Theory must be studied once and referred to, again and again as you do practicals. One is by building DIY projects and then modifying them. Also Repair of equipment, troubleshooting, testing and calibrating. Then you know how components behave and real life limitations. Now design and engineer a product and test it at customer site. do a pilot production and test with more clients. Now you will learn to think based on practical applications.
This invention lead to modern electronics, computers and internet look at this page, Transistor Photo.
A picture of the first transistor ever assembled, invented in Bell Labs in 1947. It was called a point contact transistor because amplification or transistor action occurred when two pointed metal contacts were pressed onto the surface of the semiconductor material.
The digital circuits section has been updated, most are in the pdf format. Broken links removed or changed..
Digital Circuits - These circuits are based on CD40xx Chips and other. You can use 74HCT or any other series that is available. use one family for a particular project. These were used nearly two decades ago. Use it for learning, glue logic or to interface your uC designs to external devices.
Do not make only Logic based designs like some below. It would be better to use a uC, CPLD or FPGA if you are building a complex gadget Basic Digital Circuits
The EE Resource Sites has been updated. These lists are now over a decade old. Many Broken Links have been removed. Some Resources that were listed have moved to the blogs.

Electronics 1 - Hobby or DIY Electronics and Electronic Engineering Design.
Electronics Hobby or DIY Electronics and Electronic Engineering Design go hand in hand. Many inventions, discoveries and improvements in this technology has been done by Non-Engineers who acquired skills and built firms that created many positions for engineers to work in....
Ham Radio Enthusiasts improved the Communication Awareness and Science of RF Circuits. Now Communication Systems are built on Embedded Systems. In every niche of electronics, Microcontrollers, SoC and DSPs have become indispensable.
Understanding the behavior of Electronic Components. Learning the usage of Mechanical Tools and Equipment to build or manufacture Electronic Products or Prototypes. Mastering the use of the Test Bench and Test Instruments like the Scope and DMM. All these constitute the total skill set in electronics.
Power Supplies, Inverters, UPS, Chargers, Electro Plating, Precision Welding-erosion, Coating Metals and many other Processes are made of high current circuits. Even in measurement of parameters like Micro-Ohm high currents are
involved. Electronic Circuits are required in such products to give
control to time, current, frequency and voltage in order to accomplish
with the required precision a process or job.
In any power equipment, efficiency and reduction of bulk is crucial so SMPS and high frequency control is an important part of this domain. These products also generate EMI-RFI. Product Safety Study is also vital.
Basic Power Supply Designs - AC and DC voltage Regulators, Battery Backup Power Supplies. Battery Chargers, UPS and Inverters. Dual regulated Power Supplies. 5V and 12V Regulators. Benchtop Power Supplies.
Switching Supplies and SMPS - Circuits of SMPS, Power Supply, Switch Mode Power Supply are here. High Voltage Power Supply concept. DC Regulated 3 Pin Power Supplies like 7812 and 7805. Workbench Supplies.
Here are many Types of SSR or Solid State Relays. In this section you will find SSR designs and PCB layouts which you can study. These were made and sold by me years ago. So the PCB layouts have gone thru some revisions and they worked quite well.
delabs circuits has been made Responsive. Tablet Computers, Laptops, Netbooks, Notebooks and Desktops will render most of delabs and dapj blogs/sites correctly. Other Devices like Smartphone and SmartTV are partially supported.
All blogs and sites of delabs are now SSL it looks like https://. That means more Security and Privacy. We have also removed most of third party scripts and social media links for the same reason.
These will be no New Year Card for 2021. Please Reuse the one below. Wish all of you a Safe and Sensible 2021. Give importance to Nature, Environment, The Flora and Fauna.
Protect and Preserve, Renovate, Revive and Resurrect Hills, Mountains, Lakes, Ponds, Rivers and Streams. If these deteriorate then the end of Mankind is certain.
Happy New Twenty Fifteen
Welcome an Era of new ways of Embedded Systems in Device Communication and Interface.
