One of the main reasons why the Raspberry Pi is so popular these days is because of the size. The Raspberry Pi is so powerful in its size that desktops were required to do those tasks some 10 years back. The small size gives portability to the Pi and that is what drives us to find new applications for it. The major factor in hindering the portability of the Pi is the power supply. Since the Pi is driven by a 5V supply which is obtained from USB chargers connected to mains, the Pi cannot be truly mobile. In order to take it mobile, people are using it with Power banks and batteries. There are few people on the Internet who have posted the current drawn by the Pi under different circumstances and which could be helpful but it doesn’t give an estimate of how much a Pi will run on a particular batteries with a particular project. In this post I will try to compile the run time of Raspberry Pi running under different circumstances using Power Banks. Although I am an Electronics engineer but I don’t work on Electronics, so I will not concentrate on current drawn but rather run time in hours. Continue reading
With the introduction of Troubleshooting section in CCIE Lab Routing and Switching, getting the CCIE number has become ever so difficult. I have even come across people who have switched to other CCIEs like Security, Voice, etc because clearing Troubleshooting section was beyond them. The other problem with TS is that it is placed before the Lab exam, so if you think that you will not be able to clear TS Section, you will have absolutely no interest in completing the configuration portion. The disadvantage to this is that you will lose the free attempt to practice configuration section which would be helpful in future attempts.
In this blog I will write about the Non-Technical aspects which might help you in clearing the TS Section. There are several things you must know before you attempt the TS Section, during the preparation for it, before attempting it and during the attempt. These inputs are based on my experience and could differ from people to people. Continue reading
