How to drive the NUBM07E LD

Hello All !!
.
I need to drive the NUBM07E to about 4.4 A and need analogue modulation to control the output

I wanted to use the H2S dual driver from LSP. Dave noted that the drivers should not connected in series.

Before my email exchange with Dave...I was assuming that I would use a series connection arrangement....with each of the two drivers on the H2S unit providing 2.2A a piece.
.
But...he sez no ! OK...Anyone else out there using the H2S to drive the NUBM07E ?? In some fashion. did you connect both drivers on the board ? How ?? In a parallel arrangement ??...using balance resistors ???
.
Finally....What other driver has anyone used to power up the NUBM07E. This LD is current hungry and I want to supply 4.4 A @ 5.0 VDC as a maximum.
.
Any suggestion will be greatly appreciated !!!
.
Thank you,
CDBEAM
.
Note: Wow...Just checked Ebay...many new drivers out there...X-Wossee, Lasertrac, Optlasers and Ricktrent...Anyone have ANY comments on these units ?????????????? I have had experience with Opt Lasers and Lasertrac....they have great quality !

Hey Robert! :)
I have connected 07E and 08 to a badpip driver (Dual channel). Both channels paralleled and it works good. Up to 5A.
It also works good in Flexmod driver at 4A (Tested!)
It seems dual channel Lasertack driver is also capable to work paralelled, but not tested.
More options...

Optlasers 0-5A Lite LPLDD, no SBS however
Cheers!

If I recall a P3 will do 5A. I have a couple if you want me to ship ya one.

Hmmmmm ???? Thanx Jody !!!
.
Well...Perhaps I will try a parallel hook-up with the 07E using the H2S from LSP???
I already have the H2S mounted....so...the easiest solution is to use it....if possible !
And...I forgot Lasertrack....they make very high quality items !!!!
.
This 07E is part of a high power Lumia machine I am building !! Not your standard Lumia. !! I have been working with
Clickamouse on this project ! Super slow speed, Music linkage and a few other goodies. Go Big or Go Home !! HAHAHAHA
.
SOoo....I will try a parallel arrangement....with each H2S channel supplying a max of 2.2A...Thankfully...2.2A is the MAX output of each channel....so...I think I am safe to not overdrive the LD...well...overdrive is a relative word !! OK...Not overdrive past 4.4A !!
.
We will see...I will report back here... Thank you for your very quick reply !!!! ...for once I get started...or restarted on a project....well....l am obsessed !!!...and this Lumia Machine is now consuming my brain !!! I want to stretch the envelope on this Lumia project....well...maybe...
.
Just about the time one thinks they are the " first " to do something....well....typically...one finds out that this was done...years ago !!
Oh well....keeps me humble !!
.
Thanx,
Later
Bob

John.....You have returned !!! I knew you would !!! " Coherent light " is eventually compelling !!! Jems are a great interest...but...they generate no light...just reflect it !!
.
Anyway....Thank you for your offer....I may take you up on it !!!!!! The P3 is a standard !!!
.
You will be interested in my adventures into Lumia !!! I have several more Lumia generation ideas...beyond the unit I am working on now...brewing in me head !!!
.
Honestly....I think ...Lumia with modulation and novel beam combination techniques ( Not my idea...see DSLI-Jon ) are a very ripe for harvest !!!
.
We will see...the proof is in the " Video "....and the Winter months in Michigan a prime time to build !!!...as you well know !!
.
I will try the parallel wiring with the H2S...and see what that delivers !!!
.
Thanx,
Bob

Ups sorry, yes 5A P3.
If you re going to parallel HS2 try with dummy load first!

Yes...I have a nice and big Dummy Load unit made by Lazereer...and I will check First !!! Hate to smoke a beautiful 07E !!! Will post what I find !! Just another adventure !! Thanx,
Bob

Howdy CDBEAM!

