Field notes

The site is organized into Music, Tech Projects, Odyssey of the Mind, Nonprofits, and a deeper “More” section, with links to performances, app listings, articles, and research. Its Isoyue description names an AD8232 heart-monitor board, Arduino Uno, and Max/MSP, and says ECG is sampled at 250 times per second before heartbeat variability informs the composition. The page also says Beddr development followed interviews with more than 30 students, parents, and teachers.
