Digital Sundial with Wall Mount and Table Stand

thingiverse

Digital sundial with single/double hour digit in the center and dots mimicking the minute arm of an analogue clock. For an animation/simulation (animated and rendered in Blender) of the sundial, see this video: https://youtu.be/3QH63sAIJxo. The technical solution is strongly inspired by Digital Sundial by Mojoptix https://www.thingiverse.com/thing:1068443. Apart from the obviously different form, these are the main differences: * The pixels are rotated 90 degrees making the sundial more appropriate for wall mounting and larger latitudes. * By spatially separating the pixels showing minutes a finer time granularity can be achieved - ten minute dots work surprisingly well. * The code is easily configurable to have the sundial made for the specific location and orientation. * There are mounting possibilities for mounting the sundial on a wall or placing it on a table stand. For a table mount, one wants to read the shadow from the north. To do this, the sun dial core must be designed with the reverse angular direction of the sun. A variable in the SCAD script achieves this. For the southern hemisphere, it's the opposite; The table stand variant can be wall mounted and the wall mount version can be used with the table stand - but the best solution is to configure the SCAD file with the sun path of the specific location, regardless of where on earth you live. The uploaded sundial core is calculated for a farm in Austria (Unteramt), with the sundial facing straight south at coordinates 48°N, 15°E. This version will work well for most locations.
