So I want a physical notification when I get a new snail mail. I went through the local flea market and picked up a nice candle lamp for $1.
I tried fitting it with LEDs to make a visual notification, but it seemed too easy. Besides, I want the notification to be as little technology reminding as possible. So I came up with the idea that it should rotate when a new mail has arrived. It took a lot of work and hot glue, but in the end it turned out great.
To make a stepper motor, control board and a D1 Mini fit in the base, I ended up using enough hot glue to basically make the whole base water proof.
