What i am making here is a USB lock with smartcard key. The idea is that a phonecard reader made with a PIC micro will be able to store a number of different phonecards into memory. Whenever one of these cards is inserted into the slot, it will activate a 4-ports USB On/Off switch. If the card is removed, the USB ports will be de-activated. [ ]

Here is the software Smart Sine, that I created and now use to generate sine tables. It is the improved and more developed version of the software I had previously created with a few more useful features. It is relatively simple to use and gives results quickly as opposed to manually calculating the table. If the software asks for .NET Framework Installation, you can download it from: http://www.microsoft.com/en-us/download/details.aspx?id=17851 or http://www.filehippo.com/download_dotnet_framework_4/ Download the software from : Recommended: https://drive.google.com/file/d/0B4SoPFPRNziHWVdLYVFKeHlsWjQ/view?usp=sharing Alternate link: http://www.4shared.com/zip/L2RbV7Hz/Smart_Sine.html Here are a few screenshots:

             The project aims to design and implement a E-bus prepaid smart card system which is a simple way to travel . The smart card carries electronic money instead of cash and it is rechargeable. A smart card reader is available on buses which is located at the entrance door of the bus. The main part of the project is PIC microcontroller to which all the modules necessary for this project are interfaced. IR sensor is also interfaced to the microcontroller and the count of the persons can be taken. The smart card reader displays all the information of the journeys.             A smart card, chip card, or integrated circuit card (ICC), is any pocket-sized card with embedded integrated circuits. A smart card or microprocessor cards contain volatile memory and microprocessor components. The card is made of plastic, generally polyvinyl chloride, but sometimes acrylonitrile butadiene styrene or pol...

Daylight harvesting is becoming increasingly important in the design and implementation of commercial lighting systems. Being able to integrate the natural light from windows with flexible, controllable sources of lighting helps improve the work environment and cut energy bills. Being able to have closer control of the lighting systems in a commercial environment is a key element to this strategy and energy harvesting can play an important role. Being able to have flexible placement of control pads for a commercial lighting system is an important requirement as office space is regularly reconfigured as existing clients grow and change their requirements and new clients have new requirements.

You can easily convert your ordinary docking station into a smart electronic laptop docking station with antitheft alarm. Circuit diagram : Fig. 1: Circuit for laptop docking station with antitheft alarm The add-on sensor circuit required for this is built around IC CNY70 (IC1) and IC CD4060 (IC2) as shown in Fig. 1. IC CNY70 is an integrated reflective-type opto-sensor that contains a photo-transistor and an infrared LED. The LED emits infrared light and the transistor works as a receiver. The current flowing through the phototransistor depends on the intensity of the light detected.  IC CD4060 is a 14-stage ripple-carry binary counter. The counter is reset to zero by a gating positive voltage at the reset input independent of clock. Power supply to the circuit is derived from AC mains by using step-down transformer X1. The transformer output is rectified by a full-wave bridge rectifier comprising diodes D1 through D4 and smoothed by capacitor C1. When power switch S1 is in ‘on...

Perhaps not everyone knows that Nokia, before absorption of its "mobile" division of Microsoft, released the same budget-Android-smartphone for two SIM-cards - Nokia X. Despite the fact that the Android OS there very greatly curtailed - no services Google and Play Market application store and the interface very much resembles Windows Phone - the smartphone sold very well due to its low price and the possibility of a relatively simple "do livability" functional. Contrary to logic, Microsoft did not cover the range of X and more - has announced a new smartphone in this still numerically small family - Nokia X2 . I do not know what guided in by Microsoft, but X2 is sold with preinstalled online store Google Play, which is very strange, as a direct competitor to Google Play Windows Phone Store from Microsoft. But the main "trick» Nokia X2 is not the case. The smartphone will be on board the two operating systems - Android and Windows Phone! While it is unknown how...
