Recycled Hard Drive Instrument - Electric Waste Orchestra
Creating unconventional musical instruments from outdated computer parts and other e-waste
In the hubbub of Moogfest, we serendipitously ran into a guy wearing purple 3D-printed eyeglasses and holding something that looked like a keytar. Upon closer inspection, and with the house lights turned up, it turned out to be a musical instrument made from outdated computer parts. Colten Jackson wasn’t a speaker at the festival, but a passionate musician who made the trek to Asheville from Champaign, IL, to spread the word about his educational side project, Electric Waste Orchestra. Jackson reuses e-waste to make music in unconventional ways—for example, in this video he transformed six hard-drives and a number pad into a musical instrument (with help from Arduino hardware and Pure Data software) and jams along with a modular synthesizer.

Meet Elif Bilgin, the 16-year-old winner of the Scientific American Science in Action Award and winner of the Voter’s Choice Award for the Google Science Fair 2013.
Wanting to reduce pollution in her home city of Istanbul, Elif manufactured a new environmentally-friendly bio-plastic that uses banana peels - an organic material - instead of traditional petroleum sources.
What does this project explore? You can learn about a tree’s growth and history by observing its rings. Scientists have been able to use the information from the sizes and spacing of tree rings to identify climate change. These studies can also identify trees that are suffering from the early stages of pollution effects or can identify an area that is not getting enough irrigation. Past climate conditions can be discovered and future climate patterns can be predicted from the study of tree rings.
Make a slow-drip watering system. Most plants like their roots to be damp, but not muddy. This experiment is perfect for observing how plants absorb the nutrients they need to thrive. Check out the rest of these 12 Gardener challenges.
