1 × Adafruit Trinket 5V ATtiny85 microcontroller board, USB programmable. https://learn.adafruit.com/introducing-trinket/introduction
1 × Adafruit MMA8451 Accelerometer Breakout 3-axis accelerometer board using I2C. https://learn.adafruit.com/adafruit-mma8451-accelerometer-breakout/
1 × Adafruit Mini 8x8 LED Matrix with I2C backpack LED display matrix with I2C. https://www.adafruit.com/products/870
1 × 4-pin female header
2 × CR2025 batteries
1 × Through hole prototyping board This was used for wiring the Trinket, MMA8451, and LED matrix. A real PCB would be better.
4 × 2mm hex nuts
4 × 2mmx19mm bolts I used the 19mm bolts because I had them but 15mm would probably fit better with my current enclosure design.
1 × Switch with on/off push button Small power switch from ebay
1 × 3D printed enclosure This houses all of the electronics and emulates a traditional dice. The OpenSCAD file is on the project github page.
1 × 3D printed battery holder Holder for the two CR2025 batteries. Design modified from http://www.thingiverse.com/thing:190643.
