Small Electronic dice circuit that fits in an actual dice

The following are the project requirements: Designing a smallest electronic dice on a flexible PCB board that Fit into an actual dice The electronic dice will have a smallest microcontroller that can run on button batteries, tilt sensor or an accelerometer that can detect the start and end of the roll of the actual dice, 7 RGB LEDs on each side of the Dice cube. The electronic dice will have the designed PCB inside an actual dice When the user rolls this dice by actually throwing like a normal dice, the sensor activates and stops after the end of the roll Confidentiality: This email and any attachments are confidential and may be subject to copyright, legal or some other professional privilege.
