The Incredible DIY Coffee Can Clock

When we saw this amazing hack, we knew we had to know more about it. It's one of those hacks that involves quite a bit of work, but just to let you know, some parts for this build are available from the creator, so it's not as complicated as that!

This build is by Florinc from the Wise Time With Arduino blog. He though that a coffee can might make a great enclosure for an alarm clock. Lucky for us, this clock almost looks like a piece of art. It has these gigantic LEDs that are just so neat to have around.

The electronics inside are based on the Wiseduino, an arduino clone with a real time clock on board. An LED matrix sits on top of it. Sounds pretty simple, right?

Well, maybe not. What you need to know is that if you really like this clock, you'll be easily able to build your own since Florinc plans to offer it as a kit. This kit is available for $32 here. Meaning that it will be quite easy to put together. There are a bunch of features that make this clock really great. Here is our favorite:

And here is an original feature: three hours before the alarm will sound, the time is shown in orange; one hour before the alarm will sound, the time is shown in red. So just by squinting at the clock, one can realize how much longer one can sleep.
