Afternoon,

I'm currently working on building a 3 digit step by step PBX switch and I will most likely be documenting it here as well as my defcon.social! I will upload progress updates/photos soon! The initial design is going to be 2 Line Finders, 2 selectors and 2 Connectors to have at least 2 calls up at once! (I have 3 of each switch type for spare parts)
