Catan electronic dice box - extending the game!

thingiverse

https://youtu.be/WB4gXB4nNbw This is an Electronic Dice Simulator designed for extending the board game "Catan". Several modes are available: - Classic Catan (same probabilities as with 2 six-sided dice) - 6&8 Mode: all numbers have the same probability to show up, only 6 and 8 have double odds to appear - Flat Mode: all numbers have the same probability to show up - 1 to 12 Mode: a random number between 1 and 12 will show up, same probability for all. Not suitable for Catan During the setup phase, you can use the main button to select your mode: the dimming state of the numbers is proportional to the probability they show up. Validate with the secondary button. Once validated, you can reset the device with the secondary button. The code is ready for an ATtiny85. However, the reset function won't work on a non-ATtiny-based Arduino; you'll need to use the resetFunc that comes before setup instead. The randomness isn't determined by a function: the processor simply counts as fast as possible in loops from 2 to 12, and when the user presses the button, the LED corresponding to the number at this precise time will light up. I performed two statistical analyses based on 400 and 450 throws for modes 1 (Classic) and 2 (6&8); results are visible in the pictures. For materials, you'll need: - PowerBoost 1000 Charger - Rechargeable 5V Lipo USB Boost @ 1A - 1000C from Adafruit: https://www.adafruit.com/product/2465 - Micro USB breakout board (the most popular size; see Amazon) - A LiPo battery with one cell that will fit (1200mAh should be sufficient); the maximum size is approximately 30*53*12mm. - ATtiny85 - An 8-pin IC socket to house the tiny85 - A M12 button, which is fat but short - A regular PCB tact switch (secure it to the frame with glue) - Micro sliding switch for main power (see picture for the one used) - LED strip (WS2812 or APA102/104; choose your preference! Be cautious about the pitch, though; it needs to be approximately 16.5mm... I used APA102) - Wires and a soldering iron - Optionally, some white and black paint to cover the lens and prevent light from polluting the neighborhood. Start by painting the back of the lens with white paint, let it dry, then apply generous amounts of black paint.
