My DIY Tank & Light Controller + DIY LED Cannons

Postby iced98lx » Tue Dec 18, 2012 2:24 pm

Going to document the progress of my LED cannons for the 72 inch tank here. I'm just about ready to start ordering parts.

So far the plan is to use 3 100LED multichips to light the 180. Utilizing 60 degree optics, we should be able to grow a lot of coral.

The Chips i'm going to use are a knock off of the "Dream Chip" LED Chip, and are about $90 a piece on ebay, and contain the following:

Channel 1) 10S x 2P 10000K 30-36VDC 700MA
Channel 2) 10S x 2P 455nm 30-36VDC 700MA
Channel 3) 10S x 420nm 30-36VDC 350MA
Channel 4) 10S x 2P 445nm 30-36VDC 700MA
Channel 5) 10S x 2P 15000K 30-36VDC 700MA

As you can see, 2 white channels, 2 blue channels and a UV channel. I'll be controlling them with 15 drivers (ability to dim each channel on each chip). I"m going with the LDD-700H's for blues and whites, and the LDD-350H's for the UV's.

To mount this all I'm having some custom PCB boards done up at iMall. A RC member designed them to put 5 of these drivers on 1 10x10 board. I'll be ordering 10 (have to) so there will be 6-7 left over if anyone else wants to try this.

Power supply will be a 48v 8amp meanwell, powering all 3 boards.

Each driver will take PWM dimming, so I'll be able to set up some pretty awesome/complex dimming scenarios when it's done.

The way it sits now, here is the price breakdown:

Drivers, Power Supply: $138.51
PCB Boards: $33.88
Terminal Blocks: $61.60
LED Chips: 3@ $90= $270

Total: ~$504

Looking into alternate options for terminal blocks, they're a silly large part of the order otherwise.

Yea, issue is doing molex plugs on the board, then plugs on the cords plugging into the board, ordering in quantity, doesn't make it any cheaper, sadly.

Ahhhhh.

Suppose you could go savaging old monitors etc for connectors. Then you could be doing the "green" thing. :D

Changed up the board design a bit to reduce cost on connectors, went with super generic 2 place screw types, now the cost for 3 is $455 roughly.

Any chance you can post a material list with model numbers or links? I really want to follow along and see your results. This is exactly what I want to do with my 125, but I want to see results and color spectrum. You are doing this right so I really need to see some pics.

Excited to hearound and follow results. I want leds on my 125 as well and can't afford 3 lights at $700 each to light it :/ I'd hate to go with T5's and moonlighting which would cost close to what you have mentioned!

So the skinny:

This is going to work out to about $210 for the first light, and $120 per light after that for 2 additional lights. Over 3 requires another power supply, over 10 requires another run of boards.

(Per Light)
Drivers
Power Supply


Terminals
  • http://www.ebay.com/itm/100-PCB-Screw-Terminal-Block-2-Pole-5mm-Pin-Pitch-for-24-12AWG-Wire-300V-10A-/110988130413?pt=LH_DefaultDomain_0&hash=item19d768786d
    (enough for all of them)


Chip
  • http://www.ebay.com/itm/DreamChip-LED-100w-Panel-5-channels-in-a-chip-best-collocation-for-marine-tank-/400376396438?pt=LH_DefaultDomain_0&hash=item5d384afa96
    (will take $90/shipped per chip)

Thermal Managment
  • 100w or better PSU cooler from a p4/athlon. I happen to have a bunch laying around, so $FREE

Controller:

Somewhere in the midst of going with a simple controller (google typhoon LED for one) I decided I wanted to be able to control all 15 channels independently. this requires 15 PWM outputs. I was going to do an arduino board and a shield, but I'm a C# developer by trade, so when I discovered netduino the route was obvious. Starting as a simple LED controller it became obvious that I should just build an entire controller. Tomorrow my Netduino plus 2 arrives, by friday I'll have a temp sensor, real time clock, relay setup to control pumps, and the PWM shield to control the lights.

The controller will log to another server via HTTP posts of various parameters, and will take http posts to control things remotely. Individually it's all been done on either netduino or arduino so it's just a matter of me pulling together the pieces into one project.