I've purchased about a dozen different types of drivers and after testing, I found significant flaws in just about all of them. Dave's is decent but as you describe, doesn't meet your requirements. As Jors pointed out, I'd check out BBE's (AKA X-Wossee, AKA Vladimir) offering.

http://www.ebay.com/itm/162291013120...%3AMEBIDX%3AIT

I've been crowing about his 3A driver for months now and have replaced nearly all my drivers with this model. It's feature rich and has no errors that I can identify. Add to that, its dirt-cheap! I only have one of the 5A model (and four on the way), but I haven't pushed it to its limits. That said, considering well the 3A is working, I'd think it worth the US$32.50 to try the 5A version for your project.

I would not recommend the P3 with beam suppression. Although I have had reasonable success with the P3 without beam suppression, I have had a dozen or so failures of the BS version of the P3 including failure of BS (!), erratic output causing sudden death to diodes (!!), pots getting stuck at full output (!!!), etc. Not to mention it takes some skillful soldering to get the resistors mounted to the BS version, which I find is getting challenging as my eyes get older. I'm dumping these faster than a mobster dumps rug-wrapped bodies into the river. :eek:

Hi David...Thanks for the report...especially on the X-Worssee units !!! The price is very good...looks solid built !
I just wish I did not have to wait on the shipping from Russia !! I am an Impatient Bastard !!
.
I will try to parallel wire the LSP H2S unit and check out the output ~ f( 0-5 VDC) modulation. A while back, I purchased a nice Lazereer Dummy Load ... which will go up to 10A !!! I will let ya know....but...if I see ANYTHING funny on my scope....I will deep six the LSP and order the X-Worssee 5A !!!
.
As to my opinion of the P3...well...I too experienced several..." Anomalies ".... meaning LD's going poof....Now that you have opened this " Pandora's Box ".....I did not want to say this...BUT....most P3's worked fine....a few did not....back when a Oclarro 63193 was 100 bucks....this was a sad event indeed !!
.
One must admit that the P3 was...I believe....the first driver entering the reasonable price range for us....but alas...I do not really trust them.....and the ones that failed were the "BS" type.
.
SO...I will experiment....and report back !! Anyone else with more experience with parallel wiring the LSP H2S ??????? Jordy...have you done this arrangement with the H2S ???? David...do you see any reason I should not try a parallel wiring arrangement using the H2S ?????
.
I hate to abandon this H2S driver....but...I will hate even more to let the "Magic Smoke" outta the 07E !!!

Work has finally resumed on this off the wall project !!!!

On your first post you said you wanted to put the drivers in series. I want to point out current in series stays the same and voltage adds. Current adds in paralell and voltage divides between the branches. Etotal= I1*R1+I2*R2. For series. Rearrange
Itotal=E1/R1+E2/R2. Parallel is more complex but the point is as stated. Always think series voltage add paralell current adds. Easy to remember without the math.

If I'm speaking down to you I'm sorry it just seemed you were thinking backwards.

I've seen the circuit for the p3 and its solid. I also had weird things happen but it's not the design. It's usually power or a bad batch of boards. The circuit is super sensitive which is why it is so good. If the board is off it messes with the function.
I still prefer them and use them whenever possible.

Mr.K...First let me say...thank you...you are surly not talking down to me regarding electronics !! Quite the contrary !! I have a rudimentary grasp on Optics...but... concerning Electronics...Well..." I am a Lost Ball in Tall Weeds " !! Oh Yea !!
.
I think my confusion is based upon discussions in past threads concerning using one (1) driver... to drive two (2) diodes ! In further recollection...I seem to remember pro's/con's concerning using a Parallel vs. Series wiring arrangement.
.
So...this is something completely different !! OK...Now I understand...Only a parallel arrangement can provide more current ! Each of the two (2) driver units on the H2S unit are rated @ 2.2A max. The NUBM07E can take up to 5A ( With some degradation to MTTF of course ).
.
SOooo...Do you predict any danger to the diode by having each driver adjusted to the max current setting of 2.2A...and having the
each driver Anode/Cathode output going to a single NUBM07E LD ???.
.
OR...Should I stop screwing around...and get a X-Worssee 5A and call it a day ????
.
Thank you for your time to help !!! I have a scope...but...have very limited knowledge on how to use the unit !!! Gotta learn that also....So much learning to do...so little time !!
.
Thank you, Bob

Get the right device for the job. There are a million problems possible with using two devices in paralell. You have to take on faith they will like each other long term! They can for complex reasons decide not to share the load even. Running devices even single at top rating is asking for short term failure. Hell you'd be better off using three running at 1.4A. No get the single device rated for the load plus a good 30% or more headroom. Or use two drivers on two diodes and a pbs cube on diodes with less power and better specs.

