| Description | A DIY field telephone kit |
| Author(s) | Paul, Phil, Severin |
The Chaosvermittlung is a group of people that builds up a field telephone network at hacker conferences and camps. One idea that came up during the GRODEN'18 was to build our own field telephone. Let's do it!
Ideas
- Use an old regular telephone as a base, build a PCB that replaces the old internals
- Build a telephone from scratch, laser cut case, etc.
Open Questions
- Do we need a transformer? Or can that be replaced?
- If not, what kind? How to get it easily and cheaply?
- Do we need the ringing voltage generator? Or can we replace that?
