Turn an old coin(quarters only) operated payphone into a doorbell/art-project for the building.
Aquired an old 'Kimus 1' aka 'PTT Sodeco TE 400'. This is an rotary-pulse-dial phone, the particular model seems to be one of the later ones and could be set to allow free calls.
The payphone will be connected to an old Fritzbox 7170 which functions as an ATA to connect to the VOIP-server. With this it can make and receive calls.
The VOIP-server will then redirect calls to spaces/renters in the building, it will only allow internal calls, or atleast no calls that cost money. 112 will be disabled to prevent prank-calls and due to reliability problems.
Coin Mechanism
This part will not be used in operation and is here only for documentation purposes.
- Validation is done mechanically by size and weight, by this mechanism:
- The coin return button will return coins from this mechanism to the user
- When validated it will move towards the coin tracking system:
- The PCB can be seen on:
and 
Cointracker PCB
Front
Back
The two IC's are an MC14007UB and a MC14584BCL, seemingly dated on 1983.
- MC14007UB: Dual Complementary Pair Plus Inverter (datasheet)
- MC14584BCL: Hex Schmitt Trigger (datasheet)
Photos
Known issues
- The ring-power from the fritzbox is rather low, due to this the bell isn't too audible.
- The lock needs to be replaced as we don't have a key for the device.
