Ever wanted a binary alarm clock? Me too. So I looked around on Instructables, because there are many good ones around.
What's even better: they're based on the Arduino, one of my favourite toys.

My favourite is this one: http://www.instructables.com/id/Arduino-Binary-Alarm-Clock/. It inspired me a lot and yes I took the code as a base for my project. But this one is far too big for me. I wanted something I can take with me when I visit Hacking Conventions and don't want to miss the early lectures. Nothing is more annoying, if you finally got some tickets for the con, go there and don't wake up after a long (really long.....) hacking and builing night and miss a workshop you'd really want to join.

So what's small enough to fit in a pocket and is also a really great case for projects like this? Yes, an ALTOIDS tin :)

Actually this instructable isn't complete at the moment. First I thought, I'd just share some pictures, but some friends asked for an instructable, so I'll add a detailed how-to the next days.

The pictures on this side are from the first version. You will find newer (but not really better pictures, because my camera died and so I shot a lot of pictures with a crappy web cam or used some for the parts I found on Google) pictures in the following steps.

As said, the pictures are sometimes blurry and crappy. That's why I've entered this to the pocket-sized contest. I really need a new camera.... ;) Please vote 4 me :)

That's awesome. I love the pro mini's. I'm currently building one inside an alarm clock housing, making use of the existing switches, buttons, and alarm speaker.

Great! Hope you'll post an instructible on it or at least some more pictures. Would be a nice wrist watch :)

Here some pictures, I've added buttons
The only thing left is a battery and fix on few code glitches.

As for a guide how to make it is pretty much the same you only have to solder carefully and re-arrange some pins assignment.

ps (used 1mm 3v leds, 330 ohm resistors but i would suggest 400ohm)

Hi! Great Project. I was wondering how you were planning on making the touch sensor.

Hi, thx :) The touch sensor will be integrated in the next version. I think it'll be mounted somewhere on the top of the tin. At the moment I'm working on a nicer sound output. I want to add a Commodore SID chip to play some music files instead of the annoying Piezo beeps.
I am having a hard time soldering the headers in with out having a pad to solder to and also did you have to drill out the holes because the holes in my perfboard are not lining up with the holes on my arduino?

Awesome!
