This is a tiny little guy compared to the car projects of the past, that's for sure!

Took a side deviation and am working on getting my 16 channel PWM controller working.

That is bright for being just 25%... Especially just a single channel!

It is crazy bright. The amount of shimmer is nuts. I see why people love halides / kessils etc. ONe thing I'll have to build right away is a 'canopy' of some sort to shield the room from the side view of the LED. it's crazy bright at 25%.

some top down pictures (my phone is having problems after I dropped and shattered it this morning) I am very impressed with the colors- I am currently driving all channels off 1 dimmer so I haven't played with different %'s of colors but once I get my other piece working it'll be fun.

(PS Keep in mind my wife left my lights on 24/7 for 4 days a couple weeks prior to this due to bumping the timer so I had some serious bleaching)

How wide is that cooler at it's widest point? You could use a PVC coupler for something like 4" or 5" pipe and paint it black for a really nice finished look. Just need to vent it a bit for the fan... Have the LED approximately an inch or two into the pipe and that will shield the rest of the room and eliminate a little bit of the light spill as well.

I'm going to try to not cover the cooler at all if possible. the "hanging" approach is obviously OK especially for prototyping but not ideal for me long term. I'd like a rigid mount that can fold the light up out of the way if need be, so it can support the weight of whatever 'canopy / blinder' i have to build..

Anyway, proof of concept very much a reality now I can start deciding on how to build the 'blinder' and how I"m going to protect the LED from the water etc.

For the folding part SUV rear door gas shock would work if you kept it light enough. (No pun intended)

If it was going to be heavy you could always build in linear actuators to power lift the system. This would of course add just a pinch more techiness to the build ;)

Damn thats a nice setup there.

So its only that one chip of LED's thats the project then?

PSH! That'd be a TINY Project. It's three of these chips, they're going to light a 180 gallon tank. The controller will be handling all the light control as well as tank control. That's the next part. I've been fiddling with combinations, here is an example of what I might use for night mode:

Image

That's with the two blues on 15/4000, the two whites on 5/4000 and the UV on 500/4000

(Gotta love UV)

Anyway, the idea is that with the controller gradual transitions from time of day to time of day can be accomplished and noticed. Sunsets, sunrises, etc.

I got the boards so I can start to source parts and begin my build! Did you get your hammer corals?

So do the drivers themselves get warm on the boards or do they remain cool? I am trying to figure out how I would like to mount the LED driver boards to protect them...

Haven't gotten them yet, Matt is very nicely holding them (probably the happiest they will be) my team is releasing a new version of both of my products this week so it is VERY busy around my house for the next few days.

Drivers dont' get hot at all, could mount boards in something as long as you have a bit of airflow easily.

Get the dip things though so you can take the drivers in and out without soldering, wish I would have done that after I fried a driver ;)

Cool, thanks for the info! I cut your frags from the bottom half of the colony so a few heads were shaded but give them time and they will color up nicely. Trust me when I say you cannot kill these things as they are hardy as can be ;)

Good deal for me. I haven't killed much but lord knows it's just a matter of time.


While i'm rigging up a splash shield, I ordered up the next step:

Will be getting the ATO and relay controlled outlets in place ASAP.

:D

Also, while the freezer 7 pro revision 2 seems to be doing a fine job of cooling the LED I did order teh freezer 13 for the next pendant. It's rated for 200 watts of heat and has 4 vs 3 heat pipes. It's also offset a bit so it might be easier to hang/mount. Not sure. It is basically identical in size though, which is nifty.

ATO

Postby iced98lx » Tue Apr 30, 2013 3:50 pm

Well, got some floats and a pump, here is my ATO logic so far.

This creates an interrupt port that can trigger events:

Code: Select all
static InputPort SumpLevel1 = new InterruptPort(Pins.GPIO_PIN_D8,false,Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeLow);


And then on startupI assign an event to happen if the interrupt fires (water drops) and check to see if the float is already down, if it is, the event won't fire as it fires when it goes down, not while down, so I have to manually fire the event:

Code: Select all
            SumpLevel1.OnInterrupt += new NativeEventHandler(waterLowEvent);
            if (SumpLevel1.Read()==false) // check for low water on start up, if so fire the event manually.
            {
                waterLowEvent(0, 0, DateTime.Now);
            }
            Thread.Sleep(Timeout.Infinite);


Now, the event that is being fired, I replaced turning on / off relays with Debug.Prints of what is going on:

Code: Select all
static void waterLowEvent(uint data1, uint data2, DateTime time)
        {
            if((DateTime.Now - _lastFire).Seconds < 30 || _doneFilling == false) return;
            else
            {
                _lastFire = DateTime.Now;
                _doneFilling = false;
            }
            ledOnboard.DutyCycle = 1;
            Debug.Print("Pump Running");
            while(SumpLevel1.Read()==false) //while still too low
            {
                Thread.Sleep(1000); //give it a 1 second pause so it doesn't flutter on / off
                Debug.Print("still low on water, pump running!");
            }
            //finished filling, sensor says full.
            Debug.Print("Pump Turns Off");
            ledOnboard.DutyCycle = .25;
            _doneFilling = true;
        }


As you can see, I check to see if the event has fired in the last 30 seconds, and to make sure it's done filling (can't fire two events at once).

Then, I set a flag to say it's filling, and set the last fire time to right now. I light up an LED to tell me that the ATO is running, then go into a while loop. The while loop says basically "While the float stays down, wait for one second, then check again" once it's up, the pump turns off, i shut off the LED and set my variable of _doneFilling to true.

I'll add some additional floats for backup/etc and monitor the level of the ATO container as well eventually but it's a start to test the float.

