Electronics Concepts at HyperPhysics
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."

1-Wire Barometer - 5/10 Volt Design
"The circuit requires an additional power source other than that of the 1-Wire network. The MPX4115 requires about 7 ma of current. This is more than a 1-Wire network can provide without an elaborate circuit to store parasitic power from the 1-Wire network for short burst of current for pressure measurements."
Wire Drivers-Getting Started
1-Wire drivers allow communication between a personal computer and Maxim's 1-Wire or iButton products, and they are provided for download free of charge. Also bundled with the 1-Wire drivers download is the OneWireViewer demonstration application software. To get started, you will need the following:

Phoenix Science Experiments
Phoenix depends heavily on Python language. The data acquisition, analysis and writing simulation programs to teach science and computation.
Different sensors elements can be interfaced and accessed by few lines of Pythoncode. Phoenix utilizes the power of personal computers for experiment control, data acquisition and its mathematical analysis.
PMDK is an easy-to-use, low cost micro-controller development system. The hardware consists of an ATmega16MCU, LCD display and regulated DC supply. All the I/O pins of the MCU are available on sockets.
The instrument is designed using locally available low cost components and the design is freely available for commercial production. Design supports hardware plug-in modules for expansion. Phoenix is developed using Free Software tools.
The serial and USB versions can be easily interfaced to a PC. They can also be programmed through the serial/USB ports after uploading a bootloader program to ATmega16.

These Tutors which are Interactive as well are useful for Students and Enthusiasts to enhance the Text Book reading.
These pages are good for any person who want to be more familiar with magnetism and electricity. This probably means everyone. Today Electricity Basics is General Knowledge and also an Absolute Essential.
Interactive Java Tutorials - Covers principles, physics, and devices used in electricity and magnetism.

This Website is a valuable resource for students to learn basics and get interested in electronics and computers - delabs
Electromagnetism: - An electric motor in 10 minutes
The motor is simply a battery, a magnet, and a small coil of wire you make yourself. There is a secret to making it (which I will of course share with you) which is at the same time clever and delightfully simple.
Other Projects - Fun with High Voltage, A 10 minute railgun, A 30 second motor.
The reason a crystal radio does not need any batteries is the amazing capabilities of the human ear. The ear is extremely sensitive to very faint sounds. The crystal radio uses only the energy of the radio waves sent by radio transmitters.
Others are Building a radio in 10 minutes, Build a portable crystal radio, A radio out of household items, A simple AM transmitter, The Three-Penny Radio.
In this project we will build a very simple radio transmitter that you attach to a serial port on your computer. The computer then runs a free program that converts words you type into radio signals that are decoded by another computer, using a cheap radio receiver, and a sound card.
