Has anyone made an LED driver based on LM3463 6 channel driver IC?

Uhhhhh- yeah, don't pull the jumper while the driver is in operation. Bad things happen. I learned that lesson the hard way.(Good thing I've still got plenty of A6211 chips)

Let me know when you get your hardware and software sorted out. I'm looking forward to seeing what you come up with. I'm struggling right now to adapt some code that features Geocentric timed lighting periods. The code I'm using has some timing "bugs" affecting my PWM fans & Lcd, causing them to shut down at weird intervals. I'm trying to sort out the problem, but may just have to scrap the idea and go with something simpler. LOL

Hmm. Sounds weird. Care to share the code?

I'll let you know when I've got something working.

That heatsink looks a beast! I'm trying to shoe horn my solution nto a tiny space which is causing lots of problems. Considering losing the lid and going open top, but it's not an option the missus likes :(

Wife out of town,...you be like Santa in his workshop,..all you need is some elves:lmao: Thats one big heat sink,..with the fans should run cool. My board is cool to the touch, but I'm only pushing 700ma through it.I'm going to do some testing tomorrow with the top on the box I have it in. I tried it with the top on for a short period and the temp went up, but not out of the chips limits.
On your code,...why don't you just download the Jarduino program. I does lighting,...dimming, times on/off, and its free.:beer:

I'll be looking for pics, of the finished 6 footer,...last 6 footer I had was in Cabo :bounce1:---Rick

LOL- I'm dumping the "Elves" off at school first thing in the morning. Besides constantly getting underfoot, and chirping "Daddy- What's that for? What does it do? and so on.... I'm going to be "proactive" and eliminate them from my workspace while I have the chance.

I like the Jarduino, but it's firmware is too large to fit on the Atmega328 that I've got built into the 5 channel drivers. LOL- soooo many choices, sooo little time.
 
i need to order my 12V SCW and then i can start looking at this :) get were your coming from on the So many Choices
I also what to hook up a screen so probably go for the i2c option :) Many Be have it with Buttons
Need to start looking at that next
 
lol O2,...I watch my 3yr old grand daughter often as it seems I'm the one available,....can figure on 8hrs of Sponge Bob lol,...luckily hes kind of funny.

I don't know a 328 capabilities, but maybe you could pick apart the Jarduino code,...copy & paste to a new sketch---Rick
 
OH MY GOD..... Vero 18's are STUUUUUUUPID BRIGHT! Led efficiency sure has come a long ways in the last few years! I just finished up my new 6' Makers Heat sink build only to discover that I didn't need 1400ma or 1000ma to get decent output from these newer Leds. 12 of these at 700ma is more than enough! The best thing is - I'm able to run it all off only one 350 watt supply.
The 5 channel A6211 drivers are working beautifully, and don't even get warm to the touch. I spent some time over the last few days cobbling together some dimming control code that features 10 bit resolution, an I2C display & a DS18B20 temp sensor. It's been running on my test rig for a couple of days now, and has been stable so far. I know that's not as buttery smooth as 12 bit, but I'm cool with only 1024 steps at 150Hz. It beats the heck out of 8 bit and 255 steps. I'll post some pictures of the led light and the "lowly" Plant Tank it's over now some time this weekend.:dance:

Great news any chance of the code dude got my 12v scw on order just need a psu now any recommendations :)
 
How's this for clean wiring? I didn't have to solder anything, just drill 24 holes -lol.

A shot of 1 of the (3) 5channel A6211 drivers nestled between 2 cooling fans.
I decided to mount them right side up.This made making connections really easy and will make adjusting/servicing the driver controller much easier.

Here's a shot of the 20x4 I2C lcd display that shows what I've managed to program into the software so far-

That's it for now- more work to do!
 
Clean setup and great design. Look forward to maybe getting one of these boards from you for my next setup. Thanks for all the work.
 
what are those bridgelux's? I'm sure it was mentioned in the previous 13 pages I'm sure but for some reason I'm drawing a blank :(

These are BridgeLux Led arrays from their VERO line of led products. The VERO leds range in size from the small VERO 10, to the medium sized VERO 18, on up to the VERO 29. They are the American made BridgeLux leds that are available in certified bins, not the cheap Chinese version. I bought them from DigiKey for around $18 each for the 5500K "Cool White" to $23 each for the 2700K 97CRI "Warm White".

I bought these to provide lighting for my "Planted" tank. That's why you don't see any Royal blue or other colors in the mix. "Planted" tanks require more Red than their "Reef" Tank counterparts so that's why the leds I purchased range so low on the Kelvin scale. I'm trying to replicate the color of Sunlight "as seen by the human eye" under 2 feet of water in the Amazon river. Lol
 
02 you have a link to those LEDs might use them on my planted tank I'm not happy with the ones I got off eBay
 
Thanks 02. My daughter is into planted tanks. I built her an array using a pair of Mean Well's and some Cree's. Plants love them and agree about the blue.

One of our Bio Cubes is using Phillips / Luxeon and another of our cubes Cree's. Anyway, nice set up. I've been out and still tend to fall back to the Cree or Phillips/Luxeon but now I'm seeing more and more people using these sort of clusters I guess. I'm going to merge two of our 29 gallon bio cubes into a 40 breeder I picked up this weekend so was re-reading the thread to see what sort of options I have before I go back and pick up a quad driver from Steve's with the Luxeon LED's.

Thanks again. Appreciate the information.

Lol- No shortage of dirt here! I've got plenty of "mulm" to go around. All I need is another 5.1 quake, like the one we had here last week, to toss my substrate a bit and force the "mulm" back into suspension.

Nice of you to drop by "Oreo". I'll be sharing more about this build on our other Forum. Lol

:beer:

search for them on octoparts, there are many sources. the vero 10 actually has the same form factor as a star chip but has almost twice the output of a luxeon M for under $6. for a planted tank or even for the main whites on a large reef a half and half mix of the high CRI and the cool whites would be super!

I didn't realize how crazy powerful those chips had gotten until I looked them up today. the vero 29 has some models over 16,000 lumens!!!!!!!!!!!!!!!!. Efficiency is even on par with all the cree and luxeon chips being used these days, better in some cases.

Here's a thought:



How about putting some basic PWM signal generating code and fan control code on the 328's local to each board, and then control them in a master/slave config by a Mega with Jarduino, over i2c?



Just a thought I have been thinking of - but I have no idea how to implement it.
 
I've been wondering about that, but also have no idea how to get an arduino to talk to an arduino over I2C. Might have a google in a mo :)

Was having a play with one of O2surplus' boards yesterday. Got a USB FTDI interface and was just using that for power & serial monitor whilst playing with onboard PWM and a single XTE royal blue. Damn they're bright on 1.4A :)

Think I will swap to I2C PWM (PCA9685 chip) tho, for higher resolution.

Very nice boards tho - thanks O2surplus :D
