Wireless Lunar Phase Tracker

The Lunar phase tracker is a small, semi-portable device which allows you to gather critical information about the Moon. The device reports back parameters such as the visible illumination, the phase, moon rise and set times and more.
This device is essential for anyone who has an interest in science or astronomy and provides a great desktop office decoration and is certainly a conversation starter.
The project is fairly simple and requires an internet connected device such as an ESP32 however you can always adapt the code to work with a WiFi shield, Ethernet shield or any other internet connected device you may have. The Lunar Phase Tracker has been designed to work off Lithium-Polymer batteries and a very power efficient E-ink display which not only provides a wonderful screen to look at but also holds the last image even if the power goes off!”
