Step 1

On the first PixBlock use solder wick to remove excess solder from the pads for the microcontroller. Then solder the controller to the board.

Step 2

Assemble the three push buttons and the pin header. The pin header is the ISP connector which you will use for programming.

Step 3

The inclination switch is connected between GND (CON5, pin 1) and PA3 (CON5, pin 6). Attach it such that the switch is open when the hourglass is upright, and closed when the hourglass is upside down. To suppress vibrations it might be beneficial to connect a capacitor (e. g. 1 µF) in parallel with the switch.

Step 4

Both PixBlocks are connected with the ribbon cable, where the OUT signals of PixBlock 1 run to the IN signals of PixBlock 2.

Step 5

Finally you assemble the dot-matrix LEDs.
