Machine Learning authentication system, based on a custom Rubik's cube with encoders, inertial and gyroscopic sensors, connectable by Bluetooth Low Energy BLE (Giiker@ compatible).
- 6x 12mm encoders 2-bit Quadrature (Gray coding) like as ALPS EC12 Series
- GY-25 IMU: MPU-6050 & DMP STM32F103C8
- BLE Transceiver: HolyIoT-17095 based on Nordic nRF52832 ARM® Cortex-M4F SoC
- Core Microcontroller: Microchip-Atmel Tiny1634R
- Battery: 3.7v LiPo cell (60mAh) like ref 401215
3D printed cube parts from custom desing (Thank you very much Xavi Val!!!)
Comming soon...
