Hahaha It was the first thing that came to mind too! Although I think I should have the option of being able to change direction depending on the season of the year!.
I cannot describe you how I feel ... this came in my dream a few years back .... and I have been working on it...you pioneered it before me...congratulations ! Thank you for the video.
i had to watch that part 5 times now it had me laughing so much, definitely my new fave, i dunno if it is the accent or the alphabet pronunciation where he is but that was gold for me, lol
Hi Mojopitx, this is Mr. Cooley and his class. We love our sundials!!!! You made us very happy as we are learning about Mesopotamia and other ancient cultures who used sundials. You are super generous and we are very grateful. Thank you very much!!! You are the best, Mr. Cooley and his students :)
That's ace! Thanks for sharing the models and making the video. I've not come across OpenSCAD before either. I'm blown away by how clever and simple this is, you've got me thinking about other projects along similar lines. Thanks again!
This is absolutely brilliant (you are a genius)! When I read the headline I first thought about some Arduino inside. Then I began to guess about the tunnels, but did not believe myself because I thought, it requires too many tunnels. Then it was finally the tunnels if we take it in 20 min increments. I am not sure if I will print one, but I am very glad that you are so clever! Thank you so much for this feeling!
I have no words for how brilliant this is! Is this scalable? Have you ever thought of trying to make an installation out of this? Like a big semi-dome - maybe even a piece of patio/yard furniture (almost like a really cool - albeit heavy - umbrella)? I need to get on my CAD and chart this out. (Of course as a remix, citing you as the original inventor) absolutely brilliant! I’m subscribing and planning to binge-watch your other videos ASAP!
Very wonderful and amazing idea! I've always been fascinated by sundials stuff and I thing I'm going to reproduce your work for myself with my own 3d printer. Thank you to share it with all of us!
Brilliant idea. A large one of these would be an excellent piece of public art. The small one is exceptionally cool, too. Thank you for sharing! I think I'm going to print one today. Merci beaucoup!
I realise I'm (very) late to the party, but I just to have to say what a wonderful project this is. And also to thank you for explaining it so well in your excellent video and finally, to thank you for making the files available at no cost to all. Thanks again.
Astounding. I kept waiting for the section in the video where the circuit board and liquid crystal screens are installed. A dual format sundial with no moving parts. Amazing. I hope to see better footage of the 'black box' to get a sense of the intricacy of the cavities.
This is really fascinating. I have one question though, would it account for seasonal changes? I mean, the angle at which the sun light hits us changes from season to season right? So, I am just wondering that if we calibrated it in summer, would it tell the correct time in winters as well?
I wish to take nothing away from this awesome display of intellect so I will kindly tell you a little story. When my wife was a child she was on a television program and was asked if she would like to visit a penguin at the North Pole? Her response was, "Ms. Vonnie, penguins don't live at the North Pole." Ms. Vonnie told both my future wife and the audience that she was wrong. Great video, thank you for producing it. Please place this comment in the bin marked "Gushing Praise" with the rest of the comments.
+Tainer Waynes Maybe he confused the English word penguin with the French word pingouin, which means auk (a bird similar to a penguin which lives in the Northern Hemisphere.) The French word for penguin is actually manchot. :)
+Angela Brett as if the drawing wasn't clear enough :)) and the French word for cow is vache. So what are those in Switzerland in this case ?? Let's face it... it's just dumb to say there are penguins at the north pole. :)))))
I know i'm super late to the party but I've just tried printing the model and noticed that while the 0 minute digit doesn't change at all and is reflective of that by not having any bridges in it's 'slots' since no light needs to be blocked, the 1 hour digit does have some redundant bridges, my guess is since the code might actually be programmed to calculate a transition for hours where 1 isn't required like 9:00, but it isn't actually used? In any case I wonder if it's a bug in the code and am planning to take a deeper dive into the .scad file later. Any chance anyone has also noticed it and took a look at it before?
Idea: Put degree marks on the hinge 3D model with a matching line marking on the sundial arm so that you don't need a protractor while adjusting for latitude. It could also come marked with latitudes for famous cities. If I made one for myself I would just mark it for my own city. What a wonderful project. I have never seen such a mix of software and making a physical thing.
This design could be updated as to show the date too based on latitude of the sun. I can see that in periods in when the time is changing, it could get confusing to read. If the dial was made bigger, I would suspect this would be less of a problem.
Very cool and amusing. Rocket Surgery, Interweb, maybe a week long, magical black box & Vegemite. Ha ha. Had to rewind a few moments. Love the humour and fun that you have with this! Definitely gives me Mojo! Must be a cynical engineer!
