Make this project in time for Halloween and never have to retire it!
From allie.fauer on Instructables:
Any die-hard Harry Potter fan will remember Neville Longbottom’s Remembrall. This object is described as a small, glass ball that fills with red smoke when its owner has forgotten something. Unfortunately, the Remembrall doesn’t inform the owner about what they have forgotten, rendering the item fairly useless.
Because I seem to have a knack for creating useless things, I decided to create a Remembrall that ACTUALLY WORKS!!!!! This Internet Connected Remembrall functions alongside Todoist, which is a web and mobile to-do list application. After gathering the owner’s data, the Remembrall turns red if due dates of uncompleted tasks have passed. While I will admit that my Remembrall isn’t quite as useless as Neville’s, it is sure to leave it’s owner in a state of panic as they try to figure out what they have forgotten (or at least I hope it does!).
