![]() So new code was written to control the door directly from the Teensy. While this worked with the keyboard, a later problem occurred where the Raspberry Pi got damaged. This would allow code to capture the exact key pressed as follows: With this in mind Woz came up with the idea to keep all the rows low, and the columns high, then to set the column to low on keypress. The keypad uses a row and column type soldering and pinout. Jaguar donated a Teensy for this and created a new keypad that sits underneath the metal keypad. ![]() With that in place, Jaguar decided to turn the phone into a simple keyboard to replace the computer keyboard which was then outside the gate. However, the new space was in need of a door access system for the outer door, since a gate pad lock had been used for months.Ī keyboard entry system was created by Woz, in which a keyboard ran to a raspberry Pi to then activate the door strike (latch). It was decided to try add VoIP back to the phone, but after a mishap with the keyboard, the phone was set aside. It has been proposed that any projects involving these parts be kept on a separate circuit from the access control system.Ģ021 Phone Reprise for Door Entry System to New Capp St Space Īfter the move in 2020, and maybe even before? The phone had been unused. The current design does not allow for easy use of the hang up switch or the phone receiver. 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. On the secure side of the wall, a circuit was built to read the keypad and control the strike. The keypad was rebuilt and a RJ45 jack added within the phone case to connect the keyboard matrix to an external system. This resulted in the keypad entry system being taken out of service.
