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). Michael T. Wright, FSA (Born: 16 June, 1948) was formerly curator of mechanical engineering at the Science Museum and later at Imperial College in London, England. 3D Printer Patent Print. Update June 2015: I’m revisiting this project to finally get it to a version where it can be manufactured at home. 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. Can’t wait to build the model. Wondering why you used a scale factor for calculating axle distances. He is the author or editor of over a dozen books on technology, DIY, and geek culture. Designed and build around 205 to 60 BC, It was found in 1901. Learn more. Solidworks had issues with a tangent relationship to a spiral, so these are suppressed in the model (but are still there!). T he Antikythera Mechanism -The Designing and Building of a LEGO Version including designing and 3D printing the needed custom LEGO compatible gears.. - kirolab/3D-printed-Antikythera-mechanism 100% 3D printed interpretation of the Antikythera Mechanism. Gareth Branwyn . This has changed the homogeneity of the original metal (if there was any in the first place) making it incredibly difficult to extract the mechanism from the CT scan to produce a 3D model. did you update google drive model ? is something new available for experiments ? - kirolab/3D-printed-Antikythera-mechanism [IMG]http://i1295.photobucket.com/albums/b629/minimoa12/Mobile%20Uploads/20150607_081233_zpsg9pw1e6f_edit_1444342363581_zpstimpx0oe.jpg[/IMG], [IMG]http://i1295.photobucket.com/albums/b629/minimoa12/Mobile%20Uploads/20150607_081328_zpsegrmoa39.jpg[/IMG]. Sorry for the late response – been a bit tied up the last few days. Many theories there are to explain it. Categories: Physics\\Mechanics. My design will follow the ISAW paper for the gear train, although I may consider using the 145:46 gear ratio for Mercury. Check greekgears.com for future updates. It’s a wonder the Antikythera mechanism was discovered at all. Still have work to go, but I’ve gotten as far as making some test parts on a laser cutter. I haven’t figured out how best to do that yet. The front of the Antikythera Mechanism shows seven hands (sun, moon, five planets) and a double ring scale (outside: Egyptian calendar, inside: zodiac). I sized a couple of the larger gears according to dimensions from the device's Wikipedia entry, and put the right number of teeth on them too. It doesn't tell time or anything, but it looks cool. I wonder if you can help me a little. 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. For a CAD class this semester, I reconstructed the Antikythera Mechanism as a 3D model in Solidworks. Calculating axle distances = Ad=0,5M(Z1+Z2). Unfortunately, there are a few issues that would keep it from working well if 3D printed right now. A very loose printable sketch of the two thousand year old, shipwrecked analog computer. Great Scott! Hi Dave, currently I am finishing my research, spreadsheets, and CAD drawings. Thingiverse is a universe of things. I’ve done quite a bit of work on a new version that will actually be manufacturable rather than just being a computer model. Have you thought beyond the gearing as to what your final design will look like? For those who doesn't know The Antikythera Mechanism is an artifact found in 1900 in the coast of the greek Antikythera island, once studied it was dated to be from 200 B.C. The model relations are perfect, the gearing is not. 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). 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. Just thought you’d like to hear that I’ve sort of got it running! "Resumen en castellano al final" For those who doesn't know The Antikythera Mechanism is an artifact found in 1900 in the coast of the greek Antikythera island, once studied it was dated to be from 200 B.C. I enrolled in the BHI’s distance learning program (but did not take the tests). They work, but aren’t great. 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. I’ve been looking at this model in SolidWorks and MasterCAM and am hoping to build it. It was constructed between 150-200 BCE and was used to calculate the exact position of There is lots of us out there that don’t use solidworks that could support the development in our own software preference. The wooden frame, pointers, and posts are creative interpretations. You folks are doing something interesting, and have probably convinced me a 3D plastic model will not be a working machine. 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). It is a business machine. The moon gearing (k1 and 2 especially) is probably the trickiest bit to set up, and don’t forget that although they all have 50 teeth, k1 and E5 are slightly smaller than K2 and E6 – but I’m guessing that you’ve already spotted that! Can you please direct me? By day, I’m an engineer in snowy Denver CO, and by night I cook, tinker, and enjoy the night downtown. 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 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).
