Drip Irrigation Control System v4.0 – Software

This is a continuation of my previous post on control system v4.0. In that post I wrote about the hardware. Now I will talk about the software. If you have been following my drip irrigation control system design, you know that I switched from Arduino to ESP8266. It took some time for me learn about the new board, but it is very similar to Arduino when it comes to programming it. Previously I used to use Arduino IDE, but lately I switched to Visual Studio Code with Platform IO plugin. This combination is quite powerful. Now I can configure build … Continue reading “Drip Irrigation Control System v4.0 – Software”

Drip Irrigation Control System v4.0 – Hardware

As promised, I started upgrading my drip irrigation control system with v4.0 design and software. If you read my last update on the control system, you know that there are two things that I wanted to add to it. One was a way to access the system via internet, so I don’t need to physically configure it. And the other was to add a humidity sensor. I finally worked on the first upgrade. Now my control system is accessible over the net (currently limited to my home network). However, I had to make a few hardware design changes. I replaced … Continue reading “Drip Irrigation Control System v4.0 – Hardware”

Investment Recommendation App I use

If you remember how I handled the market downturn and why I don’t follow the 70:30 allocation, you know the reason behind it. I was just doing what my app was recommending me to do based on the market. For the past few months I have been rewriting the app and finally have parity with the old version. This is one more of those pet projects of mine that I always wanted to work on after retirement and now living the dream 🙂 Background First some background regarding the app. I wrote a web app that gives me some indications … Continue reading “Investment Recommendation App I use”

Hundred Posts and Counting

I passed a wonderful milestone today. This is my 100th post on this blog. I did not realize that I was so close to this milestone. When I first started I did not have any intentions of doing it for the long term. It was supposed to be just an online dairy. I wanted to pen down my daily activities and thoughts so I can recollect the memories and rediscover the days gone by. But thanks to encouragement from friends and family it grew into a blog for helping others 🙂 In the last 100 posts I wrote on various … Continue reading “Hundred Posts and Counting”

Organic Gardening: Shade Net, Drips and Harvest 2.0

Some of you might be bored of the organic gardening posts, but I know at least a couple of people who are interested on the topic. Feel free to skip if you had enough 🙂 In one of the earlier posts, I talked about the shade net setup that we worked on in 2019. We only set the shade net on a small part of the terrace as a test and it worked brilliantly in protecting the plants. The rest of the plants outside of the shade net area were not handling the sun well. So we wanted to finish … Continue reading “Organic Gardening: Shade Net, Drips and Harvest 2.0”

Drip Irrigation Control System v2.0 and v3.0

In one of my previous post, I wrote about my drip irrigation control system. But there were a few problems with it. In the process of rectifying them, I built v2.0 and v3.0 control systems. And to think people were asking if I was getting bored in retirement or if I wanted to get back to work :). Why? I love what I do now and it occupies me completely. The first problem with v1.0 happened to be with the way it was designed. The drips starts as soon as the device is turned on. So if there is a … Continue reading “Drip Irrigation Control System v2.0 and v3.0”

Drip Irrigation Control System v1.0

If you have been reading about my organic terrace gardening project in the last few posts, you know that I have setup a drip irrigation system that automatically waters the plants everyday. Tinkering with electronics has always been my passion and this was one of those fun hobby projects that I wanted to do after retirement. Sorry, this post may be a bit too technical (electronics and code), so feel free to skip. I have a bunch of Arduino boards lying around and I thought I should use them to setup the automatic drip irrigation system. We needed 3 control … Continue reading “Drip Irrigation Control System v1.0”

Organic Gardening: The Harvest

I have been talking about my organic garden setup in the last two posts. So I thought it was time to show some results. The previous post ended with us setting up the shadenet around April 2019. From then on we have been harvesting some vegetable or the other. Although I don’t have photos for some of the harvest, what follows next are bunch of pictures of fruits and vegetables we plucked from the terrace as well as ground garden. Enjoy! April 2019 In April 2019 we got lots of chillis and capsicums. Not sure why. Perhaps it is the … Continue reading “Organic Gardening: The Harvest”

Organic Gardening: Shade Net Setup

In the last post I talked about how we started building our very basic organic terrace garden in the early spring of 2019. Soon the summer will start and we were worried if the plants will be able to handle the sun. Even during the spring season, the plants were having difficulty coping up with the heat on the terrace. So we decided to build a shade net. The idea was to Setup wooden pillars on all sides of the terrace Have wooden beams connecting the pillars Wrap GI wires around the beams to form a mesh Cover the GI … Continue reading “Organic Gardening: Shade Net Setup”

Organic Gardening: The Beginnings

Some time soon after I retired in July 2018, we decided to grow some organic vegetables in the small place that we have available around our house and also on the terrace. And ever since I have been planning to write a couple of posts about it. But somehow other important things came up and I kept on postponing it. Finally the time has come :). The project has been one of the longest on-going one. We still keep adding and changing things. We (my wife in particular) have been interested in home grown organic food for some time now. … Continue reading “Organic Gardening: The Beginnings”
