Portal Companion Cube with LEDS
thingiverse
 I crafted a Portal Companion cube with LEDs, powered by an ATtiny85 microcontroller that dictates the light show. Users can customize the effect by programming it. To bring this project to life, you'll need to 3D print several components: - One Cube_Hollow - Four Corner_Gray_Down pieces - Four Corner_Gray_Up pieces - Eight Corner_White pieces - Twelve Bit pieces - Five Center pieces - Optional: five Heart pieces - Cover_Electronics piece - Optional: a Cover_Simple piece, which serves as a housing for the electronics without the outer casing Note: Currently, there's an issue when powering on the cube. At startup, it briefly displays a bright white light before transitioning to the intended effect after 5 seconds. This delay is caused by the ATtiny85 loading its program code.
