This a reconstruction made with the free information on the internet (since the scientists data are well kept on the museums). Cheers, Sorry for the late response – been a bit tied up the last few days. Jun 9, 2013 - Download files and build them with your 3D printer, laser cutter, or CNC. There are a few issues that would keep it from working if you 3D printed this, and a few more issues that make it not completely authentic to the original Mechanism. No judgement at all for fudging it a bit! From $7.95 Apple Computer Patent Print. 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. If nothing happens, download Xcode and try again. They became caught in a storm and were forced take shelter around the island’s main port of Potamós. Wright, the leading model maker of Antikythera Mechanism, justly points out that a computer-generated 3D image does not have the same persuasive power as a physical model. The Antikythera mechanism is an ancient Greek analogue computer used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance. From $7.95 Antikythera Mechanism Print. I’m keeping everything crossed… Jun 9, 2013 - Download files and build them with your 3D printer, laser cutter, or CNC. Thx. I’d be willing to help with the physical printing if you’re interested in getting this working 100%, Would be an amazing option for intellectually minded people for Christmas. Dave, that’s fantastic! Titancraft Lets You Create Custom Creatures For 3D Printing. Thank you! Please login to your account first; Need help? Cheers, The Antikythera Mechanism originally had at least 30 meshing bronze gears, and up to 37 gear wheels that helped the device keep track of astronomical bodies like Mars, the Sun, and the Moon. I tracked it down and it was an error in my gearing spreadsheet – k2 should be 50 teeth. The general actual module of gearing is near 0,5 mm which is (surprisingly) a big coincidence, since there is not possible that the ancient Greeks did know the Module System (metric standards based, created circa 1900 AD). Students are gradually introduced into the 3D printing technology, its application and potential and are assigned a challenging collaborative project in which they have to study, analyse, design and build, using the 3D printer of their school, an operational model of a renown ancient artefact, the so-called Antikythera Mechanism. I’m Scott. 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. Although the manufacturing techniques and mathematical solutions incorporated into the actual machine are the core interest, I am as interested in the actual results of what the mechanism meant to the designers and users. It was extremely accurate as well, correctly reporting subtle variations in the lunar orbit, for example. Dave. I haven’t figured out how best to do that yet. Best of luck, and I hope that things have calmed down enough for you to have a play with this again. did you update google drive model ? just found this thread. The sizing of the gears was pretty crude – I took the number of teeth for each gear and multiplied it by the mean module for all gears (0.47, from the ISAW paper). 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. 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. I can’t remember if I shared this, but below is a YouTube link to a film of the whole planet mechanism working. But the entering gears (a1 and b1 as the standard denomination marks) had 0,6 Module (which is 0,6 mm x pi diameter pitch). download the GitHub extension for Visual Studio, http://kirolab.blogspot.com.es/2016/10/interpretacion-del-mecanismo-de.html. I’m pretty sure we’ve also found the same source for the telescoping brass tubing. It looks like your final machine should be quite something when done. The Antikythera Mechanism used a combination of adhesives, pins, and friction fits as fasteners. 3D Printer Patent Print. If you don’t mind me asking, what are you using to anchor the axles with only one end mounted, while still letting them spin? It’s a wonder the Antikythera mechanism was discovered at all. The other way to do it is to fit the gear onto the rod and have 3 or 4mm of the rod protruding above the gear and then simply solder a 2mm sleave onto this protrusion to stop the gear from escaping again. Are you working on your own model? I plan to cut most of the device from aluminum or stainless steel, with stainless arbors and roller bearings. But the planetary pin placement can be found in appendices of the ISAW paper. Ahhh, CAD… wish I had the time to learn it properly… all my designs are in note book form, or designed directly onto the wood and then patterns taken from that once I’m happy that everything works. It is now thought to have been built about 100 … I have 3D printed a working model of the Antikythera Mechanism. Dave. Gear k1 is modeled with the distance from the center of the gear to the center of the pin as 8.00mm. Here are the places where the model differs from the Antikythera Mechanism. I too am having a crack at building this amazing contraption but I’ve opted for hand cut wooden gearing as that’s what I’m used to doing (I have been known to build the odd orrery or two). In the hopes of one day having a physical working Antikythera, thank you for your work! The complete gearing for the moon is large and complicated, but if you just want the part at the top that makes it spin on its axis, you could make it pretty easily. The plan is to get a version that can be laser cut from sheets of wood, and release the files to the public. Publisher: greekgears.com. 