Awesome first video... very impressed by both the concept and the elegant algorithmic design of the "magic black box" itself. I don't know a great deal about in 3D printing, but I wonder if it's possible to use a multi-material printer to have the tunnels printed using photo-optic (aka "light pipe") plastic to increase the brightness of the pixels and make the whole structure less delicate? Might increase the printing time a totally impractical amount though...
I have a stupid question. If you printed this say 4 times larger could you increase the "time resolution" to say every 5 min? Or even bigger? How big would it have to be to get to say 1 min resolution?
This is soo cool. Does the pattern have to be reversed in the southern hemisphere? Is it theoretically possible to design one with higher resolution, like 10 minute intervals? 5 Minute?
Hello ! Really a nice invention there ! I love it ! But... I don't want to be impolite, I just want to check some few things with your analogical sun dial : due to the variation of the sun "height" during the year, we would have to change the angle of the sun dial to still have the right time (so +/- 23° to latitude to follow the Sun's travel, due to the obliquity of planet Earth and so on) wouldn't we ? Or is it conceived with this factor in mind ?
I really really love the French accent. This video went straight to my favourites list :) I wonder whether a scaled-down version would work? That would considerably cut the printing time. I'm going to try and make one on my 3D printer as a test.
If you scale the sundial 20x without scaling its tunnels, would you have enough "resolution" to display each minute? I assume your 20 minute restriction is limited by how dense your tunnels are.
Awesome! im printing on of these for myself right now :) Was curious on if you have tried, or if you have any idea if a larger scale one would work just as well. (or would it need adjusting of the "swiss cheese")
This is awesome, too bad that you didn't really explain the Swiss cheese structure a bit. Maybe you can create a separate video on the exact design of it?
+pablo321123 not really, basically he just explained a single pixel, so everyone gets the idea and that's okay. But how to design the whole Swiss cheese wasn't really covered.
+flow2fly he explained the software and the code used. Do you want him to write it for you? Oh wait, he already did that as well! What more do you want, hint nobody can do the understanding for you.
+pablo321123 for example to show a cut through the Swiss cheese so one could see from the side how the light passes for different angles. I mean for a single whole it's easy to grasp, that's nicely explained. But I am especially interested how he managed to have so many wholes and still block the light of all the wrong times and let only the correct one pass through. That's not as trivial as you want to make me believe.
Hi there Mojoptix, hope you`re fine,!!! let me tell you amazing job!! standing ovation really!!!! this Sun clock its exceletn, but as much i was searching for the Public opensource file i couldn´t reach it!! Please send me a link to the files!! reagrds!! and keep it on!
@Mojoptix What if instead of the light passing through the original 1 slit, if you just made it a double slit, like the Quantum Physics Basic explanation on what quantum physics is, applied that to this clock and just made every single slit doubled, in all directions patterns, would it make a sundial that also shows each minute and second as well? Hmmmmm... I wonder if its possible..
Hello, Would it be possible to make this Sundial in paper, or half-pipe PVC plus a flat plate, below? Would you get me a pdf file to print and cut? =) Congratulations on the beautiful work!
How does it work during different times of the year, when the sun is at different angles from the start? How does it work at the equator, where at noon the sun is directly above you? I'm honestly curious.
I'm curious about the ratio of the present size to the level of resolution of the time displayed. That is to say IF THE BODY IS BIGGER CAN I GET SINGLE DIGIT (MINUTE) INCREMENTS OR AT LEAST 1/10 HR (6 MINUTE) RESOLUTION?? please excuse shouting I'm extremely myopic and I don't have a LOWER CASE CAP FONT on this system. (ease of reading and OCD explaining) Thanks. Wonderful presentation. Would this work in Vertical Orientation as is, or would I have to use the same adaptation I learned 30+ years ago for Sun Catcher Vertical Dials?
Yes! It comes down to the ratio of the 3D printed volume to the printer resolution. So bigger gnomons shoud indeed allow for finer time resolutions. However there is a fundamental limit at about 4 minutes, due to the non-zero size of the sun in the sky (0.5 degrees of arc). With this sundial, the orientation of the surface catching the shadow is not really important. So vertical wall work just as well. You'll just need to hold the gnomon from the other end, to make sure it is still pointing toward the North (for example by using the Southern-Hemisphere version, if you're in the Northen Hemisphere).
Late to the party here. That's cool but for bonus credits, include months! Using the same idea with parallax masking but vertically on the stick you could get the months or the choice of months that it could be depending on how high in the sky the sun is. Would be curious if anyone can get this working properly.
