Hacking old telephones for a new exhibition

I have taken the job to hack old telephones that are going to be part of a new exhibition at Borgarsyssel Museum. I am modifying the phones adding a Adafruit 2133, Sound FX Audio Processor Application Board so I can have a audio file playing when a visitor picks up the phone.

In total, there will be ten telephones for the public to choose from. I will do a few follow up posts about the progress.
