A completely synthesizeable IP core of a Real Time Clock (RTC) is presented here. Specifications 1. Alarm Set capability 2. AM/PM notification 3. Last Alarm time memory Info HDL used  : VHDL Tested on an Altera DE2 FPGA deveopment board.see the screenshots. Download link to source VHDL files http://www.mediafire.com/?ud1bt4zl05y5v6s Bugs are always tricky.. so download, try , and report back if any exists.. But i am sure u will love to explore the code because.. it will teach u abt reading hardware pins, using it in digital logic.. driving 'LED 7 segments' and interacting with the design using push buttons and slide switches etc....

Hey.. guys... Let us see another idea.. Simply it is to make your Desktop Bluetooth enabled without using any rear/front USB ports but still by using a cheap USB Bluetooth dongle.. Even somebody got the idea.. i guess.. the smell of a hot soldering iron.. Let us start.. Basics  Use the extra available USB internal headers on a motherboard (refer mobo manuals). Nowdays all mobos have plenty of such headers.. but rarely used by any user.. So... Ingrediants needed. 1. A female USB port.. (screw some friend of yours having a Pentium 2 or 3  PC. ) 2. Wire harness of old PC speaker and front pannel connector (u r again lucky to have such a friend). 3. A small lined PCB. (Cut it around with just 4 lines at a length of 2 cm.. ) 4. The usuals.. obviously the Iron, solder paste, solder lead etc... Design Methodology Solder the 4 wire harness on the 4 lines of PCB. Understand the board connectors from the skteches. Also understand the four copper contact...

Some new networks allow to retrieve the mobile number (MSISDN) from the network. You can use this facility to know the mobile number of ur unknown SIM card(if u have lot of SIMs)that u had forgotten for long time and now just found it in your old purse. These codes worked for me. *1# *7# I have tried almost all networks of which airtel and idea didnt reponded. Add if any similar code worked for u... An update : *789# for idea

Justlike IMEI number for each mobile phone, every SIM card is provided with an IMSI number. It is useful if u know it incase u lost ur sim card IMSI- International Mobile Subscriber Identity If u have a BSNL 3G or 2G SIM card , the u can retrieve your IMSI number by caling *115# from your mobile.

WORKS ON MOST NETWORKS PRESS CALL BUTTON AFTER DIALING THESE CODES *43#                 activate call waiting *#43#               call waiting status #43#                 deactivate call waiting *#61#                call divert status

    NOKIA SECRET CODES works on allmost all nokia phones On the standby screen, dial *#06#                           IMEI (serial number) *#0000#                      firmware details *#92702689#              life timer *#2820#                       Bluetooth MAC Address *#62209526#             WLAN MAC Address *#9990#                      Bluetooth Test Mode *#7370# AND *#7780#           Restore original phone settings

Many phones have TV out facility but the cable does not come in standard packaging box. We have to buy it additional. It would cost hundreds for original cables I have made a TV out cable for my Nokia N79 long back. Same trick could be applied for other brands once you know the pinouts of 3.5mm jack correctly. All you need is 1) 3.5 mm HEADSET connector with 4 contacts. ( u can buy headsets of china mobile phones having 3.5mm jack for that) 2) An old AV cable used to connect DVD players with TV(costs only 40 for new) The microphone contact of the 3.5mm jack is used for carrying video signals to TV (for nokia). Other two contacts are used for left and right audio channels. The fourth contact is the common ground for video,left audio,right audio. The contact line designations starting from the tip of 3.5mm jack is 1--right audio 2--left audio 3--mic (video: in our use) 4--common ground Guys take up your soldering irons and assemble yourself Enjoy videos and movie files on your...