Things to log

Things to control
  • 15 PWM channels for dimming meanwell LDD-H drivers for LED's (https://www.adafruit.com/products/815 )
  • up to 8 120v Outlets. Ordered http://www.amazon.co.../ref=pd_sbs_t_1 for now, will package up neatly when I'm ready.
  • I'll need to do several things on a schedule, so I've also ordered an i2c Real time Clock.
  • EcoTech VorTech Pumps (RF) //eventually, I will likely use the RF module from Reef Angel for this
I've sold off my Reef Angel (got the opportunity to return it, actually) and will work this system out on my biocube while demo starts on the new office to build the stand and cut a hole for the big tank.

Cheers to my (almost) wife for supporting me on this one!

Just been so busy at work, finally got some time opening up, and the controller will be here, getting light parts ordered, so once one light is done, controller is ready... minor things to get the tank going. So we're starting on the stand, and getting the room it's looking into going so that everything sort of comes together at the same time sort of. Probably shut down the biocube when we bring up the big tank, bring the cube back on line after we pull the back chambers out and drill it, use it as a QT when we're ready to add stuff.

Sweet.

I suppose now the theme music could be White and Nerdy by Wierd Al eh?

Ive looked at those arduino setups, but was having a hard time deciphering what they were trying to tell me.

Must be to much of a hardware nerd I guess.

What language do those unit use, ladder logic,assembly,??

Arduino's use a modified version of C, which to me was unappealing- I don't know C very well, and I don't intend to learn it. There are tons of boot loaders, firmwares, then the actual programming is called a 'sketch'.... Blah.

Netduino's use .netMF (http://www.netmf.com) which lets you code in VB or C#. I'm a C# dev, so.... That's when I knew I could do it. You pop it onto a USB port, open Visual Studio, program away, deploy and it runs- presto. The Arduino's are faster, since they don't have the framework on top of them, but I'm offloading all the graphing, etc to another webserver, so I should have enough speed with the Netduino Plus 2 (168mhz). There other faster NETMF boards (Hydra) out there, that are compatible with Gadgeteer, but netduino has it's own appeal. All of the parts I've mentioned I'm going to use I've found code samples on how to use.

Will your design on the cannons work without the DIY controller? In other words, if I followed your design specs, could I control it with my APEX? I understand there would be less control as I may need to combine channels, but would the possibility exist?

If you can provide PWM signal to control lights, these lights will work with any controller. If your controller only has 0-10v analog available with no add-on PWM module there is this: http://shop.stevesleds.com/Aquarium-Con ... arness.htm which will convert 0-10v analog to PWM. most would combine channels to basically only have 5 channels (one for each color). I like at least 5 channels as it lets you adjust each color, but 3 would also be feasible (two whites / two blues/ antic/UV). The Drivers are the key here, the LDD drivers are perfect for this particular build/task.

So I got my  N+2 today. HOLY CRIPES. Way better than I thought! Tiny, as well compared to how it was in my head. Real time debugging + easy to understand tutorials make this a great thing. Only thing is with the N+2 being new I didn't see a lot about how to do networking etc. I haven't updated my firmware yet so I'm seeing an incorrect MAC address which led to some initial confusion (Is the networking working?!) but after I figured out that indeed, it is working... super cool!! I quickly cobbled together a couple lines of code to make a web request and tell me via LED if it was successful:
 
Code: Select all
using System;
using System.Threading;
using System.Net;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;

namespace Hello_World
{
    public class Program
    {
        public static void Main()
        {
            // write your code here
            OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
            var myReq = (HttpWebRequest)WebRequest.Create("http://chrisuthe.com/robots.txt");
            var myResponse =(HttpWebResponse)myReq.GetResponse ();
            if(myResponse.StatusCode.ToString() == "200")
            {
                led.Write(true);
            }
           
        }

    }
}

 
SUCCESS!!  
 
 
Now it's back to the 8-5'er for a bit, but I feel good knowing I can upgrade firmware later today and get started planning how the software end will function.

