Open Source Controller
« on: December 01, 2011, 05:06:13 PM »
So I have been wrapping my head around alot of different features that could be used for an aquarium controller. So far I have been using my sensor shield for the Arduino as a base for the design. Have included the Atmega328-P chip with an Uno bootloader (means selecting Uno model in drop-down list). The included sketch that will be on the controller shipped will control the features below right out of the box. There are breakouts for an optional keypad and ethernet shield should you decide you'd like to work with the open-source sketch to code in an addition of a menu system using the keypad or running a web-server to display your tank parameters on the Pachube website so you can see what your tank is up too online while at work or away from home.  This controller will be what i'll be donating to this site for a contest possibly once a month when we finally get noticed and alot more members and hopefully more manufacturer contributors for contests.

What it includes to-date:

Atmega328
DS1307 Real-Time Clock
pH Sensor
ORP Sensor
4x Lighting Channels
2x OneWire USB (DS18B20 Temp Sensors)
1x Analog USB (2 Float Switches)
3x I2C USB (Can be used to add an external 20x4 LCD screen, 8-channel relay outlet box, possibility of external PWM for more lighting channels)

Optional: w5100 Ethernet Shield Break-out (for a web-server)
Optional: AD-Keypad (for a menu system)
Optional: GSM (to recieve text messages at a determined interval on your cell phone)

Planned additions:
Bluetooth Module with Android App



This build is a few months out to even test as I am unfortunately working on a limited budget. I have been looking around for financial backers for this project as well as 2 others. This project will require $500 for PCB manufacturing and parts needed. If you would like to contribute to this Open-Source Controller please feel free to come see me here. Those contributing $125+ will receive the controller head unit as well as an honorable mention on the website's shopping cart as contributors as well as within the coding of the controller. For contributions of $50+ you will receive a controller unit at a discounted price with honorable mention and donations of up to $49 will have your name immortalized online and within coding as a contributor.

Those of you who have donated $50+ will receive the relay controlled outlet box at cost once completed.

I would love to make and label this controller as "UKReef Edition" with website address printed on the boards as i'd like this site to completely "host" the source-code for this design and build. Part of the sales would goto this site for upkeep and advertising. If anyone has any questions what-so-ever on this project, please feel free to ask.

I've re-designed the board to include 0-10vPWM signal. Added 4 buttons for a menu system, removed the analog input signal....So right now there are pinheaders for 0-5vPWM and 0-10vPWM (4-channels), 2x I2C and 2x 1wire using usb still, added holes for mounting either a 16x2 or 20x4 I2C LCD screen with pinheaders on board. Hopefully within another month i'll have the cash to order the boards and parts needed to test it finally as sales for me are slow but going. At present time the default programing does on/off and durations based of the Great Barrier Reef ,weather patterns, lighting and the menu is for setting time. Soon as I can get the updated relay boards also i'll be adding a feed and water-change mode into the menu to turn pumps off in either a per-determined amount of time or being user selectable with-in the menu system.

It is very good. I read that feeling that I know what is new knowledge for me.