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. The file “plate front v2.png” is taken from. Axle K is modeled with a 1.00mm epicenter offset for k1 and k2. Questions of material strength and wear properties are excluded. Hello, i also live in and work at night in Denver. The heavy corrosion of the mechanism makes me think the difference isn’t all that meaningful. Hi Scott, Doing Experimental Science at Home. I’m planning to have this next version be laser cut from sheets of wood rather than 3D printed, so the processes from your model are actually very applicable! File: ZIP, 48.49 MB. I built a home made one which works brilliantly. Any chance that you could put a copy of the STL files in the repo you have made? The Antikythera Mechanism used triangular teeth. Fix Our Planet, Part 4: Reinventing a Material World. Education . I just happened across your page by chance tonight. I wonder if you can help me a little. Pingback: Human skeleton found on shipwreck that held mysterious Antikythera Mechanism - TECHNICAL FORUM, Pingback: Human skeleton found on shipwreck that held mysterious Antikythera Mechanism | NUTesla | The Informant, Pingback: Human skeleton found on shipwreck that held mysterious Antikythera Mechanism – Scott Rojas, Pingback: Human skeleton found on shipwreck that held mysterious Antikythera Mechanism | Headlines Today. If you don’t mind me asking, how did you anchor the ends of each axle, so that the gears can rotate together and still stay firmly on axis? So, it’s impossible that the original mechanism was used to calculate real cosmic events. “Calendars with Olympiad and Eclipse Prediction on the Antikythera Mechanism: Supplementary Notes”, and slightly edited by me. Update June 2015: I’m revisiting this project to finally get it to a version where it can be manufactured at home. Calculating axle distances = Ad=0,5M(Z1+Z2). The front of the Antikythera Mechanism shows seven hands (sun, moon, five planets) and a double ring scale (outside: Egyptian calendar, inside: zodiac). This worked, but it loses all the detail in the varying modules between the teeth (from roughly 0.44 to 0.58). It is more probably that it was used to provide a mechanical model or to a didactic use. From $7.95 Adding Machine Patent Print. It is a business machine. Do you use a depthing tool to layout the arbors? I have prototyped the k1/k2, e5/e6 gear train and plan to prototype the inferior and superior planets next. These can be found in Freeth and Jones’ “The Cosmos in the Antikythera Mechanism.”. Naturally the Freeths articles in 2006, 2008, and 2014 have been extremely enlightening and exciting. There is a 3D printable design on the thingiverse: 3d 100% printed antikythera mechanism by Kirolab I don’t know of any other publicly shared STL files for the Antikythera mechanism. 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. I great appreciate your craftsmanship to design and cut the pieces via the traditional method. Send-to-Kindle or Email . is something new available for experiments ? Have you thought beyond the gearing as to what your final design will look like? Has anybody made any additional development of this model? It may be different to what you are able to do though as I’m using wooden gears obviously which are quite forgiving and accommodating in all sorts of different ways when it comes to fixing and fitting – plastic gears may need a bit more thought… I noticed that you had a separate fixed gear for venus and the solar anomaly. It was recovered in 1900-01 from the Antikythera wreck, but its complexity and significance were not understood until decades later. My design will follow the ISAW paper for the gear train, although I may consider using the 145:46 gear ratio for Mercury. Good questions! I want to make one and would like to see what others have done first. They work, but aren’t great. I can’t see the point of cutting all these gears if people can’t actually see them! I’ve put links to a coupe of photos of how I’m getting on if you want to have a peek. Favorite; I printed this design; Add to collection; ByKirolab3D. I’ve gotten it to a point where I’ll need a laser cutter to test out design options, so things are pending me finding one I can get. I worked pretty much from the gear counts alone. With the following exceptions! The mechanism is technically more complex than… 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 … By day, I’m an engineer in snowy Denver CO, and by night I cook, tinker, and enjoy the night downtown. In it tells that the original mechanism includes mechanical solutions to avoid errors of 2 degrees, but the triangle teeth gave errors of almost 15 degrees. Reverse Engineering the Antikythera Mechanism. Just curious, that’s all. Thingiverse is a universe of things. The model relations are perfect, the gearing is not. I am still thinking about how I want the front and back plate to look. - kirolab/3D-printed-Antikythera-mechanism My personal pleasure in this gadget is what it says about the mindset of its creators, and the direct association they had with the Earth and Cosmos, I reckon they are the precursors to Quantum Mechanical thinkers because everything they said and did was timed to, and for the reason, that the stars and planets acted out above them. The modern gears (evolvente) have already a small tolerance. If you need any more complex info use my email address – davidgoodchild69@gmail.com – easier than using the blog me thinks! I’m looking forward to watching your progress.

