Openterface KeyMod is a compact USB/Bluetooth HID emulator that turns your phone into a portable keyboard and trackpad. This project shows a quick, repeatable setup for local control of kiosks, signage players, mini PCs, and lab rigs when a full keyboard and mouse aren’t at hand.

Phantom is an advanced intelligent anti-surveillance system based on active infrared optical recognition and interference technology. The system utilizes invisible infrared light emission to capture unique reflection characteristics of camera lenses, enabling automatic detection and positioning, followed by precise directional infrared laser interference to temporarily disable camera sensors, achieving optical stealth effects.

R4TKN Deauther transforms the Ai-Thinker BW16 (RTL8720DN) into a dual-band 2.4/5 GHz Wi-Fi security lab tool, simulating disconnection events to audit and harden networks—featuring a portable, TFT-driven UI for authorized testing only.
