What about having a versatile WiFi/BLe hacking tool on your wrist ? Imagine this: you walk into a room/building/premise/whatever and use your watch to scan/detect nearby WiFi networks, BLE devices, and get information about them. Maybe you would also be able to try one or two attacks that may be implemented into this firmware :).

Well, it is basically an ESP32-based smartwatch with:

• a capacitive touch screen (240x240 pixels)
• a 3-axis accelerometer
• a speaker
• a battery (of course)
• an IR LED (well, could be useful)
• an embedded real-time clock (obviously, it's a watch !)

• Get Espressif's ESP-IDF framework (version 4.4.2) and install it (following the instructions at https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/)
• type idf.py build or idf.py -p <your USB port> flash to build this project or/and flash your smartwatch
