Basic Requirements for Raspberry Pi

Once you got your hands with a Raspberry Pi model B, the first thing you have to do is to make sure you have all the things that you want to use. In my case of making an advertisement/notice panel, the requirements are as follows

What you'll need
  1. SD Card - I recommend an 8GB class 4 SD card
  2. Display & connectivity cable - Any HDMI/DVI monitor and any TV should work as a display for the Pi. (You'll need a HDMI-DVI converter if you're using DVI)
  3. Keyboard and mouse - Any standard USB keyboard and mouse will work with your Raspberry Pi. (Pre-paired keyboard and mouse can also be used)
  4. Power supply 
    • The Pi is powered by a USB Micro power supply (like most standard mobile phone chargers) 
    • You'll need a good-quality power supply that can supply at least 700mA at 5V. 
    • Low ampage (~700mA) power supplies will work for basic usage, but are likely to cause the Pi to reboot if it draws too much power.
  5. Something for the Network
    • Ethernet (network) cable - An Ethernet cable is used to connect your Pi to a local network and the internet - OR - 
    • USB wireless dongle - Alternatively, you can connect to a wireless network using a USB wireless dongle, which will require configuration.
  6. Speakers are needed if you're not using HDMI connection.
If you have all of the above, you can start the Operating Systems installation.

Advertisement News Panel TV (Part 2)

... continued from previous post.

The solution for my previous problem comes in a size of a credit card. It is a small computer called Raspberry Pi (RPi or Pi). I've never played with the gadget before, however knowing that it can run a Linux, I'm pretty sure by giving some time and effort, it can run everything I desire.

Raspberry Pi model B.

So I purchased one online. Purchasing a RPi is quite tricky. If you're from an institution or company, you can buy it directly from element 14 (official international main delaer). If you're buying as an individual, you need to find a dealer. Finding a dealer is quite difficult, but I finally got one via online store. 

Once received, I immediately hook it up to my living room TV with HDMI, plug in the wired LAN, keyboard and mouse and voila, it is up and running the installer in no time. I installed several OS onto it to find the best solution for my requirements.

Tested for several days and by looking to the need, I uninstalled all other OS and just stick with Raspbian (Raspberry Pi + Debian) Linux. It works like a charm. I'll write more about the settings in the future. 

Advertisement News Panel TV (Part 1)

Several of my colleague and I were selected during a meeting to jubilate my office building. We were asked to make the office more employee friendly, and at the same time encouraging them to be happy to come to work. 

"Team Keceriaan" was formed. Like any decoration team would do, we decided to put some plants inside the building, some paintings, etc. Same ol same ol... Then I came in and suggested to buy new TV, a PS4 and many many gadgets for the faculty.

Ideas came pouring about making an advertisement LCD panel. I checked Chromecast, Apple TV and all sorts. It was not suitable because it won't be as secure as we wanted it to be. Then I started to ask around. I looked at the library and asked them about their ad TV system and all. 

Their system costed a lot. RM10000 (USD3000) for the software, and RM800 (USD270) for each computer behind the TV. I just keep their system in view.

Then we got some bad news. The budget being cut! Now the system that the library used is out of the question. So I have to find a way to cut the price. Or else, we would need to cancel the advertisement news panel TV altogether. 

I've found a solution... I'll update about it later in my next post.
