    DIY: Cree CXA Arduino Thermal Monitoring & Protection.

    Okay, I just browsed over your last thread and took a look at most everything. I really like your 3d drawings, what are you using to do those? The heatsink design looks good, might possibly be better off with multiple smaller fans, maybe a 2x2 array for each LED, and choose fans that have a...

    DIY: Cree CXA Arduino Thermal Monitoring & Protection.

    Exactly, as stated above, logic level FETs can use lower voltages on the gate to get them conducting and turning on, MOST of the time a logic level part will have an "L" in the part number. Like above, the IRF540, as you can see in the datasheet has a gate threshold voltage of +2-+4V DC, now...

    Pineapple Express in Flower for 37 days how much longer (pics)

    I would let it go, bare minimum, 20-25 more days probably. Just keep checking the trichomes, you have a little ways to go, she should def start packing on the weight right about now.

    DIY: Cree CXA Arduino Thermal Monitoring & Protection.

    @stardustsailor , I see where you had some questions regarding your fan drive circuit? Could you let me know what you need some help on and I would be more than happy to help out where I can, now I am a hardware engineer, software is not my strong point, haha. We do a lot of different stage...

    DIY: Cree CXA Arduino Thermal Monitoring & Protection.

    Very nice @stardustsailor , is this your own code? Nice to see some other guys with an engineering back ground, project looks very good so far. I do power management design and board layouts, if you have not done a layout yet, I would definitely be interested in laying one out in my free...

    Cali Conn Chem 91 and THSeeds MKUltra LED - 1st week Flower Journal

    Here's some newer pics of the both, confirmed girls. They are both beginning to stretch some, but I am amazed at the size and girth of the Chem, it is a truly monster plant. I didn't think it was supposed to be so stretchy. Both plants are already putting out a very sour smell.... Hard to...

    Sour Kosher Kush Smoke Report And Picture.

    Their sour kush (headband) is actually their Sour D crossed with their OG Kush. And yeah, I don't know where the hell you are getting those smells and tastes from, both of those plants should be straight sour, fuel, pine, lemon smells because of the terpene makeup of those genetics. What you...

    Yeah I've got those two Reg cc gsc as well, hopefully we'll find a girl in there. Really trying to hop on some OG Raskal gear

    BC Bud Depot GSC

    I would like to see a comparison between bcbd gsc and cali connections "gsc" lol.... I'm sure it's flame though, just not the real deal like he so claimed and then the high times with the cookies family came out and they stated that they had never given out a cut or bean of the real deal gsc

    Yeah I got that freebie too... Good to see someone got a good pheno, I've heard others with less than optimal outcomes.

    Cali Conn Chem 91 and THSeeds MKUltra LED - 1st week Flower Journal

    I think he crossed it with a deadhead og male (sfv og x Chem 91), not really sure how he did it, but I'm pretty sure it was a deadhead male. It seems to have good structure but I guess we'll see in the coming weeks if she's going to be a keeper or not...

    Cali Conn Chem 91 and THSeeds MKUltra LED - 1st week Flower Journal

    They started throwing pistils yesterday, I know exactly what you're talking about but those pods didn't start showing until a week ago. She's a very slow vegger if she's indeed the real deal Chem 91. Maybe it was the 24/0 veg time they were getting.

    Cali Conn Chem 91 and THSeeds MKUltra LED - 1st week Flower Journal

    What's going on everybody? Hope all is well with you all! Just wanted to post up a few pics of one of Cali Connections "Chem '91 SK VA" that is growing in the closet (not the big room), alongside an MK Ultra that was a freebie with the purchase of a pack of their Ultra Sour. The Chem '91 was...

    Chem 91 SK VA and MK Ultra under 320w G8 LED's.... Need Feedback! + REP

    Yeah that is exactly what I was thinking as well @puffenuff (thanks for the +rep much appreciated). Just unhooking one of the clips on the UFO so it hangs more diagonal should get a lot more coverage,especially over towards the Chem.. Or maybe even mounting it, I am amazed at how little heat...

    DiY LED - Cree CXA3070

    How much did you pay for those CXA's and where were you able to get them? It looks like an engineering sample.

    PWM LED dimmer question ( electronics )

    Yah I hear that brother, well if you would like to in the future I would like to help you with coming up with a nice fabricated PCB for driving these kinds of applications, this is what I do at work all day so I'm a little over enthusiastic lol.

    PWM LED dimmer question ( electronics )

    http://www.irf.com/product-info/datasheets/data/irfp4668pbf.pdf IRFP4668 ^ Check out this N CH HEXFET, I have used them multiple times and they are straight beasts. I have a few laying around but they are incredible. Also worth looking into CREE's new silicon carbide Z-fets. They are insane...
