What's inside, how it works?


Stopwatch that works similar to chess clock, it can count time for only one team at the moment. It is equipped with RFID reader that is able to read RFID cards and wristbands of players. Domination Timer is operated by 8-bit microcontroller AVR ATmega. LCD character display is used for displaying 2 up to 4 teams total occupying time. Player is able to occupy point by attaching his RFID wristband to RFID reader. Time starts to count, beep will annouce change on the Domination Timer point. Onboard LEDs are showing actual color of active team, piezo buzzer inform about event of RFID card attached to the RFID reader. Everything is soldered on custom PCB that exists in two version depends on 2 or 4 teams firmware support. PCB supports hotswapping of the main components without need to solder anything. Suitable for up to 4-day non-stop operation (MilSim, LARP compatible) with power consumption around 60 mAh. If team is active on the point, time is counting, until there will be attached wristband of other team's player, or when Referee attach his pause card, or Eraser can pause and reset time using his card.

Advantages of the system


Sport friendly

Can be used for Airsoft, Paintball, Nerf wars or similar sport. Possible to implement more than 100 RFID tags per each entity.

Scalable

Easily scalable for 1, 2, 3 or 4 teams per game with two custom PCBs. User can clone firmware to multiple devices to make more props around playground that reacts on the same RFID tags.
