GitHub – JanDerogee/TeleJukebox: A project based on the concepts of the Wonderfoon and Arduinofoon

Posted by jpluimers on 2021/11/18

[Wayback/Archive.is] GitHub – JanDerogee/TeleJukebox: A project based on the concepts of the Wonderfoon and Arduinofoon which simplfies the design of the Wonderfoon keeping the most important music playback feature down to

a simple PCB in a small case where you plug the phone in

The completed project works very simple:

  • Pick up the phone, you hear the “dial tone” MP3, Dial a number, you hear the MP3 0..9 playing (depending on the dialed number), When the song is over, you hear the “disconnected” MP3, You can dial another number and hear another song or hang up the phone.
  • Some phones also have a button on the front. When you press this button, the phone randomly playes one of the songe 0..9 and when that song is over, it automatically plays a new song, randomly. This will allow the person on the phone to continuously listen to the music. This may be of help to those who can’t figure out how it works but love to hear the songs over and over again.
  • You can configure the music folder from which the MP3s are played, you can use up to 10 different folders
  • You can configure the volume of the device
  • Configurations are done through the phone itself (dial 738 OR hold the button while picking up the handpiece), you hear a voice that guides you through a menu and all you need to do is dial in your settings value.

You can power this design through a USB port cable. This way the device can be fed using a simple mobilephone charger OR be connected to the PC. When connected to a PC, the TeleJukebox identifies itself like a USB-stick and you can easily modify the file without removing the card from the system. Meaning that you do no even need to open the case in order to change the collection of MP3 files. Keep in mind that when the device is in USB-stick mode, it cannot playback MP3 files meaning that in this mode it will not act like a TeleJukebox.

Music rights

Especially when using this in a professional environment. be sure the music that plays is rights free (there are music therapists for treating people with Alzheimer’s and dementia that can help you with that).

Steps, reasoning, and building instructions

A less in depth Dutch article (with 13 minute explaining video below) explaining most of the steps and all the reasoning is this multi-part one:

  1. [Wayback] .Build – Bouw een Wonderfoon – Bouw een Wonderfoon voor iemand anders – Achtergrond – Tweakers

    It works with these and younger phones as long as they can do pulse-dialing:

    De T65, W65 en T65 TDK

  2. [Wayback] .Build – Bouw een Wonderfoon – Wat is een Wonderfoon? – Achtergrond – Tweakers

    The small regular and debug boxes under the PTT/KPN phone connector box:

    .Build Wonderfoon - Twee keer TeleJukebox

  3. [Wayback] .Build – Bouw een Wonderfoon – Een goedkopere variant – Achtergrond – Tweakers
  4. [Wayback] .Build – Bouw een Wonderfoon – Slopen is zonde – Achtergrond – Tweakers

    Both boards with electronics soldered:

    The non-debug board with components to be soldered:

    .Build Wonderfoon - Onderdelen TeleJukebox

  5. [Wayback] .Build – Bouw een Wonderfoon – T65 bewerken – Achtergrond – Tweakers

    The small cleanup and modification steps (shorting the microphone) for the T65 phone:

Wonderfoon got more versatile

Note that the most recent Wonderfoon products got more versatile allowing more songs, warnings for taking pills, and ring-reminders based on morse code.
