Hack In The Badge

Description

Some information for orienting on a badge for the anual Hack In The Box event. The goal:

• a battery powered badge
• RGB led
• Some radio comms (transcieve)
• AES ecnryption

Minions

The badge can communicate with some kind of node. The goal is that everyone has it's own badge that changes color if some action is wanted. Like Return to HQ, Go to toilet or whatever useful you can come up with. By receiving those duty messages the RGB LED turns a different color. The user can reset it's badge with 2 buttons.

1. is I'm already busy.
2. is I'm done with the task you gave me.

Officers version

Officers can make messages from a menu, their badge has a little screen with a menu in it. They can select a duty message to specific person/badge, or collect a minion who is standing idle.

Technical

Here some idea's of the hardware components. An Arduino is easy to program and later on useable in other projects. The communication part needs to be low power and have an acceptable range indoors.

The board consists of:

• some kind of programmable chip
  • Arduino
  • ARM
• Radio chip
  • bluetooth 4.0
  • Wifi
  • 433 MHz
  • 868 Mhz
  • Xbee

main board

An arduino 328 is small and capable enough to fulfill this project, it's easy to program with the Arduino IDE. There are enough open hardware projects available to give a big headstart.
To name a couple :

• Moteino.
