Near 2001 i started sharing my learning and experience in Electronics Engineering on Blogs and Newsletters. One of the Successful eMag and electronic email magazine ran for five years. I lost interest later in the email mag, and this magazine just morphed into a dozen or more Tech Blogs that run today.
This is an educative and important guide for Electrical Equipment Safety. This can be also applied partially to Power Electronics and Home Energy Systems. Electronic Equipment also have to be maintained by Calibrating them and protecting them from environmental parameters like dust, grime..

The very first designs that came about were analog designs, a Vacuum Tube amplifier is an example. Analog is the representation of data or physical parameter in an accurate and precise decimal number like +72.182 mV. The greater the resolution required, the more demanding is the design for achieving high accuracy and low drift. As an analogy, see the conventional water tap as an analog control, an electric light ON-OFF switch as a digital control.
There are many Serial Data Devices that means those that use the RS232 (old mouse port). USB is now the standard interface in most computers and embedded devices. Many mini embedded sensors and devices come with High Speed Serial Interfaces. This page lists solutions and methods to get These Devices talking with your computer. The focus will be HandHeld Computers made of the Android OS. This way you can get your hand on the Real World thru USB and Serial.
