Hierbei handelt es sich um einen Uhrenbausatz von nootropic design mit einem lustigen Extra:
Die Uhr besitzt eine Countdownfunktion, nach dem drücken des Start Buttons läuft ein 10 Sekunken Countdown los und man muss in dieser Zeit den richtigen Draht (4 Stück sind vorhanden) zum entschärfen der Uhr kappen.
Nach dem Neustart des Countdown wird automatisch ein neues "neuer" Draht zum entschärfen der Uhr führen, diese wird per Zufallsgenerator ausgewählt.

The Defusable Clock 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! Available as a kit (soldering required) or as an assembled/tested unit in limited quantities.

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.

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.

Dear Federal Agents and other Law Enforcement:

This is only a clock. It is no more dangerous than any other clock. I don't know anything about explosives beyond what I've seen in movies. So, if you are with the FBI, Department of Homeland Security, CIA, ATF, Department of Defense, National Counterterrorism Center, Interpol, or SEAL Team Six, please know that I am on your side!
So, we're cool, right?

By using your imagination, you can build a clock that looks like a dangerous device. For example, phony dynamite can be made by wrapping brown paper around wood dowels. More project ideas are in the defusable clock gallery and you are invited to send in your own pictures.

Dear Pranksters:

Yeah, you. I know you are excited to scare your friends and coworkers with a phony bomb, but use your head. This kind of device can make people freak out and call the authorities. So don't bring this to school or to work, and certainly don't bring it anywhere near an airport! Seriously, don't get yourself into trouble.

Clock Features

Functions as an ordinary alarm clock with snooze alarm and two alarm modes (normal beeping, and countdown sequence).

There's no battery backup, but the current time is always preserved in non-volatile EEPROM memory, so you don't have to reset the time after a brief power interruption or if you move the clock from one place to another. Alarm time and mode are also preserved in EEPROM.

When you press the big red button, the detonation countdown sequence starts. You've got 10 seconds to cut the correct wire or the clock "explodes" with flashing red LEDs. (You can set the countdown sequence to higher values -- see detailed usage below.)

The wires are held with screw terminals so they are easily replaced. If you don't want to actually cut the wires, you can leave the screws a bit loose and pull the wires out instead.

Requires a common 9V DC power adapter with a 2.1mm center-positive plug. The adapter should be rated for at least 200mA. This is also available in the nootropic design store.

The clock can also be powered by batteries. Six AA, C or D cell batteries can be used to provide 9V. C or D cells will provide the longest life. The clock draws about 90mA of current.

The Defusable Clock is completely hackable. It is powered by an ATmega328 microcontroller with the Arduino bootloader, so you can easily reprogram it to your liking. The software is all open source!

Usage Guide

Setting the Time

To set the time, simply press the HOUR and MIN buttons. You can hold the buttons to make the numbers advance automatically. When setting the hour, the LED marked PM will indicate that the hour is PM. (The PM LED is only lit when setting the time and alarm because it is quite bright and distracting.)

Setting the Alarm

Hold down the ALARM button (lower left corner of board), then use the HOUR and MIN buttons to set the alarm time. The LED marked PM indicates if the alarm time is PM.

There are 3 alarm modes, OFF, ON, and DEFUSE. To cycle through the alarm modes, hold the ALARM button, then press the large red DET button. Two LEDs indicate which mode the alarm is in. One LED is near the ALARM button, the other is near the large red DET button.

LED indicatorsalarm behavior
alarm OFFalarm LED off, DET LED offalarm is off
alarm ON (normal mode)alarm LED on, DET LED offalarm will beep
alarm ON (defuse mode)alarm LED on, DET LED onalarm will beep a few times, then 10 second countdown sequence begins

Turning off the Ringing Alarm

When the alarm is beeping (normal mode), turn the alarm off by pressing the alarm button.

For snooze, press the red DET button. Alarm will ring again in 9 minutes.

If you are using the "defuse" alarm mode, you can try to defuse the clock by cutting the right wire. Otherwise, the 10 second countdown will reach 0 and the device will "detonate".

Starting the Countdown Sequence

Press the red DET button to start a 10 second countdown sequence. If you want the countdown length to be longer, press the HOUR and MIN buttons before releasing the DET button. You can set the countdown to be up to 99 minutes and 59 seconds.

During the countdown, choose the correct wire to defuse the device. One wire stops the countdown safely, two have no effect, and one will cause the device to detonate immediately. The role of each wire is assigned randomly each time the DET button is pressed.
