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

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.

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!