My favourite part began at 12"35"" when Monsieur says"a whole bunch of pènis" while carefully adjusting the angle :) .......I'm ordering two units right away! Seriously though, sir; what brilliant insight.
Did anyone else notice that at 13:40, the time on the sundial is also 13:40 ?
That would make sense, after all it's a kind of clock...
OH WAIT!
If you are that detail oriented, you should work for cia 😂
This should be produced in huge and put on a public place!
+Jens Leinenbach ☻oh, YEAHhhhhh!! ( :^D
+Jens Leinenbach I thought the same thing! Absolutely great!
Hahaha It was the first thing that came to mind too! Although I think I should have the option of being able to change direction depending on the season of the year!.
It would serve well as a monument for a university.
Then people would it's 12.40 when it's actually 12.59
I cannot describe you how I feel ... this came in my dream a few years back .... and I have been working on it...you pioneered it before me...congratulations ! Thank you for the video.
Wait ... did you just pronounce WWW "woof woof woof"? This is my new favorite channel!!! Rock on Julldozer :))
i had to watch that part 5 times now it had me laughing so much, definitely my new fave, i dunno if it is the accent or the alphabet pronunciation where he is but that was gold for me, lol
Please make more videos.. I love this .. The detail and simplicity of your instruction was simply amazing !!
I printed mine with my new Bambu Labs X1 Carbon. The black box only took 4hr 34 min. It came out very nice. Thanks for a nice project!
Hi Mojopitx, this is Mr. Cooley and his class. We love our sundials!!!!
You made us very happy as we are learning about Mesopotamia and other ancient cultures who used sundials. You are super generous and we are very grateful.
Thank you very much!!! You are the best, Mr. Cooley and his students :)
Pity the blog and the video series weren't continued! So unique and well made!
That's ace! Thanks for sharing the models and making the video. I've not come across OpenSCAD before either. I'm blown away by how clever and simple this is, you've got me thinking about other projects along similar lines. Thanks again!

Very cool and original. This looks like a perfect New Years project. Thank you for sharing!
Says: "Just a few lines", scrolls through thousand lines of code...
This project blew my mind, it is so fantastic!
I have no words for how brilliant this is! Is this scalable? Have you ever thought of trying to make an installation out of this?

Love it! Great design, product and presentation! And a lot fun too!
Pure Genius........totally blown away by this project.
Awesome thing and great ingenuity. Thanks for sharing. Regards from Czech Rep.
I have been waiting for your next project for one year man, you got to do it real soon now.
make a video explaining the logic behind your script. that is the most interesting thing here
You make the whole design process look easy...Thank you so much for this wonderful video!!
Brilliant! I watched your video years ago and now that I have a 3d printer, I printed my own solar clock and it works great! thanks!
This is one of the best project videos I have ever seen!!!!!!
Possibly the best use of Vegemite ever conceived! Great video, very well put together - as is the sundial. Thanks. :)
thanks for taking the time and for sharing!impressive design!
Absolutely incredible! Looking forward to more such projects =)
Very wonderful and amazing idea! I've always been fascinated by sundials stuff and I thing I'm going to reproduce your work for myself with my own 3d printer. Thank you to share it with all of us!
Brilliant idea. A large one of these would be an excellent piece of public art. The small one is exceptionally cool, too. Thank you for sharing! I think I'm going to print one today. Merci beaucoup!
You are amazing. This is inspiring. I imagine 3D printing is the holy grail of heatsink design.
I realise I'm (very) late to the party, but I just to have to say what a wonderful project this is. And also to thank you for explaining it so well in your excellent video and finally, to thank you for making the files available at no cost to all. Thanks again.
Amazing creativity and a really well done video! This is a great explanation of the conceptual process. Brilliant!
I got one from my brother today!!!! Can't wait to get it together & out in the sun. Thanks for the video!!!
Greetings from South Africa. Thank you for the lovely video upload.. ;-)
Astounding. I kept waiting for the section in the video where the circuit board and liquid crystal screens are installed.
A dual format sundial with no moving parts. Amazing.
I hope to see better footage of the 'black box' to get a sense of the intricacy of the cavities.
So much effort put into this and the video! Good job sir! I wonder how complex it will be for the sun dial to display time by the minute.
This is really fascinating.
I have one question though, would it account for seasonal changes? I mean, the angle at which the sun light hits us changes from season to season right? So, I am just wondering that if we calibrated it in summer, would it tell the correct time in winters as well?
