I offer an aseembled device of Button Domination Timer 2.0 (DOMINATOR). It is suitable for Airsoft playground, events even large-scale events with duration up to 4 full days. Device is based on following components:

• PCB of RFID DOMINATOR 2.0
• Drilled box of RFID DOMINATOR 2.0 (2x 16 mm holes for buttons)
• Arduino Nano V3.0
• LCD 2004A with blue backlight (can swap for yellow if interested)
• 2x 16 mm button with LED backlight, red and blue
• 4x LED diodes
• 5V piezo buzzer
• 25 mm tree mounting tie-belt with auto-lock spring mechanism
• additonal parts like standoff spacer screws, M3 screws, pin headers

Buttons are clearly visible even in complete darkness, so can be used during night events without a problem and are used as user-input for occupying the DOMINATOR point.
The occupation starts counting the total time of the occupation of the point for the given team (i.e. the time continues from the moment where the last total time ended).

The point is occupied by holding the button for 5 seconds continuously. If the hold is interrupted, the player must hold it again for 5 seconds. The progress of the occupation is also dynamically shown on the display by a bar. If the DOMINATOR has already been occupied by another team, holding the button for at least 50% of time will neutralize the point, meaning the original team is no longer active on the point and there is no more time counting for that team even if the occupation is interrupted (between 51 and 99%). Buzzer signals the successful occupation fo the point, when archived. The active team is also indicated by a separate LED diode for the given team in the right part of the DOMINATOR.

Within the hardware, I will deliver also a BOM file and firmware in .hex format, which will be uploaded in the device also. I do not supply the source code .ino. You can clone DOMINATOR to any number of your own devices. I can also sell GERBER files for PCB production or .STL file for 3D printing the box (ask for the price).

DOMINATOR's timer has a second resolution in which it counts and can visualize up to 99 hours, 59 minutes, 59 seconds. It can therefore also be used for several-day events such as LARP, MilSim. The referee can neutralize the point by pressing both buttons simultaneously. If both buttons are held down for an additional 5 seconds, the time counters for the blue and red teams will be reset - erasing process.
 

I can include the name of your team or the area where it will be operated in the firmware. I can also set a 3-letter team name if you do not want to use BLU for the blue team and RED for the red team.

Box dimensions 124x123x48 mm, weight 300 grams. DOMINATOR can be mounted on a tree, pipe through a strap with a spring mechanism. DOMINATOR should be placed at eye level for a good viewing angle.

DOMINATOR has an accessible contrast potentiometer from the back (necessary to change to summer and winter mode). It has modular design that allow you to replace all main components and buttons without needing to solder anything. You can just unplug the component and plug in the new one. DOMINATOR is powered via a USB miniUSB cable (not supplied). Consumption 70 mAh. Suitable for power supply from a power bank. You can power it up also using 9V power supply such as Lipo batteries (necessary to solder the connector and cables). By changing the wiring, you can also achieve different behavior of the button's LED backlight, where it can light up or go out when pressed, etc. It's up to you.

Post fees are not included within the price
