Vernier Software and Technology

They produces hardware and software for data collection in high school, middle school, and college science courses.

Vernier Software and Technology Balancer Project - Vernier Software and Technology

"Vernier co-founder, David Vernier, had been a high school physics and physical sciences teacher for eight years when he began programming his first Precision Timer software application. David's creativity and his passion for science education, combined with his wife Christine's business acumen, were the driving forces behind the early years of Vernier Software & Technology….."

Texas Instruments and Vernier

Shown on right is a Balancer robot that uses a Vernier Low-g Accelerometer to measure the tilt of a long beam. At the start, there are 10 gram weights on each side of the horizontal beam. As weights are added or removed, the beam unbalances and tilts.

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 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.

e-Learning Resources – Physics at Exeter

Excellent Online Educational Pages at Exeter. Students and Teachers can get ideas on how to enhance and enrich the Science Education Process.

e-Learning Resources - Physics at Exeter

A Sound understanding of Physics and Chemistry is needed for stepping into “Electricity and Magnetism”. We have to move young minds into Electronics even before High School, as a part of Science itself.

e-Learning Resources – Physics at Exeter
  • Practical Electronics II and Electronics for Measurement Systems
  • Feedback and Temperature Control
  • Computer Interfaces for Instrumentation Systems
  • Troubleshooting Op-Amp Circuits
Troubleshooting Op-Amp Circuits

The ability to diagnose and cure problems in a systematic manner is an exceptionally valuable skill. In PHY2028 students are given a heap of components, a breadboard, and measuring equipment.

Feedback and Temperature Control

System Model, Types of Feedback Control, On-Off Control, Proportional+Derivative Control, Proportional+Integral+Derivative Control, Proportional+Integral Control, Third-Order Systems..

ET - Technology Interface Journal

Technology Interface ia an on-line journal for the Engineering Technology profession serving education and industry. The Technology Interface has been developed to provide professionals in the Engineering Technology profession and related fields, the opportunity to share ideas concerning teaching, teaching improvements, projects, industrial activities, research and much more via the internet.

delabs Notes

An excellent study area for both Students and Teachers in the EE Domain. The important part of practical experimentation and industrial interaction is of great value to students.

A student can also on his own have a small lab in his house and start building and programming to supplement his academic training. You can build your lab from scratch, build your own test equipment. Start Somewhere. Build something and sharpen skills.
