    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    It is probably gonna be hard to find a driver that can push enough amps and if you do it will most likely be pretty expensive. I have built this system using an arduino (http://www.arduino.cc/) to control it so I am using the Meanwell LDD drivers...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    I was out of town last week and didn't have time to mess with this project. That code still gives me strange results. I went ahead and pulled a Meanwell LDD driver out of my terrarium light and it works for me with no problems. The difference in light output is small when stepping down to 1A...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    Sorry if I was unclear, I was simply saying I couldn't get the light to turn off for a starting point. I want to use analogWrite to be able to dim the lights using the analogWrite values of 0-255 for pwm dimming. I have done this with 3W LEDs and different dimmable drivers. digitalWrite HIGH and...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    I just tried it with a different led and driver using the same code from my last post and got the same results.

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    Here is my sketch, simply trying to turn the LED off with setting analogWrite to 0. int ledPin = 9; // LED connected to digital pin 9 void setup() { pinMode(ledPin, OUTPUT); // sets the pin as output } void loop() { analogWrite(ledPin, 0); // analogRead values go from 0 to 1023...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    Well if it is not the frequency or the voltage I am not sure what the problem is. I just tried it on an arduino uno rev3 and got the same results. When I connect the pwm pin I notice a very slight decrease in light output and the light seems to flicker extremely fast but changing the pwm value...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    I am using an arduino mega with pin 9 for pwm. I'm not sure what the pwm frequency is, it is just what it is automatically set to. Do I need to change the frequency to 200hz? Also how do I set up the pwm to be on 5v instead of 3.3v? Thanks for the help

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    Guod, I hooked up an RCD-48 to an LED and cannot seem to get it to dim with the arduino. I have the power supply hooked up to pin 1 for vin and pin 2 to the ground, pin 4 to an arduino pwm pin, pin 6 and 7 to the LED, and connected the arduino ground to the ground on the power supply. When the...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    Thanks for the help. For a power supply I was thinking of going with the Meanwell se350 (http://www.mouser.com/ProductDetail/Mean-Well/SE-350-48/?qs=sGAEpiMZZMsPs3th5F8koBXG/88ctzcMhAVYYOTnmak=) as I have used it before, it is reliable and not that expensive. It goes up to 7.3A so I could only...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    I couldn't find a good choice on those Meanwell drivers that wasn't upwards of $40 each. I think I will go with the 1.2A rcd driver suggested by guod (http://www.mouser.com/ProductDetail/RECOM-Lighting/RCD-48-120-M/?qs=sGAEpiMZZMt5PRBMPTWcafkZyLbOcVwI1Ud2vaoFQZE%3d). I am slightly confused with...

    DiY LED Grow Lights with CREE CXA3070 COBs and CPU Coolers

    Can anyone suggest a good driver for these CXA3700's that can be controlled with a 5v pwm from an arduino? I have used the Meanwell LDD line but cannot find one that is similar to recommended drivers power. They have a 1.5A one, the LDD 1500L...

    Arduino controlled driver for CXA3700?

    I am planning on building a LED light based on this thread (https://www.rollitup.org/t/diy-led-grow-lights-with-cree-cxa3070-cobs-and-cpu-coolers.805681/). I have already started working on a arduino based watering system and figured I should hook the LED light up to the arduino. I am trying to...

    bestvaluevacs.com review

    I recently purchased the 3 gallon kit to vacuum purge my BHO. The kit works as advertised and can attain a 99% vacuum. I managed to break a solid brass connector to the ball valve (not a cheap piece just a dumb move on my part) and they sent me an entire replacement lid with a new hose for free...

    Need hydro help, tangled roots!!!

    What do you mean I wont get root rot unless I over water? Its hydro so those roots will just be sitting in a tub of water with all the roots from the two females.

    Need hydro help, tangled roots!!!

    So I should just cut the branches and try to pluck any balls on the main stem while trying to leave the fan leaves? Will I have to routinely check for new balls and pluck them off quickly? I am going out of town for 7 days this Saturday, will I need someone to come and check and cut out any...

    Need hydro help, tangled roots!!!

    I am growing in a hydro system with three plants in a 15 gallon bin. I have used this system many times with great success however this is the first time I have got a male. One of three of the plants is a male and I want to remove it but the roots are so tangled I don't know if I can ever...

    Bud Drying Clothes Hamper?

    I have always hung my buds up to dry them but just recently went to a local dispensary and was looking at their method. They use what looks like round collapsible clothes hampers. They are basically a standard collapsible laundry hamper that has about 7 levels in it instead of one bottom. On...

    A Comprehensive Review of the Aerogarden

    I have had some trouble with this system with having my plants be males. I have been using the aerogarden nutrients and was wondering where you purchased you nutrients and how much to use each time.
