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..

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

It can even drive a small motor or lamp with diodes added to protect from inductive kickback.Vary Ra, Rb and Ct with the controls given and see the change of frequency, period and duty cycle.
Astable Multivibrator with 555
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).
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.
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.
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.
Melabs from Colorado Springs designs and markets embedded systems for Training and Prototype design. The include complete systems for PIC microcontroller development, Device programmers and Programming Adapters that support over 500 Microchip microcontrollers.

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 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.”

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
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.
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.