Ps names Marc not Bob. Interestingly I know sooooo many people in electronics named bob. Kind of the engineer name.

Hahaha...Who names their kid " Bob " anymore !!! NOBODY !! We are an DoDo species !!!
.
Anyway...THANK YOU...for saving my poor...helpless... NUBM07E LD a dark fate !! Both " Clickamouse " and I are working on Lumia Projectors... Both wanting to drive the NUBM07E to it's full potential !!
.
We will take heed and purchase a higher current driver...most likely the 5A X-Worssee units !!
.
Thanx again for your patients and assistance !!
.
Bob
.
Note: Clickamouse and I have been talking...it is high time we do a LEM...And...Cleveland would be a perfect central location !! Marc...what do you think ??

CD,

I too have used several drivers in parallel for increased current. The only negative is that a fault in any will screw things up. It is a little like flying the old multi engine Aztec. Two motors, each unable to provide enough power to keep flying and so, when either fails, the other will only be able to bring you to the crash site.:o

Get a single driver that will do the job, if you can.

I have a tangential question. I would like to pass two, very powerful beams through a single diffraction grating that slowly rotates, continuously. I have the gratings, but I need the rotating optical mounts. I want to set this up for Christmas and need to do this quickly. Any suggestions?

Mr.P...What is a " Rotating Optical mount " ??
.
Is the grating a thin plastic film ? Just cut the grating in a circle...put a hole thru the center...If the DG is thin...just mount to a clear plastic disc....and then mount that to your rotator motor.
.
I have a motor...which I received from Clickamouse.... which was used in a Lumia set up. I will check the RPM. I could drop it in the mail...2day...PM me with details...I am sure we can beat the deadline !!!
.
SOoooo...MMMmmmm ??? " How much juice are ya putt'in thru the grating.. " ????? 5W....10 W...15W ??????? That'll lite up the stage !!!
.
HO, Ho, ho
CDBEAM

A rotating optical mount would simply support the glass grating (2"x3") and allow a slow motor to rotate it in the plane it is mounted against. My back up is:

http://www.ebay.com/itm/Newport-RSA-...EAAOSwp5JWVLqg

With a 12V gear motor, belt driving the manual rotation knob.

Power? I'll PM you.

Well...one could do this....BUT....Seems a bit OTT !! See attached the motor I will send you...if you like.....12 VDC @ 5RPM....that might be slow enough for your application.....You are fighting a deadline......I say...just epoxy the 2" x 3" grating to the shaft mount adaptor...and give it a whirl !!!
,
Bob

Belt drive over a hollow cylinder. Grating in hollow

That is the plan. I just purchased a used rotating optical mount (not the one shown- bigger, cheaper) and will drive the OD with a belt. Three great minds...

HAHAHA...Two (2) great minds...One (1) great mind wannabe ====> CDBEAM !!....however...never a shortage of wise ass comments...or ... insightful and stinging comments/cartoons.
.
This place needs more humor !! AND...need some excitement !!! We need a new LD !!! We need some new beam combining methods...
Who came up with these stink'in " Laws of Optics " anyway ????
.
Hey Spec....you still out in the Ether ??? How'bout a new section....just for " Laser Lumia/Laser Abstract "....Clickamouse suggested this to me the other day.....SO...seemed like a fine time to request it !!!!!!!!!!!!!!!!!!!!
.
I predict you will see some novel things presented regarding Laser Lumia/Abstract in 2017 !!!!
.
Anyway....I will descend from " Speakers Corner "....but..." I'll be Back "".

Bob, if you find you're still in need of a driver shoot me an email, I think I can help you out.

