The Postcard Sundial
This solar chronometer is the little brother of the Big Compass Sundial. With a few cuts, this postcard-sized cut-out sheet becomes a fully functional classic horizontal sundial. It works with a foldable shadow triangle and can also show the time of the sun in the early morning as well as in the late evening hours.
- Dimensions of the built model: 12 x 9.5 x 2 cm
