Electronics Concepts at HyperPhysics

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..

Electronics Concepts at HyperPhysics

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

Ampere Law at HyperPhysics

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."

David Bray 1-Wire Barometer

This article describes details for constructing a 1-Wire Barometer which will work on a Dallas Semiconductor Corporation 1-Wire network. This design differs from the popular Version 1.1a in that it has more than twice the resolution. - David W. Bray

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."

David Bray 1-Wire Barometer

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 allows you to develop science experiments  by connecting  sensor / control elements to a computer and access them through software.

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.

Phoenix Science Experiments

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.

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.
    Radio: A quick and simple radio

    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.
      Computers and Electronics: A Computer Controlled Transmitter

      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.
