Electronic dice

Got the idea from a post I saw here a few months ago. Someone waned an idea for a project. Doing a deslpay of 1..6 die on a matrix caught my eye. Why not a ball with a display on each side? Vibration sensor to trigger it to select a number. LIPo battery & charger? Easy peasy! NOT. Nightmare to assemble! Parts involved. 8x8 matrix, need 2 of 'em : https://www.adafruit.com/product/1080 Vibration sensor : https://www.adafruit.com/product/1766 Trinket MO (tiny) : https://www.adafruit.com/product/3500 Little LiPO 150mAH : https://www.adafruit.com/product/1317 Tiny LiPo charger : https://www.adafruit.com/product/2124 Itty bitty switch : https://www.adafruit.com/product/805 Silicon coated wire : https://www.adafruit.com/product/3165 Get every color they sell. There is no way to build this using regular hookup wire. This suff is tiny, immue to solder iron heat. And extremely flexible.
