Now ...This is ..art !
P2286150.JPG...
( excess solder paste made bridges ..had to take away the leds ,so to clean the contacts ...In fact I was bored to clean-off the excess .Kinda bet with myshelf if it is going to bridge ..." Yeah ,I f@ckin' knew it ...


Leds taken away really fast ,with alternate -partial pcb hot plating ..
Phone rang ....Empty pcb was left besides ceramic oven plate ......
Dunno how on Earth ,moved to center of (still burnin' hot ) ceramic "stove plate " ...
There's where I found it ,15 ' later ....Looking like that ....Cool .... )

Leds ,resoldered to another pcb ,which I haven't left enough to solder good ...
Placed it ,on heatsink ,just to find out that at 200 mA two whites where going totally off ,and one red was flickering like an old lamp ,outside a filthy ..Bar del Eau ...
..
Take out the pcb ...bending it a bit ....
Resolder the leds ...
Test them .Great ...
On to the free heatsink rivet hole prepared space ....
Tomorrow will clean heatsink ...Take another pcb (I've made plenty !!! ) and solder the remaining leds ....

While the new ones are arriving ....
It's rather great to have a job..
Even for some days only, of the whole week ..
Way better ,from nothing at all ....)


The internals ,today ....

Stardustsailor and Guod,

This is soooooo cooool! You rock the DIY world big time. Making me want to try it! Thinking about a ring shape to go above a mainlined scrog circle.

Just a quick question. Light travels in waves and so they can cancel each other out at certain distances. Is this an issue with these emitters?

BTW - I have a Kessil H350 Magenta. I am thinking about getting another. I would have gotten the Tuna Blue (adjusts from 10,000K to 6,500K) but your info about blues makes me just want to get another Magenta.

Cheers,
Mo

Light waves add and subtract. That is why some patterns look bad on TV. Scientists use the interference as a tool to tune out different wave lengths by shining light through microscopically slotted metal screens. It is cool stuff but it can couse havoc on lighting patterns.

Sound can do the same thing (ie noise cancelling ear phones). When two identical waves are 180 degrees out of phase they cancel each other. I wonder if there is a spacing pattern that would be optimal to avoid cancelled light transmission?

Here is a link to a cool demonstration: http://www4.ncsu.edu/unity/lockers/users/f/felder/public/kenny/papers/quantum.html


Cheers,
Mo

So ..they cancel each other ..
What ? light just " disappers " ?
Or start going backwards ?
Or change color ?
Or become heat ?

Sunlight as it passes through atmosphere and it's " abnormalities "
( random placed particles-diffuse /absorb ....random placed water vapor molecules ,same diffuse and absorb ....
Clouds .,ect ....
So same sunlight ,differs all the time ....

Now ,as it reflects to various objects and landscape features ,it gets massively absorbed ,creating a colourfull world ...

Light that gets reflected ,probably cancels sunlight ,or part of it ..

According to your quote ..


(Although "coming from nowhere ...
You could 've left your purple /magenta or whateva space-disco colored sten-ssils out on the front door ,
while entering into a " White-red " DIY house ,dear brother ..
Out of politeness and only ...)


Anyway ...

Right ?

Because sunlight comes from above ,breaks into pieces ,gets reflected so to cancel itshelf (the incoming sunlight
)...??????

I need your "favourite strain " list ASAP ....

Pure Sativa man! Colombian Gold, Panama Roja, Thai, Malawi, Mulanje, Mozambique... Heart racing paranoia!

Ever wondered why some patterns on buildings look like they are moving and you just cant seem to focus on them? The front of the old Stardust hotel in Vegas was one building in particular that looked like it was moving in the sun light. That is caused by the reflected light pattern causing interference patterns. The pattern in the building is equal to a particular wavelength of light.

Anyway ....
Even if something like that is going on ,at mama-nature ....

Still probably 99.99999% sure ,plants " know " about it ...
Know how to deal with it ...
Personally ,I'm 100% positive ,about it ...

Millions ,trillions of Chloroplasts ?
Some " tuned " like 'that' for 'that' ...
Others ,otherwise ...

Plenty of photo acceptor's (pigments ,photosynthetic ,accesory ,photomorphogenic ,phototropic,circadian and other ) molecules ..

