Antikythera mechanism, ancient Greek mechanical device made of bronze and used to calculate and display information about astronomical phenomena. In my own version of the Antikythera mechanism (https://grabcad.com/library/mecanismo-de-antikythera-1) prior I assume that the lunar anomaly gearing had two different modules: one to the e5-k1 gearing (0,5 Module) and other to the k2-e6 gearing (near to ,55 Module). See all stories. Naturally the Freeths articles in 2006, 2008, and 2014 have been extremely enlightening and exciting. Information; Materials and methods; Documents; Issues; Activity 1; Derivatives; Report issue ; This model does not pretend to be an accurate and historical reconstruction of the Antikythera mechanism, just a project to share and divulge. I will post photos as I progress. Can you please direct me? Lego Antikythera Mechanism. The Antikythera mechanism (an ancient greek astronomical calculator) originally made of bronze, was recovered from the sea after 2000 years, over this time it had corroded and become a calcified lump. The Antikythera mechanism, one more mystery of the ancient world, is an ancient mechanical calculator (also described as the first known mechanical computer) designed to calculate astronomical positions. Best of luck, and I hope that things have calmed down enough for you to have a play with this again. My earliest orrery is now coming up for its 10th birthday and working just as well as the day I finished it. I had a good play with it this evening and was amazed at how close I was to actually getting it going, so a couple of hours of fiddling and this is the result: A bit clunky due to a couple of binding gears – easily fixed – and a few gears are still missing from the bottom of the machine, but the complicated bit is done. Just thought that I’d share a couple of photos of how my machine is coming along.

T he Antikythera Mechanism -The Designing and Building of a LEGO Version including designing and 3D printing the needed custom LEGO compatible gears.. Plan C Live: Economic Recovery from the … In the artificial world there is neither mass, inertia, force, friction, nor elastic or inelastic deflection. I'd love to do this! The Antikythera Mechanism used triangular teeth. My own reason was that that I think that, if the Antikythera Mechanism builder knew the modern gearing theory, surely he did choose it to his work. I’m starting to get excited now that the whole thing might actually work as planned! It was constructed between 150-200 BCE and was used to calculate the exact position of They became caught in a storm and were forced take shelter around the island’s main port of Potamós. It isn’t perfect. Learn more. But, in this version of mechanism, I eccentred the k1-k2 axles in radial direction. Hi Trixie, It was recovered in 1900-01 from the Antikythera wreck, but its complexity and significance were not understood until decades later. The second option is probably better engineering but takes up more space (not really a problem in the situation that we’re looking at though). I will be prototyping in plywood and intended to do the final version aluminum. registered on your site. It is more probably that it was used to provide a mechanical model or to a didactic use. Jun 9, 2013 - Download files and build them with your 3D printer, laser cutter, or CNC. Thingiverse is a universe of things. great work. Oh, and to answer your question, yes I do use a depthing tool to set up the centres. Plan C Live: From Invention to Innovation: Maker Incubators During Covid-19 . The planet gearing is to Colin Freeth’s proposed design, for no other reason really other than it builds up into a single very neat self contained unit with minimal gearing – it really is a beautiful design. How did you choose the size of each gear? I have prototyped the k1/k2, e5/e6 gear train and plan to prototype the inferior and superior planets next. I tracked it down and it was an error in my gearing spreadsheet – k2 should be 50 teeth. did you update google drive model ? Secondly, this ancient piece of machinery might have been the very same device mentioned by Cicero – which supposedly was crafted by the great Archimedes himself, and was taken as booty by Roman general … You’re more than welcome. Thanks for finding that, it probably would have gone unnoticed in the remake of the model that I’m doing. I’ve done quite a bit of work on a new version that will actually be manufacturable rather than just being a computer model. But… if someone had access to a 3D printer and would print me a copy pro bono, I might be motivated enough to clean it up. Any chance that you could put a copy of the STL files in the repo you have made? How did you determine/where did you source these values? You signed in with another tab or window. Thanks so much! The file “plate front v2.png” is taken from. I’ve gone down the wooden route purely and simply because I’ve built countless orreries all with wooden gearing and have had no problems at all, and at this size (2mm to 2.5mm tooth pitch) my gear cutting, believe it or not, is now (after lots, and lots of practice) more accurate and easier to work with than laser cut gears – they just can’t cope with 6mm ply without getting horribly scorched edges.

The Antikythera mechanism (/ ˌ æ n t ɪ k ɪ ˈ θ ɪər ə / AN-tə-kə-THEER-ə) is an ancient Greek hand-powered orrery, described as the first analogue computer, the oldest known example of such a device used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance. So how are the rest of you getting on – any news? Education . being the most ancient computer to be known so far. This is actually the mean value of the modules for all gears in the Mechanism. Later, I realize that the eccentric displacement could be made tangentially with the same effect and so the module of gearing could be the same to all four gears. They work, but aren’t great. From $7.95 Boombox Patent Print. Unfortunately, there are a few issues that would keep it from working well if 3D printed right now. Where are you based by the way? Cheers. So, on my machines the gears are interference fit onto the brass tubes with a little super glue, after which they are going nowhere. I’m pretty sure we’ve also found the same source for the telescoping brass tubing. Cheers, I made it in SketchUp using online photo references and specs. I have a design in mind so will just have to see how it pans out – can’t wait to be honest to see it start taking shape. Cheers, The Antikythera mechanism is an ancient Greek analog computer and orrery used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance. Figure 2. Complete Antikythera Mechanism Solidwork Files Total 50 MB There are two read me files inside with … But that won’t be done for probably a year – I’m going to start rework over the holidays and pick it up again over the summer. A very loose printable sketch of the two thousand year old, shipwrecked analog computer. My design will try to make as much of the mechanic as visible as possible. Axle K is modeled with a 1.00mm epicenter offset for k1 and k2. I always learn the hard way (Age related). By day, I’m an engineer in snowy Denver CO, and by night I cook, tinker, and enjoy the night downtown. Thanks for the info on how you mount the axles. I’ve put links to a coupe of photos of how I’m getting on if you want to have a peek. I noticed that you had a separate fixed gear for venus and the solar anomaly. Hi Trixie, It looks very similar in approach to how I am planning on doing it, though I’ll be using a laser cutter to make the gears since I lack the patience to hand cut them (which I’m very impressed with). Hi Trixie, I have also withdrawn the files and re-released them under a similar noncommercial license.
