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.
Here are the results:

This display was purchased to allow a graphical interface element to the automation effort of aquaponic systems. So I was very happy to find this display and it could easily be integrated into the overall design with a very small footprint.
ADAFRUIT is quite clear that that this 5″ HDMI display will not work without changes to the “config.txt” file to set-up for the different display size. In this case 800 X 480 resolution. The documentation to make these changes is very good and works as documented.
THAT IS UNTIL A NEW RELEASE OF RASPBERRY PI OS —
As always technology never stands still. Advances are made almost daily when it comes to Raspberry Pi and the OS is no exception. In late 2016 a new upgrade was rolled out called “JESSIE” with Pixel. There was a lot of buzz about this new upgrade and it does look and perform much better over all. Once you upgrade or update there is no going back.
The problem with the “JESSIE” upgrade is that now the solution provide by ADAFRUIT for the 5″ HDMI display no longer worked very well and was unusable as a display on the Balcony Gardens.
A fix was needed, but since “JESSIE” was so new no one was really aware of this resolution issue and the resolution issue was not even being talked about on ADAFRUIT site or in the Raspberry Pi forums.
After a lot of searching and months later a solution was found.
Long story so I will not go into details of the issue, but have documented it all in an Instructable that can be found here:
HERE IS THE FIX AND LINK TO THE SOLUTION:
Actual changes needed in the “config.txt” file for use:
In the file /boot/config.txt add the following text to the end of the file:
#increase HDMI signal strength
#remove black borders
#set specific CVT mode
hdmi_cvt 800 480 60 6 0 0 0
#set CVT as default
Save the config file and then do this: (see note below about this one)
sudo apt -get install xinput-calibrator
I have not tried using the above install command, because I was able to gain the results I needed without it. I believe like Auvy that sometimes less is more!
HERE IS THE LINK TO THE SOLUTION AS SHOWN ABOVE:

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 —
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!

Since first conceiving of the Tower unit as a concept I knew they needed to be operated differently than DWC and Media bed in how you deal with the solids from the fish. Media beds — it has not been that big a deal for me because my rule is that any tank size smaller than 350 I filter the water and break-up the solids and then put back into solution by pumping back into the grow beds. This way I lose no nutrients that the fish produce. Has worked well for over 3 years now. In the testing that I have done with the towers I found that solids need to be dealt with or things will plug up. I still will be reintroducing the broken up solids back into the system put it will take place downstream of the bio-filter component and re-injected into the new buffer tank that stabilizes fish tank water volume and height. This all came out of research I was doing on how best to handle solids in aquaponics. As designed this radial flow filter can handle up to and maybe a bit more than a 1000 gallons of fish tank water. The only thing left to figure out on this radial flow filter now is where I will be locating the outlet for the clean water. That will be dependent on fish tank water level. Should have fish tank completed this coming weekend and make the determination on this aspect of the build.
I put together a youtube slide show if you want to see more detail of the radial flow filter:

A lot of aquaponic systems use air pumps. So what is a aquaponic automation simulator without a air pump! Here is how it is handled and how it is connected up. This air pump comes standard on all the versions. The extra air line is for the planned 12V back-up configuration that is part of the pro version. Well underway on that unit and will have details soon.

Well I am into year 2 with my asparagus. The weather in Northern California has been short on rain and very warm. So no surprise that my asparagus is about 2 months ahead of normal. I was thinking that it would be about a month earl as I can control almost all the environmental factors that impact the growth cycle. Just so happy to see that it survived the winter and growing well. You judge for yourself!
