Dear friends, followers, InfoSec enthusiasts,
I AM OUT FOR A WHILE!
I will take a break from all public work, as I need more time for my beloved ones.
This will affect projects like P4wnP1, P4wnP1 ALOA, LOGITacker and BLExy, as well ass all pending invitations to conferences.

P4wnP1 on the Zero 2 W? Sure why not
Detailed documentation? Sure why not
New images and instructions to do your own? Sure why not
New attacks per default? Sure why not.
Was down in the rabbit hole for days ... Enjoy.
Thx @mame82 and @RoganDawes

LOGITacker by @RoganDawes/@mame82 did no longer
- compile firmware
- hide PowerShell for covert channel
I removed verbosity and added a Dockerfile
+ helperscript to build the fw for the MD Dongle.
Now works and is stealthy again

Using budget skates from @OxeloOfficial and thought it might be a good idea to learn to stop without heel brake ... So I slightly changed the setup iot remove the break
- Oxelo MF500
- Endless 4x90/3x110 MK2
- Bones super red bearings

Realtime gyro driven fluid simulation on @EspressifSystem ESP32-S3
(Combination of FLIP and PIC, 512 particles, 32x32 fluid grid)
Eulerian fluid simulation runnable n same device:xitter.cf/mame82/status/19078674…
Realtime Fluid Simulation on cheap @EspressifSystem esp32-s3 board with round 1.28" touch LCD.
What a powerhouse:
- 32x32 simulation grid
- 240x240 interpolated rendering
- back button toggles mode (adding ink/interact with fluid velocity)
- ~20fps @ 240MHz

Got a bit tired of eye animations ... next experiment on @EspressifSystem esp32-s3
Realtime 2D fluid simulation with ESP-IDF
- 24x24 simulation grid
- 32 bit float
- result rendered at 128x128 px (with interpolation)
- additional threads for wifi AP, BLE Central +peripheral
Still testing what's possible, this app currently has concurrent threads for:
- WiFi (AP mode)
- HTTP server
- BLE coexistence, with Nimble running a central and peripheral + concurrent scanning and advertising (requires tuning of scan/adv intervals to keep wifi working)
In addition it runs a JavaScript engine based on Jerryscript (esp-idf module available, my PR to make it work on SPIRAM was accepted, otherwise it wouldn't have been possible to run it on top of this):

Just for fun ... Inspired by @adafruit "uncanny eyes", but written from scratch for esp32-s3 touch lcd (+IMU)
- full screen rendering 240x240x16
- 20 to 30fps
- WiFi HTTP runs concurrently
- only 1 core in use
Zephyr was way more abstract and complicated and hard to configure. Also ESP-IDF has a way better VSCode extension (build/debug setup).
Speaking of debugging: if you intend to use esp32-s3 built-in JTAG, the 1.28" round display boards from @waveshare00 aren't a good choice..
