THIS AWESOMELY 」TINY GAMING CONSOLE WORLD'S SMALLEST ATtiny85 Game Console Watch ...Play Games, Check time, Date and set alarm clock, The high-performance, low-power Microchip 8-bit AVR RISC-based Microcontroller Completely 100% Solderless Project

# Features

- Button 1: Display on clock mode or set hour/minutes
- Button 2: switch through clock, led on, menu mode (set hours), menu mode (set minutes)
- time accurency: about 2sec in 1hour
- lifetime: above 750 days ( 150 mAh CR1620 coin battery)


When Attiny85 and OLED turned on, will consume 6 mA.
so to make the watch run over 1 year, I'm using the ATtiny85 sleep mode (power saving ),
when the watch is not in use. checked with my cheap meter, it is 0.1 uA if disable all the function. But we still need WDT for time keeping, after enable WDT, it is 4 uA. Assume ATtiny85 and OLED automatically sleep after 5 seconds and a Normal Person views his watch 12 times a day in average, the watch will consume about 0.2 mAh per day. ((0.004 mA * 24 hours) + (6 mA * (5 / 60 / 60) hours * 12)) in total is a150 mAh CR1620 battery can run 750 days.
