Paul Falstad EE Applets and Tablet Apps

"These are some educational java applets I wrote to help visualize various concepts in math, physics, and engineering." - Paul Falstad - (now with HTML5 and Canvas)

Electronic Educational Applets - Paul Falstad
  • Math and Physics Applets - MyPhysicsLab - Physics Simulation with Java.
  • Index of Circuit Examples - Demonstrates various electronic circuits.
  • Digital Filters - Filters digital signals and plays the output on your speakers.
  • Acoustic Interference Applet - Audio interference between your speakers.
  • Waveguide Modes Applet - Electromagnetic waves in a waveguide.
  • Antenna Applet - Generates antenna radiation patterns.

Analog Circuit Simulator Applet - Demonstrates various electronic circuits.

"This java applet is an electronic circuit simulator.  When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage.  The gray color indicates ground.  A red color indicates negative voltage.  The moving yellow dots indicate current."

iCircuit is the easy to use electronic circuit simulator and designer - the perfect tool for students, hobbyists, and engineers.

Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.

Learn + Make + Teach Electronics at EveryCircuit

Build any circuit, tap play button, and watch dynamic voltage, current, and charge animations. This gives you insight into circuit operation like no equation does. While simulation is running, adjust circuit parameters with analog knob, and the circuit responds to your actions in real time.

Getting Started in Electronics - Forrest M Mims III

Begin With the Basics - Learn about static electricity and how to make magnets and solenoids. Find out about direct current and alternating current. Then learn about electrical circuits that use batteries and lamps.

Forrest Mim's Science Web site

Mims was interested in science at an early age, and he built an analog computer as a high school science fair project in 1960. While memorizing his Latin class vocabulary words, Mims conceived a computer that could translate twenty words from one language to another.

Forrest M. Mims III is an American amateur scientist

The input was six potentiometers (variable resistors) each having a dial with 26 letters. Entering the first six letters of the word on the potentiometers set a total electrical resistance. The memory of known words was a bank of 20 screwdriver-adjustable trimmer resistors.
