big diy multichip led lighting with realtime weather

I think you explained what I was asking :)

There is data coming from the Cayman Islands, a timeshift is applied to bring this data in line with your tank lighting period, desired sunrise / sunset. So it uses real data, at a different time to suit your time zone.

Yes, correct. But the shift is pretty minor or zero (in winter time). The sunrise on cayman islands starts at 6:00 AM which is 13:00 (12:00 in winter) here in germany, that is nearly perfect for me. I always had late sunrise/sunset times at my tank, because i want to enjoy it, when i come back home from work. so my lighting period goes from 1:00 pm to 1:00 am.
 
could you post your code for this. i am doing something similar and am stuck on the programming
maybe i could get some idea's from yours
i am using mega and rpi also
thanks

hi,
tell me, where you are stuck particularly and i try to send some code for it, or help you somehow with it.
 
Nice job on the tank Michael.

It looks like you are using 1 Meanwell driver per LED?

I use the same Adafruit PWM driver on a Raspberry Pi. The work pretty good.

In a photo for your add on lights, it looks like you hand wired the drivers on project board. Did you ever consider drawing up a board layout and using one of the Chinese PCB houses. They can be quite reasonable for 10 boards.

For the weather info, what service are you using. I had a look at Weather Underground (http://www.wunderground.com/), and they seem to have some free API feeds, but was curious what you were using?

thank you Dennis.
You are right, i use one LDD per LED and special drivers for the 100 watts. They are all soldered to those little solder boards, dont what they are called correctly:o I am not an electronics expert, so designing a PCB was not an option for me, though I really like custom PCBs.
Yes, the weather info is taken from wunderground.com, they have some real time stations and a nice good documented API.
 
I'm currently working on a led aquarium too.
I'm also using some of the things that you are using. Could I ask you for your source code from the raspberry pi so I can use it as an example?
I'm not going to use it exactly the same as you are, but I want to see how you used it and make my own code instead.

hi jorim,
no problem, but the raspberry is only responsible for querying and sending weather data ( some dead simple string commands) to the arduino. Furthermore its serving a web app to control the fixture ( with, you guess it some dead simple strings). Still interested in the raspberry code ( java eclipse project)?
it was quite hard ( for me ) to get java running as i wanted it on the raspberry....
 
Well, since you work with Java, it's not helping me ;) I'm trying to work with Python and nanpy.
Wait... maybe your code can help me out. I can read Java for a bit, so I should be able to convert it to Python (I hope).

sorry for the late answer, i was a little into my other hobby ;)
here is a python script that i used before i switched to java. if you use it, please dont forget to create/use your own API key from wunderground. i have removed mine from the script, so it wont work without your key.

Thank yo so much am.gee. I think this is going to help me a lot with my project.
If i have questions about it I will let you know.
Thanks again.
 
i have been working on mine
i have all of the hardware, i am using some code from reef angel for the arduino.
it does a nice job on the weather sim. now i just need to get the rpi to scrape for weather and have it change a few byte's in the arduino code.i only use 3 drivers now so i have 1 extra for more led's i i need it
my pi has a 3.2 in lcd, i have a few for the arduino's too but i dont think i'll use them on this. i ran stilo's software with the mega for awhile.
here are some pics so far.

Nice build!

Do you have a manufacture list of where the led components can be bought?

can you comment on using the raspberry pi to send tank alerts
 
Good Day Michael, Hope you are well.
I am very new to the hobby of salt reef aquariums but like you I am not to impressed with the lighting options out there.
USA Current has a nice system but i am not sure that it would be efficient enough as i am building a 1000L tank and would need way to many lights.
Would you be able to share the schematic and component list of all the items you used to build you LED light as I am extremely impressed with this.

Thank you in advance Terence