Same ChA molecules can operate differently ,on different parts of plant,under different situations ..
And so on ....

Plants are generally ...How I should put it ..? .."Versatile " ....
Easy to adapt (change ) .....


As a life form ,that can not move ..
Not being able to physically act ( at higher animal time and movement terms )..

For sure they differ in other ways ,so to survive ....
They adapt in no-time !
To almost everything !


Some 'things' do promote their growth ...
"Make them thrive " ...
Make them happy and 'fullfiling' their lives ....
First of all is light ...
Rich ,nutritional energy packets ....
Photons of all kinds ....For all "needs " ...

Of course "common bi-chromatic " ....smokeeeeeee on the water and fire in the sky " .....colored combos .........
Do not fall in the category of "nutritional light " ....

"Accessory " ,yes ....
" circadian controlling " ,can be ...
"Stressful for nutrient enhancement " ,can be ....
..
"Full " ...As plants ,mean it (and show to us stupid humans ) ,ain't ...

What do you think about using an aluminum grid for the led mount/heat sink?

I think the ultimate will be when we can put small LED screens over every leaf and pump the photons in - boom! No shaded leaves, 100% photosynthesis tuned energy input :)

You guys are making this a reality! Next stop, the future :0

with light it will be hard but it´s possible (laser)

here is a more understandable way with acouctic waves
http://en.wikipedia.org/wiki/Noise-cancelling_headphones


OH,Guod dear ...Now ,I'm going to ...

Light Amplification by stimulated emis.....blah-blah--....
Amplification.."Add.."
Not cancelation


Bang to the mirror ,bang to the other mirror ....New comers coming in all the time from the source ...
All together at one point escaping the semi mirror ....As coherent light ...Way powerful ...
(I used to own one CO2 40 Watts ..Turning stones into lava into secs ...Got rid of it ....Way dangerous hobby ...
Once had made one of 30 mW ,that had Cherry jelly as g-med.... )

".......

Sailor ,went down to the "cultivation sector " ..
At 7th deck below bridge ...
..
There was all the plants providing fresh air to the whole ship ...
And it's crew ,of course ...

Also,'waste ' from crew ,(common : shit,crap ) was biologically fermented and supplied to plants ,as a full -nutrient organic fertiliser ..
Along with their fallen leaves/ dead stems ,and ship's pet's/animal's waste ...

Oh...the most important one ...
" Cultivation sector" with it's 500 hectares grow area and 3000 cultivated species ,was the main ship's food,oil,fiber,polymers,detergents ,wax,grease ,ect and of course medical botanical drug supplier ..

Plants where growing ,using the old -fashioned way of 90% efficiency Leds ...
OStar XXL ....

Good and trusty light source ...
But the optical fiber matrix was something else ...
Plants and -thinner than hair -glass fibers ,mixed ...Blended together ,in a weird luminous green creature ....
Way impressive ....
Plants grow so fast ,that one can actually see them moving as they grow bigger ,every minute ! ...
Oh ....

Sailor ,has to go ,check the water pumps ....
There's a new species ,that seems to have some sort of " intelligence " ....
Opening ,with its branches the water pumps to get more water to all of the plants ....
We gotta smoke 'em ,out ....

Hey ....
A bigger ,for sure ,more "curvy -smooth design ,with fake-cheapest screws and fan guards ..
But still a moon-shuttle also ......
Who has noticed these "mushrooms " ?
No protective lenses or glass/screen ...
Bare leds and four (silicone most probably) mushrooms ...
helios 1.jpg
Mine are better ...
At least from ,from those transparent door-stoppers ...
Ergal screws and PET ink cups ....
Replaceable ,easy to remove ,still serving the same purpose ... ...
.....
Funny ....

for sure I was expecting more from the swedish ,regarding overall design ..
It seems really more of a "research " light ..
(Not tough ... Build material (except ..most of leds ..) ,seems worse than plenty of Asian lights ..)
No I'm not beeing shitty ...I'm saying what I'm seeing ...

Not a work-horse for sure ...
I bet ,that metal case is made from ordinary iron sheet ...
Not ally ,not inox ...
Maybe is not even galvanised plated/ protected ...


(Cutting production cost down ?
Just to have plenty of high-quality leds ..
And a fancy-covered pcb ....?
I wonder about what the "autopsy " will show ,I someone "guts" this thing .....
What's inside there ? ...I wonder ....
Hmmm...

