Arduino Led Alarm Clock

 

This is an original way to hack a dvd-player and integrate it with an allarm-clock. Well, building up a new Digital Alarm Clock with Arduino is the real project, the integration with the DVD-Player is the Hack. Thanks [razrbhr] to send us your project.

Arduino led clock driven directly using an Arduino Mega 2560 board.. Has an in built alarm function and triggers a DVD player via optocouplers to start playing songs when alarm time is reached so you wake up with a smile…

You will find more and the full description of the project, included pictures on his [blog]

New improved I2C library for Arduino

Recently I have been experimenting a lot with I2C. My A.I. project uses the DS1307 RTC and a work project uses several I2C ADC's.

Normally the Arduino Wire library works fine with the DS1307 RTC but it does not play well with 3.3V @ 8MHz devices such as my Micro Magician and does not support fast mode (400KHz). It also has some compatibility issues with some devices such as my ADC's because it does not support a repeated start condition.

Lite Brites fade, but LED clocks are forever

Ahh, the Lite Brite.

What could be more fun than pushing dozens of little plastic pegs through a piece of black paper in order to create a pixelated, though colorful image? Well, I can think of quite a few things more engaging than that, and luckily so can [Lonnie Honeycutt] over at MeanPC.

While contemplating what to build with a pile of LEDs, his daughter came into the room with her portable Lite Brite. He thought that the pegs she was using looked awfully similar to the LEDs on his desk, so he did some test fitting and was surprised to see that they fit almost perfectly.

[Lonnie] thought that the toy would make an excellent clock, and his daughter happily agreed to let Dad do some tinkering. A few hours, an Arduino, and some Charlieplexing later, he had a nice looking clock that his kids were sure to enjoy.

If you’re interested in seeing more about how constructed, be sure to check out his YouTube channel and Instructable, where he happily provides all of the build details.

Foursquare Clock Keeps Tabs on Your Whereabouts

Just in time for today’s celebration of Foursquare Day, Christopher McKirgan created The Foursquare Clock, a servo-driven clock that uses the Foursquare API to let his roommates know where he is and how long ago he checked in there. He created a clock face that includes icons for his most visited locations and an indicator for for how many hours ago he checked in. At the core of the project is an Ethernet-connected Arduino, which controls the servos inside an old fashioned wooden clock. Thanks for sharing Christopher, and Happy Foursquare Day! [via Twitter]

Stand for ClockTHREE

Some time ago I received, as a gift, this smart and very useful stand from fellow clock enthusiast Nicholas in San Diego. He designed it and made it specifically for ClockTHREE. Simple yet elegant, this is essential if you want your C3 on the desk or table.















I did not have the chance to appreciate it until now, with an older ClockTHREE borrowed from a friend (I gave it to him as a gift). Here is the C3 on the stand, a perfect fit!


















Thank you Nicholas! Keep up the great work!

Doodle clock-robot using arduino

Watching the seconds go by is a frightening reminder that time pauses for no one, but somehow, a hacker going by the name of Ekaggrat has figured out how to make the process a bit less daunting. The so-called Doodle Clock is an Arduino-powered robotic arm that’s been trained to jot down the time with a dry erase marker; once the minute passes, he erases the last digit and rewrites it — a number beyond what he just erased.

More of Ekaggrat’s work can be found here.

Watching the seconds go by is a frightening reminder that time pauses for no one, but somehow, a hacker going by the name of Ekaggrat has figured out how to make the process a bit less daunting. The so-called Doodle Clock is an Arduino-powered robotic arm that's been trained to jot down the time with a dry erase marker; once the minute passes, he erases the last digit and rewrites it -- a number beyond what he just erased, of course. Per usual, these things are better seen than read about, so why not hop on past the break and mash play? Smiles await.

Wise Clock 4 Dual screen chronometer

This chronometer, inspired by the Doomsday clock by Wyolum, is made with a Wise Clock 4 board (available for sale here) and two 3216 displays from Sure Electronics.



Its main feature is the odometer-style rolling of the digits when they change.
The time is updated once a second, based on the 1Hz interrupt signal from DS3231, as described here.



















As shown in the video, one button is used to change the display brightness, another button is used for changing the font, and the third is used for switching between rolling style and static style.

By using the bigger (5mm) 3216 displays with the same setup and software, this clock can be easily read from a distance of at least 100 feet (30 meters).

Source code is available here. The current version does not allow setting up the time and date from buttons.
