You don’t have to be from Milwaukee to take part in Maker Faire Milwaukee. We’re excited to welcome back our friends from Pumping Station: One in Chicago who will be offering to help you build your own “PS: One Noisemaker”, which is an optical theremin. What’s a theremin you might ask? It’s a musical instrument controlled without physical contact. Typically you wave your hands in the air to create sounds. The “optical” theremin uses a light sensor to detect how much light is hitting it and creates a buzzing sound proportionally related to that. If you don’t understand electronics much, that’s ok, Jenny from PS:1 will explain it all and help your build your very own noisemaking theremin. (Already understand all the technical stuff? There’s a github page for the noisemaker.)
