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 →

Wedge based prosthetic foot sketch


This is an illustration of the a design principle for the 50dollar prosthetic leg program. The basic principle is to use a a rubber wedge that will create exponential resistance as the foot fends. The amount of resistance can be varied by casting different stiffness of rubber or by creating open “pockets” within the cast rubber. The design is largely based upon design input from Haakon Karlsen at MIT FabLab Lyngen. 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.

Hexacopter in development

discussing hexacopter

We have started work on a six rotor multicopter here at FabLab Lyngen. I am planning to use the hexacopter to make aerial shots of FabLabs around the world. Knut Klo is will be creating 360 degree panoramas from the air. Our collaboration got kicked off by Knut buying the Dji Flamewheel kit and showing his first panorama shots to Haakon. Haakon quickly realized that we could make a better frame and propellers in the Lab, and now the three of us are collaborating on a FabLab hexacopter. Continue Reading →

the Layer Chair – Band edition

Band chair detail

The latest CNC milling experiment is constructing by plastic bands instead of glue or screws. The layers are kept together by tight plastic bands and clips, the type you normally use for sealing cardboard boxes and pallets. The challenge was to keep the layers aligned without dowels or pins. I updated the parametric system to make wider and narrower gaps according to the surface curvature at each layer. The closer to the edge, the wider the hole needs to be for the band to fit through.

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.

The Layer Table

Layer Table - by DyvikDesign - 01

Now that Alex had some fancy new black chairs in his lab, he realized that he wanted a table to go with the chairs. So, I designed a parametric table that matches the shape language of the Layer Chair. The design lets you specify the measurement of any plate you would like to use as a table top. The output of the Grasshopper definition is a table frame that fits your plate of leftover material.

The Layer Chair – Amsterdam edition

Layer Chair - by DyvikDesign - Collection of three

Alex Schaub (FabLab manager Amsterdam) liked the Layer Chair I made in the HONFablab Indonesia so much that we decided to make a few for his lab as well. We used one sheet of 18mm black MDF per chair. Colored MDF is a very intersting material for making large objects on the ShopBot. We are currently investigating different finishing processes like lacquering and waxing so that the chair will be spill proof.
