BLIND-CAM
A handheld scope for the invisible world.
Real-time Wi-Fi Channel State Information (CSI) visualization powered by ESP32.
The "Blind" Concept
Cameras capture light; the Blind-Cam captures data. We are swimming in a sea of Wi-Fi signals that bounce off walls, furniture, and bodies.
By decoding the Channel State Information (CSI) on a portable device, we can "see" movement and environmental changes without a lens. It effectively acts as a handheld sonar for the electromagnetic spectrum.
CURRENT CAPABILITIES
- ✔ Sniffer Mode: Passive traffic monitoring.
- ✔ Portable: Battery operated & self-contained.
- ✔ Live Viz: 60FPS TFT rendering.
- ⏳ Station Mode: Uplink injection (In Dev).
Modular Housing Design
Designed in CAD and fabricated at the Makers Space, the unit is split into two distinct functional modules (body & cover) to allow for easy maintenance and friendly design.
01. The Body
Friction-fit enclosure for the ESP32 & TFT.
02. The Cover
easy on/off cover for simple assembly
