Welcome to this post

 With patience and some videos from a famous video sharing center, you can repair almost anything, provided you have tools.

In the process you:

      1.  Keep your mind sharp;

      2.  You become process and quality oriented;

      3.  You have plenty of aha moments

Over the years, I have learned to trouble shoot:

     1.   car     2.  bike,    3. rice cooker   4.  electric fan.

By knowing how to repair and learning the inner working of machines, you learn how to take care of them better, and thus prolonging their service life.
