NOTICE: This product is our classic kit that you assemble. If you want fully assembled electronics, please see the new Game Timer Pro.

The Defusable Clock kit is an electronics kit that lets you build a scary looking clock that you can actually “defuse”. Only the electronics are included — you use your imagination to build the device you want! You can get ideas from the gallery of defusable clocks.

The Defusable Clock is a fully-functional alarm clock just like you’d expect (a normal beeping alarm, snooze alarm, etc.). But at any time you can press the big red button to start a scary countdown sequence exactly like bombs in Hollywood movies.

There are 4 wires across the top of the clock. You have 10 seconds to choose the correct wire to cut: one wire stops the countdown and saves the day, two have no effect, and one will “detonate” the device immediately. These role of each wire is randomly assigned when the detonate button is pressed, so it’s a new challenge every time. You can increase/decrease the countdown time if you want.

Also, the wires are attached with screw terminals, so you can replace them easily. If you don’t want to actually cut the wires, you can just pull them out of the screw terminals if you keep the screws a little loose. Extra wires are available in our store.

Soldering is required to assemble. You can learn to solder, and this kit can be your first project. All components are through-hole; there are no surface mount parts. There are many soldering tutorials: here is a good one.

Requires 9V power source with 2.1mm center-positive plug (not included):
9V DC wall adapter (recommended for long term operation)
AA battery holder with plug (short term, portable operation)
