Byzantine Sundial-Calendar '1000 Hrs' Mega Edit

It's been a year like no other folks, so its defintely time for a chill out vid. Do please enjoy this '1000 hours' style mega edit of the Byzantine Sundial Calendar project.

Without doubt, I have never felt more relaxed than watching this 27 minutes sail by.

Thank you for tuning in, have a very Merry Christmas, and a Happy New Year, and I'll catch you all in 2021.

Cheers,
Chris.

Build info: The build is based on the sundial-calendar artefact currently located in the London Science Museum (https://www.sciencemuseum.org.uk/). The original artefact is currently regarded as the second oldest geared mechanism on the historical record, loosely dated to around 500AD.

As the name suggests, it's a combination portable sundial and lunar calendar mechanism. In addition to being a portable sundial, it computes the current age and phase of the moon, the position of the sun and moon in the zodiac, as well as the current date. I've extended the original design to include a Lunar Node display, according to the research of the engineering historian Michael Wright. This transforms the device from a simple calendar into a very effective eclipse prediction machine. It also makes it a great tool to help visualise the celestial mechanics behind an eclipse.
