Robot House Music Makespace Stgo de Chile from the 8th to 11th of July 2013

Robots work in the industry, help in households, play football – or make music as an orchestra!

I will conduct a workshop where an open group will create THE HOUSE ROBOT ORCHESTRA.

People tinker, hack, fix, reuse, and assemble materials in creative and unexpected ways, often codifying and sharing their production process with others. Do-it-yourself (DIY) encompasses a range of design activities that have become increasingly prominent. DIY practice is not only a set of methods, but communities, new values, impact in the domains of traditional crafts, technology development, and sustainable design.

The workshop will comprise the further development of the ongoing project The Robot House Music Orchestra. This is meant as a collaborative approach with people from all ages and all backgrounds.



In this workshop, participants build and play with a simple, modular and fully analog sounding robots. The basic circuit generates interlinked sound output and has a completely modular, voltage-controlled architecture. This means that it can produce single-voiced drone or can be combined with other units to make complex swarms of drone and signal feedback interaction. Participants in the workshop build their own circuits to take home. Through this process participants discuss how and why the whole thing works.

The goal of the workshop is an audio performance with all the created robots

Reasons for the projct are knowledge, new skills, and the enormous feeling of satisfaction that comes from building your own equipment. For younger people, the skills learned will be invaluable as you progress through life, and once started, you should continue to strive for making it yourself wherever possible.

Each and every new skill you learn enables the learning processes to be 'exercised', making it easier to learn other new things that come your way.

Alvin Toffler (the author of Future Shock) wrote:- "The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn."

The workshop is about the creation of a robot orchestra, where sound synthesis and composition are set by light, graphics or pictographs.

No previous skills are needed.

Newbies are welcome.


Light will be used to change the frequencies. In some cases, the relationship between what you hear and what you see will be very obvious, in others it will be less obvious or not at all. A modular and DIY approach characterizes this work. I am keen on destabilizing preconceptions of role and function as well as dissolving the barriers between producer and consumer. Particularly to this end, I employ the practice of electronics hacking and circuit-bending of common technologies to illustrate that function need not be dictated to the end user.

Robot House Music has been inspired by Daphne Oram, whose pioneering achievement, a synthesizer she built in the late 50s, is almost forgotten. She is best known for her design of her Oramics system. She developed her Oramics ‘drawn sound’ system, which consisted of a large machine that enabled patterns drawn on transparent 35mm film to be converted into sound.

  • 1pcs 2N3906
  • 1pcs 2N3904
  • 1pcs capacitor 0.1uF
  • 1pcs loudspeaker ~32 Ohm
  • 1pcs LDR photocell
  • 1pcs reflex coupler CNY70
  • 1pcs resistor 330 Ohm

e.g. LDR07.png

Line Follower

e.g. G123240A.jpg

  • heavy wire
  • hot glue and a hot glue gun
  • red, black white wire
  • 1pcs 9Volt Block
  • 1pcs battery clip
  • cutters
  • soldering irons
  • solder

No breadboard, no PCB, all free form



Wikipedia on Line Follower Robots


BC337, the BC875 should be replaced with the BD697 (same layout), 330 Ohm, 5,6K

Flip Flop

Control, actually a Flip Flop circuit. To connect external circuits (e.g oscillators) you only have to attach their minus pole to the unconnected pin of T2.


T1,T2 BC546, C1 470uF, C2 2200uF, R1 220Ohm, R2 10k, R3 1k, P1 10k, D1 Standard LED, D2 1N4001



2N3904, 2N3906, 0,1uF, LDR, 330 Ohm

The minus pole goes to the Flip Flop (remember between T1 and R1 or T2 and R2)

You might want to replace the CNY 70 reflex coupler with an LDR or other resistors or potentiometers.
