Great project that is ‘saving’ sounds from the past.

»Conserve the sound« is an online museum for vanishing and endangered sounds. The sound of a dial telephone, a walkman, a analog typewriter, a pay phone, a 56k modem, a nuclear power plant or even a cell phone keypad are partially already gone or are about to disappear from our daily life.

Just take a look at this flying sensor board.
Great fun and very DIY.
