Hands-on learning(Help a newbie)

Former Member

     As mentioned, I'm completely a newbie to this field except for maybe blinking LEDs and stuff. This project I wish to do is not a school assignment. It is just a learning project I wish to do. I have        an idea in mind and would like your help to know whether it is feasible and if yes, how do i go about it.

 

     Project Aim: To create a system that turns off current to your mobile battery(Android {android.os.BatteryManager} ) if it reads a certain battery level. Any variations of this would be fine too. Like start charging if battery level < 20%.

 

    Any help would be much appreciated.Links to resources.Direct help pertaining to project as in components required, prerequisite knowledge required, expected challenges. Anything basically.

 

      I'm new to this community as well. Hope to make some friends along the way. Thank you.

    Hello Hasmit,

     

    considering that you have few knowledge in electronics etc, I suggest two ways:

     

    1) If you have a small budget, it is the worth to invest in a Raspberry PI 2 and a small bluetooth USB key (cheap ones works perfectly for about 5$)

     

    2) If you have less budget, I suggest to adopt an Arduino board.

     

    Then take in account the following two ways implies two slight different approaches, so it also depends on what is your preferred orientation (i.e. from where you prefer to start studying). Common to any choice I suppose you have considered that a part of Android software should be developed.

     

    In the case 1) you can be more software-like, involving hardware and Linux on a very good, fast and reliable platform. You can work with Python on the Raspberry PI and few linux settings we can help without difficulties.

     

    In the case 2) you should consider more hardware and a reduced software environment as with the Arduino or - better - chipkit micro controllers you have not a real operating system. This implies limitations and some more effort to reach the same results.

     

    Anyway considering all the aspect of the project, I think at the end of te work your budget is almost the same, and supposing that you already have the Android device, take in account to invest at least 60$. The more is your budget, better and sophisticated your controller can be. But the mentioned expenses is the very minimal cost you should provide.
