DIGITAL SYSTEM DESIGN by M.Morris Mano & Michael D.ciletti

TINA Design Suite v8.0 - PCB Industrial version

TINA Design Suite is a powerful yet affordable circuit simulation and PCB design software package for analyzing, designing, and real time testing of analog, digital, VHDL, MCU, and mixed electronic circuits and their PCB layouts.

You can also analyze SMPS, RF, communication, and optoelectronic circuits; generate and debug MCU code using the integrated flowchart tool; and test microcontroller applications in a mixed circuit environment. A unique feature of TINA is that you can bring your circuit to life with the optional USB controlled TINALab II hardware, which turns your computer into a powerful, multifunction T&M instrument. Electrical engineers will find TINA an easy to use, high performance tool, while educators will welcome its unique features for the training environment.

ELECTRONIC WATCHDOG

Here’s an electronic watchdog for your house that sounds to inform you that somebody is at the gate.  :D :))))

Circuit Diagram, Arrangement & Component Data (Rx & Tx)

 The circuit comprises a transmitter unit and a receiver unit, which are mounted face to face on the opposite pillars of the gate such that the IR beam gets interrupted when someone is standing at the gate or passing through it.

How to Delete, Modify or Disable an Incorrect or Duplicate Entry on the XP Boot Menu

There are two options to get around this: You can remove the offending boot menu item, or you can just turn off the boot menu from being displayed. If you aren’t tech savvy, you’ll want to just use the second option.

Removing an Incorrect Boot Menu Option on XP

Note: This method involves modifying a very important boot configuration file. You should proceed with caution and always make sure you have backups of your files just in case something goes wrong.

All of the boot menu options in Windows XP are stored in the boot.ini file in the root of your boot drive, usually the C: drive. You’ll need to first set the file to be writeable by using the attrib command from the command prompt:
