The latest alarm clock

The alarm inventor is an Indian teenager named Sankalp Sinha. In order to prevent the alarm button from pressing the alarm button, he tried to set the electric shock device on the alarm button. Compared with Pikachu of 100,000 volts, this alarm clock is simply weak. The shock it released will only make your fingers slightly numb.SANKALP hopes that this alarm clock named "Good morning, singing and electric shock" can make more people use it in daily life as soon as possible. He said that he used this alarm clock and was no longer afraid of sleeping too much. Because according to his own experience, people can really wake up only after being shocked. He has made a prototype and is committed to studying the alarm clock that can adjust the voltage, and can enter production shortly after negotiating with the manufacturer.

Quartz alarm clock

The quartz alarm clock can also be called "crystal vibration electronic meter" because it uses the "hair vibration phenomenon" of the chip. When the crystal receives an external force voltage, it will have the properties of deformation and telescopic. On the contrary, if the crystals are compressed, the ends of the crystal will generate electricity; this kind of nature can also be seen on many crystals, which is called "voltage electricity. Effect". The quartz watch is the crystal that uses cyclical continuous "hair vibrations" to bring us accurate time.First of all, if the chip in the quartz table is powered, the crystal will be vibrated correctly with the number of weeks of 32768 Hertz; and then the number of signal current weeks of the signal current of 1Hz (one -second change between the current) must be turned into 1Hz. Add the amplitude of some signals (the current generated due to vibration is weak), followed by some signal current to launch the rotor gear, the second hand on th
