Circuit Design Service
Electronic Circuit and Product Design -
delabs can design the Electronic Circuit and PCB
if you have a Product Idea and Plan made.
If you need a circuit, product or a solution
designed as per your exact specifications, delabs
can help you with your Firm's EE Project or Idea.

delabs offers the following support and service.
delabs support includes circuit design and related
documents. PCB Design, Prototypes and Firmware
development is also done in some cases. delabs
does not undertake Consumer Electronic Projects.
- Product Feasibility study and Component
- Knowledge and Technical Information Support.
- Circuit and Product, design and development.
- Product Engineering and Testing Support.
Service Charges for documentation, email support
etc. will be charged depending on time and effort
Private Custom Design
delabs can Design or Develop, Custom Electronic
Products. Here the design IP - Intellectual
Property will be private. The design charges will
be more and the rights to that particular
configuration will belong to the serviced firm or
delabs works on Industrial, Instrumentation,
T&M and R&D Equipment Areas only. The
Product Prototype will be made by delabs with the
active support of the customer.
The terms for that will be sent by email on
request, after the Design Discussion.
delabs shall not accept projects or orders, that
may be in conflict with similar projects done
earlier for other firms.
Public Domain Design

|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
Applications and Components
The basic building blocks for most circuits are Chips or
ICs. You can acquire considerable knowledge by studying
Application notes. Then you would want to use a
Microprocessor or Build Microcontroller 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
|Industrial Automation and
Automation and Control is the predecessor of Robotics and
A 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
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 Networked

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
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.