I made it in SketchUp using online photo references and specs. My machine is about 50% bigger than the original which is partly down to ease of building it, but also down to the fact that the original is really, really small, and I just wanted to do it bigger so that the person winding the handle has a fighting chance of actually seeing what was going on internally. For a CAD class this semester, I reconstructed the Antikythera Mechanism as a 3D model in Solidworks. Work fast with our official CLI. 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. After a flurry of enthusiasm from the new owner when the machine first arrives the handle will only be wound for 10 minutes a week, and probably not even that. This is a mouthful, but it basically means that you are free to use, edit, and redistribute these files so long as you a) credit me for originally making them, b) don’t use them to make money, and c) apply the same license whenever you redistribute it. The files “plate back lower dial v4.png” and “plate back upper dial v4.png” are taken from Freeth et al. A very loose printable sketch of the two thousand year old, shipwrecked analog computer. If you plop your email down at greekgears.com that will get you on the list of people I’ll notify when I finish up. 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. being the most ancient computer to be known so far. I’m starting to get excited now that the whole thing might actually work as planned! Plan C Live: Economic Recovery from the … Thingiverse is a universe of things. You folks are doing something interesting, and have probably convinced me a 3D plastic model will not be a working machine. do you have laser cutting files available for this? He is the author or editor of over a dozen books on technology, DIY, and geek culture. Whose Cosmos gearing did you choose, Freeth, Evans, or Wright? A more accurate model would account for variations in the gears. It is … This means they will be forever free. 3D Solidforms was found in 2013 and its main activity is the design and construction of objects with the use of modern technologies, such as 3D printing and 3D scanning. Runs smoothly and the motion is very apparent. It looks like you’ve made pretty incredible progress towards finishing it. It will be a skeletal design with engravings on the gear spokes and designs cut into the Date Plate, Superior Planet Plate, and bridges. The wooden frame, pointers, and posts are creative interpretations. Two indicators should slide onto the Metonic and Saros pointers, and track in the engraved spiral on the back face. I really should check back here more often and keep up – sorry. 5.844. Cool Crowdfunding: 3D Printing Shoes, Cake Icing, and Detecting Print Failures. Italicized issues keep it from working if it was 3D printed. That paper also says that k1 and k2 are offset by “just over a millimetre”, but I’m having difficulty finding a written number to distinguish between 1.0mm and 1.1mm. The Antikythera mechanism had the first known set of scientific dials or scales and was the most complex mechanism … Figure 2. All gears except for the lunar phase geartrain are assumed to have a module of 0.5. Unfortunately, there are a few issues that would keep it from working well if 3D printed right now. From $7.95 Camera Patent Print 1885. Can i use a router to carve the gears. (Like here: http://i.imgur.com/GpsK4f8.png). Complete Antikythera Mechanism Solidwork Files Total 50 MB There are two read me files inside with the comments of experiences of manufacturing , building. Solidworks had issues with a tangent relationship to a spiral, so these are suppressed in the model (but are still there!). Next job is to rip it all apart again and actually link it all together. The model uses involute profiles. This is actually the mean value of the modules for all gears in the Mechanism. I’ve got almost all of the centres for the main gear train cut now, and in isolation all the pairs run as near to perfectly as I can get. That’s fantastic progress! It could also be used to track the four-year cycle of the ancient Olympic Games. The large pointers should be removable in the real model to allow the indicators to reset. T he Antikythera Mechanism -The Designing and Building of a LEGO Version including designing and 3D printing the needed custom LEGO compatible gears.. In this new version I’m working on I’m basing it off that table in the Nature paper, after manually ensuring a module match between meshed gears. If nothing happens, download GitHub Desktop and try again. I don’t think it is any more a religious idea then than it would be now, it is the clockwork that matters, and how much money they could make out of the information it provided the users. Who knows, but it works for me and runs beautifully! Hi Dave, currently I am finishing my research, spreadsheets, and CAD drawings. I didn’t use values for the pin placement radii on the epicycle gears. 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). I love the way that the machine is still open to a fair bit of interpretation when it comes to the details. I hope that this helps at least a little, but our materials are very different so detail bits like this will tend to differ. I suspect mine will be oversized, at least 2:1 scale. Building a replica has been on my project list for a very long time and it finally made it to the top spot. You signed in with another tab or window. - kirolab/3D-printed-Antikythera-mechanism Check greekgears.com for future updates. Are you modeling to 1:1 scale, using the Supplementary Information section of the Nature 2006 paper, Note 3 (Gears) for the sizing info? It isn’t perfect. Cheers. Gareth Branwyn is a freelance writer and the former Editorial Director of Maker Media. My email address is davidgoodchild69@gmail.com if you want to drop me a line and then I can send you a photo or three if you want. In other words the one thing that really wasn’t an issue was wear and tear – I reckon that my machines will easily out last me (I’m 46). Unfortunately I know nothing of 3d printing, but having hand cut 60 or so gears Ican see the arattraction…. UPDATE! Thingiverse is a universe of things. Gareth Branwyn . If nothing happens, download the GitHub extension for Visual Studio and try again. Firstly, the Antikythera Mechanism was quite possibly based on the mathematical scope put forth by the earlier Babylonians, as opposed to the later-developed Greek trigonometry. From $7.95 Binoculars Patent Print. I too am going for the skeletal look. Watch the video to see it in action, and turn on annotations for a description. I can definitely let you know when I hit a milestone. By request, I’m making the CAD files for the model of the Antikythera Mechanism that I created freely available. In the artificial world there is neither mass, inertia, force, friction, nor elastic or inelastic deflection. See all stories. It will be all wood when finished and hopefully quite skeletal in overall design, I want to be able to see the gearing without horrible perspex!
