Cyberdeck
A portable, purpose-built platform for cybersecurity experimentation.
01overview
The Cyberdeck is an experimental computing platform: a portable ESP32-S3 device with a TFT display, dual nRF24L01 radios, GPS, microSD storage and a full physical input system, all wrapped in custom firmware.
The firmware ships a menu-driven toolkit — WiFi scanner, threat monitor, WiFi audit, probe sniffer, 2.4 GHz spectrum analysis with RF baseline, BLE audit and scanner, GPS Tools Pro with CSV logging and waypoints, plus a microSD manager that exports reports in CSV/TXT.
All tooling is defensive and designed for legal, ethical use on owned or authorised networks and labs. A web-based serial flasher makes the firmware simple to deploy.

06problems & solutions
Balancing many peripherals (display, two radios, GPS, SD) on one ESP32-S3 without resource collisions.
Dedicated SPI buses and pinouts per peripheral (documented in the firmware README), plus an NVS-backed settings store for persistent configuration.
Building a usable UI on a small TFT with only four buttons and an encoder.
A custom menu system and UI engine designed for encoder navigation and OK/back semantics.
