Fanleaf's Huge 42 COB Array Build Plus Other Builds

If you've got any ideas on what type of heatsink is best (and dare I say cheapest) to go with your 6 cob design, I'd like to know.
Im guessing two long fin types alla Rapid Led kits, stuck side on.

Don't even look at it!

haha that's funny....


I looked up your drivers. Yep, they will work with 1 driver per cob chip. You won't be series or parallel lol. All single 1 cob per driver with those.

Cheapest and best never go together.
Best....IMO Arctic Silver 5
Great and good cost= Arctic MX-4
 
Because there's the Meanwell smart dimmer you can use. It's USB programmable.

Aviation plugs rock. They are so solid!
The switching worked like a charm. I posted a vid on page 60. Thanks so much for all the help.
Ordered 6 meat chips. Vero 18. The 29' won't be in until April. I'll send you some after I get this flower test done.
If I don't like the Vero meatchips I'll use the Citi 90cri 3000.

Sweet man. I thought it should work. Always tough when your just picturing it in your head ya know? I'll go back to 60 and check it out. I'd love to try a few of them "meat chips"...That name rocks!

Ah ok i thought you were gonna show me heatsinks?
Or you did but I've missed it.
Every link so far seem to be for paste.

Oh, my bad. I thought you said thermal paste....:loopy:
Depends. You can go active sinks cheaper but need to drive the fans. Or passive costs more. For you I would recommend active with fans. Your Arduino can drive those soooo easy.

THIS IS A CONSTANT CURRENT MEANWELL DRIVER

Your driver shows the added total of the cobs in the series right?

And how do cobs rate a maximum MAH when the voltage is not effected in the rating. Like why don't they say

"Cree CXB3590 5v-45V after all you can achieve that through dimming?

Im still lost on this part. I think the dimming aspect throws my understanding a little.

But constant current seems to be the best way to go for protecting the cobs and quality of light?
 
It's good to see people designing systems with computer controlled drivers. :cheesygrinsmiley: :bravo:

I was considering a Pi for awhile, but controllable drivers are still pretty spendy and I'm working on getting the cost down for my first rig. I once had a blurple panel that could be controlled in intensity and time in three spectrums - really cool! You could mimic dawn and dusk, work with GLR - all sorts of fun stuff. Unfortunately the drivers were crap and it didn't last a year. :straightface:
