In the Maker Shed: Poulsen’s Wire Recoder Kit

Poulsen’s Wire Recoder Kit, from the Maker Shed, uses wire and magnetism to record sound. Danish engineer Valdemar Poulsen discovered that it was possible to record electrical signals in magnetic material and invented the magnetic wire recorder (telegraphone) in 1898. This simple yet fascinating kit lets you explore this phenomenon not just on wire but anything magnetic! Save your voice on scissors, chairs, or even an escalator!

Earlier this summer, Brett was working on a nifty 3 LED and 2 AAA battery holder design at the Boston Area Makerbot meetup. We get together when enough people feel the need, generally at Sprout in Somerville. When we got together again this week, he was able to happily report on the project and the role his making played in the big day.

The initial plan was to use throwies, but I felt they wouldn’t give as much light as a commercial 3 LED solution. This led me to a fun, albeit time consuming project.