Alrighty, so a run down of what is done so far:

Using a Netduino Plus 2 my controller does the following:

  • Sets the time via the network
  • Uses a float switch to fire an ATO via relay when it falls
  • Uses an adafruit 16 channel PWM to dim up to 16 channels of LED lights (currently 5 channels for 1 LED pendant, there will be 3 total, plus a PWM for the ATS)
  • use a DS18B20 temp sensor to check the tank temp and turn on/off a heater via relay

Theoretically it's ready to run my little test reef (29 gallon bio cube). I've got a little more hardware work to do (splash shield for light, fan wiring, tidy up the controller, wire a few more relays) but it could work.

Things that will be added soon:
  • Small LCD Screen for System Status
  • LED's to indicate ATO running, heater running, etc
  • "Feed Mode" where pumps (which need to be added to relays) turn off
  • Fade functions for the light
  • utilize fade function and time to program sunrise/sunset
  • additional float switches to monitor for disaster situations
  • water change mode that disables ATO feature

Things to add later:
  • Other sensors (pH, ORP, conductivity)
  • water sensors for floor/area
  • weather patterns for lights (random cloudy days etc)
  • power head control

I've attached the source here, if anyone cares to look at it.

Doing my first sunrise simulation as I type. Can't wait to coordinate 3 of the pendants to do some awesome things. The possibilities, are endless!

Going to have some time finally to work on it tonight, my first free night in probably 4 or 5 months and I roped it off to JUST this. I'm going to mount all my boards on a backer board, wire all my outlets on my power strip and get the controller board mounted on top of it. Hook up all 8 relays up, and then focus on programming. Hopefully get my LCD going, some more LED functions, etc.

end goal is to have it packaged much better by the end of the night.

Day 3 of full LED lighting, color is actually starting to return to a few coral pieces. I'm not saying the LED is that much more awesome than the CF it replaced but what I am saying is that it actually gets light to the poor things.

I added a glare shield about 1 inch big so it doesn't blind me out quite as bad in the office, seems to work well, might go slightly larger.

Coral Notes:
Pink Mille turning bright green vs the brown it had been under CF

Green Acro showing much better polyp extension and skin is darkening vs the bright white under CF

Green Birdsnest: Good polyp color darkening skin

Bird of paradise: showing hints of green no the topmost areas skin still white, polyps white to very light purple

sour apple birdsnest: darkening skin and polyps with a hint of green on the topmost polyps

pink birdsnest: fighting cyno but still darkening up a bit vs bright white before

Red Hyacinth birdsnest: darkening up polyps starting to purple, also battling cyno.

Lots of growth on the birdsnests, some signs of growth starting on the pink mille.


LPS is all going gangbusters and coloration is really picking up.

Awesome! Now all the lighting zombies out there are yelling PAR, PAAAR PAAR!!! Let's see some numbers as soon as you get your hands on a meter.

Let's see a pic of what the light looks like at this moment. I'd like to see what you did for the shield.

Can't wait to get a meter under it though they say those aren't as accurate with certain wavelengths of LED's.

This is with the lights at basically 40% brightness:

i live a couple blocks away I should be fine, If not, I got a couple welding helmets in the garage.
It probably would have been easier for him to put the tank inside a tanning bed

I need to write some fade methods and a few other things but in order to get it into production I've just set up a simple schedule so that it's daytime after 8AM dusk after 6 PM and blackout after 9 PM.

Working on getting my power strip and ATO working today, then I'll cut heater control over to the controller and fill up the ATO tank and see how it goes for a few days.

I wanted to note that I allowed my ATO to function un-assisted for the first time this morning (when my new pump arrived). I know this isn't much of a big deal for most, but watching it go for the first time was very satisfying. I had to set it to wait for 2 seconds vs 1 while filling due to how slowly the aqualifter pumps, but overall it worked great.

I also have working fade methods, so the lights fade in in the morning, fade to dusk setting for a while, then fade out at night. It also turns my powerhead off at night.

Question about the LEDS.

Would running two of these on a 55 be to much? Could one work or wouldnt it have enough dispersion?

Would they work for or is there a version of these that would also work for freshwater?

You could do 2 but you'd need a good shroud as the front to back light spillage would be intense. Not sure on salt vs fresh or what these would do over a freshwater tank though.

That much light going into a fresh water tank might just bleach the fish white..lol Looks great, I wish I had the time and knowledge to code all that stuff. Building the lights are the easy part, coding blows.

was a little concerned that the ATO was running for a few seconds every hour it seemed during the day:

Code: Select all

so I checked my salinity quick this morning, 1.026, just where I set it. VERY happy with how this is going. Have used about 1/2 gallon of water in about a 24 hour period.

I have words for aqualifter pumps, beyond that I will leave that topic alone.


Anyway, time to add logging to this setup, but I'm having a hard time getting motivated. Need to wire up my 74HC595 shift registers so I can control all my relays + some other stuff. Also need to work on my LCD.

I think I'll break down my logging into two sections:

Things that are observed
  • Temp
  • Ph
  • Salinity

Things that are controlled:
  • Outlet Status
  • Light Status
  • ATO & Level status
  • Current text on LCD

I think I'll keep it pretty simple and pass them as values in the URL and sort them out in PHP later. I duno, I keep thinking about how I can scale this up but frankly it's just written for me anyway lol

Well, I got motivated enough to set up logging of temp at least:

http://reefin.net/


will show you the last temp recorded in the biocube. It only updates every 1/2 hour, so.... don't hit refresh a bunch to watch it fluctuate. Though it handled every second fine, I doubt I'll want that much data :)

LCD functioning (Bare minimums, showing temp right now)

Will needs big management abstraction around it though.
