Arduino Shield Design Standards

Posted Mon, 02/01/2010 - 12:52 by andrew1056

It seems like I'm not the only one who has run into problems with Arduino shields holding me back from doing projects. Here we're going to discuss a standard for designing Arduino shields which should make the whole system much more modular and open up new realms of possibilities for the Arduino.

The idea is simple. When designing a shield you have certain pins that you can use and your shield must allow the user to be able to change them. Read more »

Cloning Partitions To A New Disk

Posted Thu, 12/10/2009 - 19:43 by andrew1056

 I ran into a little bit of a problem the other day. My root partition got full. A year ago I would have thought it would never happen, but installing mythtv and a host of other applications just filled up the 25GB partition. I blame apt-cacher-ng for most of it, but it's helped save my bandwidth. The reason I'm doing this is because mI can't resize the partitions because /home is an XFS partition (for mythtv). I wanted a bigger root partition, but can't resize the current ones. Here's what you can do. Read more »

Arduarium Controller Gets New Code

Posted Fri, 12/04/2009 - 14:01 by andrew1056

 After what seems like forever (but has only been about a day) I've added in 300+ lines to the Arduarium Controller code. It's really starting to behave like an aquarium controller since I can now monitor PH. Read more »

Arduino PHORPDuino Shield

Posted Mon, 11/30/2009 - 16:52 by andrew1056

The Arduino BNC sensor shield is designed for very high impedance low voltage sensors (pH, ORP etc.). It has 2 BNC connectors as well as a variable resistor to control the gain. Read more »

Arduino Port Expander Shield

Posted Mon, 11/30/2009 - 16:49 by andrew1056

The arduino port expander shield is an I2C shield that adds 16 digital outputs to your arduino. You could use it to control LED's although it was initially designed to control SSR's on an aquarium. Read more »

Arduino I2C / SPI / Onewire Shield

Posted Mon, 11/30/2009 - 16:46 by andrew1056

The Arduino I2C / SPI / Onewire shield is pretty much a board with pins which would allow you to connect these types of devices. The I2C already has the pins pulled up and the Onewire portion has the pin pulled up as well. Read more »

Arduino RTC / EEPROM Shield

Posted Mon, 11/30/2009 - 14:26 by andrew1056

Originally the Arduino RTC / EEPROM shield was going to be incorporated into a single board for an aquarium controller, but since none of these boards exist (to my knowledge) I decided to break them up into shields which you can use. Read more »

Arduino ByVac BV4218 Complete Library

Posted Thu, 11/19/2009 - 19:33 by andrew1056

Well, after quite a bit of hair pulling the lcd and keypad of the ByVac BV4218 I2C module now works. Below are the directions to get the keypad and lcd working. Read more »

Arduarium Controller

Posted Mon, 11/16/2009 - 19:30 by andrew1056

The Arduarium Controller is a project to build a modular open source aquarium monitor/controller. Right now it's in the beta stage as the PCB has been designed and sent to the fab house. Read more »

Aquarium Luxeon LED Test

Posted Thu, 11/05/2009 - 16:27 by andrew1056

It's done! After weeks of testing designs that really didn't work I've finally got half of my new luxeon LED lighting system up and running. I personally think the light looks a lot better, and the polyps and anemone seem to agree as well.

If you want to read about my failures you can visit Aquarium LED Lighting; however, here we'll be sticking with the successes. Read more »
