Design and assemble a hardware pentest rig: pick a Pi (4B or 5) or ESP32, a USB Wi-Fi adapter (Alfa or equivalent), an LTE dongle, a power solution (battery + PD), and a form factor (workstation / drop box / implant). Document the bill of materials with prices, the loadout for one scenario (e.g., 4-hour office walk-in), and the OPSEC profile (what survives if seized). Boot it, verify all interfaces work, and submit a photo + diagram + write-up.
