I'm hoping it will last the whole day, have cool animated visuals, and be pretty to look at. + +## Desired Features and Goals +* 128x32 OLED monochrome display +* 128kb upgradable external EEPROM for images and short videos +* Fancy graphics, display images and videos that can overlay time with inverting filter +* Battery that lasts at least a day +* USB-C charging (may switch to micro-usb depending on IC prices/availability) +* Display the time + +## Parts +* Microcontroller: Any ATmega chip with TWI/I2C I can get my hands on +* Display: Waveshare 128x32 0.91inch OLED display +* RTC clock: PCF85063A +* EEPROM: BR24T128-W +* Battery Management: TBD + + +## Why +This project is to help me learn how to develop for AVR without Arduino libraries, read datasheets faster, and to prove I can solder small SMD components. It will be my first physical project where I design my own PCB, which has been something I've wanted to do for a long time. + |
