Die neue Webseite von Lisa-B ist online:  www.lifelike-figures.com

Dieses Webprojekt wurde mit dem WordPress Blog-System realisiert.  Dazu wurde ein Template entwickelt, um die speziellen Layout-Funktionen zu realisieren. Die Info-Seite enthält Unterseiten mit animierten ‘Popups’ (Pop-ins?)

Den Kern der Seite bilden animierte Bildergalerien zur Darstellung des Portfolios von Lisas Arbeiten.

Comments Off on Neue Plugins im Synoptx-WordPress-Paket

By TeK, April 6, 2011 14:30

Bei der Entwicklung einiger WordPress-Internetseiten ist uns aufgefallen, dass diesem CMS ein paar Funktionen fehlen, die (inzwischen) wirklich jeder verwenden möchte.
Wir haben daher diese beiden Module entwickelt und integrieren diese von nun an neben weiteren Plugins auch in unser Standard-Wordpress-Paket:

Social Media Buttons
Facebook, Twitter, Xing, Delicious, MrWong, Linkarena und viele weitere Icon-Links als frei konfigurierbares Widget.

Metatags Plugin
Das WordPress System bietet nur die Möglichkeit, den Seitentitel mit dem Titel des Artikels zu versehen, aber es fehlen Felder für Keywords und Beschreibung, sowie die Möglichkeit, für jede Seite individuelle Werte zu setzen.

Dieses Plugin ermöglicht die Bearbeitung dieser Metatag-Felder für jede einzelne Seite und jeden Blog-Artikel:

• <title> – Titel der Seite (wird in Suchmaschinenergebnissen angezeigt)
• Description – Beschreibung
• Keywords – Stichwörter

Das Plugin bietet die Möglichkeit, diese Metatags für beliebige Sprachen zu setzen und diese im Template-Quelltext zu integrieren.

Open Source Release
Beide Module sind Eigenentwicklungen von Synoptx.net und werden in Kürze auch als OpenSource (GPL Lizenz) veröffentlicht.

Comments Off on Icecast, Rails, ntop, etherpad,… via Apache Webserver: ProxyPass

By TeK, January 12, 2011 01:23

A quick tip, how to map web-apps on random ports to the main apache webserver. This way you can run these services on subdomains or sub-directories and support SSL encrypted  https connection, even if it is not directly supported.

Take care to not open a proxy for everybody or it can be abused by spammers. “ProxyPass” combined with “ProxyRequests Off” is save.

If the original port is not used anymore, it can be closed in the firewall. Only for the icecast stream it is s useful to keep :8000 open. By mapping to an internal IP a address of a virtual machine, you can also forward to vservers.

The admin webinterface on /admin/ can be redirected by mod_rewrite to a secure SSL connection.

Example: Icecast ProxyPass to map webinterface on port 8000 to apache subdomoain (port 80)

<VirtualHost *:80>
   ... # your vhost here: ServerName, Logs, etc
   ...
   # Proxy ACL
   ProxyRequests Off
   <Proxy>
      Order allow,deny
      Allow from all
   </Proxy>
   # Proxy directives
   ProxyPass / http://192.168.1.7:8000/
   ProxyPassReverse / http://192.168.1.7:8000/
   ProxyPreserveHost on

   # redirect /admin to https:
   RewriteEngine On
   RewriteRule /admin.*  https://tv.example.com:443/admin/ [R]
</VirtualHost>

Example: Icecast ProxyPass to map admin webinterface on port 8000 to apache subdomoain (port 443)

<VirtualHost *:443>
   ... # your vhost here: ServerName, Logs, etc
   ...
   SSLEngine On

   # Proxy ACL
   ProxyRequests Off
   <Proxy>
      Order allow,deny
      Allow from all
   </Proxy>
   # Proxy directives
   ProxyPass / http://192.168.1.7:8000/
   ProxyPassReverse / http://192.168.1.7:8000/
   ProxyPreserveHost on
</VirtualHost>

There was some disc space free on a server and so we collected CCC Congress videos of the last years:

• http://ccc.synoptx.net

You can watch the talks directly in the brower

or start a player-program like vlc or mplayer with the http:// url

or download the file with “save as..”

Demo Video of the “moving projection” video installation at Suchtfaktor elekto party in MIKZ, Berlin 03.2010
Monthly, every 1. saturday, also in 2011!

The “MirrorBot” is a Arduino minicomputer system to control the position of videobeamer projections. Two servomotors move a mirror in X- and Y- axis, which reflects the beamer image. The servos are controlled by a micro-controller with an LCD. It can play various movement pattern programs automatically, adjusted to the music speed by setting BPM or ‘live’ with the joystick and button.

Headsquatter VJs use it to move visuals around the whole dance floor when playing in clubs. Moving projections become a live instrument! 😀

Comments Off on Video: PONGuino – Arduino & S65 Shield – 2 Player MiniGame

By TeK, December 27, 2010 04:55

Here is a video about the PONGuino game for 2 players on a minicomputer with mobile-phone display and joysticks.
The box contains an Arduino 2009, a S65-LCD Shield and a gamepad from an old playstation 1. It runs autonomous on 9V battery.

The device is originally built for the “Mirrorbot” moving projection system [ lab.synoptx.net/mirrorbot ], but the pong-game-code from www.codetorment.com was perfect to test the LCD and – really – it’s fun to play!

The system is just fast enough to play a game, but you have to take care, how many pixels and how fast you draw. There is no double buffering and just a serial line between arduino and screen……

more info in this post from 02.2010

Sorry for the low quality photo-cam recording.
The LCD is not bad in reality: You don’t see the pixels and the scratches are only on a transparent folie..

Comments Off on Arduino Workshop “Hardware 2 Software Interaction” Level #01

15.11.2010 @ nerdcafe FHain LUG    nerdcafe.vetomat.net

Workshop Info

Hardware Hacking -DiY — Introduction to Hardware <-> Software Interaction

This introduction is intended for anyone interested in (easy) electronics hardware and (mostly easy) software coding. Artists / *Designers & Hackers of all kinds are invited to join the FREE sessions in Berlin Friedrichshain.

TKilla will introduce the Arduino micro-controller platform and show some practical examples. Basics of electronics and some interesting components will be explained shortly, but there are no tricky mechanical works and no soldering involved.

We will focus on software programming inside the Arduino editor to show how to read analog values from various interesting sensors and output to LEDs and maybe servo motors.

To get some interesting visual results, we will use Processing to display incoming values from sensors in graphical ways.

After the lesson, you should have an idea how to design & build your own simple robots (servo motors…) or sensory controllers (MIDI / OSC faderboxes,..).

If there is time, everyone can install the software and try with a board and sensors. We can focus on special topics and the workshop part (maybe MIDI Controllers) in a follow-up evening.

Synoptx Crew organizes all material, tools and a nice location.

Max. 5 Arduino boards will be available, so bring your own, if you have one or contact us by mail or comment..

BYO laptop!

and interesting electronics (sensors) to recycle! (old joysticks, buttons, potis, faders, sensors,…)

27.09. – 19:00

nerdcafe.10247.net

This lecture is an introduction to git, mainly from client-site,
but some tricks for servers to control access are also introduced (gitosis).
Furthermore, with git-svn you are able to reach a svn-repo via a git repo.
