HACK AND CLONE CAR KEY FOB, MY EPIC FAILURE...!!

- March 05, 2022

In this blog post i'm sharing my experience on cloning the my car key fob signal and how to do it properly. first things frist the cars now a days comes with a wireless remote key where u get atleast 2 or 3 options like lock,unlocking ,trunk(we call it as dickey!!!).....these options let your car access wirelessly and some cars are completly keyless for even driving. the keys of the cars are actually communicating with certain frequency like 433.xxxMHz or some countries uses 315.xxxMHz...the car companies uses an algorithm called " ROLLING CODES "...these are not that esay to crack cause they change every time u press key and once the key transmitted it cannot be used again... but a hacker named "samy kamakar" demonstrated an attack called REPLAY ATTACK where u simply transmitt the signal by recording the key fob away from car or blocking the signal and then recording. so this is how i've tried it..frist i needed to listen to the signals as possible in 10KHz...

"Kernel Panic” error After upgrading Parrot OS

- December 03, 2023

This guide will walk you through the steps of resolving the kernel panic error that you may encounter after upgrading your Parrot OS kernel to version 5.6.0. Step 1: Enter Recovery Mode Restart your computer and enter the GRUB menu by pressing the appropriate key during the boot process. The specific key may vary depending on your computer's manufacturer and BIOS settings. Common keys include F2, F10, Delete, or Esc. Once in the GRUB menu, select "Advanced Mode" using the arrow keys and press Enter. In the Advanced Mode menu, locate the entry for Parrot OS 6.1 and select "Recovery Mode" using the arrow keys. Press Enter to boot into Recovery Mode. Step 2: Purge Problematic Packages Once in Recovery Mode, log in as root using the default credentials. Open a terminal window by selecting "Drop to root shell prompt" from the Recovery Mode menu. ...

1 Best way to add members to Telegram group(2021 using python)

- May 05, 2021

This post for those who want to add members to thier telegram group, which could take forever if we do manually, hence we can automate this take. I 'm using python for this automation. Using the python script called telethon we can add members to the group. T he daliy limit is 200 members. The script adds members with 60-180 sec intervals to avoid bans. you need the following installed in your computer : 1.python 3 (recent one would be better) 2.pip install of python installed(we can enable this option while install python choosing custom install) 3.telethon package installed using pip installer. 4.telegram group api registered in the telegram website. 5.good internet(mandatory) 1.Install python 3 CODE : visit python.org for downloading and installing the windows pacakge. Note: 1.choose the custom installing to enable necessary installers in windows. 2.if you are on the linux or mac python is defaultly ins...

HOW TO WRITE YOUR OWN CODE FOR AN LCD DISPLAY (16X2 OR 16X4)

- May 10, 2021

The Arduino ide default comes with an excellent library with examples for LCD display it’s really easy! One to use. Mine is not best one but the reason behind this post is to experience the feel of writing your own code and understanding the embedded displays and their working technology and how they works with u-controllers, maybe in future it can helps you to write a code for lcd display with other new microcontrollers or other programming languages. So let’s start with the one important things: The datasheet is your friend in this quest for any quest, for real! So getting the data sheet is important here I’m using a 16x2 LCD. This kind LCD is based on parallel interface LCD controller chip from Hitachi called the HD44780. Next is physical pinout the display uses a matrix of dots and displays only characters in 16x2 matrixes. Each character is displayed in a 5 column × 8 row dot matrix or a 5 column × 10 row dot matrix The pinout is LCD has totally 16 pins they are: 1....

HOW TO WRITE A CLASS OBJECT IN PYTHON

- December 17, 2021

The one way to get started with the object oriented programming in python is to get started with the " creating a class object and using it". things u need to get started: 1. Latest version of python3 u can get that from here 2. An ide or u can use python default ide which it comes with! that's all u need to get started. here we are gonna make code for math function called standard scaler(for scaling data). you make one for anything u want I'm just a math guy!! so the math formula for standard scaler is : hence we start with a class object called Scale , the class object doesn't need any input variable for it's name we do it in functions inside of it. The first function inside of class object should be a __init__() " function it must be..! next, an __init__() function should always starts with a " self " variable and other as follows by as other variables u may like... class Scale: def _init_ ( self , data ): ...

MAPPING BIOLOGICAL DATA TO DIGITAL DATA The emergence of molecular biology has produced a vast literature on the cellular function of individual genes and their protein products. It has also generated massive amounts of molecular interaction data derived from high-throughput methods as well as more classical low-throughput methods, such as immunoprecipitation, immunoblotting, and yeast two-hybrid systems. From this accumulation of interaction data, researchers can now attempt to reconstruct and analyses the highly complex molecular networks involved in cellular function. Intracellular molecular networks are known to be highly deregulated in a number of diseases, most notably in cancer, and targeted molecular inhibitors have emerged as a leading anti-cancer strategy. Despite promising pre-clinical studies, many targeted inhibitors are beset by harmful off-target effects and/or lower than expected efficacy in the clinic. The large number of off-target effects associated with m...

DIY VOLTMETER USING ARDUINO ADC

- May 15, 2021

This post helps to DIY yourself a high precision multimeter using Arduino. The UNO already comes with an excellent 10-bit ADC which is enough, but I recommend using an external ADC of 16-bit if you want to take it to serious measurement. But you don’t want you use it as replacement for a multimeter, buy a good multimeter instead of it. This Arduino based one is helpful for projects and static voltages that doesn’t change over the time. We can create a voltage divider hence We can measure voltage drop between the divider and hence multiply with resistance to get the VIN. Here I’m using a 1Kohm and 2.2KOHM resistance to measure max voltage of 5V. If want to measure the higher voltage use the following formula to adjust the resistors. Vout = VIN * (R1R2/R1+R2) [NOTE: This voltage “VOUT” should not have to be more than 5v, I recommend VOUT<less than 5V is safe to use]. Sounds easy because it is, but V_IN cannot be measure hence we need ADC to do trick, the...

MOSFETS FOR LIFTING HEAVY LOADS

- May 05, 2021

This post helps you to understand when to use mosfet’s instead BJT’s. Transistors are one of the best invention that changed the human life, computer uses transistors to work and every sequential logic boards also. But we are interested in using transistors for switching! Heavy loads. Basic functioning of transistor is Switching ON and OFF electronically, this is useful to turn devices or circuit on or off. So this transistors best variants are BJT’s and MOSFET’s, we going to discuss about MOSFET’s today. MOSFET stands for "METAL OXIDE SEMICONDUCTOR FEILD EFFECT TRANSISTOR" which is also like bjt's but can be used to switch heavy loads with VOLTAGE control , unlike bjt's where you have to control using current and power loss is greater in BJT . Mosfet’s can reduce the power dissipation upto 20%, also they can be controlled with voltage unlike current control it is easy. Mosfet’s are 2 types 1 ) ENHANCEMENT TYPE 2) DEPLETION TYPE But one downside is MOSFET gate vol...
