This page documents the operation of Noisebridge's front gate, located at 2169 Mission Street.

{{blackbox}} '''You are standing at Noisebridge's [[Access|locked]] front gate''' through the fence around the [[Patio]] to the east.


The gate is opened using the intercom pad inside Noisebridge, next to the door to the stairs. The "DOOR" button, illustrated with a picture of a key, <strike>opens the gate</strike> seems to be broken - you may be able to use the computerised [http://pony.noise/gate "gate" method] instead.  
You see a red [[doorbell]] buzzer button, an [[RFID Token]] reader and [[Payphone]] keypad.


This switch can also be operated remotely, through an arcane and un-neccessarily convoluted system. A cable leads from the keypad through the machine shop, and up to a parallel port pair mounted on a PCB, just next to a hole in the South wall. The cable from the other side of this hole leads along the ceiling to a parallel port attached to the very top of the Wall O Tubes. This is a USB parallel port connected to [[Minotaur]].
'''EXITS:''' Opening [[Gate]] leads to [[Patio]]. Wst is [[parking]] spaces and south is [[Street]].
{{cursorboxend}}


This USB parallel port is controlled by a daemon called <tt>[https://github.com/noisebridge/gateman gateman]</tt>, which -- like all services on Minotaur -- is started automatically by [http://upstart.ubuntu.com Upstart]. <tt>gateman</tt> is called by the Noisebridge API. Minotaur also hosts the [[keycode access]] system which uses API to open the gate. Other systems including the <tt>opengate</tt> script on [[Pony]] also open the gate this way.
'''Noisebridge's front gate''' is in our parking lot on the street at [[272]] Capp St. and leads to the [[Yard]] with the regular door and roll-up garage door behind it.


So ... if you are inside the space AND reading this page via noisebridge's internal network, you can [http://pony.noise/gate JUST CLICK HERE] to invoke the above-referenced noisegate script (via the url http://pony.noise/gate ) and open that gate!
It uses the [[Payphone]] as a keypad and has an [[RFID Token]] reader for 24 hour access card holders such as [[philanthropy|philanthropists]] and [[members]].


= Usage =
* [https://discuss.noisebridge.info/t/gate-buildout-next-steps/2625 Gate Buildout Next Steps Discuss Thread]


* To open the gate from outside the space, see [[getting in]].
* To open the gate from inside the space, use the "DOOR" button on the intercom pad.
* If you are too lazy to get out of your seat and, use the <tt>opengate</tt> script on Pony.
* If you are setting up another system to open the gate, write your application to use the Noisebridge [[API]]. The API only works from within the space, so you should probably run your service on Pony. Do not try to run your system on Minotaur unless you've brought it up at a [[meeting]].

This is some ethernet cable split and used as low-voltage signal wires.


The electric latch release mechanism on the gate (called an 'electric door strike'), shown broken and jammed. To remove and repair this, unscrew the two phillips head screws and slide out the mechanism. There are also two black wires each connected to a twisted pair of cable with a wire nut that need to be disconnected to fully remove the unit.
The current wiring of the gate phone keypad, to the brains in the grey box behind, is:

You are standing at Noisebridge's locked front gate through the fence around the Patio to the east.

You see a red doorbell buzzer button, an RFID Token reader and Payphone keypad.

EXITS: Opening Gate leads to Patio. Wst is parking spaces and south is Street.

>

Noisebridge's front gate is in our parking lot on the street at 272 Capp St. and leads to the Yard with the regular door and roll-up garage door behind it.

It uses the Payphone as a keypad and has an RFID Token reader for 24 hour access card holders such as philanthropists and members.


Payphone Keypad

[edit | edit source]

This is some ethernet cable split and used as low-voltage signal wires.

The current wiring of the gate phone keypad, to the brains in the grey box behind, is:

Wire mapping
# From cable bundle To phone component
1 Gray wire row 1, pin D0
2 Green wire row 2, D1
3 Brown wire row 3, D2
4 Red wire row 4, D3
5 Orange wire column 1, D4
6 Blue wire column 2, D5
7 Blue + Black dot wire column 3, D6

From the phone, there are blue column wires and red row wires.

Added to this, the red LED and front buzzer share a signal wire pair. Green and yellow are used for these. The wp:LED has bias, a correct direction. The buzzer, phone earpiece, is driven directly by the arduino, using a tone generation library. The LED can be setup alone, and lights on each keypress, to confirm good wiring.

The last 2 white wires are reserved for future use supporting voice from the phone.
