HyperPhysics – Educational Resource Physics Electronics

HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or “cards”, true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network..

Electronics Concepts at HyperPhysics

Students should go thru this website from cover-to-cover, It is a work of knowledge that is priceless

Ampere Law at HyperPhysics

Ampere’s Law at HyperPhysics

“Ampere’s Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.”

Astable Multivibrator with 555

This is a demo of the popular 555 timer. you can try out the project on this page by a javascript simulation.Press the Red button below to turn on the circuit press it again to turn off. The 555 can source (LED2) or Sink (LED1) upto 200mA.

This is a tutorial with calculator to help learn the application of 555 which is a very rare chip innovation. It is simple, versatile, flexible and programmable (by tweaking of pots).

Measurement Basics at National Instruments

For an T&M Learning, Start with these tutors of NI. Like Analog Amplifier Circuits and Analog RC Filters. RF and Microwave Fundamentals if you want to be good at Communication Technologies. Sensor, DAQ and Instrument Fundamentals for Industrial Automation Learning.

Measurement Fundamentals – National Instruments

National Instruments Wi-Fi DAQ devices combine IEEE 802.11 wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI LabVIEW software for remote monitoring and control of electrical, physical, mechanical, and acoustical signals.

Measurement Basics at National Instruments

NI Wi-Fi DAQ features and to learn how you can simplify wireless remote measurements without compromising on the security or performance of a cabled data acquisition solution.

delabs Notes

You can learn about every niche/domain in Electronic Technologies. You also need to Specialize in a niche which resonates within you. The skill sets need to be broad, in case you find less opportunities in the specialization you have. This keeps changing all the time.

Non-Destructive Testing NDT Resource

Eddy Current Testing (ET) and Infrared/Thermal Testing (IRT) are Interesting Areas where experienced designers can build and manufacture Test Equipment.

Community College Education Resource

These pages have NDT study material for college and Science Educational Pages for High School.

Students can get ideas for original project work on one of these concepts. Choose one area and then research in the web. When i had to build Equipment, it would be difficult to get the catalogs and datasheets of Materials or Methods. Now master the art or searching online, then create your database. Study, Learn and Build !

Direct Read Pocket Dosimeter

Pocket Dosimeter

“Pocket dosimeters are used to provide the wearer with an immediate reading of his or her exposure to x-rays and gamma rays. As the name implies, they are commonly worn in the pocket. The two types commonly used in industrial radiography are the Direct Read Pocket Dosimeter and the Digital Electronic Dosimeter.”

“An extensive series of pages based on experiments that can be done in the personal or home laboratory. The emphasis is on enjoyment and intellectual pleasure, but there is much practical matter as well.”

Electronics Index – Includes vacuum tubes and cathode-ray tubes, with many experiments for the home laboratory. Nixie clocks too.

The Atmel AVR microprocessors are very similar functionally to the PIC microprocessors, with the same range in size from 8-bit, 8-pin PDIP to 32-bit processors with 100 pins, and similar features.

Atmel AVR 8-Bit Microcontrollers

Atmel AVR 8-Bit Microcontrollers

The ATtiny13A will operate from a supply voltage as low as 1.8V (maximum clock speed 4 Mhz), and with a full 20 MHz clock speed at 4.5V and above. The current drain is much reduced at the lower supply voltages and clock frequencies.

A Magnetometer

It is easy to measure moderate magnetic fields using a Hall sensor, such as the Allegro A1302 linear Hall sensor, available from Jameco. A PIC12F675 can digitize the output of the sensor and display it on a serial LCD display, such as the Newhaven NHD-0216K3Z-FL-GBW 2 line x 16 digit display. This system is shown breadboarded in the figure at the right, measuring the field between the poles of a horseshoe magnet.
