I was always high when I went to electronics school...
I cant remember anything or didnt learn when it comes to writing code.
Hopefully I can learn...

I am considering an Audrino, and see there are several models to choose from.
Based on price is the the Zero is most expensive.
Which one is the best to buy?

high Sativied,
Always. :eyesmoke:

so do you really need the Osram SSL 120?
No, don't "really need".

It looks like a great addition to the cob's... but is it effective by the distance to the plants?
Sure, it's not like the light dissappears, just spreads out, as it should.

i'm also interested in the Androino setup...
that makes it perfect to me...
Do you think that the platform is stable enough to run 360day's without issues?
Absolutely. Whether that is the case for the chinese clone I use I will have to see, but I got a spare and can easily replace it. By itself arduino platform is suitable for long term critical applications but does depend on how you set things up.

@Sativied
Also Is there some cheat sheets on Audrino and basic setups?

The most commonnly used are the Uno and the Mega. The main difference in practice is that the mega has more pins (ports to use for input or outputs) and more memory. Uno has only 32kb for code, mega 256k. I dropped a few links in this or another thread (search my username for "instructables") to cheap chinese starter kits that are imo the best way to get started with arduino. $20-30 and you get the arduino and a whole bunch of sensors and wires, resistors and other typical items. Depending on how much you want to attach to it (as in how many pins you need) an arduino Nano can work great for a finshed project due to it's small size and price, as little as $5-6.

That would do for dimming for a few drivers, temp and humidity sensor, timer and relay.

In any case, get the so called prototype shield for the uno (fits mega too).

Yeah, more than you will ever need. For example:
http://www.instructables.com/id/Arduino-Projects/
https://learn.adafruit.com/category/learn-arduino
https://www.arduino.cc/en/Tutorial/HomePage
And many many more. There are libraries and sample code for pretty much all sensors and other outputs and inputs. Lego for adults. The coding is as 'basic' as coding gets.

Thanks for the reply!
Ill look into all this and hopefully get some automation and a screen to display sensor readings

No, that depends on how you want to drive them, how many, and how you connect them, budget, desired efficiency, etc. Best driver is the one that suits such factors best and those are more relevant than them being osrams ssl. In practice that usually means matching current, voltage and thus wattage to a constant current meanwell or other driver.

Nice job and a good looking light. A little ceiling fan above the rig set on low like Growmau uses to create a little air flow, and the thermal efficiency of the pin heatsinks will greatly increase and yer COB junction temps will decrease. Yer gonna have an oscillating fan in the grow anyway for air circulation and plant health.
I have a fan up you just can't see it in the picture. I can leave my hands on the heat sink anywhere and not get burned. Same with the lenses. And that's with the light on full blast lol.

Temporary setup for testing (the side by side by side thread)

16 4000k DB cxb3590s ran at 50W each (61% Efficiency) 800 Cob watts in a 4x4 config.

The last photo was my original 5x5 setup running at 400W next to a 1000W DE HPS. Can you tell which one was brighter? Lol I like this thread.
Smart. More people should utilize square baking sheets for frames. Hole saw your cob space and boom. Done.

high,
well got it... if someone looking for it...
Meanwell LPC 20-700
with this driver you can use 1 or 2 x Osram SSL 120 Onion...
it's good for cloning etc. because of the distance to the plant but if you are more than 50cm away from the plant it's waste of power...
but looks good :-)
What do you mean on the driver?
it's fine... good choice... was misinterpreting the numbers on the driver...
nice design... love the passive cooling.

Onion link? That driver can can drive 11 or 12 x osram ssl 120 at 700ma in series. 1 uses only 2.3 volt x 700ma = 1.6watt each.

I agree 700ma is in most cases the way to go with these osrams (gets pricey to get same output at 350ma and less efficient at 1000ma) but... that doesn't mean you need a 700ma driver, or a different one than the cobs if there's room on the driver.

I run 4 cobs and 8 osram ssl on a hlg 320 1400ma driver. Cobs at 1400, osrams at 700ma. Using ~315 of the 320w. I know, would be better for the driver on the long run to not max it out but it fitted so nicely and I wanted them to dim with the cobs.
