A metallic finish on the frame offers a bit of sleek style, while twin bells up above help wake you up and keep you on time.
In order to shut off this loud alarm, you have to actually get out of bed and stand on the rug for three seconds. But if you find yourself cheating your alarm by crawling back into bed after those few seconds, you can extend the alarm for up to 30 seconds, ensuring you’ll be much more awake once the blood starts flowing to the other parts of your body.
This Alarm Clock has many features that make it an excellent addition to your nightstand, work station, kitchen counter or end table. The first thing that separates this Alarm Clock from the rest are the two, easily accessible USB ports located directly on the front of the clock.

Waking up might be a little bit more pleasant when you can choose between a buzzer, the radio, or your favorite songs streaming from your smartphone or MP3 player to nudge you out of dreamland. Add to that the fun of seeing the time of day (or night) projected in large, red numerals onto your ceiling — you don't even have to turn your head to figure out how much more sleep you'll get if you can just fall back into slumber right now — and the large LCD display on the clock's face, and you have just some of the features that make the Electrohome Projection Alarm Clock our top pick.
Health chose the Sonic Bomb as one of the best alarm clocks for heavy sleepers, commenting that the flashing lights, loud sound, and bed shaker should "deliver the full sensory message that grave danger awaits unless you get out of bed." Reviews.com likes it as well, although they aren't crazy about the appearance of the clock, claiming it looks like a gag gift. Still, they say, "It won us over with how effective and customizable it is."
Greek astronomer Andronicus of Cyrrhus supervised the construction of the Tower of the Winds in Athens in the 1st century B.C. 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.
Rise and shine, rebel. This Stormtrooper comes to you, bringing news of a peace proposal with the empire. See those bright numbers displayed brilliantly on its LCD screen? That means it's time to go. Adjustable arms point toward the door, beckoning for you to make haste. But before you head off to save the galaxy, you might want to turn your Lego alarm clock off first. Plus, if you're a Darth Vader fan, you can get this alarm clock with him, too!
But where OK to Wake! really shines (pun intended) is in its unique feature that parents love; the clock will glow green and show a cute face when it's an acceptable time for your little one to get out of bed. That means even very young children can learn when it's okay to go looking for mommy or daddy — no need to be able to actually read the time. As your child grows, you can stop using the glow feature, and simply use the device as a regular, albeit cuter than average, alarm clock.
Hang clocks in places where they’ll be most useful, such as the kitchen or above your desk. They should be easily visible and complement the design of the space. Large wall clocks are ideal for over a fireplace, above an entry table or showcased in an art niche. Smaller wall clocks can be added to your kitchen, home office or child’s bedroom to help keep your day on track.
Some clocks, usually digital ones, include an optical projector that shines a magnified image of the time display onto a screen or onto a surface such as an indoor ceiling or wall. The digits are large enough to be easily read, without using glasses, by persons with moderately imperfect vision, so the clocks are convenient for use in their bedrooms. Usually, the timekeeping circuitry has a battery as a backup source for an uninterrupted power supply to keep the clock on time, while the projection light only works when the unit is connected to an A.C. supply. Completely battery-powered portable versions resembling flashlights are also available.
Keep time in style with this traditional tabletop clock, a great way to round out a decorative vignette while adding essential function. Crafted from wood and metal, this circular design sits atop a curved base and pairs an antique dial with a deep red finish. The glass-inlaid clock face sports glow-in-the-dark hands, so you can check the time in the wee hours and early evening, while a quartz movement keeps this design tickin’ and tockin’. Requires a battery.
The invention of the mechanical clock in the 13th century initiated a change in timekeeping methods from continuous processes, such as the motion of the gnomon's shadow on a sundial or the flow of liquid in a water clock, to periodic oscillatory processes, such as the swing of a pendulum or the vibration of a quartz crystal, which had the potential for more accuracy. All modern clocks use oscillation.
“This little beauty works great. I bought it when the alarm on my mobile phone began to intermittently fail me. This little travel clock is beautiful in retro seafoam green and great for travel because its bright color ensures that you will never miss picking it up from your hotel nightstand at checkout. There is a faint, pleasant ticking, the hands glow in the dark, and the nightlight button is bright when needed. The pop-up alarm button is firm and works well though I am learning not to accidentally press it and turn the alarm off when picking up the clock. Overall, a fantastic alarm clock.”
