The Justice Unlimited game used a number of electronic gadgets. This page describes those electronic gadgets and how they were designed and built.
DRUID stands for "Device for Recovery, Understanding, and Interpretation of Data." It is the primary gadget in the Justice Unlimited game.
DRUID is a wrist-mounted information device. It contains a number of features useful to teams playing in Justice Unlimited.
The Short-Range-Transmitter is a device which emits an IR (infra-red) signal which the DRUID can detect with its Short-Range-Sensors.
The Bat-Blinker is a clue which spells out messages in the air when you spin it around your head on a string.
The Resistor Clue is a circuit which is itself a clue. The solution is encoded in the componants (resistors) on the circuit board.
Here is a page describing PIC Microcontrollers which we used in several of the Justice Unlimited gadget circuits.
