this looks great! so every channel is controllable through the arduino? have you build in network access?

I was trying to get it all linked up to a arduino but had to take it out. The drivers weren't as compatible as they could have been. Didn't want to waste the drivers..

I have a dimmer on the cobs and 660nm, all tied together on one pot. Cobs dim off and the 660s stay on but very dim. The far red and uva are full 1a no dimmers. If I need to dim those i'll need to switch the ldds drivers out, not a big deal, but i'm hoping the spectrum works well as is. The ldds only dim by pwm..

The next light will go slow..try an integrate the arduino fully, maybe network access but thats a little gimicky. Basically a continual rebuild of my lights. Except I buy less and less parts each time, reusing drivers (although that may change), heatsinks, etc..

Nope...no timers this round. Always on

Looks like space shuttle with those reflectors. Looks great.
I see the left reflector is leaning to left and right reflector to right. Not sure if this was because of how photo was taken or intentionally done for even coverage

Need to check the reflectors again..sometimes i rush and miss a phlange that twists in. Gotta be careful with plastic holders also, more than a little torque will distort the plastic....will be making adjustments..new light...:mrgreen:

One things for sure..this mofo is bright as f@ck for 215w

Awesome job POS. Your silver bullet is chambered and ready to go.

I am waiting on the jumper cables for my storm controller so I don't have to solder directly to the pins, but it's super intuitive and easy just messing around with nothing connected. It is arduino compatible so I do wonder if the converter would work with the typhoon.

...storm and typhoon controllers need a FTDI adapter or similar ...to restore, change or update the firmware... or backup the embebed firmware or code...;)

https://www.sparkfun.com/products/9716

...add more money to total cost of storm or typhoon...

...but seems to me ...yours plans go only on plug and play mode ...actually..

...do you have the FTDI adapter or similar?... ...for gg and pos...

...only for curiosity...

saludos

Have one on the way...figured I might need it to add a relay or whatever else might be available. like you said..at least back up the firmware..

Thanks for all your help salmo..I appreciate all the info you share...:peace:

Thanks gg, haven't tried it on the typhon yet, probably be a little while before I get to it. I usually get burnt out on building things for a little while, then eventually I get itchy to make another..haha. Always some way to improve the lighting it seems. Peeps i'm sure think I'm competing with them...I'm not...just competing with myself..:grin:

Ah, that makes more sense. For some reason I was assuming the COB driver was powering the LDDs. I wasn't planning on running a separate 12v DC power supply, so I don't think the LDDs would help me. I might still add the deep red LEDs, but if I do I'll get a cheapo driver to run them on a separate circuit. Thanks for taking the time to explain!

Hi bigljd!

Maybe off topic a bit late but this Wire Leaded DC Regulator from Recom R-78w for 8,50$ is what you looking for.
http://www.digikey.de/product-search/de?x=24&y=6&lang=de&site=de&KeyWords=Recom+R-78w

Here is a small example:
http://www.digikey.de/videos/en/vp/4007344698001?WT.pn_sku=945-2204- ND&WT.z_part_id=4930588&WT.z_video_source=Part_Detail

For driving a fan with 5V, 9V or12V. The regulator receives its power from the LED driver(6,5-32v). It works good with a single led driver and take only the current it needs, but there is no way to use it with a hlg-120H/185h-Cxxx models.
For me a bit too expensive to drive only one fan because a small 12v driver and a fan controller costs about the same.

So heres the silver bullet finished. My beautiful cover got crooked..lol. May have to bodywork it a little. Its all good though, everythings secure and together.

I'll break down all the parts when I got some time. It'll take a bit to put a nice list of parts together.

Those diffuser in the reflector are raising Tc by 20 to 25 degrees. Diffuser transmission loss 5 to 10% and then another 5% loss due to increased Tc.
Those diffusers do not seem to help much and reduce 15% photons and reduce Cob life due to higher Tc. Seems they are not worth it unless you want to cover the cob. Or may be worth it if you are not careful and have random stuff coming near LES and catching fire.

I think glass Optic lens will also increase Tc depending on its size and distance from LES.

Edit: my bad. I was testing at 2.25a 40vf. The case temp rise would be less for you as you are powering your light at lower current.

Been playing with them a little... Heatsink temp went up with the diffusers on

Will get more into it later. Some good.. Some bad with them

Hello Positivity,
So how are the plants doing? Great looking light and thread so far, but it's been 20 days, do you have any new plant photos dropping soon? Keep up the great work!
Sincerely,
ILovePlants

I'm still searching high and low for those ledil reflectors..where'd you get 'em?

1) Input voltage of these DCDC regulators is 32V max - unsuitable for most of the COBs setups. There are better choices.
2) You can use a DCDC regulator with high voltage drivers, too. Just make sure it can handle at least Vf of one COB and connect it parallel to it (shouldn't be a problem unless you run 72V 3590s).

Yeah Alesh!
You are right, man! Seems okay for Vero18 but not for the bigger ones. My bad!
Unfortunately, there are still too few driwers with 2. fan output(12V/200mA)
Maybe soon if cobs come more widespreaded and cheaper!

mouser had them for a bit, just need to check octopart or some electronic part search engine. They seem to come and go..

Done..recycled heatsink with a few choice leds did well as expected. good light...:-).

Gsc cross had the minty smell with a stinky funk behind it. Prefer the originals sweetness so I'll stick with that. If I didn't have a good gsc already she probably would of been a keeper for a little while
