Simple wireless hacking : How to change the MAC address of a Windows machine

This will help you to  change the MAC address of a Windows machine.

 

Change Registry

This howto requires little knowledge on the Windows Registry. Also, make sure you have a good backup of your registry.

• Goto command prompt and type "ipconfig /all", and
• Note the Description for the NIC you want to change.
• Not the MAC Address for the NIC you want to change
• Goto command prompt and type "net config rdr", and remember the number between the long number (GUID) inside the { }. For example, for MAC address "00C095ECB794," you should remember "{1C9324AD-ADB7-4920-B02D-AB281838647A}". You can copy and paste it to the Notepad, that's probably the easiest way.
• Go to Start -> Run, type "regedt32" to start registry editor. Do not use "Regedit."
• Do a BACKUP of your registry in case you screw up the following steps.
• Click on "HKEY_LOCAL_MACHINE on Local Machine" sub-window
• Click on the root key "HKEY_LOCAL_MACHINE".
• Click on the drop-down menu "Registry -> Save Subtree As" and save the backup registry in to a file. Keep this file in a safe place.
• Go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}". Double click on it to expand the tree. The subkeys are 4-digit numbers, which represent particular network adapters. You should see it starts with 0000, then 0001, 0002, 0003 and so on.
• Go through each subkey that starts with 0000. Click on 0000, check DriverDesc keyword on the right to see if that's the NIC you want to change the MAC address. The DriveDesc should match the Description you recorded from step (a.-I.). If you are not 100% sure about the DriverDesc, then you can verify by checking if the NetCfgInstanceID keyword value matches the GUID.
• If there is no match, then move on to 0001, 0002, 0003, and so on, until you find the one you want. Usually 0000 contains the first NIC you installed on the computer.
• In this demonstration, 0000 is the NIC I selected.
• Once you selected the subkey (i.e. 0000), check if there is a keyword "NetworkAddress" exist in the right side of the window.
• If "NetworkAddress" keyword does not exist, then create this new keyword:
• Click on the drop down menu "Edit -> Add Value".
• In the Add Value window, enter the following value then click OK.
• Value Name: = NetworkAddress
• Data Type: = REG_SZ
• String Editor window will pop up at this time
• Enter the new MAC address you want to modify. Then click OK.
• (There should not be any "-" in this address. Your entry should only consist of 12 digits.
• If "NetworkAddress" keyword exists, make sure it shows the keyword type is REG_SZ, and it should show as NetworkAddress:REG_SZ: . This keyword might not have a value at this time.
• Double click on the keyword NetworkAddress and the String Editor window will pop up.
• Enter the new MAC address you want to modify. Then click OK. (There should not be any "-" in this address. Your entry should only consist of 12 digits).
• Goto Start->Setting->Control Panel, and double click on "Network Neighborhood".
• Select the Network Adaptor you just changed the MAC address.
• Disable and enable the adaptor
• At the command prompt, type "ipconfig /all" to confirm the new MAC address.

Thesis on Advanced Single-Stage Power Factor Correction Techniques

Five new single-stage power factor correction (PFC) techniques are developed for single-phase applications. These converters are: Integrated single-stage PFC converters, voltage source charge pump power factor correction (VS-CPPFC) converters, current source CPPFC converters, combined voltage source current source (VSCS) CPPFC converters, and continuous input current (CIC) CPPFC converters.

Integrated single-stage PFC converters are first developed, which combine the PFC converter with a DC/DC converter into a single-stage converter. DC bus voltage stress at light load for the single-stage PFC converters are analyzed. DC bus voltage feedback concept is proposed to reduce the DC bus voltage stress at light load. The principle of operations of proposed converters are presented, implemented and evaluated. The experimental results verify the theoretical analysis.

VS-CPPFC technique use a capacitor in series with a high frequency voltage source to achieve the PFC function. In this way, the input inductor is eliminated. VS-CPPFC AC/DC converters are developed, and their performance is evaluated. VS-CPPFC electronic ballasts with and without dimming function are also presented. The average lamp current control with duty ratio modulation is developed so that the lamp operates in constant power with a low crest factor over the line variation. The experimental results verify the CPPFC concept.

CS-CPPFC technique employs a capacitor in parallel with a high frequency current source to obtain the PFC function. The unity power factor condition and principle of operation are analyzed. By doing so, the switch has less switching current stress, and deals only with the resonant inductor current. Design considerations and experimental results of the CS-CPPFC electronic ballast are presented.

VSCS-CPPFC technique integrates the VS-CPPFC with the CS-CPPFC converters. The circuit derivation, unity power factor condition and design considerations are presented. The developed VSCS-CPPFC converters has constant lamp operation, low crest factor with a high power factor even without any feedback control.

CIC-CPPFC technique is developed by inserting a small inductor in series with the line rectifier for the conceptual VS-CPPFC, CS-CPPFC and VSCS-CPPFC circuits. The circuit derivation and its unity power factor condition are discussed. The input current can be designed to be continuous, and a small line input filter can be used. The circulating current in the resonant tank and the switching current stress are minimized. The average lamp current control with switching frequency modulation is developed, so the developed electronic ballast operates in constant power, low crest factor. The developed CIC-CPPFC electronic ballast has features of low line input current harmonics, constant lamp power, low crest factor, continuous input current, low DC bus voltage stress, small circulating current and switching current stress over a wide range of line input voltage.

Design and Implementation of computer Interfacing based Thermometer

The Project is classified into following four sections:

1. Sensing section
2. Measuring section
3. Conditioning or amplification section
4. Interfacing or data acquisition section.
5. Display section.

Sensing and measuring section sense temperature and convert it into electrical quantity as voltage. Conditioning or amplification section amplifies the measuring section output, which is the input of data acquisition section. For conditioning we use non inverting amplifier. At data acquisition section we use analog to digital converter(ADC) for digital output and a multiplexer for converting ADC output from parallel to serial. The multiplexer output is sensed by a parallel port of personal computer by Matlab. Then the digital value is converted to decimal. From temperature versus voltage equation we get measured temperature.
