			==2023 Phone Rebuild for Capp St==
			After some time, the 2021 reprise began to fail due to water intrusion. This resulted in the keypad entry system being taken out of service.

			The keypad was rebuilt and a RJ45 jack added within the phone case to connect the keyboard matrix to an external system.

			On the secure side of the wall, a circuit was built to read the keypad and control the strike.

			The circuit consists of protoboard with a socket for a NodeMCU, a header that a RJ45 jack is attached to (to connect to the keypad), a 5v regulator, a transistor for driving the door strike, and screw terminals for the 12v input and door strike output.

			The current design does not allow for easy use of the hang up switch or the phone receiver. It has been proposed that any projects involving these parts be kept on a separate circuit from the access control system.

	While it looks the same circa 2016, the functionality is much different. The stuff like "leave a message" and "dictate to IRC" aren't really relevant so much. Though it would be pretty cool to "dictate a message to [[Slack\|groupchat]]".		While it looks the same circa 2016, the functionality is much different.

	Another idea is to make an Intercom that allows someone to pick up the phone and speak out of the speakers in ~~marry poppins~~. "toll free nation-wide calls" is hilarious and should remain.
