- This video shows how to use an astrolabe to take a sighting of the sun, and determine the local time and true north using the sighting. You can make your own astrolabe, too! The astrolabes I show in the video are laser cut using the files at

I have been looking for a video like this for years to show my high school history class. This is very informational. EXCELLENT WORK
Great! Thanks. By the way, laser cutting plans mentioned in description also work on paper. You can have students print them out and pin them together.
@@drmichaelrobinson How did you learn this?
Why didn't I have u as a teacher 😂
@@drmichaelrobinson sir astrolabe major sun and star position also
A clear, concise explanation. Thank you very much for the video.
Midieval equivalent of a smart phone! Brilliant!
6:18 .... you use a pocketwatch just like I do!! Holy cow, I thought I was the only one alive who did that anymore! Btw, excellent modern astrolabe, especially the compensation for Earth's elliptical orbit...
Thanks! The SVG files are up on my github page if you want to make your own:

The Astrolabe is an amazing instrument. Thank you for a great explanation to what the Astrolabe can do.
I never have been more fascinated by this medieval tech tool. Nice video!
its 2000 years old and probably older than that
WOW, I would love to know the history of how they came up with such a complex piece of equipment. The "thinkers" of this world fascinate me. Love to all...Kim
Thank you, I appreciate that you took the time to prepare this
thank you for doing two readings , other videos are like "look how cool, and you can read various things with it"
GREAT VIDEO! . Whenever I think about a NASA engineer (from the Apollo mission) I think of a person that looks like this guy!
Apollo Mission ? Yes, in a Military Filmstudio.
Ancient people were so smart to invent and use things like this, without calculators or mathematical notation or accurate astronomical models
This WAS the calculator and mathematical notation and accurate astronomical model. So yeah, they already had that. They didn't make this WITHOUT those things. They made this WITH those things. They had to have those things first, before they could build this.
Also known as the Islamic World.
This thing rocks! As a Portuguese, it should be mandatory kids/teens have its use taught in History/ Geography classes.
Such an incredible description of this incredible tool!!!
Very interesting. Amazing how smart people were.
Wow I'm buying one Sir you blew my mind your explanation.. but the whole astrolabe itself is like 🤯 mind blowing who did all the math how long would that have taken so many questions.
Thank you Sir. This is a great explanation. Much appreciated.
Thank you! This was very informative!
That was so helpful to my understanding-thanks!
Love your video, wish you could the same but with a medieval planisphere.
Thought your lining up to the sun was very clear. Not sure whether it would have been really used to tell the time, would have been easier to do that by observing the Sun's direction and how high it was in the sky and the season.Much easier. But the other 1000 uses, as this was used to serve astrology.
hard to tell what you are pointing sometimes but still somewhat helpful.
That looks nice, if I ever get to use a printer I'll defenitely make one
Man, you are such a character. You seem somehow annoyed to about the position of the sun 🤣
This is excellent!
Thank you, sir!
Great video, dude!
Put giant glasses on this chap's face, and you've got Brains! FAB... 😁
Nicely done.
Thank you, I love you.
very informative. thank you
Great video!
Sir, the measurement of time is only 4 minutes off as it took 6 minutes to explain it to us. 👏👏👏👏
very helpful
Yooo it’s dude from big bang theory
Fascinating - thanks
Super. but I didn't understand how to use it as compass. The ruler points at 125 degree azimuth between east and south? And you said that it's north oriented compass?
Is it just me or is this guy secretly Leonard from The Big Bang Theory?
Where can I buy something like this?
Can you tell me where to buy this exact one?
Wow
If you sold assembled astrolabes on Etsy, you could make some money and make nerdy people like me very happy at holiday gift shopping time!
Hola soy al tercero que envio este mensaje aver quien lee primero y ojo lo aplica al esrra labio confuguracoon de astro lavio de 13meces de 28 dias y cera mas preciso o podria decir 100% preciso .
As una simulacion o un prototipo y me la envias gracias. Felicidades ya eres un ganador amen.❤❤❤❤❤
Does it work for any latitude?
nice job thanks
hi sir thank you for the information but sur i don't know how can is use the code to make my own ostrolab can you please show us how to use it and did it work for anny latitude ?
You can use this to find equinox correct ?
Thats mean that the earth is the centre and the sun move, the astrolab cant work on moving obgect
this is why i'm always late to work
I'd like to buy one if possible
Even better! You can make one yourself. Here are the plans for the instrument in the video: github.com/kb1dds/large_astrolabe
Camera work?
amazing
Amazing, there are more than 1000 uses with arabian astrolab
I'm so lost lol
Invest in a tripod.
astrolabe first time invented in india by mahendra suri 👍
You never once mentioned or give credit to Muslims who invented this tool during golden age of islam. It wasn’t “midevil” in their part of the worl!
Bro. Get over it. Not every video has to kiss your ass.
The astrolabe was from Ancient Greece. Dating back over 800 years from the golden age of Islam.. 😂
@@user-uk4gw6gp8bso where are the greek ones, most of the ones in museums have Arabic writing on them so we know where they came from
Doesn't mean Muslims made it. It's not Muslim they just adopted it
@@user-uk4gw6gp8b those were basic and had very limited features. The Islamic World is what truly enhanced the profile and festures of this colossal device.
Behold,,,,,The Flat Earth!!
