Working with the resistor module is making things much easier and a lot less work on my part. I am liking what I am seeing from a development standpoint and can see a real time savings that will deliver consistent results. First step is understanding what is found on the board and which end goes with which connection.
Been looking for a better way – DS18B20 October 15, 2019

I was doing some research on a totally different subject and this popped up.
Why this one?
Well easy answer – I have been making my own 4.7 pull-up resistor connectors for sometime now. Problem for me is that they take a lot of time and are very bulky and hard to work with. For a little more cost a dollar or so I get a board that will allow easy connections to many (so I think) DS18B20 sensors using one resistor. The order came and now I can start testing my idea. Having a solution this turn key will save a lot of time and perform better, time will tell now.
I will be posting how the testing goes and what will be needed to get top performance out of this module.
Miniature Test Leads – which ones work best for my projects July 20, 2019

I wanted to move away from alligator clips because they were much large when working with small gauge wire. They did not work for me in very small areas. So was looking for a better solution. Found this miniature test leads at Jameco Electronics when I was picking up an order, they were a good solution for me.
When first using these miniature test leads they worked very well. But after a little time using these leads and problems surfaced. The problem was that they were cheaply made. The connection of the wire and the metal insert probe would break off without much stress placed on them. One or two is understandable, but 5 out of 10 was not the experience I was looking for.
When doing a search for a new product on the Adafruit site I found these test leads
These leads are a little larger than the Jameco test leads, but still were small enough for my use. Construction and connections were of high quality and work perfectly and held up with repeated use. So these are my new go to test leads for my development efforts. They will be seen in a number of up coming Instructables that I am working on and all my testing of sensors and connectors.
WATER LEVEL INDICATOR – AQUAPONICS quest for a useful one September 13, 2018

THE PROBLEM IN AQUAPONICS for me —
Up to this point I have wanted to have a simple, but effective water level indicator sensor for the water level in the Balcony Garden fish tank component of the build – that works!
Aquaponic Sensor Set for Balcony Garden — see section on ultrasonic sensor
I spent a lot of time working with and trying to stabilize a ultrasonic solution.
First off these sensors are not waterproof ( the waterproof version is around $85.00 US Waterproof version). The non-waterproof versions run around $5.00 US. So this would seem the best way to go and work to make it work by using some waterproofing strategies. Hard to do when working in an aquaponic environment.
Next they are very hard to mount in a way that they can be useful to determining water level in a tank. There are a lot of instructables talking about this aspect for these sensors and even more youtube articles, but most if not all are just demos and breadboard applications. No real useful solutions that really can be implemented in a scalable way.
Final issue is that I have yet to be able to stabilize these sensors and have wasted a lot of time trying to get them to be reliable in a usable way.
SOLUTION – find a better method or be able to purchase one that actually gets the job done in a simple and affordable and scalable way.
Arduino IDE running on RPi using 5″ HDMI 800 X 480 display March 30, 2017

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:

I learned that Make Magazine vol 47 is now on-line.
So here is the link for review:
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.
