MakerPass

Purpose

The MakerPass project is an access control system for ingress, egress, vending, machine tools and more.

Typical Components

The following are typical components in a MakerPass installation.

Authentication Server

There is one Authentication Server per MakerPass install. The server (local or remote) runs an application instance of a common authentication protocol. Example protocols would be these

Node manager

A Node Manager communicates with multiple Wiegand Boards using RS485 (a differential serial protocol.) There is usually one Node Manager per room, or connected with as many as 32 Wiegand Boards. A Node Manager is usually an inexpensive Ethernet or WiFi-enabled embedded computer, such as a BeagleBone Black or Raspberry Pi.

Wiegand Board

There is one Wiegand Board at each access point or item (door, machine tool, vending machine). These boards provide the low-voltage control for a multitude of inputs and outputs.

These are commonly used INPUT items with a Wiegand Board:

• Wiegand card reader / pinpad
• Current sensor (to detect machine tool motor state)
• Key switch (as override for access item)

These are commonly used OUTPUT items with a Wiegand Board:

• Electric door strike
• Indicator light
• Relay
