Description

A Sundial displaying the time inside its shadow, with actual digits ! There is a tiny bit of magic inside...
And it's an invention by Mojoptix.

No batteries, no motor, no electronics... It's all just a really super-fancy shadow show. The shape of the sundial has been mathematically designed to only let through the right sunrays at the right time/angle. This allows to display the actual time with sunlit digits inside the sundial's shadow.

The sundial displays time (with actual digits !!) from 10:00 until 16:00, updating every 20 minutes.
You can precisely adjust the displayed time simply by rotating the gnomon (the magic box that displays time). So you can even adjust for Daylight Saving Time.


Content of the DIY kit:
The kit comprises four 3D-printed elements, a small jar and four nuts and bolts to assemble the sundial.
Don't forget to choose the plastic color, and the part of the planet where you'd like to use the sundial:
-- Northen Hemishpere: choose "NORD // Northen"
-- Southern Hemishpere: choose "SUD // Southern"


Made by the Maker:
This can only be done with a 3D printer... and a lot of patience (it takes almost 35 hours to print everything).
So you'll most likely never see this sundial mass-produced and sold in a supermarket: it can only be crafted slowly, one at a time.
To ensure the best quality, I print the gnomon (the magical box that display the time) with 0.1mm layers, and the other elements with 0.2mm layers. Everything is printed with ABS plastic (the plastic used by LEGO), on my own 3D printers (a couple of Ultimaker 2).


For more details on this invention:
I made a video on my Youtube Channel describes the invention, design and crafting of this sundial. It even includes a timelapse showing the digital sundial during a full day.

Ce cadran solaire est vraiment une curiosité! Je suis extrêmement contente de cet achat. Cependant, je note 2 bémols: le délai de livraison (commandé début juillet et reçu début septembre, il ne faut pas être pressé, mais bon, ce n'est pas bien méchant...) et j'ai été prélevée 2 fois (là en revanche, même si j'ai été rapidement remboursée, le service etsy est décevant...)

This sundial is so amazing :). It was packed very well and shipped fairly quickly considering how backed up I know this shop is. My only suggestion would be to include some assembly instructions. Any logical person will figure it out, but the last screw was a bit trickier and instructions would have saved me a few minutes. Also, some tips on where to/how to install it would be nice too. It takes some trial and error to find the right direction/angle to get it to read the time correctly. But overall, a GENUIS product that is fun to show off! Love it!

This sundial is ingeniously designed. I'm still amazed that it works. It's not very practical for me, but it looked so cool I had to get it.
