Auditory and projection clocks can be used by people who are blind or have limited vision. There are also clocks for the blind that have displays that can be read by using the sense of touch. Some of these are similar to normal analog displays, but are constructed so the hands can be felt without damaging them. Another type is essentially digital, and uses devices that use a code such as Braille to show the digits so that they can be felt with the fingertips.
Set up your bedroom clock to be close enough to you to shut it off, but far enough away that you have to get up to actually his snooze or power it down. Your digital alarm clock should also be a radio alarm clock, so you can wake up to some tunes and start the day off right. Alarm clocks for heavy sleepers are going to have a louder radio capability, which will get through those thick dreams of yours, and get you up.
The first precise timekeeping mechanism, whose principles of motion were discovered by Galileo, was the simple pendulum (see below). The accuracy of modern timekeeping has been improved dramatically by the introduction of tiny quartz crystals, whose harmonic oscillations generate electrical signals that may be incorporated into miniaturized circuits…
The tick duration must be positive. If it has a part smaller than a whole millisecond, then the whole duration must divide into one second without leaving a remainder. All normal tick durations will match these criteria, including any multiple of hours, minutes, seconds and milliseconds, and sensible nanosecond durations, such as 20ns, 250,000ns and 500,000ns.

A water-powered cogwheel clock was created in China in AD 725 by Yi Xing and Liang Lingzan. This is not considered an escapement mechanism clock as it was unidirectional, the Song dynasty polymath and genius Su Song (1020–1101) incorporated it into his monumental innovation of the astronomical clock-tower of Kaifeng in 1088.[19][page needed] His astronomical clock and rotating armillary sphere still relied on the use of either flowing water during the spring, summer, autumn seasons and liquid mercury during the freezing temperature of winter (i.e. hydraulics). A mercury clock, described in the Libros del saber, a Spanish work from 1277 consisting of translations and paraphrases of Arabic works, is sometimes quoted as evidence for Muslim knowledge of a mechanical clock. A mercury-powered cogwheel clock was created by Ibn Khalaf al-Muradi[20][21]
“The alarm is loud with a lower frequency melody which I like since I have high-frequency hearing loss. Guaranteed to wake anyone up when the alarm goes off which is super important to me, especially if I’m using the alarm clock to wake up to catch a flight. … When the alarm goes off, press the large snooze bar on the top to have the alarm go off again in five minutes. Pressing the snooze bar on top at anytime also lights up the numbers and bars on the clock’s face, but the hands are a bit hard to see in the dark since the hands don’t light up. When the alarm on/off switch is turned to the off position, there’s a cute voice that says ‘Good Morning!’ which brings a smile to start the day. We love this clock so much, we plan to buy more to give as gifts. We’re sure the recipients will love it as much as we do.”
