![]() ![]() Take a block of steel, say 2 1/2" square, 8" long. 3 readings per hour, 8 hours, so 24 sets of numbers. Let's assume the digital sundial needs to work for the sun apparently moving through 120 degrees, and we want readouts at 20 minute intervals. Mmm, would it be that difficult? Here's an idea, not needing all this new-fangled CNC or 3d printing gubbins With the light controllers mounted between the thin flat D shaped discs to form sandwiches for each line of pixels the sandwiches would be joined in a stack to form the "stick".įrankly I'd say that a sundial with a cast sculpted finger in bronze that casts a shadow on a clock face would be a far easier "digital sundial" to make. ![]() I'd see each of the layers as two half discs drilled to take wires or narrow flat leaves as indicated by the plan. Still a LOT of work but doable if one is so inclined. But if he makes the plan available an enlarged version so the wires and flat leaves are more "fat finger" friendly should be possible. Looking at the light passage layers in the video at 9:22 is what makes me think this way. And I'm sort of thinking that at the cusp between digits you'd see both sets of numbers for a few minutes.Īt the size shown? I think it would be overly fussy work for anyone that isn't a watch maker. Also it only works in 20 minute intervals. Note the one part is a rather nasty set of printed in place pins and leaves so as the sun projects through the openings it's shaped to let the light through or not to each pixel. People have been using the sun to tell the time since life began, but few ever expected that system to be worthy of an upgrade. Open topic for all opinions on how that sundial can be made at home without a plastic grower, Ehh. So if you are reading this you are on line There is a Wealth of knowledge here RE: casting, and machining. It can be a "grown" in place, well lets call it continual casting. Is that Sundial out of the capabilities of a Manual Machinist. What got me thinking to post here instead of the Digital side is. ![]() The time zone for this one is 10:00AM to what I think was 4:00PM. Looked like a really nice digital time shown on the wall. He grew the shape a slot at a time I think. It was a fun display of a person, just an average Joe stepping up. A sundial that when a point of light is shined at it and either it or the light moves in a linear line the light will be projected through the sundial at different holes or slots. This guy was super inventive, I haven't seen one yet. I would if I could afford it, far from my kinda money. It is about machining, they type many home shop guys are trying out.
