Making Living Sharing – Trailer #1

No matching videos

It’s finally online, the very first trailer for my upcoming research documentary. The movie will be about my adventures in global collaboration and local fabrication. How can we help people create their own products? How can we make a living from sharing?

It will feature shots from FabLabs and projects around the world, animations about design by sharing and interviews with various makers and generally awesome people.

Making Sharing Living will premiere in August 2013 at FAB9 in Yokohama, Japan

Master mould for prototyping prosthetic feet

master mould - finished-scaled

I designed and CNC milled a two piece mould foot that can be used to create negative soft rubber moulds. These moulds can be used for experimenting with different casting solutions and techniques. The positive master mould can also be used for shell forming techniques with a leather and other materials. Continue Reading →

Casting the rubber component of a prosthetic foot sketch

The finished prosthetic foot sketch, the principle looks promising

We used a two component rubber resin of polyurethane type for this prototype. The wedge shaped rubber will provide exponential resistance as the prosthetic foot bends forward. The rubber also packs around the metal hinge pin to reduce shear stress. Continue Reading →

CNC milling the parts for a prosthetic foot sketch

The finished two sided milling job

To get some feedback on the potential of the rubber wedge foot, we CNC milled a sketch at HONFablab Indonesia. We used massive wood of the Keruing type and a flip part setup to create the parts. Continue Reading →

Winning the FAB8 flight competition


Knut Klo, Haakon Karlsen Jr. and I won the FAB8 design competition in Wellington, New Zealand. Our hexacopter easily managed to stay the required 30 seconds in the air. The amazing guys at Phothigher saved the day by lending us one of their micro controllers when we couldn’t get the Ardupilot to work in time. Also a big thanks to all the people from the FabLab community who helped me troubleshoot the RF communications. More pictures in the post. Continue Reading →

First takeoff with the hexacopter


No matching videos

We had a very very successful first test flight with our hexacopter. Extremely cool feeling to CNC mill your own propellers and then see them take off into the sky. Press the “Download this design button” to get our drawings for laser cutting and cnc milling. We would love all kinds of help on developing the flight electronics with the FabLab PCB milling process. A more detailed tutorial on building your own is coming soon.

the Layer Chair – Sevilla edition

No matching videos

I showed the ongoing Layer Chair project here in Sevilla and it turned into a very interesting open design collaboration. Three groups of students at FabLab Sevilla downloaded and customized their own versions of the Layer Chair. One group was inspired by the classic Eames lounge chair, one group made the perfect chair for architecture students and the final group experimented with weaving a seat from thin rope.

The chairs are currently exposed and for sale at gallery Lugadero in Sevilla. For the opening night I created an interactive chair design system where visitors could design a chair with their own body. With the Kinect component for Firefly I could read out the position of the visitors head and hips. The height of you head determined the height of your chair, and the angle of your back determined the backrest. Tracking two people at the time making their own designs was very entertaining.

It was an interesting experience to exhibit a design system and an open process instead of showing a finished product. More open collaboration communication coming soon. Continue Reading →

The Layer Chair – Viking edition

lyngen chair01

At MIT FabLab Lyngen, Haakon has a very interesting table and chair project going on. He is going to replace the main dining table with a large fjord-like table made from massive wood. And the chairs will be replaced with 16 tall ones, with profiles matching the 16 highest mountain peaks of the Lyngen Alps. After telling Haakon about my parametric chair project, there was no doubt that we had to combine our ideas. Continue Reading →

Prosthetic foot, articulated prototype sketch

No matching videos

A test of an articulated foot system for the Lowcost Prosthetic program of FabLab Amsterdam and HONFablab. Based upon the articulated foot research of Nancy Seto, intern at FabLab Amsterdam.

This design sketch aims to use the inner tube of a bicycle tire for providing the elastic tension of the foot. This material is cheap and widespread around the world, making it possible for the user to replace parts without tools or specific knowledge.

Next step will be experimenting with casting rubber as a flexible ankle joint.
