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

From Rob in Whitby, Ontario, Canada

Rob used an old electric typewriter case and added a clear plexiglass cover. A stainless steel 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!

From 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!

From 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.

From 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.

From 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.

From 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!

From Niklas in Storuman, Sweden

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.
