OpenAI just mentioned that while testing the “computer use” API they ordered many many shirts and now want to use the API again to issue the returns. The fact that they’re not embarrassed shows...

Ik kreeg laatst deze NU.nl link doorgestuurd en ben eens op onderzoek uitgegaan. Er werd gesteld dat door duurzame energieopwekking de CO₂-uitstoot binnen het ETS systeem met 15,5% gedaald is t.o.v. het jaar ervoor....

Arguably, our biggest power is the ability to choose how we interpret things. Given the recently unfolding events in the Israel-Palestine conflict, jumping to quick conclusions and rushing to judgement is as common as...

Sorry for for the click-bait title. There is not actually a secret, it’s been known for a long time that coal plants emit a lot of dirty substances besides the problem of greenhouse gases....

(I usually write in English here, forgive me if you need to use a machine translation!) We vinden het vanzelfsprekend dat het elektrische net goed werkt, echter gaat er enorm veel menselijke energie zitten...

This is a simplified simulation of the mechanical “Cartesian bot” of The RepRap. It allows you to play with things like play (a.k.a. backlash), tension of the belt that drives the axis, etc. You...

I’ve created a gcode processor in php. [Edit] This is now documented here: http://objects.reprap.org/wiki/3D-to-5D-Gcode.php[/edit] It allows you to rewrite 3D Gcode from tools like Skeinforge and use them with the 5D firmware. I’ve added...

After Siert spent 5 minutes in Rhino CAD software, we had a printable model. The picture shows the bracket being printed. Installed on the WiFi bike Being at Reboot 11 was amazing. The theme...

I’m excited to go to Reboot. Siert and I will be (re)presenting the RepRap project. We plan to take 2 fully functional RepRaps with us. They have already been churning out parts to make...

Click on the image to see a bigger version. The detail is really good. I decided to print a chess piece. I was amazed by the quality. I really love the new extruder we...

In the group at Protospace (FabLab Utrecht, the Netherlands) we designed and built a new extruder. Most of the design work was done by Robert, and a very good result was obtained with the...

I personally think that the RepRap is a tool of personal empowerment. It allows you to take matters into your own hands. Are you not completely satisfied with some object that you use? You...

The exact topic is still preliminary, but my masters research is going to be on user innovation in fabrication and its interrelation with the commercial players, their products and their customers. The creation of...

Dit is een introductie tot de RepRap. Technische kennis, bekendheid met Open Source of de RepRap wordt niet verondersteld. Omdat de geluidskwaliteit niet optimaal is heb ik ondertiteling toegevoegd. De slides zijn hieronder beschikbaar....

If you agree with me on this, please take less than 30 seconds to nominate RepRap for “Most Likely to Change the Way You Do Everything”:

The driving mechanism that pushes the thermoplasts or metals through the heater chamber (for making them liquid) is a very critical one. It needs to push the plastic with a strong and reliable grip....

Today, antifuchs designed a stylus to be 3D printed on a home fabricator such as the RepRap or Makerbot. It was posted as a Thing on thingiverse.com. The stylus (click picture for lager version)...

There’s a reason why this video spreads like pig flu… Highly contagious. Not just harmful things can spread exponentially, also the beautiful things in life! (P.s. the HD version is highly recommended if it...

I wanted the RepRap to make beeps to confirm whether everything is connected and working. But of course you can have it make music as well! I wrote a script to make G-Code movements...

Video: Festo Bionic Learning Network 2009 Zie dit YouTube filmpje. Behalve dat het een erg mooi promotiefilmpje is zit hier een duidelijke visie achter. Bij FESTO is het interessant om te zien hoe zij...

I passed my last exam I have to do for my masters degree! I ‘only’ need to finish an internship and write my thesis… and then I’ll be Master of Science, in addition to...

Debugging sucks… I’m (re)building my machine, and one thing I’m missing is transparency. We’re adding layers to keep complexity manageable, but inevitably some transparency is getting lost along the way. There are several interfaces...

Two weeks ago I made print circuit board for a more advanced stepper motor driver, using the IMT-901. This is a chip that can drive power to the motor and control motion in a...

Update: fixed again. Update 2: fried again. Remembering from the top of my head that I had some PCBs with the silkscreen reversed, with an incorrect measurement I concluded that it must have been...

I read the Guardian article about “building an open source world”, on which I have some comments about this. In the article this remark is made: “Open source hardware doesn’t have the same power...

On my HTC Touch Cruise phone, I’m using a Android Linux and WM6 dual-boot setup. Up to now, when using WM6 on my phone I used to sync my phone with OGGsync to sync...

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...

A must-read letter, addresed to you. It is a beautiful call for progress: http://www.nickbostrom.com/utopia.html

“David Deutsch is een van de pleitbezorgers van de zogenaamde Vele Werelden-interpretatie van de quantummechanica, een uitleg die stelt dat er meerdere universa tegelijkertijd bestaan, universa waarin bovendien nog verschillende kopieën van onszelf rondlopen....

Dear Readers, Welcome to my Blog. I’ll be writing about fun things I do, interesting things I learn about and anything else that may spring to my mind. If you share my interest in...
