Gallery of Defusable Clocks and Game Timer Pro Builds

Have you built an awesome Defusable Clock or Game Timer Pro? Send your images/videos to and tell us how you built it!

From TeamAWS in Los Angeles, California, USA

The TEAM AWS Airsoft team built a great device in a steel suitcase, which they affectionately call “The Burrito”. They modified the software to have a higher countdown value and the timer starts when the case is opened. They also amplified the sound with a speaker. Great build, guys.

Wow, there’s a lot going on in here.

They added a component that has 4 disposable flash bulbs which flash when the bomb detonates. The flashing can even be activated remotely to distract the defuser! Now that’s innovation.

Check out this video to see it in action. This was made before the flash unit was added.

The guys at Combat City are at it again. This time they’ve made a suicide bomber vest to use in their Airsoft scenarios. It looks like they’ve enclosed the clock in a plastic box for protection. Good job, and never take that vest anywhere, ever.

From Ryan in Auckland, New Zealand

The team at Judd Studio Engineering in New Zealand did a fantastic job with this clock. It’s made from a rake handle and a roll of brown paper. They ruffled up the paper a bit before feeding it into a laser printer.

Now, that is some authentic-looking dynamite. A fine effort, indeed.

From Andy in Platteville, Wisconsin, USA

Simple, but pretty nasty looking. This clock uses two 6V lantern batteries to provide 12V to the clock. A simple 2.1mm DC plug from Radio Shack made it easy to connect the batteries to the clock. Andy plans on using this for paintball scenario games. Don’t get in trouble!

From Daniel in Barcelona, Spain

This is an epic build inside a steel briefcase. A nice cover conceals the internal circuitry. Don’t take this anywhere near an airport!

Inside is a battery holder that has C4 explosive labeling on it. Nice touch.

The device is powered by six C cell batteries wired in series to provide 9V. This bomb is going to be used in an Airsoft bomb scenario, so battery power is important.

From Matt in Blaine, Minnesota, USA

Check out the Defusable Clock bolted to the side of a 50 caliber ammunition case. The liquids inside the jars are simply colored soap solution. Nice work, Matt!
