how to make antikythera mechanism

Among other finds was the Antikythera mechanism, which is the ancient mechanism of the highest level of sophistication among the mechanisms that have been found until now and is considered as the highest technology mechanism in antiquity. I'm not sure what that is yet... Like TobyMac said, the blue number is there to indicate the exact length of the axle in LDU's (. Personally though,  I would just redesign the hand with easier to find technic parts and use axles instead of the bar and antenna. Well, I finally got mine built and calibrated and verified. so amazing and complex! The Antikythera mechanism is according to researchers another product of Greece. On my recent vacations to Athens I visited National Archeological Museum where the Antikythera is displayed. I'm really surprised at how trouble-free the mechanism has been under more-or-less daily use; early on I had to add bushings to keep two gears from slipping. Andrew Carol's Antikythera Device Lego model. Memory for registers and program is given as a black box--by this point you know enough to design that, but it would just add a lot of components and complexity, and slow down the simulation, and the time spent dealing with it would distract from learning the topic of this part of the course. If it's an interesting Wikipedia submission, those are on topic. It was discovered in the Antikythera … No need to posit a conspiracy here. You are very welcome. I've also added some text to help explain what each component is doing. The kids may not understand the saros, but they love watching the gears turn. So if you are wanting to see those bronze fragments in real-time, you have to make a trip to Athens, Greece. I'm on the west coast north of Andrew Carol's location so his Saros Dial should work for me, but aside from surfing recent eclipses and trying to guess and match the patter on the Saros dial... even an exact date for a couple of the eclipses (saros spiral level 1-4 and position) would help along with where the hour adjust should be. There is no other instrument like it, nothing found until today compares to the Antikythera mechanism and better yet, there are no recorded texts that would suggest that something like it ever existed. In 1900, a group of Greek sponge divers were sailing back to Symi, an island in the Rhodes region of Southern Greece. I haven't actually looked at my build for ages now. If you want to make civilization resistant to collapse and increase its ability to recover quickly: bury gear cutters, lathes, magnifying glasses, precision tools, etc. It is sophisticated, complex, and ingenious to the point for years science could not explain its purpose, and only in 2005-2006 it was possible to finally understand at least part of its complex nature. In the year 1901, artifacts are retrieved from sea. Got it, thanks a lot! Antikythera Mechanism and its known fragments are currently placed in the National Archeological Museum in Athens. Hello Edgerton, . I like to research fine weapons. It’s a wonder the Antikythera mechanism was discovered at all. I tried to access your site from the information you supplied, trying many arrangements, but to no avail. A dial on the front combines zodiacal and solar calendars, while dials on the back capture celestial cycles. What is remarkable is how much is crammed into such a small space. The first teaches "[...] digital encoding of information, principles of digital signaling; combinational and sequential logic, implementation in CMOS, useful canonical forms, synthesis; latency, throughput and pipelining". The Antikythera mechanism is one of the world's oldest known geared devices. I believe that the bulk of knowledge, in most fields, is passed from person to person through active practice, not through books. I am so very pleased that someone was able to do the reverse engineering for this device. The Antikythera Mechanism tracked planetary positions, predicted lunar and solar eclipses, and even signaled the next Olympic Games. It is not quite the mystery that the pyramids are, but it definitely will leave the average person scratching their head. It's not as hard as you probably think it is. This website brings to together all relevant information, like publications and videos, about the ancient Antikythera mechanism. Transistors give you logic gates and opamps, from which you can build computation and memory, add a clock to apply input from a certain address (the PC) to a set of logic gates (the instruction set) that can read and store and you have a very crude (and very inefficient) programmable CPU in no time (compared to something even remotely like a 8080 or even a 6502). If you really wanted to make society collapse resistant, including a manual about how to do so, a couple of tungsten carbide bits, and a couple of hacksaw blades with every car would probably do the trick. 