Discussing energy, open source innovation, 3D printing and philosophical themes
I’ve settled for a WM6 equipped HTC device: The HTC Touch Cruise. A fairly nice device. It doesn’t look as fancy as the iPhone, but it is very well equipped and there are many...
Monday evening, I’ve been to a reading on peer production in Amsterdam (@ Waag Society). Besides the excellent talk, I met some wonderful people as well! I had heard and read about the peer...
You may have noticed ‘Use Firefox!’ pictures on many websites. There’s a story behind this which applies to me as well. As a web developer, even when you only use Linux, you inevitably get...
When researching the distributed user-centered innovation process, I came across this lecture by Eric von Hippel (see below). Also, in my presentations I’ve quoted Eric von Hippel a couple of times. He researches how...
There is considerable talk about a revolution that awaits us in personal fabrication. A lot of the news reaches me, but mostly not the mainstream media, YET. Fabrication tools (Fabbers) such as the RepRap...
These are some tools that saved me a lot of time and frustration building my RepRap. I should have bought some of these tools sooner though! Click image to enlarge. On the left is...
A couple of weeks ago, the day before I was about to give a talk at the Wikimedia conference, I had a small set-back. After changing from electronics platform earlier on, my RepRap machine...
Nederlandse versie: zie onderaan At FabLab Utrecht, a.k.a. Protospace several RepRaps are going to be built (five to start with). I’m supporting the group with advise (and of course encouragement 🙂 ). It will...
If you haven’t seen Zeitgeist the Movie, go see it now (ps. you can turn of the Dutch subtitles by clicking on the CC button). It’s free to watch online and you may copy...
The pictures of the green city lab are available at fablab.waag.org. All in all, it was a really fun and interesting event where I met may wonderful people!
What does the RepRap project do? What do they mean with self-replication? Its aim is to design, through the open source process, a 3D printer that can replicate most of its own parts. Currently...
I’ll be speaking on the RepRap at the Wikimedia conference in Utrecht on 1st of November. The programme is in Dutch. See also the www.wikimediaconferentie.nl website
The gears in my acrylic extruder were skipping where there was a moderate amount of resistance given by the drive shaft. Also, because of the distance between the two gears being too big, there...
[update] Inmiddels heeft een filantroop zich aangemeld en is er nu $100.000 prijzengeld beschikbaar voor een (sterk) verbeterde RepRap (volledig in lijn met mijn voorstel)! Meer info… [/update] Dit is een open oproep voor...
This is version 0.1 of my reprap controller. I don’t have much time to work on in so I’ll publish it in a non-finished state (then again, what is ‘finished’?). It still needs an...
Something I almost forgot to share is the optical encoder disks. I made those when Chris made his achievement on the encoder. The encoder on the extruder is an important step towards better 3D...
I just visited a conference about the launch of GPLv3. There was a very nice ambience. People I talked with were very interested in the possibility of the RepRap, and about it being a...
In anticipation of new thermoplast extruder parts, I built a Dremel toolhead for my RepRap. It should be able to do light milling, such as PCB isolation routing! I was hoping to do some...
We’ve adopted this cute little cat. We call him PIXEL. We liked the name, perhaps because pixels are small they can be fun to look at? When he grows bigger we could always change...
It’s always nice to hypothesize about the future. I think most will agree that nano-technology (as in nanomanufacturing) just isn’t there yet, not discounting ‘smart fabrics’ (nanomaterials) or chemistry for that matter. As you...
Isn’t it great that you can script anything in an open source OS such as Linux/Ubuntu? Dcop rules. A good reason not to use windows (for me that is). If you still bound to...
Printcrime (Originally published in Nature Magazine, January 2006) The coppers smashed my father’s printer when I was eight. I remember the hot, cling-film-in-a-microwave smell of it, and Da’s look of ferocious concentration as he...
"If I can build a RepRap Darwin, I can build almost any machine." — Me Because of the experience I got from it, and because of the fabrication possibilities it creates. This was one...
I like my own time lapse video’s of the RepRap 3D printer build but that’s documentation. This guy makes a real art of it (well, actually he reversed some video’s, ahh well) and uses...
That’s too bad. I thought I was almost done. With the 100nF capacitor it worked better. Now I still have the problem that it more or less stops heating in cycles when the power...
I like new computer interfaces. It’s amazing that the Wii is allowing many people to make their own creative hacks that are actually quite powerful. Wii finger tracking 3D tracking I can imagine that...
More progress, more videos! I had a lot of time on my hands this week, so I almost finished my RepRap! Here are some time lapse videos. Gaining height: part 1 (40 minutes of...
After receiving all those bits (from bytes) I had to postpone my build further because of an exam. That’s done now. I can finally start RepRapping!!! To document my build, it would be nice...
The bits finally arived! Too bad I have an exam tomorrow. This kind of suspense is probably lethal. Anyway, here are some pictures and a small review. I’m really satisfied with the quality of...
A while ago, while I was waiting for the BitsFromBytes stuff, I had to do something. So I decided to tidy the things I already had made. This is the result of the PIC...
This is from a survey among industry leaders in Rapid Manufactoring: "Krailling near Munich, January 28th, 2008: Mass production in the Western world is on the brink of a silent revolution and e-Manufacturing is...
Project RepRap I’ve started building a RepRap. Read more… Also take a look at the website: www.reprap.org What is the RepRap In short: It is a 3D printer capable of printing it’s own parts....
Finally, I’ve finished the bachelors’ thesis! The subject was "BIOLOGICALLY INSPIRED COMPUTING: The emergence of intelligence through evolving Artificial Neural Networks" and it was awarded an 8 out of 10. Well deserved if I...
Watch this video, and notice the funny T-Shirt at 9.39s. If you don’t get it, and you don’t hate philosophical topics (I mean why this cat is alive…) just google for Schrödinger’s Cat.
Personeel van Walibi Belgie gooide onze tas van een trap af. Nu blijkt dat mijn mooie digitale camera stuk is, en ze willen hier niet eens een deel van vergoeden! Summary in English: I...

For those who have seen the 3D technology from the movie "DéjàVu"… it’s real. Researchers have found a way to combine satellite images, 3D models of structures (such as buildings) and live (web-cam)...
The subject matters. That said, the form as well… I only wished our professors would do their lecture like this: http://video.google.com/videoplay?docid=4237353244338529080#10s It seems however, that the Swedish are able to repeat the trick: http://video.google.com/videoplay?docid=7996617766640098677#10s

The upgrade from Ubuntu Dapper to Edgy Eft. Note: at this time the beta 1 is just released, but I got too curious.
