What Else Can I Do with Air?
How about attaching an oscillating fan to a triggered
relay? This would allow you to use air to move ghosts or
other characters clothed in lightweight fabrics that motion
with the slightest breeze. Sometimes a simple solution is
the best. We often have a tendency to make our designs
overly complicated even when an easier method is available.
Keep it as simple as possible. This will keep your costs down
and there will be less to go wrong.
An idea I have that is just waiting for a little time to
experiment with is developing a method to simulate the
chest movement of a character’s breathing. It would use a
heavy duty balloon sealed to a rubber stopper with two
holes for an inlet and outlet. Now, I just need to figure out
the best way to pump in the air and then release it. I don’t
quite know how it will work yet, but I am anxious to give it
If you’ve got an idea about how this might be
accomplished, please share it by posting it in the forums in
the new DIY Animatronics thread at
http://tinyurl.com/nvpa53g. I would like for us to take
advantage of all the incredibly knowledgeable builders we
have here, so post your ideas for all to see (like the ones in
Figure 17 and Figure 18). I am certainly looking forward
to learning from all of you!
Last Thoughts Before
They Blow Away
If this sounds like something you would like to try,
maybe you can add a compressor to your Christmas list and
get started. You will be doing your family a huge favor by
providing them with that perfect gift choice for you (that
line worked with my wife as she surprised me with a
fantastic new compressor, but your mileage may vary).
I am always discovering new ways to utilize
pneumatics. Adding the confidence and knowledge to work
with them will serve you well as you design larger and ever
more complicated characters.
However, like potato chips, do not expect to be
satisfied with a single pneumatic prop. You will want more!
