So, you have a vintage phone and you want to hack it back! Ok, here is how to do it.

1. Get all the parts you need to build your Vintagephone, the parts are listed here.
2. Open the case of the vintage phone, you should easily find the screws.
3. Disconnect the cables from the central board and find the cables that go to the handset.
4. Using a breadboard experiment the configuration Wemos + Mp3 player + handset as described in this log.
5. Add new parts to your breadboard project! Find the cables and connect the rotary encoder to the Wemos and try to read the dialed number as described in this log.
6. Now connect the handset switch, you have to find the correct pins with a tester. You have to connect also the bells to the Wemos, this steps are detailed in this project log.
7. Now that you have all the parts connected you can upload all the software:
   1. Download mp3 files from the Github projects and store them in the micro sd. If you want to use different clips you can create them with free text to speech at Murf.ai
   2. Download Vintagephone and data for the SPIFFS to your Arduino projects folder and upload both to the Wemos
8. Test the project on the breadboard, with the vintage phone case opened and parts connected. Dial 23 to ativate access point and configure wifi access! Try to call 1. 
9. Move the project from the breadboard to perfboards. I've uesed two small 4x6cm perfboards, maybe you can do it better. All the parts must stay inside the case! Can you design a PCB to assemby it better?
10. Close the case.
11. Read the log about the Arduino software. And try to make your custom services!
