Since the problem with using a 5″ HDMI display was worked with the Raspberry Pi.  A new problem developed that needed to be addressed.  Running Arduino IDE on Raspberry Pi using the 5″ HDMI display at 800 X 480 resolution.  The problem is that the Arduino IDE bleeds off the edges of the display (see picture below).  The issue is that the Arduino IDE cannot be moved around to get access to the menu options.  So there is no way to check libraries or setting to insure sketches are being up-loaded correctly.  No new sketches can be opened either.  Major pain.

After some research and a little time solving the Raspberry Pi – Jessie with Pixel display issue I found a solution that resolves this issue as well.

I wrote an Instructable to document what is needed, so check it out if this is a issue for you.

I say this because I will be displaying my aquaponic – IoT – Balcony Unit  at Maker Faire next week in San Mateo.  To accomplish the IoT part of the build I have to use technology that allows for internet communication thus IoT!  Well there are many options available to accomplish this task – some not so easy and others not enough features to be effective for this project.

So my choice in this case is the Arduino YUN —

arduino yun

I made this choice because I had one (but had not used it as yet) and the fact that documentation on it is easy to find.  The other fact is that Temboo www.temboo.com uses the YUN as one of its options for their solution to the Internet of Things and I am working with them on this open source project so many others will be able to get up and running in short order and have simpler options to add additional capability based on the persons needs and I will not have to supply the customer support for any aspect of the code other than give everyone a stating point.
WELL –  that is where things got interesting.

Had to work through getting the YUN on the network of choice.  Not a big deal but it took some time and many attempts to get it dialed in because the Arduino instructions tell you to go to arduino.local to find the individual unit.  Well this only works about 60% of the time.  So the solution is to use the IP address of 192.168.24.1 now I could configure the thing to my liking.  Once configured it would not show up in the Arduino IDE at all.  Major issue for me as I had no idea if the unit configured or not.  I finally when on to my wireless router to see if the board was being recognized.  Had to dig out all the USER ID and PASSWORD info and then work through all the menus to determine what in fact was connected to the router.  There is was — YEA

Now I had to research out why it was not listed as a port option in my Arduino IDE.  Well after some time and deep research I found that Arduino IDE only works some times for the YUN on wireless.  So the uploading from Arudino IDE to the board is not an option as most of the YouTube videos demonstrate quite well.  This becomes an issue because I found out that as configured the YUN does not have enough on board memory, so a SD card is needed.

Using an SD card with the YUN requires that the card be format using the YUN.  To do that you need to know that the YUN is connected to the internet and working properly which is very hard to know if it is or not.

So once you know the YUN is connected and you have it connected through cable to your computer you need a file called ” YunDiskSpaceExpander” found on the Arduino site.  Once uploaded you access it through the Serial Monitor of the Arduino IDE.  If all goes well you answer a bunch of cryptic questions and bingo the thing kicks off.  Once do you have a formated YUN SD enabled board.

Now I am ready for the real fun stuff to generate code to be used through Temboo so I will have “Streaming Data” and text messaging in short order – lets hope!

The good news in all of this is that I will be documenting all of this for the instructions to the Balcony unit for all to use and save anyone interested in building one or gets a kit from me that will be up and running in short order.

See you all at Maker Faire next Saturday if you make it there!

aquaponic-IoT device — Balcony Garden

BALCONY AQUAPONIC GARDEN – IoT READY- DIY  or purchase materials locally and build —  by rik kretzinger

With all the interest around the world in aquaponics there are a number of creative units being developed for small spaces.  Many if not most of these solution do not address a number of issues that cause these units to end up on Craig’s List or in the trash at the end of the day. None of these solutions even address the automation aspect of aquaponics to take the stress out of operating a small unit effectively at an affordable price point and can be assembled safely by anyone interested in aquaponics.
 
AUTOMATION COMPONENTS:
1 – DHT-22 – Humidity and Temperature
2 – DS18B20 – 1 wire Temperature probes  (grow-bed and fish tank)
1 – Analog Float Switch in Fish Tank for water level tracking
1 – Analog Water Sensing Probe in grow bed for tracking water level and timing of cycles
4 – Relay Controlled outlets
1 – Master System Kill Relay – should anything go wrong with the unit
1 – Stainless Steel gravity feed Valve N/O – allows for precise control of cycle times and water level control in grow bed,
 
