Hall im All – Satelite Fishing in Tirol 25.7.2014

It has been a while since we did that, and now Kulturlabor Stromboli, a cultural center in Hall in Tirol, a small town close to Innsbruck, has Space as its celebration topic – and of course we join!

This time, it is Reni Hofmüller and Norbert Math, who get together and set up a fishing environment in Hall; for the first time we do it at dusk into the night, and hopefully will not only hear, but this time also see some satelites!

Microwave Festival Hongkong November 2013

Jogi and I visited Taipei and Hongkong in 2012, and met Ellen Pau, a media artist, founder of Videotage and a central figure in the support for art in this reagion of the world.
During this visit to Hongkong in 2012, Jogi and I gave a satellite fishing workshop, each time an amazingly personal and intensive encounter with our understanding of technology and impact, a direct body connection can have.

The visit in 2012 made quite an impression on some of the people in Hongkong, which led to the invitation to participate in the 2013 edition of the Microwave Festival.

Things About Orbits

Whenever we present the satellite, a lot of questions regarding orbits, speed of orbital bodies and these things arise.  XKCD has nice answers to some of these questions in one of his recent articles of his what if? series.

Satellite Fishing At Kleylehof

satellite fishing preparations

Preparing the satellite fishing workshop at Kleylehof/Nickelsdorf

This year we were invited to give a workshop at the annual reheat festival organized by klingt.org at Kleylehof/Nickelsdorf.  The topic was satellite fishing and that’s what we did.

We brought our mobile equipment consisting of two laptop computers, a funcube dongle and a handheld antenna.  Softwarewise we stick to qthid for tuning the dongle and quisk to decode the signals.

We were unlucky in getting beacons from various amateur radio satellites (and the ISS) this day.  But when the NOAAs started to arrive we got some pretty good readings from their APT transmitters.  And this time we did manage to decode a data stream and got our first image from NOAA 15, decoded by using the free version of wxtoimg.

Thanks to OZ9AEC’s blog we finally managed to feed a correctly formated sound file to wxtoimg and got rewarded by the image above.  Since nobody cares to mention the basic facts I do it here:  set your decoder to AM and try to get a clear signal.  Then follow OZ9AEC’s instructions on howto prepare the sound file before feeding it to wxtoimg.

It was great fun to be at reheat!  Once you manage to find Kleylehof you just let go and enjoy the spot.  The klingt.org people are super friendly and the festival is a cool place to be.  Despite the occasional drizzle and falling temperatures it was nice to be outside all of the time and see all the different performances and installations.  Go to the reheat 2013 image gallery for an impression and be sure to save the date for next year!

Worklab X Sat, 27th – Mon, 29th of April – mobile satellite tracking station


We have had this idea for a long time already – that it would be nice to go out and have a good compact satellite tracking and listening possibility. Our favorite in this is a bicycle-trailer, a box with 2 wheels to adjoin it to a normal bike.
We will look into antennas and also into energy harvesting, to make it light, easy to use and fun to experiment with.

AIRFLOW premieres at Interpenetration Festival Graz 13. – 15.12.2012

Sonifications of a video from a weather balloon flight – we have had this idea since long and now it is ready and we premiere the 23 pieces at the Interpenetration Festival Graz 13. – 15.12.2012 in forum stadtpark graz.

The background: we want and actually we need to test the communication module that will be installed on mursat1 to be sure that it does what we want it to do. The best way to do this is to mount it on a weatherballoon, because we can retrieve the hardware after the flight. Equipped with a special GPS-transmitter that has a broader range than normally (more than 10km), it can be found after landing back on earth. We got the video recording from July 2011 leaving Graz, from OE6XAD, Transmitter Dobl with special support by Hubert Tschugmell, OE6THH and Christian Lammer, OE6LCF.

Richie Herbst, Maru and I came up with a system: we cut the video in 23 snipets and offered them to about 30 musicians to be inspired by the imagery and sonmify them. This is the list of participants.