234 likes. So I've made extensive modifications to the instructions with lots of arrows to help show what goes where. The Antikythera mechanism had the first known set of scientific dials or scales and was the most complex mechanism … I highly recomend seeing this device and its recreations live there. But what is the blue number in the small black box in the upper right hand corner for? You are correct. The second covers "[...] instruction set architectures and assembly language, stacks and procedures, 32-bit computer architecture, the memory hierarchy, and caches". I doubt Intel writes down everything they've figured out. For anyone interested, the Clickspring YouTube channel is recreating the Antikythera Mechanism. I had a friend in honours year computer science who did a project on tomography of the antikythera mechanism (working on image analysis software to remove ghost images of other layers), and helped discover why his advisor's previous model of the mechanism was mechanically immobile (when you turned it, it locked). I perhaps should have been clearer what I think I was asking. Their ship was in a channel north of Crete, near the small island of Antikythera. Antikythera mechanism, ancient Greek mechanical device made of bronze and used to calculate and display information about astronomical phenomena. The instructions are (visually) correct though. The Antikythera Mechanism can not possibly be real or have ever worked because the original fragment does not have enough gear wheels to make it run. Hello Edgerton, my school is planning to make a Lego Antikythera mechanism. Fascinating! Thank you Andrew and Sean (WillPilgrim) for all that you have done. This a page charting the ups and downs of building working replicas of the Antikythera Mechanism. In short, Antikythera mechanism is the most ancient mechanical analog computer know to human kind so far. On a related note: what is humanity's Bus Factor for creating a CPU? https://www.youtube.com/watch?v=ML4tw_UzqZE&list=PLZioPDnFPN... https://en.wikipedia.org/wiki/Antikythera_mechanism#Similar_... https://www.edx.org/course/computation-structures-part-1-dig... https://www.edx.org/course/computation-structures-2-computer... https://www.edx.org/course/computation-structures-3-computer... https://www.bbc.co.uk/programmes/b0bk1c4d. Hope you managed to get the build done in the end. The Antikythera mechanism is defined as an ancient Greek analogue computer which is mainly is to determine the astronomical positions, purpose of astrological, eclipse for calendar. In short, the dial works for any location on Earth. Thanks so much for getting back to me. Yep. It was essentially an extraordinarily expensive toy. This seems to happen a lot. Got it ! I think everything else you need (welding equipment, drills, etc) would be fairly straightforward to cobble together. Dude you are the best!! The oldest extant complex geared device was recovered from a first-century B.C. He has UT Saros dials which are probably much better. I, too, wish LEGO would make the kit! Our mechanism has been enjoyed by thousands of visitors to our museum over the last three years. Why wouldn't they be? Not only is he recreating the mechanism, he's also exploring antique methods and materials that were possibly used. The Antikythera Mechanism and now you can make one also. Could you please share the Saros dial with us? Turns out there is not a part that connects the bar to the hinge cylinder - the original stock photo of the 1 x 12 bar I had did not show the extension of the bar past the one stud - so all is good. Below is a recreation of the Antikythera mechanism. The device seemed to have a range of interlocking gears made of bronze and a hand crank to give a turning movement to the geared mechanism, plus a display that showed information about the moon, sun and planets against a … The University of Houston's College of Engineering presents this series about the machines that make our civilization run, … The Antikythera mechanism is an ancient Greek analogue computer used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance. Wow! In fact, eliminating the (US west coast) geographical bias inherent in the original Saros dial was my entire reason for reformulating it. And although it took them many years to rescue the Antikythera Mechanism from the realm of UFOs, they succeeded in the end. There are three main ways that people have attempted to make an Antikythera Mechanism. Apparently the process Colt used on their pistols to color and shine them is completely undocumented and now unknown. One of the things most interesting to me about the mechanism is that it devotes a lot of gears and hardware to making small corrections which get completely overwhelmed by the inaccuracy of the manufacturing. Specifically, I was thinking that the Saros dial may only show events visible from US west coast and that I'd therefore need one with additional or alternative events that are visible from Australia east coast. I have 3D printed a working model of the Antikythera Mechanism. Thanks for the prompt reply. I worked pretty much from the gear counts alone. It has puzzled and intrigued historians of science and technology since its discovery. I have uploaded the dial pdf's to my GitHub: . to find out if you can build this MOC! A most remarkable and awesome achievement! Glad you enjoyed it. Got 120 hours and want to become one of them? The Antikythera Mechanism, named