The singing dunes

Simulation of mysterious dune sound.

by Raz Mesanai

Using Ableton Live instrument racks.

Here’s an attempt at replicating the set. Start the clip. Adjust instrument rack dials, or play using Midi: singing dunes

We copied the settings from screen shots in these videos:

Astronaut Drives Lego Robot Via ‘Interplanetary Internet

11 Cool Tools NASA Curiosity Brought To Mars

“The test used NASA’s Disruption Tolerant Networking (DTN) protocol, which the space agency a decade ago jointly developed with TCP/IP co-inventor and Google VP Vint Cerf. The technology can withstand delays and disruptions that might be common in space due to long distances and obstacles like planets and solar storms. Unlike Internet Protocol, which establishes an end-to-end connection before sending data, DTN moves data node-to-node, and can wait for connections to open up before relaying information to further nodes.”

Wheel sensor , from a wired (not wireless) bicycle speedometer (aka cyclocomputer) The sensor must perform like a reed switch, which is binary, rather than use the magnet on the spoke to vary the inductance. We used a Sigma Sport BC 500, which costs $15, but the city of Portland gives them to residents free, to encourage bicycling! Ask a bike shop if they can sell you just the wheel sensor part, without the computer and display.

Measuring rotation

We are trying to measure RPM of a bicycle wheel by reading the accelerometer data stream of a Wiimote wedged between the spokes of the wheel.

When the wii-mote is in the bicycle wheel it generates a stream of numbers much like a sine wave. Lets say we want to just get the speed of the wheel. It would be the frequency of these ‘sine’ pulses.

Strategy: use [past] object send a bang once each cycle. Then use a tap-tempo patch to convert pulses into bpm, mph, etc.,
