On 21st January 2012, I went to Jalan Pasar to search for some components. However, most of the shops were closed due to Chinese New Year Celebration but I manage to get a few components as below. Meanwhile, for the rest of the components, I decided to order through Farnell. It is more convenient to order through Farnell because it has wide range of component selection and you can just ‘click’ to buy the component that you need from the comfort of your home.

  1. Assalamualaikum. This is my first comment to your blog.
    You have missed quite a few weeks of project reporting. Pls type in at least one posting a week no matter how little it is.
    I noticed that the image is quite slow to download. You may want to scale down the image pixels.
    Contents wise seems ok. Progress a bit behind. You need to be able to test your hardware soonest possible.
    Good job so far.
