Edison Strips and the Paper Horn

Mon, 19 Aug 2013

I've modified the experimental paper horn project so that it can play the Edison Strips I mentioned in the previous post. I've added a small piece of stiff card to the end of the read head.


Then added some side pieces to the read head to keep everything in place.


This base piece is constructed with a groove just the correct width for the Edison strip.


The base fits into place so that the Edison strip can run through the groove with the textured surface of the Edison strip touching against the stiff card end on the read head.


The Edison strip fits into place.


When the strip is pulled though at a steady speed it plays back the sound loud and clear! Click on the link below to hear how the "Merry Christmas" strip sounds. Festive greetings everyone!

    Would people be interested in

    Would people be interested in this as a download? Obviously you'd need to add your own Edison Strips from AstroMedia.de but the rest is make-able from paper.

    Let me know.

      Yes Rob, for sure! this

      Yes Rob, for sure! this design is very practical and functional!

      I think would be good if the strip was flexible enough so we could put it around two pulleys with one lever attached so we could play it continuously

      it seems to be a great project but the shipping from astromedia to the US.is a bit expensive so if your in the US or canada i found this site   that sells "talkie strips"there just like the edison strips and there $10 for each pack. but this site has tons of sayings to choose from. ory

      you can also get them from here

        Hello Rob,

        I think this is a cool addition to your sound engineering album. Also, it is a marvelous story where two technologies, developed independently of each other, came together. Also, our member Cool1983 has found a cool site.

    I can also send me the strips

    I can also send me the strips for a phonograph.
    A horn built with large membrane. But listening is a disappointment. I can not distinguish which words are heard. (Merry Christmas, happy birthday …..)
    However, it has joy prepares to Rob's suggestions to experiment with it.

    A small sample, this time to listen to” Flickr”.
