Tadam! A Digital Sundial displaying the time inside its shadow, with actual digits! There's a bit of magic inside... No batteries, no motors, no electronics. It's just a really intricate shadow show.
The shape of the sundial is mathematically designed to let through the right sunrays at the right time/angle. This allows it to display the actual time with lit digits inside the sundial's shadow.
The sundial displays time (with actual digits!!) from 10:00 to 16:00, updating every 20 minutes. You can precisely adjust the displayed time simply by rotating the gnomon (the magic box that shows the time). You can even adjust for Daylight Saving Time.
You will also need:
- an empty jam jar
- 3x M6 screws, flat head, length = 20 mm
- 1x M6 screw, flat head, length = 50 mm
- 4x M6 nuts
- 4x M6 washers, outside diameter < 14 mm
