With the Raspberry Pi as the control system for the balloon payload, there are many
potential areas of improvement, including adding more cameras, adding a servo-
controlled camera to control where it is pointed, improving data transmission, and
adding even more sensors.

Have the Best Holiday Lights Display
HACK 45
You've probably seen a YouTube video of somebody with an animated
holiday light display, putting the rest of the neighborhood to shame (and
possibly torturing the people across the street). If your aspirations in life
include being Clark Griswold, then this hack is for you.
The Raspberry Pi's GPIO makes controlling up to 17 changing sequences of lights easy.
Your neighbors' sanity and your power bill are your only limits! Your setup consists of
a Raspberry Pi connected to a relay board via a level converter, as shown in
Figure 4-14
.
