Waking Up With The (fake) Sun

July 9, 2010 by Mike Szczys 38 Comments

[Bogdan] has some trouble getting up in the morning. A blaring alarm will do the trick but that’s no way to start the day. To get him through the dark winter months he wanted to try a sunrise simulator. He patched into the alarm signal of his bedside clock, intercepting the command from the clock’s microprocessor and using it as an input for his own ATtiny13. From there, the tiny13 gradually brightens a 150W halogen lamp using a triac until his room is as bright as a July morning. A signal is then sent to the alarm clock’s audio amplifier to turn on the audible alarm. He’s got the system set for a 20-minute sunrise so it’s just a matter of programming his alarm 20-minutes early than the ‘I absolutely have to get out of bed now’ time.

Intruder Alarm McDonald’s Toy Hacking

April 8, 2010 by Caleb Kraft 14 Comments

[malikaii] needed to set up some kind of tripwire style alarm system for his office. His bosses kept sneaking in to find him slacking. So, like any loyal hacker, instead of just working harder he built an alarm system. After a failed attempt to recreate an IR alarm circuit he found on the web and built from old appliance parts, he found the Hack a Day article about harvesting McDonald’s toys. The end result was a fully functional IR detecting alarm for the office doorway. This is pretty simple really, the best kind of hack.

PC Fan Failure Alarm

Need to monitor not only if a fan is running, but if it is running fast enough? Check out this PC fan failure alarm circuit. After several failed attempts using various circuits, they settled on a Schmitt trigger. They even show a couple variations including a manual reset and a relay instead of a buzzer.

Time Delay Door Alarm

March 6, 2010 by Caleb Kraft 21 Comments

Ever accidentally left your front door ajar and had a pet escape? [BlackCow] came up with a simple solution to this problem. The circuit is fairly rudimentary but a great example of using the basics to get the job done. Now, instead of having an alarm that sounds as soon as the door is open, he has a 30 second delay. This helps avoid the “boy who cried wolf” effect also known as the “vista security warning” effect of being bothered too many times for a non issue. We also have to say that we like his taste in blog layouts.

Gentle Wake Up Alarm

February 22, 2010 by Caleb Kraft 37 Comments

[Michiel], unsatisfied by his Phillips wake up light, decided just to make his own. He really wanted programmable weekend alarms as well as an easier to find snooze button. At first, his circuit was not reliable enough, losing several minutes per hour, but he gutted another alarm for the 1Hz crystal. After some carpentry, his final alarm ended up quite nice. After so many aggressive alarm clocks, it’s nice to see that not everyone needs to be assaulted out of bed.

Correction: apparently, there’s no 1Hz crystal. That was a guess on my part. -[Caleb]

Clocks That Only A Geek Could Love

December 18, 2009 by Mike Szczys 15 Comments

Alpha-Geek Clock

Oh this one’s good! This clock has a built-in WWVB receiver to make sure the time is always accurate. But with just one LED as the display we wish you good luck when reading it! A whole bunch of info (time, day, year, etc) is blinked out in binary encoded decimal. [Thanks Tymm]

Standard Time

Manual labor. This clock is an art installation in Rotterdam. In the video you can see that workers changed the segments of a four-digit display every minute over a twenty-four hour period. Since they filmed it we’d expect the ability to turn this into a video clock like the one we saw last week. [Thanks David]

International Clock

Low-tech but highly creative. The instructional video uses basic geometry and the workings from a cheap clock to craft an international clock. There are twelve labels corresponding to different time zones. Put the zone you want up and read the clock as normal. [via Red Ferrett Journal]

Princess and the Pea

There are few who will agree to have an air tank as part of an alarm clock. The Princess and the Pea concept uses compressed air to inflate an exercise ball in between the mattress and the box spring. Watch this video to see how it will roll you out of bed if the hissing air sound didn’t wake you first. At least it’s more gentle than the pneumatic alarm clock from last June. [via Neatorama]

Mr. Wake, Wakes Up And Runs

[isotope] must really hate himself. He has built a torture device of pure evil. Mr. Wake, his alarm clock robot, should be considered a torture device. This cute looking little bot, with its bright and colorful clock and neat plastic tube frame is an alarm clock. As soon as it’s alarm goes off, Mr. Wake starts watching for you. If it detects your presence, it takes off, only to wait for you to stumble, bleary eyed, to its current location. Do you know what it does when you catch up to it? It takes off again. Why would you build a robot that you know you are just going to destroy in a groggy fit of animalistic rage?

We actually like Mr. Wake more than clocky, simply for its hackish feel. If you really really have problems getting up, you may want to consider something a little more drastic.
