A tiny 8x8 matrix clock that automatically rotates the display when the cube is rotated.

Recently I stubbled across the Lexon Flip Travel Reversible LCD Alarm Clock. It got me wondering about a clock that always showed the time in the same orientation no matter what orientation the clock itself was in. I decided to use a 8x8 Matrix as the display in a case that is basically a cube.

Because a 8x8 LED matrix can’t show the complete time as text, the text needs to scroll. I decided to use mercury switches to determine the orientation of the cube as they are small and relatively cheap compared to a MEMS unit (Micro Electro Mechanical System) such as the MPU-6050 6-axis accelerometer/gyroscope.”
