|Electronics Product Design
When you wish to learn Electronics, first a short study of Physics
is essential, secondly some Electronics
theory. Then build simple and small electronic
projects to learn
Practical Electronics while working with Educational
Hobby Circuits. Lastly to make your own product
designs, a fundamental knowledge of Analog
and Digital Electronics is the foundation for your
next steps into Engineering a Design.
Applications and Components
The basic building blocks for most circuits are Chips
or ICs. You can acquire considerable knowledge by
notes. Then you would want to use a Microprocessor or
Projects. 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
The Technology related to the equipment used for Testing,
Troubleshooting and Calibration is called Test
& Measurement, Here we use Test Instruments like
Oscilloscopes and Digital
Multimeters. Medical Electronics and Military Designs
require more meticulous, robust and dedicated designs with
higher reliability and accuracy. In Medical
electronics product safety is vital, Consumer products
should be affordable without compromising Human Safety
Then you need to look into Usability or Ergonomics, 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 aspects 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
|Industrial Automation and
Automation and Control is the predecessor of Robotics and
A Control system is made of Sensors sending acquired data to
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 Robotics 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 in Monitoring, Analyzing
and Configuring these Sophisticated

delabs maintains an Electronics
Circuits Archive with some Technical
Documents, many of these circuits were designed or
developed by delabs. There are also many useful links to
electronic resources, products and companies. The intention
to put it in the web is to enable Students, Hobbyists and
Professionals to get more ideas on various aspects of
electronics and circuit design.
The Technologies and Hardware
Configurations of delabs are Open Designs. delabs
created content and circuits, can only be used for product
design, product development, study or hobby.
The delabs and dapj;
websites and blogs; are EE
Technology Publications. It has the resources for
custom industrial and instrumentation product design. delabs
is a service for product
design and development.
The product shown on the left is a Insulation Tester and a
Tera Ohm Meter. A DC regulated Test bench Power supply
is shown above. These were designed in the 80s and 90s.
