Electronics WebLinks


Electronics Engineering and Technologies


The internet is interconnected by links, In the early day of the web, most webmasters would create a Resource page and sometimes a category based links directory. Then they recorded all the useful resources and sites they came across.

Giving credit, attributing the creator for his work was a worthy tradition. This resulted in useful inline links, the editor of a page or article even gave references to many other useful related pages.

Engineering and Technologies

These actions created a high quality network of websites, which even the search engine spiders used to crawl, to provide search results of high relevance and quality to the visitors in those days.

These pages of mine and other sections of delabs, follow that old tradition and lists thousands of firms and EE design resources around the globe, related to Professional and Hobby Electronics. This work of mine started in 1999 on netscape, geocities and tripod homepages. Now it is distributed over few domains and tech blogs that i own and manage.

Some Electrical and Mechanical pages closely related to Electronic Manufacturing and Industrial Engineering are also listed here.

delabs lists more than 10K EE Companies & Resources in the Web. Support by Advertising in delabs

Materials and Equipment

Looking for a Tech firm, a component or a tool, i may have some listed here from my ee experience.

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 gadgets 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.   DC Regulated Power Supply

Applications and Components

The basic building blocks for most circuits are Chips or ICs. You can acquire considerable knowledge by studying Application notes of National Semiconductor and Texas 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 - eg. IR and RF Components have to be understood well, in order to design sturdy Industrial Grade Designs like ST Micro.

(National Semiconductor now part of Texas Instruments. 2011-12)





Advanced Engineering

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 factors. 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 solutions.

Industrial Automation and Process ControlTacho Counter

Automation and Control is the predecessor of Robotics and Mechatronics. A Jump Start, Practical and standard reference for Process Control is at at Omega Technical Reference.

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 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 Networked Systems.

About delabs

delabs maintains an Electronics Circuits Archive with some Technical Documents, many of these 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 Professionals 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. delabs created content and circuits, can only be used for product design, product development, study or hobby.

Tera Ohm MeterThe delabs name is for the websites and content managed by me. My experience is in the design of custom industrial and instrumentation products. delabs plans to be a web-service for product design and development. I like to work on projects 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.