Wow!! I love it! I'll definitely build this once I get my 3D printer. Cheers for that! And a big Thankyou for making it open source for us all. :)
If you tell your sundial story then it sounds so obvious. But getting that idea in your head. Love this one!😃
This is freaking awesome.
I wish to take nothing away from this awesome display of intellect so I will kindly tell you a little story. When my wife was a child she was on a television program and was asked if she would like to visit a penguin at the North Pole? Her response was, "Ms. Vonnie, penguins don't live at the North Pole."

Dude.. there are no penguins at the North Pole ;) Nice build, though
+Tainer Waynes Maybe he confused the English word penguin with the French word pingouin, which means auk (a bird similar to a penguin which lives in the Northern Hemisphere.) The French word for penguin is actually manchot. :)

+Tainer Waynes Well, he said that he isn't any rocket surgeon...
+Findecanor That one cracked me up. I'm going to assume it was intentional, though. He's one smart cookie!
+TheGadgetPanda I'm guessing the penguin one was also intentional.
Recently printed this on my AnkerMake M5 with a .15mm resolution - came out dope, works perfectly!
The amaze moment is at 13:20. Love that it's weighted down with nails.
I know i'm super late to the party but I've just tried printing the model and noticed that while the 0 minute digit doesn't change at all and is reflective of that by not having any bridges in it's 'slots' since no light needs to be blocked, the 1 hour digit does have some redundant bridges, my guess is since the code might actually be programmed to calculate a transition for hours where 1 isn't required like 9:00, but it isn't actually used?

So then did you make one for yourself?
"OK, Kids, let's build a hovercraft! All you need are two rubber bands, some mayonnaise, and a hovercraft building machine."
My god.. thats some serious thinking outside the box to invent such a wonderful idea!
Seriously???? 😲😲... This is amazing!!!! How would you come up with such idea? I am speechless.. Thanks for sharing.
I want to cast this in bronze or aluminum. I may have to scale it up to get the metal to flow to all the parts.
This design could be updated as to show the date too based on latitude of the sun. I can see that in periods in when the time is changing, it could get confusing to read. If the dial was made bigger, I would suspect this would be less of a problem.
I love that he used the phrase "rocket surgery"!
Very imaginative and it is great to see OpenSCAD used for something it was made to do
I love your video lab cartoon effect, how did you do that?
Very cool and amusing. Rocket Surgery, Interweb, maybe a week long, magical black box & Vegemite. Ha ha. Had to rewind a few moments. Love the humour and fun that you have with this!
Definitely gives me Mojo! Must be a cynical engineer!

I have a stupid question. If you printed this say 4 times larger could you increase the "time resolution" to say every 5 min? Or even bigger? How big would it have to be to get to say 1 min resolution?
Awesome video & lmao "it's really not rocket surgery" at 5:00
I'm printing it now. I hope it works. My printer is Ender3 pro and has printed many hings over the last year. hanks!
This is ridiculously great :) Will print this soon! Subscribed.
Honestly this is one of the coolest things on YT just a shame I live in the UK, It would only work for the 3 days a year we see the Sun.
Hard to surprise me after the Digital Sundial! I'm kidding! This invention is as brilliant!
Thats an astonishing design, simple it ain't, it's a work of mathematical supremacy.
Love your creative 'workshop' back drop too
great man, you are awesome, thanks to tell us how to bring your idea into life....
This is soo cool.
Does the pattern have to be reversed in the southern hemisphere?
Is it theoretically possible to design one with higher resolution, like 10 minute intervals? 5 Minute?
awesome channel! thanks for your inventions!
Great Video! Very inspiring project.
I'm interested in the music you've put in the background. What song is it? I really liked it.
th-cam.com/video/B9iKMuCe33Q/w-d-xo.html
Saw this thing in action today for the first time at the Franklin Institute. Mind blown, to the second or 3rd power.
Hello ! Really a nice invention there ! I love it !
But... I don't want to be impolite, I just want to check some few things with your analogical sun dial :
due to the variation of the sun "height" during the year, we would have to change the angle of the sun dial to still have the right time (so +/- 23° to latitude to follow the Sun's travel, due to the obliquity of planet Earth and so on) wouldn't we ? Or is it conceived with this factor in mind ?

Extremely cool project. Thanks for doing this!
If you scale the sundial 20x without scaling its tunnels, would you have enough "resolution" to display each minute? I assume your 20 minute restriction is limited by how dense your tunnels are.