THANX Adam !!!...I will get with you !!!
.
X-Laser = " Les Bouillens le Photoniques "
.
I have some crazy ideas to vault "Laser Lumia" to a modulated and controlled venue....and I am full tilt on bringing these ideas to life. I am not sure the concept will work....but....the fine folks at Foxtone and Sweetwater Music Synthesizer's say they will !! We will see !!
.
My theory is that if one links Lumia display...to music content....in the proper way.....then a synergy of entertainment will occur....yes...just refer to " Beam Axiom #2 " hahahaha !!!
.
See... http://www.photonlexicon.com/forums/...to-Laser-Lumia .... for the original rant on this Lumia project !!

.

I have seen a lumia display mixed with a laser show. The lumia was so diffuse and large that it mixed well with the much more intense laser graphics. Still, it is important not to loose "the power of black" that totally dark interludes, in a show, serve to spice up the brilliant lasers.

SOooo...We need a " Dark Lumia "...or....a White Lumia....set at low intensity. Alas....I believe our " Distortion Disc " also diffract the combined RGB...so...no White Lumia....YET !!!
.
A while back Eric....YOU made a suggestion which may solve that conundrum !! I am working on that !...however unlikely a solution will be found by me.....there may be a way to do it....and there may be a work around to Prentice's rule !!
.
Bob
.
Wait...don't tell me...it has already been done...great...I would like to see what it looks like !!!

Use incandescent light for white

Well....As long as we get the nebulous, typical Laser Lumia pattern....sure....Incandescent......But...I believe the initial coherency of the beam as it propagates thru the Lumia disc sets up interference patterns....which in turn deliver the sharp, yet nebulous typical Laser Lumia we are used to producing !!.
.
Look....I only know enough about this to be considered a hack...no more !! I am sure there are many members who have forgotten more than I know...SO.....please...let them speak up !!
.
SOooo...Let's pump a Supercontinuum Laser beam thru the wheel....Yea...I am sure there's an article in " Laser Focus World " about this very topic !! HAHAHAHAHAHA....." IT COULD WORK "...so sez Dr. Frank N. Stein !!!

If you can focus the light you can make a beam. If you can do that you can make lumia. Look around you and you will see white lumia all the time. It's just not as sharp edged. Shine a flashlight through cellophane that is crinkled and you will see white lumia. It's not very exciting nor is it very luminous.
If you used a continuum laser the luma would still spread the colors out. There will always be refraction. Same even with a flashlight just not as pronounced. You could use an old super 8 movie projector and an aperture. Sort of gobo it. Wonder if that would work. Lens /lumia near focus/ lens out. Sort of a messed up spatial filter. No need to focus as tight though.

What would be cool is a light gate so that only light above certain threshold came through. Would make excellent contrast enhancement glasses for laser shows. I've tried sunglasses but it dims the image too. This would be a fast gate that once it see light above a threshold comes full on and then clamps down but only lets the brighter light through not the whole field of view. Infinite contrast. Could not think of a way to do that. You can gate the whole view with lcd but not just the bright spots.

A neat light source is the new retro-fit HID lights for cars, not the even newer LED retrofits. These 12V modules come with a bulb, driver and a few bits and pieces. They are low cost, EXTREEMLY intense, painful to look toward intense, and robust.

This Retro-Fit HID sounds like a more compact, less heat generation option. Hmmmm...Wonder what flows out of the Lumia disc's when this is feed in ???....Now...to mix Laser vector graphics...with a white Lumia field.....That is something I have NOT seen B4...but then...I do not get out much !! HAHAHA !!
.
Robust and low cost...perfect !!!
.
SOooo many projects...so little time !!!

Check this out as a light source. Add Lumia and your done.

Mr.P........Have you seen these ultra bright HD lamps ??? Got any specific recommendations ?? With the auto aftermarket....should be a good price vis - Economies of Scale....And....Autozone is on the corner...if it does not work out...back she goes !!! Got a few days off....will do some shopping !!!
.
But...I wonder....will we get a refraction effect....due the fact that...we start with Blue...and convert via a Phosphor filter to white ??? ...MMMMM ????
.
.

AND....As presented by Dave !!!! Just look at this !! https://www.youtube.com/watch?v=b-erF4zC07M
I think it is inspired !!!
.

