A Raspberry Pi–powered CCTV hub delivering a smooth 720p MJPEG live stream with real‑time OpenCV motion detection, automatic or manual RGB‑LED alerts, one‑click 1080p snapshot captures sent directly to the client, and instant push notifications for all key events.
Python application using LabJack UE9 for DC motor PWM control, TMP36 temperature sensing, and hardware safety via Emergency‑Stop/Reset. Includes speed presets and a multithreaded terminal UI for real‑time, non‑blocking user input.
A compact DC power supply was engineered to deliver a variable output of 2–14 volts at up to 1 amp. Starting from a step‑down transformer, the precision regulation circuitry was laid out on a custom PCB, and a 1 A fuse was added on the AC input for overcurrent protection. The entire assembly is housed in a robust aluminum enclosure that successfully passed both drop‐tests and high‑potential (“hi‑pot”) insulation tests.
Using Covenant C2 in Docker, we delivered a PowerShell payload via a malicious .docm, spawned a reverse shell with persiststartup persistence, and tracked the “payload1” download in Security Onion/Suricata logs. We then isolated the host, removed all artifacts, blocked the attacker’s IP, and verified cleanup through Kibana.
Deployed a Fedora‑based office network environment automating critical services—DHCP, DNS, NFS, Samba, mail, web, and VNC—via shell scripts and cron jobs. Configured secure user roles, scheduled backups, remote printing, and firewall policies, showcasing comprehensive Linux administration and network orchestration skills.
