“It’s hard to find someone who’d say ‘I’d love to measure radiation’ on a day-to-day basis,” says Marmeladov, but that’s exactly what he intends to convince you of. Each sensor is molded from wood and injection-molded plastic, and looks like it would fit better on the shelf of an Apple Store than in your high school’s science lab. In fact, each sensor plugs into your iPhone’s headphone jack as if it were a Square card reader.

Like Verge editor Ben Popper, Marmeladov discovered that feeling and measuring the invisible things around you can be strange and enlightening. The pack of sensors is about environmental life-logging and keeping a journal of the invisible fields you inhabit every day. Lapka is also about finding the joy in building something cool nobody has tried before. Marmeladov, dressed from head to toe in black and donning a modern mohawk, states proudly: “Our goal is to mix Yves Saint Laurent and NASA together.”
