london-based designers oscar diaz and yuri suzuki  have developed a REC & PLAY pen. first step: to draw lines of magnetic ink, then the red pen records sound and finally the black pen plays the recorded sound. designboom featured this work already in summer 2010, it now has been perfected.

to reference and indicate each pen function, the pens use the color code of cassette recorders. the REC pen is red, and the PLAY pen, black. both pens are connected to a circuit board and a power supply to feed the electronic components.

the recording head records the sound captured by the microphone situated at the top part of the pen. the black pen incorporates a speaker.

when the black pen’s head moves along the line the previously recorded sound can be heard.
