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:

Ever since the release of the “Internet of Farming” YouTube interview – the recurring question is how to get the code working on my Arduino for my situation. Well — the reality of it is that everyone has a very different situation and totally different conditions specific to their setup and needs.
In the video I was using what was the best solution at the time to overcome this programming issue for me and what I was working to accomplish. I spent a lot of time on research and internet searches and came up with the best solution at the time. Fast forward 3 years and factor in advancements in technology and now things have progressed at a fast rate and new tools and companies are popping up in this next big area of technology growth IoT – Internet of Things.
I started learning about Temboo ( https://temboo.com/ ) on different blogs that I follow and checked them out and began to learn more about their solution. It seemed very simple in concept and very close to what I was looking for to help others on the same journey I have been on for a long time now. Couple this with the Balcony Unit I have been developing over the last year for entry level people wanting a solution to learn Aquaponics and use automation — it was a clear match. It is a match because if someone built a Balcony Unit for themselves or purchased a kit of parts then they can customize the software solution for their needs using Temboo. All I would have to do is supply a base code to get people started and then they can take their Balcony Units ( or other projects you have ) to whatever level you want. There you go a PERFECT WORLD!
So as it goes I contacted Temboo about working with me on the Balcony Unit and the article for MAKE Magazine that is schedule to run sometime in the Fall of this year. Well it turns out Temboo was interested in this effort and will be working with me to get some base code build that all of you will have access to right here for the Balcony Unit. John Sigmier of Temboo reached out to me and let me know Temboo was interest in this effort. So I will be blogging about all this effort now that we are close to pulling it all together for the finished Balcony Unit effort. You will be reading about this effort and what I learn in this process.

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!
