programming was completed to our satisfaction, there was
still the arduous task of installing all the boards in
protective enclosures. The plastic project boxes from All
Electronics (see Resources) fit the bill perfectly. They were
easily drilled for wire access, and all the cables were
attached using pigtails (when necessary) and securely
anchored to prevent them from coming loose.
The actuator driver circuits were installed on the lid of
the project box which enabled us to combine all the
necessary components into one clean assembly. Chassis
mount power coax connectors were added to each of the
four boxes to ease the hookup chores (see Figure 9 and
The access ports on the boxes were labeled as well as
all the cables. Since this scene will not be permanent and
needs to be broken down for storage, it is paramount that
all connections be clearly labeled to aid in speedy
We used separate power strips with integrated on/off
switches for the servos to reduce any extreme movements
This Show’s Final Scene
This scene will make its debut at our Halloween parties
prior to the holiday itself. This will give us the opportunity
to work out any kinks and be ready for the big night. I
expect a large turnout of expectant trick or treaters looking
to see what new creation we have come up with this year. I
am sure there will be plenty of excitement and maybe even
a few screams! You will be able to view the scene yourself
by checking out the video on my You Tube channel (see
As the complexity of our scenes continues to expand,
the importance of having a team of knowledgeable and
creative builders to collaborate with becomes increasingly
important. I am so grateful to work with individuals such as
Brian who are as passionate about this hobby as I am.
Seeing the joy in our guests faces makes all the time, effort,
and expense worthwhile!
With this challenge being achieved, it is now time to
start brainstorming our next project.