for the area in Greece where it was discovered, is a mystery in the sense of the genius it required to design such a functional and accurate mechanism. I saw this thread and wondered what happened to that project. Been awhile since anyone's posted on this build. The reformulated Saros dial uses Universal Time (UT) and is good for anywhere if you know the conversion from UT. For people that want to try this with a good quality 3d printer: Jonathan Blow draws some interesting implications of discoveries like this one in a recent talk: There is a really cool LEGO version someone built and you can see on YouTube. Here is what I had to do to calibrate it. Greatly appreciated. Rebuilding an Intel class modern CPU or just making a crude one? Please send me a message to dan at edgerton dot org and I'd be happy to send the files your way. The Antikythera Mechanism. Antikythera Mechanism Build. https://www.anythingaboutcars.com/early-1900s-cars.html, https://www.thingiverse.com/thing:1821540. Also, supposedly, the styrofoam used inside thermonuclear weapons. Now, if an eclipse -- solar or umbral lunar -- is visible from somewhere, anywhere on Earth, it's on the dial. I am good to go then. Hi dan, I have built the Antikythera machine and now want to calibrate it for Australian east coast (or globally). People died, and there weren't enough new people entering the field to learn it all before the critical mass of knowledge died with them. The most difficult part will be bootstrapping the ability to build accurate tools with which to rebuild an industrial society. The kids may not understand the saros, but they love watching the gears turn. It is only preserved if there has been is a continuous line of people preserving it. I've taken these, and can say they do a good job of teaching what they say they teach. :-). The Antikythera Mechanism’s Mechanics. We first give an account of the discovery of the Antikythera treasure, which was found by Symian sponge divers in November 1900. It was probably also used for mapping and navigation. I am OK with the UT concept and how to apply it. Or if it is, it's almost an afterthought, not the primary method of knowledge transfer. A good approach to get more knowledgeable is going bottom-up from transistors and top-down from FPGA (and suffer Verilog/VHDL), attempting to experiment and design your own instruction set while trying to understand the physics and logic, progressively bridging the gap in between in both directions. The Building Instructions for this MOC can be found on an external site: Create an account and enter your LEGO collection Great for Batman, not so good for us mere mortals. It's actually possible to build a working machine lathe out of the parts of an ordinary car engine. Once the storm passed, they decided to scout the area for sponges be… Expertise in both pin-and-slot techniques and epicyclic gearing simulating variable planetary motions was … https://hn.algolia.com/?query=Antikythera%20comments%3E0&sor... https://www.youtube.com/watch?v=pW-SOdj4Kkk. Sorry you must be logged in before you can do that. Does that make sense? Information from antiquity is lost by default. What book did you read to learn to tie your shoes, or drive a standard transmission? Even in more recent history, too. Sean, I can't thank you enough for all the work you've put into this. The complexity of the Antikythera Mechanism suggests that the device was crafted as part of an engineering tradition developed over decades or centuries. In the homework and labs you design and implement (in a simulator) at the gate level a 32-bit RISC CPU, except for memory. I'm a science teacher and I think this will be a very important build for my students to see... © 2020 Rebrickable Pty Ltd. LEGO® is a trademark of the LEGO Group of companies. It could also be used to track the four-year cycle of the ancient Olympic Games. Look like part 30552: Hinge Cylinder 1 x 2 Locking with 1 Finger and Axle Hole on Ends. I've got the entire right side of the machine calibrated, and it is extremely accurate, and is easy to do, but the left side, I'm at a loss. I'm really surprised at how trouble-free the mechanism has been under more-or-less daily use; early on I had to add bushings to keep two gears from slipping. So fascinating that I simply cannot avoid building it sometime in the next year or so. If you’re talking about losing the ability to recreate any particular relevant CPU, then. Just sent you an e-mail request. This guy on youtube is crowdsourcing a series where he is recreating the mechanism, I like the fact that these devices were well attested in history (. If you have a suitable Saros dial I would be grateful if you could share it. Unfortunately the recycling of valuable metal, both in ancient and medieval times, has resulted in nearly all mechanisms being destroyed. Could you please share the Saros dial with me ?. Ohh exciting. Astronomer here. Click here for audio of Episode 1031. 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. The museum displays them from time to time with various artifacts from the Antikythera wreck. The gear to use for the calendar dial needle is 6542a (not 6542b).
