The thing, which will safely guide you through darkness. A prop used during K-SCUK 2016 night game.

NavigationThing NavigationThing

What does it do?

NavigationThing features an electronic compass and a GPS receiver, which are used for navigation of a user through a series of waypoints. Distance to the next waypoint is indicated via beeping, which adds a mysterious feeling. Closer the user is, the faster the box beeps. NavigationThing is powered by 4 AA batteries.

How to use it?

The navigation thing is ready out of box. When you power it for the first time, the unit beeps, goes black for 3 seconds and then the unit enters compass calibration mode, which is indited via purple flashing. It is necessary to rotate the unit on a flat surface until it stops flashing. After initial setup, the unit starts normal operation.

During normal operation, the thing shows either electronic compass or flashes red. Red flashing indicates missing GPS fix. The thing remembers progress in EEPROM, so user can safely remove batteries in the middle of operation and insert them back again. To reset the unit, simply short two pads in the left- bottom corner of PCB during power-up. Then restart the unit.

To change waypoints, change waypoints array in the firmware source code. When user enters a waypoint, an user supplied callback function is called.

Repository Structure

The repository is organized as follow:

  • NavigationThing contains the unit's firmware. The firmware is written in Arduino to keep things simple.

  • NavigationThingHwTest contains testing firmware, which tests the PCB - LEDs and peripherals communication.

  • hw contains schematics and PCBs in KiCAD

I am sorry, there are no CAD files for the box.
