Embedded audio hacking
Today I took receipt of two Adafruit wave shields - kits which let your Arduino read and play audio from an SD card.
These kits will be used in the Second Salon exhibition which starts later this month in which I'm showing the hauntology work. I'm planning to rig them up to sensors which will detect movement in the gallery and play sounds in response.
In particular I'm looking at using several sensors dispersed through the building, which when triggered together will fire a set of sounds through the building's tannoy and into the ears of not only the gallery visitors, but the people getting on with their working lives elsewhere in the building.
More details and code here as the piece is constructed.
