The 2016 GRITS offseason trophy is based
on the Stronghold Portcullis.
Switch to the right and the portcullis door
rises, switch to the left and it lowers.
If we turn the trophy over, we see the joystick
is actually part of a manual pneumatic valve
that switches the air, which comes from this
regulator – this was built before we had
the mini regulators – and this storage tank.
Over here on the side, we see the air is driving
this pneumatic cylinder which is attached
to the door.
The airflow regulators control the speed
of the door and these sensors detect when
the cylinder is up or down which control the
LED lights to mimic the gameplay.
On the back of the trophy, we see it is driven
by 12 volts DC and up to 100 psi of air.
The top is just textured paint on acrylic,
the door is laser engraved acrylic and the
supports are 1-inch aluminum extrusion.
The base is smoked Lexan bent on a homebrew
hotwire bending fixture.
That’s it!
Just a few simple parts and some creativity
and we have an awesome trophy for the 2016
offseason GRITS Stronghold event!
