From 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 What a fantastic build!

From 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!

From 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.

From 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.

From 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!

Nice case!

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!

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.
