Self-replicating 3D printer: von Neumann machines on Mars?
Self-replicating 3D printer: von Neumann machines on Mars?
If you're new here, you may want to first register and subscribe to the RSS feed. Thanks for visiting!Is this self-replicating 3D printer a von Neumann machine that will someday go to Mars? Yesterday, we experimented with our idea of Instagram to 3D printed jewelry for the more popular monochrome photos in our feed. The technology worked at some level (we have jewelry on Shapeways now, based on a previous IG photo post). But it took too long and too many artistic decisions to get it there. It wasn’t quite blinking lights automatic the way our earlier virtual fashion shoot could be. So this is a good time to step back and explain what 3D printing is or can become, for those we are less familiar with it. This is Mandel, a version of RepRap. RepRap is an open source hardware project to build a fully self-replicating 3D printer. That’s right, a 3D printer that can print a copy of itself.… Read the restMaker movement: from blog post to silver jewelry
Now that we have a virtual clothing line (courtesy of yesterday’s virtual fashion shoot post and on-demand maker movement), we figured we need a virtual jewelry line as well. We’re data scientists, so we deal with a lot of infographics. Why not convert our most popular infographics into on-demand silver bling courtesy of the maker movement? As before, this is inspired by our IG-feed as well. Although there are pre-existing apps and maker movement techniques to convert color and greyscale images into 3D printings, the materials and techniques are more limited. The best candidates are monochrome images. We have quite a few. Many of these are, in fact, real world objects: wood-cuts or other engravings or embossings that were designed to be physically manufactured as some point. Unfortunately, 3D printing and the maker movement are in their early stages. In general, for most materials, 3D printing and the maker movement can’t handle detailed engravings yet, especially if we want to make only a small pendant.… Read the restVirtual Fashion Shoot: Acculation Fashion Line (VR data #glamour)
This time, our data-driven decisions have led us to glamour, our own clothing line, and this VR virtual fashion shoot. Who says big data analytics have to be boring? First, some background on what got us here. Remember that, umm, ‘marketeer’ who suggested (in a comment on our IG feed) that we drop data science (one of the hottest fields at the moment) and instead sell his clothing? The comment was likely automated, but we had fun with it anyway. We told him we were too busy working on our perfume line. (“Data science: the new fragrance for men.”) But then we realized — technology exists to turn our IG feed (and the photo posts on this blog) into a fashion collection. So we wanted to do a fashion shoot. But models can be hard to work with. (They got agents, and, uggg, what a hassle. We live in LA, so we know.)… Read the restmath pattern art: mathematical quilting & design
Mathematical quilting and math pattern art & design: shown here are 17th century Italian quilts made from mathematical patterns. Yesterday’s Hamming metric (or Hamming Error Correcting Code) quilt got us thinking. Turns out there is a branch of quilting making (or perhaps a branch of mathematics if you will), “mathematical quilting.” It looks to math — polynominals, Rule 90 cellular automatons, etc., for inspiration in quilt making and pattern art. Shown here is so called “Florentine work” because these popular quilt designs are based on mathematical patterns originally found on chairs in the Bargello Palace (today an art museum) in Florence Italy. These chairs date to at least the 17th century, if not earlier. There are many types of these quilts, which are typically very colorful. The quilting requires precise counting of squares so that the pattern art design conforms to the mathematical pattern chosen. So yesterday’s crazy quilt, in which math creates art, isn’t unique.… Read the restHamming distance: Crazy Quilt Error-correcting Codes
Shown here are Hamming distance error-correcting codes in an illustration resembling a crazy quilt. In yesterdays’ post we pondered that aliens looking at the Sagan-designed Pioneer Plaque might have a hard time finding Earth due to the various data error. (These were due to the limits of science back in the 1970s.) Some people might regard the errors as a good thing. (Maybe we don’t want aliens to find us. 🙂 But there is some redundancy in the Quasar timing uses. (In part, there had to be, because the timings will slowly change.) Sending a message with extra, redundant information to help the receiver correct errors is known in coding theory as a Forward Error Code. Space aliens trying to decipher the plaque might have to use something more advanced — probably based on Bayesian statistics, the sort of statistics error-detecting and correcting algorithms we’re starting to see in advanced artificial intelligence algorithms that use statistical inference.… Read the restRecent Comments
