Media Art Installation - Technique 5
For the interactive drum robot installation “MR-808 Interactive” we need interfaces that control this art installation. We choose Nexus 7 2013 (second version) Tablets as they are cheap (ca. 120€ at Ebay) and easy to use. On them we open a web-based drum sequencer that controls the physical moves of the robot in realtime. (more…)
Sometimes it is not possible to stuff all the hardware for a live performance into a Macbook. Then you need a real PC. But it shall be transportable. Without too many cables. Easy to setup. With everything insode .. well, like a macbook.
For our glitch robot project we needed a PC to handle the video date. And so we build our OWN laptop!
‘Madcam‘ is an open frameworks (C++) based project for mixing USB Web Cameras (e.g. the 10$ cheap PS3-Eye web cam) im realtime. Why this is awesome? Its usually hard and/or expensive to mix many video signals in realtime and display them side by side. We found a way to make it cheap, quick and reliable!
The project is a visual extension for another awesome project called “Glitchrobot” where Robots are used to make electronic music, but thats another issue. Lets start!
The goal is set up an VJ setup which is based on live webcam material. One webcam? – Boring! 10 Webcams? – “Unlimited” fun! (more…)
The music robot “Glitch Robot” aims to produce sounds used in electronic music. It is referencing to glitch sounds – or Clicks ‘n Cuts – a sub genre of the electronic music.
I started with the imagination of what sounds I would like to use when producing music. What percussion sounds does a music track need? Escpecially if you’re into glitchy sound of the infamous clicks n’ cuts era. If you don’t do minimal techno, you need more than a phat bass drum & Hihat. (more…)
When combining different robo-mechanic instruments and let them jam together, the most crucial point (beside from making awesome music) is to set the latencies right. The setup is mostly the same: we have a robotic music instrument (e.g. a snare with an solenoid actor), a somewhat electric power unit (Relay, Motordriver / FET-drive and an Arduino) and a unit to generate the information, e.g. keyboard or a midi-program like Ableton.
Each instrument has its own unique latency, given by the time between the “note on” signal (e.g. Ableton triggering a note in the sequencer), and the time when the tone finally leaves the physical instrument. These latencies can be up to several 100 microseconds, a delay that a human ear will definitely recognize. The latency consists of (more…)
