The arduino touchscreen shield by watterott.com :: URL? is great fun. TKilla built:

• MIDI Controller for VJing and Audio-Studio
• PONGuino-touch – 2 player touchscreen game
• PC remote control with mouse- and keyboard- econtrol, VLC mediaplayer control,…
• various tests/demos

Infos, Code, Videos & more pictures coming soon

Comments Off on Tool of the week: k4dirstat

HeyHo, the disc is full, the disc is full…, but i found a great help:

“KDirStat – Directory statistics.

Shows where all your disk space has gone
and helps you clean it up.”

Installation in Debian and Ubuntu:

$  apt-get install k4dirstat

I think the screenshot says it all:

Every cube in the tree-map illustration represents a file or a directory. By their size its instantly visible where all the space is used up. You can click the big blocks to get a direct link to the file in the tree.

Mirror Bots .: moving visuals projections – standalone & Linux GUI controller

This is a robotic system to move VJmix projections all over the walls.

Beamer projection reflection on mirror

Mirrors are mounted on servo motors to rotate them in front of dia projectors or beamers. This way, the projections are moved across the walls and the ceiling of the room.

A microcontroller system, connected to a netbook, is used to control the mirror-servo-unit movements.

“Hotspots” are defined to project on the best spots on the walls of the location and create an impressive light show of moving rays and projections on all walls and screens.

1.prototype live action with diaprojector & beamer

This system can be installed in rooms of any size.

It is required to use projection glass or there are double projections and very unsharpened results. The beamers must be powerful to show bright images also on the must distant walls. In big rooms, the projections are really big, so the 2 video mixes can work together as moving textures or moving characters.

The proof-of-concept system was first used by Headsquatter Live Visuals in Berlin @MIKZ – Suchtfaktor – 27.09.2008 with great success and continuously enhanced and tested live.

Hardware

We use a common, programmable input/output hardware controller to trigger motors: Arduino Dicemilia.

1.prototype live action -- only left dia is mirrored

Two Mirrors are mounted on  servos to move them in front of two video beamers. This first version can move 2 projections with 2 mirrors on one horizontal axis between 40° and 130° – ca.  It  creates distorted projections depending on the current angle, but works very well with various kinds of video mixes. High contrast images and vectorial animations work specially good. By positioning two projections besides each other there appear many interesting possibilities.

Combined with fog machines the rays become visible and the moving beams look like a laser show with real videos.

The servo-mirror movements are synchronized to the beat of the music and many programs can be selected, to move the projections in various patterns.

VJ Live Mix Box: Wiimote - VJ mixer - Arduino Servo Control - Mirror (+ eeePC 🙂 ) - Linux Netbook

Software

This MirrorBot is controlled by a linux netbook over serial console via USB cable. The prototype is remote-controlled  by a simple software command line. Various keyboard key presses change program, speed, play/pause mode of the attached servo control box. This works quite good during live visuals mixes, with a mini terminal window in front of a TVtime preview screen of the video mixer.
