Article in L'Actualité

We're really glad to be onboard this project led by Nicolas Reeves at UQAM (Université du Québec à Montréal). Onboard is the right word... that was a pun actually. This project consists of flying cubic ballons, inflated with helium, controlled by an embedded tiny-tiny computer. This is a great example of what's going on in this new discipline called robotic arts.

Song of a maple

This is a project created by Lorella Abenavoli, a psycho-acoustic sculptor. She dedicates her work to making audio pieces off natural phenomena. This one is about recording the rise of sap in a maple and transforming the recording into an audible artwork. Rise of sap is a complex process. First issue is related to frequency: we're dealing with ultrasounds in the 500KHz-1MHz range, which requires very specific devices such as hydrophonic microphone and ultrafast acquisition card. Second issue is storage: to have a good quality of signal and make sure there's no loss while recording, we have to sample at 2MHz * 16 bits = 32 Megabytes/second (1 minute=1,8 Gigabytes). Next issue is transfer of data. And last issue (but not least), processing. This one is for Lorella! Here's a screenshot of what it is that our application does.
