Stadsherberg 2024

At the stadsherberg (city inn) just before Xmas 2024 I gave a workshop light boxes. Construct your own light box. Cardboard, lights, pencils, acrylic markers and of course glitter were provided. I only had to prepare it, for the participants it was obvious what to do: have fun together, share the stuff and i could “sit on my hands” (watch and enjoy), occasionally gently creating a working place for other participants.

Piz Roseg model

3D printed model of the mountain on the border of Switzerland and Italy. Usually a cad program that uses heightfields (greyscale to elevation) is limited to 256 steps. That would result in stepped slopes, not nice to look at. I used Rhino 3D and grasshopper to import the original geotiff files with a higher resolution (16 bit = 65K levels). Much better, smooth slopes.

Janninks light

Janninks tower, part of an old industrial building in Enschede. A couple of years ago i made a lantern from it with the little candle LED’s. And now it is also working with 220V lamps. It took a while to rebuild it, the thin paper design has evolved into two lamps: a thick cardboard design with a pucklight on batteries and a 160 gr paper design with 220V lamps. I’m particularly happy with the shade inside that guides the light very well.

Safety is always a concern with 220V applications. I use LED lamps (E14 fitting) that do not turn hot. But you never know. So I experimented with flame proving the paper and found a good solution that makes the paper flame retardant, this works well. For the children I also made a variation that uses a battery lamp. Much effort was spent to make it easy to build. It is safe and the lamp can be constructed without folding or gluing.

Welding a trailer tipper

I’m building a frame to turn the trailer on it’s site and move it through a narrow corridor. It is for an exhibition in the Vrijhof at the Twente University.

it’s constructed with the original edge posts of the trailer and it will slide in position. A “key” will lock it in place. It is a crazy idea, flipping the trailer. Why don’t people just walk out to have a look at it.

Here is the site of Lumi.
