Capture the Box and All of Its Data!

Powered by a Raspberry Pi and Arduino, this capture the flag-style game uses GPS, LoRa, and RFID.

You’ve probably played some variation on capture the flag, where two teams try to transport an object to their territory, while at the same time avoiding getting theirs taken. The game seems ripe for a DIY enhancement, and Karel Bousson has come up with just the thing in the form of his “Capture The Box” device.

The object of this game is to take the box — an old tool case with an Arduino Mega and Dragino LoRa shield inside — and keep it in your front porch or yard for as long as possible. To claim possession of the box, RFID tags are scanned by each player and a GPS module is used to track its location. An LED matrix is implemented on the outside of the case, with its brightness optionally set by an LDR sensor.

GPS, RFID, and LDR data are passed to a Raspberry Pi over LoRa with the Things Network. This tracks who has the box at what times for scoring and acts as a server for the data so others can more easily grab it back.

It looks like a lot of fun as a neighborhood "team building" exercise, and code is found here on GitHub.
