I learned that Make Magazine vol 47 is now on-line.

So here is the link for review:

MAKEZINE – vol 47

make 47

It is my understanding that the Projects pages link has not been activated as yet.  This is where details of the build can be found.

Arduino Sketches are found there as well.

But understand it is only starting code that will be added to and developed as time goes on.  Right now the UNO sketches only handles a timer functionality.  As people build the Gardens and report back their code updates I will be posting them here for all of us to learn from.

There is also a IoT Sketch using the code generated by Temboo that sends a SMS message system that again is starting code.

I have to point out that I DO NOT support the sketches from a technical perspective they are purely for reference and a starting point for people to use and develop on there own.  As I build out the interface on the project I will be posting code and sketches that work and would be of interest to the readers of this BLOG.

Also I have released some Instructables that support the article from a build perspective.  More are to come as they are developed or change made in the design of the Balcony Garden.

Knowing tempetures in aquaponics is very important. I track outside temp, media temp in center of grow bed, media temp at top of grow bed and fish tank temp. I do this for each grow bed. I track this so I know the impact it has on DO (dissolved oxygen) and what I can grow and when. Case in point, once my media temps goes over about 72 degrees F my Cilantro bolts (goes to a flowering state) not good.

Being this is aquaponics it is important to use only stainless steel item in systems or fish encounter problems. There are a number of DS18B20 probes being produced, but the majority are in a steel case.

Not finding any stainless steel probes I resorted to building my own. Very labor intensive process. Lots of time in sourcing parts, manufacture of the tube casing, testing each step in the process. Total cost of each probe came to around $7.50 not counting my time which came to about an hour per probe.

I was reading another blog about arduino and found a new site called http://www.yourduino.com. Decided to check it out. It looked good so I checked out the sensor section, there they were – the probe I had been looking for and at the right price. Needless to say I place my first order. They came, I hooked them up tested them and now I have a new source of reliable Stainless Steel temp probes.

I will be blogging about the connection process and testing and about pulling off the HEX code of each probe. This is important stuff when working with one-wire protocol. This is now my new standard to be used.

I was asked by Make:SF to talk about aquaponic automation.  I have now developed a desk top unit to test all the sensors and arduino controllers.  The meeting will be held Tuesday March 8th in San Francisco.  I will have a working demo of the auto cycle of my controller working all phases of the aquaponic unit.  This will be a first for me as I have just completed the arduino sketch to handle the auto mode of the controller.
