Remember me

Since we as a family had issues to keep periodic tasks in mind, I created a simple "remember me". Or may I say a "remember us"?

Every big button can represent one tasks which is simply written with edding on a short strip of slim clear tape, so it can be replaced without any residue.

The housing is opaque, the buttons are translucent.

How does it work?
With some code I am now able to set up tasks by defining it's frequency. The minimum is 1 day, the maximum is 10 weeks. When a task needs to be done again, the light behind the buttons goes on. After completing the task you press the button so its light turns off and the cycle starts again. Straight foreward I guess.
