the dog snot out of them.

I would not run that XM-L2 @ 6A they are fine at 3-3.5A IMHO.

Guess Im :eg: I really enjoy watching them scream with big lumps of copper:evil:

@ Ryansoh yup I think some parallel battery config will be called for to keep the current drain per battery to more managable levels... :beer:

Thats what she said :na:

The driver looks like a Bugatti so smooth like butter.

Angelos, you are the man! :gj:

These new SXB drivers are top notch! Just like all your stuff...

Here's pictures and build notes on my personal build using this new driver of yours.

Must have a high quality cell as mentioned. Especially if going over 2 Amps...








Note: If your going to go for an SXB driver set at 2.3 Amps as pictured, it will put a huge current demand on your 32650 cell to boost the 5+ voltage demand. (over 4.5 Amps)

This means that there will be voltage sag even with a fully charged cell, and because of that, the voltage monitor will be showing blue (or cyan) only for a short time after full charge, and then 'green'. As seen in the beam shot picture...

So I'm recommending a protected cell or a voltage monitor...

Voltage monitor color code:

* Blue - full
* Cyan - very good
* Green - good
* Yellow - low
* Red (or flashing red) - time to charge

My personal build shown above.

Notes:

9mm diode and stock 9mm lens
SXB driver at 2.3 Amps
2.6 Watts (sure wish I had a higher efficiency diode for this one)

One other note. In case your wondering why I have the front like that. It's because I like to have a dust cap for the lens. And also, I don't mess with the focus too much...

SXB driver FTW!!

Hey thanks guys. Iam glad you guys all like it.





WOW Jay.:drool: Thats AWESOME.:bowdown:

Thats a perfect setup for a 9mm diode.

Yeah the set screw is Fine. Its a Nice touch and i like it better then using thermal adhesive as like you said you can take it apart. No need to Thermal Adhesive it in. Thats a pretty big heatsink for the driver. But even if was a 1/4 of the size you still will have been OK. Iam sure you noticed the driver does not get all that hot very quickly.

As long as the driver is Heatsinked to a piece of Metal You will be just fine. The Set screw addition is Just a bonus. You can use Paste instead of adhesive with the set screw and it would pretty much have the same effect as thermal adhesive or very close to it.

Great Build.! I love that look.


When you going to send me that Mag build you wanted you know what done.:shhh:

Why don't you just steal all of my reps!!! It's beyond me how someone can be so creative and just share this with anyone who wants it. You're like the Santa Claus of lasers dude. +1 when I can.

Yes your right, I think the driver heatsink I'm using is over kill for that driver...

But I had room, so why not? And if anybody orders a build like this from me, I'll mount it the same way with the large driver heatsink.

About that build I wanted to send you, it wasn't a Mag build. It was my Lasever 473 build with a custom head, but a black host that would look cool if you put your awesome polishing skills to the host! (the fins look like a pain to polish)



I would just remove the head and send the host if you can do your thing with it??

I know you have been really busy though...

P.S. I'm ready to stock a few of those awesome SXB drivers! (awaiting your return email)

Hey guys!

Here is my SXB driver. It is by far the most well built driver i have layed my eyes on. I have yet to see it perform but i recon it wil do awesome!







greetings,, :beer:

According to the first picture, the LD+ pad solder is also touching the little component next to it, Is this supposed to be there, becuaue my wire snapped off when i first got my SXB and i am having MAJOR trouble getting a wire back onto the pad.

Like, im freaking out lol cause its my first 9mm build and i don't want to mess it up

Well i don't know this was wiring it allready came with. Then again the entire driver shorted and started smoking when i hooked it to a testload for the first time yesterday. I have no clue what happened. I am asking angelos for clarification but he has not come online yet.

Yesterday was a terrible days in driver world for me

Greetings,,

EDIT: angelos tests his work before shipping so 100% something went wrong with my setup. Now for the question what
