The Electronics Index of J. B. Calvert

Many may already know about these EE Educational pages with Circuits of J. B. Calvert.  These pages are valuable as they are like a summation of Important and Practical Sections in many EE Subjects. If you want to master the basics of EE, these pages will propel you in the right direction.

A Welath of Information is at the site - Dr James B. Calvert Associate Professor Emeritus of Engineering, University of Denver and Registered Professional Engineer, State of Colorado. An EE-Encyclopedia Almost.

Engineering and Technology - James B. Calvert
"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 Electronics Index of J. B. Calvert

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.

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.
