Our company has setup a internal competition to create a CI Built Monitor to monitor the software check-ins. As it is for a competition inside the company, i may not be able to publicize much of the source code, but will still have some pics on the build… Read more…

Arduino Pet Feeder (Arduino Exhibit).

March 7, 2013 2 comments

My wife and I put together our pet feeder, for the Intro to Arduino event in Cape Town. We did the best we could with masking tape and cardboard, and put together a working prototype of an internet enabled pet feeder, with an online front-end.

The site, is still under development, but is functional right now [at] . The site is hosted on Google App Engine, written in Python. Once you log in, a profile will be created for you, and you will be able to set your time zone, as well as set 1 feeding schedule. Once that is setup, the Arduino will then be able to pull in that information over the internet. The site will be updated in the near future as well as the code for the Arduino made public, so you can build your own pet feeder, and use the site to schedule your feedings.

The yodafeeda was built using an Arduino, Ethernet Shield, cardboard box, hamster tubes, masking tape and alot of imagination.

I will post the pics of the feeder at a later stage. The exhibit demo went well and got the feeder to drop some food into a dog bowl.

Update: Exhibit went well.. I unfortunately didnt take any pics of the feeder… wasnt a looker as it was made of cardboard. Will need to work on the code a little more before I release it to GitHub so will keep you guys posted.

Concept: Arduino Pet Feeder

November 23, 2012 Leave a comment

I am going to build an Arduino pet feeder this weekend. Borrowed a servo from a buddy of mine, got my arduino + ethernet shield, a couple of plastic hamster tubes and a rubber ball to be used as my churning mechanism…

Still in the concept stage… but Arduino would run the EthernetServer, and keep track of all the schedule’s and timings on an SD card. I would also store all the webpages on the SD card to be served for client requests….

Samsung Smart TV Hack day

August 20, 2012 Leave a comment

We recently had a hack days project at work. One of the themes was using a samsung Smart TV. Our idea involved doing a home automation application. We used an Arduino with an Ethernet shield and relay, and hooked that up to a lamp. The web server on the Arduino would then listen for Get Requests passing a boolean value.

We developed the Smart TV app, and an Android based application dashboard to control the devices attached. This was a small proof of concept app, just to see what we would do.

Video of our demo can be seen here:

Ubuntu Unity

It has been a while since I did a post. I recently installed the Ubuntu Operating System ver 11.04.  I installed it as a partition on my portable hard drive so I could carry it around with me. I was looking for an OS specifically to install and run a development environment for my Arduino and other IDE’s to help with the debugging and creation of C code.

I originally tried using puppy linux, but this proved more difficult installing libraries and packages so I left that and moved onto Ubuntu. It come’s pre-installed with alot of applications and has an online applications repository. These include C/C++ IDE’s as well as the Arduino IDE. Will post some feedback once I get my internet up and running again and test it out.

C# App: Code For App

June 28, 2011 6 comments

I see there have been alot of visits to the C# app post, and as I am not able to upload the application to the site, I have now dumped all the code below.

You need to create a SerialPort object which will let you connect to your Arduino. You initialize it using the COM port the Arduino is using as well as setting the baud rate (The speed at which the Arduino will communicate). These are selectable via drop down’s on the form to make it easier to switch. You also attach an event handler to listen for serial data coming from the Arduino and to respond accordingly. The code was done in Visual Studio 2010, and is a fit for purpose quick code project. It does it’s job to just send and receive serial data.  Read more…

More components

June 10, 2011 1 comment

My wife surprised me recently with a few new additions to my electronics set. There have been a few components I was in the market to get and experiment with. These were the Ethernet shield, Wiichuck adapter and mechanical relay.


Ethernet Shield


The DFRduino Ethernet Board V2 (From

The shield I have is manufactured by DFRobotics called the “DFRduino Ethernet Shield V2” as an Ardunio Ethernet Shield clone. It has network capabilities and supports SD Card read/write. All official Arduino libraries work on this board.

Adding network capabilities to your existing Arduino comes at the expense of 4 digital pins (namely 10,11,12 and possibly 13) but is a small sacrifice if you can connect to the internet. This board also supports network connections up to 100Mb/s.

The shield stacks atop my Arduino Uno and feels like solid workmanship. The shield is compatible with the Uno, Dumlinove and Mega boards. Read more…

Arduino: Testing a Thermistor

Winter is upon us! And I thought to myself, its cold, but I do not know exactly just how cold it is. So I went online and found a

Tools for Thermistor test

Tools used for Thermistor Sketch

sketch (on the Arduino website) which experiments with a thermistor.

A thermistor  is a electronic component that registers a change in resistance in relation to the change in temperature. So the sketch requires:


  1. Arduino
  2. 10k resistor
  3. 10k Thermistor
  4. breadboard
  5. Jumper connectors. Read more…
