Alarm clock grenade

Alarm clocks and methods of their use on Habrahabr have been discussed more than once. The overall concept of alarms and wake. Runaway alarm clock . Alarm clock in the form of a pillow , etc. And here's another fun thing. For aggressive dormice. Grenade Alarm Clock .



The idea is not new. A grenade for awakening could be bought back in 2005. But progress does not stand still (and indicated by reference, and not the alarm as a whole, but a cracker), and the grenades are no longer of that system. In this, at least, there is a display. The display, the PVC case and the sensor, which is triggered by a shock and turns off the alarm. Blow to produce preferably on the wall. On the case of "grenades" for particularly dull and so it is written: off the wall.

The fact that when you throw a "grenade" does not damage the body - is understandable. But what will happen to the display after a couple of awakenings ... Suddenly, the angle will shake. After all, breaking $ 23 against the wall is, of course, a pleasure. But the alarm should work, and not to roll broken in the garbage can.
