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...
This afternoon i was hard cording some ADC codes. Actual thing i want to do is micro controller's ADC will analyze the given voltage . Actually i am continuing my voltmeter project. I did analog part from LM358. actually an differential amplifier, it handles the high voltage and gives an out put range from 0 - 5 volt.
After some calculations i finally solve the puzzle. Now my micro controlled voltmeter is able to display variable voltage from GLCD (Graphical LCD). Next step is to fine tune the analog circuit and add a new feature or function to display load current.
Many experiments are hold for few days, thing is me too busy some times... ;)
