    Android WebView App (to Apache server)

    Yippyyyy!!! Just successfully created my first Android App. So I have been playing around recently with modifications, improvements and configurations on my current project - "Smart Home using Raspberry Pi & Android with Voice Recognition." I have been thinking of implementing a simple Android application which directly opens up URL, rather than going to my browser each and every time I need to access the web control server(Apache2). So one... [Read More]

    Smart Doorbell using RPi with voice and email notification.

    Part of my project involves having a doorbell, I figured a simple doorbell whereby a visitor just presses a button and then it rings/ notify whoever is it the house, That's not really creative in my point of view. So I then decided why not have a doorbell that not only rings when the button is pressed but also tell you someone is at the door and then sends you... [Read More]

    RPi enabling I2C communication

    I have considered to use a combination of an Arduino Uno and RPi for my Home Automation Project. After vigorous research(Googling of cause) on how I am to interface the two, I came to a conclusion that using I2C was the best option as compared to using UART(which required Logic Level Switching as the RPi runs on 3V3 and Arduino on 5V), or as compared to USB communication. The idea... [Read More]

One... [Read More]

    Arduino Temp monitor : 16x2 LCD

    Phase 1:I have been procrastinating on creating a home automation system until I decided to dedicate a few of my hours to this project. I have decided to use an Arduino and a Raspberry Pi combination. The idea is to have the Arduino running all ADC calculations and sensors as the Pi is not equipped with an ADC, and use the Pi as logger and dashboard using apache2/graphite or something...

    Advice from an Old Programmer

    Very good read

    Memory - Card game

    I have been spending quite some time learning python for the past few months from text processing to game development using simplegui. And I must say for a person that always thought in C, I find Python completely straight forward and an easy but high level language. As my journey to Python continues, This weeks project was a memory game. Although it does have a couple of bugs in it,... [Read More]

    Install and configure NFS server on Ubuntu for serving files

    When it comes to serving media content within your local network, a NFS share is way better than Samba/CIFS share in terms of speed and resource usage. If you have a XBMC box to watch TV shows and movies from a central server then a Network File System (NFS) share should be the choice for a media source. It only takes a few minutes to install and configure NFS server... [Read More]

    script to generate BASH scripts
