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...
Its been more than two weeks that i am designing a new bench power supply with adjustable dual polarity and non adjustable 5V. Which includes safety fuse and LCD or 7Segment display to monitor current and voltage.. but still not decided to which to put.
The transformer used in the power supply is re wound to make it center tap. Before it has only one coil in secondary so i disassemble the transformer and re wound it again for my needs.
The rectifiers are circuit's taken from a computer power supply from junk. The diodes in the rectifier is high current diodes so i planed to cut the part out from a power supply.
For variable +15V i used LM317 and for -15V i use LM337. Still i am waiting for my component orders. Once 5K VR arrives i will finish this project.
