Have you built an awesome Defusable Clock? Send your images to email@example.com and tell us how you built it!
This clock was made by covering 7 wooden dowels with brown paper. The dowels are 1 inch (2.5cm) in diameter, and 9 inches (23cm) long The paper is from a paper lunch sack. The dowels are held together with black electrical tape.Wood dowels are cheap and readily available at home improvement stores like Home Depot or Lowe's.
This clock was made to look like C4 plastic explosives. It's really just gray modeling clay.
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.

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!

Tucker did a fine job building this dynamite Defusable Clock, and did an even better job photographing it. Can you tell that Tucker is a photography student specializing in product advertising?
The guys at Combat City, an Airsoft battlefield, put together this freaky-looking device. "Use Caution" -- no kidding!

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.

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.

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.

This looks scary even when the suitcase is closed!
This looks like a very powerful device. Very rugged. The luggage inspectors at the airport would not be pleased...
Contributed by 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.

Max and his airsoft club "Italian Tactical Troop" built this great suitcase bomb which is affectionately named "Monica".
Indeed, Monica is very beautiful!
Contributed by 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!
Contributed by Chuck and Scott in Los Angeles, California, USA
Chuck and Scott are experienced prop builders in Southern California and have built this amazing bomb. According to them, the "bomb" must be kept at very low temperatures or it will realease a highly toxic gas into the air! They have a great video here!

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!
Contributed by Todd in Winnipeg, Canada
I like the FAT yellow wire leading to the detonator. Todd made a printable template that anyone can use to print the DYNAMITE stencil on brown paper. Thanks, Todd!
Contributed by Urs in Munich, Germany
Simple, but nice. Notice the skull and crossbones symbol on the dynamite.
Contributed by Kip in Las Vegas, Nevada, USA
This package would certainly be a surprise to anyone! Nice work, Kip, and don't send this crate to anyone.
Contributed by 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.
Contributed by Paul in Brooksville, Florida, USA
This one has two detonators, one at each end!
Contributed by Andrey in Kirzhach, Russian Federation
Andrey and his airsoft team "Whiteberry" did an amazing job with this build. Notice the customized ABS enclosure. The display is protected with 3M LCD protective glass. They also added a dynamic speaker for high volume. Don't forget to watch the video below!
You won't believe this video. I watched it over and over! Watch it in full-screen mode. The titles are in Russian, but I don't care -- it's simply awesome!
Contributed by Fabiano in Verona, Italy
This contribution comes from the Airsoft team GHOST SOFTAIR VERONA. They used 7 paper cylinders 33cm long and 4cm in diameter. Nice job guys.
The cylinders are closed at the ends with plastic plugs. The center cylinder holds a 9.6V 1600mAH NiCd battery to power the clock.
Contributed by Mark in Colorado Springs, Colorado, USA
This picture really tells a story. Mark and his kids built this as a Christmas present for his brother in the 82nd Airborne Division of the U.S. Army. The plastique is made of modeling clay wrapped in clear tape, and the blasting caps are wire connectors. In case you are wondering, that's a real AK-47 in the background. Thanks a million, Mark.

This is a pretty classy-looking bomb in a nice cigar box. Jason wanted to make somemething that looks like a biological threat -- I'd say he succeeded!
Contributed by Dave (a.k.a. "Jake Blues") in Wellington, Ohio, USA
Dave (or should I say "Jake Blues") created this menacing scene with a wine bottle box, wood dowels with a photoshopped dynamite label, and some copper plumbing caps. And why not include a pistol for a more dramatic effect?
Contributed by Gamepod Combat Zone in Antioch, California, USA
This Airsoft facility (the largest in the world at 120,000 square feet!) uses this device to delight their customers. They added a 13-pin keypad to activate a relay that powers up the "bio weapons canisters". The even made a second board with a relay that controls a 130 dB siren. Great job!
Contributed by Edward and Conrad in Columbia, Missouri, USA
These guys from Regulators AirSoft built this prop to use in an arena in Springfield, MO. I wonder what's inside this nice looking case...
The canister is made with red transparent .12 gram BB's with two dozen strip red LED lights used for R/C Airplane night flying. Mock C-4 is made of clay. Power comes from a CPU power supply with a 11.1V Lipo battery. Blasting charges are made from .223 shells. Each switch has a function: power to cooling fan, power to canister, and power to all lights. The light around the power box is from a landing light kit from nitroplanes.com. What a fantastic build!

Action Events Sweden created a great prop for their Airsoft events. There are 4 wires that the participants can cut to try to defuse the bomb. The Defusable Clock circuit is expertly installed underneath a panel with the display showing through a cutout.
Contributed by Matt in Atlanta, Georgia, USA
Matt built this great device as a surprise birthday gift for his wife who is a big fan of the TV show NCIS. At the end of a treasure hunt, she had to defuse this device! It is made from PVC pipe wrapped in custom labels printed on red paper. Great job, Matt, and what a thoughtful gift!
Contributed by David in Mountain View, California, USA
David and his 9 year old daughter built this wonderful device from old wine keeper nitrogen tanks and old plumbing supplies. His daughter did all the soldering herself (nice job!). This is definitely one of my favorite contributions, and gets extra points for originality.

Tim has a new bedside clock to wake him up in the morning. WAKE UP, TIM!
Contributed by Rick in Dunbarton, New Hampshire, USA
Rick built a classic C4 plastic explosive device using plasticine clay. Notice the mercury tilt switch from an old thermostat on the top of the device. It is connected to the detonation button, so if you don't handle this carefully, you will start the countdown sequence automatically! Besides, the mercury switch makes it look cool.
Contributed by Neil in Hoddesdon, UK
Neil with Fenland Airsoft in England made this great MILSIM prop. He added lots of hardware like two key-switches, a motion sensor, and a relay-driven siren that will make your ears bleed. His device has special software that causes the countdown to speed up when the wrong wire is disconnected! For all the details, watch his extremely comprehensive video.
Contributed by Mike in Tijeras, New Mexico, USA
Mike built this excellent movie prop for a film of some sort, and I think it looks great. The studio owner he was working with liked it so much that he offered to buy it!
Contributed by Hercules in Staten Island, New York, USA
Hercules (yes, that's his real name) runs a big airsoft and paintball facility. He's really taking these devices to new levels.
Super scary looking...
Nice build in a very professional looking case!
Contributed by Brian in Cary, North Carolina, USA
Brian built a classic dyamite unit that he will put to good use...somehow.
Contributed by Rob in Whitby, Ontario, Canada
Rob used an old electric typewriter case and added a clear plexiglass cover. A stainless steele thermos makes a very convincing explosive container.
Rob is using this device in an "escape room" game where the competitors must solve a series of puzzles, ultimately needing to unlock this case and cut the correct wire to defuse the bomb!
