Metzwerk

Just wanted to announce the auction of “Aufstand der Dinge” on Sunday, 22. of March, 17h at Gallery SAKAMOTOcontemporary. You’ll be able to buy the whole world by passing by – or bidding online. You can even buy our Pylofon and some other machines we’ve build!

Thanks to german SPEX-Magazine for publishing a detailled and nice article in their Blog. It’s not only about “Aufstand der Dinge” but also describes some other things we did.  We don’t completely agree on being called “Extrem-Geeks” – but thats how press business works.

As well we  wanna invite everyone to Neoangins / Jim Avignons Concert on Sunday 25th at 19h, Gallery Sakamoto. Its going to be the Releaseparty for Yukihiri Taguchis new music-video (we already saw it, great work!)

Opening of \

Our art-installation went quite well last Saturday. We’ve been working the whole night through building and programing and made it work in the very last minute. Well, almost work. Due to some strange Arduino-problems not everything was as interactive as we wished – but you wouldnt notice until you know it.

Thanks to everyone who came (about 400 People!), it was a great evening. Kaspar already posted some pictures on Flickr. We’ll improve the interactivity of the installation in the coming weeks and will post more details about some single machines / cardboard boxes as well.

If you live in Berlin- we invite you on the 25th of January. Yuhihiro Taguchi who showed his wonderful installation and stop-motion-movies at Sakamoto-Gallery before we entered the space will create a music-video for Jim Avignons one-Man-band Neoangin and present it around 6pm. There will also be a Neoangin-concert and we plan to make the machines dance to the rhythm.

Aufbau Aufstand der Dinge
(Day 2 of 7: filling the boxes)

Here you can see the world – and us creating it. Together with our friend Jim Avignon we’re currently putting together a mountain of cardboard-boxes and a real lot of fancy electronic gadgets (including 15 servo motors, 2 wiimotes, 2 arduinos, an old cash-receipt-printer (which tickers twitter), a tikitag-RFID-Reader, an old Atari-Joystick, a gembird switchable power-bar and much, much more.)

In the end there will be a controllable world-map (11 x 3-meters) and an arty ehibition called “Der Aufstand der Dinge” in SAKAMOTOcontemporary Gallery, Oranienstr. 164, Berlin-Kreuzberg. Its obviously about things and tools regaining control and theres more info in german on the gallerys site.

This is by far the biggest thing we’ve ever build. We’re hoping to be finished till the opening on saturday (18pm) – and to find some time to tell you more about the technical side of the project. Hopefully we also get our webcam running as soon as possible.

the one-hour laserbeamer

Januar 3rd, 2009

Laserbeamer

Last month Kaspar put a cheap laser-pointer onto two servos and programmed a driver for it within one hour. This way he can paint pictures on the wall. Disatvantage: they can only be seen through a long exposed cameras lens as it takes about one minute to paint all the pixels.

Anyway the small laserbeamer was first uploaded on flickr and quickly mentioned on Hack a Day where many people posted their comments and suggestions for improvement. Thanks!

Here is a deeper technical description:

it consits of a 5v laser module and two servo motors hold together by cable straps and is controlled trough a pololu serial 8-bit servo controller by some python code.
the laser module is simply switched trough the serial ports DTR line, that gives pulses as fast as the serial connection speed.

Let us know if you’re interested in the Sourcecode. And: Next time we’re going to post things like this on Metzwerk first. Promise.

The Pylofon

April 3rd, 2008


The Pylofon is a wlan-xylophone-robot which can be controlled by internet – but as well by cellphone or a Wiimote. It also plays MIDI-files and time-scheduled random sounds.

We build it in two nights at easter 2008, using 2 Graupner Servos, a 99c-xylophone, a cardbord-box, an Asus WL500gP-wlan-router with OpenWRT Kamikaze and Python 2.5, SSH, a Pololu Serial 8-Servo Controller, an USB to Serial-Adapter, a Bluetooth-Stick and a USB-Memory-Stick.


The Pylofone, Demo I


The Pylofon-Drum-Section, still practicing

Next plans: a better demovideo, web-interface, RSS-import, live-MIDI, drum-section, mode-switch and gpl-python-sourcode.

Livecasting re:publica

April 1st, 2008

Auf der re:publica ‘08 wird sich Kaspar um das Livecasting kümmern. Es heißt nicht Streaming oder Podcasting, weil es neben den MP3-Livestreams und den Podcasts auch mitwachsende Echtzeit-Mitschnitte geben wird, die sofort, also noch wärend der laufenden Veranstaltung, abgerufen werden können.

Das dahinterstehende Livecasting-Serversystem hatten wir erstmals auf dem 9to5-Festivalcamp eingesetzt und nun weiter optimiert – so werden nun z.B. die Metadaten der Mitschnitte direkt aus dem Pentabarf-Veranstaltungskalender übernommen.

5 laptops and many visitors

März 27th, 2008

Last week Kaspar shot and published this photo on flickr – soon it got posted on the make blog which made it climb on reddit too.

Actually the most interesting thing is not the photo (inspired by the transparent screen pool on flickr) – but how fast you can reach more than 65.000 visitors within a couple of days.

very hot chip

März 12th, 2008

We repaired a damaged Apple iBook G3 by heating up its graphic-chip to more than 200° celsius with a cheap heatgun. The amazing howto on Geektechnique was right – after three times heating and re-soldering the pins, the notebook started working again!

Hello SMS Jukebox

März 1st, 2008

Hello SMS Jukebox is an interactive horoscope for partys and vernissages. People can ask all kinds of questions by sms, adding their name and birthdate. The Jukebox then blinks, a character repeats the question on the screen and the horoscope, personalized by a clever fox, gives the answer.

We built the SMS-Jukebox using: an old Nokia 6310 and a datacable, Gammu to submit the SMS to a MySQL-Database, PHP for the Horoscope-Backend and XML-output, Python and MaryTTS (thanks to Universität Saarland for their fast TTS-Server!) to generate the voices, XML and Adobe Flash to display everything on the screen. The Flash-Part was written by Barbara Rauh and the style, music and characters were created by Jim Avignon. The holy (and secret) horoscope itself lives in Scotland and Berlin.

So far we’ve had fun presenting the SMS Jukebox in Athens (Goethe Institut), Berlin (Haus Schwarzenberg), Luzern (Fumetto-Festival), Munich (Jörg-Heitsch Gallery) and New York (Deutsches Haus).
