Fortunately, Ruggie takes the ease and convenience out of simply rolling over and slapping “snooze.” With Ruggie, you must apply pressure to a plush mat for three seconds to stop the alarm. The alarm can be set to 120 decibels, too, to further annoy you out of bed. For sake of perspective, 120 decibels is on par with the noise level of a chainsaw. Pleasant.

A wall clock is not only a household necessity, but can also be a stylish home accent piece. Features like analog roman numerals or digital displays can reflect a classic or high-tech style, an oversized silver metal clock can turn a wall into a decor feature, and a beautiful and ornate antique piece can lend a stately touch. Available in a wide variety of other designs and themes, choosing a wall clock to complement your decor can be easy and fun.

The timekeeping part of all weight-driven clocks, including large tower clocks, is substantially the same. The figure shows the mechanism of a simple weight-driven timepiece with a pendulum. The frame is made up of two plates that carry the pivots of the various wheels and other moving parts and that are united and spaced by four pillars. The driving weight hangs from a line coiled around a barrel or sprocket, which is raised by turning the winding square or, in some cases, by pulling on the line. The main wheel engages with the centre pinion, on the arbor (axle) of which is also mounted the centre wheel. The front pivot of this wheel and pinion is lengthened to the right of the illustration; it carries the minute hand and part of the gearing necessary to drive the hour hand.

Analog clocks display time with an analog clock face, which consists of a round dial with the numbers 1 through 12, the hours in the day, around the outside. The hours are indicated with an hour hand, which makes two revolutions in a day, while the minutes are indicated by a minute hand, which makes one revolution per hour. In mechanical clocks a gear train drives the hands; in electronic clocks the circuit produces pulses every second which drive a stepper motor and gear train, which move the hands.

By the time that phone hits the nightstand, you've lost precious sleep time, you've tricked your brain into thinking it's wake-up time instead of dream time, because the glow of the blue light emitted by your phone reduces your body's release of melatonin, the hormone that regulates your sleep cycle. Instead of relaxing, you've stimulated your mind. All of that adds up to poor quality sleep followed by a groggy, foggy, "I don't know why I'm so tired," kind of morning.

Greek astronomer Andronicus of Cyrrhus supervised the construction of the Tower of the Winds in Athens in the 1st century B.C.[11] The Greek and Roman civilizations are credited for initially advancing water clock design to include complex gearing, which was connected to fanciful automata and also resulted in improved accuracy. These advances were passed on through Byzantium and Islamic times, eventually making their way back to Europe. Independently, the Chinese developed their own advanced water clocks(水鐘)in 725 A.D., passing their ideas on to Korea and Japan.
Although the mechanisms they use vary, all oscillating clocks, mechanical, digital and atomic, work similarly and can be divided into analogous parts.[64][65][66] They consist of an object that repeats the same motion over and over again, an oscillator, with a precisely constant time interval between each repetition, or 'beat'. Attached to the oscillator is a controller device, which sustains the oscillator's motion by replacing the energy it loses to friction, and converts its oscillations into a series of pulses. The pulses are then counted by some type of counter, and the number of counts is converted into convenient units, usually seconds, minutes, hours, etc. Finally some kind of indicator displays the result in human readable form.

As of the 2010s, atomic clocks are the most accurate clocks in existence. They are considerably more accurate than quartz clocks as they can be accurate to within a few seconds over thousands of years.[54] Atomic clocks were first theorized by Lord Kelvin in 1879.[55] In the 1930s the development of Magnetic resonance created practical method for doing this.[56] A prototype ammonia maser device was built in 1949 at the U.S. National Bureau of Standards (NBS, now NIST). Although it was less accurate than existing quartz clocks, it served to demonstrate the concept.[57][58][59] The first accurate atomic clock, a caesium standard based on a certain transition of the caesium-133 atom, was built by Louis Essen in 1955 at the National Physical Laboratory in the UK.[60] Calibration of the caesium standard atomic clock was carried out by the use of the astronomical time scale ephemeris time (ET).[61] As of 2013, the most stable atomic clocks are ytterbium clocks, which are stable to within less than two parts in 1 quintillion (2×10−18).[62]


Sony always makes good products, and this little cube packs a powerful alarm in its punch.

You get a backup battery just in case the power fails you during a storm, but you also get ten programmable radio station buttons.
About 1581 Galileo noticed the characteristic timekeeping property of the pendulum. The Dutch astronomer and physicist Christiaan Huygens was responsible for the practical application of the pendulum as a time controller in clocks from 1656 onward. Huygens’s invention brought about a great increase in the importance and extent of clock making. Clocks, weight-driven and with short pendulums, were encased in wood and made to hang on the wall, but these new eight-day wall clocks had very heavy weights, and many fell off weak plaster walls and were destroyed. The next step was to extend the case to the floor, and the grandfather clock was born. In 1670 the long, or seconds, pendulum was introduced by English clock makers with the anchor escapement.

Slave clocks, used in large institutions and schools from the 1860s to the 1970s, kept time with a pendulum, but were wired to a master clock in the building, and periodically received a signal to synchronize them with the master, often on the hour.[71] Later versions without pendulums were triggered by a pulse from the master clock and certain sequences used to force rapid synchronization following a power failure.

In a master clock system, electricity is used to give direct impulses to the pendulum, which in turn causes the clock’s gear train to move, or to lift a lever after it has imparted an impulse to the pendulum. In various modern master clocks the pendulum operates a light count wheel that turns through the pitch of one tooth every double swing and is arranged to release a lever every half minute. This lever gives an impulse to the pendulum and is then restored to its original position by an electromagnet. The pulse of current that operates the electromagnet can also be transmitted to a series of distant dials, or slave clocks, advancing the hands of each through the space of a half minute. Thus, a master clock can control scores of dials in a large group of buildings, as well as such other apparatus as time recorders and sirens.

“Great little dual alarm clock. Super easy to set the two alarms. Easy to use. It has a night light feature with adjustable dimmer, which is great. You can adjust the display completely dark so you don’t see the numbers. Then you can just hit the snooze button when the alarm is not ringing and the display lights up. It’s powered only by 3 AA batteries: no electric cord, no USB, nothing that you need. If you need a fancy alarm clock that sprays water in your face, this is not it.”
