RFID DOMINATOR: The Ultimate Domination Stopwatch for Airsoft, Paintball
About RFID DOMINATOR – Airsoft Stopwatch
RFID DOMINATOR is a stopwatch created for Airsoft, Paintball, which increases the game experience and brings fairness. They are suitable for the DOMINATOR, Capture the Point game mode. DOMINATOR creates a point that is occupied by a team player. The device includes an LCD character display that informs about the current time of each team. At the same time, an LED diode signals the active team on the point. The player occupies the DOMINATOR point by attaching an RFID bracelet or card. When the point is occupied, an alarm beeps, announcing a change on the point. The team's time is counted until a player from another team attaches their RFID tag, or until the time is stopped by the referee. Time continues to count after the point is occupied. DOMINATOR counts the total time occupied by all teams in the game. Can be used for 2 or 4 teams in one game. In addition to stopping the clock, the referee may also reset it before a new game.
Usage Scenarios
Ideal for playgrounds, fields offering Airsoft / Paintball experience. Events such as LARP, MilSim, Scenario, Speedball, due the flash size that supports hundrets of RFID tags in a single application

Frequently Asked Questions
Below are the most frequently asked questions from our community.
What Is the Energy Consumption of the System?
The system typically consumes 40–60 mAh @ 5V, equivalent to 0.2–0.3 W. A 2000 mAh power source can run the system for 30–35 hours, depending on the load.
Can I Power It via Powerbank?
Yes, the RFID DOMINATOR can be powered directly using a powerbank through its 5V output. RFID DOMINATOR requires MiniUSB connector, there can be some versions of Arduino Nano with microUSB connector aswell.
How Can I Upload the Firmware?
Whether it’s DEMO or FINAL firmware, use the provided .hex file compatible with Arduino. Upload it using the XLoader tool. For Arduino Nano with the Old Bootloader, set the speed to 57600 baud/s, for the New Bootloader, use 115200 baud/s. Successful upload is confirmed by a message from XLoader, it can inform you about unsuccessful upload process.
How to Copy Existing Firmware?
Simply upload the same firmware file (.hex) you have received via email to your next RFID DOMINATOR unit. It will work by the same way and will react to the same RFID wristbands and cards. There’s no limit to the number of clones you can create, it's up to you.
Can be a team name changed?
Not at the moment, but soon it will be possible, when AT commands extension will be finished. Team names need to have maximum 3 letters (it will be limited by the software).
Can DOMINATOR be used outdoors?
DOMINATOR does not have a waterproof case. If it is dry, it can also be used outdoors. Mainly used indoors or under a shelter.
In what form is DOMINATOR available?
DOMINATOR is available as firmware (worldwide) or as a physical device in the form of a DIY kit (Europe only) that you can assemble yourself. You can also create your own program if you do not want a custom RFID DOMINATOR program implementation.
