BookClock - new member of the Wise Clock family

Don't throw away that carboard box your Monochron was packaged in. You can use it as enclosure for the cheapest (yet) member of the Wise Clock family, currently named "BookClock" (for the reason that it can be placed on a book shelf, among books).

Note: The featured cardboard box is sold by ULine. It has the code ULine S-974 and can be found here.

The BookClock contains only two elements: Wiseduino, of course, and the 8x32 LED display from Sure Electronics. One nifty addition is a tilt sensor that changes what is displayed depending on the clock orientation (standing on the smallest side as a book, or laying flat on the largest side).

To build it, let's start with the enclosure, the cardboard box. With an xacto knife, cut an opening for the display.

The opening, waiting for the display, should look like this:

Stick some scotch tape along the cut lines to strengthen (and also smooth) them.

After inserting the display, attach it to the box with some sticky tape (I used electrical tape).

This is how it looks when standing, as a book on the shelf.

The "guts" of the BookClock is a "hacked" Wiseduino board, which looks like this:

This board does not have the extension (female) headers, since there will be no shield mounted anyway. So I soldered (the required wires of) the 16-wire ribbon cable directly where the headers would have been.

Wires number 15 and 16 of the ribbon are GND and Vcc (5V) respectively. For mechanical reasons I soldered them into D0 and D1, whose lines were previously cut. (I then re-connected D0 and D1 to Vcc and GND respectively, see the red and blue wires.)

The board also has a tilt sensor soldered between analog 0 (A0) and ground. A 10K resistor pulls A0 up (connects it to Vcc).

This is how it looks on the inside (not yet connected to power).
