Game Timer Pro
JUST ELECTRONICS -- NO PHONY BOMB PARTS INCLUDED!
The Game Timer Pro lets you build a scary looking timer or clock that you can actually "defuse". Nootropic completely redesigned their famous Defusable Clock product to be perfect for airsoft competion, escape rooms, games, film props, or other professional activities. Only the electronics are included -- you use your imagination to build the device you want. Completely assembled -- no soldering required.
When the big red button is pressed, the countdown sequence begins, exactly like bombs in Hollywood movies. There are 4 wires across the top of the clock. You have to choose the correct wire to cut before the countdown reaches zero. You have complete control over which wire defuses it and which wire causes immediate detonation. You can even assign a wire to speed up the countdown or to pause it for a few seconds. The Game Timer Pro gives you control of many configuration options, all described in Nootropics instruction manual and video tutorials.
Fully configurable with an easy to use menu system. Everything is documented in the excellent instruction manual and videos. All configuration changes are also preserved in EEPROM when power is disconnected.
Requires a common 9V DC power adapter with a 2.1mm center-positive plug, or you can power it with 6 AA batteries and a battery holder. You can also connect power to the pads marked + and -. This is useful if you have a 7.4V or 11.1V LiPo battery.
The wires are held with screw terminals so they are easily replaced. If you don't want to actually cut the wires, you can leave the screws a bit loose and pull the wires out instead.
You can connect a keypad that requires your players to enter a 4 digit code to defuse.
Relay trigger connections for both detonation and defuse sequences, allowing you to activate external relays for easy control of a siren, smoke grenade, or whatever. You can even set the duration of the relay activation in the configuration menu. IMPORTANT: The trigger pins can only deliver 20mA of current, so do NOT try to directly control a device that requires lots of current.
Do you like coding? The Game Timer Pro is completely hackable. It is powered by an ATmega328 microcontroller with the Arduino bootloader, so you can easily reprogram it to your liking. This requires a USB to serial adapter. The software is all open source and available on GitHub.