Todays Progress:

Ordered:
1 x LDD-350H
1 x SE-350-48
From Powergate Express LLC

Ordered:
4x LDD-700H
From Mouser (they are basically tripple price vs powergate but in stock)

Power gate won't have 700's in stock until late feb (the 22nd) so I went this route since they got the power supplies in today (Ship monday) and already had the 350's in. Powergate is obviously the price leader here, but they admitted they were having problems keeping the LDD's in stock but did say they had big orders coming in in feb, so I'll wait to buy the rest of my drivers from them.

PCB's Ordered from iMall iteadstudio.com (Thanks for the design 02surplus!!)

Should have everything to put together a light by the end of the month.

I, unfortunately, have no understanding for most of this and therefore am forced to spend roughly $800 through RapidLED.com for appox. the same equipment lol. controllers, drivers and such. As we all can see, knowledge is the key to finance!! I have been doing my best to understand and follow along, while learning a few things along the way :)

Fine... I'll admit it, I am a geek... There are you happy ;) Anything with wires and electronics is fun. when you can mix wires, electricity, and saltwater makes it even more interesting.

Oh the breadboards... they bring back many memories of exploding LEDs and burning resistors from electronics class.

Looks like you have temp down. Are you going to have multiple tank control with this since you have the ability to name things well?

Dang!!!

Your slowly poking at my inner geek, and when he gets out, I spend way to much money for shiny "bass boats" LOL

Looks like you have temp down. Are you going to have multiple tank control with this since you have the ability to name things well?


I could have multiple tank control easily, but I will have only 1 tank to control lol - I will monitor the temp of a few other tanks (QT/Mixing) just because they're cheap and easy to do. PH is $100/tank to add the probe, so I'll probably only do the main tank. Likewise the Salinity probe is $150, so.. Only one!

It is good progress over here. You'll be able to easily build one when I'm done.

Not sure this is considered good value for money, depending on the final use. It just so happened that no other controller was going to control 15 channels of lights so writing my own became ok.

What's the cost to setup a little temp probe and controller like that?

So to set up just temp, it's pretty affordable:

$60 for the netduino plus 2
$10 for the power plug
$10 for the temp sensor
$10(?) for the resistor, hookup wire.

That could get you a wire coming away from the board with an RJ11 jack on it, plug it into a splitter, make an RJ11 jack on the end of the temp probe and plug it in, you can now monitor 1 temp. $10 more gets you a 2nd temp.

$10 more gets you 8 controllable outlets. (err, the relay board for it, you have to wire it up still)

So for 1 temp and outlet control you're at $100.

Add in a $100 probe, and you've got PH- $200 total and in my opinion a very capable controller.

Toss in $15 to build a water level sensor out of a pressure sensor, and you can do top off automatically too.

You could skip the breakout board and control up to 5 PWM channels for the LED's i'm building strait off the board, otherwise the break out board is $15 to do 16 more channels of PWM.

I'll have about $350 into the controller, with PH and Conductivity (Salinity) and my light controller. I figure about $800 for the controller and lights combo.

Damn...this is something you might have to teach me. Seems fairly affordable AND expandable.

One question on the power supply.

I have seen others re-purpose old hp printer power supplies for their power.

Have you thought about that or is this simply a cleaner setup for you?

Right, there are lots of options, I actually power the board completely off the USB connection right now but later will power it off a simple 9v power supply. Likely I have one laying in a bin and will use that. All the other high power pieces (lights) are powered separately.

Boards arrived, LED chip arrives today. waiting on some screw terminals, but they should be here this week. I ordered the wrong ones (woops) but have the PWM board and drivers soldered up so I'll probably get started programming thursday to control PWM's so I can test the lighting. Got my relay, ordered the box I'll be hooking it up to. Very exciting!

Thanks! Everything is really coming together nice!

Got my DJ Power strip today, just waiting for the screw terminals (hopefully today or tomorrow).

Can't wait to fire this thing up!

Every time I see this thread with an unread post I say inside "Ooooo did he light them yet.... I need to see these things lit up!"... It is coming together nicely for sure.

Are those leads pre-soldered to the chip for you or did you solder them yourself?
