Double Pendulum

Double Penedulum

Grethe Mo was producing a solo theatre performance about (fear of) math. She wanted some kind of visual effect to visualize the beauty of math and numbers. Quick brainstorming with Anne-Sophie Eriksen and Kjersti Høgli led to this:

A table mounted double pendulum. Ironically enough a demonstration of chaos; where the math and numbers break down.

The devise is made by home milled aluminium leftovers from the Grenland Friteater storage. All joints have ball bearings to give a long lasting pendulum. The finish of the bare aluminium parts are gently sanded to give a matte look and to remove scratches from the old materials.

Immersive Space Invaders

Intel has a Perceptual Computing Challenge going for their kinect-like webcam and the Space Invaders project a friend and I’ve been developing got through to the second stage. This is a project that we have tried making on several platforms and interfaces, but the original idea persists: remake the classic game in 3D, where you are the controller and the invaders and their space is as big and immersive as possible. Below a short video from the beta.

And here is a video from our alpha stage with the kinect a year or two ago.

Cargo Cult at Burning Man

Cargo Cult at Burning Man

We should ask for some Norwegian cultural-petroleum monies and go to Burning Man this year…

Our story begins in Melanesia during World War II. Thousands of American GIs suddenly descended on this South Sea island chain, bearing with them unimaginable riches: magical foodstuffs that never spoiled, inconceivable power sources. Just as abruptly the troops departed, leaving only broken, rusted Jeeps, crumpled beer cans, and the memory of Spam. To the astonished eyes of the natives, this was a miraculous occurrence, and they yearned for the return of abundance. Accordingly, they built totemic sky-craft in an attempt to summon back these Visitors and their legendary leader, the man the Melanesians called John Frum. They had formed a Cargo Cult.

Violet Ray

I found this beauty on a marked in Fredrikstad on a family holiday:

I had no idea what it was but instantly fell in love! A few hours of research (AKA Googling) later i realize I have bought a pre WWII miniature Tesla Coil to stick up my ass! How cool is that!

The device is a Helio Lux Violet Ray Electro Therapy kit with a large variety of electrodes, including Eye Socked Electrodes, Anal electrode and Spinal Electrode. These devices was used for health care in the late 1930s but are now adopted by the BDSM community.

We have off course already given it a run at the 220Vs but, as expected, the device is completely dead. A look inside revealed a broken fuse and a shorted primary cap 1uF/1000V. This is now ordered from RS-components and my guess is that it’ll do the trick.

One question remains though; is the Noble Gas in the tubes still present after so many years..? Update will come when the cap arrives!

Update: Cap has arrived:-)

Animatronics for Teater Avvik

Lars Vik of asked me last december if our robot, Dr. Bürhool (AKA Nille), could be used by Teater Avvik to create a performance for children. Dr Bürhool is already an experienced actor after two seasons of “Bråta” in Porsgrunn.

Anyways, he also wanted a kind of Nilfisk (the Brand of the vacuum cleaner used for Bürhool) univers, with more stuff to play around with. So I made him Willie and Ada. The story to be told is about a groundskeeper, Bull, taking his favorite inventions on the road after loosing his job.

Here they are, Nille (Bürhool), Willy and Ada.
