I am loving the DIY gadget aesthetics of these FernSprecher voice-memo machines made from old telephone handsets by Karl Schatzmann of Brooklyn. FernSprecher, one of the German words for telephone, literally means “remote speaker.” One button records a message, the other plays it back. [Thanks, Karl!]

    I can’t find anywhere where it says what chip was used but one I know you can use is the HK828:

    I used one to make an ‘A Team’ music box once.

    Cool device, and probably not that much difficult to reproduce, unfortunately I can find no schematics…..
