Building a DIY 5.1 Audio Video Receiver – Part 6
In the last post I mentioned that I was looking for a crossover board. The one that I purchased is putting out a huge DC bias and I was not comfortable using it on my sub woofer. Wondering if it is a problem with the particular unit that I got, I ordered a replacement. Unfortunately, even the replacement has the same signature output. So I decided to do something about it myself.

Managing Dry Waste - Part I
I have been composting my wet waste for a while now (roughly 3 years). The yield of the compost has been good and it has become an integral part of the kitchen. Lots of valuable plants have come out of it and it's been a worthwhile experience for me. I cannot say the same about our dry waste though. Our layout has a BBMP trash van that collects wet and dry waste. I stopped giving wet waste since I have been composting all of the wet waste. However, I have been religiously giving them my dry waste.

Building a DIY 5.1 Audio Video Receiver – Part 5
So far I have finished bringing up 4 of my 5.1 speakers in my DIY 5.1 AVR project. If you missed, check out part 1, part 2, part 3 and part 4 of the series. Next I wanted to bring up my sub-woofer. Since I have an active sub-woofer, I did not need any amplifiers to drive it. I just need to connect the output signal from my audio source directly to the sub-woofer input. But there is a catch. If you connect the audio source directly to the sub-woofer, the sub would be wasting a lot of energy which may heat up the driver and may damage it. Moreover driving the sub with all the frequencies will give boomy muddled up sound. So we need a low pass filter or a crossover.

Franklin Saga Drags On
Franklin has been in the news quite a bit due to the decision to wind-up six of its funds. After deciding to wind-up the funds the fund house was planning to get unit holder's consent for disbursing cash from liquidated papers. However, some investors did not like the decision and started legal proceedings against the fund house. Unit holders filed cases in multiple High Courts. Now we all know how long courts take to pass judgement on just one case. Given there were multiple cases I was not very positive that something will happen any time soon.

Different Types of Investors
Let me start off with a story. So the other day a friend of mine called me up asking me to help him solve a plumbing problem. He probably thought I was good at plumbing because I have been working on rain water harvesting and drip irrigation. Anyway, he tells me that there is a tap that was constantly leaking water. He tightened it fully, but the water still leaks. Asks me if I have a fix for his problem.

Building a DIY 5.1 Audio Video Receiver – Part 4
As I mentioned in my last post, after measuring the frequency response and testing the TDA 7498, I decided to buy one more. The board I bought earlier did not have the right LC filter for a 6 ohms speaker. It was designed for 8 ohms speaker. So I decided to use that board for my rear surround speakers which were also 6 ohms. However, it is fine to have a slightly poor quality amp for the rarely used rear speakers.

Investing For Multiple Goals And Portfolios Management
One of the readers of my blog asked me how I manage multiple portfolios for various goals. They also wanted to know what platform I use to manage portfolios for family. So I thought I will expand a bit on that topic. To start off, I don't have multiple goals. I just had and still have retirement corpus as the only goal. The portfolios I manage for my parents, wife and kid have only one goal as well. However, mine is a unique case and almost everyone have multiple goals. As I mentioned before, every goal needs to have a different portfolio.

Building a DIY 5.1 Audio Video Receiver – Part 3
The TDA7498 class D amplifier board that I purchased to power my front speakers was working great. The audio quality is at par with what my Pioneer 5.1 AVR delivered using class AB amplifier. I could not tell the difference in audio quality. None the less, I wanted to make sure the quality is really as good as my ears led me to believe. Enter a function generator and oscilloscope to make sure the frequency response is satisfactory over the range of audible frequencies (20 Hz to 20 kHz).

What Is Your Net Worth And Is It Good Enough?
Sometimes it is worth knowing if your net worth is good enough or not. But how do you know if it good? And what if you don't even know how to calculate your net worth? These are some of the questions I am trying to address in this post. Simply put net worth is the sum of all your assets minus the sum of all your liabilities.
