Datenklo - Wikipedia
The Datenklo (German) or data toilet (English translation) is a portable toilet cubicle which has been re-purposed to provide connectivity at hacker camps. This typically includes Wi-Fi and wired communication such as Ethernet. A major event can be served by many data toilets: for example, in 1999 the Chaos Communication Camp had 17 booths.[1]
The original Datenklo or CCC-Modem was an acoustic coupler modem in the early 1980s for which the Chaos Computer Club made plans and schematics available.[2] The moniker 'loo' refers to an ingenious idea in the construction of the device: The use of rubber cuffs, commonly available as plumbing supplies, to connect the audio transducers to a normal telephone receiver. The goal of this acoustically-coupled device was to avoid prosecution for the (illegal at the time) connection of an unlicensed device to the telephone line.[3]
The Datenklo name was subsequently repurposed to describe the use of rented portable toilet cubicles to host communications infrastructure at hacker camps:[4]
