When you wish to learn Electronics, first a short study of Physics
is essential, secondly some Electronics
theory. Then build simple and small gadgets to learn Practical
working with Educational
Lastly to make your own product designs, a fundamental knowledge of
and Digital Electronics is the foundation for your next steps into
Applications and Components
The basic building blocks for most circuits are Chips or ICs.
You can acquire considerable knowledge by studying Application notes of
Instruments, to start with. When you want to use a
Microprocessor or Build Microcontroller Projects, you can study the
documents at Atmel and Microchip
to begin. The Specifications and Behavior of Passive
Components like inductors, capacitors and Resistors; Discrete
Semiconductors; Power Devices -
and RF Components have to be understood
well, in order to design sturdy Industrial
like ST Micro.
The Technology related to the equipment used for Testing,
called Test & Measurement, Here we use Test Instruments like
Multimeters. Medical Electronics and Military Designs require more
meticulous, robust and dedicated designs with higher reliability and
accuracy. In Medical
safety is vital, Consumer products should be affordable without
compromising Human Safety factors. Then you need to look into Usability
which is a science
that helps us develop practical and cost-effective products, which have
an optimum Man-Machine Interface. EMI, ESD, RFI are other important
that deals with Electromagnetic, Electrostatic and RF; Noise
and Interference; in the Stable performance of products in Real World
Harsh Environments or the Reliable Transmission of data. Lastly
Computing and Communication makes products more versatile in any
application. EDA, Technical Computing and Systems Engineering helps
creating products and
complete process solutions.
|Industrial Automation and
Automation and Control is the predecessor of Robotics
Start, Practical and standard reference for Process Control is at at
Omega Technical Reference.
Control system is made of Sensors
sending acquired data to a Controller
which operates Actuators
to manage the
process in Real Time. Starting
from a Bimetal Thermostat to a SCADA, the controller
has grown from mechanical -- electrical -- analog -- digital devices to
microcontroller-computer based equipment.
Both in Control Systems and
the Collaboration between Robots or Control Units, leads to the
development of wireless network of Interactive, Intelligent and
Distributed Self Governing Systems. The outcome is Web Process
Automation, Web Applications based Solutions
Monitoring, Analyzing and Configuring these Sophisticated Networked
delabs maintains an
Electronics Circuits Archive with some Technical Documents, many of
circuits were designed or developed by me. There are also many
links to useful electronics, freeware and open source websites. The
intention to put it in the web is to enable Students, Hobbyists and
to get more ideas on various aspects of electronics and circuit
design. The Links Directory of delabs includes Companies, Service
Manuals, Datasheets and Application Notes.
The Technologies and
Hardware Configurations of delabs are Open Designs.

is for the
websites and content managed by me. My experience is in the design of
industrial and instrumentation products. delabs plans to be a
web-service for product design and development. I like to work on
related to Electronics and Internet.
The product shown on the left is a Insulation Tester and a Tera Ohm
Meter. It was the first product i designed many years ago. A DC
regulated Test bench Power supply, a later creation of mine
is shown above.
