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

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.”

One of the oldest and reputed Electronics Magazine. construction projects, computer, technology, computing, PC technology, microcontroller. Books & CD-Roms, E-blocks, Kits & Modules.R8C pages, RFID pages.

This was one of the Mags along with Radio Electronics that made me a better designer. Radio Electronics was my first favorite mag.

They have a Forum for Discussion and Displaying your Completed projects. Even seek help when stuck with your project.

Then a Kits and Tools Store where you can buy the things you need to make the Electronic Projects, ..

Elektor Electronics - Hobby Circuits Projects

I though it was time i made a collage for my old guru, then even i am getting older. I wish there was an Internet when i was young. Time to use my rusting Time Machine,

Look no CPU! – Built with MyCPU which is made of discrete logic gates as the Bricks. Homebrew Computer for Education and Experimenting. Dennis Kuschel is  the developer of MyCPU.

Homebrew Computer – MyCPU

The MyCPU is a “Central Processing Unit” that is completely built with discrete logic gates. Over the years the project has grown, and now the MyCPU is the brain of a real Personal Computer. The computer has the following capabilities and features

This can also be roasted on a single FPGA Board.

The “MyCPU v2.3” is ideal for education, and is a nice project for enthusiastic hobbyists. The system uses COM1 for terminal communication and COM2 for file service. The personal computer acts as file server. There are several applications you can use on the MyCPU.