BALCONY GARDEN KIT FEATURE SET:
27 gallon fish tank
27 gallon grow bed – this allows for the aquaponic standard of 1:1 ratio of water to grow bed volumes be maintained for a healthy system
DIY Solids Filtration unit – allows for solid wast capture or removal and reuse in system
DIY Bio-Filter reactor – converts toxic fish waste to non-toxic plant fertilizer using moving bed media (big system component not found in any small systems)
Overflow Preventer – will not let any water to escape from your grow bed should you encounter a system problem
Root Clogging Preventer Mechanism  –  this is the problem no one talks about in aquaponics – roots clog everything – unless you plan for the problem
System power down – should a power failure occur
Air supply back-up for fish tank – should power failure occur
Plug-N-Play construction of kit
Once assembled and cycled easy to maintain.
Starter water – bacteria rich and ready to jump-start your system provided with the kit
Small footprint – big results
High percentage of materials can be locally sourced at a big box store and rest at Amazon if you want to do-it-yourself (DIY)
System allows for a high degree of control of the flood and drain cycles depending on what you are growing and environmental demands
Allows for expansion of sensor set and moving to solar back-up option in the future
Unit can be converted to off-grid applications easily – will require a different power configuration of components and equipment
Starting code for system on which ever micro-controller platform a person would like to use

I have been reading about this product now for a while and finally thanks to J.C. Naumowicz got the link to check it out.

arduberry

Here is the link:

https://www.kickstarter.com/projects/john-cole/arduberry-unite-raspberry-pi-and-arduino?ref=email

This solution takes care of a number of issues that are hard to solve with arduino or raspberry pi on there own.  The two together are truly better together  than as individual solutions.

Enjoy and support this effort if it is something you think will be a better solution for us all.

Well it has been a while since my last post.  For good reason.  I wanted to hold off posting for some big accomplishments to talk about and set up the direction I will be going with this blog into the future.

FIRST BIG ACHIEVEMENT:

This will be my 100th post.  When I started this blog it was more an effort to explore ideas and concepts related to one small aspect of aquaponics and has now grown into a world wide effort from a number of neat people.

SECOND ACHIEVEMENT:

Have had my highest ever number of views on the blog and daily traffic has hit all time highs.

THIRD ACHIEVEMENT:

Will go over 50K view of the Internet-of-Farming this week!

IoT- Farming stat

LAST MAJOR ACCOMPLISHMENT IS:

Finishing of my    agponicMD (micro device).  I now have a fully functional aquaponic device that will allow me to test any and all scenarios that I want to.  This is a major big deal for me.   This allows me to actually achieve IoT on a personal level and be one of the first to reach a practical application that will help interest others in this area of farming and agriculture.  Without this blog and the comments from all you I would not have been able to get this far or learned so much.

First question is what is a “SLIDE SWITCH”?  Well they are very common.  Never thought I would need to know how they worked and how I was going to connected them up.  As it turns out I have two projects now that require them.  So now is the time to work out how to connect them up.

Here is what one looks like.  They are found in many electronic devices.

Slide Switch - blog2

Yet again in electronics you need to know what it is that you want.  There is not just on size fits all when it comes to “SLIDE SWITCHES”.  I thought this was going to be easy to get connected up.

Here are just a few of the options I had and decisions I had to make on such a small part.

SPDT – Single pole double throw

DPDT – Double pole double throw

SPST – Single pole single throw

SPDT Sub-mini

Heavy Duty Slide Switch

DPDT Right-Angle PCB Mount

These are just the options at Radio Shack.  Do an internet search and the options are endless (seems like).

To solve my problem I made a trip to Radio Shack and made a purchase to get started.

6-pack slide switch

Once I got them home I had to deal with picking between the option of 2-3-4-6 prongs to work with.  To solve this issue pulled out my multimeter and tested my options.

The end result I was after is to be able to  switch between external power and arduino power (parasite power) for my sensors.  The reason for this is some times I want to run external power, but when I am only testing a few sensors I just want to keep things simple and run off  arduino power.

The end result was use a DPDT Slide Switch. This required to use the 6 prong switch.

4 – completed connectors and fully tested

The next step to achieving running 20 probes was to complete the 4.7K resistor harness set-up.  I now have this done and can move on to the finishing off the ground connector that will allow pull all this together.

I learned a few weeks ago that I was selected to present at the World Wide Aquaponics Conference September 21 to 23 of this year.  Here are the details if interested:

Aquaponics & Arduino —  The WHAT – The HOW — and into the FUTURE – In this workshop attendee’s will gain a understand of the arduino platform and how custom aquaponic automated solutions can be build on any scale.

Workshop OBJECTIVES:

–  Know what an arduino is
–  Understand the concept of open source
–  Touch and feel the sensors that are used in a aquaponic system
–  Demystify the use of technology in aquaponics
–  Gain understanding of what the future in aquaponics can and will look like
Rik will have a full working desktop unit that is fully automated on a DIY scale. We will breakdown each sensor and explore how they work.  We will talk about available resources and see how items purchased on a local level can lead to an automated system that is easy to install at any level.  We will have web references and instruction guides on all the major components and how they are connected to form a “SENSOR NETWORK” in today’s world.  We will talk about and demonstrate the concept of “INTO THE FUTURE – EVERYTHING WILL HAVE AN IP ADDRESS”
