A fancy camera with an e-paper display and an accelerometer so you can shake it to display captured photos!
Overview
The E-Paper Polaroid Badge is was a planned Unofficial DEF CON badge featuring:
4.2” E-Paper Display
OV2640 Camera
Accelerometer (Shake To Reveal, like a polaroid!)
SD Storage
Bluetooth
Li-Po Battery Powered with optional Full USB Bypass (for when the conference is over and you want to power it 24/7)
Many RGB LEDs
LED-based Flash
Ambient Light Detection
A COTS cobbled version of this design was worn at #DEFCON32.
State
Killed in the crib.
Note: I stopped working on this project after I saw that I had missed that Adafruit has an OV2640 camera that is almost the exact design I was making except with an OLED or something instead of an e-paper.
Unlike other low-cost EMFI tools, the Dirt Cheap EMP features no controller and must be operated by an external fast-gpio capable device, such as a Raspberry Pi RP 2040/2350. An optional RP2040-based controller is also in development.
The EMP device is designed to be XYZ-stage mounted using the same format as a 40mm fan, with 4 4.1mm mounting holes spaced in a square at 32mm from one another. This format allows the device to be mounted on most 3D printer toolheads, as well as on similar easily DIY-made solutions. While traditional commercial and industrial XYZ-stage solutions can cost from hundreds to many thousands of dollars, an adequately comparable level of precision for the purposes of EMFI attacks against consumer-grade hardware can be achieved for a significantly lower cost.
This lowers the barrier to entry for performing more well-automated attacks against chip packages by more hackers. Tactical diffusion, democratization of access.
The Dirt Cheap JTAG Adapter is designed for adapting common 2x10/2.54mm and 2x5/1.27mm JTAG/SWD connectors with one another. The adapter connects directly to bothSEGGER J-LinkANDSEGGER J-Link Mini models and provides easily accessible 2x10 and 2x5 headers.
For those of you who have modded your J-Link to add 3.3v output , pin 2 is connected across the board and separate from GND, so this adapter will work just fine for you.

All good the adapter works well, needed for the project. Cheers!
