Rolling Ball Machine Construction
After building a doll house and disk drop board, my daughter had another idea for a cardboard project. This time she wanted to build a rolling ball machine. Again, as usual, I comply. I had no idea of what she had in mind. So I asked her to do a drawing and explain how the machine is supposed to work. She drew a spiral on paper, cut it out along the pencil drawing. Then, pointing at the dangling spiral, she said "that is what I want".

Building A Disk Drop Game Board
In one of my previous posts, I was left wondering if toys have a place in unschooling. The argument was that the toys help develop creativity in the kid. On the other hand, why should we buy any toys if the kid is creative? They can build their own toys with nature. Well, I got a mild taste of the latter when my daughter proposed and help build a disk drop game board. For those unaware of a disk drop game, here is a picture of it.

Drip Irrigation Control System v4.0 – Web Server
In the past, I explained the hardware and software parts of the system. This concluding post on my drip irrigation control system will go into the details of the web server. As you know, I wanted to build a system that I can control from anywhere. In the previous designed, I had to be near the control system to configure the drip time and duration using buttons on the board.

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.

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 Arduino with ESP8266. The why and how follows.

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 :)

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 :)

Organic Gardening: Shade Net, Drips and Harvest 2.0
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 the rest of the terrace too. In the mean time, monsoon hit and the original shade net was all torn in many places, so it needed replacement. From that we understood that the shade net might need to be re-done every year after monsoon :). Eventually, after the monsoon we set down to work on the rest of the shade net project, dubbed 2.0 for obvious reasons :P

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.

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.
