Thank you
Hi,
greetings from France ... I would like to know if someone know any U.S. supplier which could have A6211 chip in stock or another chip which could replace it ? I looked at Digikey they can ship A6211 in April it's long
Here in Europe I can't find it neither.
I need to drive 10 CREE Led (let's say 32/34V) , at 1500mA, and my SMPS is 48V output. So far I found some chips which could replace A6211 (AL8806, PAM2863, NCV7691 for example) but can't find a chip which can handle both 48V input and 1.5A output. I also need PWM control and small package, SOIC-8 for example.
thanks.

Send me a PM. I've got some extra A6211 chips available.
A6211 = "Unobtanium" Glad I bought the 400 when I did! LOL:dance:
I can't, you are the boss and I'm nothing
I think you have to contact me first
Code:
Sorry, you can only send messages to the RC Moderator group until you have 10 posts.O2Surplus is not the boss (just the God of certain sections) it is that you need to get your post count up. I assume it's a security measure to prevent spammers opening accounts and PM'ing everyone.

From "boss" to "God" in only two posts!:eek1: LOL- Thanks Tim!

O2, I don't post on here either(use NR), but have been a member for a long time. I need a 4 channel PWM to 0-10v for my Apex. Pm me your info for payment if you have any & the price for the 4 channel board.
Thanks
Thanks
Ok- All you "low post count" guys can reach me at wak714@gmail.com
Let me know what you need and I'll do my best to help you out.

Hi All, I stumbled onto this thread after deciding to build my own lighting controller a few months ago. It all started when I got an arduino starter kit and got it to blink an led. Great! i thought. just need to wire up a few more of these and have my own aquarium led system. ha ha. well.. after few more months of learning how to code, learning about electricity, learning how to solder, learning how to use eaglecad, and spending many an antisocial evening looking at specsheets I finally have my own arduno controller with its own menu system and led driver! now i only have one question...
where should i physically mount everything?
my components are similar to the ones produced here so i thought I'd ask those who have bought/madeyour own, do you put your lcd on the front, driver on top of the lights and psu on the floor or everything in one box under the hood, or in a cabinet under the tank? for those who split everythng up, what do you do with all the wires everywhere?

Thanks! Yes this is one of the reasons I ultimately decided not to mount everything onto one pcb. Interconnecting (and using flywires) also provides more choices over the size and shape of controller.