Thanx for the correction ..(Basically is my ADD ... )

As for the fictional story ..
Whatever ...

..
Now ..
Light is finished !!
Replaced also damaged mc pcb ...

And while I'm on the White +red Spectrum for my leds ...

P2286158.JPG
.........
I like the R_G_B coloring on my mcpcbs !!!
P2286155.jpgP2286157.JPG........


Power at plug-( PSU-drivers-fans-leds ) :

At lowest setting (~200 mA ) : 25 Watts..... P2286165.JPG
At highest setting (~710 mA ) : 95 Watts ....

P2286166.jpg....

I just need 2 or maybe three of those babies ....

Oh ...Those Oslons ....

Do not let the tiny size fool you ...

They seem so fragile ,those tiny ones ....

Well ..

They aren't ...

Pure german quality ...

A set of them ( 4 x reds & 8 x ww ) was soldered again and again for 4-5 times !!!

3 or four have dropped from my hand ...
Actually stepped on one of them !!!

Works fine !!!
Lens is undamaged ...( What kind of hard silicon is that ? Soft but extremely abrassion resistant !!!! )
Body is ceramic ....

Actually ..Another one had an .."mishappen " at last mcpcb ...

Rivet tool slipped,while cutting the rivet and .....Crushed on a led !!!

P2286167.JPG...
Well ...Who cares ..

Still works as new !!!

Awesome robustness !!!
Amazing ! ....

Love that graph

Your 'fictional' story is not so fictional. Many think "if I can just get off this crazy fucking planet..".

Sadly, the matrix includes outer space. Lots of very large city size craft there with millions of missing worker bees.

Should the end of earth occur during your lifetime, whatever you do, don't get on any fucking space craft. Die with mother earth

Pet ....You're missing one "hot_point " .....

We (all of us ) are already aboard on a "craft " ...

Way bigger than city-sized ...

Huge ball -sized ...

Still ,with million working bees ...

Missing or not ..


As for any "outer space crafts" coming to Earth .......
Once read a story ,written actually somewhere here at this land ,I live ...
Really weird story ....Ending like ...

21:2And I saw the holy city, new Jerusalem, coming down out of heaven of God, made ready as a bride adorned for her husband.

.......
21:10And he carried me away in the Spirit to a mountain great and high, and showed me the holy city Jerusalem, coming down out of heaven from God,
21:11having the glory of God: her light was like unto a stone most precious, as it were a jasper stone, clear as crystal:
21:12having a wall great and high; having twelve gates, and at the gates twelve angels; and names written thereon, which are the names of the twelve tribes of the children of Israel:
21:13on the east were three gates; and on the north three gates; and on the south three gates; and on the west three gates.
21:14And the wall of the city had twelve foundations, and on them twelve names of the twelve apostles of the Lamb.
21:15And he that spake with me had for a measure a golden reed to measure the city, and the gates thereof, and the wall thereof.
21:16And the city lieth foursquare, and the length thereof is as great as the breadth: and he measured the city with the reed, twelve thousand furlongs: the length and the breadth and the height thereof are equal.
21:17And he measured the wall thereof, a hundred and forty and four cubits, according to the measure of a man, that is, of an angel.
21:18And the building of the wall thereof was jasper: and the city was pure gold, like unto pure glass.
21:19The foundations of the wall of the city were adorned with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;
21:20the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; the twelfth, amethyst.
21:21And the twelve gates were twelve pearls; each one of the several gates was of one pearl: and the street of the city was pure gold, as it were transparent glass.
21:22And I saw no temple therein: for the Lord God the Almighty, and the Lamb, are the temple thereof.
21:23And the city hath no need of the sun, neither of the moon, to shine upon it: for the glory of God did lighten it, and the lamp thereof is the Lamb.
21:24And the nations shall walk amidst the light thereof: and the kings of the earth bring their glory into it.
21:25And the gates thereof shall in no wise be shut by day (for there shall be no night there):
21:26and they shall bring the glory and the honor of the nations into it:
21:27and there shall in no wise enter into it anything unclean, or he that maketh an abomination and a lie: but only they that are written in the Lamb's book of life.



Anyway ....
I'm not planning on getting aboard on any ship./..
....Except my own...
