raspberry pie Electronic ink calendars are nothing new, but this calendar design created by a manufacturer called Speedyg0nz is excellent.Not only Raspberry Pi e-ink calendar Connect to Google Calendar for updates, but it is also completely portable and has a built-in battery.
It uses a Sugar 2 A battery specially designed for Raspberry Pi Zero. The battery is connected to the GPIO, but still has full access to the pins and can be stacked with other HATs. It has a built-in RTC module, so the Pi can be programmed to turn on only when necessary. Google Calendar data is downloaded once a day and output from Waveshare to a 12.48-inch three-color electronic ink display.
Speedyg0nz has developed a custom Python script to extract calendar events from a given Google calendar. Then, this script formats the data into a predetermined layout, which is updated on the electronic ink display. Since the display is electronic ink, the calendar will remain visible, so the Pi can be turned off to save power.
According to Speedyg0nz, this configuration will last for a while before the calendar needs to be charged. During the test, the PiSugar2 battery can be used for about 3-4 weeks on a single charge. To keep an eye on the battery level, a small battery indicator has been added to the upper corner of the calendar display.
this The best Raspberry Pi project You can make it at home, Speedyg0nz kindly shared a complete build guide GitHub For anyone interested in recreating it. Check it out to understand more closely how it fits together and explore the source code.
