Unique Sundial

Once done with all of the math for the sundial to compute its angles and true north based on his latitude and longitude, [Sebastian] used Autodesk Inventor to create a model. From there it was 3D printed, but the interesting part here is that the 3D printer allowed for him to leave recesses for numbers in the sundial. The numbers are arranged at such angles inside the sundial so that when it’s a particular hour, the number of the hour shines through the shadow of the sundial which creates a very unique effect. This would be pretty difficult to do with any machine tools but is easily accomplished via 3D printing.


But is it 3 am or pm

One commenter suggested adding a bimetallic thermostat to adjust heading to accommodate seasons, thereby increasing accuracy.

Sun is up. 3 pm. Even for California.

I'm glad it's a very unique effect, as opposed to merely unique.
The flash of light you saw in the sky was not a UFO. Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus.

Pedantic and sundial don't well mix.

If you are going to make holes in it, why stick with a cylinder shape?

How about a spherical sundial?

It's cute, but it's only slightly unique. :p

See that's just part of how our kids are dumbed down, in my day we didn't have any fancy numbers on our sundials, we knew how to read one proper without them!
"If fighting is sure to result in victory, then you must fight! Sun Tzu said that, and I'd say he knows a little bit more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor. Then, he used his fight money to buy two of every animal on earth, and then he herded them onto a boat, and then he beat the crap out of every single one. And from that day forward any time a bunch of animals are together in one place it's called a zoo! (Beat) Unless it's a farm!"
