Flying to Dubai from Düsseldorf: Travelogging

It is a great evening! Clean home, great food, soo much love from friends. Most of all the messages coming in hot with a lot of good will. So confident about the next 10 days of air travel and spotlight events. It already started out the previous night with my sponsor saying that they are also provide to have me with them.

Thanks to Laura and my awesome twins didn’t feel weird about the airport lone time! Thinking about it while sitting alone writing this was nice. Continue reading “Flying to Dubai from Düsseldorf: Travelogging” →

TI CC2530DK – Contiki OS – Internet of Things

This blog post is an effort to create a one stop information for starting off your Contiki project with cc2530DK.

There is enough information already available on Github wiki. This post is more than an extension to have all information under one place and as usual my way of documenting my projects!

WiFi Positioning System – Using Python and Google Geolocation API

I consider there is these following steps involved for such a program.

I will keep this as a documentation as well as a progress report to keep track of the project.

  1. Reading all the required information
    1. Reading SSID in MAC
      • Using Airport Shell command
      • Here is how it should look: [viraldownloader id=180]
    2. Reading SSID in Linux (Ubuntu), Windows
      • identify shell command for linux/Ubuntu
      • identify shell command for windows
  2. Parsing them in JSON format
    1. Parsing information into required information into prescribed format
  3. CURL and Get the Location information in JSON
  4. Parse it and display on google
  5. Building a GUI

Here is the gitHub repository for the project that I am working on.

My endeavour towards creating cheap backup space

I started good with a 512GB HDD and a Dell Studio with a 512GB HDD in 2009.
I was never out of space until 2013 when I bought my new MacBook Air with 256GD HDD. I would describe it as a glorious decision but totally not happy with the 46GB free space!
Since then I m trying to find out a best way to create more storage space and I am going away from the idea of using a physical device since I like to go mobile and light. I want it to be accessible all the time i.e. even without carrying my storage device. Continue reading “My endeavour towards creating cheap backup space” →

Did I know: A water fountain could produce 1,33,303 ?

I always think how much this setup could pump out?

This is a fountain at Technical University of Dortmund.

Too much in to thinking and I was spoiled by my Statistics for Reaseachers and Engineers (SRE) course!

It made me think, why not compute.

What I found is about potatoes that can be grown out that fountain running through the summer was interesting.

This was more of an academic endeavour for me.

I made a test by conducting a trail for measuring the water flow through it!

Now why not use R project for the purpose of computing?

I know its a lame for using such a powerful tool for a simple math but its not bad for getting around R!

some of the assumptions made:

Diameter of the pipe = 1 cm
flow rate is constant for 6 months

if someone is able to measure it > comment in the post!

Formula used:

http://www.1728.org/flowrate.gif
formula used from www.1728.org will be implemented in R Code

Formula in R

pipeDiameter = sqrt (4 * flow / pi * velocity)
velocity = (4*flow) / (pi * pipeDiameter^2)
flow = 1/4*pi*(pipeDiameter)^2*velocity

A bottle was filled in 21 seconds. Winny was the time keeper. It was a 1 litre bottle. So scientifically saying it took 21 seconds for 1000 millilitres. (Please comment if you have more accurate results to take a list of values from different trails to make the calculations more robust)

> flow = 1000 /21
> flow
[1] 0.04761905 # litres / second

The above data was to get the facts straight and may be I would use it later. Since flow rate is assumed to be constant for 6 months which is the period the fountain is in service. I want the time to be six months since it is only on during the summer and during the winter it is going to be frozen!

Let me try to find out how much water is being pumped out during the service period in the next page.

Hello world!

Welcome to my blog.

I am writing to document my findings and experiences in various projects.

It may not be informational, it may not be commercial but it is for a personal satisfaction!

This took a long time to set up the WordPress website and I had to contact the host to figure out some of the compatibility issues.
