Wonderfoon is a 'old' rotary dial telephone converted into to a jukebox for elderly people with Alzhiemer disease. When a number is dialed a song from the 60's is played.
To convert the Ericson T65 telephone to a wonderfoon a small computer and mp3 player is added. To be able to build these into the phone I printed some small parts.
