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 Chris in Houston, Texas, USA

Chris did his research to create a very authentic dynamite label. He used 3/4″ PVC pipe because the outer diameter of the pipe is about 1″. Very nice.

From Lorenzo in Genova, Italy

This device is used in weekend airsoft games by the Corsari ASG Team in Genova, Italy. But during the week, it serves as Lorenzo’s bedside alarm clock!

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.
