ep-4yy13 DSP – week 13

“I think its just the biggest conceptual art project uninentional or otherwise that anyone ever made. it puts Christo and those other guys to shame. Its planetary”

Roman Mars “Episode 97 – Numbers Stations” from 99% Invisible

Radio

  • Measuring the invisible
  • What is the difference between sound waves and radio waves?
  • What is an antenna?
  • Wave propagation is frequency dependent
  • Sunspots and magnetic fields http://spaceweather.com
  • Extreme frequencies, negative frequencies?

examples

Internet radio streams and recordings

Frequencies and modes
  • Macbook trackpad: Noise 5 mHz. (try holding radio near screen too)
  • Macbook AC adapter: Noise 600-1400 kHz. (~1000)
  • AC adapters, LED’s, Utility poles: 3.2 Khz
  • Arduino transmitter: AM 1330 kHz.
  • Laser light at 650nM
  • Wireless micorophone (Orange-brown): Wide FM 614.150 MHz. (R band)
  • Cordless phone: Narrow FM 926 mHz.
  • Cell phone: Digitally encrypted trunking FM 836 mHz.
  • Wifi: Digitally encoded PCM 2.4 gHz.
  • FM broadcast band: Wide FM 89.7 mHz (Raspberry Pi example 98.1 Mhz)

ep-4yy13 Notes for DSP Class 4/16/2014 – week 11

Prototyping

Favorite tool of artists and engineers

How to make prototypes

  • Talk to people about your idea (but don’t let them talk you out of it)
  • Use Google as a research library
  • Learn to hack computer programs (you don’t need actually to write one) Flappy Bird clones: https://reactivemusic.net/?s=flappy
    • Github
    • Terminal (Linux)
    • Text Editors
  • Read manuals, blogs, forums, and academic papers
  • Make things
    • Arduino, R-Pi, breadboard
    • Lego, cardboard, duct-tape
    • recycling
  • Max, Pd, Processing, HTML5
    • Max for Live
    • help files
    • externals
  • Reverse engineering (Leap Motion Bloom thing https://reactivemusic.net/?p=9135)
  • Show your work: videos, writing, open source…

How to get ideas

Thoughts about the music business, 2014

  • Solve someone else’s problem
  • Making connections
  • Online portfolios
  • Try hiring yourself

Assignment

The final project for the class: build a prototype

  • answer a question
  • solve a problem
  • prove a concept
  • build a small part of a bigger idea

For next week, please send me, or tell me what you will be doing: A sentence, a paragraph, a drawing, an “elevator pitch”. This is an important part of the process because I will decide whether you get funding to continue your work 🙂  You can always change your mind about what kind of prototype to make up until the very last moment.

The entire project will be due on the last day of class for the semester.

It can be anything relevant to the work you are pursuing, perhaps a machine, a dream, an idea for a new type of composition, a way to connect things, an instrument, a piece of music you will pitch to get a gig, or part of a proposal to submit, an idea for a business, a solution to a problem, an experiment (think science-fair) – Mostly it should be an idea you are excited about.
