The new year means new calendars. This project shows off why an e-ink display makes a great calendar. The clean, crisp and highly legable design draws inspiration from Portal. Because its low powered 4 AAAA batteries should last the whole year. See the full build from Wuspy on GitHub:
This project was inspired by Reddit user u/feefifofeddit who made a prototype of a Raspberry Pi-powered Portal calendar. Unfortunately the display they used has been discontinued, and I wanted a battery powered and wall mountable version, so I designed my own based on the ESP32 platform with the goal of being as low-power and game accurate as possible.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
