Digital Sundial: a complex array of thin – Diy Craft Videos









 

Digital Sundial: a complex array of thinly layered microlouvers allows the control of transmitted sunlight depending on angle. Time is read by looking at the reflection of the filter in the bottom mirror. 11:30 AM to 2:00 PM shown here in 15 seconds of time lapse- note the movement of the shadow cast by the sun as the Earth turns underneath during this 2.5 hour interval. Astonishing engineering. ➡️ Follow the link in my profile for info on where to buy a digital sundial and other amazing items featured here on @physicsfun #astronomy #physics #sundial #digitalsundial #physicstoy #sun #equationoftime #gnomon #amazing #astonishing #science #scienceisawesome #timelapse
