Looking good O2,...I got my bag of parts from Digi Key today.:bounce1: only thing I'm missing are those pesky 6211's, and I think the usps loss my little copper sinks (went to post office, got run around,...will attack harder tomorrow) My cat5 connectors dropped in and the 10pin led header also(connector flush with the board just liked we talked) I have a heat gun coming monday, so I'm close to putting the whole thing together. I have a couple soldering questions I need to ask you. Thanks again,---Rick
Has anyone made an LED driver based on LM3463 6 channel driver IC?

True, True, True. I scored mine during the Black Friday sale last year & saved 20%...... and got free shipping to boot. The 6' kit comes with 6 cooling fans and s boat load of mounting hardware, so I figure I did OK.
Personally I think they are a pretty good deal, if you think about how to best use them. 4 nanos would handle most 4' tanks pretty well and look really clean and finished whether hanging by themselves or tied together on a rail, or just in the canopy. When you consider how nice they look and everything that comes with them it's hard to beat for DIY on many projects. Not to mention no drilling and tapping and you can still remove LEDs unlike glueing them on to a cheaper heatsink to avoid drilling.
Standard Pin arrangement for a 4 wire fan should be this- if you listed the wire colors in the order they're arranged on the connector.
Black= Ground
Yellow= 12V+
Green = Tach
Blue= PWM input
Proceed with Caution though, Not all fans follow the standard pin arrangement.
The Fan produces a "tach signal" as it turns. In the case of most computers, the signal is monitored to determine whether the fan is running or not. If the cooling fan in your computer were to ever fail- the Computer will know and take steps to avoid overheating the main processor.
Thanks O2,...I started thinking about it while laying in bed this morning, and I understand it now,...a tach is a tach. My controller (Jarduino) lets me know speed. On the controller build page, the fan control wire colors are shown. Sometimes a little sleep ,things become clear :thumbsup:---Rick
Yep,...just checked Zalman site,...same lay out :beer: Thanks!
Minor update, I finally got my mitts on some A6211's.. I had to order samples through my "local" distributor.. Means the chips cost nothing, but wait until I get the bill for fedex express to canada! In other news, one of the caps on my board (the 47uf) I used the wrong form factor for, so I will have to fudge that (ugh). Since it's just a PS filter cap, I wonder if you can't just use one larger cap across the input to each board?
LOL- Can your "local distributor" get more????? Or can you hook Rick and I up with your local "dealer"? tehe.
From my experience with this driver so far, the 47uf cap is just a PS filter. It's not terribly important. I've busted a few off my little drivers due to careless mistakes and it doesn't affect the driver's operation.
I bought them from the highest rated seller that I could find on Alibaba and used an Escrow service as a go between. I also made the payment using PayPal, so I've got a couple layers of protection, just in case they tried to screw me LOL.
I'll test a few of them out after they arrive. It should be fairly obvious if they're fakes or not. I'm optimistic, as their price was inline with what suppliers here would charge for them based on the quantity that I ordered. I ended up paying $.79 each, with delivery to my front door. Not to shabby IMO.
I'll keep my fingers crossed. I just had a go a round with the little copper heat sink seller. First order never showed from a 12-18-2013 order, so I have another order on the way. Anyhow fleabay stepped in and they just refunded my paypal today.
Thats a good price, and fast shipping

LOL- If they turn out to be legit, I'll have enough spares to pass around and I'll put however you many you need into the mail for ya. I'm going to let my order of 100 stand at Digikey for the time being, as I'd hate to cancel it, only to find out that the chips I bought from China were "duds":rollface:
