Home Automation over Internet complete project

You can now download project documentation and code for project "Home Automation Over Internet" as well as power point presnatation. I have also bundled the complete VB software code of Server, C code for microcontroller, schematic diagram, sample images in a single zip file so you need not download multiple files. If you have any doubt feel free to post your doubts here www.8051projects.net.

Basic Computer Operation Tutorials

Unfortunately, most technical tutorials seem to be written to those who already have a complete understanding of the subject matter. This tutorial on basic computer operation is intended to help virtually anyone who wants to learn more about operating a computer (you don't have to be a geek to understand it). It will start out with the most basic information and will progress from there. I will cover mainly Microsoft Windows XP and its bundled software but I will also cover some of my favorite software.

Basic Car Audio Electronics

This site will help you to understand basic electronics and some electronic devices. It will, of course, also touch on car audio acoustics and car audio equipment. To make the lessons as painless as possible, you'll find hundreds of diagrams and pictures, .wav files and more than 50 javascript calculators on the 125+ individual web pages. If you make even a modest effort, you'll learn more about car audio electronics than you ever thought possible.

PICBASIC proton user project

Welcome to the Proton Users site, a site dedicated to Proton Basic and Proton Plus compilers. It was conceived to provide a better place to add your “Projects”, and “How to’s”, whether simple snippets or full-blown tutorials. We have managed to put together some interesting stuff to get started with so enjoy.

Many thanks to Lester and his team for the site and underlying coding, and a very big thanks to Oliver and son for all the hard work adding those special touches and the bulk of the contributions so far. Please don’t forget it’s your site, WE NEED YOUR INPUT.

Simple Mobile Phone Jammer using 555

Description

A “Cell Jammer” is just way of saying “Dirty Transmitter” which happens to transmit within the Cellular Phone Bands. Reality is, the dirtier the better.

The 555 timer [8 pin] IC simply makes a noise. It’s coupled via C4 [electrolytic] to modulate the MRF transistor oscillator. With C1 set at roughly 1/3rd, you will be close to 900 MHz. By sweeping the C1 trimmer capacitor, you can swing the output frequency from 800 MHz to 2 GHz with the transistor and values shown.

You could replace the 555 chip with an electret microphone and listen to yourself talk on a scanner, so the unit could easily couple as a UHF Bug.

Instead of a single Tapped Coil, I’ve used two molded inductors for ease of construction.Values for C1,C2,L1,L2 are critical for the frequency range.

You might want to build the unit into a metal box, add an on/off switch in the batteries + line, and maybe even add a LED. Connect an old 800 MHz cell phone antenna to C5.

Would you believe the whole thing can be built on top of the 555 IC itself when using surface mount components, and the lot will fit onto a nine volt battery clip. Output is reasonably good, although the current drain is a bit high, so a new 9 Volt battery will only run about an hour, [if you are lucky].

The “Cell Kill Distance” is around 10 – 15 feet, ample for most purposes.
