Pop- Up Part 4 - Assembly
At left is a photo of the motion Detectingunit that will be used with the Vile Things
Simple Pop- Up.
The PIR sensor head is from a
"Regent" outdoor lighting kit.
It detects rapid changes in temperature,
and activates a relay upon detection.
This model has a 4 second test mode, as well as
"1 minute" and "5 minute" run modes.
I opened the sensing head and disconnected the relay
from the AC contact voltage.
The PIR sensor still requires standard household voltage for operation,
but the relay now switches what ever I put into it, which, in this case is
12 volts DC - the output voltage of my home-made event control timer unit.
The metal "handi-box" at right will always be "hot."
This will supply power to the PIR motion Sensor head and the
timing unit.
Upon detection, the timer unit will delay for 10 seconds, then
run for ten seconds. The 3 prong receptacle on the timer unit is wired to be
"hot" only when the unit is in the"on" mode.
By setting the PIR sensor head to the "1 minute" time,
I will have approx. 40 seconds of "off time," during which time the
prop cannot be re-triggered.
I mounted the PIR sensor head
to an adjustable linkage. This will
allow me to position the viewing
lens wherever it will
be the most effective
(and least visible.)
He looked kind-of lonely, so I built him a couple of pals.
(actually it's part of the set design.)
These guys don't do anything, they just provide
moral support. The building process was identical
to that of the 2002 Pop-Up, without any mechanical,
pneumatic, or electronic parts.
These are very similar to "Monster Mud" props,
without the mud.
They each weigh less than twenty pounds.
In order to guarantee no haunt visitors will come
close to the Pop-up prop, I built a section
of p.v.c. fence. At a finished height of
37 inches, it would be difficult to simply
walk over. The bars are spaced 6 inches apart,
so even little folks can't accidentally walk through.
Here's a sneak peek at the pop-up room during daylight hours.
Before... ...and after.
Night time photos are NOT my thing, but you get the idea.
