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.

What's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are 'multiplexed' - ...
The "poor man's" accelerometer/motion sensor! These spring-vibration switches are high sensitivity non-directional vibration induced trigger switches. Inside is a very soft ...
The Adafruit Trinket M0 may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. We ...
Lithium-ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, light, and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has ...
If you have an ItsyBitsy or Pro Trinket you probably know it's the perfect little size for a portable project. This LiPoly backpack makes it really easy to do! Instead of wiring 2 or 3 ...
