Wall of Faces

Overview

The wall of faces will have members photos and names on it. They will light up if a member is within the space. This was started as we grew and people could not put names to faces of members. Obviously a high-tech touch has been added.

The wall will comprise of a number of boxes. Each box will have the members photo and name. The boxes will be laser cut and all fit together to build a whole wall. Each box will also contain a circuit board. This will have LED backlighting and a microcontroller (probably an ATtiny48/85). When a member is in the space (via their RFID tag) then their image will light up. Members do not swipe out, so at the end of every day then all the backlighting will reset. This will give a record of who was in the space within the last 24 hours.

This will probably be in th form of a kit which memebrs get the chance to build - including laser cut pieces and soldering the board.

Boxes

The boxes will be 60(h) x 60(l) x 30mm(w).
The design was created using BoxMaker.

Circuit

Use 6 x LEDs Transistor to control LEDs ATtiny45/85 4 way connector (male on 2 edges, female on 2 edges), so they can plug together as a grid. 4 wire: +5V , GND, CLOCK, DATA

Code

Simple code - when a command comes through (a unique identifier) then the light swicthes ON (also can send an OFF command).

Main Controller

A controller will be required to take the info from gatekeeper (which knows when an RFID tag has been read) and output a command to turn on the correct box.
