Maker Faire

Maker Faire in Trondheim! We had a mini-maker faire last year. This year, the fair took over the torg, with many, many booths with exciting uses of robots, design and technology. Some of my favorites:
A robot that plays piano. Also bananas that you can touch and play like a piano.

These Cthulhu-like creatures were "designed" and printed by an AI. Fear the future!

One stand continuously printed and gave away whistles. Lots of 3d printing here.

This sculpture is... I don't know what it is. But it's cool. And made by kids.

Peter building with Strawbees, a Kickstarter project.

Octocopters. A friend of mine is building one with 48 rotors that will be capable of lifting a human. Ooooh yes.

Battle bots! Remote control robots that fire foam missiles at each other!

A 3d printed trillobite. Cooooool.

Autonomous problem-solving robots.

Bendik and his bizarre and wonderful wedding cake. See video below.

Zenta, aka Kåre Halvertsen, builds amazing robots. See yesterday's blog posting for something really cool.

Maker fair fest

I ran into a friend who is running Maker Fair in Trondheim this weekend, and scored an invitation to the maker fair party that was being held at the Science Center. What a treat!

Roger Antonsen addresses the party

The highlight was a demonstration of a rolling, transforming robot built by Zenta, aka Kåre Halvardsen. Here's a few clips of video I took of the robot:

And here's Zenta's offical video if you want some more:

I took the Hurtigbåt (speedy boat) across the fjord today. This boat leave from Trondheim city center every hour (mostly), and is a fast way to connect to the other side of the fjord. We are in negotiations to purchase some property across the fjord, so this could be an important connection for us.

The boat was surprisingly full. A lot of people it seems live across the fjord and work in Trondheim. Parking is free on the other side of the fjord and you can bring you bicycle on board the boat for no charge. I may be doing this a lot in the coming months!

The trip costs about 90 kroner ($15), or a month-long pass is 1729,- ($272)

Here comes the boat!

We went for a walk down at Ladevikhammeren this evening. Here is the giant "gigaphone" (1000x megaphone, get it?) It has crazy acoustics. When it was first released it was in city center, but now it has been moved by the water where it points directly at Munkholmen, the island out in fjord outside of Trondheim.

The gigaphone is now covered in graffiti, which given its location adds to its charm, methinks. Interesting in this pictures how the graffiti shows up so starkly when viewed in one direction but not the other, thanks to lighting by the setting sun.

New wall

Peter dug out the back yard, deep into the clay cliff behind our house. Finally, under Pam's relentless determination, the area is flat and wide. I stacked stones and rebuilt a wall. Very satisfying. Much to do still, but our house is slowly coming together. We now have a new area behind the house that did not exist before. Nice!

I had the honor of giving the Math Encounters talk at the Museum of Mathematics (MoMath) in New York this month. My talk entitled "Naked Geometry" was well-received with two packed shows.

There is a fine beach not too far away at Storstrand, between Ranheim and Hommelvik. We went for a picnic today to enjoy the fine weather and maybe – maybe! – swim a little.

There is a children's skatepark, hundreds of plum trees, and an ice cream shop in the area. It's a lovely place to spend a summer afternoon.

Stark contrast between the beach and the rocky area.
