Six months of design iterations, sourcing headaches, and a broken oscilloscope later — I am pleased to share a hardware module I designed to extend the Flipper ecosystem for RF security research. This write-up covers the motivation, engineering challenges, capabilities, and responsible-disclosure principles behind the project — and a frank look at a vulnerability that is very much alive in the Maldives today. Left: 3D render of final PCB · Right: Altium Designer PCB layout view Why I Built It The trigger was reading the original MouseJack disclosure by Bastille Networks. It made me realize that a class of peripherals most people assume to be harmless — the cheap wireless mouse on your desk — can be weaponized from a car park. I wanted a research platform small enough to carry in a jacket pocket, native to the Flipper Zero ecosystem, and capable of passive scanning, protocol analysis, and controlled lab tests. What I...
Here is a thing that i have faced few times when it comes to GPS data. Below is the GPGGA string from NMEA data receives from GPS. I have highlighted the latitude and longitude from the string. $GPGGA,081902.00, 0412.75469 ,N, 07332.48758 ,E,1,08,0.97,10.7,M,-93.5,M,,*41 Latitude = 0412.75469 Longitude = 07332.48758 If you want to plot this in google maps or any other platform you need to convert this data to decimal degrees, which will be easy to point the location rather than using raw data. In order to do that please follow these steps and write your own math function for this. For my purpose i am using my own function to handle the conversions. First lets start with latitude. Get rid of the zero first. rawdate = 4 12.75469 in this case 4 is the degrees which is in blue color and minutes in green Formula: degrees = 4 minutes = rawdate - (100*degrees) minutes = 412.75469 - (100*4) minutes = 12.75469 So to find out the decimal ...
