That awful buzzing/beeping beside the bed in the morning might not seem so bad if it were a cascade of bubbles instead. At least that’s what [Will] is hoping for. He took a child’s toy and turned it into a bubble blowing alarm clock.
We’re guessing you’re not going to be too happy with the alarm settings feature. This isn’t using a real-time clock, or any clock at all really. [Will] rolled his own light detection circuit using a PNP transistor whose base is controlled by an LDR. When the light level in the room reaches a certain threshold the bubbles start streaming out of the front of this thing. He test the system in the video by switching a lamp on and off in a dark room.
Up at dawn has never been a way we could describe ourselves, but the one-wire control method seen here could easily be provided by a microcontroller rather than the LDR. Oh, and for those that don’t get it; the [Lawrence Welk] show always started with a screen full of bubbles.

[linux-dude] always wanted to have a binary clock, but he didn’t want to pay someone else to make it for him. Additionally, he was looking for a compact alarm clock he could take on the road, rather than relying on the one in his hotel room.
Inspired by other binary clock projects he has seen over the years, he set off to build his own, which he wanted to fit inside an Altoids tin. His binary clock uses an Arduino Duemilanove (which fits perfectly in the tin) to keep time and control the indicator LEDs. The LEDs are arranged in two rows as you would expect, representing hours and minutes. A small piezo speaker serves as the alarm buzzer, which should be sufficient to wake up most people, though something bigger might be required for heavy sleepers.
We didn’t see any sort of battery pack or power plug mentioned, so we’re not quite sure how [linux-dude] keeps his clock juiced up. Additionally, the lack of an real time clock is something we’re puzzled by. While the Arduino does have a clock function that can be used, an RTC might serve him better – then again if he’s gone for just a day or two at a time, a small amount of drift may not be an issue.
[Thomas] wrote in to tell us about his latest project, the “AlarmTock”. Like many hacks, this was inspired by some outdated hardware, a radio alarm clock from 1992.
After finally getting fed up with his old alarm clock, [Thomas’] wife purchased him a new one for around $10 from a local retail store. Although most likely an improvement, [Thomas] wondered why after so many years he still had to listen to either an annoying “beep” sound or whatever song the DJ on the radio decided to play.
In true hacker form, he decided to do something about it. [Thomas] crammed a [Chumby Hacker Board], which has much of the same hardware as the [Chumby One] device, into his clock radio. RSS-driven text-to-speech was used to tell him exactly what he wanted to know every morning. A sample .wav file is provided as well as the python script used to execute his morning wakeup routine.

Oversleeping sucks, but we’ve all been there. Whether its a matter of hitting the snooze button a dozen times too many, or turning off the alarm and drifting back to sleep – sooner or later, you are going to wake up late.
Instructables user [nolte919] has overslept a time or two in his life, and he set out to design a clock that would make it nearly impossible to wake up late. His clock is Arduino-based and shares many features with off the shelf models including multiple alarms, a backup battery, and snooze features. His alarm however goes one step further and ensures you are fully awake each morning.
If you hit the user-defined snooze limit, the alarm sounds and will not turn off until you have cleared 4 lines in Tetris. That’s right, you have to prove to the clock that you are awake and coherent before it will shut off. Technically you can silence the alarm for a 30 second period so you can focus on Tetris, but that’s all the break you get.
It really is a novel way of ensuring you are awake in the morning, and heck, how bad can the day be when you start off by playing video games for a few minutes?
Stick around to see a quick video of his Tetris alarm clock in action.

Yep, if you’ve got a button that needs pushing, this is one way to do it. [Travis] combined an old alarm clock with a car door-lock actuator and minimal logic circuitry to make this happen. When the alarm time is reached, the adjustable actuator comes down to press whichever button has been placed under it. In the video after the break he’s using it to schedule the start time for his Roomba, make his coffee, heat his pizza, or pointlessly press the clock’s own snooze button (classic). We think this is just begging to be used with a Rube-goldberg setup, perhaps to topple to dominos that other robot took the time to set up. Oh wait… that shows up in the video too. Fantastic!

It seems everybody has a different interpretation of the perfect alarm clock. [Loic Royer’s] alarm clock is not the loudest, or the smartest, but does have some interesting features. By monitoring several environmental factors like temperature, air quality, humidity, dew point, and your own sleep patterns, this alarm clock can determine the best moment in the morning to wake you up.
The main sensor is a wireless accelerometer with the theory being: the more you move in your sleep, the closer you are to a conscious state. The other sensors assist in picking the perfect moment, and awaken you with the sound of birds chirping.
For now all we have is the source code and the list of hardware, but for anyone wanting to try, a circuit diagram wouldn’t be too hard to figure out on your own. Check after the rift for some more videos. Continue reading “Lolo’s (perfect moment) alarm clock”
While it may sound like a dirty joke, turning off the alarm clock with a wiggle of your joystick is entirely possible here. [Sean] was inspired by the light gun alarm clock featured in Make magazine a while back and decided to build something similar. Instead of going the light gun route, he chose to use a joystick. You set the time on the clock using the joystick and the fire button works as a snooze button. Though it currently doesn’t have a snooze-waggle feature, it could without too much effort.
[Sean]’s server is small. He notes in his comments that he can’t handle the traffic from us. This is why we had to find it our selves instead of him submitting it. Tsk Tsk. To help, we have included the few other pictures of his build after the break. If you really want to overload his poor little server, you’ll find the link to his site here, instead of at the beginning of the article.