How did you pick 20 minutes as the interval? How large a gnomon would you need to be able to do 15 minutes or even 10?
Awesome! im printing on of these for myself right now :) Was curious on if you have tried, or if you have any idea if a larger scale one would work just as well. (or would it need adjusting of the "swiss cheese")
This is awesome, too bad that you didn't really explain the Swiss cheese structure a bit. Maybe you can create a separate video on the exact design of it?
+flow2fly did you not watch the video? He explained it in depth.
+pablo321123 not really, basically he just explained a single pixel, so everyone gets the idea and that's okay. But how to design the whole Swiss cheese wasn't really covered.
+flow2fly One pixel at a time (subtractive design, despite using an additive manufacturing process!)
+flow2fly he explained the software and the code used. Do you want him to write it for you? Oh wait, he already did that as well! What more do you want, hint nobody can do the understanding for you.

Quick jump to 13:04 to see it in action.
Hi there Mojoptix, hope you`re fine,!!! let me tell you
amazing job!! standing ovation really!!!! this Sun clock its exceletn,
but as much i was searching for the Public opensource file i couldn´t reach it!!
Please send me a link to the files!!
reagrds!! and keep it on!
A giant one of these made out of stone in a park would be pretty awesome.
This is what happens when you study only math and computer science, but not biology and geography. Penguins at the North pole! 4:20
Hey, it's 4:20, the penguins need a good vacation spot to smoke .
@Mojoptix What if instead of the light passing through the original 1 slit, if you just made it a double slit, like the Quantum Physics Basic explanation on what quantum physics is, applied that to this clock and just made every single slit doubled, in all directions patterns, would it make a sundial that also shows each minute and second as well? Hmmmmm... I wonder if its possible..
How long did it take to print out all Northern Hemisphere components using the Ultimaker 3d Printer?
Beautiful! What a brilliant invention!
Brilliant! Thanks for this design.
so basically to get fine tuned starting time you still need to check the time from a clock and then adjust sundial accordingly?
When is ep 2? ep 1 was awesome!
This is incredible and inspiring! Thank you!
pinguin at the north pole? never heard about that.
This is absolutely genius. You are a very smart man
Awesome Solar Digital Clock!
Hello,
Would it be possible to make this Sundial in paper, or half-pipe PVC plus a flat plate, below?
Would you get me a pdf file to print and cut? =)
Congratulations on the beautiful work!
How does it work during different times of the year, when the sun is at different angles from the start? How does it work at the equator, where at noon the sun is directly above you? I'm honestly curious.
Mind blowing! but... Why a glass jar? Why didn't you design a proper base for this?
Wow. This is very impressive. Well done.
whoa! so cool, i guess the modeling part with codeing is not that easy as you did it, Nice video!
I'm curious about the ratio of the present size to the level of resolution of the time displayed. That is to say IF THE BODY IS BIGGER CAN I GET SINGLE DIGIT (MINUTE) INCREMENTS OR AT LEAST 1/10 HR (6 MINUTE) RESOLUTION?? please excuse shouting I'm extremely myopic and I don't have a LOWER CASE CAP FONT on this system. (ease of reading and OCD explaining)
Thanks. Wonderful presentation.
Would this work in Vertical Orientation as is, or would I have to use the same adaptation I learned 30+ years ago for Sun Catcher Vertical Dials?
Yes! It comes down to the ratio of the 3D printed volume to the printer resolution. So bigger gnomons shoud indeed allow for finer time resolutions. However there is a fundamental limit at about 4 minutes, due to the non-zero size of the sun in the sky (0.5 degrees of arc).
With this sundial, the orientation of the surface catching the shadow is not really important. So vertical wall work just as well. You'll just need to hold the gnomon from the other end, to make sure it is still pointing toward the North (for example by using the Southern-Hemisphere version, if you're in the Northen Hemisphere).
@@Mojoptix can i scaled down but keep 20 minutes interval? ...
i mean in default file thingverse.. its to big for me
Merci pour le cadran solaire je vais essayé d'en imprimer un dès maintenant
you my friend will become a big youtuber...great video
I love your "cartoon" style lab what effects did you use for that - seriously cool!
Late to the party here. That's cool but for bonus credits, include months! Using the same idea with parallax masking but vertically on the stick you could get the months or the choice of months that it could be depending on how high in the sky the sun is. Would be curious if anyone can get this working properly.
Great idea!
My favourite part began at 12"35"" when Monsieur says"a whole bunch of pènis" while carefully adjusting the angle :) .......I'm ordering two units right away! Seriously though, sir; what brilliant insight.