I wonder what 405nm....propagated thru the Lumia media....will look like.....on a GID beam target....OOooooo....AAhhhhh....Put'in on my " Timothy O'Leary " hat !!!
Nebulous clouds...in Slow Mo.....No Stems...No Seeds HAHAHAHAHA ! JK !!!....MMmmmmm...." Optical Lumia Reverb "....yea....everything must have a name....and a " Donk " on it !!!!.
.
While all this may seem -Off THread...not so...for this NUBM07E LD is destine for my " Solar Prominence lll " Lumia project !!!
.
Anyway....Merry Christmas...to all you...out there in the Ether !!

I bought a pair a few months back for another purpose. I'll find the make and model. They worked well. There is no filter. There are HID lamps. The output is directly from the tiny discharge in the arc lamp.

Have you never experience the odd issues with beam suppression? Where it flickers or still randomly decide to glow?
I had always used them and when not needing suppression I still do.

SOooo... I remember now...The HID...High Intensity Discharge...is the condensed/refined point light source version of the Carbon Arc Lamp....and being a point source can achieve relatively good (low) divergence !!!...and generated a full visible spectrum light source....IIRC
.
CDBEAM

Yesterday..... Clickamouse pointed out to me....
" Full Spectrum " light...is just that...FULL SPECTRUM....All the colours !!
.
SOooo....when we prop white light thru any Lumia distortion media.....we will still experience the Prismatic/Diffraction effect...
.
Well...He has experimented with this white light source....as he is my Lumia Mentor...I expect this is indeed the case !!
Any white light source will likely suffer from this effect...or..."LED" effect...
.
" Lumenatic Emission Dysfunction"...yea....another brilliant nomenclature...no extra charge...Haha
.
'BUT...Take solace....we have a plan on
how to work-around this pesky Law of Optics.

Didn;t someone on facebook just post a holiday setup that used white nebulas that ran for like a month or more straight on buildings? i'll look for the postAttachment 51445

Of course you will. All whits light is broad spectrum. If the white is composed of a smooth distribution of component colors like an incandescent source such as the sun or a hot filament then the prismatic effect will be continuous, but if the "white" is composed of discrete components like a RGB laser beam or a plasma discharge in a HID lamp, then the prismatic effect will be discontinuous.

Refraction caustics will have chromatic aberration. Reflection ones won't. ;)

OK... Thanx Dan/Mr.P......Reflective media will not suffer from chromatic aberration... IIRC...per MG...the original stage lumia was incandescent reflected off krinkled cellophane material...so...therefore...no chromatic aberration.
.
But...if we use HID or incandescent....we will loose the interference patterns which I am accustomed to seeing with Laser Lumia.
Also...with a refraction Lumia generation method....the Chromatic aberration will be present...be they continuous or discontinuous.
.
PB...looking at the referenced pic above....Yes...looks white....looks kinda like Lumia...but...not what I am used to with Laser Lumia...Not sharply focused, not nebular, no interference patterns....so....I assume made with HID....via a reflective method.
.
Like I said....I want it all !!! Sharp focus, Nebular, Interference patterns and FULL SPECTRUM WHITE !!! Is that too much to ask !!!! ??? I fear the pesky Laws of Optics will rule the day !!!
.
The " Solar Prominence lll " Lumia project will employ ...Co-axial RGB propagation....which I predict will deliver some white areas...errr....maybe....but nothing fully white....sigh....stink'in Refraction caustics !!! Where is a White Laser beam....when ya need one ????

CDBEAM

Most, if not all, popular diode drivers can be modified to drive upto 5A.
Just find out the Imax of the used fet, and if there is enough supply voltage to open the gate at the desired current.
Reduce supply voltage to minimize dissipation yet enough to open the gate. Use sufficient heatsinking.
Replace the sense resistor with a lower value, or place an identical one in parallel.

Bart...I must admit...at this stage in my training of electronics....ya know...."For 8 year olds and under"....although I am sure your mods will work....I will stick with the " Outta the Box" units !!...until such time....after some training with Draco....I might attempt such a modification !!
