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 Scott in Minneapolis, Minnesota, USA

Scott used a 3D printer to print something called “The F-Bomb”. If you look closely, there’s an ‘F’ on the side of the large bomb shaped 3D print. Nice!

From Max in Rome, Italy

Max and his airsoft club “Italian Tactical Troop” built this great suitcase bomb which is affectionately named “Monica”.

Indeed, Monica is very beautiful!

From Phil in San Francisco, California, USA

Phil and his daughter built this great device that looks like a pipe bomb. But this is no ordinary pipe bomb — it has a secret…

It is actually a secret compartment for storing valuables! No burgler is going to mess with this.

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.

From Dave in Orlando, Florida, USA

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!
