Snowflake Hat

This winter has been the longest and darkest in Berlin since 1951, so last month I paid another visit to Fabienne Serrière (FBZ) who you might recall from my earlier video as a hardware hacker and machine knitter extraordinaire. This time I had something of my own I wanted to knit. Inspired by Fabienne and Becky Stern and everybody else involved in hacking these machines, who built upon the work of others and then put their own improvements into the commons, I decided to draw on the commons to create an open source hat.

One of the best places to explore our cultural commons is of course the Public Domain Review, where I found just the right images to fit both my hat and the Berlin weather. Check out the video above to see how the hat came together!

One of many images from Snowflakes: a Chapter from the Book of Nature (1863) on the Public Domain Review

These images are certainly beautiful, but that was 1863, we’ve moved on a bit since then. Now, thanks to the aid of modern technology, we can finally present these snowflakes as the artist would have envisioned them, in glorious 1-bit duocolor:

So they may have lost a little subtlety, but hey, they’re on a hat.


You can see (and download) many more of these great snowflake drawings from the Public Domain Review. And while you’re there, have a look around, their collection is a fascinating, expertly curated look into our cultural history. Check out images of the Krakatoa Sunsets from 1883 (good name for a surf band, that). Cheseldon’s osteographical images of lively skeletons, and read the back story of the Brothers Grimm. Public domain content belongs to all of us – so you can browse the collection for inspiration, and feel free to re-use and remix. Why not screenprint your favourite Kamekichi Tsunajima woodcut on a t-shirt?

my choice: WILD HOG!

Need some material for your surrealist erotica? Look no further than the toothy vaginas of Emanuel Swedeborg’s erotic dreams. Dive into the back catalogue of the Elvis of the early 1900s, Enrico Caruso and you just might find inspiration for something truly marvellous:

What I really love about browsing the public domain or other free cultural works (such as those under Creative Commons Attribution or Attribution-ShareAlike licenses) is that there is always the possibility to just grab something and experiment. You don’t have to ask, you don’t have to explain yourself, or decide whether you may end up using something commercially, you can just go ahead and play. You already have permission to use these works for whatever you like.

You also have permission to make, alter, improve or sell this hat, under the Creative Commons Attribution ShareAlike license.

Building the RepRap Prusa i3 3D printer


A couple of weeks ago I attended Open 3D Engineering‘s first ‘Build Your Own 3D Printer’ workshop at Fab Lab Berlin to find out a little more about the process of 3D printing in general and the RepRap project in particular. I didn’t have the money nor the need to actually make my own printer, but there are a handful of things I would like to 3D print, so I thought it would be a great opportunity to learn more. While the 11 participants were untangling cables and programming microcontrollers, I was sticking a camera in their faces and asking stupid questions, mostly along the lines of ‘what does this button do?’ or ‘is that meant to snap in two like that?’

Occasionally I did actually get some hands-on experience, wielding big dangerous tools like hex keys or tweezers, but mostly I was there to watch and learn. I am currently building a machine of my very own though. As I said, personally I don’t have much interest in owning my own 3D printer just yet, but something slightly more suited to my lifestyle is a programmable open hardware camera slider. There’s also only one axis to worry about…

So I’m starting to put it together and 3D printing the custom parts with Bram, I’ll keep you posted – hopefully there will be some nice fluid time-lapse / stop motion / motion-controlled video footage in the next few months.

just waiting on a few more parts…

 

In the meantime, here are a few thoughts, theories and questions on the RepRap project:

To me, and many others, what is truly fascinating about RepRap is not just the sci-fi nature of converting bits to atoms. It’s not even the decentralised open source collaboration of the project. It’s the process of evolution in action and the exponential growth which can only come from a self-replicating machine.

To understand the thoughts behind the project, read Adrian Bowyer’s ‘Wealth Without Money‘, a short manifesto of sorts originally published in 2004, which lead to Bowyer creating the first RepRap printer in 2008.

In addition to founding RepRap, Adrian Bowyer’s other great life achievement has been making it into the 2013 Open Source Swimsuit Calendar

 

Further reading on a different aspect of the RepRap project: developer Erik De Bruijn’s Master’s thesis “On the viability of the open source development model for the design of physical objects – Lessons learned from the RepRap project“[pdf]

You might wonder how anyone has time to develop 3D printers and earn a living at the same time – contributors aren’t paid to improve RepRap machines, and as the designs are open source, nobody can claim a commerical monopoly on their designs. So how do they make a buck? Is Adrian Bowyer flipping burgers part-time?

There’s no commercial company pulling the strings behind RepRap, although many of the people deeply invoved in the project have ended up using their expertise to start their own companies or otherwise work professionally around the project, providing an interesting look at the business models which arise without a commercial monopoly.

Adrian Bowyer’s company RepRap Pro, for example, makes and sells RepRap kits and provides training in 3D printing, benefiting from his experience and status within the RepRap community. Josef Prusa, designer and namesake of the Prusa i3 we were building, has written a book called  ‘Getting Started with RepRap‘ in addition to running workshops and offering 3D printing consulting. Erik De Bruijn’s commercial project, the Ultimaker 3D printer, is one of the most popular domestic 3D printers and was recently rated ‘Most Accurate’, ‘Fastest’, and ‘Best Open Hardware’ in Make Magazine’s in-depth test of 15 3D printers. There’s also a growing ecosystem of parts, electronics and filament supply specialists around the project.

One interesting point in de Bruijn’s paper is that the RepRap community is doubling in size every 6 months (or was, in 2010 – have any further surveys been made?). It made me wonder about the diversity of people getting involved. In his survey de Bruijn looked into demographics based on education, age and background, but one thing you may notice from the workshop video is that all participants were male. I’ve tried to find information on the level of participation by women in RepRap or 3D printing, but haven’t come across much. RepRap is basically at the intersection of two very male-dominated fields, mechanical engineering and free software, so perhaps it’s not surprising that (to an outsider, anyway) there isn’t much visibility of women in the project. Are there many high-profile women in this area? Has there been much discussion of the subject? Got any links to articles?
